SWMP Template REV April 2019 Page 1
SECTION 1: INTRODUCTION
1.1 Overview
In 1972, Congress passed the Federal Water Pollution Control Act (FWPCA), also known as the Clean Water Act
(CWA), to restore and maintain the quality of the nation’s waterways. The ultimate goal was to ensure that rivers
and streams were fishable, swimmable, and drinkable. In 1987, the Water Quality Act (WQA) added provisions to
the CWA that allowed the EPA to govern stormwater discharges from construction sites.
The Construction General Permit (CGP) authorizes stormwater discharges from large and small construction
activities that result in a total land disturbance of equal to or greater than one acre, where those discharges enter
surface waters of the United States or a municipal separate storm sewer system (MS4) leading to surface waters
of the United States subject to the conditions set forth in the permit. The permit replaces two permits issued in
1998 (63 FR 7858, February 17, 1998 for EPA Regions 1, 2, 3, 7, 8, 9, and 10 and 63 FR 36489, July 6, 1998 for
EPA Region 6).
The National Pollutant Discharge Elimination System (NPDES) Stormwater Program regulates stormwater
discharges from three potential sources: municipal separate storm sewer systems (MS4s), construction activities,
and industrial activities. Most stormwater discharges are considered point sources, and operators of these
sources may be required to receive an NPDES permit before they can discharge. This permitting mechanism is
designed to prevent stormwater runoff from washing harmful pollutants into local surface waters such as streams,
rivers, lakes or coastal waters.
The EPA has delegated authority to the State of Colorado to manage their own National Pollutant Discharge
Elimination System (NPDES) in all areas of the state excluding Indian country and Federal Facilities as defined in
the State’s Construction General Permit.
1.2 Purpose
The Stormwater Management Plan (SWMP) includes, but is not limited to, this SWMP with appendices, the
Erosion and Sedimentation Control Plan included in the Construction Drawings (Site Maps) with the Detail Sheet,
the Notice of Intent, Transfer forms, Permit Authorization, General Permit, Notice of Termination (NOT), all
records of inspections and activities which are created during the course of the project, and other documents as
may be included by reference to this SWMP. Changes, modifications, revisions, additions, or deletions shall
become part of this SWMP as they occur.
The goal of pollution prevention efforts during project construction is to control soil and pollutants that originate on
the site and prevent them from flowing to surface waters. The purpose of this SWMP is to provide guidelines for
achieving that goal. A successful pollution prevention program also relies upon careful inspection and
adjustments during the construction process in order to enhance its effectiveness.
The Contractor’s participation in this program is mandatory and its non-compliance is subject to various remedies,
including without limitation, monetary set-offs, withholding payments; reimbursement for costs, expenses
(including reasonable attorney’s fees), fines, and civil penalties incurred by Kum & Go; and/or liquidated damages
as set forth in the Contractor’s contract with Kum & Go. The Owner referred to in this SWMP is Kum & Go, L.C.
The General Contractor shall construct the site development improvements while working under contract with the
Owner.
1.3 Scope
This SWMP, including the applicable General Permit, includes the elements necessary to comply with the
General Permit for construction activities administered by the U.S. Environmental Protection Agency (EPA) under
the National Pollutant Discharge Elimination System (NPDES) program and all local governing agency
requirements. This SWMP must be implemented at the start of construction.
Stormwater Management Plan (SWMP)
Kum & Go Store #0951
SWMP Template REV April 2019 Page 2
Construction phase pollutant sources anticipated at the site are disturbed (bare) soil, vehicle fuels and lubricants,
chemicals and coatings associated with site or building construction and pavement installation, construction-
generated litter and debris, and building materials. Without adequate control there is a potential for each type of
pollutant to be transported by stormwater.
The General Contractor and all subcontractors involved with a construction activity that disturbs site soil or who
implement a pollutant control measure identified in the SWMP, or otherwise required, must comply with the
following requirements of the National Pollutant Discharge Elimination System (NPDES) General Permit per the
delegated governing agency having jurisdiction concerning NPDES, stormwater, erosion, and sedimentation
control:
A. NOTICE OF INTENT: The Owner and Operator will petition the Colorado Department of Public Health
and Environment (CDPHE) for stormwater discharges during construction at this site to be covered by the
CDPS General Permit Stormwater Discharges Associated with Construction Activity Authorization to
Discharge Under the Colorado Discharge Permit System (CDPS) following completion of this SWMP. An
NOI (using the form required by the federal, state, and/or local permitting agency), to be covered under
this permit, will be filed by the Operator, if required. Authorization to discharge stormwater from
Construction Activities is effective upon receipt of permit authorization by the state environmental agency.
The SWMP must be prepared prior to submittal of the NOI. It is the Contractor’s obligation to verify with
the state agency if it will be authorized under the Operator’s permit or if a separate permit will be required.
1. The NOI shall be signed by Ryan Halder, SVP of Store Development, Kum & Go, L.C and an
appropriate representative of the Operator with signatory authority.
B. RESPONSIBILITIES OF CONTRACTOR REGARDING THE CONSTRUCTION GENERAL PERMIT:
The Contractor shall manage the discharge of stormwater from the site in accordance with the CDPS
General Permit Stormwater Discharges Associated with Construction Activity Authorization to Discharge
Under the Colorado Discharge Permit System (CDPS) conditions and the following provisions:
1. The Contractor shall be responsible for conducting the Stormwater Management practices in
accordance with the permit.
2. The Contractor shall be responsible for providing Qualified Stormwater Managers (See Section 1.3
(F) for description) to conduct the inspections required by the SWMP.
3. The Contractor shall be responsible for any enforcement action taken or imposed by federal, state,
or local agencies, including the cost of fines, construction delays, and remedial actions resulting from
the Contractor’s failure to comply with the permit provisions.
4. It shall be the responsibility of the Contractor to make any changes to the SWMP necessary in order
to comply with applicable laws and regulations or with any updating and modification requirements
discussed in this SWMP when the Contractor or any of his subcontractors elects to use borrow or fill
or material storage sites, either contiguous to or remote from the construction site, when such sites
are used solely for the Project. Such sites are not considered to be part of the Project covered by the
permit and this SWMP. Off-site borrow and/or fill sites which are used for the Project must be
operating under an approved permit from the jurisdictional entity. The Contractor must provide
location and permit number of approved off-site borrow/fill sites in the SWMP Ledger. The
Contractor should consider this requirement in negotiating with earthwork subcontractors, since the
choice of an off-site borrow, fill, or material storage site may impact their duty to implement, make
changes to, and perform inspections required by the SWMP for the site.
5. This SWMP intends to control water-borne and liquid pollutant discharges by some combination of
interception, sedimentation, filtration, and containment. The General Contractor and subcontractors
implementing this SWMP must remain alert to the need to periodically refine and update the SWMP
in order to accomplish the intended goals. The General Contractor is ultimately responsible for all
site conditions and permit compliance.
C. PUBLIC POSTING (Including SWMP Information Sign)
Stormwater Management Plan (SWMP)
Kum & Go Store #0951
SWMP Template REV April 2019 Page 3
Install the Construction Site Notice at the Construction Site entrance and in the job trailer. The following
information must be readily available, upon request, near the SWMP Information Sign within the job
trailer: current Site Maps, Detail Sheets, and the SWMP Ledger for public view until termination of permit
coverage has been obtained by filing the Notice of Termination (NOT) or once the Project has reached
Final Stabilization, as required by the state agency. Reference the Construction Site Notice (See
Appendix D) detail for proper posting of documents.
D. SWMP LEDGER
One (1) copy shall be provided to the Kum & Go SDM. A copy of the SWMP Ledger with all required
certifications and record keeping forms will be e-mailed or uploaded, as required, by the Operator’s
Engineer to the SDM, when available. SWMP Ledgers shall be tabbed and indexed per the Table of
Contents. The SWMP Ledger is meant to be a working document that shall be maintained by the
Contractor at the site of the Construction Activities at all times throughout the Project and readily available
for review by the Owner, federal, state, or local officials.
The General Contractor must update the SWMP and Site Maps bi-weekly to reflect the progress of
construction activities and general changes to the project site. SWMP contact, contractor information, and
the record of site stabilization activities log must be maintained by the General Contractor throughout the
project.
CCMs that do not impact the hydraulic design of the site may be modified or added by the General
Contractor and reflected on site maps accordingly, as needs arise. Examples of CMs that do not typically
impact the hydraulic design of the site include silt fence, silt dike, wattles, vehicle tracking control, and
various forms of temporary and permanent erosion controls (blankets, nets, seed, sod, etc.). Examples of
CCMs that commonly impact hydraulic design include stormwater basins, diversions, check dams, inlet
protection or any product, process or system that changes the stormwater flow path or stormwater
storage capacity of the site or is located in an area of concentrated flow.
The General Contractor must submit a Request For Information (RFI) to the Owner’s Engineer and obtain
written approval before modifying or adding sediment controls that may impact the hydraulic design of the
site.
Substitution of any erosion or sediment control CCM, beyond those specified in the SWMP, must first be
approved in writing by the Owner’s Engineer. Substitutions are typically only approved if specified
materials are not available or there is a valid reason the specified CCM will not work.
Amending the SWMP does not mean that it has to be reprinted. It is acceptable to add addenda,
sketches, new sections, details, and/or revised drawings that are initialed and dated.
A complete copy of the SWMP Ledger, including copies of all inspection reports, plan revisions, etc., must
be retained for at least three (3) years following from the date the permit expires or the date the
permittee’s authorization is terminated, as required by the state agency.
E. SWMP CERTIFICATION REQUIREMENTS FOR THE CONTRACTOR AND SUBCONTRACTOR(S):
The General Contractor must provide names and addresses of all subcontractors working on this project
who will be involved with the major construction activities that disturb site soil or otherwise affect CCM
implementation. This information must be kept in the SWMP Ledger.
