FOREWORD
This booklet provides summary guidance on the development of storm water pollution
prevention plans and identification of appropriate Best Management Practices (BMPs) for for
construction activities. It provides technical assistance and support for construction activities
subject to pollution prevention requirements established under National Pollutant Discharge
Elimination System (NPDES) permits for storm water point source discharges.
EPA's storm water program significantly expands the scope and application of the existing
NPOES permit system for municipal and industrial process wastewater discharges. It
emphasizes pollution prevention and reflects a heavy reliance on BMPs to reduce pollutant
loadings and improve water quality. This booklet provides summary guidance in both of these
areas.
The document summarized here was issued in support of EPA regulations and policy initiatives
involving the development and implementation of a National storm water program. The
document is Agency guidance only. It does not establish or affect legal rights or obligations.
Agency decisions in any particular case will be made applying the laws and regulations on the
basis of specific facts when permits are issued or regulations promulgated.
The document and this booklet will be revised and expanded periodically to reflect additional
pollution prevention information and data on treatment effectiveness of BMPs. Comments
from users will be welcomed. Send comments to U.S. EPA, Office of Wastewater

A BRIEF GUIDE TO REQUIREMENTS FOR DEVELOPING AND IMPLEMENTING
POLLUTION PREVENTION PLANS FOR CONSTRUCTION ACTIVITIES
Storm water runoff is part of the natural hydrologic cycle. However, human activities, particularly
urbanization can alter natural drainage patterns and add pollutants to the rainwater and snowmelt that run
off the earth's surface and enter our Nation's rivers, lakes, streams, and coastal waters. In fact, recent
studies have shown that storm water runoff is a major source of pollutants impairing our sport and
commercial fisheries, restricting swimming, and affecting the navigability of many of our Nation's waters.
Recognizing the importance of this problem, Congress directed the U.S. Environmental Protection Agency
(EPA) to develop a Federal program under the Clean Water Act to regulate certain high priority storm water
sources. The issuance of storm water discharge permits under the National Pollutant Discharge Elimination
System INPQES) is a major part of the Agency's efforts to restore and maintain the Nation's water quality.
Discharges of storm water runoff from construction sites which disturb 5 or more acres of land must now
be covered by an NPDES permit. To deal with the thousands of construction projects which are now
required to be covered by storm water permits, EPA strongly encourages the use of general permits.
Under the NPDES program, a general permit authorizes discharges from a number of sources. To
specifically address storm water discharges from construction sites located in the States and territories
that have not been delegated NPDES permitting authority, EPA issued NPDES General Permits for Storm
Water Discharges from Construction Sites in the September 9 and September 25, 1 992, Federal Register.
(A complete list of these States and territories to which EPA's permits apply may be found on page 17 of
this document.)
The purpose of this document is to describe the steps which must be completed in order for a construction
site to comply with the pollution prevention plan requirements contained in EPA's general permits. A
detailed manual on how to develop and implement your pollution prevention plan is available from the
National Technical Information Service (NTIS). The manual, titled Storm Water Management for
Construction Activities: Developing Pollution Prevention Plans and Best Management Practices, provides
much more specific information than this brief guide. Instructions for ordering the detailed manual and a
listing of other references that you may find useful can be found on page 1 7 of this guide. It is important
to note that permit requirements will vary from State to State and permit to permit; therefore, you should
read your permit carefully.
OVERVIEW OF POLLUTION PREVENTION PLAN REQUIREMENTS
Under the NPDES Genera/ Permits for Storm Water Discharges From Construction Sites, EPA requires the
development and implementation of a pollution prevention plan. A pollution prevention plan for
construction is designed to reduce pollution at the construction site, before it can cause environmental
problems. Many of the practices and measures required for the pollution prevention plan represent
standard operating procedure at many construction sites. Storm water management controls, erosion and
sediment controls, inspection and maintenance have all been used at a number of construction projects.
This guide is organized according to the phases of the pollution prevention planning and implementation
process. A set of checklists and a model plan at the end of the document are provided to further clarify
requirements. As shown on the chart on the following page, pollution prevention planning requirements
have been organized to provide you with a step-by-step process for ensuring that pollutants are not making
their way into the storm water discharges from your site. The six major phases of the process are (1) site
evaluation and design development, (2) assessment, (3) control selection and plan design, (4) certification
and notification, (5) construction/implementation, and (6) final stabilization/termination. In addition, all
permit holders must meet a number of general requirements.

