1.0 INTRODUCTION
This report presents the Erosion and Sediment Control of the construction plans for the Affinity
Fort Collins project, located in the southeast quarter of Section 32, Township 7 North, Range 68
West of the 6th Principal Meridian in the City of Fort Collins, Larimer County, Colorado. More
specifically, the Affinity Fort Collins site is an 8.35 acre property that is currently undeveloped and
is being used for irrigated agricultural purposes. The site is zoned HC (Harmony Corridor District)
and will support apartments and associated amenities once developed. The proposed use of the site
is a three-story multi-family apartment complex and associated amenities. The proposed concept
includes one main apartment building with separate garden area, pool building, and parking and
garages around the perimeter of the site.
This report was prepared in compliance with the Colorado Water Quality Control Act, the Federal
Water Pollution Control Act, and City of Fort Collins and Urban Drainage and Flood Control
District standards.
This plan serves as a consolidated document for information on water quality protection for the
subject site and areas immediately adjacent. It should also be noted that this plan is a living
document that will need to be updated and maintained throughout the construction
process. The intent of this plan is to provide the contractor a tool to consolidate records, logs,
permits, applications, etc. as well as guidance on water quality protection. The plan incorporates
elements that can be found in the contract plans and specifications as well as the following:
x City of Fort Collins Storm Drainage Criteria Addendum to the Urban Storm Drainage Criteria
Manuals
x Colorado Department of Transportation Erosion Control and Stormwater Quality Guide
x Urban Drainage and Flood Control District Urban Storm Drainage Criteria Manual Volume 3 –

2.0 SITE DESCRIPTION
2.1 SITE LOCATION
Affinity Fort Collins is located in the southeast quarter of Section 32, Township 7 North, Range 68
West of the 6th Principal Meridian in the City of Fort Collins, Larimer County, Colorado. More
specifically, the Affinity Fort Collins site is an 8.35 acre property that is currently undeveloped and
is being used for irrigated agricultural purposes. The site is located north of Harmony Road
between Ziegler Road and Timberline Road in Fort Collins, as shown on the Vicinity Map in Figure
1.
2.2 GENERAL PROJECT DESCRIPTION
The site is zoned HC (Harmony Corridor District) and will support apartments and associated
amenities once developed. The proposed use of the site is a three-story multi-family apartment
complex and associated amenities. The proposed concept includes one main apartment building
with separate garden area, pool building, and parking and garages around the perimeter of the site.
The proposed main building is 167,538 total square feet, with 153 dwelling units.
2.3 EXISTING SITE DESCRIPTION
The vegetative cover on the site generally consists of natural grasses and weeds. Existing vegetation
covers roughly 90 percent of the ground surface. The existing site generally slopes from the
southwest to the northeast with slopes ranging between 0.60% and 2.5%. The site currently drains
to the northeast and east. Runoff sheet flows off the east side of the property and a portion of the
runoff flows to a point in the north.
2.4 SOIL AND SUBSURFACE CONDITIONS
The Affinity Fort Collins site soils consist of loamy soil, predominately Nunn clay loam. Nunn clay
loam belongs to hydrologic soils Group C. Group C soils have a slow infiltration rate when
thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement
of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water
transmission. Nunn clay loam with 0-3 percent slopes generally has a combined surface layer
thickness of approx. 30 inches. Runoff is moderately high, and the hazards of wind erosion are
moderately low. Supporting figures can be found in Appendix F.
The Contractor's preferred method of managing stormwater and groundwater may require a
Construction Dewatering Permit from CDPHE, or additional permits. Dewatering operations shall
not be in violation of Colorado Division of Water Resources rules and regulations regarding
exposure of groundwater. Forms are included in Appendix A.
Erosion and Sediment Control Plan for Affinity Fort Collins
Page 3
2.5 WETLANDS, RECEIVING WATERS, AND ENDANGERED SPECIES
The site is shown on FEMA FIRM panel 08069C0994F, dated December 19, 2006. The site lies
within Zone X, areas which are determined to be outside the 0.2% annual chance floodplain,
presented in as Figure 2.
There are no existing irrigation ditches or wetlands associated with the site. In addition, the
project is not bordered by any existing wetlands. Therefore, no negative impacts to the wetlands
onsite or offsite are anticipated due to the construction of this project. There are no major
drainage ways located within or immediately adjacent to the site.
2.6 DESCRIPTION OF CONSTRUCTION ACTIVITY
The proposed project consists of the construction of a three-story multi-family apartment complex
and associated amenities. The project will encompass approximately 8.35 acres of disturbance.
The project will include earthwork and embankment fill; vertical construction, grading and asphalt
paving at the proposed parking lots; and onsite detention ponds with an outlet structure and pipes.
The Contractor will be responsible for implementing and maintaining the erosion and sediment
control measures described in this document and the accompanying design drawings. The
Contractor may designate these tasks to certain subcontractors as he sees fit, but the ultimate
responsibility for implementing these controls and their proper function at each phase of the
project remains with the Contractor. Under this plan, any part of the proposed drainage
improvements may be under construction simultaneously or at separate times so long as the
necessary pollution prevention practices described in more detail in the report that follows are
followed and implemented properly.
2.7 PROPOSED SEQUENCE OF MAJOR ACTIVITIES
1. Install vehicle tracking control at the construction entrance(s). Install perimeter fencing/erosion
control measures, including silt fence where shown. Install concrete washouts.
2. Perform earthwork and site improvements. Maintain erosion control features for interim
phase.
3. Install seeding and mulching, landscaping and final stabilization.
4. Clean up. Removal of BMPs.
2.8 POTENTIAL POLLUTANTS
During construction of the new facilities, onsite storm water may be contaminated with pollutants
that could include soil sediments, slurry from saw cutting of concrete and asphalt, the washing of
exposed aggregate and concrete mix trucks, equipment fueling, washing and maintenance
operations, pavement washing and/or sealing and other related activities. These activities are
described in more detail in Section 3.6, Materials Management.
Erosion and Sediment Control Plan for Affinity Fort Collins
Page 4
Potential sources of non-stormwater discharges include uncontaminated groundwater, construction
dewatering, concrete washout, vehicle washing and maintenance operations, and pavement washing.
If dewatering is to be discharged offsite, a separate state CDPHE dewatering permit will be
required. However, groundwater is not expected to be encountered.
Erosion and Sediment Control Plan for Affinity Fort Collins

3.0 CONTROLS
3.1 CONTROLS OVERVIEW
During construction, several controls and measures shall be implemented under the direction of the
General Contractor to prevent offsite discharge of contaminated storm water. Controls for this
project include erosion, sedimentation, stabilization, and other Best Management Practices (BMPs).
Specifications and engineering drawings for the selected BMPs can be found on the drawings
included in the back pocket of this report.
The contractor shall comply with the attached plans and guidelines as a minimum. Field conditions
and unforeseen circumstances will dictate modifications to or additions to this Storm Water
Management Plan. Where storm water pollution potential exists, appropriate preventative
measures must be utilized and documented, whether such measures are identified in this report or
not.
3.2 EROSION AND SEDIMENT CONTROLS
The objective of erosion control is to limit the amount of erosion occurring on disturbed areas
until the site is stabilized. The objective of sediment control is to capture the soil that has been
eroded before it leaves the construction site. Despite the use of both erosion and sediment
control measures, it is recognized that some sediment could remain in runoff leaving the
construction site or result in sediment accrual within the existing storm drainage system south of
the site. This should be minimized to the maximum extent practicable.
During all phases of construction the General Contractor shall in the event of a substantial rainfall
event, provide storm water collection and conveyance systems to collect and direct sediment
contaminated water to temporary sediment traps as needed to prevent offsite discharge of
sediment laden storm water. Construction shall occur in phases as much as practicable to avoid
unnecessarily exposing vegetated areas of the site. Clean storm water, generated from stabilized
and undisturbed portions of the site, will be collected and conveyed to stabilized discharges
whenever necessary to avoid contact with disturbed portions of the site. All conveyance and
collection systems will be constructed consistent with State, Federal, and local BMP requirements.
The BMPs scheduled for use during the construction of this site can be divided into Structural and
Non-Structural Practices. Section 3.3 of this report discusses the proposed structural BMPs to be
utilized. Section 3.4 discusses the non-structural practices.
3.3 STRUCTURAL PRACTICES
Structural BMPs are structural site management practices that will minimize erosion and sediment
transport. Such practices may include straw bales, silt fences, earth dikes, drainage swales, sediment
traps and basins, inlet protections, outlet protection, etc. The goal of structural BMPs on this
Erosion and Sediment Control Plan for Affinity Fort Collins
Page 6
project is to protect areas downstream of the site from turbid water, sediment, oils and other
contaminants, which may mobilize during storm water flows. The contractor is recommended to
utilize the structural BMPs identified in the erosion control plans but may be required to implement
additional controls as necessary. The recommended BMPs are detailed in the Erosion Control
Plans and are described in more detail as follows, including additional BMPs as the contractor may
see fit:
Silt Fence:
x A temporary vertical barrier of filter fabric attached to and supported by posts and
entrenched into the ground.
x Utilized to intercept sediment from disturbed areas during construction operations.
x Used to filter shallow sheet flow.
x Typically used along the toe of fills, in transition areas between cut and fills, and adjacent to
streams.
x Generally installed prior to or immediately following land-disturbance activity.
x Shall be inspected periodically and after each rain or snowfall event and repaired when
necessary. Sediment shall be removed from behind the fence when it accumulates to one-half
the exposed fabric height. Sediments removed must be properly disposed.
Sediment Control Log:
x A temporary vertical barrier of rolled natural materials such as straw or other fibrous material
(also known as wattles).
x Utilized to intercept sediment from disturbed areas during construction operations.
x Used to filter shallow sheet flow.
x Typically used as perimeter control inlet protection, on disturbed slopes, along the toe of fills, in
transition areas between cut and fills, and adjacent to streams.
x Generally installed prior to or immediately following land-disturbance activity.
x Shall be inspected periodically and after each rain or snowfall event and repaired when
necessary. Sediment shall be removed from behind the fence when it accumulates to one-half
the exposed log height. Sediments removed must be properly disposed.
x Utilized as a temporary feature.
Rock Sock:
x A temporary vertical barrier of rolled wire- or geotextile-enclosed gravel or rock (also known
as curb socks).
x Utilized to intercept and filter sediment in gutters during construction operations and used as
inlet protection. Placed angling upstream in the curb to promote pooling and settling out of
sediment.
x Used as perimeter control and does not require staking.
x Very susceptible to displacement and damage from vehicular traffic. Requires frequent
inspection.
x Generally installed prior to or immediately following land-disturbance activity.
Erosion and Sediment Control Plan for Affinity Fort Collins
Page 7
x Shall be inspected periodically and after each rain or snowfall event and repaired when
necessary. Sediment shall be removed from behind the sock when it accumulates to one-half
the exposed fabric height. Sediments removed must be properly disposed.
Inlet Protection:
x A temporary barrier across or around a storm drain drop inlet, a curb inlet, or a culvert inlet.
x Utilized to intercept and filter sediment-laden runoff and prevent it from entering storm
drainage systems.
x Not to be utilized in place of a sediment-trapping device. Used as a secondary control device.
x Do not use where ponded water might flow onto the roadway.
x Blocking of the inlet should not be watertight.
x Generally installed prior to land-disturbance activity on existing inlets and immediately after the
construction of new inlets.
x Shall be inspected periodically and after each rain or snowfall event and repaired when
necessary. Accumulated sediment shall be removed and properly disposed.
x Utilized as a temporary feature.
Vehicle Tracking Control / Construction Entrance:
x A temporary stabilized layer of aggregate underlined with geotextile or gravel located where
traffic enters or exits the construction site.
x The structure shall be constructed prior to any construction activity and maintained daily.
x Stone shall be added and repairs performed as conditions require.
x When mud is present and not easily removed by a tracking pad, tire washing should be
implemented as needed. Tire washing operations should occur near the construction exit on a
stabilized stone pad. Implementation of a tire washing area should include provisions for
collecting wash water and directing it to an onsite pond.
Concrete Washout Area:
x Concrete waste management involves designating and properly managing a specific area of the
construction site as a concrete washout area.
x The use of the washout site should be temporary (less than 1 year).
x The washout site should be not be located in an area where shallow groundwater may be
present, such as near natural drainages, springs, or wetlands.
x Do not locate an unlined washout area within 400 feet of any natural drainage pathway or water
body or within 1,000 feet of any wells or drinking water sources.
x Remove concrete waste in the washout area, as needed to maintain BMP function.
x Upon termination of use of the washout site, accumulated solid waste, including concrete waste
and any contaminated soils, must be removed from the site to prevent on-site disposal of solid
waste. If the wash water is allowed to evaporate and the concrete hardens, it may be recycled.
Erosion Control Blanket:
Erosion and Sediment Control Plan for Affinity Fort Collins
Page 8
x A temporary degradable rolled erosion control product composed of processed natural or
polymer fibers which are mechanically, structurally or chemically bound together to form a
continuous matrix to provide erosion control and facilitate vegetation establishment. ECBs can
be further differentiated into rapidly degrading single-net and double-net types or slowly
degrading types.
x RECPs should be installed according to manufacturer’s specifications and guidelines
x Check for general signs of erosion, including voids beneath the mat. If voids are apparent, fill the
void with suitable soil and replace the erosion control blanket, following the appropriate staking
pattern.
x Check for damaged or loose stakes and secure loose portions of the blanket.
Check Dam:
x Check dams are temporary grade control structures placed in drainage channels to limit the
erosivity of stormwater by reducing flow velocity. Check dams are typically constructed from
rockand wire gabion.
x Check dams are used as temporary grade control facilities along waterways until final
stabilization is established, along permanent swales that need protection prior to installation of
a non-erodible lining, along temporary channels, ditches or swales that need protection where
construction of a non-erodible lining is not practicable, and should be used in areas subject to
high flow velocities.
x When reinforced check dams are used, install erosion control fabric under and around the
check dam to prevent erosion on the upstream and downstream sides. Each section of the dam
should be keyed in to reduce the potential for washout or undermining.
x Replace missing rocks causing voids in the check dam. If gravel bags or sandbags are used,
replace or repair torn or displaced bags.
x Remove accumulated sediment, as needed to maintain BMP effectiveness.
x Check dams constructed in permanent swales should be removed when perennial grasses have
become established, or immediately prior to installation of a non-erodible lining.
Erosion and Sediment Control Plan for Affinity Fort Collins
Page 9
Rough Cut Street Control:
x Rough cut street controls are rock or earthen berms placed along dirt roadways that are under
construction or used for construction access. These temporary berms intercept sheet flow and
divert runoff from the roadway, and control erosion by minimizing concentration of flow and
reducing runoff velocity.
x Use on temporary dirt construction roadways that have not received roadbase and roadways
under construction that will not be paved within 14 days of final grading, and that have not yet
received roadbase.
x Rough cut street controls are designed to redirect sheet flow off the dirt roadway to prevent
water from concentrating and eroding the soil. These controls consist of runoff barriers that are
constructed at intervals along the road.
x Inspect street controls for erosion and stability. If rills are forming in the roadway or cutting
through the control berms, place the street controls at shorter intervals. If earthen berms are
used, periodic recompaction may be necessary. When rock berms are used, repair and/or
replace as necessary when damaged. Street controls may be removed 14 days prior to road
surfacing and paving.
Earth Dike:
x Earth dikes and drainage swales are temporary storm conveyance channels constructed either
to divert runoff around slopes or to convey runoff to additional sediment control BMPs prior to
discharge of runoff from a site.
x When earth dikes are used to divert water for slope protection, the earth dike typically consists
of a horizontal ridge of soil placed perpendicular to the slope and angled slightly to provide
drainage along the contour. The dike is used in conjunction with a swale or a small channel
upslope of the berm to convey the diverted water.
x All dikes or swales receiving runoff from a disturbed area should direct stormwater to a
sediment control BMP such as a sediment trap or basin.
Erosion control measures are the responsibility of the General Contractor to inspect and maintain.
Any existing erosion control devices that are removed in order to complete the construction of the
utilities shall be replaced immediately following the construction that required its removal unless
directed otherwise by the construction plans.