The SWMP Ledger shall provide forms for both the Contractor and Subcontractor(s) identifying the
Company Name, Business Address, and Telephone Number along with the Responsible Person for the
Contractor and all Subcontractors who will implement, maintain, impact the pollution control measures
identified in the SWMP, and/or are involved in ground-disturbing activities on the site.
The General Contractor shall sign “Contractor’s Certification” (See Section 2.1) and all Subcontractors
shall sign “Subcontractor’s Certification” (See Appendix H), verifying they have been instructed on how to
Stormwater Management Plan (SWMP)
Kum & Go Store #0951
SWMP Template REV April 2019 Page 4
comply with and fully understand the requirements of the CPDS General Construction Permit and SWMP.
These certifications must be signed, by a responsible corporate officer or other party meeting the
Signatory Requirements or “cognizant official” as defined by the CDPS General Permit Stormwater
Discharges Associated with Construction Activity Authorization to Discharge Under the Colorado
Discharge Permit SystemPart II.K.1, on behalf of each entity, prior to the beginning of any Construction
Activities and shall be filed in the SWMP Ledger.
F. INSPECTIONS: Inspections shall begin within seven (7) calendar days of the start of construction
(3/16/2022) and shall be performed at the frequency listed in Section 7.1 and shall continue until the
Notice of Termination (NOT) is filed and the site has reached Final Stabilization.
o Frequency: Refer to Section 7.1 for inspection frequency requirements.
o Procedures: Inspect all disturbed areas of the site, areas for material and equipment storage, waste
and borrow areas, locations where vehicles enter or exit the site, all of the erosion and sediment
controls that were identified as part of the plan, areas where stormwater flows within the site,
stabilized areas, and accessible discharge locations must be inspected. Where discharge locations
are inaccessible, nearby downstream locations must be inspected to the extent that such inspections
are practicable.
Inspect to see if erosion and sediment controls require maintenance, corrective action, or new control
measures are required; for the presence of conditions that could lead to spills, leaks, or other
pollutant accumulations and discharges; for visible signs of erosion and sediment accumulation at
points of discharge and to the channels and stream banks that are in the immediate vicinity of the
discharge; if stormwater discharge is occurring at the time of the inspection, whether obvious, look for
visual signs of pollutant discharges and note if any permit violations have occurred on the site.
Controls must be in good operating condition until the construction activity is complete and final
stabilization has been reached.
o Repair and/or Maintenance: Any measure found to be damaged or in need of maintenance shall be
initiated as soon as possible.
o Silt Fence shall be inspected for tears, depth of sediment, location with respect to drainage,
secured to posts, and that the posts are in place.
o All sediment control measures including silt fence, inlet protection, sediment traps and sediment
basins, if present, shall be inspected for depth of sediment, and built up sediment will be removed
when it reaches 50 percent of the design capacity.
o Temporary and permanent seeding and all other stabilization measures will be inspected for bare
spots, washouts, and healthy growth.
o Locations where vehicles enter or exit the site must be inspected for evidence of off-site tracking
and any off-site tracking cleaned up.
o Disturbed Areas and materials storage areas will be inspected for evidence of or potential for
pollutants entering stormwater systems.
The SWMP, including the best management practices implemented on the jobsite, shall be modified as
needed to reduce or prevent pollutants from discharging from the site. Modifications to CMs that change a
hydraulic design component (diversions, basins, etc.) must first be approved by the Owner’s Engineer.
o Agency Stormwater Inspections: The General Contractor must walk the site with the regulatory
inspector and document any deficiencies noted during the inspection. Deficiencies of any type, field
or documentation-related, identified during the regulatory inspection, must be noted on the weekly
report as a deficiency and resolved as soon as possible, immediately in most cases. A second report
must be submitted if the agency inspection occurs after the first weekly report was submitted and the
inspector identifies any deficiencies.
Stormwater Management Plan (SWMP)
Kum & Go Store #0951
SWMP Template REV April 2019 Page 5
The General Contractor must call the Owner’s Engineer to report the agency inspection immediately,
but no later than 1-hour after the inspector has left the jobsite. All stormwater or erosion and sediment
(E&S) agency visits to the jobsite, whether an official inspection occurred or not, must be reported to
the Owner’s Engineer. Any agency inspector, including OSHA and utility inspectors, that comment on
stormwater CCMs (inlet protection, track out, etc.) must be reported to the Owner’s Engineer.
A log of all inspections by Federal, State, or local stormwater or other environmental agencies shall
be kept in the General Contractor SWMP Ledger. The log form can be found in Appendix E and
must include the date and time of the visit and whether a report was issued or will be issued as a
result of the inspection.
o Inspector: Inspections must be conducted by a “Qualified Stormwater Manager”. “Qualified
Stormwater Manager” is defined in Appendix O. The inspector must be a person familiar with the
site, the nature of the major construction activities, and qualified to evaluate both overall system
performance and individual component performance. The inspector must either be someone
empowered to implement CMs in order to increase effectiveness to an acceptable level or someone
with the authority to cause such things to happen. Additionally, the inspector shall be properly
authorized in accordance with the applicable General Permit to conduct the certified site stormwater
inspections.
o Recordkeeping: It is imperative that documentation of the inspection and maintenance of all erosion
and sediment control measures be completed as soon as possible after the inspection and/or
maintenance is concluded but no more than 2 hours after conclusion of any inspection or
maintenance activity. The inspection reports shall include the date and time of inspection, the
inspector, a summary of the inspection, rain gauge readings, and identify any incidents of non-
compliance with the permit conditions. Where a report does not identify any incidents of non-
compliance, the report must contain a certification that the Project is in compliance with the SWMP
and the Construction General Permit or other applicable State Permit. The report must be signed in
accordance with CDPS General Permit Stormwater Discharges Associated with Construction Activity
Authorization to Discharge Under the Colorado Discharge Permit System Part I.A.3.f. These records
are used to prove that the required inspection and maintenance were performed and shall be printed
and placed in the SWMP Ledger. In addition to inspection and maintenance reports, records should
be kept of the Construction Activities that occur on the site. The Contractor shall retain copies of the
SWMP, all reports and data in paper and CD format for a minimum of three (3) years after the
Project is complete.
The forms found in this SWMP shall be used by the Qualified Stormwater Manager(s) to inventory
and report the condition of each measure to assist in maintaining the erosion and sediment control
measures in good working order.
o Construction Activity
A record of dates must be maintained when:
o major ground-disturbing activities including earthwork or grubbing occur;
o installation of structural controls;
o construction activities temporarily or permanently cease on a portion of the site;
o stabilization measures are initiated or completed;
o descriptions of the character and amount of any spills of Hazardous Substances or Oil
o reports filed with regulatory agencies if reportable quantities of Hazardous Substances or Oil
spilled
o an area is stabilized either temporarily or permanently; and
o CCMs are installed or permanently removed.
This log must be maintained in the SWMP until the NOT is filed.
Stormwater Management Plan (SWMP)
Kum & Go Store #0951
SWMP Template REV April 2019 Page 6
For convenience, a Record of Stabilization and Construction Activity Dates (Stabilization) log for
documenting such activities is included in Appendix I. At a minimum, the contractor shall be required
to document stabilization measures and implementation dates on his maps.
Controls must be in place down gradient of any ground-disturbing activities prior to the
commencement of grading construction activities and noted on the Site Maps and the Stabilization
log. Site Map and Stabilization log comments and entries must complement one another with greater
detail provided in the Stabilization log, as needed.
G. SPILLS OR RELEASES OF HAZARDOUS SUBSTANCES: Discharge of petroleum products or other
hazardous substances into stormwater or the stormwater (storm sewer) system is subject to reporting and
clean up requirements. Spills in excess of reportable quantities (as established under 40 CFR Part 110,
40 CFR Part 117 or 40 CFR Part 302) must be reported. Refer to the Construction General Permit for
additional information. A copy of the Spill Report Form is located in Appendix F and the Construction
General Permit is located in Appendix B.
H. TRAINING: Although not required by the State Permit, it is recommended that the Contractor provide
training sessions for all entities and subcontractors involved with installing, applying, performing,
maintaining, and inspection of the SWMP. Logs of each training session can be completed by the
Contractor on the “Training Log” located in Appendix K and placed in the SWMP Ledger. Training shall
educate the attendees on construction requirements and inspection, recordkeeping, and maintenance
procedures for, and location and type of erosion and sediment control measures.
I. SWMP MODIFICATIONS: The inspection report should also identify if any revisions to the SWMP are
warranted due to unexpected conditions. The SWMP is meant to be a dynamic working guide that is to be
kept current and amended by the Qualified Inspector (or other party if so specified below) whenever:
1. There is a change in design, construction, operation, or maintenance at the construction site that has
or could have a significant effect on the discharge of pollutants to the Waters of the United States that
has not been previously addressed in the SWMP. In addition to modifying the SWMP, the Site Map
may also require an amendment. Modifications to the SWMP and/or Site Map in relation to any
change in design, construction, operation, or maintenance at the construction site must be made
within 48 hours of such change.
2. Inspections or investigations by site staff, or by local, state or federal officials, determine that the
SWMP is ineffective in eliminating or significantly minimizing pollutants in stormwater discharges from
the construction site. Modifications resulting relation to SWMP ineffectiveness resulting from an
inspection must be initiated within 48 hours.
3. CMs are modified or additional CMs are designed to correct problems identified during an inspection.
Revisions to the SWMP related to additional or modified CMs must be completed within 48 hours
following the inspection.
4. There is a release involving a Hazardous Substance or Oil in an amount equal or in excess of a
reportable quantity established under either 40 CFR Part 110, 40 CFR Part 117 or 40 CFR Part 302.
Revisions to the SWMP must be completed within seven (7) calendar days of knowledge of the
release.
5. A change in design, construction, operation or maintenance materially affects the site’s spill potential
per 40 CFR Part 112. Modifications to the SWMP in relation to such change must be made within 48
hours of the change.
