I. Introduction
A. SWMP Objective
The objective of this Stormwater Management Plan (SWMP) for Union Place Subdivision
First Replat, is to identify the Best Management Practices (BMP’s) which, when
implemented, will meet the requirements of the Colorado Department of Public Health
& Environment, Water Quality Control Division. According to Appendix A of the State of
Colorado General Permit Application and Stormwater Management Plan Guidance for
Stormwater Discharges Associated with Construction Activity (6/2011), the SWMP goal is
to, “describe appropriate controls and measures to improve water quality by reducing
pollutants in storm water discharges and ensure compliance with the requirements of
the storm water permit. The SWMP must be completed and implemented at the time
the project breaks ground, and revised if necessary as construction proceeds to
accurately reflect the conditions and practices at the site.”
The SWMP is a “living” document which should be modified and updated through the
course of site construction to accurately reflect site conditions at all times. Pollutant
sources should be continuously evaluated, BMP’s selected, documented, implemented,
and pollutant sources re-evaluated (and the process continued). A current copy of the
SWMP shall be kept onsite at all times. A person familiar with the SWMP and on-site
construction activities and clean-up procedures should be designated as the SWMP
Administrator for the site. The SWMP Administrator will be responsible for, but not
limited to, inspections and inspection reports, personnel training, regulatory agency
contact, SWMP implementation and revisions, field notebooks, and record keeping of
employee activities, contacts, and notifications.
References are found in the Appendix regarding some of the requirements, restrictions,
and forms related to the SWMP.
II. Site Location and Description
A. Location
The Union Place site is located in the Northeast Quarter of the Northeast Quarter of
Section 2, Township 7 North, Range 69 West of the 6
th
Principal Meridian to the City of
Fort Collins, Larimer County, Colorado.
The site is located immediately south of Willox lane, west of Willox Crossing P.U.D.
(McDonalds / gas station) and College Avenue (US 287), north of a trailer park, and east
of a residential subdivision. The future Mason Street corridor runs north-south through
the site near its eastern boundary.

B. Description of Property
The Union Place site (referred herein as “the site”, “this site) is approximately 10.3 acres
in size that will be developed into residential and commercial lots with associated
utilities and streets.
The following is a summary of the existing conditions:
Ground Cover - The site doesn’t currently contain any buildings but there are existing
utilities to the site that once serviced a residence. The existing ground cover consists
mostly of weeds and native grasses.
Grades - In general, the majority of the site slopes southeasterly at an approximately
0.6% slope.
Soil Type - According to the NRCS Web Soil Survey, the majority of the site consists of
Nunn clay loam, 0 to 1 percent slope (Soil Type C). According to the Subgrade
Investigation and Pavement Recommendations Union Place West Willox Lane Fort
Collins, Colorado by CTL Thompson Incorporated., “the results of infiltration tests
indicate design infiltration rates ranging from 0.5 to 1.5 inches per hour with a
design average infiltration rate of 1.0 inches per hour … it appears the majority of
the site would be suitable for stormwater detention or retention underneath
pervious paving.” According to the same study “ground water was measured at
depths of about 5 to 6 ½ feet below existing grades.”
Irrigation - There is an irrigation ditch running along the western property boundary.
There are no known wetlands within the site.
Utilities – Existing utilities are located within the existing street sections constructed
with the first phase of Union Place Subdivision.
Detention Ponds and Storm Sewer - One of McDonald’s detention ponds is currently
located in the southeast corner/bumpout of the site. A stubout from the McDonald’s
site has been provided to the Union Place site to accept historic flows.
C. Description of Development
The planned development for the site will consist of the following improvements:
• The construction of five (5) single family attached buildings with thirty-seven (37)
units.
• The construction of utilities to support the proposed buildings including sanitary,
water and storm drainage. These services will connect to existing mains located
within the existing streets constructed with the first phase of the Union Place
Subdivision.

D. Construction Activity Description
Construction activity (for all phases of construction) includes installation of BMP’s,
demolition, grading, infill, utility (sanitary sewer, and waterline) construction, drainage
conveyance construction, and building construction.
E. Proposed Sequence for Major Activities
The sequence for major construction activities includes the installation of BMP’s, site
demolition activities, grading and infill, major drainage conveyance construction,
installation of other utilities (underground water main and services and sanitary sewer
main and services), final grading of building pad, building construction, final site grading
and landscaping.
The following is the expected sequence of phasing for this site.
• Installation of erosion control
• Site demolition activities
• Site grading and infill
• Installation of utilities
• Installation of permanent vegetation in open areas
• Construction of new buildings
• Installation of sidewalks
• Installation of permanent landscape vegetation
Construction for the replat area is estimated to begin March 2015 and be completed by
March 2016.
F. Area Estimates
The site has a platted area of 10.3 acres. The total area subject to disturbance by
construction of this replat project is approximately 1.6 acres.
This SWMP does not include additional offsite area (for staging, material storage,
overburden stockpiles of dirt, borrow areas, etc.) other than that mentioned above.

According to the NRCS Web Soil Survey, the majority of the site consists of Nunn clay
loam, 0 to 1 percent slope (Soil Type C). According to the Subgrade Investigation and
Pavement Recommendations Union Place West Willox Lane Fort Collins, Colorado by CTL
Thompson Incorporated., “the results of infiltration tests indicate design infiltration
rates ranging from 0.5 to 1.5 inches per hour with a design average infiltration rate of
1.0 inches per hour … it appears the majority of the site would be suitable for
stormwater detention or retention underneath pervious paving.” According to the same

study “ground water was measured at depths of about 5 to 6 ½ feet below existing
grades.”
H. Location and Description of Potential Pollution Sources
This section focuses on the identification of the potential pollutant sources and briefly
discusses the Best Management Practices (BMPs) that will be used. More information
on the BMP’s utilized on this site is included in the next section “III. BMPs for
Stormwater Pollution Prevention”.
1. All disturbed and stored soils;
It is expected that there will be stockpiles of dirt on the site from the utility installations
and the foundation excavation. For this site, stockpiles should be located in areas
where Silt Fence or Straw wattles may be placed around the individual stockpiles to
contain the runoff (i.e. landscaped or disturbed earth areas).
2. Vehicle tracking of sediments
It is anticipated that the contractor will access the property from existing private drives
adjacent to the site. As all roadways adjacent to the site are paved, it is not anticipated
that vehicle tracking control pads will be required onsite during construction. However,
at the end of each workday, the Contractor shall sweep or scrape the adjacent private
drives of sediment that may have accumulated during the workday.
3. Management of contaminated soils
There are not any known contaminated soils on the site. However, if the contractor
encounters contaminated soils during the construction process they should stop
construction immediately and notify the appropriate government authorities in
accordance with good construction safety and practice.
4. Loading and Unloading operations
Loading and unloading will take place on the site. Truck access should be limited to the
extent possible to locations within the disturbed limits of the project. BMP’s such as silt
fence in non-paved areas and rock socks in paved areas should be placed to keep
sediment from exiting the disturbed area limits, primarily towards the south and east as
these are the low sides of the site.
5. Outdoor storage activities (building materials, fertilizers, chemicals, etc.)
Storage of onsite materials including building materials, fertilizers, waterline, and
sanitary sewer will be covered and placed on pallets to prevent direct contact with the
ground and potential surface runoff.
Stormwater Management Plan
Union Place First Replat
Fort Collins, CO
6 U13003-SWMP.docx
6. Vehicle and equipment maintenance
Vehicle and equipment maintenance should be performed offsite or onsite within an
area surrounded by silt fence or straw wattles. Vehicle and equipment maintenance
shall not happen along the adjacent public streets. At a minimum, all vehicle and
equipment maintenance shall be performed on the hard surface or gravel areas at least
50’ from any stormwater feature (i.e. inlet, storm sewer, concentrated runoff, swale,
etc.)
7. Significant dust or particulate generating processes
The Contractor shall comply with applicable air pollution control requirements of the
City of Fort Collins. The Contractor shall take appropriate actions to minimize
atmospheric pollution and take reasonable precautions which shall include, but not be
limited to:
1. The use of water for control of dusts for construction processes such as
demolition, grading, or the clearing of land.
2. Covering, at all times when in motion, open-bodied trucks transporting
materials likely to give rise to airborne dusts.
3. Require lower speeds for vehicles entering, exiting, and driving within the
project limits to minimize the amount of dust disturbed by moving vehicles.
8. Routine maintenance activities involving fertilizers, pesticides, detergents, fuels,
solvents, oils, etc;
Chemicals, fuels, lubricants, and paints typical with building construction stored on-site
will be in water tight containers and covered as necessary and stored in a bermed area,
a storage building, or within a vehicle to act as secondary containment.
9. On-site waste management practices (waste piles, liquid wastes, dumpsters, etc.);
1. Waste piles should be covered or surrounded by silt fence or straw wattles.
Liquid wastes should be collected and stored in covered containers and
disposed of properly.
2. Solid waste materials, including disposable materials incidental to the major
construction activities, will be collected in on site dumpsters. The containers will
be emptied periodically and trucked away from the site. Dumpsters should have
covers.
10. Concrete truck / equipment washing, including the concrete truck chute and
associated fixtures and equipment;
A dedicated concrete washout area is necessary for this project. The contractor shall
clean out equipment within the washout area so that runoff is not allowed to leave site
and enter the public streets or neighboring properties.