3.4 NON-STRUCTURAL PRACTICES
Non-Structural BMPs are both interim and permanent stabilization practices. Such practices may
include temporary seeding, permanent seeding, mulching, geotextiles, sod stabilization, vegetative
buffer strips, tree protection, preservation of mature vegetation, etc. The non-structural BMPs that
may be utilized on the subject site are described in more detail as follows:
Temporary and Permanent Seeding:
x Soil preparation, seeding, mulch tackifier and/or mulching shall be required for all disturbed
areas that are not surfaced.
x Exposed soils, which are not part of the active grading and/or construction activity, shall be
stabilized.
x Seeded areas shall be inspected frequently. If the seeded areas fail to establish, provide adequate
ground coverage. If seeded areas are disturbed, the area should be re-seeded.
x Permanent landscaping and vegetative cover is depicted on the Erosion Control plans.
Mulching:
x Application of plant residues to the soil surface. Typical mulching material includes certified
weed free hay or straw, certified under the Colorado Department of Agriculture Weed Free
Forage Certification Program as regulated by the Weed Free Forage Act, Title 35, Article 27.5,
CRS and wood cellulose fiber.
x Utilized in combination with mulch tackifier for temporary erosion control (i.e., incomplete
slopes, detour slopes, stockpiles).
x Utilized in combination with mulch tackifier for temporary erosion control on slopes when
seeding is not allowed due to seasonal constraints.
x Used to cover permanent or temporary seed areas. Hydromulch shall not be done in the
presence of free surface water.
x Inspect frequently and reapply mulching in areas where the mulching has been loosened or
removed. Mulch tackifier must be applied with additional applications of mulching.
Mulch Tackifier:
x An organic soluble powder adhesive used as a water slurry to adhere native hay, straw,
hydromulch, or seed to a surface and together.
x Used to cover disturbances as temporary cover for wind erosion.
x Mulch movement indicates poor application and procedure mixture.
x Proper application will bond mulch material together and to soil.
x Inspect by touching mulch surface to determine if adhesion has occurred.
Maintain Existing Vegetation:
x Existing vegetation should be preserved where possible to prevent the migration of sediment.
x Should be inspected regularly.
x Establish and maintain buffers.
Erosion and Sediment Control Plan for Affinity Fort Collins
Page 11
x Areas beginning to show signs of erosion or soil transport may require additional emergency
BMPs.
Grading/Stockpile Techniques:
x Soil surface roughening, terracing and rounding at tops of cuts, transitions and roadway ditches
to facilitate plant establishment and minimize erosion.
x Utilized to temporarily stabilize disturbed areas and protect from wind and water erosion
immediately after grading activities have ceased.
x Used as a temporary practice during construction.
x Inspection and maintenance must be provided periodically and after each rain or snowfall event
that causes runoff to ensure roughened state is maintained.
x Rills developed should be filled and the area re-graded immediately.
Surface Roughening:
x Tracking, scarifying, imprinting, or tilling a disturbed area to provide temporary stabilization of
disturbed areas.
x Surface roughening can be used to provide temporary stabilization of disturbed areas, such as
when revegetation cannot be immediately established due to seasonal planting limitations.
x Surface roughening is not a stand-alone BMP, and should be used in conjunction with other
erosion and sediment controls.
Spill Prevention:
x Adhering to the general practices described herein so as to minimize the potential for chemical
and pollutant spills.
Sweeping:
x Public and private roadways shall be kept clear of accumulated sediment. Bulk clearing of
accumulated sediment shall not include flushing the area with water. Sediment will be shoveled
and/or swept from the street and disposed of in a manner that prevents contamination of storm
water or surface water runoff.
Dust Control:
x Wind erosion shall be controlled on the site by sprinkling and other appropriate means.
x Stockpiles and disturbed earth throughout the site may be watered regularly or as designated by
the General Contractor to eliminate/control wind erosion.
Education to Crew and Subcontractors:
x Crews shall be made aware of the requirements herein and shall be instructed in the spill
response procedures outlined in this report.
Trash Control:
Erosion and Sediment Control Plan for Affinity Fort Collins
Page 12
x The site shall be made free of any trash debris, construction or otherwise, and no such material
shall leave the site at any time.
Sanitary Waste Control:
x Onsite sanitary facilites/chemical toilets shall be located away from waterways. Secondary
containment shall be provided for sanitary wastes at all times.
Good Housekeeping Practices:
x Implement construction site good housekeeping practices to prevent pollution associated with
solid, liquid and hazardous construction-related materials and wastes.
x Provide for waste management.
x Establish proper building material staging areas.
x Designate paint and concrete washout areas.
x Establish proper equipment/vehicle fueling and maintenance practices.
x Control equipment/vehicle washing and allowable non-stormwater discharges.
x Develop a spill prevention and response plan.
3.5 OTHER CONTROLS
Vehicle Tracking Control / Construction Entrance:
x A temporary stabilized layer of aggregate underlined with geotextile or gravel located where
traffic enters or exits the construction site.
x The structure shall be constructed prior to any construction activity and maintained daily.
x Stone shall be added and repairs performed as conditions require.
x When mud is present and not easily removed by a tracking pad, tire washing should be
implemented as needed. Tire washing operations should occur near the construction exit on a
stabilized stone pad. Implementation of a tire washing area should include provisions for
collecting wash water and directing it to an onsite pond.
Tracking of Sediment onto Roads and Streets:
x The main construction accesses will be established on existing access road near the northeast
edge of the site. Other phased construction entrances may be utilized as depicted on the
Erosion Control plan. The accesses will be stabilized to prevent tracking of sediment offsite. All
construction vehicles entering or exiting the site will be limited to these locations.
x Public and private roadways shall be kept clear of accumulated sediment. Bulk clearing of
accumulated sediment shall not include flushing the area with water. Sediment will be shoveled
and or swept from the street and disposed of in a manner that prevents contamination of storm
water or surface water runoff.
Control Practices for Wind Erosion:
x Wind erosion shall be controlled on the site by sprinkling and other appropriate means.
Erosion and Sediment Control Plan for Affinity Fort Collins
Page 13
x Stockpiles and disturbed earth throughout the site may be watered regularly or as designated by
the General Contractor to eliminate/control wind erosion.
3.6 MATERIALS MANAGEMENT
Potential Pollution Sources
It is not anticipated that construction of this project will utilize any abnormal or atypical hazardous
materials. The construction site will operate much like other typical excavation and grading
construction projects. The following materials or substances may be expected to be present onsite
during any phase of construction:
• Concrete/Additives/Wastes • Cleaning solvents
• Detergents • Petroleum based products
• Paints/Solvents • Pesticides
• Acids • Fertilizers
• Solid and construction wastes • Sanitary wastes
• Soil stabilization additives
Activities on the site that may have an impact on stormwater include the following:
• Vehicle fuels and fluids
• Equipment and/or vehicle washing
• Fertilizers, chemicals, or other material storage
• Waste storage or disposal
• Off-site and roadway vehicle tracking
• Loading/unloading areas
• Concrete truck washout
• Chemical toilets and human waste
Fueling
Vehicle fueling is not expected to be done on-site, and there is no designated area for fueling at this
time. It will be the responsibility of the contractor to designate a fueling area if needed and take the
appropriate actions to insure that no pollution of the stormwater occurs. Fueling areas shall be
located a minimum of 100 feet from all drainage courses whenever possible. Fueling areas shall be
enclosed by a 12-inch high compacted earthen ridge capable of retaining potential spills. If the
fueling area is located on soil, the area shall be covered with a non-porous lining to prevent soil
contamination.
It will be the responsibility of the contractor to designate a concrete truck cleaning area and take
the appropriate actions to insure that no pollution of the stormwater occurs. Cement truck
Erosion and Sediment Control Plan for Affinity Fort Collins
Page 14
cleaning areas shall be located a minimum of 100 feet from all drainage courses whenever possible.
The area shall limit the travel of wash water from the area. The area shall be cleaned up of all
washed cement on an as necessary basis.
As construction progresses, specific areas shall be designated for vehicle maintenance and refueling,
material and waste storage, construction equipment staging, and bathroom facilities as needed.
Management measures and procedures for these facilities are discussed later in the plan. The
contractor shall mark the location of these facilities on the Erosion Control Plans located within
Appendix G of this report.
Pollution Prevention Measures
Pollution prevention measures shall be utilized to prevent construction materials with the potential
of polluting stormwater, such as those listed above, from coming in contact with runoff. Measures
include good housekeeping and proper disposal of construction and demolition debris, equipment
fuel, lubricants, paints and solvents, asphalt, concrete, topsoil and other materials, as well as
controls which prevent sediments from being tracked off-site by construction vehicles, and proper
control of any non-stormwater flows on-site.
As previously stated, BMPs are schedules of activities, prohibitions of practices, maintenance
procedures, and other management practices to prevent or reduce pollution of public waters.
BMPs also control site runoff, spillage or leaks, sludge or waste disposal, or drainage from raw
material storage. With regard to construction, these may include structural controls and
nonstructural practices that are designed to prevent pollutants from entering water or direct the
flow of water away from potential sources of pollution.
For construction sites, there are three main types of BMPs, those that prevent erosion and
sediment transport, others that prevent pollutants from construction materials from mixing with
stormwater, and those that trap pollutants before they can be discharged. BMPs for most common
construction materials and wastes with the greatest potential for adversely affecting stormwater
quality are as follows:
BMPs for Construction Waste:
x Select a designated waste collection area onsite, located a minimum of 100 feet from all drainage
courses whenever possible.
x Whenever waste is not stored in a non-porous container, it shall be in an area enclosed by a 12-
inch high compacted earthen ridge.
x If the enclosed waste area is located on porous soil, the area shall be covered with a non-
porous lining to prevent soil contamination.
x Provide an adequate number of containers with lids or covers that can be placed over the
containers prior to rainfall. Whenever precipitation is predicted, the waste shall be covered with
a non-porous cover, anchored on all sides to prevent its removal by wind, in order to prevent
precipitation from leaching out potential pollutants from the waste.
Erosion and Sediment Control Plan for Affinity Fort Collins
Page 15
x When possible, locate containers in a covered area.
x Arrange for waste collection before containers overflow.
x If a container does spill, provide cleanup immediately.
x Plan for additional containers and more frequent pickups during the demolition phase of
construction.
x Make sure that construction waste is collected, removed, and disposed of only at authorized
disposal areas.
x Check with local solid waste management agency for specific guidance.
x Trash, debris and spoils shall be properly contained at the end of each day.
BMPs for Hazardous Wastes Disposal:
x Check with local waste management authorities to determine what the requirements are for
disposing of hazardous materials.
x Use the entire product before disposing of the container.
x Do not remove the original product label from the container. It contains important
information.
x Do not mix products together unless specifically recommended by the manufacturer.
x The correct disposal of these products varies with the product utilized. Follow the
manufacturers recommended method, which is often found on the label.
BMPs for Hazardous Products management:
x Have equipment to contain and clean up spills of hazardous materials in the vicinity of where
these materials are to be stored or used.
x Contain and clean up spills immediately after they occur. Contact State or Local solid waste
regulatory agency concerning information and procedures necessary to treat or dispose of
contaminated soils.
x Keep materials in a dry covered area and elevated from the ground.
BMPs for residual concrete disposal:
x Emptying or wash out of excess concrete may be allowed on site. Excess concrete and wash
water should be disposed of in a manner that prevents contact between these materials and
stormwater discharges from the site.
x Residual concrete shall be discharged in specifically designated dike areas, which have been
prepared to prevent contact between the concrete and/or washout and stormwater discharged
from the site and/or ground water.
x The hardened residue from the dike areas shall be disposed of in the same manner as other
non-hazardous construction waste materials or may be broke up and utilized as deemed
appropriate by the contractor.
x The use of the washout area shall be temporary (less than one year).
x Washing of trucks and masonry equipment is to be performed only at a designated concrete
washout. No burying of wastes.
Erosion and Sediment Control Plan for Affinity Fort Collins
Page 16
BMPs for Stockpiles:
x In the event soil is to be stored on site, it shall be in an area located a minimum of 100 feet from
all drainage courses whenever possible.
x The soil stockpile shall be in an area enclosed by silt fence.
x Grading techniques such as surface roughening, terracing, and rounding shall be used whenever
possible.
x Should the soil stockpile be stored longer than 30 days, it shall be temporarily covered with
mulch or a tackifier.
BMPs for Sanitary/Septic Wastes:
x Sanitary or septic wastes that are generated onsite should be treated or disposed of in
accordance with State or local requirements.
x If self-contained, temporary facilities are utilized, the domestic waste haulers should be
contracted to regularly remove the sanitary and septic wastes and to maintain the facilities in
good working order.
x Any facilities to be connected to a sanitary sewer system should be properly hooked to the
sanitary sewer system to prevent illicit discharges.
x Untreated, raw sewage should never be discharged or buried onsite.
x Contact local government and State regulatory agencies to ensure the compliance with State or
local requirements.
x If sewage is being discharged to the sanitary sewer, the local treatment works authority should
be contacted.
BMPs for pesticides:
x Store pesticides in a dry covered area and elevate above the ground.
x Provide curbs or dikes to contain possible spills.
x Have measures on site to contain and clean up spills.
x Strictly follow recommended application rates and recommended application methods.
x Only a Certified Applicator shall use pesticides.
BMPs for petroleum products:
x Fueling operations shall occur in a designated area.
x Have equipment to contain and clean up petroleum spills in fuel storage areas or on board
maintenance and fueling vehicles.
x Where possible, store petroleum products and fuel vehicles in covered areas and construct
dikes to contain spills.
x Contain and clean up spills immediately.
x Use preventive maintenance for onsite equipment such as checking for and fixing gas and oil
leaks in construction vehicles on a regular basis.