6. There is an off-site borrow or fill area that is used solely for the Project. The modification will be made
by the Contractor and will include, at a minimum, a revision to the SWMP and site maps and may
impact the Contractor’s duty to implement and conduct inspections. Any modification will also be
made within 48 hours. The Contractor’s failure to modify the SWMP to include off-site borrow or fill
Stormwater Management Plan (SWMP)
Kum & Go Store #0951
SWMP Template REV April 2019 Page 7
areas used solely for the Project or to monitor or report deficiencies to the Operator will result in the
Contractor being liable for fines and construction delays resulting from any federal, state, or local
agency enforcement action.
7. Modifications or changes in locations of materials management CMs shown on the Site Map.
Documentation of such modifications or changes must be documented on Appendix G and depicted
on the Site Map within 48 hours of the change.
8. Any such changes to the SWMP must be made in writing on the SWMP Amendment Log within 48
hours of the date such modification or amendment is made to the SWMP. Changes must also be
drawn on the Site Map within 48 hours of any modification or amendment is made to the SWMP.
9. The Operator or Inspector shall notify the governing agency, in writing, of any modifications made to
the SWMP.
J. TERMINATION OF PERMIT COVERAGE: A site can be considered finally stabilized when all soil
disturbing activities have been completed and:
1. All temporary CMs that were utilized for construction must be removed from the site.
2. A uniform perennial vegetative cover, as defined by Final Stabilization, for the unpaved areas and
areas not covered by permanent structures has been established or equivalent permanent
stabilization measures have been established
3. The facility no longer discharges stormwater associated with Construction Activities
4. A Notice of Termination (NOT) form is filed by the Operator(s) with the CDPHE. The NOT must be
submitted within 30 days of Final Stabilization. The Contractor shall complete the Contractor’s NOT
Certification and notify the Kum & Go Project Manager that sufficient cover has been achieved. A
copy of the NOT and Contractor’s NOT Certification is included in Appendix J.
NOTE: Stabilization requirements include all areas covered by applicable permits, including
outlots and utility easements, unless the new Owner and/or Operator have submitted a NOT(s)
to the applicable agency and a copy of the NOT(s) has been put in the SWMP Ledger.
5. The NOT must be signed by the same signatory who signed the NOI (or by a person with an
equivalent position to the NOI signatory) and subsequently submitted to the appropriate agency.
6. Where discharging to an MS4, the signatory must also submit a copy of the NOT to the MS4 except
where the Project is permitted solely by the MS4 in which case the Contractor will comply with
appropriate MS4 termination requirements.
7. The Kum & Go Construction Project Manager will provide a completed copy of the NOT to the
Contractor for inclusion in the SWMP, which will then be digitally scanned into the final SWMP
document as required. The requirements of the SWMP, including periodic inspections, must be
continued until the NOT is filed. Once the NOT has been approved, coverage under the Construction
General Permit is terminated and the Contractor’s responsibility to implement the SWMP is
completed.
8. If requested by the Kum & Go Construction Project Manager, the Pre-NOT Inspection and Pre-NOT
Inspection Checklist will be completed by the Operator’s Engineer as included in Appendix J.

Stormwater Management Plan (SWMP)
Kum & Go Store #0951
SWMP Template REV April 2019 Page 19
SECTION 5: EROSION AND SEDIMENT CONTROLS
Potential sources of sediment to stormwater runoff include:
Clearing, grading, and excavating activities, primarily un-stabilized areas, paving operations, demolition and
debris disposal, dewatering operations, drilling and blasting, material delivery, storage and use, and
landscaping operations.
See Site Maps and Construction Documents for CM installation locations and details.
5.1 Natural Buffers or Equivalent Sediment Controls
For construction projects where clearing and grading activities occur, a minimum of twenty-five (25) feet must be
provided of natural buffer zone, measured horizontally from the top of the bank to the disturbed area, from any
name or unnamed stream, creek, river, lake, or other water body. Additional buffer zones may be required
dependent on the adjacent water body as determined by the governing body.
Will any trees be preserved during construction?
Yes, this project will practice tree preservation as a non-structural CM. Refer to the landscape plan
contained in the most current set of construction documents for this development location of preserved
trees.
No, no trees will be preserved during this project.
5.2 Perimeter Controls
1. Silt Fence – Silt fence is a temporary sediment barrier consisting of a synthetic fabric stretched across
and attached to supporting posts and entrenched or sliced in place. Silt fence can be used in the following
applications:
Intercepting and detaining small amounts of sediment from disturbed areas during construction
operations in order to prevent sediment from leaving the construction site,
decreasing the velocity of sheet flows,
in high-risk areas, such as those adjacent to streams, wetlands, reservoirs, lawns, etc.,
in short lengths at the toe of fill where ground slopes toward the fill,
behind curb and gutter to prevent silting of the pavement.
Prior to the start of construction, silt fence placement should be designed by a qualified professional.
Plans and specifications should be referred to by field personnel throughout the construction process.
Use limitations include:
If the size of the drainage areas is more than 1/4-acre per 100 feet of silt fence length, a different
sediment and erosion control strategy should be investigated. The maximum gradient behind the
barrier should be no more than 3:1.
Under no circumstances should silt fence be constructed in live streams, in swales, or ditch lines
where flows are likely to exceed 1 cubic foot per second.
On steep slopes, care should be given to placing the alignment of fence perpendicular to the general
direction of the flow.
Sediment barriers, traps, and basins must be inspected and they must be cleaned out at such time as
their original capacity has been reduced by 50 percent. All material excavated from behind sediment
barriers, in traps, and/or basins shall be incorporated into on-site soils or spread out on an upland portion
of the site and stabilized. To minimize the potential for sediment releases from the project site, perimeter
control devices shall be inspected with consideration given to changing up-gradient conditions.
2. Vehicle Tracking Control – A vehicle tracking control is a stabilized stone pad with a filter fabric
underliner located at any point where vehicular traffic will be entering or leaving a construction site to or
Stormwater Management Plan (SWMP)
Kum & Go Store #0951
SWMP Template REV April 2019 Page 20
from a public right-of-way, street, alley, sidewalk or parking area. Its purpose is to reduce or eliminate the
tracking of sediment onto public rights-of-way or streets. It should be used wherever traffic will be leaving
a construction site and move directly onto a public road or other paved area.
Exits shall be maintained or supplemented with additional rock, as necessary, to prevent the release of
sediment from vehicles leaving the site. Any sediment deposited onto the surface of off-site streets,
paved areas, and sidewalks shall be swept, shoveled, or vacuumed, as necessary, throughout the day or
at the end of every day and disposed of in an appropriate manner. Sediment shall NOT be swept or
washed directly into storm sewer system(s).
3. Check Dams – Check dams are small temporary dams constructed across a swale or drainage ditch for
the purpose of reducing the velocity of concentrated stormwater flows, thereby reducing erosion of the
swale or ditch. Check dams also trap small amounts of sediment generated in the ditch itself; however,
these are not sediment trapping practices and should not be used as such. Some specific applications
include the following:
Temporary ditches or swales which, because of their short length of service, cannot receive a non-
erodible lining but still need some protection to reduce erosion.
Permanent ditches or swales which cannot receive a permanent non-erodible lining for an extended
period of time.
Temporary or permanent ditches or swales which need protection during the establishment of grass
linings.
Use limitations include:
Use limited to small open channels which drain 10 acres or less.
Should not be used in an active stream.
Should not to be used where high flows or high velocities are expected.
In locating the check dam, consideration should be given to the effects and the reach of the
impounded water and sediment.
Storm flows across a deteriorated check dam can result in the loss of the structure and the washout
of accumulated sediment.
4. Diversions – A diversion is a channel constructed across a slope with a supporting ridge on the lower
side for the purpose of reducing the slope length and intercepting and diverting stormwater runoff to
stabilized outlets at non-erosive velocities. Diversions are used where:
a. Runoff from higher areas may damage property, cause erosion, or interfere with the establishment of
vegetation on lower areas;
b. Surface and/or shallow subsurface flow is damaging upland slopes; or
c. Slope length needs reduction to minimize soil loss.
5. Sediment Control Log – Sediment Control Logs are elongated tubes of compacted straw and or other
fibers that are installed along contours or at the base of slopes to help reduce soil erosion and retain
sediment. They function by shortening slope lengths; reducing runoff water velocity thus trapping
dislodged soil particles. They can work as check dams to prevent sheet, rill, and gully erosion.
5.3 Dust Control
Construction traffic must enter and exit the site at the vehicle tracking control. The purpose is to trap dust and
mud that would otherwise be carried off-site by construction traffic. Large areas of soil that are denuded of
vegetation and have no protection from particles being picked up and carried by wind should be protected with a
temporary cover or kept under control with water or other soil adhering products to limit wind transported particles
exiting the site perimeter.
Water trucks or other dust control agents will be used, as needed, during construction to reduce dust generated
on the site. Dust control must be provided by the General Contractor to a degree that is in compliance with
applicable local and state dust control regulations.
Stormwater Management Plan (SWMP)
Kum & Go Store #0951
SWMP Template REV April 2019 Page 21
5.4 Slope Controls
1. Slope Tracking – Slope Tracking is the technique used for surface roughening or scarification by means
of mechanical equipment. Slope Tracking creates grooves that are parallel to the slope contours. The
primary functions for Slope Tracking are to reduce erosion potential by decreasing runoff velocities, trap
sediment, increase the chances for water infiltration, and aid in the establishment of vegetative cover.
2. Rolled Erosion Control Products – Rolled erosion control products are protective covering netting,
blankets, or turf reinforcement mats (TRMs) installed on a prepared planting area of a steep slope,
channel, or shoreline. They aid in controlling erosion on critical areas by absorbing the energy from
raindrop impacts and providing a microclimate which protects young vegetation and promotes its
establishment. TRMs are also used to raise the maximum permissible velocity and shear stress of turf
grass stands in channelized areas by enabling the turf to resist the forces of erosion during storm events.
Rolled erosion control products (nets, blankets, turf reinforcement mats) and marginally vegetated areas
(areas not meeting required vegetative densities for final stabilization) must be inspected weekly. Rilling,
rutting, and other signs of erosion indicate the erosion control device is not functioning properly and
additional erosion control devices are warranted.