SIX PHASES FOR DEVELOPING AND IMPLEMENTING CONSTRUCTION STORM
WATER POLLUTION PREVENTION PLANS
October 1992
Ptg« 2
-------
SITE EVALUATION AND
DESIGN DEVELOPMENT PHASE
The first phase in a preparing a Storm Water Pollution Prevention Plan for a construction project is to
define the characteristics of the site and the type of construction that will be occurring. This phase is
broken down into four requirements: (A) collect site information, IB) develop site design, (C) describe
construction activity, and ID) prepare pollution prevention site map.
(A) Collect Site Information
Prior to design, it is necessary to collect information about the existing conditions at the construction site.
The EPA General Permits require that the Pollution Prevention Plan include the following information:
• Existing soils information—Where information exists which describes the soils at the construction
site, this data must be included in the pollution prevention plan. Soils data may include soil type,
depth of the soil layer, soil texture, infiltration (percolation rate), or whether the soils are
susceptible to erosion. Sources of soils information could include soil borings or other
geotechnical investigations. Soil Conservation Service (SCSI soil surveys may also be used, and
SCS surveys typically indicate whether a soil is erodible.
• Existing runoff water quality—If storm water runoff from the proposed construction site has been
sampled and analyzed for the presence of any pollutant (e.g., total suspended solids), then the
results of the analyses must be included in the pollution prevention plan. In most cases, existing
runoff water quality data are not available for a specific site, particularly an undeveloped site.
However, if the construction site is on or adjacent to an existing industrial facility, that facility may
have collected runoff water quality data to satisfy another permit. If there are no existing data on
the quality of runoff from the site, then it is not necessary to collect or analyze storm water
samples for the Construction General Permit. Runoff water quality data may sometimes be
available from your State or local government, e.g., the local municipal separate storm sewer
authority. You may also be able to obtain runoff water quality information from the U.S.
Geological Survey IUSGS), State, or local watershed protection agencies.
• Location of surface waters on the construction site—If the construction site includes or is adjacent
to surface waters then the location and extent of the surface waters must be determined so that
they may be indicated on the pollution prevention site map. Surface waters include lakes, rivers,
streams (both perennial and intermittent), and wetlands.
• Name of receiving water—Identify the name and location of the body of water, e.g., stream,
creek, run, wetland, river, lake, bay, ocean, that will receive the runoff from the construction site.
If the receiving water is a tributary include the name of the ultimate receiving body of water if
possible. If the site drains into a Municipal Separate Storm Sewer System, identify the system and
indicate the receiving water to which the system discharges. This information is usually available
from county. State, or USGS maps.
(B) Develop Site Plan Design
Once the information on the existing site conditions is collected, it is possible to develop a site plan design.
In addition to the goals and objectives for the facilities being constructed, the designers should also
consider objectives which will limit the amount of pollution in storm water runoff from the construction
site, such as:
October 1992 P*9* 3
-------
• Disturb tne smallest area possible.
• Avoid disturbance of sensitive areas such as:
• Steep and/or unstable slopes
• Surface waters, including wetlands
- Areas with soils susceptible to erosion
• Existing drainage channels.
• Identify areas to oe preserved or left as open space.
(C) Describe Construction Activity
In preparing your plan, you must (1) describe the purpose or goal of the construction project (e.g., a single
family residential development, a multistory office building, or a highway interchange) and (2) list the soil
disturbing activities necessary to complete the project. (Soil disturbing activities might include clearing,
excavation and stockpiling, rough grading, final or finish grading, preparation for seeding or planting,
excavation of trenches, demolition, etc.).
(O) Prepare Pollution Prevention Site Map
The final step of the site evaluation and design development phase is to combine the information collected
into a comprehensive pollution prevention site map. The starting point for the pollution prevention site
map should be the site plan prepared for the construction design. The map for the construction site should
be drawn to scale with topography. The scale of the map should be small enough so that you can easily
distinguish important features such as drainage swales and control measures that will be added later. In
addition to the location of surface waters, the following information must be included on the site map:
• Slopes after grading—Indicate what the location and steepness of slopes will be after grading.
• Disturbed areas-Indicate the areas of soil disturbing activities or the total area of the site where
soil will be disturbed. Also draw an outline of areas that will not be disturbed.
• Drainage patterns/discharge points-Indicate the drainage patterns of the site after the major
grading activities and the location of the points where storm water will discharge from the site.
• To illustrate the drainage pattern of the site, use topographic contour lines or arrows to indicate
the direction runoff will flow.
- Show the location of swales or channels. If there is a new or proposed underground storm
drain system on the site, this should be indicated on the Storm Water Pollution Prevention Plan
site map as well.