Erosion and Sediment Control Plan for Affinity Fort Collins
Page 17
x Fueling equipment and area shall be fenced and valves locked to prevent vandalism.
BMPs for Fertilizers/Detergents:
x Limit the application of fertilizers to the minimum area and minimum recommended amounts.
x Reduce exposure of nutrients to storm water runoff by working the fertilizer deep into the soil.
x Apply fertilizer more frequently, but at lower application rates.
x Hydro seeding, where lime and fertilizers are applied to the ground surface in one application
should be limited, where possible.
x Limit the use of detergents onsite: wash water containing detergents should not be discharged
to the storm system.
x Implement good erosion and sediment control to help reduce the amount of fertilizers that can
leave the site as well as sediments.
x Fertilizers and detergents shall be stored in dry and covered area and elevated above the
ground.
x Berming shall be provided around the storage area to avoid contact with stormwater runoff.
Non-Storm Water Components of Discharge
Non-storm water discharges will be eliminated or reduced to the fullest extent feasible. This plan
does not cover construction dewatering. Pumping or draining groundwater that has infiltrated into
an excavation requires a general permit for construction dewatering, regardless of the size of the
project. Stormwater that mixes with groundwater in an excavation is also subject to the controls in
the general permit for Construction Dewatering.
No materials shall be discharged in quantities that will have an adverse effect on the receiving
waters. The measures listed below will be implemented to achieve these objectives.
x Proper and lawful disposal of all waste materials.
x Control any spills and leaks that may occur and clean up (mitigate).
x Use of designated areas for equipment repair and cleaning.
x Careful application of irrigation water.
The State Stormwater discharge permit authorizes the conditional discharge of construction
dewatering to the ground, as long as the discharge flows stay on-site within the permit boundaries).
For any construction dewatering of groundwater not authorized under a separate CDPS discharge
permit, the Erosion and Sediment Control Plan shall clearly describe and locate the practices to be
used.

4.0 SPILL PREVENTION AND CONTINGENCY PLAN
4.1 PURPOSE OF THE SPILL PREVENTION PLAN
This section describes measures to prevent, control, and minimize impacts from a spill of chemical
products (hazardous, toxic, or petroleum substances) during construction. This plan identifies the
handling, transportation, storage, and disposal procedures for these chemical products and outlines
response procedures to be followed in the event of a spill. This plan provides a contact list and
reporting procedures for governing agencies.
4.2 HAZARDS ASSESSMENT
Activities on the site that may have an impact on stormwater include the following:
• Vehicle fuels and fluids • Equipment and/or vehicle washing
• Fertilizers, chemicals, or other material storage • Waste storage or disposal
• Off-site and roadway vehicle tracking • Loading/unloading areas
• Concrete truck washout • Chemical toilets and human waste
• Unknown or unmarked materials
These hazards are discussed below:
Vehicle Fuels and Fluids:
The materials and fluids found in and emitted from motor vehicle operation are hazardous to humans
and wildlife. Spills of diesel fuel, gasoline, hydraulic fluid, brake fluid, engine oil, lubricants, grease, etc.,
no matter the amount, are considered serious and emergency response procedures must be initiated to
clean up the spill. These materials are toxic in liquid or vapor form and can be flammable and
combustible, so proper procedures must be followed to clean up spills. Antifreeze, Freon, and other
non-petroleum products are equally harmful and the same spill prevention and handling methods shall be
followed.
Potential sources include all construction equipment, trucks, mobile refueling trucks, and personal
vehicles. Potential causes include emergency ruptures in tanks or equipment, overflow during
refueling/replenishing fluids, seepage or ruptures from hydraulic lines, oil spills and leakage, vehicle
servicing, vehicular accidents, and natural disasters.
Erosion and Sediment Control Plan for Affinity Fort Collins
Page 19
Equipment and/or Vehicle Washing:
Equipment washing on-site can generate sediment and pollutant-laden water. The materials and fluids
from motor vehicles can be freed during washing activities and can be present in seemingly clean wash
water. Potential sources include all construction equipment, trucks, mobile refueling trucks, and
personal vehicles. Pollutants can be generated from washing as well as from rain/snowfall and snowmelt.
Fertilizers, Chemicals, or Other Material Storage:
Stored fertilizers, chemical additives, acids, cement, grout, etc. are hazardous substances that require
designated and special storage areas on-site. Any untreated runoff from these areas can contain these
substances and spills can be detrimental to wildlife if not cleaned up.
Waste Storage or Disposal:
Solid waste storage and disposal is expected to occur on-site. Stormwater and snowmelt runoff that has
come in contact with solid waste can convey hazardous pollutants into receiving waters. Potential
sources include concrete, concrete formwork, treated and untreated lumber, scrap metal, electrical
equipment, etc.
Off-site and Roadway Vehicle Tracking:
Vehicle tracking on roadways, both on-site and offsite, creates sediment-laden storm runoff that has the
capacity to clog stormwater infrastructure and reduce the effectiveness of water quality and detention
features. Sources include construction vehicles, personal vehicles, and construction personnel. All dirt,
mud, sand, and sediment brought onto roads by vehicles or otherwise should be treated as a pollutant.
Loading/Unloading Areas:
Loading and unloading areas are sources for fluid and dry material spills, leaks from motor vehicles, and
dust.
Concrete Truck Washout:
Concrete washouts are sources for alkaline wastewater. The washwater and wasted concrete present
at washout locations creates hazardous and corrosive waste that can be lethal to terrestrial and aquatic
wildlife.
Chemical Toilets and Human Waste:
Human waste and the chemical additives to portable toilets are biologically hazardous substances that
affect humans and wildlife. Any spill or leakage, no matter the amount, are considered serious and
emergency response procedures must be initiated to clean up the spill. Proper disposal and disinfection
of all waste is required.
Unknown or Unmarked Materials:
The potential exists for encountering unknown or illegally buried substances and materials. These may
be in the form of storage tanks, utility lines, unmarked drums, septic system components, etc.
Personnel shall be alert to indicators of unknown hazardous wastes and materials, including
encountering resistance with equipment during excavation, noticing unusual odors during excavation, or
Erosion and Sediment Control Plan for Affinity Fort Collins
Page 20
hearing contact with foreign materials during excavation. The hazard associated with unearthing
unknown buried materials shall be assumed high until determined otherwise. Any and all unknown
hazardous materials require special handling and emergency response procedures.
Spill Prevention and Containment:
Properly managing these materials onsite will greatly reduce the potential for stormwater pollution.
Good housekeeping along with proper use and storage of these construction materials form the basis
for proper management of chemical products.
The proper use of materials and equipment along with the use of general common sense greatly reduce
the potential for contaminating stormwater runoff. The following is a list of good housekeeping practices
to be used during the construction project:
x Storage of hazardous materials, chemicals, fuels, and oils and fueling of construction equipment
will not be performed within 150 feet of a definitive stormwater drainage.
x An effort will be made to store only enough product required to do the job.
x Materials will be stored in a neat, orderly manner, in appropriate closed containers, in secondary
containment and, if possible, under a roof or other enclosure.
x Products will be kept in their original containers with the original manufacturer’s label.
x Substances will not be mixed with one another unless recommended by the manufacturer.
x Whenever possible, all of the product will be used up before disposing of the container.
x Manufacturer’s recommendations for proper use of a product will be followed.
x If surplus product must be disposed of, local and state recommended methods for proper
disposal will be followed.
Vehicle Fuels and Fluids:
All personnel shall be trained to maintain and inspect their vehicles and equipment, and any vehicle
found to be the source or a potential source of a spill shall be promptly removed from the construction
site and repaired, with care taken to ensure further spills do not occur on the way. Vehicles with
continual leaks shall be removed from the site until fully restored. No vehicular leaking of any kind will
be permitted on the job site. Contractors are solely responsible for any and all spills of hazardous
materials and any subsequent cleanup, disposal, restoration and remediation.
Restrictions for vehicle refueling, servicing, and maintenance operations shall be followed at all times.
Storage of hazardous materials, chemicals, fuels, and oils and fueling of construction equipment will not
be performed within 150 feet of a definitive stormwater drainage. No refueling or servicing shall take
place without drip pans and absorbent material properly placed to collect leaks and spills. Any materials
required for vehicle operations and maintenance shall be stored upright in a sealed, marked, approved
storage container (the original container if possible) away from construction activities.
Any leaked fluids or collected soil containing leaked fluids shall be sealed in leak-proof containers and
taken to an appropriate site for disposal or recycling. These materials and soils shall be designated as
Erosion and Sediment Control Plan for Affinity Fort Collins
Page 21
hazardous waste and disposed of accordingly. Under no circumstances shall contaminated soils be
added to a spoils pile, disposed of at a regular disposal site, buried on-site, or otherwise treated as non-
hazardous waste.
Flammable or Combustible Materials:
All products will be stored in tightly sealed containers that are clearly labeled. The containers will be
stored in secondary containment, which will be of sufficient size to contain the entire contents of the
primary container plus a sufficient quantity for precipitation (a total of approximately 110 percent of the
volume of the primary container). The secondary containment will be an impermeable containment
basin to prevent any spills or leaks from reaching the ground. The containment may be one of the
following or other means that meets the definition of impermeable: 1) a temporary earthen berm lined
with 20-ml plastic, 2) a portable tank or basin, or 3) a galvanized steel trough.
After each rain event, the contractor will inspect the contents of all secondary containment areas. If
there is no visible sheen on the collected water, it can be pumped or drained to the ground in a manner
that does not cause scouring. If a sheen is present, it must be cleaned up using absorbent materials prior
to discharging or disposing of the water. The absorbent material will be disposed of properly.
Unknown or Unmarked Materials:
Awareness of the potential for encountering unknown hazards and early recognition of potentially
hazardous materials are the best prevention for avoiding emergency spills and cleanup. Personnel shall
visually inspect excavation operations to identify any evidence of hazardous waste appearing in the soil.
Indicators include vent pipes, concrete pads, portions of drums or tanks, discolorations or stains in the
soil, and unusual or noxious odors. Personnel shall investigate the source of the indicators before
resuming activities. Any underground pipelines or tanks shall be treated with the potential to rupture,
release toxic fumes or fluid, or combust or explode. Any excavation shall be considered a confined
space when unknown materials are encountered.
The contractor is responsible for coordination with Larmier County for hazardous material disposal and
for coordination with any sanitation service or directly with any landfill for non-hazardous material
disposal.
4.3 EMERGENCY RESPONSE PROCEDURES
The contractor shall keep and maintain adequate supplies of spill containment equipment on-site.
These materials shall include specialized spill containment and cleanup kits, discussed below, and
excess erosion control measures and vacuum pumps.
Erosion and Sediment Control Plan for Affinity Fort Collins
Page 22
At a minimum, the following kit shall be kept on-site at all times, with each construction crew, in
the event a spill does occur:
x 1-55 gallon Drum
x 1 shovel
x 1 broom
x 1 pair nitrile gloves
x 1 pair safety goggles
x 4 sorbent socks
x 2 sorbent booms
x 1 bag sorbent granular material or peat moss