5.5 Storm Drain Inlets
Storm Sewer Inlet Protection – Storm sewer inlet protection is a sediment filter or an excavated impounding
area around a storm drain drop inlet or curb inlet. Its purpose is to prevent sediment from entering storm drainage
systems prior to permanent stabilization of the disturbed area. This practice shall be used where the drainage
area to an inlet is disturbed, it is not possible to temporarily divert the storm drain outfall into a trapping device,
and watertight blocking of the inlets is not advisable. It is not to be used in place of sediment trapping devices.
Note to General Contractor: All inlet protection devices create ponding of stormwater that can result in flooding
or by-pass conditions. Clean or remove and replace the protection measures as sediment accumulates, the filter
becomes clogged, and/or performance is compromised. Where evidence of sedimentation exists adjacent to the
inlet protection device, remove the deposited sedimentation by the end of the same work day that it is found.
5.6 Top Soil
A minimum of 4” of topsoil is required in all areas not covered by asphalt, concrete, gravel, or other materials.
Compliance with this measure is required at the time of Final Stabilization. Topsoil preservation can be achieved
with the assistance of the following measures.
1. Temporary Seeding – Temporary seeding is the establishment of a temporary vegetative cover on
disturbed areas by seeding with appropriate rapidly growing annual plants. Its purpose is to reduce
erosion and sedimentation by stabilizing disturbed areas that will be inactive for a period of fourteen
calendar days or more, reduce damage from sediment and runoff to downstream or off-site areas, and to
provide protection to bare soils exposed during construction until permanent vegetation or other erosion
control measures can be established. It should be used on exposed soil surfaces. Such areas include
denuded areas, soil stockpiles, dikes, dams, sides of sediment basins, temporary road banks, etc.,
permanent vegetative cover shall be applied to areas that will be left dormant for a period of more than 1
year.
Note to General Contractor: Temporary stabilization is not achieved simply through seeding. In order for
an area or stockpile to be sufficiently stabilized via temporary vegetation, seed must germinate, grow, and
provide adequate vegetative density.
2. Permanent Seeding – Permanent vegetation is the establishment of perennial vegetative cover on
disturbed areas by planting seed. Its purpose is to reduce erosion and sediment yield from disturbed
areas, to permanently stabilize disturbed areas in a manner that is economical, adaptable to site
Stormwater Management Plan (SWMP)
Kum & Go Store #0951
SWMP Template REV April 2019 Page 22
conditions, and allows selection of the most appropriate plant materials to improve wildlife habitat and to
enhance natural beauty. It may be used on disturbed areas where permanent, long-lived vegetative cover
is needed to stabilize the soil and rough-graded areas that will not be brought to final grade for a year or
more.
3. Hydroseeding/Hydromulching – Hydroseeding/Hydromulching is a grass planting process. The process
begins by mixing mulch, seed, tackifier, fertilizer, and water into the tank of a hydromulching machine.
The material is often called slurry. Once applied to the soil, the material enhances initial growth.
Consideration must be given to anticipated climate and seasonal conditions when specifying and planting
seed. Seed shall be free of weedy species and appropriate for site soils and regional climate. Seed and
mulch per the construction drawings and the planting specification immediately after topsoil is applied and
final grade is reached. Grassed areas shall be inspected to confirm that a healthy stand of grass is
maintained. Vegetated areas must be watered, fertilized, and reseeded, as needed, to achieve this
requirement. The vegetative density must be maintained through project completion to be considered
stabilized. Areas protected by erosion control blankets are not permanently stabilized until the applicable
General Permit requirement for final vegetative density is achieved.
4. Mulching – Mulching is the application of organic material over soil that is bare or immediately over soil
that has been seeded. Mulch prevents erosion by preventing the detachment of soil particles, slows runoff
velocity, and retains moisture to improve germination and establishment of vegetative cover.
Rip-rap, mulch, gravel, decomposed granite, or other equivalent permanent stabilization measures may
be employed in lieu of vegetation based on site-specific conditions and governing authority approval.
5.7 Dewatering Practices
Construction dewatering is now covered under the CDPHE Low Risk Discharge Guidance. Obtain a dewatering
permit according to the regulations if discharges from dewatering activities are not allowed under the General
Permit. Discharges from dewatering operations must be directed through an appropriate pollution
prevention/treatment measure, such as a pump discharge filter bag, sediment trap, or sediment basin prior to
being discharged from the site. Under no circumstances are discharges from dewatering operations to be
discharged directly into streams, rivers, lakes, or other areas off-site. Likewise, discharges into storm sewer
systems that do not drain to a suitable on-site treatment facility, such as a basin, are also prohibited. Discharges
from dewatering operations must also be conducted in a manner sufficient to prevent erosion from the discharge
runoff.
5.8 Post Construction CMs – Operations and Maintenance
The Contractor is responsible for proper installation, maintenance and functioning of all best management
practices shown on the drawings until final stabilization is achieved. A copy of the Post Construction Stormwater
CM Operations and Maintenance Plan is included in Appendix P of this document.
An Operations and Maintenance Plan for the underground detention will be developed prior to obtaining a
certificate of occupancy for the convenience store. The manual will be filed with the City of Fort Collins
Engineering Department.
5.9 Other Stormwater Controls
SWMP Administrator shall continually update and monitor the stormwater controls list and ensure that
each stormwater control BMP description and detail is added to the SWMP.
General house keeping
Periodic training – in addition to structural BMPs the contractor is to practice general housekeeping and
conduct periodic training his/her employees.

6.2 Spill Prevention and Response
Any hazardous or potentially hazardous material that is brought onto the construction site will be handled properly
in order to reduce the potential for stormwater pollution. All materials used on this construction site will be properly
stored, handled, dispensed, and disposed of following all applicable label directions. Flammable and combustible
liquids will be stored and handled according to 29 CFR 1926.152. Only approved containers and portable tanks
shall be used for storage and handling of flammable and combustible liquids.
Safety Data Sheets (SDS) information will be kept on site for any and all applicable materials.
In the event of an accidental spill, immediate action will be undertaken by the General Contractor to contain and
remove the spilled material. All hazardous materials will be disposed of by the General Contractor in the manner
specified by federal, state, and local regulations and by the manufacturer of such products. As soon as possible,
the spill will be reported to the appropriate agencies. As required under the provisions of the Clean Water Act, any
spill or discharge entering waters of the United States will be properly reported. The General Contractor should
prepare a written record of any spill of petroleum products or hazardous materials in excess of 1 gallon or
reportable quantities, whichever is less. The General Contractor will provide notice to the Owner immediately
upon identification of a reportable spill. A Spill Report Form is located in Appendix F.
Any spills of petroleum products or hazardous materials in excess of Reportable Quantities as defined by EPA,
the state, or local agency regulations, shall be immediately reported to the EPA National Response Center (1-
800-424-8802) and CDPHE 24-hour Environmental Emergency Reporting and Incident Reporting (1-877-518-
5608).
In order to minimize the potential for a spill of petroleum products or hazardous materials to come in contact with
stormwater, the following steps will be implemented:
a) All materials with hazardous properties (such as pesticides, petroleum products, fertilizers,
detergents, construction chemicals, acids, paints, paint solvents, additives for soil stabilization,
concrete, curing compounds and additives, etc.) should be stored in a secure location, under cover,
when not in use.
b) The minimum practical quantity of all such materials should be kept on the job site and scheduled for
delivery as close to time of use as practical.
c) A spill control and containment kit (containing for example, absorbent material such as kitty litter or
sawdust, acid neutralizing agent, brooms, dust pans, mops, rags, gloves, goggles, plastic and metal
trash containers, etc.) will be provided on the construction site and location(s) shown on Site Maps.
d) All of the product in a container should be used before the container is disposed of. The containers
will be disposed of in a manner in compliance with state and federal regulations and will not be
allowed to mix with stormwater discharges.
e) All products should be stored in and used from the original container with the original product label.
Stormwater Management Plan (SWMP)
Kum & Go Store #0951
SWMP Template REV April 2019 Page 26
f) All products will be used in strict compliance with instructions on the product label.
g) The disposal of excess or used products will be in strict compliance with instructions on the products
label.
6.3 Fueling and Maintenance of Equipment or Vehicles
Temporary on-site fuel tanks for construction vehicles shall meet all state and federal regulations. Tanks shall
have approved spill containment with the capacity required by the applicable regulations. From NFPA 30: All
tanks shall be provided with secondary containment (i.e. containment external to and separate from primary
containment). Secondary containment shall be constructed of materials of sufficient thickness, density, and
composition such that the materials used will not be structurally weakened as a result of contact with the fuel
stored and capable of containing discharged fuel for a period of time equal to or longer than the maximum
anticipated time sufficient to allow recovery of discharged fuel. It shall be capable of containing 110% of the
volume of the primary tank, if a single tank is used, or in the case of multiple tanks, 150% of the largest tank or
110% of the aggregate, whichever is larger.
The tanks shall be in sound condition, free of rust or other damage which might compromise containment. Fuel
storage areas will meet all EPA, OSHA, and other regulatory requirements for signage, fire extinguisher, etc.
Hoses, valves, fittings, caps, filler nozzles, and associated hardware shall be maintained in proper working
condition at all times. The location of fuel tanks shall be shown on the Site Maps and shall be located to minimize
exposure to weather and surface water drainage features.
A Spill Prevention, Control, and Countermeasure (SPCC) Plan must be developed if aboveground oil storage
capacity at the construction site exceeds 1,320-gallons or as specified by state. Containers with a storage
capacity of less than 55-gallons are not included when calculating site storage capacity. The General Contractor
shall work with the Owner’s Engineer to develop and implement a SPCC Plan in accordance with the Oil Pollution
Prevention regulation at Title 40 of the Code of Federal Regulations, Part 112, 6.4
6.4 Mason’s Area
The General Contractor shall identify the mason’s area on the site and indicate the location on the Site Map. To
the extent practical, all masonry tools, material, including sand and sacked cement or mortar materials, and
equipment shall be located within the area identified. Runoff control, such as berms or diversion ditches, silt
fence, straw wattles, or other means of containment shall be provided to prevent the migration of stormwater
pollutants in runoff from the mason’s area. Receptacles for debris and trash disposal shall also be provided.
