Hydrologic Soil Group—Larimer County Area, Colorado
Description
Hydrologic soil groups are based on estimates of runoff potential. Soils are
assigned to one of four groups according to the rate of water infiltration when the
soils are not protected by vegetation, are thoroughly wet, and receive precipitation
from long -duration storms.
The soils in the United States are assigned to four groups (A, B, C, and D) and
three dual classes (A/D, B/D, and C/D). The groups are defined as follows:
Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly
wet. These consist mainly of deep, well drained to excessively drained sands or
gravelly sands These soils have a high rate of water transmission.
Group B. Soils having a moderate infiltration rate when thoroughly wet. These
consist chiefly of moderately deep or deep, moderately well drained or well drained
soils that have moderately fine texture to moderately coarse texture. These soils
have a moderate rate of water transmission.
Group C. Soils having a slow infiltration rate when thoroughly wet. These consist
chiefly of soils having a layer that impedes the downward movement of water or
soils of moderately fine texture or fine texture. These soils have a slow rate of water
transmission.
Group D. Soils having a very slow infiltration rate (high runoff potential) when
thoroughly wet. These consist chiefly of clays that have a high shrink -swell
potential, soils that have a high water table, soils that have a claypan or clay layer
at or near the surface, and soils that are shallow over nearly impervious material.
These soils have a very slow rate of water transmission.
If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is
for drained areas and the second is for undrained areas. Only the soils that in their
natural condition are in group D are assigned to dual classes.

B. Identification of Potential Pollution Sources
The permit identifies 13 potential sources that must be evaluated for their potential to
contribute pollutants to stormwater discharge. These items have been evaluated below
for this project (this initial assessment shall be reviewed and modified by the permit
holder):
1) Disturbed and stored soil — YES — The construction will require that areas
be disturbed exposing soil including concrete pouring, helical bridge
construction, and slope construction as shown on the plans. BMPs will
include silt fence between areas of cut and fill (more than 6 inches) and
existing vegetation, a rock check dam on the downhill side of the 36"
culvert ditch crossing, minimizing disturbance of existing vegetation and
hard surfaces with the use of a delineated limits of disturbance boundary,
and slope roughening and tracking of slopes after disturbance and prior to
landscaping. A windrow will be utilized to keep soil from moving down
slopes that do not need silt fence
2) Vehicle tracking of sediment - YES — The construction will require that
subgrade be prepared for trail construction and that vehicles drive on
unpaved surfaces along the tail alignment. BMPs will include three
vehicle tracking pads, one located off the existing edge of pavement at
Keenland Drive, a second at the connection to Southridge Greens
Boulevard, and the third will be located just north of Trilby Road. Any
muddy vehicle will use the vehicle tracking pad prior to leaving the site. If
mud is tracked off site the Contractor will remove it in the following
manner: (CONTRACTOR TO SPECIFY HERE)
3) Management of contaminated soil — NO — Soil borings do not indicate any
existing contamination.
4) Loading and unloading operations — YES — Chemicals and petroleum
products will be brought to the site. Anytime these are being transported,
they will be in a sealed container.
5) Outdoor storage activities — NO — There are no materials that are
anticipated to be stored on site.
6) Vehicle and equipment maintenance and fueling — YES — Vehicle
maintenance and fueling will take place at the north end of the site just off
the existing edge of pavement of Keenland Drive. No fuel will be stored
on site; a fuel truck will deliver fuel directly to equipment as needed. The
largest risk to stormwater with this operation is pollutants being spilled on
the existing ground. Absorbent (CONTRACTOR TO SPECIFY
HERE) will be in the construction trailer and applied on any spill
immediately and the dry material disposed of properly and legally.
7) Significant dust or particulate generating processes — NO — The trail
8
construction only includes grading and concrete pouring and none of the
operations are expected to generate significant dust.
8) Routine maintenance activities involving fertilizers, pesticides, detergents,
fuels, solvents, oils, etc. — YES — Fertilizers and pesticides will not be
used. Any cleaning or maintenance of small equipment that cannot be
done at the concrete washout will be required to be done within a
containment device (CONTRACTOR TO SPECIFY HERE) and the
liquid disposed of properly and legally.
9) On -site waste management — NO — There is no demolition associated with
this project.
10) Concrete truck/equipment washing — YES — A concrete washout will be
provided at the same three locations as the vehicle tracking control: east of
Keenland Drive, at the proposed walk connection to Southridge Greens
Blvd. and the connection north of Trilby Road. This will be used for
trucks and for any concrete tools.
11) Dedicated asphalt of concrete batch plants — NO — None on this project.
12) Non-structural. waste sources such as worker trash and portable toilets —
YES — A trashcan will be at the construction trailer and will be emptied
weekly. A portable toilet will be located at (CONTRACTOR TO
SPECIFY HERE) on a gravel pad.
13) Other areas where potential spills can occur — NO — The above 12 items
are adequate for the anticipated construction process.
C. BMPs for Stormwater Pollution Prevention
1) Structural Practices for Erosion and Sedimentation Control: Structural
Practices to control soil movement on this site will include silt fence along
both sides of the trail where significant grading will take place (cut/fill
greater than 6 inches). Silt fence will also be used near the Mail Creek
Ditch crossing. A windrow will be utilized to keep soil from moving
down slopes that do not need silt fence. A rock check dam will be used at
the downstream end of the 36-inch culvert at the proposed ditch crossing.
These are the locations where disturbed soil could reach the site
boundaries and adjacent waterways.
These BMP's shall be installed per the included City of Fort Collins
Details. They shall be inspected per the permit requirements and repaired
or rebuilt to maintain their effectiveness. Even without a formal
inspection, if the BMP does not appear to be operating properly, the
SMWP Administrator shall be notified and repairs begun immediately.
They shall be removed and disposed of immediately upon final
stabilization of the area that drains to the BMP.
W
2) Non -Structural Practices for Erosion and Sedimentation Control: All low
sloped areas exposed during land disturbing activity (stripping, grading,
stockpiling, filling, etc.) shall be kept in a roughened condition by ripping
or disking along land contours until mulch, vegetation or other permanent
erosion control is installed.
All exposed steep sloped areas exposed during land disturbing activity
(stripping, grading, stockpiling, filling, etc.) shall have slope protection.
The contractor shall use a "tracked" vehicle, run perpendicular to slope to
inhibit rill/gully erosion; the contractor may use other windrow -type
methods as necessary.
Permanent erosion control (hard surface or mulch and seed) shall be
installed as soon as practical. No soil (not being actively constructed
upon) shall remain exposed by land disturbing activity for more than
fourteen (14) days.
If the above methods do not prove adequate, it may be necessary for
erosion blankets, mats, or mulch to be placed on disturbed areas and the
S WMP amended.
3) Phased BMP Implementation: The Construction Schedule discussing
phases of construction and the required BMP's is included in the
Appendix. Site maps will be modified / updated as construction occurs in
accordance with the permit which will following the schedule and the
phasing of the actual construction.
4) Materials Handlingand nd Spill Prevention:
Potential impacts from significant materials and their handling are as
follows:
Chemicals, cleaning substances, and petroleum products related to the
construction will be stored inside.
Fueling and maintenance of equipment shall take place in the northern
entrance to the site off the existing pavement at Keenland Drive. Fueling
will be accomplished with fueling trucks on an as needed basis.
Absorbent (CONTRACTOR TO SPECIFY HERE) will be in the
construction trailer and applied on any spill immediately and the dry
material disposed of properly and legally.
All construction waste shall be disposed of in the available trash receptical
throughout the workday. Liquid wastes will be hauled off site and
OCi
disposed of properly and legally.
Any cleaning or maintenance of small equipment that cannot be done
inside the concrete washout will be required to be done within a
containment device (CONTRACTOR TO SPECIFY HERE) and the
liquid disposed of properly and legally.
In the event of any spill, the SWMP Administrator shall be immediately
notified.
Spills can be broken into three categories. Their definitions and the
procedures required to address the spills are as follow:
Minor Spill — A spill generally of less than 5 gallons which is unlikely to
reach adjacent waters (i.e. equipment leak).
Procedure:
a. Stop the source of the spill.
b. Contain the spillage.
c. Contact the SWMP Administrator.
d. Clean up the spill with on site absorbent material.
e. Dispose of the dry material property or legally.
f. Document the spill and the response in the SWMP including dates
and times — verify that the pollutants are completely cleaned up.
g. Include incident in the following training meeting.
h. Provide information to the City of Fort Collins at the next regular
inspection.
Significant Spill — A spill of pollutants or oils of any size that will likely
or has reached adjacent waters, may endanger health or the environment,
or which may cause an exceedance of a water quality standard.
Procedure:
a. Stop the source of the spill.
b. Contain the spillage.
c. Contact the SWMP Administrator.
d. Clean up the spill with on site absorbent material.
e. Dispose of the dry material property or legally.
f. Document the spill and the response in the SWMP — verify that the
pollutants are completely cleaned up.
g. Notify the City of Fort Collins, contact Craig Kisling (970) 221-
6367 and the Colorado Department of Public Health and
Environment spill reporting line (877) 518-5608 of the spill.
11
h. Notify the same two entities above with a written submission
(outlined within the permit) within 5 calendar days.
i. Include incident in the following training meeting.
Hazardous Spill — A , spill of a dangerous substance requiring expert
cleanup.
Procedure:
a. Secure the area — do not approach the spill.
b. Offer first aid to any injured parties.
c. Call 911 and describe the nature of the spill and any injuries.
d. If possible, isolate downstream areas from the spill (for example,
cover an inlet that is downstream and a safe distance from the spill
with plastic and soil).
e. Contact the SWMP Administrator.
f. Document the spill and the response in the SWMP
g. Notify the City of Fort Collins, contact Craig Kisling (970) 221-
6367 and the Colorado Department of Public Health and
Environment spill reporting line (877) 518-5608 of the spill.
h. Notify the same two entities above with a written submission
(outlined within the permit) within 5 calendar days.
i. Include incident in the following training meeting.
5) Dedicated Concrete of Asphalt Batch Plants: There will be no plants
located on the site.
6) Vehicle Tracking Control:
Vehicles shall be clean of sediment prior to entering the site.
Any vehicle containing sediment will use the vehicle tracking pad prior to
leaving the site.
Keeneland Drive, Southridge Greens Blvd, and Trilby Road shall be
inspected at the end of each workday and immediately cleaned of any mud,
sediment or debris by (CONTRACTOR TO SPECIFY HERE)
7) Waste Management Disposal, Including Concrete Washout: All waste
materials and construction debris will be removed from the site by means
of (CONTRACTOR TO SPECIFY HERE). No construction materials
(including broken concrete) will be buried on -site.
The portable toilet will be located (CONTRACTOR TO SPECIFY
HERE) on a gravel pad.
12
It is prohibited to wash concrete trucks and pump rigs into the storm
drainage system or onto the ground surface. A concrete washout area will
be constructed for the washout of concrete truck mixers, pump rigs and
tools. Signs shall be placed at the site entrance, at the washout area and
where necessary to clearly indicate the location of the concrete washout
area. The concrete washout area will have a temporary pit or bermed area
large enough to contain all liquid and waste concrete materials from
washout. Washout area will be inspected weekly, during and after any
storm event. It will be cleaned out when two-thirds full or as necessary to
maintain capacity for wasted concrete. At the end of construction, all
hardened concrete shall be removed from the site..
8) Groundwater or Stormwater Dewatering: Any dewatering of groundwater
for the construction shall be properly permitted with the State, including
monitoring. Any excavations on the site will be accomplished in a fashion
that will prevent upstream areas from draining into the trench or
excavation and thus requiring dewatering. Surface runoff will be diverted
away from any excavation to prevent the need to dewater from stormwater
entering an excavation. This will be accomplished by providing a berm on
the uphill side of any excavation.
13
4. FINAL STABILIZATION AND LONG TERM STORMWATER
MANAGEMENT
Final Stabilization for this site will be achieved with the establishment of seed along with
the completed site improvements (concrete trail). Final stabilization shall be considered
achieved once all proposed site improvements are in place, all vegetation is established,
all temporary BMPs are removed, and that downstream conveyances are inspected and
certified to be clean and free from any construction debris resulting from the construction.
Areas controlled by grass sod will be considered established upon the completion of the
sod installation. Seeded areas will be considered established when vegetation is 70% of
original coverage. The anticipated final stabilization date is included in the Construction
Schedule in the Appendix.
After the site is stabilized and temporary BMP's are removed, a completed .Inactivity
Notice to the Colorado Department of Public Health and Environment — Water Quality
Control Division will be sent. A copy of this Notice will also be sent to the City of Fort
Collins.
After stabilization, there are no other long term, permanent BMPs proposed within the
site other than routine maintenance of the site (landscape mowing, trail maintenance,
etc.).
14
5. INSPECTION AND MAINTENANCE
Site inspections will be performed to effectively address maintenance, repair, and
adequacy of BMPs. The site inspections will be performed by the SWMP Administrator
or his designee a minimum of once every fourteen (14) calendar days on active
construction sites and within 24 hours after a significant storm event (an event causing
erosion). As part of the site inspections the inspector will keep documentation of all
inspections and BMP maintenance, including updated Site Maps indicating new BMPs or
the removal of BMPs since the previous inspection. Blank Site Maps will be utilized and
will be redlined by the SWMP Administrator throughout construction to note all BMPs,
pollutant sources, storage locations, etc.
Any maintenance, repair, or necessary installation of BMPs that are noted during the
inspection must begin immediately. The modifications shall be noted in the SWMP and
the action taken as a result of the inspection shall be noted and certified on or attached to
the original inspection report (date and time that the repair or change was started and
finished and a certification that it was done properly).