-------
ASSESSMENT PHASE
Once the characteristics of the site and the construction have been defined, the next phase in
developing a Storm Water Pollution Prevention Plan is to measure the size of the land disturbance and
estimate the impact the project will have on storm water runoff from the site based on information
collected m Phase 1. Three things should be done to assess the project: (At measure the site area, IB)
measure the drainage areas, and (C) calculate the runoff coefficient.
(A) Measure the Site Area
The General Permit requires that you indicate in the Storm Water Pollution Prevention Plan estimates of the
total site area and the area that will be disturbed. The total sit* area estimate must represent the size of
the parcel of property or right of way on which the construction is occurring. The disturbed area estimate
must represent the portion of the total site area which will be disturbed over the course of the construction
project. These values can be measured from the pollution prevention site map which is drawn to scale.
(B) Determine the Drainage Areas
Although the size of each drainage area for each point where concentrated flow will leave the site is not
required to be included in the pollution prevention plan, this information will help you select and design the
sediment control and storm water management measures for your project in the next phase of the plan.
Drainage areas are portions of the site where runoff will flow in one particular direction or to a particular
discharge point. Use the drainage patterns indicated on the site map to determine the drainage areas.
(C) Calculate the Runoff Coefficient
The General Permit requires that you estimate the runoff coefficient of the site after construction is
complete. The runoff coefficient is an estimate of the fraction of total rainfall that will appear as runoff
For example, the "c* value of lawn area is 0.2, which indicates that only 20 percent of the water that falls
on grassed areas will end up as surface runoff. In contrast, the "c" value of a paved area can be 0.9 or
higher, indicating that 90 percent of the rain falling on this type of surface will run off. Runoff coefficients
for sites with more than one land us* are estimated by calculating a weighted average (based upon area) of
the runoff coefficients for each land use. Table 1 lists runoff coefficients for various land uses.

CONTROL SELECTION/PLAN
DESIGN PHASE
After you have collected the information and made measurements, the next phase is to design a plan to
prevent and control pollution of storm water runoff from your construction site. To complete the Storm
Water Pollution Prevention Plan, (A) review and incorporate State and local requirements, IB) select
erosion and sediment controls, (C) select other controls, ID) select storm water management controls.
(E) indicate the location of controls m the site map, (F) prepare an inspection and maintenance plan, (G)
prepare a description of controls, and {HI prepare a sequence of major activities. The following
subsections explain how the controls you select should be described in the Storm Water Pollution
Prevention Plan.
(A) Raview and Incorporate State and Local Requirements
If the construction site is located in a State or municipality which implements its own separate storm water
management or erosion and sediment control programs, then the pollution prevention plan prepared for
compliance with EPA's NPOES General Permit must also comply with the State or local requirements.
Therefore, prior to designing the pollution prevention plan, you must first determine what requirements, if
any, exist for sediment and erosion site plans, site permits or storm water management site plans, or site
permits. Where these requirements do exist, then they must be carefully reviewed and incorporated into
the plan design.
Consideration of State and local requirements in the plan design phase is necessary because the permit
requires that the permittee provide a certification that the pollution prevention plan reflects the
requirements applicable to protecting surface water resources in sediment and erosion sitt plans or
permits, or storm water management site plans or site permits approved by State or local officials.
(8) Select Erosion and Sediment Controls
The Storm Water Pollution Prevention Plan must include a description of the measures to be used for
erosion and sediment controls throughout the construction project. These controls include stabilization
measures for disturbed areas and structural controls to divert runoff and remove sediment. Erosion and
sediment controls are implemented during the construction period to prevent and/or control the loss of soil
from the construction site into the receiving waters. Your selection of the most appropriate erosion and
sediment controls depends on a number of factors, but is most dependent on site conditions. The
information collected in the site evaluation, design and assessment phases is used to select controls.
Some controls are discussed below:
• Stabilization-Under the EPA's General Permit disturbed areas of the construction site that will not
be redisturbed for 21 days or more must be stabilized by the 14th day after the last disturbance.
Stabilization measures include the following:
- Temporary seeding-Temporary seeding is the planting of fast-growing grasses to hold down
the soils in disturbed areas so that they are less apt to be carried offsite by storm water runoff
or wind.
- Permanent seeding—Permanent seeding is the use of permanent vegetation (grass, trees, or
shrubs) to stabilize the soil by holding soil particles in place.
- Mulching-Mulching is the placement of material such as hay, grass, woodchips, straw, or
gravel on the soil surface to cover and hold in place disturbed soils. (Mulching often
accompanies seeding.)
October 1992
-------
The EPA General Permit requires that trie pollution prevention plan include structural practices to divert
flows away from disturbed areas, to store flows, or to limit the discharge of pollutants from the site. The
following is a list of some of the practices which may be used.