6.5 Concrete Waste from Concrete Ready-Mix Trucks
Discharge of excess or waste concrete and/or wash water from concrete trucks will be allowed on the
construction site, but only in specifically designated lined and diked areas prepared to prevent contact between
the concrete and/or wash water and stormwater that will be discharged from the site. Alternatively, waste concrete
can be placed into forms to make rip-rap or other useful concrete products. The cured residue from the concrete
washout diked areas shall be disposed in accordance with applicable state and federal regulations. The project
construction manager is responsible for assuring that these procedures are followed. The location of concrete
washout areas shall be shown on the Site Maps. All applicable environmental regulations for concrete wash out
pits must be adhered to.
6.6 Construction and Domestic Waste
No solid materials, including building materials, are allowed to be discharged from the site with stormwater. All
solid waste, including disposable materials incidental to the major construction activities, must be collected and
placed in containers. The containers will be emptied, as necessary, by a contract trash disposal service and
Stormwater Management Plan (SWMP)
Kum & Go Store #0951
SWMP Template REV April 2019 Page 27
hauled away from the site. Covers for the containers should be provided, as necessary, to meet state and local
requirements. The location of solid waste receptacles shall be shown on the Site Maps.
Substances that have the potential for polluting surface and/or groundwater must be controlled by all means
necessary in order to ensure that they do not discharge from the site. As an example, special care must be
exercised during equipment fueling and servicing operations. If a spill occurs, it must be contained and disposed
of such that it will not flow from the site or enter groundwater, even if this requires removal, treatment, and
disposal of soil. In this regard, potentially polluting substances should be handled in a manner consistent with the
impact they represent.
6.7 Sanitary Waste
All personnel involved with construction activities must comply with state and local sanitary or septic system
regulations. Temporary sanitary facilities will be provided at the site throughout the construction phase. They must
be utilized by all construction personnel and will be serviced by a commercial operator. The location of sanitary
facilities shall be shown on the Site Maps. Portable toilets must be securely anchored and are not allowed within
30’ of stormwater inlets or permitted limit of disturbance or within 50’ of a water of the State.
6.8 Material Storage Area
Inspections shall evaluate disturbed areas and areas used for storing materials that are exposed to rainfall for
evidence of, or the potential for, pollutants entering the drainage system or discharging from the site. If necessary,
the materials must be covered, or original covers must be repaired or supplemented. Also, protective berms must
be constructed, if needed, in order to contain runoff from material storage areas. All state and local regulations,
pertaining to material storage areas, will be adhered to.
6.9 Non-Stormwater Discharges
Non-stormwater components of site discharges must be clean water. Water used for construction, which
discharges from the site, must originate from a public water supply or private well approved by the State Health
Department. Water used for construction, which does not originate from an approved public supply, must not
discharge from the site. It can be retained in the ponds until it infiltrates and evaporates. Other non-stormwater
discharges would include ground water. Only uncontaminated ground water can be discharged from the site, as
allowed by and in accordance with applicable local ground water dewatering permits/regulations. When non-
stormwater is discharged from the site, it must be done in a manner such that it does not cause erosion of the soil
during discharge.
Process water, such as power washing and concrete cutting, must be collected for treatment and disposal. It is
not to be flushed into the site storm drain system.

Note: All personnel conducting inspections must be considered a “Qualified Stormwater Manager” per
Section 1.3 (F) of this SWMP.
Inspection Schedule
Specific Inspection Frequency
General contractor to determine BMP inspection frequency.
[Part I.D.2 of the CDPS Stormwater Construction Permit requires that a minimum inspection schedule of:
At least one inspection every 7 calendar days. Or
At least one inspection every 14 calendar days, if post-storm event inspections are conducted within 24
hours after the end of any precipitation or snowmelt event that causes surface erosion. Post-storm
inspections may be used to fulfill the 14-dayroutine inspection requirement.
When site conditions make the schedule required in this section impractical, the permittee may petition
the Division to grant an alternate inspection schedule. The alternative inspection schedule may not be
implemented prior to written approval by the division and incorporation into the SWMP.
The permittee must maintain a record of the inspection results and SWMP for a period no less than 3 years
following inactivation or expiration of permit coverage. These records must be made available upon request to
the EPA and Water Quality Control Division (WQCD) of the CDPHE.]
Reductions in Inspection Frequency (if applicable)
1) Post-Storm Event Inspections at Temporarily Idle Sites – If no construction activities will occur following a
storm event, post-storm event inspections shall be conducted prior to re-commencing construction activities,
but no later than 72 hours following the storm event. The occurrence of any such delayed inspection must be
documented in the inspection record. Routine inspections still must be conducted at least every 14 calendar
days.
2) Inspections at Completed Sites/Areas – For sites or portions of sites that meet the following criteria, but final
stabilization has not been achieved due to a vegetative cover that has not become established, the permittee
shall make a thorough inspection of their stormwater management system at least once every 30 days., Post-
storm event inspections are not required. This reduced inspection schedule is only allowed if:
all construction activities that will result in surface ground disturbance are completed;
Stormwater Management Plan (SWMP)
Kum & Go Store #0951
SWMP Template REV April 2019 Page 29
all activities required for final stabilization, in accordance with the SWMP, have been completed, with the
exception of the application of seed that has not occurred due to seasonal conditions or the necessity for
additional seed application to augment previous efforts; and
the SWMP has been amended to indicate those areas that will be inspected in accordance with the
reduced schedule allowed for in this paragraph.
3) Winter Conditions Inspections Exclusion – Inspections are not required at sites where construction activities
are temporarily halted, snow cover exists over the entire site for an extended period, and melting conditions
posing a risk of surface erosion do not exist. This exception is applicable only during the period where melting
conditions do not exist, and applies to the routine 7-day, 14-day and monthly inspections, as well as the post-
storm-event inspections. The following information must be documented in the inspection record for use of this
exclusion: dates when snow cover existed, date when construction activities ceased, and date melting
conditions began. Inspections, as described above, are required at all other times.
When site conditions make the schedule required in this section impractical, the permittee may petition the
Division to grant an alternate inspection schedule.

stormwater associated with construction activity and specified non-stormwater associated
with construction activity. The following types of stormwater and non-stormwater
discharges are authorized under this permit:
a. Allowable Stormwater Discharges
i. Stormwater discharges associated with construction activity.
ii. Stormwater discharges associated with producing earthen materials, such as soils,
sand, and gravel dedicated to providing material to a single contiguous site, or
within ¼ mile of a construction site (i.e. borrow or fill areas)
iii. Stormwater discharges associated with dedicated asphalt, concrete batch plants
and masonry mixing stations (Coverage under this permit is not required if
alternative coverage has been obtained.)
b. Allowable Non-Stormwater Discharges
The following non-stormwater discharges are allowable under this permit if the
discharges are identified in the stormwater management plan in accordance with Part
I.C. and if they have appropriate control measures in accordance with Part 1.8.1.
i. Discharges from uncontaminated springs that do not originate from an area of land
disturbance.
ii. Discharges to the ground of concrete washout water associated with the washing of
concrete tools and concrete mixer chutes. Discharges of concrete washout water
must not leave the site as surface runoff or reach receiving waters as defined by
this permit.
iii. Discharges of landscape irrigation return flow.
c. Emergency Fire Fighting
Discharges resulting from emergency firefighting activities are authorized by this
permit.
2. Limitations on Coverage
Discharges not authorized by this permit include, but are not limited to, the discharges
and activities listed below. Permittees may seek individual or alternate general permit
coverage for the discharges, as appropriate and available.
a. Discharges of Non-Stormwater
Page 1 of 33
PART I
Permit No.: COR400000

the division may:
i.
Issue a certification of coverage;
ii. request additional information necessary to evaluate the discharge;
iii. delay the authorization to discharge pending further review;
iv. notify the applicant that additional terms and conditions are necessary; or
v.
deny the authorization to discharge under this general permit.
d. Alternative Permit Coverage
i. Division Required Alternate Permit Coverage:
The Division may require an applicant or permittee to apply for an individual
permit or an alternative general permit if it determines the discharge does not fall
under the scope of this general permit. In this case, the Division will notify the
applicant or permittee that an individual permit application is required.
ii. Permittee Request for alternate permit coverage:
A permittee authorized to discharge stormwater under this permit may request to
be excluded from coverage under this general permit by applying for an individual
permit. In this case, the permittee must submit an individual application, with
reasons supporting the request, to the Division at least 180 days prior to any
discharge. When an individual permit is issued, the permittee's authorization to
discharge under this permit is terminated on the effective date of the individual
permit.
e. Submittal Signature Requirements
Page 3 of 33
PARTI
Permit No.: COR400000
Documents required for submittal to the division in accordance with this permit,
including applications for permit coverage and other documents as requested by the
division, must include signatures by both the owner and the operator, except for
instances where the duties of the owner and operator are managed by the owner.