6. SWMP IMPLEMENTATION
It is the responsibility of the permittee to operate and maintain all facilities and systems of
treatment and control which are installed to achieve compliance with the conditions of the
permit. This includes effective performance, adequate funding, adequate staffing and
training, etc. (see permit).
All personnel on the construction site who will be in a position to affect or be affected by
the SWMP shall be trained prior to beginning work. These individuals will be given
general orientation information regarding the project and SWMP, shown where the
SWMP is physically located, the SWMP will be explained to them and available for their
review, and the enforcement policy will be reviewed. After this training, a certification
that the employee or subcontractor's employee is familiar with the document and its
procedures will be signed. Copies of these certifications are included in the Appendix.
Throughout the construction, as a part of a weekly safety meeting, the SWMP will be
reviewed with all attendees and any incidents discussed. All attendees shall be logged.
If the SWMP Administrator is made aware of a person(s) intentionally or unintentionally
violating the SWMP or Permit, the following actions will be taken: (contractor can
modify this as appropriate)
1) First incident — written warning with copy documented in SWMP and given to
employer (if subcontractor).
2) Second incident — suspended from site for seven days.
3) Third incident — suspended from site completely.
4) If any subcontractor has three incidents (even with three different employees) the
subcontractor will be suspended from the site.
During construction, the SWMP will be located (CONTRACTOR TO SPECIFY
HERE)
For a period of 3 years after the Permit Inactivity Notice is received by the State, the
SWMP will reside with the City of Fort Collins Park Planning and Development office
(215 N Mason Street, Fort Collins, Colorado 80524).

PART I
A. COVERAGE UNDER THIS PERMIT
1. Authority to Discharge
Under this permit, facilities are granted authorization to discharge stormwater associated with construction activities into
waters of the state of Colorado. This permit also authorizes the discharge of specific, allowable non-stormwater discharges,
in accordance with Part I.D.3 of the permit, which includes discharges to the ground. This includes stormwater discharges
from areas that are dedicated to producing earthen materials, such as soils, sand and gravel, for use at a single construction
site (i.e., borrow or fill areas). This permit also authorizes stormwater discharges from dedicated asphalt batch plants and
dedicated concrete batch plants. (Coverage under the construction site permit is not required for batch plants if they have
alternate CDPS permit coverage.) This permit does not authorize the discharge of mine water or process water from such
areas.
a) Applicable Sections: In accordance with Part I.A.3 of this permit.. some.parts of this permit do not apply to sites
covered under a Qualifying Local Program, as defined in I.A.2.d. For sites not covered by a Qualifying Local
Program, all parts of the permit apply except Part I.A.3. The permittee will be responsible for determining and then
complying with the applicable sections.
b) Oil and Gas Construction: Stormwater discharges associated with construction activities directly related to oil and
gas exploration, production, processing, and treatment operations or transmission facilities are regulated under the
Colorado Discharge Permit System Regulations (5CCR 1002-6.1), and require coverage under this permit in
accordance with that regulation. However, references in this permit to specific authority under the Federal Clean
Water Act (CWA) do not apply to stormwater discharges associated with these oil and gas related construction
activities, to the extent that the references are limited by the federal Energy Policy Act of 2005.
2. Definitions
a) Stormwater: Stormwater is precipitation -induced surface runoff.
b) Construction activity: Construction activity refers to ground surface disturbing activities, which include, but are
not limited to, clearing, grading, excavation, demolition, installation of new or improved haul roads and access
roads, staging areas, stockpiling of fill materials, and borrow areas. Construction does not include routine
maintenance to maintain original line and grade, hydraulic capacity, or original purpose of the facility.
c) Small construction activity: Stormwater discharge associated with small construction activity means the discharge
of stormwater from construction activities that result in land disturbance of equal to or greater than one acre and less
than five acres. Small construction activity also includes the disturbance of less than one acre of total land area that
is part of a larger common plan of development or sale, if the larger common plan will ultimately disturb equal to or
greater than one and less than five acres.
d) Qualifying Local Program: This permit includes conditions that incorporate qualifying local erosion and sediment
control program (Qualifying Local Program) requirements by reference. A Qualifying Local Program is a municipal
stormwater program for stormwater discharges associated with small construction activity that has been formally
approved by the Division.
Other Definitions: Definitions of additional terms can be found in Part I.E. of this permit.
3. Permit Coverage Without Application — for small construction activities under a Qualifying Local Program only
If a small construction site is within the jurisdiction of a Qualifying Local Program, the operator of the construction
activity is authorized to discharge stormwater associated with small construction activity under this general permit without
the submittal of an application to the Division.
a) Applicable Sections: For sites covered by a Qualifying Local Program, only Parts 1.A.1, 1.A.2, 1.A.3, I.D.1, I.D.2,
I.D.3, I.D.4, I.D.7, I.D.8, I.D.1 I, I.E and Part II of this permit, with the exception of Parts ILA.1, II.B.3, II.B.8, and
ILB10, apply.

A. COVERAGE UNDER THIS PERMIT (cont.)
b) Local Agency Authority: This permit does not pre-empt or supersede the authority of local agencies to prohibit,
restrict, or control discharges of stormwater to storm drain systems or other water courses within their jurisdiction.
c) Permit Coverage Termination: When a site under a Qualifying Local Program has been finally stabilized,
coverage under this permit is automatically terminated.
d) Compliance with Qualifying Local Program: A construction site operator that has authorization to discharge
under this permit under Part I.A.3 shall comply with the requirements of the Qualifying Local Program with
jurisdiction over the site.
e) Full Permit Applicability: The Division may require any operator within the jurisdiction of a Qualifying Local
Program covered under this permit to apply for and obtain coverage under the full requirements of this permit. The
operator must be notified in writing that an application for full coverage is required. When a permit certification
under this permit is issued to an operator that would otherwise be covered under Part I.A.3 of this permit, the full
requirements of this permit replace the requirements as per Part I.A.3 of this permit, upon the effective date of the
permit certification. A site brought under the full requirements of this permit must still comply with local
stormwater management requirements, policies or guidelines as required by Part I.D. Lg of this permit.

A. COVERAGE UNDER THIS PERMIT (cont.)
If the new responsible party will not complete the reassignment form, the applicable portion of the permitted site may be
removed from permit coverage upon written request to the Division if the permittee has no legal responsibility, through
ownership or contract, for the construction activities at the portion of the site. In this case, the new owner or operator
would be required to obtain permit coverage separately.
Sale of Residence to Homeowners
For residential construction only, when a residential lot has been conveyed to a homeowner and all criteria in paragraphs
a through e, below, are met, coverage under this permit is no longer required and the conveyed lot may be removed from
coverage under the permittee's certification. At such time, the permittee is no longer responsible for meeting the terms and
conditions of this permit for the conveyed lot, including the requirement to transfer or reassign permit coverage. The
permittee remains responsible for inactivation of the original certification.
a) The lot has been sold to the homeowner(s) for private residential use;
b) the lot is less than one acre of disturbed area;
c) all construction activity conducted by the permittee on the lot is completed;
d) a certificate of occupancy (or equivalent) has been awarded to the home owner; and
e) the SWMP has been amended to indicate the lot is no longer covered by permit.
Lots not meeting all of the above criteria require continued permit coverage. However, this permit coverage may be
transferred (Part I.A.7, above) or reassigned (Part I.A.8, above) to a new owner or operator.
10. Permit Expiration Date
Authorization to discharge under this general permit shall expire on June 30, 2012. The Division must evaluate and
reissue this general permit at least once every five years and must recertify the permittee's authority to discharge under the
general permit at such time. Therefore, a permittee desiring continued coverage under the general permit must reapply by
March 31, 2012. The Division will initiate the renewal process; however, it is ultimately the permittee's responsibility to
ensure that the renewal is submitted. The Division will determine if the permittee may continue to operate under the terms
of the general permit. An individual permit may be required for any facility not reauthorized to discharge under the
reissued general permit.
11. Individual Permit Criteria
Various criteria can be used in evaluating whether or not an individual (or alternate general) permit is required instead of
this general permit. This information may come from the application, SWMP, or additional information as requested by
the Division, and includes, but is not limited to, the following:
a) the quality of the receiving waters (i.e., the presence of downstream drinking water intakes or a high quality fishery,
or for preservation of high quality water);
b) the size of the construction site;
c) evidence of noncompliance under a previous permit for the operation;
d) the use of chemicals within the stormwater system; or
e) discharges of pollutants of concern to waters for which there is an established Total Maximum Daily Load (TMDL).
In addition, an individual permit may be required when the Division has shown or has reason to suspect that the
stormwater discharge may contribute to a violation of a water quality standard.

permit.
c) Bulk storage structures for petroleum products and any other chemicals shall have secondary containment or
equivalent adequate protection so as to contain all spills and prevent any spilled material from entering State waters.
d) No chemicals are to be added to the discharge unless permission for the use of a specific chemical is granted by the
Division. In granting the use of such chemicals, special conditions and monitoring may be addressed by separate
correspondence.
e) The Division reserves the right to require sampling and testing, on a case -by -case basis, in the event that there is
reason to suspect that compliance with the SWMP is a problem, or to measure the effectiveness of the BMPs in
removing pollutants in the effluent. Such monitoring may include Whole Effluent Toxicity testing.
f) All site wastes must be properly managed to prevent potential pollution of State waters. This permit does not
authorize on -site waste disposal.
g) All dischargers must comply with the lawful requirements of federal agencies, municipalities, counties, drainage
districts and other local agencies regarding any discharges of stormwater to storm drain systems or other water
courses under their jurisdiction, including applicable requirements in municipal stormwater management programs
developed to comply with CDPS permits. Dischargers must comply with local stormwater management
requirements, policies or guidelines including erosion and sediment control.
BMP Implementation and Design Standards
Facilities must select, install, implement, and maintain appropriate BMPs, following good engineering, hydrologic and
pollution control practices. BMPs implemented at the site must be adequately designed to provide control for all potential
pollutant sources associated with construction activity to prevent pollution or degradation of State waters.