Union Place First Replat
Fort Collins, CO
7 U13003-SWMP.docx
11. Dedicated asphalt and concrete batch plants;
There will not be dedicated asphalt or concrete batch plants on this site.
12. Non-industrial waste sources such as worker trash and portable toilets
Worker’s trash shall be disposed of in an onsite dumpster. The site should be free of
trash at the end of each working day.
Portable toilets shall be utilized by construction personnel and serviced regularly by a
commercial operator. They shall be located a minimum of 5 feet from the curb or 50
feet from inlets. If sanitary facilities are located on a paved surface, toilets shall be
equipped with a containment pan or a secondary containment BMP. Regardless of
location all portable toilets shall be anchored per manufacturer recommendations.
13. Other areas or procedures where potential spills can occur.
BMP’s such as tarps and drip pans should be used for painting, stucco, dry-wall, etc.
operations
I. Non-Stormwater Components of Discharge
According to the CTL Thompson Report, groundwater was observed at depths of
approximately 5 to 6.5 feet below ground surface. At these depths, it is possible that
groundwater may be encountered during construction. Where groundwater is
encountered during trenching or excavation operations, a temporary
sediment/retention basin should be constructed to store pumped dewatering flows.
The other non-storm water components of discharge include, but are not limited to,
water line flushing, irrigation to establish seeding, and watering for dust mitigation, and
compaction. It is important for the contractor to manage the runoff from these items
utilizing the BMP’s mentioned in this report (i.e. silt fence, straw waddles, concrete
washout areas, surface roughening, etc.).
J. Receiving Waters
The site lies within the Dry Creek Basin. The vast majority of the proposed site will drain
via overland flow, grass lined swales, street sections and storm drains to the existing
regional pond located southeast of the site. Upon exiting the regional pond, runoff from
the basin empties into the Dry Creek Basin and ultimately drains to the Poudre River
through a series of inlets, culverts, and channels.

III. BMPs for Stormwater Pollution Prevention
A. Erosion and Sediment Controls
Once construction activity begins, Best Management Practices (BMP’s) intended to
contain sediment onsite must be constructed, inspected, and repaired as necessary.
Such controls must be functional before upslope land disturbance takes place. The
BMP’s will be installed as shown on the SWMP Map shown in Appendix A. They must be
supplemented as on-site experience proves necessary in order to control sediment,
pollutant discharge, and ensure public safety.
The following temporary and permanent BMP’s will be installed and maintained to
control on-site erosion and prevent sediment from traveling off-site during construction.
Temporary BMP’s
• Construction Fence is a temporary BMP. The contractor is to place construction
fencing around development as needed to limit access by construction equipment
and personal vehicles to designated areas of ingress and egress.
• Inlet Protection is a temporary BMP that helps prevent soil and debris from the site
from entering the storm drain inlets and usually consists of a sediment filter around
or upstream of the storm drain inlet. Inlet protection allows storm water to flow
into the drain but only after excess sediment has been filtered out. Inlet protection
will be used on existing and proposed storm inlets and will be installed at such time
as construction of the storm sewer system occurs. Inlet protection for this site will
consist of:
o Wattles, which are meshed netting “tubes” filled with straw, excelsior, or
coconut fiber placed around grated inlets and curb inlets. Wattles require
proper installation and maintenance to ensure their performance. Sizing shall be
per manufacturer’s recommendation.
o Block and Gravel Filters, which are comprised of cinder blocks stacked to a
height of 24 inches surrounding the drop inlet perimeter and further surrounded
by 1-1/2" gravel enclosed in wire mesh.
o Silt Fence Boxes, which are wooden frames surrounded by geotextile fabric. The
frame shall consist of (4) 3-foot tall stakes connected by a 2x4 wooden frame at
the top. The stakes shall be driven into the ground such that the height of the
top of the stakes and frame is no more than 18 inches above the ground.
Geotextile fabric shall be fastened to all four sides of the wooden frame and the
bottom edge of the fabric shall be buried to a depth of 6 inches. The frame and
fabric shall be configured such that any runoff approaching the inlet shall pass
through the fabric.
Stormwater Management Plan
Union Place First Replat
Fort Collins, CO
9 U13003-SWMP.docx
• Regular Meetings are a temporary and non-structural BMP. Regular meetings with
on-site workers including builders, suppliers, landscape personnel, etc. should be
conducted so that they are kept up to date with site standard operating procedures.
• Silt Fence is a woven synthetic permeable fabric that filters runoff. Silt fence is a
temporary barrier that is installed prior to earthmoving activities and is placed
downstream of areas where runoff from construction activities is expected to occur,
especially along the site perimeter to allow sediment to settle from runoff before
water leaves the construction site. Silt fences will be installed per manufacturer’s
recommendations. Silt fence encourages sheet flow and is not intended to be used
in areas of concentrated flow. If concentrated flow is encountered during the
placement of the fence, an alternative BMP shall be used and the SWMP should be
updated to reflect this change.
• Staging Areas will be provided during the construction process at least 100’ from
any storm water conveyance. Staging areas include locations for vehicle fueling,
concrete truck washout, material storage and transfer, equipment maintenance and
cleaning, and other construction activities. These areas will be maintained as
isolated locations that allow for contaminants to be concentrated and removed from
the site as necessary. Concrete washout areas shall be designed such that washout
water cannot leave the location, nor shall storm water runoff wash concrete from
the locations.
• Straw Wattles are a temporary BMP that are used for a variety of purposes. They
are used for inlet protection, curbside check dams, swale protection, at the bottom
of slopes, or the limits of property boundaries. They are easy to install and are
increasingly being used for Small Site SWMP’s. The straw wattles, which are meshed
netting “tubes,” filled with straw, excelsior, or coconut fiber. Wattles for swale
protection should be installed following rough grading of channel areas. Wattles
require proper installation and maintenance to ensure their performance.
• Surface Roughening is provided following grading activities to slow the effects of
wind erosion. Roughening can be used as a temporary BMP and is a technique used
for creating unevenness on bare soil through the construction of furrows (groove
cuts) running across a slope or by utilization of construction equipment to track the
soil surface. The primary function of surface roughening is to reduce erosion
potential by decreasing runoff velocities, reducing the length of sheet flow trapping
sediment, and increasing infiltration of water into the soil.
• Temporary Seeding is the establishment of a temporary vegetative cover on a
graded area that will be exposed for longer 30 days. Temporary seeding can be used
on areas requiring temporary protection that will eventually need permanent
Stormwater Management Plan
Union Place First Replat
Fort Collins, CO
10 U13003-SWMP.docx
vegetation at the completion of the construction or it can be used for areas that will
be re-disturbed after a period of inactivity. The seed mix 100% smooth brome at a
minimum application rate of 30 pls/lbs/acre. Fertilizer and Mulch shall be included
as specified on the plans.
• Wattle Sediment Protection is a temporary BMP that are typically used as check
structures in areas of concentrated water flow such as swales, grassed waterways,
and down drains. They can be installed in combination with any type of rolled
erosion control blanket or channel liner and function by slowing water velocity,
settling out sediment, and preventing undermining of the channel lining material.
Wattles for swale protection should be installed following rough grading of channel
areas. Sizing and spacing shall be per manufacturer’s recommendation.
• Wind Borne Sediment and Dust Control measures will be provided during the
construction process to control wind borne sediment. During grading activities,
water will be applied to the disturbed soils for the purpose of maintaining cohesion
with clay type soils and also to meet moisture requirements for compaction of
disturbed soils. Other measures of mitigation for wind erosion may include the
timely installation of seed and mulch following the establishment of final grade, and
the timely installation of pavement following completion of utility trenching
operations and curb construction. Open areas should be kept in a roughened
condition (see Surface Roughening above).
Permanent BMP’s
• Grass-Lined Swales (included as part of permanent seeding or other permanently
stabilized swales) are permanent landscaped channels constructed generally below
grade to convey runoff or channel water to a desired location. The grass-lined areas
allow for infiltration to occur as well as including a flow path across a vegetated
surface slowing the conveyance rate of storm water runoff.
• Permanent Seeding and Planting is the establishment of a permanent perennial
vegetation such as trees, shrubs, vines, grasses/sod, or legumes on exposed areas
for final permanent stabilization in order to provide stabilization of the soil by
holding soil particles in place. These items should be installed as per the approved
Landscape Plan. Soil Amendments shall be incorporated in all landscape areas to a
depth of 6” at a rate of 3 cubic yards per 1000 square feet of area unless 4” of loose
topsoil have been imported onto the site over 4” of loosened subgrade soils.
Permanent Landscaping reduces storm water runoff velocity, maintains sheet flow,
protects the soil surface from erosion, promotes infiltration of runoff, and improves
wildlife habitat.
Stormwater Management Plan
Union Place First Replat
Fort Collins, CO
11 U13003-SWMP.docx
• Preservation of Existing Vegetation should occur where no construction activity is
expected to occur. Preservation of natural vegetation is generally a permanent BMP
and is applicable to construction sites with pre-existing vegetation. Only land
needed for building activities and vehicle traffic needs is to be cleared.
B. Erosion Control Sequencing
This project will have three distinct erosion control phases. The initial phase will be
installing erosion control items prior to any construction on the site. After the initial
erosion control items have been installed, the next phase will consist of site demolition
and rough grading activities. Following completion of the demolition and rough grading,
construction of the infrastructure (utilities and development of landscaped areas) will
be conducted. The final stage will include the construction of the new buildings and site
hard surfaces including driveways, sidewalks and parking areas. Each of the phases is
described below, including necessary erosion control items.
A SWMP drawing is located in the Appendix that includes the minimum required BMP’s
found on the Sediment and Erosion Control Plans. It should be filled in with the
appropriate BMP’s as they are constructed/placed within the project site.
Phase 1 – Prior to Construction
• Preserve Existing Vegetation – Before construction commencement, areas that are
not disturbed by construction activity should be preserved as needed with
construction fencing, silt fencing, signage, or other means to keep vehicular traffic
out of the area to be left undisturbed.
• Wattles – Before construction commencement, wattles will be placed downstream
of areas where runoff from construction activities is expected to occur.
• Staging Area – A concrete wash out area, fueling area, and other staging areas will
be provided during the construction process at least 100’ from any storm water
conveyance. A staging area is to be shown on the SWMP drawing when its location
is identified.
Phase 2 – Site Demolition, Site Grading, and Infrastructure Construction
The items installed in Phase 1 shall be in place, functional, and maintained during and
following the site demolition and site grading operations. In addition to those items, the
following BMP’s shall be installed.
Stormwater Management Plan
Union Place First Replat
Fort Collins, CO
12 U13003-SWMP.docx
• Wind Borne Sediment and Dust Control – Wind borne sediment and dust control
measures should be implemented during grading activities. This will be particularly
important to consider prior to the establishment of seeding.
• Inlet Protection – Wattles will be placed at curb inlets and area inlets located
throughout the site immediately after the inlet is constructed / installed. Existing
inlets shall be protected prior to heavy equipment staging, demolition, or
commencement of construction activities.
• Swale Protection – Straw wattles will be placed within the swales immediately
following rough grading. Wattles shall be placed across the swale for every 2’ of
drop in swale elevation or every 300'.
• Slope Protection – Surface roughening and contour furrows shall occur after rough
grading.
• Permanent Seeding – Permanent seeding or landscaping shall be placed
immediately in areas that are final graded and where little future disturbance is
expected.
• Temporary Seeding – The majority of the landscaped areas will be permanently
seeded or planted. However, if disturbed areas are left without permanent
stabilization 30 days after grading, temporary seeding will be required.
Phase 3 – Building Construction and Roadway, Sidewalk, and Parking Area Construction
This phase will likely begin before the seeding has been established throughout the site,
so it is expected that majority of the BMP’s shown in Phase 1 and Phase 2 will be in
place at the beginning of this phase. As sidewalks are installed and seeding/landscaping
is established there will be previously placed BMP's such as some sections of wattles
that may be removed. There are other items such as inlet protection, wattles, and
swale protection that may only be removed after all construction is complete and
upstream areas are established.
C. Materials Handling and Spill Prevention
The site development includes appropriate construction staging and stockpile areas
identified on the SWMP Plans shown in Appendix A. Stormwater runoff generated from
the staging areas will be routed to a temporary sedimentation area where runoff will be
contained and filtered before being discharged downstream. The staging/stockpile
area(s) may be moved to a location no closer than 100’ from a storm water conveyance.
Vehicle tracking control should be placed at the stockpile area entrance/exit and silt
Stormwater Management Plan
Union Place First Replat