book shall be provided.
Personnel on the site will be made aware of cleanup procedures and the location of spill cleanup
equipment. Materials and equipment needed for cleanup procedures will always be kept readily
available on the site, either at an equipment storage area or on contractor’s trucks.
In addition to the material management practices discussed previously, the following spill control
and cleanup practices will be followed to prevent stormwater pollution in the event of a spill:
x Secure the site by turning off machinery, disable hoses and pumping, and keep personnel and
traffic away from the spill. The site shall not be left unattended.
x The initial spill reporting shall be completed by the spill observer. This will determine the type
of spill and the volume and extent of the spill. The spill report form is included in Appendix D.
x A rough estimate of the volume of the spill is needed initially to determine the equipment,
personnel, and disposal needs.
x Minor spills have the lowest potential for environmental damage, not necessarily the lowest
volume.
x Spills will be contained and cleaned up immediately after discovery.
x Manufacturer’s methods for spill cleanup of a material will be followed as described on the
material’s MSDS.
x Drums and bags containing used clean up materials will be labeled with the contents and date
and shall be marked as 'hazardous'.
x The contractor will be responsible for all cleanup activities in accordance with applicable local,
state, and federal regulations.
x The first individual(s) to notice the spill shall be responsible for its reporting. All responders to
the spill must have completed training in spill recognition and hazardous material response. The
personnel to be notified and who will assist in the hazardous spill response shall include, at a
minimum, the spill observer(s) and the contractor superintendent.

5.0 INSPECTIONS AND MAINTENANCE
5.1 INSPECTION AND MAINTENANCE OVERVIEW
A site inspection of all erosion control facilities shall be conducted at least once every two weeks
and immediately following any significant precipitation or snowmelt event that could cause surface
erosion and every 30 days for inactive construction projects. The inspection must determine if
there is evidence of, or the potential for, pollutants entering the drainage system, and BMPs should
be reviewed to determine if they still meet the design and operational criteria in the Erosion and
Sediment Control Plan and that they continue to adequately control pollutants at the site. The
construction site perimeter, disturbed areas, discharge points and areas used for material storage
that are exposed to precipitation shall be inspected for evidence of, or the potential for, pollutants
entering the storm drainage system. Erosion and sediment control measures identified in this
Erosion and Sediment Control Plan and on the construction plans shall be observed to ensure that
they are operating correctly. Any other structural BMPs that may require maintenance, such as
secondary containment around fuel tanks or the conditions of spill response kits, shall also be
inspected. Stormwater items to be inspected include the following:
x Condition & failures of structural & non-structural BMPSs
x Evidence of spills, upsets & discharges
x Maintaining accurate Erosion and Sediment Control Plan documentation
x Material Handling and storage
x Good Housekeeping
x Site Stabilization

Upon acceptance of final stabilization measures, all temporary BMPs shall be removed and proper
function of inlets, drainageways, or other storm water conveyance elements shall be restored.
The General Contractor shall be responsible for maintaining the storm water controls in good
working order including removal measures until the Inactivation Notice is filed with the State, a
copy of the Inactivation Notice is included in Appendix B. The state requires the Inactivation
Notice be filed within 3 months of the proposed end of construction. Alternatively, permit
responsibilities may be transferred or reassigned by submitting a Notice of Transfer and Acceptance
of Terms or a Reassignment of Coverage if control of a portion of the site changes parties. The
City of Fort Collins Utilities Department staff shall document and approve changes regarding
inspection frequency and closing of the CDPS permit.

6.0 NON-STORMWATER DISCHARGES
6.1 MANAGEMENT ANDREPORTING OF HAZARDOUS RELEASES
All potential pollutants used during construction will be handled and disposed of in a manner that
does not contaminate storm water. All materials used during construction which have the potential
to impact storm water quality will be stored, managed, used and disposed of in a manner that
minimizes the potential for releases to the environment, especially storm water.
Hazardous spills and releases shall be managed and reported in accordance with the provisions of
Section 4.0 of this report, and in conformance with all local, state, and federal requirements.
6.2 PROJECT MANAGEMENT
The contractor is responsible for all spill containment and cleanup, initiating notification and
response procedures, and all spill recognition and response training. Implementation and
management of the environmental aspects of this project under this ESC are the responsibilities of
the General Contractor. The General Contractor shall ensure the all contractors providing
services on the project have access to a copy of the ESC and appropriate training regarding storm
water pollution prevention. The General Contractor, Building Contractor, Utility Installations

Erosion and Sediment Control Plan for Affinity Fort Collins
Page 32
7.0 CONCLUSION
This Erosion and Sediment Control Plan has been prepared in accordance with the criteria and
methods described in the “State of Colorado General Permit Application and Stormwater
Management Plan Guidance for Stormwater Discharges Associated with Construction Activity.”
The erosion control features and best management practices have been designed to comply with
City of Fort Collins standards and specifications. All temporary and permanent erosion and
sediment control BMPs shall be inspected, maintained and repaired by the General Contractor as
needed to ensure continued performance of their intended function.
The General Contractor shall remove all temporary erosion and sediment control BMPs after
stabilization is achieved or after temporary BMPs are no longer needed. Trapped sediment will be
removed by the General Contractor or stabilized onsite. Disturbed soil areas resulting from
removal of BMPs or the General Contractor will permanently stabilize vegetation as soon as
possible.
Final stabilization shall be considered complete when all facilities are fully constructed and the
vegetative cover has been established with a density of at least 70 percent of pre-disturbance levels.
The contractor will be required to maintain the remaining BMPs for a period of one year.
The anticipated cost for installation, maintenance, and removal of the required temporary soil
erosion and sediment control measures, including dewatering and seeding and mulching, is
$30,507.40, as shown below.

Single Family Residential Development
Other—Description:
(i.e., total, including all phases, filings, lots, and infrastructure not covered by this application)
Provide both the total area of the construction site, and the area that will undergo disturbance, in acres. Note: aside from clearing, grading and excavation
activities, disturbed areas also include areas receiving overburden (e.g., stockpiles), demolition areas, and areas with heavy equipment/vehicle traffic and storage
that disturb existing vegetative cover (see construction activity description under the APPLICABILITY section on page 1). If the project is part of a larger common
plan of development or sale (see the definition under the APPLICABILITY section on page 1), the disturbed area of the total plan must also be included.

G) ANTICIPATED CONSTRUCTION SCHEDULE
Construction Start Date: Final Stabilization Date:
Construction Start Date - This is the day you expect to begin ground disturbing activities, including grubbing, stockpiling, excavating, demolition,
and grading activities.
Final Stabilization Date - in terms of permit coverage, this is when the site is finally stabilized. This means that all ground surface disturbing
activities at the site have been completed, and all disturbed areas have been either built on, paved, or a uniform vegetative cover has been
established with an individual plant density of at least 70 percent of pre-disturbance levels. Permit coverage must be maintained until the site is
finally stabilized. Even if you are only doing one part of the project, the estimated final stabilization date must be for the overall project.
If permit coverage is still required once your part is completed, the permit certification may be transferred or reassigned to a new responsible
entity(s).
H) RECEIVING WATERS (If discharge is to a ditch or storm sewer, include the name of the ultimate receiving waters)
Immediate Receiving Water(s):
Ultimate Receiving Water(s):
Identify the receiving water of the stormwater from your site. Receiving waters are any waters of the State of Colorado. This includes all water courses, even if they
are usually dry. If stormwater from the construction site enters a ditch or storm sewer system, identify that system and indicate the ultimate receiving water for the
ditch or storm sewer. Note: a stormwater discharge permit does not allow a discharge into a ditch or storm sewer system without the approval of the owner/
operator of that system.

WATER RIGHTS
The State Engineers Office (SEO) has indicated that any discharge that does not return water directly to
surface waters (i.e. land application, rapid infiltration basins, etc.) has the potential for material injury to a
water right. As a result, the SEO needs to determine that material injury to a water right will not occur from
such activities. To make this judgment, the SEO requests that a copy of all documentation demonstrating
that the requirements of Colorado water law have been met, be submitted to their office for review. The
submittal should be made as soon as possible to the following address:
Colorado Division of Water Resources ● 1313 Sherman Street, Room 818 ● Denver, Colorado 80203

Should there be any questions on the issue of water rights; the SEO can be contacted at (303) 866-3581. It is
important to understand that any CDPS permit issued by the division does not constitute a water right.
Issuance of a CDPS permit does not negate the need to also have the necessary water rights in place. It is
also important to understand that even if the activity has an existing CDPS permit, there is no guarantee that
the proper water rights are in place.