D. TERMS AND CONDITIONS (cont.)
Prohibition of Non-Stormwater Discharges
a) Except as provided in paragraphs b, c, and d below, all discharges covered by this permit shall be composed
entirely of stormwater associated with construction activity. Discharges of material other than stormwater must
be addressed in a separate CDPS permit issued for that discharge.
b) Discharges from the following sources that are combined with stormwater discharges associated with construction
activity may be authorized by this permit, provided that the non-stormwater component of the discharge is identified
in the SWMP (see Part I.C.I.g of this permit):
- emergency fire fighting activities - landscape irrigation return flow
- uncontaminated springs
c) Discharges to the ground of concrete washout water from washing of tools and concrete mixer chutes may be
authorized by this permit, provided that:
1) the source is identified in the SWMP;
2) BMPs are included in the SWMP in accordance with Part I.C.3(c)(7) and to prevent pollution of groundwater in
violation of Part I.D. La; and
3) these discharges do not leave the site as surface runoff or to surface waters
d) Discharges to the ground of water from construction dewatering activities may be authorized by this permit,
provided that:
1) the source is groundwater and/or groundwater combined with stormwater that does not contain pollutants in
concentrations exceeding the. State groundwater standards in Regulations 5 CCR 1002-41 and 42;
2) the source is identified in the SWMP;
3) BMPs are included in the SWMP, as required by Part I.C.3(c)(8); and
4) these discharges do not leave the site as surface runoff or to surface waters.
Discharges to the ground from construction dewatering activities that do not meet the above criteria must be covered
under a separate CDPS discharge permit. Contaminated groundwater requiring coverage under a separate CDPS
discharge permit may include groundwater contaminated with pollutants from a landfill, mining activity, industrial
pollutant plume, underground storage tank, or other source.
4. Releases in Excess of Reportable Quantities
This permit does not relieve the permittee of the reporting requirements of 40 CFR 110, 40 CFR 117 or 40 CFR 302. Any
discharge of hazardous material must be handled in accordance with the Division's Noncompliance Notification
Requirements (see Part II.A.3 of the permit).
SWMP Requirements
a) SWMP Preparation and Implementation: The SWMP shall be prepared prior to applying for coverage under the
general permit, and certification of its completion submitted with the application. The SWMP shall be implemented
prior to commencement of construction activities. The plan shall be updated as appropriate (see paragraph c,
below), below). SWMP provisions shall be implemented until expiration or inactivation of permit coverage.
b) SWMP Retention Requirements: A copy of the SWMP must be retained on site unless another location, specified
by the permittee; is approved by the Division.
c) SWMP Review/Changes: The permittee shall amend the SWMP:
1) when there is a change in design, construction, operation, or maintenance of the site, which would require the
implementation of new or revised BMPs; or
2) if the SWMP proves to be ineffective in achieving the general objectives of controlling pollutants in stormwater
discharges associated with construction activity; or
PART I
Permit - Page 12
Permit No. COR-030000
D. TERMS AND CONDITIONS (cont.)
3) when BMPs are no longer necessary and are removed.
SWMP changes shall be made prior to changes in the site conditions, except as allowed for in paragraph d, below.
SWMP revisions may include, but are not limited to: potential pollutant source identification; selection of
appropriate BMPs for site conditions; BMP maintenance procedures; and interim and final stabilization practices.
The SWMP changes may include a schedule for further BMP design and implementation, provided that, if any
interim BMPs are needed to comply with the permit, they are also included in the SWMP and implemented during
the interim period.
d) Responsive SWMP Changes: SWMP changes addressing BMP installation and/or implementation are often
required to be made in response to changing conditions, or when current BMPs are determined ineffective. The
majority of SWMP revisions to address these changes can be made immediately with quick in -the -field revisions to
the SWMP. In the less common scenario where more complex development of materials to modify the SWMP is
necessary, SWMP revisions shall be made in accordance with the following requirements:
1) the SWMP shall be revised as soon as practicable, but in no case more than 72 hours after the change(s) in
BMP installation and/or implementation occur at the site, and
2) a notation must be included in the SWMP prior to the site change(s) that includes the time and date of the
change(s) in the field, an identification of the BMP(s) removed or added, and the location(s) of those BMP(s).
6. Inspections
Site inspections must be conducted in accordance with the following requirements and minimum schedules. The required
minimum inspection schedules do not reduce or eliminate the permittee's responsibility to implement and maintain BMPs
in good and effective operational condition, and in accordance with the SWMP, which could require more frequent
inspections.
a) Minimum Inspection Schedule: The permittee shall, at a minimum, make a thorough inspection, in accordance
with the requirements in I.D.6.b below, at least once every 14 calendar days. Also, post -storm event inspections
must be conducted within 24 hours after the end of any precipitation or snowmelt event that causes surface erosion.
Provided the timing is appropriate, the post -storm inspections may be used to fulfill the 14-day routine inspection
requirement. A more frequent inspection schedule than the minimum inspections described may be necessary, to
ensure that BMPs continue to operate as needed to comply with the permit. The following conditional modifications
to this Minimum Inspection Schedule are allowed:
1) Post -Storm Event Inspections at Temporarily Idle Sites — If no construction activities will occur following a
storm event, post -storm event inspections shall be conducted prior to re -commencing construction activities,
but no later than 72 hours following the storm event. The occurrence of any such delayed inspection must be
documented in the inspection record. Routine inspections still must be conducted at least every 14 calendar
days.
2) Inspections at Completed Sites/Areas — For sites or portions of sites that meet the following criteria, but final
stabilization has not been achieved due to a vegetative cover that has not become established, the permittee
shall make a thorough inspection of their stormwater management system at least once every month, and post -
storm event inspections are not required. This reduced inspection schedule is only allowed if.
i) all construction activities that will result in surface ground disturbance are completed;
ii) all activities required for final stabilization, in accordance with the SWMP, have been completed, with
the exception of the application of seed that has not occurred due to seasonal conditions or the necessity
for additional seed application to augment previous efforts; and
iii) the SWMP has been amended to indicate those areas that will be inspected in accordance with the
reduced schedule allowed for in this paragraph.
PART I
Permit - Page 13
Permit No. COR-030000
D. TERMS AND CONDITIONS (cont.)
3) Winter Conditions Inspections Exclusion — Inspections are not required at sites where construction activities
are temporarily halted, snow cover exists over the entire site for an extended period, and melting conditions
posing a risk of surface erosion do not exist. This exception is applicable only during the period where melting
conditions do not exist, and applies to the routine 14-day and monthly inspections, as well as the post -storm -
event inspections. The following information must be documented in the inspection record for use of this
exclusion: dates when snow cover occurred, date when construction activities ceased, and date melting
conditions began. Inspections, as described above, are required at all other times.
When site conditions make the schedule required in this section impractical, the permittee may petition the Division
to grant an alternate inspection schedule.
b) Inspection Requirements
1) Inspection Scope - The construction site perimeter, all disturbed areas, material and/or waste storage areas that
are exposed to precipitation, discharge locations, and locations where vehicles access the site shall be inspected
for evidence of, or the potential for, pollutants leaving the construction site boundaries, entering the stormwater
drainage system, or discharging to state waters. All erosion and sediment control practices identified in the
SWMP shall be evaluated to ensure that they are maintained and operating correctly.
2) Inspection Report/Records - The permittee shall keep a record of inspections. Inspection reports must
identify any incidents of non-compliance with the terms and conditions of this permit. Inspection records must
be retained for three years from expiration or inactivation of permit coverage. At a minimum, the inspection
report must include:
i) The inspection date;
ii) Name(s) and title(s) of personnel making the inspection;
iii) Location(s) of discharges of sediment or other pollutants from the site;
iv) Location(s) of BMPs that need to be maintained;
v) Location(s) of BMPs that failed to operate as designed or proved inadequate for a particular location;
vi) Location(s) where additional BMPs are needed that were not in place at the time of inspection;
vii) Deviations from the minimum inspection schedule as provided in Part I.D.6.a above;
vii) Description of corrective action for items iii, iv, v, and vi, above, dates corrective action(s) taken, and
measures taken to prevent future violations, including requisite changes to the SWMP, as necessary; and
viii) After adequate corrective action(s) has been taken, or where a report does not identify any incidents
requiring corrective action, the report shall contain a signed statement indicating the site is in compliance
with the permit to the best of the signer's knowledge and belief.
c) Required Actions Following Site Inspections — Where site inspections note the need for BMP maintenance
activities, BMPs must be maintained in accordance with the SWMP and Part I.D.7 of the permit. Repair,
replacement, or installation of new BMPs determined necessary during site inspections to address ineffective or
inadequate BMPs must be conducted in accordance with Part I.D.8 of the permit. SWMP updates required as a
result of deficiencies in the SWMP noted during site inspections shall be made in accordance with Part I.D.5.c of the
permit.
BMP Maintenance
All erosion and sediment control practices and other protective measures identified in the SWMP must be maintained in
effective operating condition. Proper selection and installation of BMPs and implementation of comprehensive Inspection
and Maintenance procedures, in accordance with the SWMP, should be adequate to meet this condition. BMPs that are not
adequately maintained in accordance with good engineering, hydrologic and pollution control practices, including removal
of collected sediment outside the acceptable tolerances of the BMPs, are considered to be no longer operating effectively
and must be addressed in accordance with Part I.D.8, below. A specific timeline for implementing maintenance
procedures is not included in this permit because BMP maintenance is expected to be proactive, not responsive.
Observations resulting in BMP maintenance activities can be made during a site inspection, or during general observations
of site conditions.
PART
Permit - Page 14
Permit No. COR-030000
D. TERMS AND CONDITIONS (cont.)
Replacement and Failed BMPs
Adequate site assessment must be performed as part of comprehensive Inspection and Maintenance procedures, to assess
the adequacy of BMPs at the site, and the necessity of changes to those BMPs to ensure continued effective performance.
Where site assessment results in the determination that new or replacement BMPs are necessary, the BMPs must be
installed to ensure on -going implementation of BMPs as per Part I.D.2.
Where BMPs have failed, resulting in noncompliance with Part I.D.2, they must be addressed as soon as possible,
immediately in most cases, to minimize the discharge of pollutants.
When new BMPs are installed or BMPs are replaced, the SWMP must be updated in accordance with Part I.D.5(c).
Reporting
No scheduled reporting requirements are included in this permit; however, the Division reserves the right to request that a
copy of the inspection reports be submitted.
10. SWMP Availability
A copy of the SWMP shall be provided upon request to the Division, EPA, or any local agency in charge of approving
sediment and erosion plans, grading plans or stormwater management plans, and within the time frame specified in the
request. If the SWMP is required to be submitted to any of these entities, it must include a signed certification in
accordance with Part I.F.1 of the permit, certifying that the SWMP is complete and meets all permit requirements.
All SWMPs required under this permit are considered reports that shall be available to the public under Section 308(b) of
the CWA and Section 61.5(4) of the Colorado Discharge Permit System Regulations. The permittee shall make plans
available to members of the public upon request. However, the permittee may claim any portion of a SWMP as
confidential in accordance with 40 CFR Part 2.
11. Total Maximum Daily Load (TMDL)
If a TMDL has been approved for any waterbody into which the permittee discharges, and stormwater discharges
associated with construction activity have been assigned a pollutant -specific Wasteload Allocation (WLA) under the
TMDL, the Division will either:
a) Ensure that the WLA is being implemented properly through alternative local requirements, such as by a municipal
stormwater permit; or
b) Notify the permittee of the WLA, and amend the permittee's certification to add specific BMPs and/or other
requirements, as appropriate. The permittee may be required to do the following:
I ) Under the permittee's SWMP, implement specific management practices based on requirements of the WLA,
and evaluate whether the requirements are being met through implementation of existing stormwater BMPs or
if additional BMPs are necessary. Document the calculations or other evidence that show that the requirements
are expected to be met; and
2) If the evaluation shows that additional or modified BMPs are -necessary, describe the type and schedule for the
BMP additions/revisions.
Discharge monitoring may also be required. The permittee may maintain coverage under the general permit provided they
comply with the applicable requirements outlined above. The Division reserves the right to require individual or alternate
general permit coverage.
PART I
Permit - Page 15
Permit No. COR-030000
E. ADDITIONAL DEFINITIONS
For the purposes of this permit:
1. Best Management Practices (BMPs): schedules of activities, prohibitions of practices, maintenance procedures, and
other management practices to prevent or reduce the pollution of waters of the State. BMPs also include treatment
requirements, operating procedures, pollution prevention, and practices to control site runoff, spillage or leaks, waste
disposal, or drainage from material storage.
2. Dedicated asphalt plants and concrete plants: portable asphalt plants and concrete plants that are located on or adjacent
to a construction site and that provide materials only to that specific construction site.
3. Final stabilization: when all ground surface disturbing activities at the site have been completed, and uniform vegetative
cover has been established with an individual plant density of at least 70 percent of pre -disturbance levels, or equivalent
permanent, physical erosion reduction methods have been employed. For purposes of this permit, establishment of a
vegetative cover capable of providing erosion control equivalent to pre-existing conditions at the site will be considered
final stabilization.
4. Municipal separate storm sewer system: a conveyance or system of conveyances (including: roads with drainage
systems, municipal streets, catch basins, curbs, gutters, ditches, man-made channels, or storm drains), owned or operated
by a State, city, town, county, district, or other public body (created by state law), having jurisdiction over disposal of
sewage, industrial waste, stormwater, or other wastes; designed or used for collecting or conveying stormwater.
5. Operator: the entity that has day-to-day supervision and control of activities occurring at the construction site. This can
be the owner, the developer, the general contractor or the agent of one of these parties, in some circumstances. It is
anticipated that at different phases of a construction project, different types of parties may satisfy the definition of
'operator' and that the permit may be transferred as the roles change.
6. Outfall: a point source at the point where stormwater leaves the construction site and discharges to a receiving water or a
stormwater collection system.
7. Part of a larger common plan of development or sale: a contiguous area where multiple separate and distinct
construction activities may be taking place at different times on different schedules.
8. Point source: any discernible, confined and discrete conveyance from which pollutants are or may be discharged. Point
source discharges of stormwater result from structures which increase the imperviousness of the ground which acts to
collect runoff, with runoff being conveyed along the resulting drainage or grading pattern.
9. Pollutant: dredged spoil, dirt, slurry, solid waste, incinerator residue, sewage, sewage sludge, garbage, trash, chemical
waste, biological nutrient, biological material, radioactive material, heat, wrecked or discarded equipment, rock, sand, or
any industrial, municipal or agricultural waste.
10. Process water: any water which, during manufacturing or processing, comes into contact with or results from the
production of any raw material, intermediate product, finished product, by product or waste product. This definition
includes mine drainage.
It. Receiving Water: any classified stream segment (including tributaries) in the State of Colorado into which stormwater
related to construction activities discharges. This definition includes all water courses, even if they are usually dry, such as
borrow ditches, arroyos, and other unnamed waterways.
12. Significant Materials include, but are not limited to: raw materials; fuels; materials such as solvents, detergents, and
plastic pellets; finished materials such as metallic products; raw materials used in food processing or production; hazardous
substances designated under section 101(14) of CERCLA; any chemical the facility is required to report pursuant to
section 313 of title III of SARA; fertilizers; pesticides; and waste products such as ashes, slag and sludge that have the
potential to be released with stormwater discharge.
13. Stormwater: precipitation -induced surface runoff.