fence should surround it. If relocated, the SWMP should be updated with the actual
location of the stockpile/staging area(s).
Chemicals, fuels, lubricants, and paints typical with building construction stored on-site
will be in water tight containers and covered as necessary and stored in a bermed area,
a storage building, or within a vehicle to act as secondary containment. Storage of
onsite materials including building materials, fertilizers, waterline, sanitary sewer, and
storm sewer will be covered and placed on pallets to prevent direct contact with the
ground and potential surface runoff.
Other hazardous waste disposal (that is not typical to residential building construction)
is not included within this SWMP. Concrete and asphalt batch plants are not anticipated
on this site and thus are not included in this SWMP.
In the event of a spill or accident, it shall be contained and disposed of so that it will not
flow from the site or soak into the soil. Once construction is completed, concrete waste
and contaminated soil will be disposed of properly. The SWMP Administrator should be
notified of spills.
IV. Other Controls
The following includes other measures to control pollutants:
• Solid waste materials, including disposable materials incidental to the major
construction activities, will be collected in containers. The containers will be emptied
periodically and trucked away from the site. Dumpsters shall have covers.
• Water used to establish and maintain grass, for dust control, and for other purposes
during the construction phase must originate from a public water supply or private well
approved by the Colorado Department of Public Health and Environment unless
otherwise approved.
• Sanitary facilities shall be provided at the site throughout construction activities. They
shall be utilized by construction personnel and serviced regularly by a commercial
operator. They shall be located a minimum of 5 feet from the curb or 50 feet from
inlets and must be anchored. If sanitary facilities are located on a paved surface, a
secondary containment BMP will need to be constructed.
• Access off of paved roads should be limited.
• BMP’s such as tarps and drip pans should be used for painting, stucco, dry-wall etc.
operations.

V. Final Stabilization and Long-term Stormwater Quality
Final stabilization is reached when all soil disturbing activities at the site have been completed
and vegetative cover has been established with a density of at least 70 percent of pre-
disturbance levels or when equivalent permanent erosion reduction methods have been
utilized. Upon final stabilization, temporary BMP’s may be removed, unless they are required
to remain in place for future phasing.
Water quality enhancements are provided in areas where grass-lined swales are provided for
storm water conveyance. The soft bottom/overbank areas allow for infiltration to occur as well
as including a flow path across a vegetated surface slowing the conveyance rate of storm water
runoff.
VI. Inspection and Maintenance Procedures
Upon completion of each phase of construction, appropriate measures shall be taken to inspect
and maintain existing erosion control features, as described herein or per manufacturers
specifications (whichever is more stringent) and install new erosion control elements associated
with each phase of construction.
The temporary BMP’s will be inspected and documented at a minimum of once every 14 days
and after each precipitation or snowmelt event. The SWMP will be kept up-to-date with
inspection records, maintenance procedures, and changes. Records should include complete
inspection reports for each inspection, maintenance, and/or repair. A record-keeping system is
recommended in managing inspection and maintenance reports and should include all
maintenance records, spill response, weather conditions, training, correspondence, etc. A
blank copy the CDOT Stormwater Field Inspection Report is provided in Appendix C.
Preventative maintenance also involves the regular inspection and testing of equipment, timely
maintenance of the equipment, and complete records of the maintenance and inspections of
the equipment. The maintenance and inspection records should be kept on site and made
available upon request.
Inspections must include the observation of the construction site perimeter, runoff discharge
points, disturbed areas, staging areas (including concrete washout areas and fueling areas),
erosion and sediment control measures identified in this SWMP, and any other structural BMP’s
that may require maintenance. The inspection must determine if there is evidence of or
potential for pollutants to enter the drainage system and if they should be modified, replaced,
or added to.
The following list includes some recommended maintenance procedures:
Stormwater Management Plan
Union Place First Replat
Fort Collins, CO
15 U13003-SWMP.docx
• Erosion and sediment control measures determined, upon inspection, to be in need of
repair shall be maintained before the next anticipated storm event or as necessary to
maintain continued effectiveness of erosion and sediment control measures. If it is
impractical to maintain erosion and sediment control measures before the next storm
event, maintenance should be accomplished as soon as practical.
• Locations where vehicles enter or exit the site shall be inspected for evidence of sediment
being tracked off-site by construction traffic. Such sediment shall be removed before it can
be conveyed to the receiving storm drains or creeks.
• Seeded areas will be checked to see that grass coverage is maintained. Areas will be
watered, fertilized, and reseeded as needed.
• It is the responsibility of the Site Operator to maintain effective pollutant discharge
controls. Actual physical site conditions or contractor practices could make it necessary to
install more control than are shown on the Erosion Control Plan. For example, localized
concentrations of surface runoff or unusually steep areas could require additional erosion
control devices. Assessing the need for, and implementing additional controls will be a
continuing aspect of the SWMP until final stabilization. This plan intends to control water-
borne and liquid pollutant discharges by some combination of interception, filtration, and
containment. Parties implementing this plan must remain alert to the need to periodically
refine and update the plan in order to accomplish the intended goals.
• Sediment that has escaped the construction site must be removed at a frequency sufficient
to minimize off-site impacts.

Applicability
Appendix A – Preparing a Stormwater Management Plan (SWMP)
APPLICABILITY
This application is for use by all entities engaged in construction activities to obtain coverage under the general permit for
Stormwater Discharges Associated with Construction Activities (the Stormwater Construction Permit). 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.
Stormwater Construction Permit coverage is required by State and Federal regulations for stormwater discharged 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). 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. 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, and all portions of the project must be covered.
NOTES:
Stormwater Management Plan Preparation Guidance – The guidance, available as Appendix A to this application,
has been revised and updated.
Additional Guidance – Additional information, including further discussion on permittee and operator liability, is
available in the Stormwater Fact Sheet – Construction, available from the Division‘s web site at
www.cdphe.state.co.us/wq/PermitsUnit. If you have questions on completing this application, you may contact the
Division at cdphe.wqstorm@state.co.us or (303) 692-3517.
Water Quality Control Division – Stormwater Program www.cdphe.state.co.us/wq/permitsunit
Instructions – Page 2 of 3 Revised 6/2011
INSTRUCTIONS
A) Submitting the Application
Application Due Date: At least ten days prior to the anticipated start of construction, the owner or operator of the
construction activity must submit an application as provided by the Water Quality Control Division (Division). This
form may be reproduced, and is also available from the Division‘s web site (see previous page for address/contact
information). Applications received by the Division are processed, and a permit certification and other relevant
materials will be sent to the attention of the legally responsible person .
Permit Fee: Do not send any payment with this application. You will be billed once you 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: The application must be completed accurately and in its entirety or the application will
be deemed incomplete—processing of the application will not begin until all required information is received. One
original copy of the completed application (no faxes or e-mails) must be submitted to the Division to initiate the
application process (see page 1 above for address/contact information).
Do not include a copy of the Stormwater Management Plan, unless requested by the Division.
B) Who May Apply For and Maintain 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.
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.
Water Quality Control Division – Stormwater Program www.cdphe.state.co.us/wq/permitsunit
Instructions – Page 3 of 3 Revised 6/2011
C) 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 owned and operated by separate entities), it is essential
that the permittees, owners, and operators at the site correctly follow the guidance on who may apply for coverage
under the Stormwater Construction Permit (see Part B, above).
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 that sold lot. This may be accomplished in one of the
following ways:
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
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.
A more detailed explanation is available in the Stormwater Fact Sheet – Construction, available from the Division‘s
web site (see page 1).
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 construction project described and
applied for, until such time as the application is amended or the certification is transferred,
inactivated, or expired.
Detailed instructions for filling out the application are included in the application.