• Structural control measures
- Earth Dike —An earth dike is a mound of stabilized soil which is constructed to divert runoff.
Earth dikes may be used to either divert uncontaminated runoff away from disturbed areas or to
divert contaminated runoff into a sediment basin or sediment trap.
- Silt fence—A silt fence is a temporary measure consisting of posts with filter fabric stretched
across the posts and sometimes with a wire support fence. The fence is installed along the
downslope or sideslope perimeter of a disturbed area. Runoff passes through the openings in
the fabric, while sediment is trapped on the uphill side.
- Sediment trap —A sediment trap is formed by excavating a pond or by placing an earthen
embankment across a low area or drainage swale. It has an outlet or spillway made of large
stones or aggregate. The trap retains the runoff long enough to allow the silt to settle out.
- Sediment basin—A sediment basin is a settling pond with a controlled water release structure,
e.g., a riser and pipe outlet with a gravel filter, which slows the release of runoff. The basin
detains sediment-laden runoff from larger drainage areas long enough for most of the sediment
to settle out.
The EPA General Permit requires that, where it is attainable, a temporary or permanent sediment basin be
installed m any drainage location where more than 10 acres in the upstream drainage area are disturbed at
one time. The sediment basin must provide at least 3,600 cubic feet of storage for every acre of land
which it drains (flows from upland areas that are undisturbed may be diverted around the basin!. For
drainage locations with 10 or fewer disturbed acres, sediment traps, filter fences, or equivalent measures
must be installed along the downhill boundary of the construction site.
(C) Select Other Controls
In addition to erosion and sediment controls, the Pollution Prevention Plan for your project must address
the other potential pollutant sources that may exist on a construction sit*. These controls include proper
disposal of construction site wast* disposal, compliance with applicable State or local waste disposal,
sanitary sewer or septic system regulations, control of offsite vehicle tracking, and control of allowable
non-storm water discharges, as explained in the following bullets:
• Ensure proper disposal of construction site waste materials.
• Treat or dispose of sanitary wastes that are generated onsita in accordance with Stats or local
requirements. Contact the local government or Stats regulatory agency.
• Prevent offsite tracking of sediments and generation of dust. Stabilized construction entrances or
vehicle washing racks should be installed at locations where vehicles leave the site. Where dust
may be a problem, implement dust control measures such as irrigation.
• Identify and prevent contamination of non-storm water discharges. Where non-storm water
discharges allowed by the General Permit exist, they must be identified and steps must be taken to
prevent contamination of these discharges.
Octobtr 1992 ?«?• 8
-------
(D) Select Storm Water Management Controls
Storm water management controls are constructed to prevent or control pollution of storm water after the
construction is completed. The General Permit requires that the pollution prevention plan include a
description of the measures that wilt be installed to control pollutants in storm water after construction is
complete. For sites m which the development results in runoff flows that are higher than pre-construction
levels, the pollution prevention plan must include a technical explanation of why a particular storm water
management measure was selected. These controls include, but are not limited to, one or more of the
following:
• Retention pond —A pond that holds runoff in a reservoir without release except by means of
evaporation, infiltration, or emergency bypass.
• Detention pond —A pond that holds or detains runoff in a basin for a limited time releasing it slowly
to allow most of the sediments to drop out.
• Infiltration measures-Measures that allow the percolation of water though the ground surface into
subsurface soil. Specific measures include infiltration trenches, basins, and dry wells.
• Vegetated swales and natural depressions—Grass-linnd ditches or depressions that transport
runoff, filter sediments from the runoff, and enhance infiltration of the runoff.
Selection of the most appropriate storm water management measures depends upon a number of factors
associated with site conditions. EPA expects that most sites can employ measures to remove 80 percent
of the total suspended solids from post-construction runoff. When you select storm water management
measures for a development project, consider the impacts of these measures on other environmental media
(e.g., land, air, and ground water).
In addition to pollutant removal, the storm water management portion of the plan must address velocity
dissipation at discharge locations. Development usually means an increase in speed with which the site
will drain because of the addition of paved areas, storm sewers, curbs, gutters, etc. The General Permit
requires that velocity dissipation devices be placed along the length of any outfall where the discharge
from the developed area may erode the channel. The potential for erosion is primarily dependent upon the
velocity of the storm water discharge and the type of material that lines the channel. One velocity
dissipation device is riprap outlet protection, which is stone or riprap placed at the discharge point to
reduce the speed of concentrated storm water flows.
(E) Indicate the Location of Controls on the Site Map
Pollution prevention measures must be shown on the pollution prevention site map, including the location
of each measure used for erosion and sediment control, storm water management, and other controls.