4. Submission of Incorrect or Incomplete Information
Where the permittee failed to submit any relevant facts in a permit application, or submitted incorrect information in a
permit application or report to the Division, or relevant new information becomes available, the permittee shall promptly
submit the relevant application information which was not submitted or any additional information needed to correct any
erroneous information previously submitted.
5. Bypass
a) A bypass, which causes effluent limitations (i.e., requirements to implement BMPs in accordance with Parts I.B.3
and I.D.2 of the permit) to be exceeded is prohibited, and the Division may take enforcement action against a
permittee for such a bypass, unless:
1) Bypass was unavoidable to prevent loss of life, personal injury, or severe property damage;
2) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities (e.g.,
alternative BMPs), retention of untreated wastes, or maintenance during normal periods of equipment
downtime. This condition is not satisfied if the permittee could have installed adequate backup equipment (e.g.,
implemented additional BMPs) to prevent a bypass which occurred during normal periods of equipment
downtime or preventative maintenance; and
3) The permittee submitted notices as required in "Non -Compliance Notification," Part II.A.3.
6. Upsets
J
a) Effect of an Upset: An upset constitutes an affirmative defense to an action brought for noncompliance with permit
limitations and requirements if the requirements of paragraph b of this section are met. (No determination made
during administrative review of claims that noncompliance was caused by upset, and before an action for
noncompliance, is final administrative action subject to judicial review.)
b) Conditions Necessary for a Demonstration of Upset: A permittee who wishes to establish the affirmative defense
of upset shall demonstrate through properly signed contemporaneous operating logs, or other relevant evidence that:
1) An upset occurred and that the permittee can identify the specific cause(s) of the upset;
2) The permitted facility was at the time being properly operated;
3) The permittee submitted notice of the upset as required in Part II.A.3. of this permit (24-hour notice); and
4) The permittee complied with any remedial measures required under 40 CFR Section 122.41(d) of the federal
regulations or Section 61.8(3)(h) of the Colorado Discharge Permit System Regulations.
c) Burden of Proof. In any enforcement proceeding the permittee seeking to establish the occurrence of an upset has
the burden of proof.
Removed Substances
Solids, sludges, or other pollutants removed in the course of treatment or control of discharges shall be properly disposed
of in a manner such as to prevent any pollutant from such materials from entering waters of the State.
8. Minimization of Adverse Impact
The permittee shall take all reasonable steps to minimize any adverse impact to waters of the State resulting from
noncompliance with any terms and conditions specified in this permit, including such accelerated or additional monitoring
as necessary to determine the nature and impact of the noncomplying discharge.

1. INTRODUCTION
The primary purpose of preparing and maintaining a stormwater management plan is to
improve the health and quality of the State's urban waterways. The preparation and
maintenance of the plan will contribute to this objective by facilitating an approach to
stormwater management, establishing a program of actions to be used during construction
activities, and describing stormwater management controls and various Best Management
Practices (BMPs) necessary to reduce erosion, sediment and pollutants in stormwater
discharge.
The appendices of the SWMP contain or have placeholders for documentation necessary
for compliance with the permit:
• Appendix A — The Stormwater Discharge Permit issued by the State of Colorado
(a blank copy of the general permit is included and should be replaced with the
actual permit after receipt).
• Appendix B — The draft General Permit Application (contractor to complete).
• Appendix C — The Site Map showing the site as well as existing and proposed
grading along the trail alignment. The blank map should be copied as many times
as required to prepare a constantly current site map per the permit and notes as to
the locations of all BMPs, etc. The Grading and Erosion Control Plan (in the
construction documents) can be utilized for general guidance for erosion and
sedimentation control, but is only one snapshot in time and will not be pertinent in
all phases of construction. Old copies of the map should be kept as
documentation of past site conditions.
• Appendix D — Contractor's Construction Schedule with notes regarding the BMPs
that are in place during certain phases and when they can be removed.
• Appendix E — Disturbance Tally Sheets that should be updated whenever the area
of disturbance, area of temporary stabilization, or area of permanent stabilization
changes.
• Appendix F — Inspection reports (two sample reports are included — any report
meeting the permit requirements may be used). Inspections are required every 14
days and after every rainfall event (see permit). If any BMPs need repair or
modification after an inspection, the changes need to be made immediately and
the inspection report would be a good place to document that the BMP was fixed,
who repaired it, when the work was started and completed, and certification that it
was completed properly. This strategy will save a separate form and keeps the
information related to the inspection and the repair or modification in the same
location.
• Appendix G — Contractor Forms and Certifications — this section is included as a
place to log training, meetings, etc. Each person that will be involved with
stormwater management needs to understand the SWMP and required procedures
and the Permit Holder's enforcement policy. This Appendix is a place to keep
certifications for the people who have been trained (a statement that they

INSPECTION REPORTS (SAMPLES PROVIDED)
Appendix B: Sample Inspection Report
Instructions
This sample inspection report has been developed as a helpful tool to aid you in completing,your
site inspections. This sample inspection report was created consistent with EPA's Developing
Your Stormwater Pollution Prevention Plan. You can find both the guide and the sample
inspection report (formatted in Microsoft Word) at www.epa.gov/npdes/swpppguide
This inspection report is provided in Microsoft Word format to allow you to easily customize it
for your use and the conditions at your site. You should also customize this form to help you
meet the requirements in your construction general permit related to inspections. If your
permitting authority provides you with an inspection report, please use that form.
For more information on inspections, please see Developing Your Stormwater Pollution Plan
Chapters 6 and 8.
Using the Inspection Report
This, inspection report is designed to be customized according to the BMPs and conditions at
your site. For ease of use, you should take a copy of your site plan and number all of the
stormwater BMPs and areas of your site that will be inspected. A brief description of the BMP
or area should then be listed in the site -specific section of the inspection report. For example,
specific structural BMPs such as construction site entrances, sediment ponds, or specific areas
with silt fence (e.g., silt fence along Main Street; silt fence along slope in NW corner, etc.)
should be numbered and listed. You should also number specific non-structural BMPs or areas
that will be inspected (such as trash areas, material storage areas, temporary sanitary waste areas,
etc).
You can complete the items in the "General Information" section that will remain constant, such
as the project name, NPDES tracking number, and inspector (if you only use one inspector).
Print out multiple copies of this customized inspection report to use during your inspections.
When conducting the inspection, walk the site by`following your site map and numbered
BMPs/areas for inspection. Also note whether the overall site issues have been addressed
(customize this list according to the conditions at your site). Note any required corrective actions
and the date and responsible person for the correction in the Corrective Action Log.
EPA SWPPP Inspection Report, Version 1.1, September 17, 2007
understand the SWMP, enforcement policy, etc.) This can also be where training
meeting notes and attendance sheets can be kept (it is suggested that a portions of
a regular safety meeting include stormwater management training and updates).
An emergency contact list for the contractor and all sub -contractors should be
included in this location and at the construction trailer.
• Appendix H — BMP Details — this includes details of BMPs used with the project.
The BMPs currently included are those related to soil erosion and sedimentation.
Details that may need to be added or modified include confinement/containment
details (dumpsters, tanks, pools, etc,), spill cleanup materials, etc.
• Appendix I — CDPHE Forms- includes blank forms that may be required at some
point while the permit is active. Most importantly, the Inactivity Notice is
included for your use after the site is finally stabilized to effectively end the
permit.
• Appendix J — Stormwater Facts Sheet — this has been included and provides
clarification from the State on questions that may arise during construction. Any
other pertinent reference documents can be kept in this Appendix.
• Appendix K — Soil information — this is the soils map for the site provided by
NRCS.