A. INTRODUCTION
This guidance document is designed to help you develop a Stormwater Management Plan (SWMP) for your construction
project, as required for compliance with the CDPS general permit for Stormwater Discharges Associated with Construction
Activities (the Stormwater Construction Permit). It explains what each of the SWMP requirements means, and gives some
options for you to consider in developing Best Management Practices (BMPs) that are best suited to your site during
construction.
This guidance document primarily addresses the SWMP requirements in the Stormwater Construction Permit. Other
requirements and limitations, such as records retention, reporting, inspections, etc., are detailed in the Stormwater Construction
Permit itself. Also note that the SWMP and the Stormwater Construction Permit only cover discharges of stormwater.
Stormwater Management Plan (SWMP) Goal: 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. The SWMP must be completed and implemented at the time the project breaks ground,
and revised as construction proceeds, to accurately reflect the conditions and practices at the site.
Construction activities use and produce many different kinds of pollutants which may impact water quality. 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. For example, 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 of 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 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. 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 petroleum products, fertilizers, pesticides and herbicides, and building materials such as asphalt,
sealants and concrete, which may pollute stormwater. These materials can be harmful to humans, plants and aquatic life.
B. GENERAL GUIDANCE
BMPs: Best Management Practices (BMPs) encompass a wide range of erosion and sediment control practices, both
structural and non-structural in nature, that are intended to reduce or eliminate any possible water quality impacts from
stormwater leaving a construction site. The individual BMPs appropriate for a particular construction site are largely
dependant of the types of potential pollutant sources present, the nature of the construction activity, and specific-site
conditions.
Water Quality Control Division – Stormwater Program www.cdphe.state.co.us/wq/permitsunit
Appendix A - Page 3 of 20 Revised 6/2011
Best Management Practices to prevent the
erosion and discharge of sediment typically
include:
1. Erosion Control BMPs
Practices to prevent the erosion of soil.
Examples:
minimizing the amount of disturbed soil
through phasing, temporary stabilization, or
leaving existing vegetation
diverting runoff around disturbed areas
2. Sediment Control BMPs
Practices to remove sediment from runoff.
Examples:
retaining stormwater in ponds or behind silt
fence to settle out sediment
filtering stormwater through filter fabric on
inlets
Nonstructural BMPs, such as preserving natural vegetation,
preventive maintenance and spill response procedures, schedules of
activities, prohibition of specific practices, education, and other
management practices are mainly operational or managerial
techniques.
Structural BMPs include treatment processes and practices
ranging from diversion structures and silt fences, to retention ponds
and inlet protection.
Most of the BMPs referenced here are widely used in the
construction industry. They generally involve a simple and low
cost approach, and can be very effective when properly installed
and maintained.
The Stormwater Construction Permit requires the use of a self-
designed SWMP. This plan is based on the use of BMPs. For
construction sites, there are several types of BMPs: those that
prevent erosion, those that prevent construction materials from
introducing pollutants to stormwater, and those that remove
sediment and other pollutants before they can be discharged (see box, to right).
Implementation: The SWMP focus is primarily on controls used during ground surface disturbing activities. This focus
means that many sediment control BMPs, such as silt fence and inlet protection, must be installed before disturbing activities
begins, not after.
Common Sense Approach: Your SWMP is intended to be a usable document, not a paper exercise. Therefore, do not
include practices that may sound good, but are unreasonable or not feasible for your site. Failure to implement your SWMP,
even if the BMPs listed do not make sense, puts you in automatic violation of the Stormwater Construction Permit. For
example, a blanket statement that runoff from all disturbed areas will be controlled by silt fences, even if the slope or channels
are too steep/narrow for this particular BMP, would be unreasonable.
On the other hand, if a particular BMP is listed in the SWMP, but then later turns out to be impractical or ineffective, the
SWMP must be amended to reflect the changes/improvements made.
SWMP Items, Format: When preparing your plan, make sure to address each item included in this guidance. If it is not
applicable to your site, briefly explain why. A simple "Not Applicable" is not enough. Failure to address each item is a
violation of the Stormwater Construction Permit.
In addition, your SWMP should follow the same format as the SWMP requirements listed in Section C, below. That is, even if
you are using an existing document (such as plans and specs) that addresses the required SWMP items, you should include a
cross-reference for each of the SWMP items that indicates where it can be found in your existing document. You must be
able to provide all required components of the SWMP to a State, EPA, or local agency inspector at your site, so the location
and format of the information must be clear to the site personnel in charge of SWMP implementation.
Existing Controls: Note that the SWMP should include any existing stormwater controls at your site, not just new or
proposed ones. It can also include any erosion, sediment or drainage controls which are required by other regulations, such as
local erosion and sediment control ordinances, if you are also using them to meet the SWMP requirements.
Control Implemented by Other Parties: A permittee will often have to rely on controls implemented by other parties to
ensure adequate management of stormwater runoff. For example, if a permit certification is obtained to cover a lot in a larger
Water Quality Control Division – Stormwater Program www.cdphe.state.co.us/wq/permitsunit
Appendix A - Page 4 of 20 Revised 6/2011
agreements must exist between the permittee and the party implementing the BMP(s) to ensure adequate operation and
maintenance of those BMPs. Additional guidance is available in the Stormwater Fact Sheet for Construction, available from
the Division‘s web site at www.cdphe.state.co.us/wq/PermitsUnit.
SWMP Availability: A copy of the SWMP must be kept on site, readily available to the operator, and to Division or EPA
personnel for review during inspections. City, county, and local agencies may also request the SWMP as part of a local
oversight program. 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.)

C.1 SWMP GENERAL REQUIREMENTS
Permit
Part I.B Stormwater Management Plan (SWMP) - General Requirements
1. A SWMP shall be developed for each facility covered by this permit. The SWMP shall be prepared in accordance with
good engineering, hydrologic and pollution control practices. (The SWMP need not be prepared by a registered
engineer.)
2. The SWMP shall:
a) Identify all potential sources of pollution which may reasonably be expected to affect the quality of stormwater
discharges associated with construction activity from the facility;
b) Describe the practices to be used to reduce the pollutants in stormwater discharges associated with construction
activity at the facility; and ensure the practices are selected and described in accordance with good engineering
practices, including the installation, implementation and maintenance requirements; and
c) Be properly prepared, and updated in accordance with Part I.D.5.c, to ensure compliance with the terms and
conditions of this permit.
3. Facilities must implement the provisions of the SWMP as written and updated, from commencement of construction
activity until final stabilization is complete, as a condition of this permit. The Division reserves the right to review the
SWMP, and to require the permittee to develop and implement additional measures to prevent and control pollution as
needed.
4. The SWMP may reflect requirements for Spill Prevention Control and Countermeasure (SPCC) plans under section
311 of the CWA, or Best Management Practices (BMPs) Programs otherwise required by a separate CDPS permit, and
may incorporate any part of such plans into the SWMP by reference, provided that the relevant sections of such plans are
available as part of the SWMP consistent with Part I.D.5.b.
For any sites with permit coverage before June 30, 2007, the permittee’s SMWP must meet the new SWMP requirements as
summarized in Section II.I of the rationale. Any needed changes must be made by October 1, 2007.
The General Requirements section provides the broad expectations for the preparation, contents and implementation of a
SWMP. The specific items that must be included in the SWMP are addressed in the SWMP Contents sections below.

Appendix A - Page 5 of 20 Revised 6/2011
C.2 SWMP CONTENTS – Narrative Site Description
Permit
Part I.C.1 Stormwater Management Plan (SWMP) – Contents: Site Description
The SWMP shall include the following items, at a minimum:
Site Description. The SWMP shall clearly describe the construction activity, to include:
a) The nature of the construction activity at the site.
b) The proposed sequence for major activities.
c) Estimates of the total area of the site, and the area and location expected to be disturbed by clearing, excavation,
grading, or other construction activities.
d) A summary of any existing data used in the development of the site construction plans or SWMP that describe the
soil or existing potential for soil erosion.
e) A description of the existing vegetation at the site and an estimate of the percent vegetative ground cover.
f) The location and description of all potential pollution sources, including ground surface disturbing activities
(see Part I.A.2.b), vehicle fueling, storage of fertilizers or chemicals, etc.
g) The location and description of any anticipated allowable sources of non-stormwater discharge at the site, e.g.,
uncontaminated springs, landscape irrigation return flow, construction dewatering, and concrete washout.
h) The name of the receiving water(s) and the size, type and location of any outfall(s). If the stormwater discharge
is to a municipal separate storm sewer system, the name of that system, the location of the storm sewer
discharge, and the ultimate receiving water(s).
This part requires a narrative description of the overall scope and physical characteristics of the project, as follows:
a) Include a description of the construction activities at the site (e.g., type of project, a summary of the grading activities,
installation of utilities, paving, excavation, landscaping, etc) and the final disposition of the property.
b) Describe the sequence of events involved in the construction project, such as grading, excavation, etc.
c) This information, which is also required in the application, is useful in determining the extent of control measures needed.
d) Data describing soils or erosion potential will typically not be needed. This information only needs to be included if it was
used in development of the SWMP, such as for BMP design.
e) It is necessary to include the percentage of existing vegetative ground cover in order to determine, after construction, when
the site has been finally stabilized. See Part I.C.4 of the Stormwater Construction Permit (also Section C.5 of this
document), for final stabilization criteria. Final stabilization of the site is necessary before coverage under the Stormwater
Construction Permit can be terminated.
f) Describe all materials and activities at the site that may have an impact on stormwater. These may include such things as:
ground disturbing activities; equipment or vehicle washing; fertilizers, chemicals, or other materials storage; vehicle
maintenance or fueling; waste incineration, treatment, storage or disposal; haul roads; off-site vehicle tracking;
loading/unloading areas, etc.
g) Will there be any discharge from the project site during construction that is not from stormwater? If so, describe the
source and how it will be handled.
h) The receiving water information is also required in the permit application. For example, "runoff from the east side of the
site will go to a roadside ditch which discharges to Jimmy Smith Gulch; runoff from the west side of the site will go to an
unnamed tributary to Westerly Creek."