Signatures on all documents submitted to the division as required by this permit must
meet the Standard Signatory Requirements in Part 11.K. of this permit in accordance
with 40 C.F.R. 122.41 (k).
i. Signature Certification

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."
f. Compliance Document Signature Requirements
Documents which are required for compliance with the permit, but for which
submittal to the division is not required unless specifically requested by the division,
must be signed by the individual(s) designated as the Qualified Stormwater Manager,
as defined in Part I.E.
i. Any person(s) signing inspection documents required for compliance with the
permit must make the following statement:
"I verify that, to the best of my knowledge and belief, all corrective action and
maintenance items identified during the inspection are complete, and the site is
currently in compliance with the permit."
g. Field Wide Permit Coverage for Oil and Gas Construction
At the discretion of the division, a single permit certification may be issued to a single
oil and gas permittee to cover construction activity related discharges from an oil and
gas field at multiple locations that are not necessarily contiguous.
h. Permit Coverage without Application
Qualifying Local Program: When a small construction site is within the jurisdiction of a
qualifying local program, the owner and operator of the construction activity are
authorized to discharge stormwater associated with small construction activity under
this general permit without the submittal of an application to the division. Sites
covered by a qualifying local program are exempt from the following sections of this
general permit:
Page 4 of 33
PARTI
Permit No.: COR400000
Part I.A.3.a.; Part I.A.3.b.; Part I.A.3.c.; Part I.A.3.d.; Part I.A.3.g.; Part I.A.3.i.; Part
I.A.3.j.; Part I.A.3.k.
Sites covered by a qualifying local program are subject to the following requirements:
i. Local Agency Authority: This permit does not pre-empt or supersede the authority
of local agencies to prohibit, restrict, or control discharges of stormwater to storm
drain systems or other water courses within their jurisdiction.
ii. Permit Coverage Termination: When a site under a Qualifying Local Program is
finally stabilized, coverage under this permit is automatically terminated.
iii. Compliance with Qualifying Local Program: Qualifying Local Program requirements
that are equivalent to the requirements of this permit are incorporated by
reference. Permittees authorized to discharge under this permit, must comply
with the equivalent requirements of the Qualifying Local Program that has
jurisdiction over the site as a condition of this permit.
iv. Compliance with Remaining Permit Conditions. Requirements of this permit that
are in addition to or more stringent than the requirements of the Qualifying Local
Program apply in addition to the requirements of the Qualifying Local Program.
v. Written Authorization of Coverage: The division or local municipality may require
any permittee within the jurisdiction of a Qualifying Local Program covered under
this permit to apply for, and obtain written authorization of coverage under this
permit. The permittee must be notified in writing that an application for written
authorization of coverage is required.
i, Permittee Initiated Permit Actions
Permittee initiated permit actions, including but not limited to modifications, contact
changes, transfers, reassignments, and terminations, shall be conducted following
division guidance and using appropriate division-provided forms.
j. Sale of Residence to Homeowner
Residential construction sites only: The permittee may remove residential lots from
permit coverage once the lot meets the following criteria:
i. the residential lot has been sold to the homeowner(s) for private residential use;
ii. a certificate of occupancy, or equivalent, is maintained on-site and is available
during division inspections;
iii. the lot is less than one acre of disturbance;
iv. all construction activity conducted on the lot by the permittee is complete;
v. the permittee is not responsible for final stabilization of the lot; and
vi. the SWMP was modified to indicate the lot is no longer part of the construction
activity.
If the residential lot meets the criteria listed above then activities occurring on the lot
are no longer considered to be construction activities with a duty to apply and
maintain permit coverage. Therefore, the permittee is not required to meet the final
stabilization requirements and may terminate permit coverage for the lot.
Page 5 of 33
k. Permit Expiration and Continuation of Permit Coverage
PART I
Permit No.: COR400000
Authorization to discharge under this general permit shall expire at midnight on March
31, 2024. While Regulation 61.4 requires a permittee to submit an application for
continuing permit coverage 180 days before the permit expires, the division is
requiring that permittees desiring continued coverage under this general permit must
reapply at least 90 days in advance of this permit expiration. The Division will
determine if the permittee may continue to discharge stormwater under the terms of
the general permit. An individual permit may be required for any facility not
reauthorized to discharge under the reissued general permit.
If this permit is not reissued or replaced prior to the expiration date, it will be
administratively continued and remain in force and effect. For permittees that have
applied for continued permit coverage, discharges authorized under this permit prior
to the expiration date will automatically remain covered by this permit until the
earliest of:
i. An authorization to discharge under a reissued permit, or a replacement of this
permit, following the timely and appropriate submittal of a complete application
requesting authorization to discharge under the new permit and compliance with
the requirements of the new permit; or
ii. The issuance and effect of a termination issued by the Division; or
iii. The issuance or denial of an individual permit for the facility's discharges; or
iv. A formal permit decision by the Division not to reissue this general permit, at
which time the Division will identify a reasonable time period for covered
dischargers to seek coverage under an alternative general permit or an individual
permit. Coverage under this permit will cease when coverage under another
permit is granted/authorized; or
v. The Division has informed the permittee that discharges previously authorized
under this permit are no longer covered under this permit.
6. EFFLUENT LIMITATIONS
1. Requirements for Control Measures Used to Meet Effluent Limitations
The permittee must implement control measures to minimize the discharge of pollutants
from all potential pollutant sources at the site. Control measures must be installed prior
to commencement of activities that may contribute pollutants to stormwater discharges.
Control measures must be selected, designed, installed and maintained in accordance
with good engineering, hydrologic and pollution control practices. Control measures
implemented at the site must be designed to prevent pollution or degradation of state
waters.
a. Stormwater Pollution Prevention
The permittee must implement structural and/or nonstructural control measures that
effectively minimize erosion, sediment transport, and the release of other pollutants
related to construction activity.
i.
Control Measures for Erosion and Sediment Control
Page 6 of 33
PART I
Permit No.: COR400000
Control measures for erosion and sediment control may include, but are not
limited to, wattles/sediment control logs, silt fences, earthen dikes, drainage
swales, sediment traps, subsurface drains, pipe slope drains, inlet protection,
outlet protection, gabions, sediment basins, temporary vegetation, permanent
vegetation, mulching, geotextiles, sod stabilization, slope roughening, maintaining
existing vegetation, protection of trees, and preservation of mature vegetation.
Specific non-structural control measures must meet the requirements listed below.
Specific control measures must meet the requirements listed below.
(a) Vehicle tracking controls shall either be implemented to minimize vehicle
tracking of sediment from disturbed areas, or the areas where vehicle tracking
occurs shall meet subsection Part I.B.1.a.i(b);
(b) Stormwater runoff from all disturbed areas and soil storage areas for which
permanent or temporary stabilization is not implemented, must flow to at least
one control measure to minimize sediment in the discharge. This may be
accomplished through filtering, settling, or straining. The control measure
must be selected, designed, installed and adequately sized in accordance with
good engineering, hydrologic and pollution control practices. The control
measure(s) must contain or filter flows in order to prevent the bypass of flows
without treatment and must be appropriate for stormwater runoff from
disturbed areas and for the expected flow rate, duration, and flow conditions
(i.e., sheet or concentrated flow);
(c) Outlets that withdraw water from or near the surface shall be installed when
discharging from basins and impoundments, unless infeasible.
(d) Maintain pre-existing vegetation or equivalent control measures for areas
within 50 horizontal feet of receiving waters as defined by this permit, unless
infeasible.
(e) Soil compaction must be minimized for areas where infiltration control
measures will occur or where final stabilization will be achieved through
vegetative cover.
(f) Unless infeasible, topsoil shall be preserved for those areas of a site that will
utilize vegetative final stabilization.
(g) Minimize the amount of soil exposed during construction activity, including the
disturbance of steep slopes.
ii. Practices for Other Common Pollutants
(a) Bulk storage, 55 gallons or greater, for petroleum products and other liquid
chemicals must have secondary containment, or equivalent protection, in order
to contain spills and to prevent spilled material from entering state waters.
(b) Control measures designed for concrete washout waste must be implemented.
This includes washout waste discharged to the ground as authorized under this
permit and washout waste from concrete trucks and masonry operations
contained on site. The permittee must ensure the washing activities do not
contribute pollutants to stormwater runoff, or receiving waters in accordance
Part I .A. 1. b. ii. Discharges that may reach groundwater must flow through soil
Page 7 of 33
PART I
Permit No.: COR400000
that has buffering capacity prior to reaching groundwater, as necessary to
meet the effluent limits in this permit, including Part I.B.3.a. The concrete
washout location shall be not be located in an area where shallow
groundwater may be present and would result in buffering capacity not being
adequate, such as near natural drainages, springs, or wetlands. This permit
authorizes discharges to the ground of concrete washout waste.
iii. Stabilization Requirements
The following requirements must be implemented for each site.
(a) Temporary stabilization must be implemented for earth disturbing activities
on any portion of the site where ground disturbing construction activity has
permanently ceased, or temporarily ceased for more than 14 calendar days.
Temporary stabilization methods may include, but are not limited to, tarps,
soil tackifier, and hydroseed. The permittee may exceed the 14-day schedule
when either the function of the specific area of the site requires it to remain
disturbed, or, physical characteristics of the terrain and climate prevent
stabilization. The SWMP must document the constraints necessitating the
alternative schedule, provide the alternate stabilization schedule, and identify
all locations where the alternative schedule is applicable on the site map.
(b) Final stabilization must be implemented for all construction sites. Final
stabilization is reached when all ground surface disturbing activities at the
construction site are complete; and, for all areas of ground surface disturbing
activities, either a uniform vegetative cover with an individual plant density of
at least 70 percent of pre-disturbance levels is established, or equivalent
permanent alternative stabilization methods are implemented. The division
may approve alternative final stabilization criteria for specific operations.
(c) Final stabilization must be designed and installed as a permanent feature. Final
stabilization measures for obtaining a vegetative cover or alternative
stabilization methods include, but are not limited to, the following as
appropriate:
(1) Seed mix selection and application methods;
(2) Soil preparation and amendments;
(3) Soil stabilization methods (e.g., crimped straw, hydro mulch or rolled
erosion control products);
(4) Appropriate sediment control measures as needed until final stabilization is
achieved;
(5) Permanent pavement, hardscape, xeriscape, stabilized driving surfaces;
(6) Other alternative stabilization practices as applicable;
Page 8 of 33
PART I
Permit No.: COR400000
(d) The permittee(s) must ensure all temporary control measures are removed
from the construction site once final stabilization is achieved, except when the
control measure specifications allow the control measure to be left in place
(i.e., bio-degradable control measures).
b. Maintenance
The permittee must ensure that all control measures remain in effective operating
condition and are protected from activities that would reduce their effectiveness.