When this has been done, the site map is ready to be included in the Pollution Prevention Plan. Note: It
may not be feasible to indicate some controls on the site map, e.g., waste control measures.
(F) Prepare an Inspection and Maintenance Plan
After the Storm Water Pollution Prevention Plan is prepared and the necessary controls are installed*, you
will be responsible for inspecting and maintaining them. The General Permit requires that you prepare a
description of the procedures to maintain the pollution prevention measures onsite. An inspection and
maintenance checklist for each of the control measures proposed for the construction site should be
included in the Storm Water Pollution Prevention Plan prior to starting construction.
October 1992
-------
(G) Prepare a Description of Controls
Once you have finished planning your construction activities and selected the controls, make a list of each
type of control you plan to use on the site. Include a description of each control, describe its purpose, and
explain why it is appropriate in this location. The description should also include specific information about
the control such as size, required materials, and methods of installation/use. Read your permit carefully to
ensure that your plan includes all of the required controls.
(H) Prepare a Sequence of Major Activities
You must prepare a sequence of major activities that includes the installation of all the controls, earth
disturbing activities, all stabilization activities, and the maintenance required for the controls. The
sequence should clearly indicate the order in which each of the activities described takes place. Several
general principles are helpful in developing the sequence of major activities:
• Install downslope and sideslope perimeter controls before the land disturbing activity occurs.
• Do not disturb an area until it is necessary for construction to proceed.
• Cover or stabilize disturbed areas as soon as possible.
• Time construction activities to limit impact from seasonal climate changes or weather events.
• Delay construction of infiltration measures until the end of the construction project when upstream
drainage areas have been stabilized.
• Do not remove temporary perimeter controls until after all upstream areas are finally stabilized.

-------
CERTIFICATION AND
NOTIFICATION PHASE
Once the site description and controls portion of the Storm Water Pollution Prevention Plan have been
prepared. YOU now must (A) certify the pollution prevention plan and (B) submit a Notice of Intent to
the appropriate agency The checklist provided at the end of this document will be very useful in
evaluating whether all the required items are included in your Storm Water Pollution Prevention Plan
prior to certifying the plan or submitting a Notice of Intent.
(A) Certify the Pollution Prevention Plan
Once a pollution prevention plan is prepared, the EPA General Permit requires that the plan be certified.
The plan should identify an Authorized representative for each operator to sign the plan. The authorized
representative must be someone at or near the top of the management chain, such as the president, vice
president, or a general partner, who has been delegated the authority to sign and certify this type of
document. In signing the plan, the authorized representative certifies that the information is true and
assumes liability for the plan. Note that Section 309 of the Clean Water Act provides for significant
penalties where information is false or the permittee violates, either knowingly or negligently, permit
requirements.
In addition to the party or parties considered to be operators, construction activities often have a number
of different short-term contractors and subcontractors coming onsite during each phase of trie project
development. The EPA General Permit requires that the contractors and subcontractors responsible for
implementing measures in the Pollution Prevention Plan be listed in the plan with the measures for which
they are responsible and that they sign a certification statement that they understand the permit
requirements.
(B) Submit a Notice of Intent
The General Permit for Storm Water Discharges Associated with Industrial Activity from Construction
Activities requires that you submit a Notice of Intent (NOD at least 2 days before construction activities
begin. The NOI is essentially an application and contains important information about your site, including
site location, owner information, operator (general contractor) information, receiving water(s), existing
NPDES Permit Number (if any), an indication of existing quantitative data, and a brief description of the
project.
EPA has developed a one-page form to be used by industrial facilities and construction activities when they
submit NOls. This form indicates all the information that you are required to provide and must be used in
order for the NOI to be processed correctly. NOls for the EPA General Permit will be submitted directly to
EPA's central processing center at the following address:
Storm Water Notice of Intent
P.O. Box 1215
Newington, VA 22122
Each party or each of the parties who have day-to-day responsibilities for site operations, and each party or
each of the parties who have control over the designs and specifications necessary to ensure compliance
with plan requirements and permit conditions, must submit an NOI. It is anticipated that there will be
projects where more than one entity (e.g., the owner, developer, or general contractor) will need to submit
1992 Ptg» 11

an NO) so that both of the requirements for an operator are met. In this case, those persons will become
co-permittees.
Deadlines —There are different deadlines for submitting NOls depending on whether the construction
starts before or after October 1, 1992.
• Before October 1. 1992-For construction activities that have started before October 1, 1992,
and plan to continue beyond this date, the NOI must be submitted on or before October 1, 1992.