Appendix A - Page 6 of 20 Revised 6/2011
C.3 SWMP CONTENTS – Site Map
Permit
Part I.C.2 Stormwater Management Plan (SWMP) – Contents: Site Map
The SWMP shall include a legible site map(s), showing the entire site, identifying:
a) construction site boundaries;
b) all areas of ground surface disturbance;
c) areas of cut and fill;
d) areas used for storage of building materials, equipment, soil, or waste;
e) locations of dedicated asphalt or concrete batch plants;
f) locations of all structural BMPs;
g) locations of non-structural BMPs as applicable; and
h) locations of springs, streams, wetlands and other surface waters.
A site map must be developed for each construction project. The site map must show those items listed above. It does not
need to be drawn to scale, but it should be legible and easy to read. Maps that are part of the construction plans, such as a
grading plan, are a good base for developing the site map, if they are amended to include all required information as discussed
below. Local municipalities may also have maps suitable as bases to begin mapping procedures. If no other suitable base
maps are available, one must be developed. Regardless of the source of the base map, the site map needs to be of suitable
scale to show the construction portion of the site and the features within it.
Using Construction Plans, Plans Developed to Meet Local Stormwater Requirements, or Other Plans:
In many cases, some of the information required for the SWMP will also be included in items such as construction plans,
documents developed for a local stormwater program, material management plans, etc. These materials may be used to
meet the SWMP requirements, if they are amended and/or supplemented to include all required information. If the
SWMP will be incorporated into the construction plan, all of the required narrative information must also be included in
the plans, or developed as a separate document. If a separate document is used for some of the information not in the
construction plans, or if the information will be included in several locations, the permittee must still be able to provide
all required components of the SWMP to a State or EPA inspector. If this approach is used, it is highly recommended
that an index be provided that references the location(s) of all information required for the SWMP.
In addition to the items specifically mentioned in the permit, above, it is useful to also indicate on the map the following:
Drainage basins for each outfall – Field inspection can usually accomplish this task with acceptable accuracy. Look for
high areas such as crests of hills, parking lots, roads, etc., which would form the division between drainages. Gullies and
swales are indicators of stormwater flow direction. Obviously, if runoff is observed during a storm, most uncertainties can
be eliminated. The drainage areas shown should include the portions of the site where the activities described in I.C.1.f of
the Stormwater Construction Permit (see the permit language in Section C.2, above) occur, as well as those portions (such
as upslope areas) contributing stormwater that mixes with runoff from the construction area.
Surface water bodies – Mark on the site map any surface water bodies, including dry water courses, lakes, streams,
springs, wetlands, detention ponds, roadside or irrigation ditches, etc. These do not necessarily need to be within the
construction portion of the site, but may be adjacent to it or impacted by stormwater runoff. Also include any existing
storm sewers.
Existing and planned structural stormwater pollution control measures – Show on the map the location of any structural
stormwater pollution control measures, such as detention ponds, diversion ditches, covered material storage areas, fuel
farm secondary containment structures, etc. Refer to the guidance on how to ―Document Selected BMPs in the SWMP‖ in
Section C.4, below.
Areas where construction activities take place – for those construction activities identified in Part I.C.1.a of the
Stormwater Construction Permit (see the permit language in Section C.2, above).
In addition, other features could be included to make the SWMP a more comprehensive and usable plan. For example, a later
section of the SWMP includes requirements for material handling and spill prevention procedures, which could include a site
Water Quality Control Division – Stormwater Program www.cdphe.state.co.us/wq/permitsunit
Appendix A - Page 7 of 20 Revised 6/2011
map showing where materials are stored. By including materials handling, loading and storage areas on the site map, all
information would be in one place on a single base map. Also, including such items as site entrance(s), vehicle parking areas
and direction of stormwater flow on the site map adds to its overall utility
.
Refer to Section D of this guidance for sources of sample maps, such as the Douglas County Grading, Erosion, and Sediment
Control (GESC) Manual and the Construction Industry Compliance Assistance Center.
C.4 SWMP CONTENTS – Stormwater Management Controls
Permit
Part I.C.3 Stormwater Management Plan (SWMP) – Contents: Stormwater Management Controls
The SWMP must include a description of all stormwater management controls that will be implemented as part of the
construction activity to control pollutants in stormwater discharges. The appropriateness and priorities of stormwater
management controls in the SWMP shall reflect the potential pollutant sources identified at the facility.
The description of stormwater management controls shall address the following components, at a minimum:
This is the key part of the SWMP – a narrative description of the appropriate stormwater management controls for the
permitted site. As further addressed below, in many cases it may be necessary to supplement the narrative description with
technical drawings in order to accurately communicate the design standards for certain structural BMPs.
Permit
Part I.C.3 Stormwater Management Plan (SWMP) – Contents: SWMP Administrator
a) SWMP Administrator - The SWMP shall identify a specific individual(s), position or title who is responsible for
developing, implementing, maintaining, and revising the SWMP. The activities and responsibilities of the
administrator shall address all aspects of the facility’s SWMP.
a. SWMP Administrator: The SWMP Administrator can be an individual(s), position or title – this entity is responsible
for developing, implementing, maintaining, and revising the SWMP. Remember that the SWMP Administrator is the
contact for all SWMP-related issues and is the person responsible for its accuracy, completeness, and implementation.
Therefore, the SWMP Administrator should be a person with authority to adequately manage and direct day-to-day
stormwater quality management activities at the site.

Permit
Part I.C.3 Stormwater Management Plan (SWMP) – Contents: Identification of Potential Pollutant Sources
b) Identification of Potential Pollutant Sources - All potential pollutant sources, including materials and activities, at a
site must be evaluated for the potential to contribute pollutants to stormwater discharges. The SWMP shall identify
and describe those sources determined to have the potential to contribute pollutants to stormwater discharges, and
the sources must be controlled through BMP selection and implementation, as required in paragraph (c), below.
At a minimum, each of the following sources and activities shall be evaluated for the potential to contribute
pollutants to stormwater discharges, and identified in the SWMP if found to have such potential:
1) all disturbed and stored soils;
2) vehicle tracking of sediments;
3) management of contaminated soils;
4) loading and unloading operations;
5) outdoor storage activities (building materials, fertilizers, chemicals, etc.);
6) vehicle and equipment maintenance and fueling;
7) significant dust or particulate generating processes;
8) routine maintenance activities involving fertilizers, pesticides, detergents, fuels, solvents, oils, etc.;
9) on-site waste management practices (waste piles, liquid wastes, dumpsters, etc.);
10) concrete truck/equipment washing, including the concrete truck chute and associated fixtures and equipment;
11) dedicated asphalt and concrete batch plants;
12) non-industrial waste sources such as worker trash and portable toilets; and
13) other areas or procedures where potential spills can occur.
b. Identification of Potential Pollutant Sources: The first thing to do is evaluate all pollutant sources and activities at
the site for the potential to contribute pollutants to stormwater discharges. Part I.C.3.b of the Stormwater Construction
Permit (see permit language above) lists 13 pollutant sources that must be evaluated for the reasonable potential to
contribute pollutants to runoff. During the evaluation, consider the following types of conditions that might affect the
potential for a pollutant source to contribute pollutants to stormwater:
the frequency of the activity (i.e., does it occur every day, or just once a month; can it be scheduled to occur only
during dry weather?);
characteristics of the area where the activity takes place, e.g., area, surface type (pavement, gravel, vegetation, etc.),
and physical characteristics such as site gradients and slope lengths;
ability of primary and secondary containment (fuel tanks, drum storage, etc.) at product storage and loading/unloading
facilities to prevent and contain spills and leaks;
proximity of product storage and loading/unloading facilities to waterways or drainage facilities;
concentration and toxicity of materials which may to be found in the site's stormwater runoff
contamination of storage facilities/containment with stored materials (e.g., used oil drums or tanks coated with spilled
oil)
Each pollutant source recognized through this process as having the potential to contribute pollutants to stormwater, must
be identified in the SWMP along with the specific stormwater management control (BMPs) that will be implemented to
adequately control the source. Note: the actual evaluation of the potential pollutant sources does NOT need to be
included in the SWMP – just the resultant pollutant sources and their associated BMPs.