STATE OF COLORADO
NOTICE OF REASSIGNMENT OF PERMIT COVERAGE
FOR A PORTION OF A PERMITTED AREA
AND GENERAL PERMIT APPLICATION
GENERAL PERMIT FOR
STORMWATER DISCHARGES ASSOCIATED WITH CONSTRUCTION ACTIVITY
This form is to be used when a permittee under the State of Colorado General Permit for Stormwater Discharges Associated
with Construction Activity (the Construction General Permit) no longer has control of a specific portion of a permitted site
through either ownership or contract, and wishes to transfer coverage of that portion of the site to a second party that does
not currently have coverage under the Construction General Permit. If both parties currently have permit coverage,
refer to the Alternative Options section for additional guidance. This application covers Large Construction Sites
(disturbing 5 or more acres) and Small Construction Sites (disturbing at least I but less than 5 acres). Sites that are part of
a larger common plan of development or sale that will disturb at least I acre are also included. A "common plan of
development or sale" is a site where multiple separate and distinct construction activities may be taking place at different
times on different schedules, but still under a single plan. This includes phased projects, projects with multiple filings or
lots, and projects in a contiguous area that may be unrelated but still under the same contract
The following actions will be triggered by completion and submittal of this form:
• The Permit certification in Item ILA will be amended to no longer include the area described in Items 1.13 and I.C.
The current permittee will not receive a revised certification. The corrected information will be placed in the
permit file. If the current permittee requires notification of the Water Quality Control Division's (the Division's)
receipt of this information, it is up to the permittee to request verification of delivery from the carrier (i.e., by
sending certified mail).
• A new permit certification under the General Permit for Stormwater Discharges Associated with Construction
Activity will be issued to the new permittee listed in Part I. A new permit certification and permit materials will be
sent to the attention of the legally responsible person for the new permittee (Item I.i. on the form).
Alternative Options: To transfer the entire permit certification, the Notice of Transfer of Permit Coverage form must be
used instead. Also, if both parties are currently permit holders for portions of the overall project (i.e., at least two permit
certifications are issued for the project and cover both the party wishing to reassign coverage and the party wishing to
accept coverage), and it is not desired that a new permit certification be issued, the permittees may amend their permit
certifications instead of completing this form. For additional instructions, please refer to the guidance on "Amending Your
Permit Certification" in the Stormwater Fact Sheet for Construction, available from the Division's web site at
www.cdphe.state.co.us/wq/PermitsUnit.
Applicant Liability: For the area described for which permit coverage is to be reassigned (Part I.b of the form), permit
coverage and liability will be assigned to the new permit applicant, regardless of ownership or contract, until the
certification is transferred, amended, inactivated, or expired. (Note that even though the new permittee will be liable for
permit compliance for the reassigned area, if the new permittee does not meet the definition of owner or operator as
discussed in the "Who May Apply" section below, the entity(s) that does could be held liable for operating without the
necessary permit coverage.) The permittee may amend their application in writing to cease coverage for a portion of a site
that the permittee no longer either owns or is under contract for. Information on the procedures that must to be used for
such amendments will be supplied with the permit certification.
A more detailed explanation is available in the Stormwater Fact Sheet for Construction, available from the Division's web
site at www.cdphe.state.co.us/wq/PennitsUnit. The Division strongly recommends that entities involved with sites
where multiple owners/operators exist review this information.
Who May Apply For and Maintain Permit Coverage: The applicant must be a legal entity that meets the definition of
either the owner and/or operator of the construction site, in order for this application to legally cover the activities occurring
at the site. The applicant must have day-to-day supervision and control over activities at the site and implementation of the
Stormwater Management Plan (SWMP) discussed in Item I.h of the instructions. Although it is acceptable for the applicant
to meet this requirement through the actions of a contractor, as discussed in the examples below, the applicant remains
liable for violations resulting from the actions of their contractor. Examples of acceptable applicants include:
6/2005/reassign _i_
• Owner or Developer- An owner or developer who is operating as the site manager or otherwise has supervision and
control over the site, either directly or through contract with an entity such as those listed below.
• General Contractor or Subcontractor - A contractor with contractual responsibility and operational control (including
SWMP implementation) to address the impacts construction activities may have on stormwater quality.
• Other Delegated Agents/Contractors - Other agents, such as a consultant acting as construction manager under contract
with the owner or developer, with contractual responsibility and operational control to address the impacts construction
activities may have on stormwater quality (including SWMP implementation).
An entity engaged in construction activities may be held liable for operating without the necessary permit coverage if a site
does not have a permit certification in place that is issued to either an owner and/or operator. For example, if a site, or
portion of a site, is sold or contractors change, so that the site's permit certification is then held by a permittee that is no
longer either the owner or operator (such as the previous owner or contractor), that permit certification will no longer cover
the new operator's activities, and a new certification must be issued, or the current certification transferred.
A separate permit certification is not needed for subcontractors, such as utility service line installers, whose activities result
in earth disturbance, but where the permittee or their contractor is identified as having the operational control to address the
impacts .their activities may have on stormwater quality.
Stormwater Management Plan (SWMP): Both the current permittee and the new applicant must develop and maintain
SWMPs that accurately reflect the activities and BMPs for the areas for which they will have permit coverage. The current
permittee must already have a SWMP in place as required by their permit coverage, but must revise this plan to account for
the changes in their covered area and activities. As discussed in Item I.h. of the instructions, the new applicant must also
develop a SWMP for their covered area, prior to submittal of this form. Although the new applicant may utilize the current
permittee's SWMP, if available, in development of their own SWMP, it must be modified and maintained to accurately
reflect the new applicant's activities. Appendix A of the General Permit Application and Stormwater Management Plan
Guidance for Stormwater Discharges Associated with Construction Activity (available from the Division's web site at
www.cdphe.state.co.us/wq/PermitsUnit) contains the requirements for the SWMP. Failure by either entity to maintain a
SWMP in accordance with this guidance is a violation of the permit. Additional guidance for multi owner/operator
development is also available in the Stormwater Fact Sheet for Construction, also available from the Division's web site.
Application Due Dates: At least ten days prior to the requested effective date for the coverage reassignment, the owner or
operators of the construction activities shall submit this form to the Water Quality Control Division (the "Division"). This
form may be reproduced, and is also available from the Division's web site at www.cdphe.state.co.us/wq/PermitsUnit.
Permit Fee: The new permittee does not send any payment with this form. They will be billed once they are covered
under a permit. Current permit fees can be obtained from the Division's web site at www.cdphe.state.co.us/wq/PermitsUnit.
Application Completeness: All items of the form must be completed accurately and in their entirety or the application will
be deemed incomplete, and processing of the form will not begin until all information is received. (Do not include a copy
of the Stormwater Management Plans for either the current or new permittee, unless requested by the Division.) One
original copy of the completed form (no faxes or e-mails), signed by both the new permittee and the current permittee, shall
be submitted, only to:

REASSIGNMENT FORM
INSTRUCTIONS
PART I - (To be completed by the New permit applicant.)
Part I of the application is to be filled out by the new permit applicant who will be assuming permitting liability for the reassigned
portion of the original applicant's site. The effective date when the area addressed in the form will be reassigned must be
provided at the beginning of Part I. The effective date must be at least ten days following the receipt of this form by the Division.
It will be the effective date of the new permit certification issued to the new applicant in Part I.
Item I.a.: Provide the name and address of the new permit applicant, including the company name, local contact, phone number,
and mailing address. Indicate whether the applicant is the owner, developer or contractor.
Item I.b.:. Provide the street address of the site that will be covered under the new certification and removed from the current
certification. If an exact address is not available you may use an approximate address, the nearest intersection or boundary streets
including directional identifiers (e.g., "S. of Park St. between 5th Av and 10th Av.", or "W. side of C.R. 21, 3.25 miles N. of Hwy
10") or other identifying information. For the approximate center point of the property, the longitude/latitude, to the nearest 15
seconds, must be included. The latitude and longitude must be provided as either degrees, minutes, and seconds, or in decimal
degrees with three decimal places. This information may be obtained from a variety of sources, including:
• Surveyors or engineers for the project should have, or be able calculate, this information.
• EPA maintains a web -based siting tool as part of their Toxic Release Inventory program that uses interactive maps and aerial
photography to help users get latitude and longitude. The'siting tool can be accessed at:
www.epa.gov/tri/report/siting_tooUindex.htm
• U.S. Geological Survey topographical map, available at area map stores.
• Using a Global Positioning System (GPS) unit to obtain a direct reading.
Item Le.: One of these two items must be provided:
• Legal Description of the entire site covered by the application that must include subdivision(s), block(s), and lot(s) (providing
the metes and bounds or just the township/section/range, is not adequate). This information should be available for subdivided
properties from documents submitted to or maintained by the city or county, such as the subdivision plat or deed. If this
information is not available, a map must be submitted. — or —
• Site Map that defines the boundaries of the site being applied for. The level of detail that must be provided will depend on
the nature of the project and must be adequate so that it can be determined during a field audit what construction activities are
covered under the issued certification. For typical developments within a specific surveyed property, a map clearly showing
the property boundaries should be obtainable. For projects located in areas with adjacent construction areas that will not be
covered by the application (such as multi -lot developments with multiple owners/operators), this detail is essential. However,
for projects such as road or utility projects, where providing this detail may not be feasible or necessary to distinguish the
project from adjacent activities, a less detailed map showing the approximate area is adequate. Maps must have a minimum
scale of 1:24000 (the scale of a USGS 7.5 minute map). Maps must be folded to 8% x 11 inches. Do not submit grading
plans or other blueprints as the site map.
Item I.d.: Provide both the total area of the construction site that will be covered under the new certification, and the area that
will undergo disturbance, in acres. Note: aside from clearing, grading and excavation activities, disturbed areas also include
areas receiving overburden (e.g., stockpiles), demolition areas, and areas with. heavy equipment/vehicle traffic and storage
that disturb existing vegetative cover.
Item I.e.: Either check the appropriate box or boxes, or if the given descriptions do not fit the project, provide a brief description
that indicates the general nature of the construction activities for which permit coverage is being requested. A more detailed
description of the project must be included in the Stormwater Management Plan (see Item I.i.).
Item I.f.: Provide the current estimated completion date for the construction project to be covered under the new certification. In
terms of permit coverage, the completion date is when the site is finally stabilized. This means that all disturbed areas have been
either built on, paved, or a uniform vegetative cover has been established. Permit coverage must be maintained until that
time. If permit coverage is still required once your part is completed, the permit must be transferred to a new responsible entity.

Item I.g.: Identify the receiving water. Receiving waters are any waters of the State of Colorado. These include any and all
surface waters that are contained in or flow in or through the State of Colorado (except for water withdrawn for use until use and
treatment have been completed). This definition includes all water courses, even if they are usually dry. If stormwater from the
construction site enters a ditch or storm sewer system, identify that system and indicate the ultimate receiving water for the ditch
or storm sewer. Note: a stormwater discharge permit does not allow a discharge into a ditch or municipal storm sewer system
without the approval of the owner/operator of that system if such approval is otherwise needed.
Item I.h.: The certification of completion of a Stormwater Management Plan (SWMP) must be signed by the applicant or their
authorized agent. Appendix A of the General Permit Application and Stormwater Management Plan Guidance for Stormwater
Discharges Associated with Construction Activity (available form www.cdphe.state.co.us/wg/PennitsUnit) contains the
requirements for the SWMP during the period of construction (as listed in the general permit). Submittal of the SWMP is not
required, however it must be developed and implemented and kept at the construction site. The Division reserves the right to
request the SWMP at any time.
Item I.i.: The applicant must be either the owner and/or operator of the construction site. Refer to page i of the instructions for
additional information. The application must be signed to be considered complete. In all cases, it shall be signed as follows:
a) In the case of corporations, by a principal executive officer of at least the level of vice-president or his or her duly authorized
representative, if such representative is responsible for the overall operation of the facility from which the discharge
described in the application originates.
b) In the case of a partnership, by a general partner.
c) In the case of a sole proprietorship, by the proprietor.
d) In the case of a municipal, state, or other public facility, by either a principal executive officer, ranking elected official, or
other duly authorized employee.
This certification includes an acknowledgment that the applicant understands that the permit coverage, and therefore the
applicant's liability, will be for the entirety of the portion of the construction project described and applied for, until such
time as the application is amended or the certification is transferred, inactivated, or expired.
PART II - (To be completed by the Current permittee.)
Part H of the application, starting on page 3 of the form, is to be completed by the current permittee. The information provided
in Part II.b should be revised from the original application to take into account the changes in the site based on reassignment of
the applied -for area. Refer to the instructions for I.c and I.d above for information on providing location and construction activity
description information.
6/2005/reassign _iv_
The construction will impact approximately 6.4 acres of the 6.4 acre site. Approximately
2.8 acres of land will undergo grading and trail construction (concrete pour).
Construction staging will take place east of the existing edge of pavement at Keenland
Drive. All runoff will follow existing flow paths.
The site has been mapped by the NRCS and the information is included in Appendix K.
There are multiple soils on site including Fort Collins loam (HSG B), Heldt clay loam
(HSG C), Kim loam (HSG B), Longmont clay loam (HSG C), Nunn clay loam (HSG B),
and Stoneham loam (HSG B).
The entire site is currently established with existing vegetation. The existing vegetation
consists of natural grasses and shrubs with approximately 95% coverage.
No known sources of pollution currently exist on this site. Potential pollutant sources
brought onto the site during construction will be discussed (along with spill prevention)
below. There are no anticipated non-stormwater components of discharge with this
project.
The receiving waters for this area are Mail Creek Ditch for the northern quarter of the site
and Fossil Creek for the remainder of the site. Ultimately, all runoff along the trail drains
to Fossil Creek Reservoir.
No portion of the site is in a FEMA floodplain. A 404 Permit from the Corps of
Engineers has not been required. No other known permits related to stormwater are
known.