• After October 1, 1992-if construction will not begin until after October 1, 1992, an NOI must be
postmarked at least 2 days before construction begins.
• The Storm Water Pollution Prevention Plan must be completed prior to the submittal of an NOI.

CONSTRUCTION/
IMPLEMENTATION PHASE
Once you have prepared a Storm Water Pollution Prevention Plan and filed a Notice of Intent, you may
start construction of the project as early as 2 days after the NOI is postmarked. However, you have
not vet met all requirements of your permit. You must now do the things that you said you would do
m the Storm Water Pollution Prevention Plan: (A) implement the controls, (Bl inspect and maintain the
controls, (C) maintain records of construction activities, (0) update/change the plan to keep it current,
(E) take proper action when there is a reportable quantity spill, and (F) have plans accessible.
(A) Implement Controls
The first action that should be taken is to construct or perform the controls that were selected for the
Storm Water Pollution Prevention Plan. The controls should be constructed or applied in accordance with
State or local specifications. If there are no State or local specifications for control measures, then the
controls should be constructed in accordance with good engineering practices. The controls must be
constructed in the order indicated in the sequence of major activities. Stabilization measures must be
applied within the timeframe specified in the permit.
To ensure that controls are adequately implemented, it is important that the work crews who install the
measures are experienced and/or adequately trained. Improperly installed controls can have little or no
effect and may actually increase the pollution of storm water. It is also important that all other workers on
the construction site be made aware of the controls so that they do not inadvertently disturb or remove
them.
(B) Inspect and Maintain Controls
As discussed previously, inspection and maintenance of the protective measures that are part of this plan
are as important to pollution prevention as proper planning, design/selection, and installation.
• Inspection—The EPA General Permit requires inspection every 7 days or within 24 hours of a
storm of 0.5 inches or more in depth. All disturbed areas of the site, area* for material storage,
locations where vehicles enter or exit the site, and all of the erosion and sediment controls that
were identified as part of the plan must be inspected. Controls must be in good operating
condition until the area they protect has been completely stabilized and the construction activity is
complete.
• Maintenance/repair*—The inspector must record any damages or deficiencies in the control
measure* on an inspection report form provided for this purpose. These reports document the
inspection of the pollution prevention measures. These same forms can be used to request
maintenance and repair and to prove that inspection and maintenance were performed. The
operator should correct damage or deficiencies as soon as practicable after the inspection but in no
case later than 7 days after the inspection. Any changes that may be required to correct
deficiencies in the Storm Water Pollution Prevention Plan should also be made as soon as
practicable after the inspection but in no case later than 7 days after the inspection.
October 1992 P»g9 13
-------
(C) Maintain Records of Construction Activities
In addition to the inspection and maintenance reports, the operator should keep records of the construction
activity on the site. In particular, the operator should keep a record of the following information:
• The dates when major grading activities occur m a particular area.
• The dates when construction activities cease in an area, temporarily or permanently.
• The dates when an area is stabilized, temporarily or permanently.
These records can be used to make sure that areas where there is no construction activity will be stabilized
within the required timeframe.
(0) Update/Change the Plan
For a construction activity to be in full compliance with its NPDES storm water permit, and for the Storm
Water Pollution Prevention Plan to be effective, the plan must accurately reflect sit* features and
operations. When it does not, the plan must be changed. The plan must also be changed if the operator
observes that it is not effective in minimizing pollutant discharge from the site.
If, at any time during the effective period of the permit, the permitting authority finds that the plan does
not meet one or more of the minimum standards established by the General Permit, the permitting
authority will notify the permittee of required changes necessary to bring the plan up to standard.
(E) Report Releases of Reportable Quantities
Because construction activities may handle certain hazardous substances over the course of the project,
spills of these substances in amounts that equal or exceed Reportable Quantity IRQ) levels are a possibility.
EPA has issued regulations that define what reportable quantity levels are for oil and hazardous
substances. These regulations are found at 40 CFR Part 110, 40 CFR Part 117, or 40 CFR Part 302. If
there is a RQ release during the construction period, then you must take the following steps:
• Notify the National Response Center immediately at (800) 424-8802; in Washington, D.C., call
(202) 426-2675.
• Within 14 days, submit a written description of the release to the EPA Regional office providing
the daw and circumstances of the release and the steps to be taken to prevent another release.
• Modify the pollution prevention plan to include the information listed above.
(F) Provide for Plan Location and Access
The General Permit has specific requirements regarding plan location and access.
• Plan location—A copy of the Pollution Prevention Plan must be kept at the construction site from
the time construction begins until the site is finally stabilized.