WATER RIGHTS
The State Engineers Office (SEO) has indicated that any discharge that does not return water directly to surface waters (i.e.
land application, rapid infiltration basins, etc.) has the potential for material injury to a water right. As a result, the SEO
needs
to determine that material injury to a water right will not occur from such activities. To make this judgment, the SEO requests
that a copy of all documentation demonstrating that the requirements of Colorado water law have been met, be submitted to
their office for review. The submittal should be made as soon as possible to the following address:
Colorado Division of Water Resources
1313 Sherman Street, Room 818
Denver, Colorado 80203
Should there be any questions on the issue of water rights, the SEO can be contacted at (303) 866-3581. It is important to
understand that any CDPS permit issued by the Division does not constitute a water right. Issuance of a CDPS permit does not
negate the need to also have the necessary water rights in place. It is also important to understand that even if the activity has
an existing CDPS permit, there is no guarantee that the proper water rights are in place.

Management
a) The SWMP shall clearly describe the practices used to achieve final stabilization of all disturbed areas at the site, and
any planned practices to control pollutants in stormwater discharges that will occur after construction operations
have been completed at the site.
b) Final stabilization practices for obtaining a vegetative cover should include, as appropriate: seed mix selection and
application methods; soil preparation and amendments; soil stabilization practices (e.g., crimped straw, hydro mulch
or rolled erosion control products); and appropriate sediment control BMPs as needed until final stabilization is
achieved; etc.
c) Final stabilization is reached when all ground surface disturbing activities at the site have been completed, and
uniform vegetative cover has been established with an individual plant density of at least 70 percent of pre-
disturbance levels, or equivalent permanent, physical erosion reduction methods have been employed.
The Division may, after consultation with the permittee and upon good cause, amend the final stabilization criteria in this
section for specific operations.

Reporting Environmental Releases in Colorado January 2009
Colorado Environmental Release Reporting
Additional reporting requirements
may be found in permits, licenses,
registrations, contingency and
pollution prevention plans, fire
codes, and local ordinances.
When a release of a hazardous material or other substance occurs to the environment, there are a
number of reporting and notification requirements that must be followed by the company or
individual responsible for the release. Environmental releases must be reported to the appropriate
authorities so that necessary response actions are taken in a timely fashion to ensure maximum
protection of human health and the environment.
However, taking appropriate and timely response actions
do not relieve you of your responsibility to report a release.
In addition, the responsible party is always liable for any
damages that may result from a release, and is responsible
for appropriate clean up actions whether or not the release
is required to be reported.
There is no penalty for over-reporting, but there are for failing to report a release. If you are unsure
if a release needs to be reported, the Colorado Department of Public Health and Environment (the
Department) recommends that releases be reported immediately even if the quantity of the release
has not yet been determined. Your follow-up report will provide details that explain why the
release was or was not reportable.
“Release” includes any spilling, leaking, pumping, pouring, emitting, emptying, discharging,
injecting, escaping, leaching, dumping, or disposing into the environment, including abandonment
or discarding of barrels, containers, and other closed receptacles containing any hazardous
substance, pollutant, or contaminant.
Most spills and releases are
covered by more than one
reporting requirement, and all
requirements must be met.
"Environment" is generally defined as any surface water, ground water, drinking water supply, land
surface, subsurface strata, or ambient air. Releases into containment devices and those completely
contained within a building or other structure are not releases into the environment as long as the
hazardous substance does not volatilize into the ambient air or
otherwise have the potential to enter the environment (e.g.,
through the floor or cracks in the floor). Releases of a substance
into a storm drain or sewer, or onto a parking lot or roadway, are
considered to be releases to the environment.
Release reporting requirements are based on the type of material released and/or the situation under
which the release occurred. Additional reporting requirements may be found in permits, licenses,
registrations, contingency and pollution prevention plans, fire codes, and local ordinances. Please
check all of the possible requirements for reporting. Most spills and releases are covered by more
than one reporting requirement, and ALL requirements must be met. Enforcement action may be
taken against those who fail to provide required notifications or reports.
A. Comprehensive Environmental Response, Compensation and Liability Act
(CERCLA)
The Comprehensive Environmental Response, Compensation and Liability Act, commonly known
as Superfund or CERCLA, provided broad Federal authority to respond directly to releases or
threatened releases of hazardous substances that may endanger public health or the environment.
This Act also enabled revision of the National Contingency Plan, which provides the guidelines and
1
Reporting Environmental Releases in Colorado January 2009
procedures needed to respond to releases and threatened releases of hazardous substances,
pollutants, or contaminants.
Under CERCLA, the US EPA was directed to establish reporting quantities for all hazardous
substances. The term "hazardous substance" is defined in CERCLA Section 101(14). These are
defined by reference to substances that are listed or designated under other environmental statutes.
They include:
all hazardous air pollutants (HAPs) listed under Section 112(b) of the Clean Air Act (CAA).
Radio-nuclides are hazardous substances because EPA designated them generically as
hazardous air pollutants under Section 112(b) of the Clean Air Act. Even though the source
of their listing is the Clean Air Act, releases of radionuclides to all media, not just to air, are
covered by CERCLA's reporting requirements.
toxic pollutants that are subject to pretreatment standards under Section 307(a) of the Clean
Water Act (CWA) and toxic pollutants that present an imminent danger to public health
when discharged to waters of the United States as designated under Section 311(b)(2)(A) of
the Clean Water Act. All Clean Water Act hazardous substances are CERCLA hazardous
substances, but only some CERCLA hazardous substances are Clean Water Act hazardous
substances.
wastes that are regulated as listed and/or characteristic
hazardous wastes under the Resource Conservation and
Recovery Act (RCRA). This includes thousands of
hazardous wastes that are not specifically listed but that
exhibit one or more of the characteristics of ignitability,
reactivity, corrosivity or toxicity. A material is
considered to be a release of a CERCLA hazardous
substance if the material was a waste prior to release, or if
the substance is not cleaned up for reuse and thus must be
disposed of as a RCRA hazardous waste after release.
Report releases at or above
the reportable quantity (RQ)
within 24 hours:
Hazardous air pollutants
under Section 112(b) of
Clean Air Act
Toxic pollutants under
Section 307(a) or under
Section 311(b)(2)(A) of
Clean Water Act
RCRA hazardous wastes
Elements, compounds or
substances under Section
102 of CERCLA
any element, compound, mixture solution or substance
designated under Section 102 of CERCLA that may
present substantial danger to public health or welfare or
the environment.
any imminently hazardous chemical substance or mixture that EPA has taken action against
under Section 7 of the Toxic Substances Control Act (TSCA). Any hazardous chemical
substance or mixture that EPA has taken action against under this Act would automatically
become a hazardous substance. To date, EPA hasn't designated any hazardous substances
under the Toxic Substances Control Act.
The person in charge of a facility or vessel must immediately report a release to the National
Response Center (NRC) as soon as they have knowledge of a release to the environment of a
CERCLA hazardous substance at or above the reportable quantity assigned to that substance within
a 24-hour period. If the release is a mixture or solution of hazardous substances, it must be reported
if the reportable quantity for any hazardous constituents is met or exceeded. If the responsible party
doesn't know the quantity of one or more of the hazardous constituents contained in a mixture or
solution, they must report the release if the total amount of the mixture or solution released equals
or exceeds the reportable quantity for the hazardous constituent with the lowest reportable quantity.
Reporting is also required if a non-CERCLA substance is released into the environment and rapidly
Reporting Environmental Releases in Colorado January 2009
These notification and reporting requirements are included in 40 CFR Part 302. A list of CERCLA
hazardous substances is included in Table 302.4 of these regulations.
B. Emergency Planning and Community Right-to-Know Act (EPCRA)
The Superfund Amendments and Reauthorization Act of 1986 reauthorized the Comprehensive
Response, Compensation and Liability Act to continue cleanup activities around the country.
Several amendments, definitions, clarifications and technical requirements were added to the
legislation, including additional enforcement authorities. Title III of the Superfund Amendments
also authorized the Emergency Planning and Community Right-to-Know Act (EPCRA), which
established the community's right to information about the chemicals that are stored, used at and/or
released from local facilities. It also established a framework for developing emergency plans for
responding to releases and reporting requirements for facilities.
A list of EPCRA threshold
planning quantities (TPQ) is
included in 40 CFR Part
355 Appendices A & B.
Under this Act, owners or operators of facilities at which a
hazardous substance or extremely hazardous substance is produced,
used or stored must provide immediate notification to the National
Response Center (NRC), the State Emergency Response
Commission (SERC) and the affected Local Emergency Planning
Committee (LEPC) when there is a release of a hazardous substance or extremely hazardous
substance with the potential to affect off-site persons that equals or exceeds its reportable quantity
within a 24-hour period. If the release is an EPCRA extremely hazardous substance, but not a
CERCLA hazardous substance, then only the SERC and LEPC need to be notified. Note – there
may be more than one SERC and/or LEPC potentially affected by a release. Don’t wait until there
is a release to contact the SERC and LEPC(s) to ensure that the correct contacts will be made in the
event of a spill. For a list of LEPCs, contact the Colorado Department of Local Affairs.
The owner or operator of the facility must report a release as soon as they know about it. In
addition to immediate telephone notification, the responsible party must also send a follow-up
written report as soon as practicable after the release to both the State Emergency Response
Commission (in this case, to the Colorado Department of Public Health and Environment) and the
Local Emergency Planning Committee. This report must describe the release, associated response
actions taken, and any known or anticipated health risks associated with the release.
A table of CERCLA reportable quantities
(RQ) is includedin40CFR Section 302.4.
Although EPCRA requires notification only for
releases that have the potential to affect persons beyond
the facility boundary, EPA and the Colorado
Department of Public Health and Environment strongly encourage facilities to report onsite releases
if there is ANY potential for the release to migrate offsite. The burden of proof is on the facility to
show that any release into the environment of a reportable quantity or more of a hazardous
substance or extremely hazardous substance has NO POTENTIAL for offsite migration (e.g., via
groundwater, the wind or getting tracked offsite by workers and vehicles).
The State Emergency Response Commission (SERC) in Colorado is called the Colorado
Emergency Planning Commission (CEPC). It consists of representatives of the Colorado
Department of Public Health and Environment – Hazardous Materials and Waste Management
Division, the Colorado Department of Local Affairs – Colorado Division of Emergency
Management and the Division of Local Government, the Colorado Department of Public Safety –
3
Reporting Environmental Releases in Colorado January 2009
Fire Safety Division, and the Colorado State Patrol. The Commission also includes representatives
of affected industries, local governments, public interest or community groups and the Local
Emergency Planning Committee (LEPC) community. The Colorado Department of Public Health
and Environment represents the Commission for reporting purposes.
Reportable Quantities Under CERCLA and EPCRA
All reportable quantities are listed in pounds (except radionuclides, which are in curies). Congress
established a one pound reportable quantity for all hazardous substances and extremely hazardous
substances until EPA could evaluate each substance and adjust the reportable quantity to a level
more appropriate for the substance. During this assessment, each hazardous substance was
evaluated for six primary criteria: aquatic toxicity, mammalian toxicity, ignitability, reactivity,
chronic toxicity, and potential carcinogenicity. Reportable quantities for CERCLA hazardous
substances are listed in 40 CFR Section 302.4.
EPCRA extremely hazardous substances that are also hazardous substances under CERCLA have
the same reportable quantity that is applicable under CERCLA. If not also listed as a CERCLA
hazardous substance, extremely hazardous substances have a reportable quantity equal to the
EPCRA threshold planning quantity (TPQ) for that substance. The threshold planning quantity is
the quantity designated for each chemical in 40 CFR Part 355 Appendices A and B that triggers
notification by facilities to the State Emergency Response Commission that those facilities are
subject to emergency planning requirements.
For convenience, reportable quantities for hazardous substances and extremely hazardous
substances can also be found in the EPA List of Lists (EPA 550-B-01-003). Bear in mind that
because this document is only updated periodically, it may not contain recently added substances.
EPCRA extremely hazardous substances that
are also CERCLA hazardous substances have
the same RQ as under CERCLA.
EPCRA extremely hazardous substances that
are not listed under CERCLA have an RQ
equal to their TPQ under EPCRA.
All concurrent releases of the same substance from a single facility must be combined to determine
if a reportable quantity has been met or exceeded. Releases of different substances from a single
facility should not be combined for purposes of determining if the releases need to be reported.
Rather, each substance should be evaluated separately to determine if one or more reportable
quantities have been met or exceeded. For example, spilling a mixture containing half the
reportable quantity of one hazardous substance and
half the reportable quantity of another hazardous
substance does not trigger the reporting
requirement. Releases from separate facilities
should be treated as separate releases and should
not be combined to determine if a reportable
quantity has been met or exceeded.
Mixtures
Most hazardous substances and extremely hazardous substances are not used or stored in pure form,
but are mixtures or solutions. If a mixture of hazardous substances or extremely hazardous
substances is released and the concentration of all hazardous substances and extremely hazardous
substances in the mixture is known, then you must calculate the amount of each hazardous
substance and extremely hazardous substance that has been released. If there is more than one
hazardous substance or extremely hazardous substance in a mixture, you must check the reportable
quantity for each substance. The release must be reported if the reportable quantity for any
4
Reporting Environmental Releases in Colorado January 2009
hazardous substance or extremely hazardous substance has been met or exceeded. If the
concentrations of the hazardous substances or extremely hazardous substances in the mixture are
not known, then the release must be reported when the total amount of the mixture released equals
or exceeds the reportable quantity for the constituent with the lowest reportable quantity.
Radionuclides
Releases of radionuclides in a mixture are additive. These releases are subject to reporting:
if each radionuclide in a released mixture or solution is known, then the ratio between the
quantity released and the reportable quantity for the radionuclide must be determined for
each radionuclide. If the sum of the ratios for the radionuclides in the mixture or solution
released is equal to or greater than one, it must be reported.
if all of the radionuclides in the mixture are known but the quantity released of one or more
of the radionuclides is unknown, it must be reported if the total quantity released is equal to
or greater than the lowest reportable quantity of any one radionuclide in the mixture.
if one or more radionuclides in the mixture is unknown, it must be reported if the total
quantity released is equal to or greater than either one curie or the lowest reportable quantity
of any of the known radionuclides in the mixture (whichever is lower).
Exceptions and Exclusions
Petroleum Products
A release of a petroleum product
containing a reportable quantity of
an EPCRA extremely hazardous
substance is reportable.
Under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA),
petroleum products are excluded from the definition of hazardous substance. "Petroleum product"
includes crude oil, any fraction of crude oil that is not specifically listed as a hazardous substance,
natural and synthetic gases, and mixtures of natural and synthetic gases. EPA interprets petroleum
as including those amounts of hazardous substances, like
benzene, that are indigenous to crude oil or its fractions or
that are normally added during the refining process.
Hazardous substances added to the petroleum or increased
in concentration solely as a result of contamination during
use are not included in the petroleum exclusion.
Unlike the petroleum exclusion under CERCLA, extremely hazardous substances that are naturally
occurring in petroleum products or that are normally added during refining are subject to reporting
under the Emergency Planning and Community Right-to-Know Act (EPCRA). Therefore, a release
of a petroleum product containing a reportable quantity of one or more extremely hazardous
substances is reportable to the Colorado Emergency Planning Commission (CERC) and the Local
Emergency Planning Committee (LEPC) if a reportable quantity is met or exceeded.
Note: releases of oil and petroleum to water are also covered
under the Clean Water Act (Section E of this document).
Releases of petroleum from regulated storage tanks are covered
under the Colorado storage tank regulations (Section H of this
document).
The responsible party is always
responsible for appropriate clean
up actions whether or not the
release is required to be reported.