Control measures must be maintained in accordance with good engineering, hydrologic
and pollution control practices. Observations leading to the required maintenance of
control measures can be made during a site inspection, or during general observations
of site conditions. The necessary repairs or modifications to a control measure
requiring routine maintenance, as defined in Part I.E., must be conducted to maintain
an effective operating condition. This section is not subject to the requirements in
Part I.B.1.c. below.
c. Corrective Actions
The permittee must assess the adequacy of control measures at the site, and the need
for changes to those control measures, to ensure continued effective performance.
When an inadequate control measure, as defined in Part I.E., is identified (i.e., new or
replacement control measures become necessary), the following corrective action
requirements apply. The permittee is in noncompliance with the permit until the
inadequate control measure is replaced or corrected and returned to effective
operating condition in compliance with Part I.B.1. and the general requirements in
Part I.B.3. If the inadequate control measure results in noncompliance that meets the
conditions of Part 11.L., the permittee must also meet the requirements of that
section.
i. The permittee must take all necessary steps to minimize or prevent the discharge
of pollutants, until a control measure is implemented and made operational and/or
an inadequate control measure is replaced or corrected and returned to effective
operating condition. If it is infeasible to install or repair of control measure
immediately after discovering the deficiency, the following must be documented
and kept on record in accordance with the recordkeeping requirements in Part II.
(a) Describe why it is infeasible to initiate the installation or repair immediately;
and
(b) Provide a schedule for installing or repairing the control measure and returning
it to an effective operating condition as soon as possible.
ii. If applicable, the permittee must remove and properly dispose of any unauthorized
release or discharge (e.g., discharge of non-stormwater, spill, or leak not
authorized by this permit.) The permittee must also clean up any contaminated
surfaces to minimize discharges of the material in subsequent storm events.
2. Discharges to an Impaired Waterbody
a. Total Maximum Daily Load (TMDL)
If the permittee's discharge flows to or could reasonably be expected to flow to any
water body for which a TMDL has been approved, and stormwater discharges
Page 9 of 33
PART I
Permit No.: COR400000
associated with construction activity were assigned a pollutant-specific Wasteload
Allocation (WLA) under the TMDL, the division may:
i. ensure the WLA is implemented properly through alternative local requirements,
such as by a municipal stormwater permit; or
ii. notify the permittee of the WLA and amend the permittee's certification to add
specific effluent limits and other requirements, as appropriate. The permittee may
be required to do the following:
(a) under the permittee's SWMP, implement specific control measures based on
requirements of the WLA, and evaluate whether the requirements are met
through implementation of existing stormwater control measures or if
additional control measures are necessary. Document the calculations or other
evidence demonstrating that the requirements are expected to be met; and
(b) if the evaluation shows that additional or modified control measures are
necessary, describe the type and schedule for the control measure additions or
modifications.
iii. Discharge monitoring may also be required. The permittee may maintain coverage
under the general permit provided they comply with the applicable requirements
outlined above. The division reserves the right to require individual or alternate
general permit coverage.
3. General Requirements
a.
Discharges authorized by this permit shall not cause, have the reasonable potential to
cause, or measurably contribute to an exceedance of any applicable water quality
standard, including narrative standards for water quality.
b. The division may require sampling and testing, on a case-by-case basis, in the event
that there is reason to suspect that the SWMP is not adequately minimizing pollutants
in stormwater or in order to measure the effectiveness of the control measures in
removing pollutants in the effluent. Such monitoring may include Whole Effluent
Toxicity testing.
c. The permittee must comply with the lawful requirements of federal agencies,

SWMP Template REV April 2019
Appendix O – Definitions
Check Dam: A small dam generally placed in steep ditches for the purpose of reducing Velocity in the Ditch.
Clean Water Act (CWA): The Federal Water Pollution Prevention Control Act enacted in 1972 by Public Law 92-
500 and amended by the Water Quality Act of 1987. The Clean Water Act prohibits the discharge of pollutants to
Waters of the United States unless said discharge is in accordance with an NPDES permit. The 1987
amendments include guidelines for regulating municipal, industrial, and construction stormwater discharges under
the NPDES program.
Construction Activity:
Ground surface disturbing and associated activities (land disturbance), 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 the original line and grade, hydraulic capacity, or original purpose of the facility. Activities to conduct
repairs that are not part of routine maintenance or for replacement are construction activities and are not routine
maintenance. Repaving activities where underlying and/or surrounding soil is exposed as part of the repaving
operation are considered construction activities. Construction activity is from initial ground breaking to final
stabilization regardless of ownership of the construction activities.
Construction General Permit: A permit issued by EPA or an authorized state under the NPDES stormwater
regulations to cover the discharge from the construction site of stormwater associated with Construction Activity.
In order to be covered by a General Permit, the Operator must file a Notice of Intent (NOI), if required. For
coverage under a Construction General Permit, where either the EPA or a state is the NPDES authority, the
Project is validly covered by the Construction General Permit 14 days after EPA or state agency receipt of a
completed NOI, receipt of authorization letter, or EPA or the state agency does not request the Operator to apply
for an individual permit. Some states may require that the applicant first receive a plan approval or certificate of
coverage which confirms coverage for the Project under the Construction General Permit. In some states general
permits are issued as regulations and are applicable to projects in accordance with the terms of the regulation.
Contractor: Shall be that person or entity identified as such in the construction contract with the Operator. The
term “Contractor” shall also include the Contractor’s authorized representative, as well as any and all
subcontractors retained by the Contractor.
Contractor’s Project Manager: The Contractor’s employee or authorized representative identified by the
Contractor as the project manager for the Project. In some instances, this individual may also serve as the
Contractor’s Superintendent.
Contractor’s Superintendent: The Contractor’s employee who has oversight and management of the
construction process at the Project.
Control Measure: Any best management practice or other method used to prevent or reduce the
discharge of pollutants to state waters. Control measures include, but are not limited to, best
management practices. Control measures can include other methods such as the installation,
operation, and maintenance of structural controls and treatment devices.
Detention: The process of temporarily collecting and holding back stormwater for later release to receiving
waters.
Detention Storage: Surface water moving over the land is in Detention Storage. Surface water allowed to
temporarily accumulate in ponds, basins, reservoirs or other types of holding facility and that is ultimately returned
to a Watercourse or other drainage system as runoff is in Detention Storage.
Dike: (1) Usually an earthen bank alongside and parallel with a river or open channel to restrict overflow (See
Levee). (2) An asphalt concrete berm along the edge of a shoulder.
Stormwater Management Plan (SWMP)
Kum & Go Store #0951
SWMP Template REV April 2019
Dissipate: Expend or scatter harmlessly, for example reducing the energy of moving water to a non-harmful flow
rate.
Disturbed Areas: Areas that have been purposefully cleared, grubbed, excavated, or graded by the Contractor;
ground surface that has been disrupted by Construction Activities, including construction access/roads, staging,
and storage sites producing significant areas of exposed soil and soil piles.
Ditch: Small man-made channel, usually unlined.
Diversion: (1) The change in character, location, direction, or quantity of flow of a natural drainage course (a
deflection of flood water is not a Diversion). (2) Draft of water from one channel to another. (3) Interception of
runoff by works that discharge it through man-made channels.
Drainage Area (Drainage Basin): An area of the earth’s surface upon which falling precipitation flows to a given
point.
Energy Dissipator: A structure for the purpose of slowing the flow of water and reducing the erosive forces
present in any rapidly flowing body of water.
Environmental Protection Agency (EPA): Federal agency that issued the regulations to control pollutants in
stormwater runoff discharges (The Clean Water Act and NPDES permit requirements).
Erosion and Sediment Control Plan: A plan designed to control erosion by providing CMs that protect the soil
surface and prevent soil particles from being detached by wind or water, manages runoff by diverting sediment
laden water to sediment control CMs, provides sediment control CMs that trap soil particles after they have been
detached and transported by wind or water and prevents those particles from being discharged from the site, and
manages potential pollutants found in construction materials from being discharged from the site via stormwater
discharges.
Erosion Control: Any practice that protects the soil surface and prevents the soil particles from becoming
detached by rainfall or wind. This includes vegetation, such as grasses, and other materials, such as straw, fiber,
stabilizing emulsion, protective blankets, etc., placed to stabilize areas disturbed by grading and operations
intended to reduce loss of soil due to the action of water or wind, and prevent water pollution.
Filter Fabric: An engineering fabric (geotextile) placed between the backfill and supporting or underlying soil
through which water will pass and soil particles will be retained.
Final Stabilization:
The condition reached when all ground surface disturbing activities at the site have been completed, and for all
areas of ground surface disturbing activities where a uniform vegetative cover has been established with an
individual plant density of at least 70 percent of pre-disturbance levels, or equivalent permanent, physical erosion
reduction methods have been employed.
Hazardous Substances: For purposes of Section 311 of the CWA, the EPA identifies Hazardous Substances by
specific listings in the federal implementing regulations (currently found at 40 C.F.R. part 116). There are
approximately 300 chemicals currently identified as Hazardous Substances by the EPA.
Hazardous Waste: Wastes (which includes materials, products, and substances that have been discarded or
disposed of) which are classified as Hazardous Wastes by the EPA or the appropriate state environmental
agency, typically by being listed as a Hazardous Waste, or being shown to be hazardous by characteristic,
pursuant to the Hazardous Waste Standards.
Hazardous Waste Standards: The federal Resource Conservation and Recovery Act, as amended (RCRA),
which is codified as a part of the federal Solid Waste Disposal Act, 42 U.S.C. 6901 et seq., and rules promulgated
Stormwater Management Plan (SWMP)
Kum & Go Store #0951
SWMP Template REV April 2019
by EPA pursuant to RCRA, and similar and comparable laws, rules and other standards regulating Hazardous
Wastes and promulgated by state, regional, and local environmental authorities having jurisdiction over
Hazardous Wastes.