Permit
Part I.C.3 Stormwater Management Plan (SWMP) –
c) Best Management Practices (BMPs) for Stormwater Pollution Prevention - The SWMP shall identify and describe
appropriate BMPs, including, but not limited to, those required by paragraphs 1 through 8 below, that will be
implemented at the facility to reduce the potential of the sources identified in Part I.C.3.b to contribute pollutants to
stormwater discharges. The SWMP shall clearly describe the installation and implementation specifications for each
BMP identified in the SWMP to ensure proper implementation, operation and maintenance of the BMP.
1) Structural Practices for Erosion and Sediment Control. The SWMP shall clearly describe and locate all
structural practices implemented at the site to minimize erosion and sediment transport. Practices may include,
but are not limited to: straw bales, wattles/sediment control logs, silt fences, earth dikes, drainage swales,
sediment traps, subsurface drains, pipe slope drains, inlet protection, outlet protection, gabions, and temporary
or permanent sediment basins.
2) Non-Structural Practices for Erosion and Sediment Control. The SWMP shall clearly describe and locate, as
applicable, all non-structural practices implemented at the site to minimize erosion and sediment transport.
Description must include interim and permanent stabilization practices, and site-specific scheduling for
implementation of the practices. The SWMP should include practices to ensure that existing vegetation is
preserved where possible. Non-structural practices may include, but are not limited to: temporary vegetation,
permanent vegetation, mulching, geotextiles, sod stabilization, slope roughening, vegetative buffer strips,
protection of trees, and preservation of mature vegetation.
3) Phased BMP Implementation. The SWMP shall clearly describe the relationship between the phases of
construction, and the implementation and maintenance of both structural and non-structural stormwater
management controls. The SWMP must identify the stormwater management controls to be implemented during
the project phases, which can include, but are not limited to, clearing and grubbing; road construction; utility
and infrastructure installation; vertical construction; final grading; and final stabilization.
4) Materials Handling and Spill Prevention. The SWMP shall clearly describe and locate all practices implemented
at the site to minimize impacts from procedures or significant materials (see definitions at Part I.E.) that could
contribute pollutants to runoff. Such procedures or significant materials could include: exposed storage of
building materials; paints and solvents; fertilizers or chemicals; waste material; and equipment maintenance or
fueling procedures.
Areas or procedures where potential spills can occur must have spill prevention and response procedures
identified in the SWMP.
5) Dedicated Concrete or Asphalt Batch Plants. The SWMP shall clearly describe and locate all practices
implemented at the site to control stormwater pollution from dedicated concrete batch plants or dedicated
asphalt batch plants covered by this certification.
6) Vehicle Tracking Control. The SWMP shall clearly describe and locate all practices implemented at the site to
control potential sediment discharges from vehicle tracking. Practices must be implemented for all areas of
potential vehicle tracking, and can include: minimizing site access; street sweeping or scraping; tracking pads;
graveled parking areas; requiring that vehicles stay on paved areas on-site; wash racks; contractor education;
and/or sediment control BMPs, etc.

Part I.C.3 Stormwater Management Plan (SWMP) –
7) Waste Management and Disposal, Including Concrete Washout.
i) The SWMP shall clearly describe and locate the practices implemented at the site to control stormwater
pollution from all construction site wastes (liquid and solid), including concrete washout activities.
ii) The practices used for concrete washout must ensure that these activities do not result in the contribution
of pollutants associated with the washing activity to stormwater runoff.
iii) Part I.D.3.c of the permit authorizes the conditional discharge of concrete washout water to the ground.
The SWMP shall clearly describe and locate the practices to be used that will ensure that no washout
water from concrete washout activities is discharged from the site as surface runoff or to surface waters.
8) Groundwater and Stormwater Dewatering.
i) The SWMP shall clearly describe and locate the practices implemented at the site to control stormwater
pollution from the dewatering of groundwater or stormwater from excavations, wells, etc.
ii) Part I.D.3.d of the permit authorizes the conditional discharge of construction dewatering to the ground.
For any construction dewatering of groundwater not authorized under a separate CDPS discharge permit,
the SWMP shall clearly describe and locate the practices to be used that will ensure that no groundwater
from construction dewatering is discharged from the site as surface runoff or to surface waters.
.
c. Best Management Practices (BMPs) for Stormwater Pollution Prevention
i) Selecting and locating appropriate BMPs: When selecting BMPs, consider first those that limit the source of the
pollutant. It is much more efficient, from both a cost and environmental standpoint, to prevent the pollution in the first
place than to clean up polluted stormwater. For example, mulching disturbed ground to reduce erosion, in most cases,
is easier and more effective than trying to capture and treat sediment-laden runoff before it reaches State waters.
ii) Specific BMPs for Material Handling and Spill Prevention: Where materials can impact stormwater runoff,
existing and planned practices that reduce the potential for pollution must be described. For example, materials
should be stored and handled in covered areas to prevent contact with stormwater, and chemicals should be stored
within berms or other secondary containment devices to prevent leaks and spills from contacting stormwater runoff.
In general, spill prevention and response procedures should include the following:
notification procedures to be used in the event of an accident. At the very least, the SWMP Administrator should
be notified. Depending on the nature of the spill and the material involved, the Colorado Department of Public
Health and Environment (24-hour spill reporting line – 877-518-5608), downstream water users, or other agencies
may also need to be notified;
instructions for clean-up procedures, and identification of spill kit location(s);
provisions for absorbents to be made available for use in fuel areas, and for containers to be available for used
absorbents; and
procedures for properly washing out concrete truck chutes and other equipment in a manner and location so that
the materials and wash water can not discharge from the site, and never into a storm drain system or stream.
Once source reduction BMPs have been evaluated, more costly options, such as mitigation of impacts or stormwater
treatment through detention storage, must be considered as necessary. The selection of BMPs is subject to the
judgment of the individual permittee, based on the conditions at the site. It is important to keep in
Water Quality Control Division – Stormwater Program www.cdphe.state.co.us/wq/permitsunit
Appendix A - Page 11 of 20 Revised 6/2011
mind that BMPs included in the SWMP and 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. Therefore, in order to comply with your permit terms and conditions, appropriate practices must be
implemented in keeping with the pollutant(s) involved and the risk potential at the facility. Redundant BMP use is
highly recommended to eliminate reliance on any one (or two) BMPs, and is often necessary to provide an adequate
treatment train to remove pollutants in runoff.
In addition, the BMPs selected for use must be appropriately designed and implemented, following good engineering
practices. It is best to base BMP design and implementation on professionally accepted references. Many well-
accepted references are available that include guidance on proper BMP selection, design, and implementation. Some
counties, cities, and local agencies have adopted criteria manuals for stormwater BMPs. Section D.1 of this guidance
contains a discussion of additional resources for more in-depth information on stormwater quality BMPs.
BMP location
A permittee must ensure that BMPs implemented to control stormwater pollution are located prior to the stormwater
discharge to a receiving water or a stormwater collection system. To meet this condition, BMPs may be implemented at
any location that allows for adequate treatment of stormwater pollutants, as long as all of the following criteria are met:
All BMPs are located:
o prior to the stormwater leaving the control of the permittee, i.e., where the permittee is capable of ensuring the
BMPs‘ proper operation and maintenance (see below section on Ensuring BMPs);
o prior to discharge to a receiving water defined as Waters of the United States (see below section on Protecting
Waters of the US); and
o prior to discharge into a municipal storm sewer or other stormwater collection system not owned by the
permittee (unless specific permission is granted).
BMPs are implemented to control all pollutant sources covered by the permit certification (i.e., unmanaged pollutant
sources are not located down slope from the last BMP at a site).
BMPs are implemented in accordance with the site‘s SWMP.
Although it is acceptable, and often advisable when used in conjunction with redundant BMPs, to locate structural BMPs
in areas of concentrated flow (e.g., check dams along drainage ditches, detention ponds, etc.), remember that removing
sediment from stormwater is often not as efficient a practice as preventing erosion in the first place, and that once erosion
starts, additional sediment control BMPs will almost always be necessary to prevent the discharge of sediment from the
site. The most efficient construction site BMPs are those that prevent erosion from occurring.
Ensuring BMPs are under the Control of the Permittee
If a permittee will rely on contracts or agreements with other entities to manage BMPs (e.g., when BMPs will be located
off of the permittee‘s property and implemented by a second party, such as a site developer), the guidance found in Part
G.2.b of the Stormwater Fact Sheet—Construction (available from the Division‘s web site at
www.cdphe.state.co.us/wq/PermitsUnit) must be followed to ensure the BMPs are properly addressed in the SWMP and
implemented in the field. A permittee may not rely on a BMP owned or operated by a second party if the permittee does
not have permission to use the BMP, and/or if they do not have any agreements in place to ensure its adequate operation
and maintenance in accordance with the permittee‘s SWMP.
Protecting Waters of the United States
BMPs must not be located within waterways, including wetlands, that are defined as Waters of the United States, unless
specifically authorized by and in compliance with a separate 404 permit (also referred to as Dredge and Fill permits)
from the U.S. Army Corps of Engineers. Even when BMPs may be authorized in natural waterways, such BMPs are
only intended to control pollutants originating from activities within the waterway, and additional BMPs are still
necessary to prevent sediment from the remainder of the site from entering that waterway. Note that even if a drainage
has been modified by a private or municipal entity, it still may be considered Waters of the United States. It is the owner
and/or operator‘s responsibility, through consultation with the Army Corps of Engineers, to confirm the existence of any
Waters of the United States at their site. More information on 404 permitting, including regional office contact
information, may be obtained from the Army Corps of Engineers regulatory programs‘ web page at