STATE OF COLORADO
NOTICE OF AMENDMENT OF PERMIT COVERAGE
Terminating coverage fora Portion of a permitted area
GENERAL PERMIT FOR
STORMWATER DISCHARGES ASSOCIATED WITH CONSTRUCTION ACTIVITY
This form is to be used to amend a permit certification under Colorado's Stormwater Construction
Permit, to terminate permit coverage when both of the following conditions have been met:
1. The area must no longer be under the operational control (via ownership or contract) of the
permittee. AND
2. The area must be Finally Stabilized. An area is Finally Stabilized when all ground surface
disturbing activities at the site have been completed, and all disturbed areas have been either built
on, paved or equivalently hard -armored, or a uniform vegetative cover has been established with an
individual plant density of at least 70 percent of pre -disturbance levels.
Upon acceptance of this notice by the Water Quality Control Division (the Division), the permit
certification will be automatically amended to exclude the specific portion described in the notice. The
current permittee will not receive a revised certification. The corrected information will be placed
in the permit file. In order to receive notification of the Division's receipt of this information, it is up
to the permittee to request verification of delivery from the carrier (i.e., by sending certified mail).
Conditions When This Form Can NOT Be Used: Below are some common scenarios where a
permittee may need to use a different form or process. For additional guidance on administrative
requirements and options for the Stormwater Construction Permit, refer to the Stormwater Construction
Fact Sheet available at coloradowaterpermits.com The Division strongly recommends that entities
involved with sites where multiple owners/operators exist review this information.
A. The Permittee Still Has Operational Control over the Area
The permit can only be amended to terminate coverage for sites that are no longer under the
operational control of the permittee. If the permittee still has operational control:
What to do instead: Revise your Stormwater Management Plan (SWMP) to address the conditions
and the BMPs used in the stabilized area. BMPs may still be needed depending on site -specific
conditions, such as stormwater run-on or construction traffic from areas of active construction.
Monthly inspections are still required in accordance with Part I.D.6 of the permit, but only need to
focus on identifying pollutant sources (e.g., erosion, material storage, etc.) and BMPs.
B. The Area Has Not Been Finally Stabilized
This form is only for terminating an area that has been finally stabilized. If the area has not been
finally stabilized:
What to do instead: The permittee must either maintain permit coverage, or can reassign permit
coverage to another entity that owns or has operational control over that area. The Division's
Notice of Reassignment of Permit Coverage form should be used. The form is available at
coloradowaterpermits.com
C. The Entire Permitted Area Has Been Finally Stabilized
This form is intended for use when the conditions in 1 AND 2 above have been met, and the
permittee wishes to terminate permit coverage for only part of the site. Submittal of this form will
only result in the termination of coverage for a portion of a permitted site, and does not inactivate
the permit certification.
What to do instead: Use the Inactivation Form for construction activities, available at
co loradowaterpermits. com
9/N/coverageamend _ -
Stormwater Management Plan (SWMP): The permittee must maintain a SWMP that accurately
reflects the activities and BMPs for the areas for which they will have permit coverage. Therefore, the
SWMP must be updated to reflect the changes described in this form. Appendix A of the General
Permit Application and SWMP Guidance for Stormwater Discharges Associated with Construction
Activity (available from the Division's web site at coloradowaterpermits. com) contains the
requirements for the SWMP.
Failure by the permittee to maintain a SWMP in accordance with this guidance is a violation of the
permit. Additional guidance for multi owner/operator development is also available in the Stormwater
Fact Sheet for Construction, available from the Division's web site.
Notice Due Dates: At least ten days prior to the requested effective date for permit coverage to end,
the permittee shall submit this form to the Division. This form may be reproduced, and is also
available from the Division's web site at coloradowaterperm its. com.
Permit Fee: There are no new permit fees associated with amending the construction permit
certification.
Application Completeness: All items on the form must be completed accurately and in their entirety
or the notice will be deemed incomplete, and processing of the form will not begin until all information
is received. A map of the revised area must be included that clearly indicates the area with continued
coverage under the permit certification, and the area excluded. (Do not include a copy of the SWMP.)
One original copy of the completed form (no faxes or e-mails), signed by the current permittee, shall
be submitted, only to:

INSTRUCTIONS
Site Map: A Site Map must be provided. The map must clearly define the boundaries of the site to be
excluded from permit coverage, and the area of the site with continued coverage under the permit
certification. The level of detail that must be provided will depend on the nature of the project, and
must be adequate to determine during a field audit what construction activities are still covered under
the issued certification.
For typical developments within a specific surveyed property, a map clearly showing the property
boundaries should be obtainable. For projects located in areas with adjacent construction areas that
will not be covered by the application (such as multi -lot developments with multiple owners/operators),
this detail is essential. However, for projects such as road or utility projects, where providing this detail
may not be feasible or necessary to distinguish the project from adjacent activities, a less detailed map
showing the approximate area is adequate. Maps should NOT exceed 8 `/z x 17 inches. Do not submit
grading plans or other blueprints as the site map.

Look for this symbol throughout this guide for brief summaries of the most important information you need to
• know about stormwater permitting for construction activities. Then read further if you want more details.
In 1992, the State of Colorado stormwater regulation went into effect to control municipal and industrial stormwater
discharges, based on EPA regulations. The regulation is meant to reduce the amount of pollutants entering streams,
rivers, lakes, and wetlands as a result of runoff from residential, commercial and industrial areas. The State regulation
(5 CCR 1002-61) covers discharges from specific types of industries including construction sites, and storm sewer
systems for certain municipalities. In Colorado, the program is under the Colorado Department of Public Health &
Environment, Water Quality Control Division (the Division). The Colorado program is referred to as the Colorado
Discharge Permit System (CDPS), and regulated stormwater discharges from construction activities are covered under
the CDPS General Permit for Stormwater Discharges Associated with Construction Activities (the Stormwater
Construction Permit).
Construction activities produce many different kinds of pollutants which may cause stormwater contamination
problems. The main pollutant of concern at construction sites is sediment.. Grading activities remove grass, rocks,
pavement and other protective ground covers, resulting in the exposure of underlying soil to the elements. The soil is
then easily picked up by wind and/or washed away by rain or snowmelt. Sediment runoff rates from construction sites
are typically 10 to 20 times greater than those from agricultural lands, and 1,000 to 2,000 times greater than those from
forest lands. During a short period of time, construction activity can contribute more sediment to streams than would
normally be deposited over several decades, causing physical, chemical, and biological harm to our State's waters. The
added sediment chokes the river channel and covers the areas where fish spawn and plants grow.
Page 1 of 10 Revised 7/07
Water Quality Control Division — Stormwater Program www.cdphe.state.co.us/wq/permitsunit
Excess sediment can cause a number of other problems for waterbodies, such as increased difficulty in filtering drinking
water, and clouding the waters, which can kill plants growing in the river and suffocate fish. A number of pollutants,
such as nutrients, are absorbed onto sediment particles and also are a source of pollution associated with sediment
discharged from construction sites.
In addition, construction activities often require the use of toxic or hazardous materials such as fuel, fertilizers,
pesticides and herbicides, and building materials such as asphalt, sealants and concrete, which may also pollute
stormwater. These materials can be harmful to humans, plants and aquatic life.
This Fact Sheet provides general guidance for compliance with the CDPS permitting requirements for stormwater
discharges from construction activities. The Division reserves the right to interpret the permitting requirements on a
case -by -case basis, as necessary.
B. OBTAINING REGULATORY COVERAGE FOR CONSTRUCTION SITES
You must obtain permit coverage (or an R-Factor waiver) to discharge stormwater from any construction
*� activity that disturbs at least 1 acre of land (or is part of a larger common plan of development or sale that will
disturb at least 1 acre).
The owner or operator must apply for coverage under the Stormwater Construction Permit at least 10 days
prior to the start of construction activities. The application is available from the Division's web page.
1) Do you need to obtain coverage under the Stormwater Construction Permit?
Construction Sites that disturb one acre or greater, or are part of a larger common plan of development disturbing
one acre or greater, are covered under Colorado's stormwater permitting requirements. Generally, permit coverage
is required, as discussed in Part B. La, below. However, additional options may exist if your project or plan of
development will disturb less than 5 acres (Small Construction Site), as discussed in Part B. Lb, below. If permit
coverage is required, or a waiver applied for, it must be maintained until the site is finally stabilized.
Is it part of a larger common plan of development or sale?
"A common plan of development or sale" is a site where multiple separate and distinct construction activities may be
taking place at different times on different schedules. Examples include: 1) phased projects and -projects with multiple
filings or lots, even if the separate phases or filings/lots will be constructed under separate contracts or by separate
owners (e.g., a project where developed lots are sold to separate builders); 2) a development plan that may be phased
over multiple years, but is still under a consistent plan for long-term development; and 3) projects in a contiguous area
that may be unrelated but still under the same contract, such as construction of a building extension and a new parking
lot at the same facility. If the project is part of a common plan of development or sale, the disturbed area of the
entire plan must be used in determining permit requirements.
Disturbance associated with utilities, pipelines, or roads that are constructed for the purpose of serving a facility, are
considered together with that facility to be part of a common plan of development. However, adjacent construction of trunk
lines or roads that are part of a regional network and not directly associated with the facility construction, are not usually
considered to be part of the common plan for that facility. Note that permit coverage or an R-Factor waiver is still required
for each individual project (facility or adjacent construction activity) that disturbs one or more acres
What is the total estimated area of disturbance?
The area of disturbance is the total area at the site where any construction activity is expected to result in disturbance of
the ground surface. This includes any activity that could increase the rate of erosion, including, but not limited to,
clearing, grading, excavation, and demolition activities, installation of new or improved haul roads and access roads,
staging areas, heavy vehicle traffic areas, stockpiling of fill materials, and borrow areas. Construction does not include
routine maintenance to maintain original line and grade, hydraulic capacity, or original purpose of the facility.
"Finally Stabilized" means that all ground surface disturbing activities at the site have been completed, and all
disturbed areas have been either built on, paved, or a uniform vegetative cover has been established with an individual
plant density of at least 70 percent of pre -disturbance levels, or equivalent permanent, physical erosion reduction
methods have been employed. Re -seeding alone does not qualify.
Page 2 of 10 Revised 7/07
Water Quality Control Division — Stormwater Program www.cdphe.state.co.us/wq/permitsunit
a) Applying for a permit
Application for coverage under the Stormwater Construction Permit must be made at least 10 days prior to the
start of construction activities, unless the site is a Small Construction Site that qualifies for an alternative option
discussed in B. Lb, below. An application, which includes guidance on developing a Stormwater Management
Plan (SWMP), is available from the Division. The SWMP must be completed prior to application. See Section
C, "Permit Requirements," for further information. If your application is complete, it will be processed and your
permit certification mailed to you.
The Stormwater Construction Permit certification must be inactivated once the site has been finally stabilized, in
order to end permit coverage and billing. An inactivation form is supplied with the permit certification.
b) Additional Options for Small Construction Sites (at least 1 acre, but less than 5 acres of disturbance)
The following options may apply to Small Construction Sites that disturb less than 5 acres, and are not part of a
larger common plan of development exceeding 5 acres.. (Regardless of which option applies at the State level,
all local requirements must still be met as discussed in Section D, below.)
The options discussed under Parts b.i and b.ii below are not available for Large Construction Sites.
i) Obtain coverage under a State -designated Qualifying Local Program
(Available for Small Construction Sites only)
The Division may designate a local municipality's stormwater quality control program as a Qualifying Local
Program. This means that the local program's requirements are at least as stringent as the State permit. In
this case, it is not required for the owner or operator to apply for permit coverage under the Stormwater
Construction Permit. The local municipality will be responsible for notifying you that you do not need to
apply for State coverage, if this is an option. You can also view a list of the few municipalities with
Qualifying Local Programs at the Division's web page (see first page for web address).
The local program must have been formally designated by the Division to qualify. Most municipalities have
some type of local program and may require permits and fees. However, simply having a local program in
place does not necessarily mean that it is a qualifying program and that the Division's Stormwater
Construction Permit application is not required.
ii) Apply for coverage under the R-Factor Waiver
(Available for Small Construction Sites only)
The R-Factor waiver allows a site owner or operator to apply for a waiver from coverage under the
Division's Stormwater Construction Permit, if the R-Factor, calculated using the State -approved method, is
less than 5 during the period of construction. The R-Factor is a way to measure erosion potential based on
the length of the project and time of year. An application with instructions for using the State -approved
method is available from the Division's web page (see first page for web address).
In general, the only projects that will qualify for the waiver are projects that are completely stabilized
within a month or two after the start of construction. That means that projects relying on seeding for
revegetation will usually not qualify for the waiver, because the vegetation must be established before the
site is considered stabilized. During the spring and summer months, when Colorado experiences the bulk of
its rainfall, many projects will not qualify at all for the waiver. In addition, the Division will not grant
waivers for construction sites located in areas where snow cover exists at, or up gradient of, the site for
extended periods of time, if the construction site will potentially remain active and unstabilized during
spring runoff.
This waiver does not relieve the operator or owner from complying with the requirements of local agencies,
such as meeting local stormwater quality requirements, including those required by a Qualifying Local
Program as discussed in Section B.l.b.i, above.
Page 3 of 10 Revised 7/07
professionals shall react to any stormwater issue as directed in their training, per the
SWMP and in accordance with the Permit. Any and all occurrences or observations that
affect the SWMP or Permit shall be reported to the SWMP Administrator.
Water Quality Control Division Stormwater Program www.cdphe.state.co.us/wq/permitsunit
2) Who may apply for permit coverage?
The Permit applicant must be a legal entity that meets the definition of the owner and/or operator of the construction
site, in order for this application to legally cover the activities occurring at the site. The applicant must have day-to-
day supervision and control over activities at the site and implementation of the SWMP. Although it is acceptable
for the applicant to meet this requirement through the actions of a contractor, as discussed in the examples below,
the applicant remains liable for violations resulting from the actions of their contractor and/or subcontractors.
Examples of acceptable applicants include:
• Owner or Developer - An owner or developer who is operating as the site manager or otherwise has supervision
and control over the site, either directly or through a contract with an entity such as those listed below.
• General Contractor or Subcontractor - A contractor with contractual responsibility and operational control
(including SWMP implementation) to address the impacts construction activities may have on stormwater
quality.
• Other Designated Agents/Contractors - Other agents, such as a consultant acting as construction manager
under contract with the owner or developer, with contractual responsibility and operational control (including
SWMP implementation) to address the impacts construction activities may have on stormwater quality.
An entity conducting construction activities at a site may be held liable for operating without the necessary permit
coverage if the site does not have a permit certification in place that is issued to an owner and/or operator. For
example, if a site (or portion of a site) is sold or the contractor conducting construction activities changes, the site's
permit certification may end up being held by a permittee (e.g., the previous owner or contractor) who is no longer
the current owner and/or operator. In this case, the existing permit certification will no longer cover the new
operator's activities, and a new certification must be issued, or the current certification transferred. See Section F,
below, for additional guidance on scenarios with multiple owners and/or operators.
Utilities, Other Subcontractors, etc.: A separate permit certification is not needed for subcontractors, such as
utility service line installers, where the permittee or their contractor is identified as having the operational control to
address any impacts the subcontractor's activities may have on stormwater quality. Although separate permit
coverage may not be needed in some cases, these entities are not exempt from the stormwater regulations for all of
their projects and may still be held liable if their activities result in the discharge of pollutants.
Leases: When dealing with leased land or facilities, the lessee shall be considered the "owner" for the purposes of
stormwater permitting if they are responsible for the activities occurring at the site.
C. PERMIT REQUIREMENTS
The primary requirement of the Stormwater Construction Permit is the development and implementation
• of a Stormwater Management Plan (SWMP). The permit application includes guidance that must be
followed for development and implementation of the SWMP. Permit requirements are the same for both
Small and Large Construction Sites.
The Stormwater Construction Permit requires dischargers to control and eliminate the sources of pollutants in
stormwater through the development and implementation of a Stormwater Management Plan (SWMP). The purpose of
a SWMP is to identify possible pollutant sources that may contribute pollutants to stormwater, and identify Best
Management Practices (BMPs) that, when implemented, will reduce or eliminate any possible water quality impacts.
For construction activities, the most common pollutant source is sediment. Other pollutant sources include fuels,
fueling practices and chemicals/materials stored on site, concrete washout, etc. BMPs encompass a wide range of
practices, both structural and non-structural in nature, and may include silt fence, sediment ponds, vehicle tracking
controls, good housekeeping, inspection and maintenance schedules, training, etc.
The SWMP is not submitted with the permit application unless requested. An up-to-date copy of the SWMP must be
kept on site, for use by the operator, and so that Division, EPA, or local inspectors can review it during an inspection.
If an office location is not available at the site, the SWMP must be managed so that it is available at the site when
construction activities are occurring (e.g., by keeping the SWMP in a superintendent's vehicle.)
Further information concerning the contents of the SWMP can be found in Appendix A of the application, "Preparing a
Stormwater Management Plan." This document and others can be obtained from the Division's web site or by
contacting the Division (see first page for address information).