Kum & Go’s Site Development Manager: The Kum & Go employee or authorized representative identified by
Kum & Go as the project manager for the Project.
Mulch: A natural or artificial layer of plant residue or other material that covers the land surface and conserves
moisture, holds soil in place, aids in establishing vegetation, and reduces temperature fluctuations.
MS4 or Municipal Separate Storm Sewer System: Any conveyance or system of conveyances (including roads
with drainage systems, municipal streets, catch basins, curbs, gutters, Ditches, manmade channels, or storm
drains) that (i) is owned and operated by a state or local government entity (ii) is designed or used for collecting or
conveying public stormwater (iii) is not used as a combined sewer (i.e., a system that combines municipal sewage
with stormwater runoff) and/or (iv) is not part of a publicly owned treatment works.
National Pollutant Discharge Elimination System (NPDES): EPA’s program to control the discharge of
pollutants to waters of United States. NPDES is a part of the federal CWA, which requires point and non-point
source discharges to obtain permits. These permits are referred to as NPDES permits.
Notice of Intent (NOI): A formal notice to the EPA or a state agency having delegated NPDES authority that a
construction project seeking coverage under a Construction General Permit is about to begin. The NOI provides
information on the owner, location, and type of project, and certifies that the permittee will comply with conditions
of the Construction General Permit. Unlike a permit application, the NOI is a notice provided to the regulatory
agency within a specified time prior to initiation of Construction Activity and no approval is required. Some local
permits may require submittal of a Notice of Registration or Authorization (NOR, NOA) or a plan approval
application in lieu of filing a NOI with the state or EPA.
Notice of Termination (NOT): A formal notice to the EPA or authorized state agency for General Permit site
terminating coverage under the permit. This may also be known as Notice of Discontinuation (NOD).
Off-Site Drainage: Flow of water that originates outside the property.
On-Site: Flow of water that originates inside the property.
Oil: For purposes of Section 311 of the CWA, the EPA defines Oil to include not only petroleum-based products
(such as fuel oil, gasoline, motor oil, oil refuse, and sludge) but also mineral and vegetable oils.
Operator: The party that has operational control over day-to-day activities at a project site which are necessary to
ensure compliance with the permit. This party is authorized to direct individuals at a site to carry out activities
required by the permit.(e.g. the general contractor)
Operator’s Engineer: Shall be that person or entity retained by an Operator to design and oversee the
implementation of the SWMP.
Operator’s Project Manager: This project manager designation is intended to be a generic term that describes
the role of (i) the Kum & Go Site Development Manager, (ii) the Contractor’s Project Manager, and/or (iii) any
developer’s project manager(s), as the context requires. Where a provision refers to an “Operator’s Project
Manager”, the intent is to make the provision applicable to the project managers for all Operators associated with
the Project
Owner: The party that has overall control of the activities and that has funded the implementation
of the construction plans and specifications. This is the party with ownership of, a long term lease
of, or easements on the property on which the construction activity is occurring (e.g., the
developer).

Kum & Go Store #0951
SWMP Template REV April 2019
Permittee(s): The owner and operator named in the discharge certification issued under this permit for the
construction site specified in the certification.
Project: Any construction site in the United States where Kum & Go has a contract (as defined in the SDA
Contract) for the construction of a convenience store, fuel dispensing canopy, or other facilities.
Qualified Stormwater Manager: An individual knowledgeable in the principles and practices of
erosion and sediment control and pollution prevention, and with the skills to assess conditions at
construction sites that could impact stormwater quality and to assess the effectiveness of
stormwater controls implemented to meet the requirements of this permit.
Retention: The holding of runoff in a basin without release except by means of evaporation, infiltration, or
emergency bypass.
Sediment Control: Any practice that traps soil particles after they have been eroded and moved by wind or
water.
Site Map: The Site Map usually consists of the Phase I and Phase II Erosion and Sediment Control Drawings and
include CM 1) construction site boundaries, 2) flow arrows that depict stormwater flow directions on-site and
runoff direction, 3) all areas of ground disturbance including areas of borrow and fill, 4) areas used for storage of
soil, 5) locations of all waste accumulation areas, including areas for liquid, concrete masonry, and asphalt, 6)
locations of dedicated asphalt, concrete batch plants and masonry mixing stations, 7) locations of all structural
control measures, 8) locations of all non-structural control measures, 9) locations of springs, streams, wetlands
and other state waters, including areas that require pre-existing vegetation be maintained within 50 feet of a
receiving water, where determined feasible in accordance with Part1.B.a.i.(d) of the CGP, and 10) locations of all
stream crossings located within the construction site boundary. The Site Map will be used to record the locations
of the Job Trailer, Sanitary Waste Facilities, Solid Waste Facilities, Fuel Storage Areas, Equipment Service Areas,
and Concrete Washout. The Site Map will be used to identify previous and present locations of these items. The
Site Map will be used to record and document any plan amendments or modifications and will be used visually
depict all amendments identified on SWMP Amendment Log, Appendix G. The Site Map will be updated daily to
record where Final Stabilization has occurred.
Stormwater Management: The recognition of adverse drainage resulting from altered runoff and the solutions
resulting from the cooperative efforts of public agencies and the private sector to mitigate, abate, or reverse those
adverse results.
Stormwater Pollution Prevention Plan (SWMP): A plan document prepared in accordance with good
engineering practices that identifies all potential sources of pollution which may reasonably be expected to affect
the quality of stormwater discharges from the construction site, that describes practices used to reduce pollutants
in stormwater discharges, and that assures compliance with the terms and conditions of the Construction General
Permit. The SWMP must be implemented as written from commencement of the Construction Activity until Final
Stabilization is complete.
SWMP Ledger: The Ledger is where all SWMP information is stored including reports and records as
accumulated during construction of the project. The Ledger must always be up-to-date with the latest plans and
criteria including all records developed during the construction activity. The Ledger must be available during
normal business hours for viewing by the governmental agencies having jurisdiction and any Kum & Go’s
personnel.
Swale: A shallow, gentle depression in the earth’s surface. This tends to collect the waters to some extent and is
considered, in a sense, as a drainage course, although waters in a Swale are not considered stream waters.
Terrace: Berm or bench-like earth embankment, with a nearly level plain bounded by rising and falling slopes.
Topsoil: The fertile, uppermost part of the soil containing significant organic matter largely devoid of debris and
rock and often disturbed in cultivation.
Stormwater Management Plan (SWMP)
Kum & Go Store #0951
SWMP Template REV April 2019
Total Maximum Daily Load (TMDL): A process established by the CWA guiding the application of state water
quality standards to individual water bodies and watersheds where these water bodies have been previously
established as impaired (303(d) Impaired Waterway) by defining the amount of a particular pollutant that a water
body can absorb on a daily basis without violating applicable water quality standards. Once this load is
determined, the regulatory agency allocates a portion to each source of that pollutant within a particular
watershed.
Total Suspended Solids (TSS): Particles that are suspended in water. Suspended solids in water reduce light
penetration in the water column, can clog the gills of fish and invertebrates, and are often associated with toxic
contaminants because organics and metals tend to bind to particles.
Velocity: The rate of motion of objects or particles, or of a stream of particles.
Watercourse: A defined channel with bed and banks within which water flows, either continuously or in season. A
Watercourse is continuous in the direction of the flow and may extend laterally beyond the definite banks to
include overflow channels contiguous to the ordinary channel. The term does not include artificial channels such
as canals and drains, except natural channels trained or restrained by the works of man. Neither does it include
depressions or Swales through which surface nor errant waters pass.
Water of the United States: (a) All waters that are currently used, were used in the past, or may be susceptible
to use in interstate or foreign commerce, including all waters that are subject to the ebb and flow of the tide; (b) All
interstate waters, including interstate Wetlands; (c) All other waters such as intrastate lakes, rivers, streams
(including intermittent streams), mudflats, sandflats, Wetlands, sloughs, prairie potholes, wet meadows, playa
lakes, or natural ponds, the use, degradation, or destruction of which would affect or could affect interstate or
foreign commerce including any such waters: (1) that are or could be used by interstate or foreign travelers for
recreational or other purposes; (2) from which fish or shellfish are or could be taken and sold in interstate or
foreign commerce, or (3) that are used or could be used for industrial purposes by industries in interstate
commerce; (d) All impoundments of waters identified in paragraphs (a) through (d) of this definition; (e) The
territorial sea; and (f) Wetlands adjacent to waters (other than waters that are themselves Wetlands) identified in
paragraphs (a) through (e) of this definition. Waste treatment systems, including treatment ponds or lagoons
designed to meet the requirements of CWA (other than cooling ponds as defined in 40 CFR 423.11 (m) that also
meet the criteria of this definition) are not Waters of the United States. This exclusion applies only to manmade
bodies of water that neither were originally created in Waters of the United States (such as disposal area in
wetlands) nor resulted from the impoundment of Waters of the Unites States.
Wetland: Wetlands are areas that may be inundated or saturated by surface or ground water at a frequency and
duration sufficient to support, and that, under normal circumstances, do support, a prevalence of vegetation
typically adapted to saturated conditions. Functionally, a Wetland must demonstrate the characteristics of
Wetland Hydrology, hydric soils, and hydrophytic vegetation, in accordance with the 1987 Corps of Engineers
Wetlands Delineation Manual. In order to ensure compliance with federal and state requirements for disturbance
of Wetlands, it is advisable to have the site inspected by a Wetlands expert to identify and delineate potential
Wetlands. Wetlands on a site should be delineated, surveyed, and depicted on a map approved by staff of the
Corps of Engineers. A signed map is called a jurisdictional determination and is valid for a period of time, typically
3 to 5 years. Wetlands do not all appear to be swampy or marshy all the time and, in many cases, will never
appear swampy or marshy.
303(d) Impaired Waterway: A waterway listed by the state with the EPA under Section 303(d) of the CWA as a
water failing to meet water quality standards in spite of full compliance by dischargers with all conditions and
limitations in NPDES permits and all applicable non-point source controls.