Reporting Environmental Releases in Colorado January 2009
Metals
Under normal handling and use, solid forms of most metals present few health hazards. Metal fines
and metal dust may cause irritation of the eyes, skin, and respiratory system, and fine particles of
certain metals, including antimony, arsenic, beryllium, cadmium, chromium, copper, lead, nickel,
selenium, silver, thallium, or zinc, dispersed in the air can be an explosion and/or health hazard.
EPA has determined that releases of these metals with particles larger than 100 micrometers would
not normally require response action due to the unlikely inhalation of such large particles.
However, notification of the release of a reportable quantity of antimony, arsenic, beryllium,
cadmium, chromium, copper, lead, nickel, selenium, silver, thallium, or zinc is required if the mean
diameter of the particles released is less than 100 micrometers (0.004 inches). An exception to this
is a release of a metal classified as a radionuclide, which does not qualify for this exemption even if
the particles meet the size criteria.
Naturally Occurring Radionuclides
Notification of the release of naturally occurring radionuclides from large land holdings, like parks
or golf courses, is not required. EPA broadened this exemption to include land containing ore
reserves even if the undisturbed ores contain elevated natural concentrations of radionuclides, and
to land disturbance activities including farming, construction, and disturbance incidental to
extraction activities at all mines except uranium, phosphate, tin, zircon, hafnium, vanadium,
monazite, and rare earth mines. Land disturbance incidental to extraction activities includes land
clearing, overburden removal and stockpiling, and excavating, handling, transporting and storing
ores and other raw materials. Land disturbance incidental to extraction also includes replacing
materials in mined-out areas as long as those materials have not been processed and don't contain
elevated radionuclide concentrations. Notification of the release of naturally occurring
radionuclides from sites where coal and coal ash (fly ash, bottom ash, boiler slag) are stored or
disposed is also not required.
Federally Permitted Releases
Releases that are regulated under one or more of the following programs are exempt from CERCLA
and EPCRA reporting requirements:
permitted discharges under the National Pollutant Discharge Elimination System (NPDES);
permitted dredge and fill discharges under Section 404 of the Clean Water Act;
permitted and interim status hazardous waste units under the Resource Conservation and
Recovery Act;
permitted discharges under the Marine Protection, Research and Sanctuaries Act;
permitted injection of fluids under the Underground Injection Control (UIC) program in
accordance with the Safe Drinking Water Act;
air emissions subject to permit or control regulations under the Clean Air Act;
permitted or allowed injection of fluids to develop crude oil or natural gas supplies;
discharges of contaminants to Publicly Owned Treatment Works (POTW) if in compliance
with pretreatment requirements under the Clean Water Act;
releases of certain nuclear materials if in compliance with a license, permit, regulation or
order issued in accordance with the Atomic Energy Act.
Registered Pesticides
The normal application of a pesticide product registered under the Federal Insecticide, Fungicide
and Rodenticide Act (FIFRA) is exempt from CERCLA and EPCRA reporting. This exemption
includes the handling and storage of the product by an agricultural producer, but does not include
6
Reporting Environmental Releases in Colorado January 2009
any spills of the pesticide. Pesticide spills are reportable if the amount spilled meets or exceeds the
reportable quantity.
Continuous Releases
A continuous release is a release that occurs without interruption or abatement or that is routine,
anticipated, intermittent, and incidental to normal operations or treatment processes. When a
release of this type occurs, officials do not have to be notified each time. Instead, the facility can
report it as a continuous release to the National Response Center, the Colorado Emergency Planning
Commission and the Local Emergency Planning Committee(s) by telephone. This should be
followed by a written report submitted to EPA Region 8, the Colorado Department of Public Health
and Environment and the Local Emergency Planning Committee within 30 days of the initial
telephone call. The written report should provide information about the source, composition, and
normal range of the release. Periodic follow-up reports may also be required. Any release that
exceeds the normal range (called a “statistically significant increase”) must be reported immediately
to the National Response Center, the Colorado Department of Public Health and Environment and
the Local Emergency Planning Committee as if they were new release events. The normal range is
determined by the amount of a hazardous substance released over any 24-hour period under normal
operating conditions during the preceding year. Only releases that are both continuous and stable in
quantity and rate can be included in the normal range.
Continuous release of an extremely hazardous substance that is not a CERCLA hazardous substance
need only be reported to the Colorado Department of Public Health and Environment and the Local
Emergency Planning Committee. A written report should also be sent to these two agencies within
30 days and any statistically significant increases in the release should be reported to both agencies.
Periodic follow-up reports may also be required.
C. Resource Conservation and Recovery Act (RCRA)
All Resource Conservation and Recovery Act (RCRA) listed and characteristic hazardous wastes
are designated as hazardous substances under the Comprehensive Environmental Response,
Compensation and Liability Act (CERCLA). For more information on listed and characteristic
hazardous wastes, please review the Hazardous Waste Identification Guidance Document from the
Hazardous Materials and Waste Management Division (http://www.cdphe.state.co.us/hm/hwid.pfd).
The reportable quantity for F- and K-listed hazardous wastes is based on the hazardous waste code.
If the composition and concentrations of all included constituents is not known, the reportable
quantity would be as listed for the waste code in 40 CFR Section 302.4. If the waste is analyzed
and the concentrations of ALL of its hazardous constituents are identified, then reportable quantities
of the specific constituents can be used to determine when reporting is required. For example, if a
release of an F005 listed hazardous waste occurred and the concentrations of the constituents
making up the waste were unknown, the reportable quantity would be 100 pounds. If it were known
that the F005 waste was comprised of 50% toluene (reportable quantity 1000 pounds) and 50%
methyl ethyl ketone (reportable quantity 5000 pounds), then the release would be reported when
2000 pounds of the mixture were released. [Since the reportable quantity for toluene is less than
that for methyl ethyl ketone, the amount of toluene released will determine when the release must
be reported. Since the mixture is 50% toluene, it would take 2000 pounds of the mixture to meet
the reportable quantity of 1000 pounds for toluene.]
7
Reporting Environmental Releases in Colorado January 2009
P- and U-listed hazardous wastes are reported based on the reportable quantity for the hazardous
substance that the waste is listed for. For example, the reportable quantity for hazardous waste code
U122 (formaldehyde) is 100 pounds. For the purposes of release reporting, it doesn't matter if the
formaldehyde is used or unused or is the "sole active ingredient" in order to be reportable. (Related
note: Colorado's hazardous waste regulations (6 CCR 1007-3) do not include the footnote regarding
sole active ingredients. In Colorado, chemicals may have more than one active ingredient and still
meet the listing description.)
All RCRA listed and characteristic
hazardous wastes are designated
as hazardous substances under
CERCLA.
Unlisted hazardous wastes exhibiting the characteristics of
ignitability, corrosivity and/or reactivity have a reportable
quantity of 100 pounds unless the concentrations of all the
constituents in the waste are known. If the waste is analyzed
and the concentrations of ALL its hazardous constituents are
identified, the reportable quantities of the specific constituents should be used to determine when
reporting is required. For example, a corrosive-only waste of unknown composition has a
reportable quantity of 100 pounds. If the waste is analyzed to determine that it was a 50% solution
of hydrochloric acid in water, then the reportable quantity of the solution would be 10,000 pounds.
[The reportable quantity for hydrochloric acid is 5000 pounds. Therefore it would take 10,000
pounds of the 50% solution to meet the reportable quantity for hydrochloric acid.]
Unlisted hazardous wastes that exhibit toxicity have reportable quantities specific to the constituent
on which the characteristic of toxicity is based. The reportable quantity applies to the waste itself,
not just to the toxic contaminant. If an unlisted hazardous waste exhibits toxicity on the basis of
more than one contaminant, the reportable quantity for the waste is the lowest of the reportable
quantities for those contaminants. For example, if a waste exhibits toxicity characteristics for the
heavy metals lead (D008) and selenium (D010), with reportable quantities of 10 and 100 pounds
respectively, the reportable quantity would be 10 pounds of the waste, or the lower of the two
reportable quantities. If a waste exhibits a toxicity characteristic and one or more other hazardous
waste characteristics, the reportable quantity for that waste is the lowest of the applicable reportable
quantities.
These notification and reporting requirements are included in 40 CFR Part 302.
Permitted and Interim Status Treatment, Storage and Disposal Facilities and Large
Quantity Generators of Hazardous Waste
Large quantity generators of hazardous waste and hazardous waste treatment, storage and disposal
facilities (TSDF) are required to have and implement a contingency plan that describes the actions
facility personnel must take in response to fires, explosions, or any unplanned sudden or non-
sudden release of hazardous waste or hazardous waste constituents to air, soil, surface water or
groundwater at the facility. Whenever there is an imminent or actual emergency situation,
appropriate State and local agencies with designated response roles as described in the contingency
plan must be notified immediately. Appropriate local authorities and the National Response Center
or government official designated as the regional on-scene coordinator must be notified
immediately if the facility's emergency coordinator determines that the facility has had a release,
fire, or explosion that could threaten human health or the environment outside the facility. A
treatment, storage, and disposal facility's permit generally requires reporting to the Colorado
Department of Public Health and Environment – Hazardous Materials and Waste Management
Division of any release, fire or explosion, even if the amount of the release is less than an otherwise
reportable quantity.
8
Reporting Environmental Releases in Colorado January 2009
The Department and local authorities must be notified when the facility is back in compliance and
ready to resume operations. In addition, the facility must send a written report to both the EPA
Regional Administrator and the Colorado Department of Public Health and Environment within 15
days of any incident that requires implementation of the facility contingency plan.
In the case of a release of hazardous waste stored in tanks, the facility must notify the Hazardous
Materials and Waste Management Division within 24 hours of a release to the environment of more
than one pound. A leak or spill of hazardous waste that is less than or equal to one pound from a
tank or tank system does not need to be reported if the release is immediately contained and cleaned
up. Within 30 days of the release, a written report must be submitted to the Division.
These notification and reporting requirements are included in 6 CCR 1007-3 Sections 264.56 and
265.56 and Sections 264.196(d) and 265.196(d).
D. Radiation Control
Releases of radionuclides are
reportable under CERCLA.
The state of Colorado has specific reporting requirements for stolen, lost or missing licensed or
registered sources of radiation. Each licensee or registrant must report to the Colorado Department
of Public Health and Environment by telephone in the event of lost, stolen or missing licensed or
registered radioactive materials, a lost, stolen, or missing radiation machine, releases of radioactive
materials, contamination events, and fires or explosions involving radioactive materials. Incidents
should be reported to the Radiation Incident Reporting Line. Based on the severity of the event,
notification may be required immediately, within 24 hours or within 30 days. A follow-up written
report must also be submitted to the Department within 30
days of initial notification. The licensee must also report any
additional substantive information regarding a loss or theft
incident within 30 days after learning of such information.
These release and notification requirements are contained in 6 CCR 1007-1 Sections 4.51 - 4.53.
E. Clean Water Act
The Clean Water Act (CWA) requires the person in charge of a facility or vessel to make an
immediate report to the National Response Center of discharges of harmful quantities of oil to
navigable waters as soon as they have knowledge of the release. In this case, oil means oil of any
kind or in any form including, but not limited to, petroleum, fuel oil, sludge, oil refuse, and oil
mixed with wastes other than dredged spoil. Discharges of oil that violate applicable water quality
standards and those that cause a film, sheen or discoloration of the surface of the water or adjoining
shorelines, or cause a sludge or emulsion to be deposited beneath the surface of the water or on
adjoining shorelines must be reported. In effect, this means that any discharge of oil to waters of
the United States must be reported to the National Response Center. These release and notification
requirements are contained in 40 CFR Part 110.
The Clean Water Act (CWA) also requires the person in charge of a facility or vessel to report to
the National Response Center the discharge of a designated hazardous substance from the vessel or
facility to waters of the United States in quantities that equal or exceed the reportable quantity as
soon as they have knowledge of the release. Under the Act, the US EPA was directed to establish
reporting quantities for all hazardous substances listed in Table 116.4 A and B (40 CFR Part 116),
which were designated as hazardous substances in accordance with Section 311(b)(2)(A) of the
9
Reporting Environmental Releases in Colorado January 2009
Clean Water Act. This designation includes any isomers and hydrates as well as any solutions and
mixtures containing these substances. Each of these substances is included in the CERCLA list of
hazardous substances (40 CFR Part 302 Table 302.4) and is assigned the reportable quantity listed
in Table 302.4 for that substance. These release and notification requirements are contained in 40
CFR Parts 116 and 117.
Under the Clean Water Act, anyone that has a National Pollutant Discharge Elimination System
(NPDES) permit must report to the National Response Center within 24 hours of becoming aware
of any unanticipated bypasses or upsets that cause an exceedance of the effluent limits in their
permit and any violation of their maximum daily discharge limits for any pollutant listed in the
permit. A written report must be provided within five days. Other instances of noncompliance
must be reported when monitoring reports are submitted.
The Clean Water Act also requires all industrial users of Publicly Owned Treatment Works
(POTWs) to notify their treatment plant immediately if they have a discharge that could cause
problems at the treatment plant.
These notification and reporting requirements are included in 40 CFR Parts 122 and 403.
State Requirements
A spill of any chemical, oil, petroleum product, sewage, etc., which may enter waters of the state of
Colorado (which include surface water, ground water, and dry gullies and storm sewers leading to
surface water) must be reported immediately to the Colorado Department of Public Health and
Environment. Any accidental discharge to the sanitary sewer system must be reported immediately
to the local sewer authority and the affected wastewater treatment plant. If a release occurs at a
mining operation, the Division of Reclamation, Mining and Safety should also be notified.
For more information regarding State reporting requirements under 25-8-601(2) CRS, please refer
to the “Guidance for Reporting Spills under the Colorado Water Quality Control Act and Colorado
Discharge Permits” adopted by the Water Quality Control Division. This policy is available at
http://www.cdphe.state.co.us/op/wqcc/Resources/Guidance/spillguidance.pdf.
F. Safe Drinking Water Act
The owner or operator of a public water system (community water systems, non-transient non-
community water systems, and transient non-community water systems) must immediately report
any credible threat to the water supply system to the Colorado Environmental Release and Incident
Reporting Line and to the local emergency manager. The local emergency manager may be the
county sheriff or a member of the fire department. A list of local emergency managers is available
from the Colorado Department of Local Affairs.
G. Clean Air Act
Hazardous air pollutants (HAPs) listed in Section 112(b) of the Clean Air Act (CAA) are designated
as hazardous substances under the Comprehensive Environmental Response, Compensation and
Liability Act (CERCLA). Hazardous air pollutants are known or suspected to cause cancer or other
serious health effects or adverse environmental effects. Health effects can include immunological,
neurological, reproductive, developmental, and respiratory problems. In some cases, hazardous air
10
Reporting Environmental Releases in Colorado January 2009
pollutants can be deposited onto soils or other surfaces, where they are taken in by plants and
animals and can accumulate in organic tissue or pass up the food chain due to the inability of
organisms to process the substance.
The release (or air emission) of a hazardous air pollutant that is allowed and less than any limit
specified in a facility's air permit is considered to be a federally permitted release. If the facility
releases more than is allowed under its air permit within a 24 hour period, the facility must report
the release if the quantity released exceeded the facility's permitted level by a reportable quantity or
more. For example, if a facility has an air permit that allows the release of 30 pounds of a
hazardous substance and that substance has a reportable quantity of 100 pounds, the facility would
have to report all releases of 130 pounds or more of that substance. Releases of less than 130
pounds would not need to be reported under CERCLA or EPCRA because even though the facility
exceeded its permit limit, the amount released did not exceed the permitted level by its reportable
quantity (in this case, 100 pounds) or more. If the air permit does not allow or does not specify the
release of a hazardous air pollutant, then releases in excess of the CERCLA / EPCRA reportable
quantity for that substance must be reported. Please be aware that other reporting requirements are
triggered, however, based on the facility's air permit. The Clean Air Act (CAA) requires that
permits for stationary air sources have language requiring prompt reporting of any emergencies,
upsets and deviations from what is allowed in the permit. Releases must be reported to the National
Response Center and to the Colorado Department of Public Health and Environment. Contact the
Air Pollution Control Division for details on additional air-related requirements that may also apply.
Hazardous air pollutants are included in the CERCLA list of hazardous substances in 40 CFR Part
302 and are assigned the reportable quantity listed in Table 302.4 for each substance.
State Requirements
In the case of excess emissions during an emergency or malfunction, the owner or operator must
notify the Colorado Department of Public Health and Environment as soon as possible, but no later
than noon of the next working day, and provide a written follow-up report to the Air Pollution
Control Division by the end of the facility’s next reporting period.
These notification and reporting requirements are included in 5 CCR 1001-2 Section II.E and 5
CCR 1001-5, Regulation 3 Part C, Section VII.C.
H. Underground Storage Tanks (USTs) and Aboveground Storage Tanks
(ASTs)
The reportable quantity for petroleum
from a regulated storage tank system
is 25 gallons.
Owners and operators of regulated storage tank systems
must report a release or suspected release of regulated
substances to the Division of Oil and Public Safety at the
Colorado Department of Labor and Employment within 24
hours by telephone or facsimile. If outside normal working hours or on a weekend or holiday and
emergency assistance is needed, the release can be reported to the Colorado Environmental Release
and Incident Reporting line at the Colorado Department of Public Health and Environment. Any
suspected release or release of unknown quantity is a reportable quantity unless the owner/operator
can conclusively show the release is less than the reportable quantity for the released substance.
11
Reporting Environmental Releases in Colorado January 2009
Under this program, the reportable quantity for petroleum releases is 25 gallons or more from
regulated aboveground and underground storage tank systems, or any amount that causes a sheen on
nearby surface water. This is interpreted to include releases from fuel pumps and fuel delivery
trucks while connected to the petroleum storage tank system. Releases of less than 25 gallons from
regulated petroleum storage tank systems, or a release of a hazardous substance that is less than the
CERCLA reportable quantity, do not need to be reported to the Division of Oil and Public Safety if
they are immediately contained and cleaned up. If cleanup cannot be accomplished within 24
hours, the Division of Oil and Public Safety must be notified immediately.
Spills or releases of hazardous substances in excess of the CERCLA reportable quantity from
regulated underground storage tanks must also be reported to the National Response Center and the
local fire authority immediately. Any release, regardless of quantity, that has or may impact waters
of the state (including surface water, groundwater, dry gullies leading to surface water or storm
sewers) must also be reported to the Colorado Environmental Release and Incident Reporting line
immediately.
These notification and reporting requirements are included in 7 CCR 1101-14 Article 4, 8-20.5-208
CRS and 25-8-601 CRS.
I. Hazardous Materials Transportation
Highway, Aircraft, Rail and Vessel
Federal hazardous materials transportation regulations cover the transportation of hazardous
materials by highway, aircraft, rail, and vessel. Transportation includes activities related to
transportation like loading, unloading, and temporary storage. "Hazardous material" includes
hazardous substances, hazardous wastes, marine pollutants, elevated temperature materials as
defined in 49 CFR Section 171.8, materials designated as hazardous in the Hazardous Materials
Table in 49 CFR Section 172.101 and materials that meet the criteria for hazardous classes and
division in 49 CFR Part 173.
The person in physical possession of the hazardous material during transportation must notify the
National Response Center as soon as practical, but not more than 12 hours after an incident, if as a
direct result of a hazardous material:
a person is killed or is injured and requires hospitalization,
there is an evacuation of the general public that lasts more than an hour,
a major transportation artery or facility is shut down for an hour or more,
the operational flight pattern or routine of an aircraft is altered,
there is fire, breakage, spillage, or suspected contamination involving a radioactive material,
there is fire, breakage, spillage, or suspected contamination involving an infectious
substance other than a regulated medical waste,
there is a release of a marine pollutant in a quantity exceeding 119 gallons for liquids or 882
pounds for solids,
or any situation that, in the judgment of the person in possession of the hazardous material,
should be reported even though it doesn't meet the above criteria.
Notice of incidents involving an infectious substance may be given to the Director of the Centers
for Disease Control and Prevention (1-800-232-0124) instead of notifying the National Response
Center.
12
Reporting Environmental Releases in Colorado January 2009
The person in possession of the hazardous material at the time of the incident must submit a written
report within 30 days of the incident to the US Department of Transportation. In addition, a written
report must be submitted if there is an unintentional release of a hazardous material or the discharge
of any quantity of hazardous waste even though verbal notification may not be required. If the
incident involves air transportation, a copy of the report must also be submitted to the Federal
Aviation Administration Security Field Office nearest the location of the incident.
These notification and reporting requirements are included in 49 CFR Sections 171.15 and 171.16.
State Requirements
The State also has specific requirements for reporting incidents involving hazardous materials or
nuclear materials as cargo during transportation. The driver of a motor vehicle involved in a spill of
hazardous material from a fuel tank that provides fuel for the vehicle and/or equipment on that
vehicle must immediately notify the nearest law enforcement agency. The driver of a vehicle
transporting nuclear or hazardous materials as cargo that is involved in a spill, or an incident which
may result in a potential spill, must immediately notify the nearest law enforcement agency. As
soon as possible after the initial notification of the spill or incident to the nearest law enforcement
agency, the driver or a company representative must notify the Colorado State Patrol and the 24-
hour Colorado Environmental Release and Incident Reporting Line. In addition, the driver of a
motor vehicle transporting nuclear materials as cargo must immediately notify the Colorado State
Patrol if the vehicle is involved in a crash, whether or not there is damage to the vehicle.
Report releases along a highway to the
National Response Center, nearest local
law enforcement agency, Colorado State
Patrol, and Colorado Environmental
Release and Incident Reporting Line.
If the incident involves the release of hazardous
waste, the transporter must notify the Colorado
Department of Public Health and Environment and
report the ultimate disposition of the waste to the
Department in addition to the notifications above. In
the event of a spill of hazardous waste at a transfer
facility, the transporter must notify the Colorado Department of Public Health and Environment
within 24 hours of a spill exceeding 55 gallons or if there is a fire or explosion. A written report
must be sent to the Department within 15 days after the incident.
These notification and reporting requirements are included in 8 CCR 1507-25 Parts I and IV and 6
CCR 1007-3 Part 263.
Pipelines
In Colorado, the US Department of Transportation Office of Pipeline Safety inspects, regulates, and
enforces interstate gas pipeline safety requirements. They also inspect, regulate, and enforce both
intra- and interstate liquid pipeline safety requirements in this state. Through certification by the
Office of Pipeline Safety, the Gas Pipeline Safety Division of the Colorado Public Utilities
Commission regulates, inspects, and enforces intrastate gas pipeline safety requirements. Pipeline
facilities include transmission, distribution, regulated gathering, master metered, liquefied natural
gas, and propane gas systems. Be aware that these regulations are primarily for pipeline safety. Be
sure to review other environmental release reporting requirements.
Hazardous Liquids and Carbon Dioxide
13
Reporting Environmental Releases in Colorado January 2009
Federal hazardous materials transportation regulations cover the transportation of hazardous liquids
and carbon dioxide by pipeline. In this case, hazardous liquid is limited to petroleum, petroleum
products, and anhydrous ammonia in a non-gaseous state. Petroleum includes crude oil,
condensate, natural gasoline, natural gas liquids, and liquefied petroleum gas. Petroleum product
includes flammable, toxic or corrosive products obtained from distilling and processing of crude oil,
unfinished oils, natural gas liquids, blend stocks, and other miscellaneous hydrocarbon compounds.
As early as practicable following discovery of a release of a hazardous liquid or carbon dioxide
from a pipeline system, the operator must notify the National Response Center by telephone if:
a person is killed or is injured and requires hospitalization,
there is a fire or explosion not intentionally set by the operator,
there is estimated property damage (including cost of cleanup and recovery, value of lost
product, and damage to property) exceeding $50,000,
there is pollution of any stream, river, reservoir, or other body of water that violated
applicable water quality standards, caused a discoloration of the surface of the water or
adjoining shoreline, or deposited a sludge or emulsion beneath the surface of the water or
adjoining shoreline, or
there is any situation that, in the judgment of the operator, should be reported even though it
doesn't meet the above criteria.
A written accident report must be submitted to the US Department of Transportation Office of
Pipeline Safety as soon as practicable, but not later than 30 days after discovery of a release. A
supplemental report must be submitted within 30 days if the operator receives any updates or
additions to the information originally reported.
These notification and reporting requirements are included in 49 CFR Part 195.
Natural Gas and Liquefied Natural Gas
Federal hazardous materials transportation regulations also cover the transportation of natural gas
by pipeline and activities occurring at a liquefied natural gas (LNG) facility where natural and
synthetic gas are liquefied, transferred or stored.
As early as practicable following discovery of a release of gas from a pipeline or of liquefied natural
gas or gas from a liquefied natural gas facility, but generally not to exceed two hours after
discovery, the operator must notify the National Response Center and the Colorado Public Utilities
Commission Gas Pipeline Safety Section by telephone if:
a person is killed or is injured and requires hospitalization,
there is estimated property damage (including value of lost product and damage to property)
of $50,000 or more,
there is an event that results in an emergency shutdown of a liquefied natural gas facility, or
there is any situation that, in the judgment of the operator, should be reported even though it
doesn't meet the above criteria.
As early as practicable, but not later than 30 days after discovery and verbal report of a release, the
operator must submit a written report to the US Department of Transportation Office of Pipeline
Safety. A supplemental report must be submitted within 30 days if the operator receives relevant
updates or additions to the information originally reported.
14
Reporting Environmental Releases in Colorado January 2009
These notification and reporting requirements are included in 49 CFR Part 191 and 4 CCR 723-4
Sections 4900 - 4914.
State Requirements
If there is a leak on a gas pipeline, a liquefied natural gas system, a master meter system, or a
propane system that results in the evacuation of 50 or more people from a normally occupied
building or results in the closure of a roadway, the operator must contact the Colorado Public
Utilities Commission Gas Pipeline Safety Section by telephone within two hours of discovery.
This notification requirement is contained in 4 CCR 723-4 Section 4911.
J. Oil and Gas Exploration and Production
Federal oil and gas lease surface operations are managed by the US Department of the Interior
Bureau of Land Management (BLM) in cooperation with the appropriate Federal surface
management agency or non-Federal surface owner. On National Forest System lands, the Forest
Service has approval authority for the surface use portion of Federal oil and gas operations and for
appeals related to Forest Service decisions and approvals. The BLM considers the Bureau of Indian
Affairs to be the surface management agency for all Indian lands unless a Tribe has contracted the
Bureau of Indian Affairs realty function for its lands.
“… All spills or leakages of oil, gas, salt water, toxic liquids or waste materials, blowouts, fires,
personal injuries, and fatalities shall be reported by the operator to the BLM and the surface
management agency in accordance with the requirements of Notice to Lessees NTL-3A; Reporting
of Undesirable Events, and in accordance with any applicable local requirements.
The BLM requires immediate reporting of all Class I major events, such as spills of more than 100
barrels of fluid/500 MCF of gas released; fires that consume 100 bbl or more oil or 500 MCF gas;
life threatening or fatal injury/loss of well control; release of reportable quantities of hazardous
substances; spill, venting, or fire in sensitive areas, such as parks, recreation sites, wildlife refuges,
lakes, reservoirs, streams, and urban or suburban areas” … “Volumes discharged during any of the
above incidents will be estimated as necessary. Operators must take immediate action to prevent
and control spills and the BLM, the surface management agency, and other applicable regulatory
authorities must be consulted prior to treating or disposing of wastes and spills. Operators should
become familiar with local surface management agency requirements for reporting and managing
spills and leaks. …” (BLM “The Gold Book,” Fourth Edition, Revised 2007)
State Requirements
Spills and releases of Exploration and Production (E&P) waste and produced fluids should be
controlled and contained immediately upon discovery. Impacts resulting from spills and releases
should be investigated and cleaned up as soon as practicable.
If there is a spill or release of more than 20 barrels of
E&P waste, it must be verbally reported to the Colorado
Oil and Gas Conservation Commission (COGCC) as soon
as practicable, but not more than 24 hours after discovery.
If there is a spill or release of any size that impacts or
The rules and regulations for oil and
gas exploration and production have
recently been revised. Most of these
changes become effective May 1,
2009 on federal land and April 1, 2009
on all other land.