D. LOCAL STORMWATER REQUIREMENTS FOR CONSTRUCTION
Where local requirements exist for stormwater management, an owner/operator must comply with both
J�. the Division's and the local agency's requirements.
In addition to the requirement to obtain and comply with the Division's Stormwater Construction Permit, it is possible
that additional government agencies (i.e., cities, counties, and special districts) may impose local requirements to
control the discharge of pollutants from construction activities. An owner or operator of a construction activity must
comply with the Stormwater Construction Permit requirements discussed in this Fact Sheet, even if they are also
covered by a local program's requirements. (However, in the case of a Qualifying Local Program, as discussed in
Section B.l.b.ii, some administrative requirements for the Stormwater Construction Permit may be simplified.)
Likewise, the Stormwater Construction Permit does not pre-empt or supersede the authority of local agencies to
prohibit, restrict, or control discharges of stormwater. Where a local program places additional restrictions on
stormwater management at a construction site within its jurisdiction, the owner/operator must comply with those stricter
requirements in addition to the Division's.permitting requirements. For example, although the Division allows several
options for permitting at multiple owner/operator sites, a local authority may restrict these options and require specific
procedures to be followed for who maintains permit coverage and authority for stormwater discharges.
MS4 Permits
Many cities, counties, and special districts are covered by a Municipal Separate Storm Sewer System (MS4) .
permit. These permits require the governmental entity to implement various programs to improve stormwater
quality in their jurisdiction. Included in these permits is the requirement to implement a program to manage the
discharge of pollutants from construction sites within their jurisdiction. Therefore, if a construction site located
within the jurisdiction of one of these government entities does not properly manage stormwater at that site, the
government entity may be in violation of their permit in addition to the construction site owner and operator.
E. AMENDING YOUR PERMIT CERTIFICATION
JNThis section is only applicable if the limited information on the construction project submitted in the two-
page application form changes. In such case, it may be necessary to provide the Division with revised
information.
If the information provided by the permittee in their two -page application form is no longer accurate, the permittee
must provide the revised information to the Division. This includes such items as the planned total disturbed acreage,
and the project legal description or map originally submitted with the application. (Note: it is not necessary to revise the
anticipated final stabilization date, since the information provided was only an estimate.) To revise this information,
provide a letter to the Division's Stormwater Program (see the contact information on page 1) that includes the revised
information. The Division will not respond to this letter, so you are advised to obtain delivery confirmation from your
postal service to confirm receipt.
When the Stormwater Management Plan is revised, as required by the Stormwater Construction Permit, it is not
necessary to notify the Water Quality Control Division. When BMPs or other site details discussed in the SWMP are
modified, the SWMP must be updated to accurately reflect the actual field conditions: Examples include, but are not
limited to, removal of BMPs, addition of BMPs, modification of BMP design specifications, and changes in items
included in the site map and/or description. However,this information is not submitted to the Division, unless
requested.
F. ENDING YOUR PERMIT COVERAGE
13 A Stormwater Construction Permit certification remains active until inactivated, or transferred or
reassianed to a new responsible party. Forms for inactivation, transfer or reassignment of a permit
certification can be obtained from the Division's web site or by contacting the Division (see first page for
address information).
Page 5 of 10 Revised 7/07
Water Quality Control Division — Stormwater Program www.cdphe.state.co.us/wq/permitsunit
1) Inactivation notice
Permit coverage for a site that has been finally stabilized in accordance with the SWMP (see definition in Section
B.1, above), may be inactivated by submitting a completed Inactivation Notice form. This form contains a
certification statement that must be signed in accordance with the General Requirements of the permit.
Also, the permittee may inactivate permit coverage at sites where all areas have been removed from their permit
coverage, by one or more of the methods below:
• reassignment of permit coverage (see Section F.3);
• sale to homeowner(s) (see Section H); and/or
amendment by the permittee, as discussed in Section E, above for areas where permit coverage has been
obtained by a new operator (see Part G.1, below) or the area is returned to agricultural use (see the Division's
Oil and Gas Construction Fact Sheet).
In these cases the permittee would no longer have any land covered under their permit certification, and therefore
there would be no areas remaining to finally stabilize. Submittal of an Inactivation Notice is still required and must
discuss how the above conditions have been met.
2) Transfer of permit
Permit coverage for a construction site may be transferred to a new entity when responsibility for stormwater
discharges at the site changes from the permittee to the new entity. To transfer permit coverage, the permittee must
submit a completed Notice of Transfer and Acceptance of Terms form that is signed in accordance with the
General Requirements of the permit.
If the new entity will not complete their portion of the transfer form, the permit certification may be inactivated if
the permittee has no legal responsibility for the construction activities at the site, requests inactivation in written
correspondence to the Division, and submits a completed Inactivation Notice form.
3) Reassignment of permit
Permit coverage for a specific portion of a permitted site may be reassigned to a new entity when a permittee no
longer has control of that portion of the site, and wishes to transfer coverage of that portion to a second party. To
reassign permit coverage for a specific portion of a permitted site, the permittee must submit a completed Notice of
Reassignment of Permit Coverage form that is signed in accordance with the General Requirements of the permit.
If the new entity will not complete their portion of the reassignment form, the specific portion of the site may be
removed from permit coverage if the permittee has no legal responsibility for the construction activities at the
portion of the site, and a written request (including contact information for the new entity) is submitted to the
Division.
G. PERMITTING FOR DEVELOPMENTS WITH MULTIPLE OWNERS AND/OR OPERATORS
. For situations where multiple entities meet the definition of owners and/or operators for different
*� portions of a development (e.g., a single development with multiple lots being owned and operated by
separate entities), extra care must be taken to ensure that proper permit coverage is maintained and that
stormwater management practices are correctly documented and implemented.
Local stormwater quality programs may have differing requirements for who must maintain permit coverage, and what
actions must occur when permitted areas and/or activities change. Construction site owners and operators must ensure
that their actions do not result in violations of local program requirements. Refer to Section D for additional
information.
1) Permit Coverage for Multiple Owner/Operator Development
When a portion of a permitted site is sold to a new owner, a permit certification must be in place that is
• held by an entity meeting the definition of owner and/or operator of the sold area (see the discussion in
Section B.2, above). This may be accomplished in one of the following ways:
Page 6 of 10 Revised 7/07
Water Quality Control Division — Stormwater Program www.cdphe.state.co.us/wq/permitsunit
a) Coverage Under the Existing Certification — Activities at the sold area may continue to be covered under an
existing permit certification for the project if the current permittee meets the definition of operator for the sold
area. To meet the definition of operator, the current permittee must have contractual responsibility and
operational control to address the impacts that construction activities at the sold area may have on stormwater
runoff (including implementation of the SWMP for the sold area). Therefore, a legally binding agreement must
exist assigning this responsibility to the current permit holder on behalf of the new owner and/or operator for the
sold area. It is not necessary to notify the Division in such case. However, documentation of the agreement
must be available upon request, and the SWMP must be maintained to include all activities covered by the
Stormwater Construction Permit.
Example: Developer Dan sells a lot to Builder Bob. Developer Dan is currently covered by a permit
certification that covers a larger area, which includes the sold lot. Developer Dan and Builder Bob may enter
into a contract that assigns the responsibility for permit coverage and stormwater management to Developer Dan
for Builder Bob's lot. Developer Dan is also responsible for making sure his SWMP includes the activities on
the sold lot. Developer Dan's permit certification will continue to cover construction activities on Builder Bob's
lot.
b) New Certification Issued — Reassignment — A new permit certification may be issued to the new owner and/or
operator of the sold area. The existing permittee and the new owner and/or operator must complete the
Reassignment Form (available from the Division's web page, see page 1) to remove the sold area from the
existing permit certification and cover it under a certification issued to the owner and/or operator of the sold
area. Both entities must have SWMPs in place that accurately reflect their current covered areas and activities.
Example: Developer Dan sells a lot to Builder Bob. Developer Dan is currently covered by a permit
certification that covers a larger area, which includes the sold lot. For this example, Developer Dan and Builder
Bob must jointly submit the Reassignment Form. Builder Bob will be issued a new permit certification for his
lot and the lot will be removed from Developer Dan's permit coverage. Prior to submittal of the Reassignment
Form, Developer Dan must revise his SWMP to reflect the changes in his covered area and activities, and
Builder Bob must develop his own SWMP to cover the area and activities he will obtain coverage for.
c) Amend Existing Permit Certifications — In some cases, both parties (the original owner/operator and the new
owner/operator of an area undergoing transfer of ownership or operation) will already both be permit holders for
their portions of the overall project (i.e., at least two permit certifications are issued for the project and cover
both the party wishing to reassign coverage and the party wishing to accept coverage). When an additional area
is transferred between the two parties, the permittees may simply amend their permit certifications instead of
completing the Reassignment Form. Both parties must separately complete the procedures discussed in Section
E to amend their permit coverage, removing the applicable area(s) from the original owner/operator's permit
coverage, and adding the area(s) to the new owner/operator's permit coverage. The requests must cite both
permit certification numbers. (Note: this request may be submitted jointly if it is signed by both entities.)
This option will likely be used in cases where a developer and an owner have already submitted a Reassignment
Form, as discussed in Part b, above, where an initial transfer of lots has occurred, and then additional lots are
transferred at a later date. Both entities must have SWMPs in place that accurately reflect their current covered
areas and activities.
Example: Developer Dan sells a lot to Builder Bob. Developer Dan is currently covered by a permit
certification that covers a larger area, which includes the sold lot. In addition; Builder Bob also holds a permit
certification for other portions of the development which he already owns, and Builder Bob wishes to cover his
new lot under this certification. Developer Dan submits a request to remove the lot from his permit certification
and provides Builder Bob's permit certification number that the lot will now be covered under. Builder Bob
also submits a request to modify his permit certification to add the lot, and provides Developer Dan's permit
certification number under which the lot was previously covered. Developer Dan and Builder Bob must revise
their SWMPs to reflect the changes in their covered area and activities.