iii) Documenting Selected BMPs in the SWMP (including phasing of BMP implementation): The SWMP must
describe the specific stormwater management controls (BMPs) that will be implemented at the site to adequately
control each identified pollutant source (see Section C.4.b, above). Estimated dates for BMP implementation and
maintenance are required, and any existing controls must also be discussed. The plan shall identify both structural and
non-structural control measures that are necessary for erosion and sediment control at the site. Thoroughly describe
how the BMP used at the site will change with the different stages of construction activity at the site, and make sure
that BMPs implemented for dedicated concrete or asphalt batch plants, if applicable, and vehicle tracking controls, are
clearly documented.
BMP description: Level of detail
BMP descriptions provided in the SWMP must contain adequate detail to ensure proper implementation at the site. The
following information must be addressed in the SWMP:
What BMPs will be implemented?
When will the BMPs be implemented? Many BMPs will only be implemented during specific phases of the project.
For example, silt fence and detention ponds may be installed prior to grading, while inlet protection for a newly
constructed stormwater collection system will need to be installed upon completion of the inlets.
Where will the BMPs be implemented? The SWMP must clearly indicate the locations where BMPs will be
implemented. For structural BMPs, this will usually require including the locations on the site map discussed in
Section C.3 above.
How will the BMPs be implemented? The installation and implementation specifications included in the SWMP
must be sufficient to ensure proper implementation, including procedures for operation and maintenance of the
BMP. For structural BMPs, in most cases this must include a technical drawing. For example, if silt fence will be
used at a site, in addition to the timing and location of installation, the SWMP must provide information such as
trenching depth, stake spacing, materials, etc. BMP installation and implementation criteria must follow good
engineering practices. Although it is not necessary to include design calculations in the SWMP, such as those used
to determine pond capacity or slope limitations for silt fence, this information may be useful to include to assist in
proper revisions to the SWMP and site BMPs if and when necessary, as discussed below.
iv) Non-Stormwater Discharges: Except for emergency fire fighting activities, landscape irrigation return flow,
uncontaminated springs, construction dewatering and concrete wash out water, the Stormwater Construction Permit
only covers discharges composed entirely of stormwater.
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 specific conditions, may be allowed
by the Stormwater Construction Permit when appropriate BMPs are implemented. Additional information on this
subject is available in the Stormwater Fact Sheet – Construction, available from the Division‘s web site at
www.cdphe.state.co.us/wq/PermitsUnit.
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 specific conditions,
may be allowed by the Stormwater Construction Permit when appropriate BMPs are implemented. Additional
information on this subject is available in the Stormwater Fact Sheet – Construction, available from the Division‘s
web site at www.cdphe.state.co.us/wq/PermitsUnit.
Water Quality Control Division – Stormwater Program www.cdphe.state.co.us/wq/permitsunit
Appendix A - Page 13 of 20 Revised 6/2011
Aside from the exceptions noted above, non-stormwater discharges must be addressed in a separate permit issued for
that discharge. Contact the Division or visit our web page at www.cdphe.state.co.us/wq/PermitsUnit for guidance and
applications.
v) Stormwater Dewatering: The discharge of pumped stormwater, only, from excavations, ponds, depressions, etc.,
to surface waters, or to a municipal separate storm-sewer system (MS4) is allowed by the Stormwater Construction
Permit, as long as the dewatering activity and associated BMPs are identified in the SWMP (including location of the
activity), and BMPs are implemented in accordance with the SWMP.
Note: Pumping stormwater does not by itself render the pumped water a process water, provided that the pump does
not contribute additional pollutants to the discharge. If, however, a sheen is visible on the water leaving the pump, a
separate discharge permit is required.
d. Revising BMPs and the SWMP: At nearly every site, the implemented BMPs will have to be modified to adapt to
changing site conditions, or to ensure that potential pollutants are consistently and properly managed. The pollutant
sources and management practices at a site must be reviewed on an ongoing basis (and specifically during the required
inspections listed in Part I.D.6 of the Stormwater Construction Permit and discussed below). When BMPs or other site
conditions change, the SWMP must be modified to accurately reflect the actual field conditions. Examples include,
but are not limited to, removal of BMPs, identification of new potential pollutant sources, addition of BMPs, modification
of BMP installation and implementation criteria or maintenance procedures, and changes in items included in the site map
and/or description. SWMP revisions must be made prior to changes in site conditions, except for Responsive SWMP
Changes, as follows:
– SWMP revisions must be made immediately after changes are made in the field to address BMP installation
and/or implementation issues; or
– SWMP revisions must be made as soon as practicable, but in no case more than 72 hours, after change(s) in
BMP installation and/or implementation occur at the site that require development of materials to modify the
SWMP (e.g., design of retention pond capacity)
The SWMP should be viewed as a ―living document‖ that is continuously being reviewed and modified as part of the
overall process of assessing and managing stormwater quality issues at the site. The following illustration summarizes the
process of evaluating, selecting, documenting, implementing, and revising BMPs.

C.5 SWMP CONTENTS – Final Stabilization and Long-term Stormwater Management
Permit
Part I.C.4 Stormwater Management Plan (SWMP) – Contents: Final Stabilization and Long-term Stormwater
Management
a) The SWMP shall clearly describe the practices used to achieve final stabilization of all disturbed areas at the site, and
any planned practices to control pollutants in stormwater discharges that will occur after construction operations
have been completed at the site.
b) Final stabilization practices for obtaining a vegetative cover should include, as appropriate: seed mix selection and
application methods; soil preparation and amendments; soil stabilization practices (e.g., crimped straw, hydro mulch
or rolled erosion control products); and appropriate sediment control BMPs as needed until final stabilization is
achieved; etc.
c) Final stabilization is reached 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.
The Division may, after consultation with the permittee and upon good cause, amend the final stabilization criteria in this
section for specific operations.
Typically, the stormwater discharges associated with construction activity are eliminated when the site is finally stabilized. As
soon as practicable after construction activities have been completed in a disturbed area, permanent stabilization should be
started to prevent further erosion of soil from that area. All disturbed areas (except those portions covered by pavement or a
structure) must be finally stabilized once all construction activities are completed in order to inactivate the permit coverage.
Sediment that collects within the site's drainage system and permanent water quality or quantity controls is also considered
unstabilized soil, and must be removed prior to the site being considered finally stabilized.
The SWMP must include a description of what measures will be taken to finally stabilize the site. The method of stabilization
must be provided for all areas that will remain pervious (i.e., vegetated or landscaped instead of paved, built on, or otherwise
structurally stabilized). Questions that may need to be addressed include: What type of cover will be used? What are the
specific seed mixtures and application rates? Are additional BMPs needed to prevent erosion as the vegetation becomes
established? Will the soil need to be amended? Will special methods be employed on any steep slopes or areas of
concentrated flow?
Inactivation of permit coverage
Coverage under the Stormwater Construction Permit may be inactivated by the permittee when the site has attained final
stabilization, all temporary erosion and sediment control measures have been removed, and all components of the
SWMP are complete.
Any planned stormwater management controls to prevent or control pollution of stormwater after construction is completed
must be addressed here. They typically include retention or detention ponds, infiltration measures, vegetative swales, and
natural depressions.
New developments, buildings, etc., will often incorporate elements of permanent stormwater quality control into their design.
The SWMP must be prepared consistent with these structural and nonstructural controls. Where possible, permanent
stormwater quality controls can be constructed at the initial stages of construction, or modified at the end of construction. This
can increase the efficiency of the controls by using them during both the building and operational phases of the project. When
a permanent structural control is initially used as a construction BMP, the SWMP must contain the necessary information
discussed in the guidance for documenting BMPs, Section C.4 above.
Water Quality Control Division – Stormwater Program www.cdphe.state.co.us/wq/permitsunit
Appendix A - Page 15 of 20 Revised 6/2011
Use of Permanent Detention Ponds as BMPs during Construction
Permanent detention ponds are allowed to be used as a temporary construction BMP, if: a) the pond is clearly designated
as a construction BMP in the SWMP; b) detention pond inspection and maintenance are described as required in Part
I.B.2, Part I.C.3, and Parts I.D.6, 7, and 8 of the Stormwater Construction Permit; and c) the pond is designed and
implemented for use as a BMP during construction in accordance with good engineering, hydrologic and pollution
control practices. In addition, stormwater discharges from the pond must not cause or threaten to cause pollution or
degradation of State waters. When a permanent detention pond is used in this manner, redundant upgradient erosion and
sediment control BMPs are still necessary in almost all cases to comply with the permit requirements to select and design
BMPs to prevent pollution or degradation of State waters.
The design and implementation of the pond may differ from what will exist upon completion of the project when the
BMP becomes a permanent water quality feature. In this case, the description of the BMP included in the SWMP must
address these differences. For example, if the outfall will be modified during construction to provide additional filtering
or settling of sediment (which may or may not be necessary, depending on the existence of upstream BMPs, sediment
loading to the pond, final outlet design, etc.), those modifications must be included in the SWMP. If additional
temporary stabilization of the pond (e.g., at points of concentrated flow into or through the pond, unstable slopes, etc.) is
needed to prevent erosion and transport of sediment from the pond during construction, this must also be addressed.
Prior to inactivation of the permit, the pond must be stabilized in accordance with the permit requirements and sediment
removed from the site‘s drainage system. Although not related to compliance with the construction stormwater permit,
the pond may need to be inspected and modified following construction in order to meet local permanent BMP design
criteria.
C.6 SWMP CONTENTS – Inspection and Maintenance Procedures
Permit
Part I.C.5. Stormwater Management Plan (SWMP) – Contents: - Inspection and Maintenance
Part I.D.6 of the permit includes requirements for site inspections. Part I.D.7 of the permit includes requirements for BMP
maintenance. The SWMP shall clearly describe the inspection and maintenance procedures implemented at the site to
maintain all erosion and sediment control practices and other protective practices identified in the SWMP, in good and
effective operating condition.
a. Inspection Schedules: The minimum inspection schedule described in Part I.C.6.a of the Stormwater Construction
Permit requires that a thorough inspection of the stormwater management system be performed and documented at least
every 14 days, and within 24 hours of any precipitation or snowmelt event that causes surface erosion (i.e., that results in
stormwater running across the ground). If more frequent inspections are required to ensure that BMPs are properly
maintained and operated, the inspection schedule must be modified to meet this need.
Exceptions to the minimum inspection schedule are also provided. Any use of an exception is temporary, and does not
eliminate the requirement to perform routine maintenance due to the effects of a storm event or other conditions that may
impact BMP performance, including maintaining vehicle tracking controls and removing sediment from impervious areas.
Additionally, this part of the SWMP must also include maintenance procedures for the BMPs, as discussed below. You
will need to set up a schedule appropriate to the activity and the BMP. Preventive maintenance should be coupled with
periodic inspections.
b. Inspection Procedures: The inspection must include observation of:
the construction site perimeter and discharge points (including discharges into a storm sewer system);
all disturbed areas;
areas used for material/waste storage that are exposed to precipitation;
Water Quality Control Division – Stormwater Program www.cdphe.state.co.us/wq/permitsunit
Appendix A - Page 16 of 20 Revised 6/2011
other areas determined to have a significant potential for stormwater pollution, such as demolition areas or concrete
washout locations, or locations where vehicles enter or leave the site;
erosion and sediment control measures identified in the SWMP; and
any other structural BMPs that may require maintenance, such as secondary containment around fuel tanks, or the
condition of spill response kits.
The inspection must determine if there is evidence of, or the potential for, pollutants entering the drainage system. BMPs
should be reviewed to determine if they still meet the design and operational criteria in the SWMP, and if they continue to
adequately control pollutants at the site. Any BMPs not operating in accordance with the SWMP must be addressed as
soon as possible, immediately in most cases, to minimize the discharge of pollutants, and the SWMP must be updated as
described in Section C.4.e, above. Inspections must be documented as discussed in the Record Keeping section, below.
c. BMP Maintenance/Replacement and Failed BMPs: The Stormwater Construction Permit requires that all erosion
and sediment control practices and other protective measures identified in the SWMP be maintained in effective operating
condition and in accordance with good engineering, hydrologic and pollution control practices. Therefore, site inspection
procedures must address maintenance of BMPs that are found to no longer function as needed and designed, as well as
preventive maintenance to proactively ensure continued operation (e.g., removing collected sediment outside the
acceptable tolerances of the BMP).
A preventive maintenance program should prevent BMP breakdowns and failures by proactively maintaining or replacing
BMPs and equipment. Site inspections should uncover any conditions, such as deteriorating silt fence or water collected
in fuel tank secondary containment, which could result in the discharge of pollutants to storm sewers and surface waters.
For example, sediment that has been collected by sediment controls, such as silt fence and inlet protection, should be
removed on a regular basis, to prevent failure of BMPs, and remove the potential of that sediment from being discharged
from the site if the BMP did fail. Removed sediment must be moved to an appropriate location where it will not become
an additional pollutant source, and should never be placed in ditches or streams. Maintenance activities to correct
problems noted during inspections must be documented as discussed in the Record Keeping section, below.
The inspection process must also include procedures to ensure that, when needed, BMPs are replaced or new BMPs added
to adequately manage the pollutant sources at the site. This procedure is part of the ongoing process of revising the BMPs
and the SWMP as discussed Section C.4, above, and any changes to BMPs must be recorded in the SWMP. The SWMP
must be modified as appropriate as soon as practicable after such inspections.
BMPs that have failed, or have the potential to fail without maintenance or modifications, must be addressed as soon as
possible, immediately in most cases, to prevent the discharge of pollutants.
d. Record Keeping and Documenting Inspections: Keeping accurate and complete records serves several functions.
First, keeping records of spills, leaks, inspections, etc. is a requirement of the Stormwater Construction Permit; therefore,
enforcement action, including fines, could result if records are not adequate. Second, by keeping accurate and detailed
records, you will have documentation of events which could prove invaluable should complications arise concerning the
permit, lawsuits, etc.
The permittee must document inspection results and maintain a record of the results for a period of 3 years following
expiration or inactivation of permit coverage. These records must be made available to the Division or EPA upon request.
The following items must be documented as part of the site inspections:
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 Section C.6.a above;
viii) Description of corrective action for items iii, iv, v, and vi, above, dates corrective action(s) taken, and measures
Water Quality Control Division – Stormwater Program www.cdphe.state.co.us/wq/permitsunit
Appendix A - Page 17 of 20 Revised 6/2011
taken to prevent future violations, including requisite changes to the SWMP, as necessary; and
ix) 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.
In addition to inspection records, the permittee may opt to keep a log book for use in tracking other items related to the
SWMP such as those listed below. Additional information such as dated photographs, field notebooks, drawings and
maps, and the items below, etc. can also be included where appropriate.
BMP operation and maintenance
stormwater contamination
contacts with suppliers
notes on the need for and performance of preventive maintenance and other repairs
implementation of specific items in the SWMP
training events (given or attended)
events involving materials handling and storage
contacts with regulatory agencies and personnel
notes of employee activities, contact, notifications, etc.
Records of spills, leaks, or overflows that result in the discharge of pollutants must be documented and maintained. You
may also want to record other spills that are responded to, even if they do not result in a discharge of pollutants.
Information that should be recorded for all occurrences includes the time and date, weather conditions, reasons for the
spill, etc. Some spills may need to be reported to the Division immediately. Specifically, a release of any chemical, oil,
petroleum product, sewage, etc., which may enter waters of the State of Colorado (which include surface water, ground
water and dry gullies or storm sewers leading to surface water) must be reported. More guidance is available on the web at
www.cdphe.state.co.us/hm/spillsandreleases.htm. The Division‘s toll-free 24-hour number for environmental hazards and
chemical spills and releases is 1-877-518-5608.
D. ADDITIONAL SWMP AND BMP RESOURCES
There are a multitude of resources available to the construction industry to assist in complying with the requirements of the
Stormwater Construction Permit. The following suggested list of resources can provide valuable tools to assist you in
developing and implementing your SWMP as effectively and efficiently as possible. However, the guidance found in the
resources listed below in no way replaces the requirements of the Stormwater Construction Permit, as described in Sections A
through C, above. Therefore, when using the following resources, especially in the case of example plans and maps, it is
essential that you ensure that all of the requirements included in this guidance document and the Stormwater
Construction Permit are being met.
Many of the resources below require access to the internet. If you are unable to obtain any resources you need due to a lack of