• Retention of records—Retention of records requires that copies of the Storm Water Pollution
Prevention Plan and all other reports required by the permit, as well as all of the data used to
complete the NOI be retained for 3 years after the completion of final site stabilization.
October 1992 P»9» 1*
-------
Access—Although plans and associated records are not necessarily required to be submitted to the
Director, these documents must be made available upon request to the Director, or any State or
local agency who is approving erosion and sediment control plans, or storm water management
plans. If site storm water runoff is discharged to a municipal separate storm sewer system, the
plans must be made available upon request to the municipal operator of the system.
October 1992 P*ff* '5
-------
FINAL STABILIZATION/
TERMINATION PHASE
Operators of a construction site must continue to comply with permit conditions until: (1) they no
longer meet the definition of an operator of a construction site; or (2) the construction activity is
complete, all disturbed soils have been finally stabilized, and temporary erosion and sediment controls
have been or will be removed. A permittee should submit a Notice of Termination (NOT) to inform EPA
that he/she is no longer an operator of a construction activity.
Final stabilization-Final stabilization is defined by the EPA General Permit as meaning that all soil
disturbing activities at the site have been completed, and that a uniform perennial vegetative cover with a
density of 70 percent of the cover for unpaved areas not covered by permanent structures has been
established or equivalent permanent stabilization measures (such as the use of riprap, gabions, or
geotextiles) have been employed.
Notice of Termination—The NOT is a one-page form which should be completed and submitted to EPA
when a site has been finally stabilized or when an operator of a construction activity changes. Information
to be included on the NOT includes the location of the construction site; the name, address, and telephone
number of the operator terminating coverage; the NPDES general permit number; an indication of why
coverage under the permit should be terminated for the operator; and a signed certification statement.
Note that when there is a change in operators of a construction activity, then the new operator must
submit an NOI to be covered by the permit at least 2 days before the change in operator.
NOT's should be mailed to the following address:
Storm Water Notice of Termination
P.O. Box 1185
Newington, Virginia 22122
Record Retention — Following the termination of construction activities the permittees must keep a copy of
the Storm Water Pollution Prevention Plan and records of all the data used to complete tht Notice of Intent
for a period of at least thre* years following final stabilization. The record retention period may be
extended by EPA's request.

CONTROLS
Erosion and Sediment Controls
Stabilization Practices
Temporary Stabilization • Top soil stock piles and disturbed portions of the site where construction activity
temporarily ceases for at least 21 days will be stabilized with temporary seed and mulch no later than 14 days
from the last construction activity in that area. The temporary seed shall be Rye (grain) applied at the rate of
120 pounds per acre. Prior to seeding, 2,000 pounds of ground agricultural limestone and 1,000 pounds of 10-
10-10 fertilizer shall be applied to each acre to be stabilized. After seeding, each area shall be mulched with
4,000 pounds per acre of straw. The straw mulch is to be tacked into place by a disk with blades set nearly
straight. Areas of the site which are to be paved will be temporarily stabilized by applying geotextile and stone
sub-base until bituminous pavement can be applied.
Permanent Stabilization - Disturbed portions of the site where construction activities permanently 'ceases shall
be stabilized with permanent seed no later than 14 days after the last construction activity. The permanent
seed mix shall consist of 80 Ibs/acre tall fescue, and 40 Ibs/acre kobe lespedeza. Prior to seeding, 4,000
pounds of ground agricultural limestone and 2,000 pounds of 10-10-10 fertilizer shall be applied to each acre to
be stabilized. After seeding, each area shall be mulched with 4,000 pounds per acre of straw. The straw
mulch is to be tacked into place by a disk with blades set nearly straight. _^___

CONTROLS (Continued)
Structural Practice*
Eanft Dike - will b« constructed along the uphill perimeter (nonhl of the site. A portion of the dike will divert
runon around the construction site. The remaining portion of the dike will collect runoff from the disturbed area
and direct the runoff to the sediment basin.
Sediment Basin - will be constructed at the common drainage location on the south side of the construction
site. The basin will be formed by constructing an embankment across an existing gully and excavating a
storage pond with a volume of 36,000 cubic feet (0.82) acre feet. The basin will drain through a corrugated
metal riser and outlet pipe to a rip rap outlet apron. Once construction activities are nearly complete, the
accumulated sediment will be removed from the basin.