2) Permit Compliance for Multiple Owner/Operator Development
As a permittee, the most important concept for projects where multiple entities are involved is: if
2.1 activities within your permitted area result in pollution of stormwater, vou are the entity responsible for
ensuring that those pollutants are properly managed.
Permittees are responsible for complying with the Stormwater Construction Permit requirements for the.
areas and activities for which they have permit coverage, and for all BMPs they are relying on to comply _
with the permit. Properly addressing and documenting the responsibility of various parties at a
construction site will help protect an entity from liability in the case where another parry's actions result
in failure of BMPs.
a) Pollutants from Outside the Permitted Area:
A permittee may be held liable for pollutants that pass into and are then discharged from their permitted
area or that result from another entity's activities. Specifically, a permittee may have responsibility to
ensure proper implementation of BMPs to control stormwater discharges from their permitted area, even
if another entity is contributing pollutants.
The Stormwater Construction Permit requires the permittee to ensure the implementation of BMPs which will be
used to control the pollutants in stormwater discharges associated with construction activity from their permitted
area. Therefore, a permittee may be responsible for adequately implementing and maintaining BMPs that are
providing treatment for pollutants originating outside of their permitted area or from another entity's activities.
An example is when a permittee's property is being used by a separate entity for construction activities (e.g.,
loading and unloading, site access, materials storage, etc.), or BMPs located on the permittee's property are
being relied on to treat stormwater runoff from another site.
This scenario is common when a developer sells off lots to a builder. As a practical matter, what most often
occurs is that the developer must allow the builder to use the developer's infrastructure (e.g., roads, storm
drains, ponds, etc.) for activities and BMPs that cannot realistically be limited to the builder's property. In this
case, the developer remains a liable party (in addition to the builder) to ensure that proper stormwater
management is implemented for the project. Permit coverage may instead be assigned to the builder for this
infrastructure, if the builder has been designated as the operator of the area for stormwater quality purposes (See
Section B.2). However, this may not always be practical when multiple builders are operating in an area or
when the developer is still performing their own construction activities.
Refer to the Liability and Example sections, below, for further guidance.
b) BMPs Located Outside the Permitted Area:
If a permittee will be relying on BMPs that are outside of the area they own and/or operate, the specific
! actions listed below must be taken to ensure compliance with the Stormwater Construction Permit. The
permittee is responsible for ensuring the proper managment all pollutants from their permitted area.
Even if the BMP are implemented by another party, the permittee may still be liable if their pollutants
are eventually discharged.
The permittee is responsible for ensuring the operation and maintenance of all BMPs that are used to control
pollutants that originate from their activities, even if the BMPs are located outside of the area owned and/or
operated by the permittee. For example, a builder may only have ownership of a single lot, but may have to rely
on BMPs that are located off of their lot and on a developer's property to adequately manage stormwater runoff,
such as inlet protection that is on the developer's streets. If a permittee will rely on BMPs that are outside the
area that they own and/or operate, the following measures must be taken:
i) Any off -site BMPs must be documented in the permittee's SWMP. This includes structural BMPs (e.g.,
inlet protection and sediment ponds) and non-structural BMPs (e.g., concrete wash out areas and street
sweeping). By including the BMPs in the SWMP, the permittee can effectively include the practices under
their permit coverage. In such cases, the same off -site BMPs may actually be included in two or more
parties' SWMPs.
Page 8 of 10 Revised 7/07
Water Quality Control Division — Stormwater Program www.cdphe.state.co.us/wq/permitsunit
ii) The permittee must have adequate permission from the land and/or BMP owner(s) to utilize the off -site
conveyances and BMPs and to ensure proper maintenance and operation. The permittee must be able to
provide evidence of this agreement upon request.
iii) The off -site BMPs must be operated and maintained in accordance with the SWMP(s) and must control the
discharge of pollutants. It may be necessary to enter into agreements with other parties to ensure operation
and maintenance of these BMPs. Regardless of who actually carries out the operation and maintenance of a
BMP, all permittees who make use of the BMP to control pollutants from their construction activities remain
liable if the BMP is not adequately operated and maintained.
iv) All BMPs must be located prior to discharge to surface waters or municipally -owned storm sewer systems.
Liability: In the above examples, to reduce liability, the developer and builder should communicate on
stormwater management issues and document who will be responsible for specific BMPs (e.g., who will
maintain inlet protection and implement street sweeping). If BMPs are not being adequately implemented by
the party defined as responsible, the other party should take the necessary action to ensure pollutants originating
from, or passing through, their permitted area are properly controlled. It is recommended that stormwater
management responsibilities be addressed in contracts or other legal agreements between applicable owners and
operators for construction sites where one party's actions may impact another party's permit compliance. These
legal agreements will both help define roles and responsibilities at a multi owner/operator site, and also may be
used to seek damages from a contractor if monetary penalties are issued to a permittee for permit violations.
Example: Developer Dan sells a lot to Builder Bob. Following the procedures discussed in Section G. Lb or c,
above, Builder Bob obtains separate permit coverage for his new lot, ending at the curb line. Because the site
infrastructure is being utilized by several different builders at the project, Developer Dan maintains permit
coverage for the streets, storm drain system, and a large retention pond that is designed and implemented as a
BMP to manage pollutants from construction activities at the development (including Builder Bob's lot). In
addition to the large pond, inlet protection is also being used to protect storm sewer inlets located on Developer
Dan's roads, and street sweeping is occurring to control sediment tracked onto Developer Dan's roads.
Builder Bob is relying on the pond, inlet protection, and street sweeping to manage pollutants from his lot, and
therefore has included the BMPs in his SWMP, as discussed in Section G.2.b, above. The BMPs are also
included in Developer Dan's SWMP because they are being used to control pollutants from property he still
maintains control over, as discussed in Section G.2.a, above. In addition, Developer Dan and Builder Bob enter
into a contract that clearly defines Developer Dan as being responsible for implementing and maintaining the
infrastructure BMPs (i.e., the pond, inlet protection, and street sweeping BMPs), and requires Builder Bob to
implement additional BMPs on his lots, such as vehicle tracking control and construction waste management.
If the infrastructure BMPs are not properly operated and maintained, or discharges of sediment and/or other
pollutants from Builder Bob's lot are not properly controlled and overwhelm the infrastructure BMPs, both
Developer Dan and Builder Bob may be in violation of their permits. Therefore, Builder Bob and Developer
Dan must both remain diligent in ensuring that conditions of their contract are being met and BMPs operated by
both parties continue to be implemented in accordance with their SWMPs.
H. SALE OF RESIDENCE TO HOMEOWNERS
Residential lots that have been conveyed to a homeowner and that meet the specific criteria below do not
require coverage under the Stormwater Construction Permit.
In this case, the conveyed lot may be removed from coverage under the permittee's certification, and the permittee is no
longer responsible for meeting the terms and conditions of this permit for the conveyed lot, including the requirement to
transfer or reassign permit coverage. The permittee remains responsible for eventual inactivation of the original
certification (see Part F, above). The criteria for these lots are as follows:
Page 9 of 10 Revised 7/07
Water Quality Control Division — Stormwater Program www.cdphe.state.co.us/wq/permitsunit
1) The lot has been sold to the homeowner(s) for private residential use;
2) the lot is less than one acre of disturbed area;
3) all construction activity conducted by the permittee on the lot is completed;
4) a certificate of occupancy (or equivalent) has been awarded to the homeowner; and
5) the SWMP has been amended to indicate the lot is no longer covered by permit.
Lots not meeting all of the above criteria require continued permit coverage. However, the permit coverage for the
conveyed lot may be transferred or reassigned to a new owner or operator (see Parts F and G.1, above).
I. CONSTRUCTION DEWATERING
} Construction dewatering water can NOT be discharged to surface waters or to storm sewer systems
without separate permit coverage. The discharge of Construction dewatering water to the ground, under
the specific conditions listed below, may be allowed by the Stormwater Construction Permit when
appropriate BMPs are implemented.
Two options are available for managing uncontaminated Construction Dewatering water on a construction site.
Construction Dewatering water discharged from the project site, to surface waters or to storm sewer systems, is
considered a process water and requires an industrial process water permit. Applications for dischargers engaged in the
dewatering of uncontaminated groundwater from a construction. site are available from the Division's web site or by
contacting the Division (see first page for address information).
Alternatively, Construction Dewatering water may be discharged to the ground if all of the following conditions are
met:
1) The discharge and the BMPs are included in the SWMP;
2) Adequate BMPs are included to control stormwater pollution;
3) The discharge does not leave the site as surface runoff or to surface waters/storm sewer systems; and
4) The groundwater being pumped is not contaminated so as to exceed State groundwater standards.
If the above conditions are not met, a separate permit (see above) is needed for discharges to the ground and/or
surface waters.
Further information concerning Construction Dewatering, including what constitutes contamination of groundwater, can
be found in the Stormwater Construction Permit and Rationale. These documents and others can be obtained from the
Division's web site or by contacting the Division (see first page for address information).
I CONCRETE WASHOUT
! Concrete Washout water can NOT be discharged to surface waters or to storm sewer systems without
separate permit coverage. The discharge of Concrete Washout water to the ground, under the specific
conditions listed below, may be allowed by the Stormwater Construction Permit when appropriate BMPs
are implemented.
Concrete Washout water from washing of tools and concrete mixer chutes may be discharged to the ground if all of the
following conditions are met:
1) The source is identified in the SWMP;
2) Adequate BMPs are included in the SWMP to prevent pollution of groundwater; and
3) These discharges do not leave the site as surface runoff or to surface waters/storm sewer systems.
The use of the washout site should be temporary (less than 1 year), and the washout site should be not be located in an
area where shallow groundwater may be present, such as near natural drainages, springs, or wetlands.
Concrete washout water must not be discharged to state surface waters or to storm sewer systems. Also, on -site
permanent disposal of concrete washout waste is not authorized by this permit.
Further information concerning Concrete Washout can be found in the Stormwater Construction Permit and Rationale.
These documents can be obtained from the Division's web site or by contacting the Division (see first page for address).