WATER RIGHTS
The State Engineers Office (SEO) has indicated that any discharge that does not return water directly to surface
waters (i.e.land application, rapid infiltration basins, etc.) has the potential for material injury to a water right. As a
result, the SEO needs to determine that material injury to a water right will not occur from such activities. To make
this judgment, the SEO requests that a copy of all documentation demonstrating that the requirements of Colorado
water law have been met, be submitted to their office for review. The submittal should be made as soon as possible
to the following address:
Colorado Division of Water Resources
1313 Sherman Street, Room 818
Denver, Colorado 80203
Should there be any questions on the issue of water rights, the SEO can be contacted at (303) 866-3581. It is
important to understand that any CDPS permit issued by the Division does not constitute a water right. The issuance
of a CDPS permit does not negate the need to also have the necessary water rights in place. Additionally, if the
activity has an existing CDPS permit, there is no guarantee that the proper water rights are in place.
I. Required Certification Signature [Reg 61.4(1)(h)]
"I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in
accordance with a system designed to assure that qualified personnel properly gather and evaluate the information
submitted. Based on my inquiry of the person or persons who manage the system, or those persons directly responsible for
gathering the information, the information submitted is to the best of my knowledge and belief, true, accurate and
complete. I am aware that there are significant penalties for submitting false information, including the possibility of fine
and imprisonment for knowing violations."
―I understand that submittal of this application is for coverage under the State of Colorado General Permit for Discharges
Associated with Construction Dewatering for the entirety of the construction site/project described and applied for,
until such time as the application is amended or the certification is transferred, inactivated, or expired.‖

obtained from a variety of sources, including:
Various Websites: http://terraserver.microsoft.com, http://geocoder.us/, or
www.epa.gov/tri/reports/siting_tool/index.htm
U.S Geological Survey topographical map, available at area map stores
Surveyors or engineers for the construction project should have, or be able to calculate this information using a
Global Positioning System (GPS) unit
Specify whether the Latitude/Longitude information was collected either by using a GPS unit or through Map interpolation.
3. Facility Activity and Schedule: Include the anticipated start date of construction dewatering and provide the length of
time dewatering is anticipated to last. Provide a description of the general nature of the construction activities that are
requiring the dewatering. Also describe if the dewatering discharge is from an open excavation, such as a trench or foundation,
or from groundwater lowering wells. Examples of activity descriptions may include: ‗open trench excavation for installation
of 4,000 linear feet of new water lines‘, or ‗a series of shallow groundwater wells will be installed around the perimeter of the
construction site in order to lower the water table for construction of a new 5,000 square foot music shop—all wells will be
piped to one manifold resulting in one discharge location as indicated on our site sketch.
4. Discharges to ditches and storm sewers: Indicate by checking yes or no whether or not the immediate effluent will be
discharged to a ditch or storm sewer. If yes is marked, the applicant must contact the owner of the ditch or storm sewer
system prior to discharge to verify if the owner will allow a discharge to their system. The owner of the ditch/storm sewer
system may impose additional requirements. Storm drainage systems are typically owned by the city or county they are located
within, and therefore contacting the local city/county is the appropriate place to start. If yes is marked, in Table C or Table D
be sure to include the location of the system and the ultimate receiving waters.
5. Defined or Undefined Discharge: Identify whether the applicant is applying for a Defined or Undefined discharge.
A Defined Discharge is a discharge where the dewatering discharge locations are known at the time of permit application.
If discharge is Defined – enter discharge information in Table C
Page 1 of 3—Revised April 2011
Industrial Wastewater Discharge Permit – Construction Dewatering www.coloradowaterpermits.com
An Undefined Discharge is a discharge where the exact dewatering discharge locations are unknown at the time of permit
application. The permit applicant must request the maximum number of potential outfalls (discharges) for the permitted
facility/project. If discharge is Undefined – enter discharge information in Table D. The applicant must identify all
potential receiving streams for the entire project.
If the applicant is requesting undefined discharges, the site specific sampling and monitoring parameters will be selected
based on the potential pollutant sources found within the entire permitted project area and will be applied to all outfall(s).
The most stringent of the surface water limitations for each identified site specific parameter will be applied to each
permitted outfall. For example, if the undefined project includes installation of 8 miles of linear pipeline and leaking
underground storage tanks are expected to present in one section of the project, sampling and monitoring for Benzene,
Toluene, Ethyl benzene, and Xylenes will be required for all requested outfall(s).
Item C- Information for Defined Discharge Location(s).
1. If Defined Discharge was marked in Section B.5 fill out Table C. Table C requires the following information:
Number of discharge(s) (outfalls)—Identify the number of outfalls requested in Table C, this includes
discharges to surface water and groundwater. If there are more than two requested discharges to surface water,