could impact waters of the state, a residence or an occupied structure, livestock or a public byway, it
must be verbally reported to the Colorado Oil and Gas Conservation Commission as soon as
practicable, but not more than 24 hours after discovery. Spills or releases of any size that impact or
threaten to impact any surface water supply area must be reported to the Colorado Oil and Gas
Conservation Commission and to the Colorado Environmental Release and Incident Reporting Line.
If the release impacts or threatens to impact a surface water intake, it must be verbally reported to
the emergency contact for that facility immediately after discovery. The operator must notify the
affected surface owner or their appointed tenant of all reportable spills as soon as practicable, but
not more than 24 hours after discovery.
Chemical spills and releases must be reported in accordance with all applicable state and federal
laws, including the Emergency Planning and community Right-to-Know Act (EPCRA), the
Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), the Oil
Pollution Act, and the Clean Water Act.
Releases of more than 5 barrels of E&P waste, and all other reportable releases, must also be
reported on COGCC Form 19 and submitted to the Colorado Oil and Gas Conservation
Commission within 10 days after discovery of the release.
These notification requirements are contained in the Colorado Oil and Gas Conservation
Commission 900-Series Rules.
K. Polychlorinated Biphenyls
Polychlorinated biphenyls (PCBs) are managed under the Toxic Substances Control Act.
Substances with concentrations greater than or equal to 50 parts per million PCBs are regulated
under 40 CFR Part 761, which is implemented by the US Environmental Protection Agency. If a
spill of the substance directly contaminates surface water, sewers, drinking water supplies, grazing
lands, or vegetable gardens and/or the spill exceeds 10 pounds of PCBs by weight, the responsible
party must notify the EPA within 24 hours. In Colorado, contact the Region 8 Emergency Response
Spill Report Line. If the spill involves 10 pounds or less of PCBs and does not involve any of these
resources, the spill must still be cleaned up, but notification to EPA isn't required. Unless
commingled with a hazardous waste, releases of substances containing less than 50 parts per million
PCBs are regulated under Colorado's solid waste regulations 6 CCR 1007-2. The solid waste
regulations do not have specific release reporting requirements at this time.
The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) has set
the reportable quantity for PCBs at one (1) pound. Any release of oil or other substance containing
greater than or equal to one pound of PCBs must be reported to the National Response Center as
soon as the release is discovered. In addition, if the release impacts waters of the state of Colorado,
the release must be reported as per the Water Quality Control Division’s reporting policy (see
“Guidance for Reporting Spills under the Colorado Water Quality Control Act and Colorado
Discharge Permits”, http://www.cdphe.state.co.us/op/wqcc/Resources/Guidance/spillguidance.pdf).