Storm Water Management
Storm water drainage will be provided by curb and gutter, storm sewer and catch basin, for the developed
areas. The areas which are not developed will be graded at less that 0.5:1 and have permanent seeding or
plantings. Two acres of the site will remain untouched and in its natural State. When construction is complete
the entire site will drain to a wet detention basin. The wet detention basin will be in the location of the
temporary sediment basin. When upslope areas are stabilized, the accumulated sediment will be removed from
the sediment basin, and the areas on the sides of the basin will be planted with vegetation. The wet detention
pond is designed with a permanent pool volume of 0.82 (acre-feet). This ie equivalent to one inch of runoff for
the entire drainage area. It is expected that this wet detention pond design will result in an 80 percent removal
of total suspended solids from the site's storm water runoff. The pond has been designed by a professional
engineer to keep peak flow rates from the two and ten year/24 hour storms at their pre-development rates.
The outlet of the detention basin will be stabilized by a riprap apron.
OTHER CONTROLS
Waste Disposal:
Waste Materials
All waste materials will be collected and stored in a securely lidded metal dumpster rented from the AOF Waste
Management Company, which is a licensed solid waste management company in Center City. The dumpster
will meet all local Center City and any State solid waate management regulations. All trash and construction
debris from the site will be deposited in the dumpster. The dumpster will be emptied a minimum of twice per
week or more often if necessary, and the trash will be hauled to the) Center City Dump. No construction waste
materials will be buried onsite. All personnel will be instructed regarding the correct procedure for waste
disposal. Notices stating these practices will be posted in the office trailer and Mr. Doe, the individual who
manages the day-to-day site operations, will be responsible for seeing that these procedures are followed.
Hazardous Waste
All hazardous waste materials will be disposed of in the manner specified by local or State regulation or by the
manufacturer. Site personnel will be instructed in these practices and Mr. Doe, the individual who manages
day-to-day site operations, wiH be responsible for seeing that these practices are followed.
Sanitary Waste
All sanitary waste will be collected from the portable units a minimum of three times per week by the TIOEE
Company, a licenced Center City sanitary waste management contractor, as required by local regulation.
Offsite Vehicle Tracking: [
A stabilized construction entrance has been provided to help reduce vehicle tracking of sediments. The paved
street adjacent to the site entrance will be swept daily to remove any excess mud, dirt or rock tracked from the
site. Dump trucks hauling material from the construction site will be covered with a tarpaulin.

-------
TIMING OF CONTROLS/MEASURES
A* indicated in the Sequence of Major Activities, the earth dike, stabilized construction entrance and sedime —
basin will be constructed prior to clearing or grading of any other portions of the site. Areas where
construction activity temporarily ceases for more than 21 days will be stabilized with a temporary seed and
mulch within 14 days of the last disturbance. Once construction activity ceases permanently in an area, that
area will be stabilized with permanent seed and mulch. After the entire site is stabilized, the accumulated
sediment will be removed from the trap and the earth dike will be removed.
CERTIFICATION OF COMPLIANCE WITH FEDERAL. State, AND LOCAL REGULATIONS
The storm water pollution prevention plan reflects Center City requirements for storm water management and
erosion and sediment control, as established in Center City ordinance 5-188. To ensure compliance, this plan
was prepared in accordance with the Center Citv Storm Water Management. Erosion and Sediment Control
Handbook, published by the Center City Department of Planning, Storm Water Management Section. There are
no other applicable State or Federal requirements for sediment and erosion site plans (or permits), or storm
water management site plans lor permits).
MAINTENANCE/INSPECTION PROCEDURES
Erosion and Sediment Control Inspection and Maintenance Practices
These are the inspection and maintenance practices that will be used to maintain erosion and sediment
controls.
• Less then one half of the site will be denuded at one time.
• All control measures will be inspected at least once each week and following any storm event of 0.5
inches or greater.
• All measures will be maintained in good working order; if a repair is necessary, it will be initiated within
24 hours of report.
• Built up sediment will be removed from silt fence when it has reached one-third the height of the feno
• Silt fence will be inspected for depth of sediment, tears, to see if the fabric is securely attached to the
fence posts, and to see that the fence posts are firmly in the ground.
• The sediment basin will be inspected for depth of sediment, and built up sediment will be removed when
it reaches 10 percent of the design capacity or at the end of the job.
• Diversion dike will be inspected and any breaches promptly repaired.
• Temporary and permanent seeding and planting will be inspected for bare spots, washouts, and healthy
growth.
• A maintenance inspection report will be made after each inspection. A copy of the report form to be
completed by the inspector is attached.
• Mr. Doe, ah* superintendent will select three individuals who will be responsible for inspections,
maintenance and repair activities, and filling out the inspection and maintenance report.
• Personnel selected for inspection and maintenance responsibilities will receive training from Mr. Doe.
They will be trained in all the inspection and maintenance practices necessary for keeping the erosion and
sediment controls used onsite in good working order.