EPA's List of Lists is a compendium of the lists of chemicals subject to reporting requirements
under the Emergency Planning and Community Right-to-Know Act (EPCRA), the Comprehensive
Environmental Response, Compensation and Liability Act (CERCLA) and chemicals listed under
section 112(r) of the Clean Air Act (CAA). Lists are also provided of Resource Conservation and
Recovery Act (RCRA) hazardous wastes and radionuclides reportable under the Comprehensive
Environmental Response, Compensation and Liability Act. These lists should be used as reference
tools, not as a definitive source of compliance information. Reporting requirements for the
Emergency Planning and Community Right-to-Know Act and the Comprehensive Environmental
Response, Compensation and Liability Act are published in the Code of Federal Regulations (CFR),
40 CFR Parts 302 and 355 respectively. Compliance information for the Clean Air Act section
112(r) is published in 40 CFR Part 68. The List of Lists is available on the Internet at
http://yosemite.epa.gov/oswer/lol.nsf/homepage.
Exploration and production (E&P) wastes are associated with operations to locate or remove oil
or gas from the ground or to remove the impurities from oil or gas.
Extremely Hazardous Substances (EHS) are chemicals that present the most serious hazards
during release (in terms of toxicity, reactivity, volatility, combustibility, and flammability) and are
regulated under the Emergency Planning and Community Right-To-Know Act (EPCRA). The
extremely hazardous substances list consists of approximately 360 substances and is included in
EPA’s List of Lists.
Facility means any building, equipment, structure, installation, containment structure, pipe, other
stationary feature, motor vehicle, rolling stock, or aircraft. Facility also includes any site where a
hazardous substance is or has been located.
Hazardous Materials are chemicals posing a hazard to human health or the environment when
transported (49 USC 5103). They include hazardous substances, hazardous wastes, marine
pollutants, elevated temperature materials, all materials in the Hazardous Materials Table (49 CFR
172.101), and materials meeting the criteria for hazard classes in part 173 of subchapter C of 49
CFR 172.101.

Hazardous Substances are chemicals posing a hazard to human health or the environment and are
regulated under the Comprehensive Environmental Response, Compensation and Liability Act
(CERCLA). The hazardous substance list is included in EPA’s List of Lists.
Reportable Quantity (RQ) is a term that applies to the amount of hazardous substances or
extremely hazardous substances released within a 24-hour period. Note that the 24-hour period is
the time frame for measuring the quantity released, not the time frame for reporting a release.
Threshold Planning Quantity (TPQ) is a term that applies to the amount of an extremely
hazardous substance that must be present onsite in concentrations greater than 1% by weight of a
compound or mixture at which the facility must meet all emergency planning requirements. If not
also listed as a CERCLA hazardous substance, extremely hazardous substances have a reportable
quantity equal to the threshold planning quantity for that substance.
“Waters of the State of Colorado” are any and all surface waters and subsurface waters
(groundwater) that are contained in or flow in or through the state of Colorado. This includes lakes,
rivers, streams, creeks, wetlands, irrigation ditches, storm drains, livestock ponds, borrow ditches,
and dry gullies. This does not include waters in sewage systems, waters in treatment works of
disposal systems, waters in potable water distribution systems, or water withdrawn for use until use
and treatment have been completed.

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