7.15 Removal ofBMPs

Remove erosion and sediment control BMPs that are no longer needed and leave in good working order those BMPs that will remain at the construction site after close-out.

BMPs are no longer needed when the site that the BMP is protecting has reached final stabilization as defined in the applicable NPDES Stormwater Permit.

Final stabilization means:

• All ground disturbing activities at the site have been completed, AND

• Vegetation has been established that provides a uniform perennial vegetative cover with a density of 70% of the natural vegetative cover prior to construction.

• In arid (0-1 O" annual precipitation) or semiarid ( 10-20" annual precipitation) areas, fmal stabilization is considered to be achieved when the area is seeded or planted and vegetation is expected to provide 70% cover within 3 years; AND, erosion controls are in place that provide soil protection for at least 3 years without active maintenance.

Document arid/semi-arid conditions in SWPPP

• Effective non-vegetative stabilization is in-place such as rip rap, gabions, geotextiles, rock, aggregate etc.

7.16 Post Construction Measures

Implementation: Prior to construction activities and throughout construction.

8.5 Material Handling and Waste Management

Measures will be put in place and maintained to prevent the discharge of solid materials to receiving waters, except as authorized by a permit issued under the §404 permit.

• Designated trash and bulk waste-collection areas on-site (location of areas are shown and updated on plan sheets, 6).

• Litter and debris from the construction will be cleaned up on a daily basis.

• Waste-collection areas will be located away from streets, gutters, watercourses, and storm drains. Secondary containment around waste collection areas will be implemented if needed to further minimize the likelihood of contaminated discharges.

• Portable restrooms will be located away from streets, gutters, watercourses, and storm drains (location of areas are shown and updated on plan sheets, 6). Secondary containment around waste collection areas will be implemented if needed to further minimize the likelihood of contaminated discharges.

• Portable restrooms will have tie-downs or stake downs in areas of high winds or susceptibility to vandalism.

• Hazardous waste-collection areas will be designated on-site (location of areas are shown and updated on plan sheets, 6). Secondary containment around waste collection areas will be implemented if needed to further minimize the likelihood of contaminated discharges.

• Hazardous waste containers will be routinely inspected to ensure that all containers are labeled properly and that no leaks are present.

Implementation: Throughout construction.

[29]

9.1 Inspection Frequency

Inspections will be conducted in accordance with one of the two schedules:

D . At least once every 14 calendar days and within 24 hours of the end of a storm event of 0.25 inches or greater, as determined by an on-site rain gauge.

Other schedule as allowed by State NPDES Permit.

Specify schedule: Click here to enter text.

Inspection frequency may be reduced to at least once every month if:

• The entire site is temporarily stabilized,

• Runoff is unlikely due to winter conditions (e.g., site is covered with snow, ice, or the ground is frozen), or

• Construction is occurring during seasonal arid periods in arid areas and semi-arid areas.4

A waiver of the inspection requirements is available, as authorized by the NPDES STORMW ATER PERMIT, until one month before thawing conditions are expected to result in a discharge if all of the following requirements are met:

• The project is located in an area where frozen conditions are anticipated to continue for extended periods of time (i.e., more than one month);

• Land disturbance activities have been suspended; and

• The beginning and ending dates of the waiver period are documented in the SWPPP.

• See individual EPA/State CGP for other requirements

Inspections will be conducted by qualified personnel as required in SCR Section 157. Inspector qualifications are documented in 12.

The WFL Inspection Report template will be used for all inspections. All completed Inspection Reports will be signed in accordance with the applicable EPA/State CGP and SCR 107.0IA.

Completed Inspection Reports are filed in

4 "Arid Areas" means areas with an average annual rainfall of 0 to I 0 inches. "Semi-Arid Areas" means areas with an average annual rainfall of I 0 to 20 inches.

2. EFFLUENT LIMITATIONS APPLICABLE TO ALL DISCHARGES FROM CONSTRUCTION SITES

You are required to comply with the following effluent limitations in this Part for discharges from your site and/or from construction support activities Part 1.3.c).

Note: If your project is an "existing project" (see Part 1 .4.2.b) or if you are a "new operator of an existing project" (see Part 1.4.2.c), and it is infeasible for you to comply with a specific requirement in this Part because (I) the requirement was not part of the permit you were previously covered under (i.e., the 2003 or 2008 CGP), and (2) because you are prevented from compliance due to the nature or location of earth disturbances that commenced prior to February 16, 2012, or because you are unable to comply with the requirement due to the manner in which stormwater controls have already been installed or were already designed prior to February 16, 2012, you are required to document this fact in your SWPPP and are waived from complying with that requirement. This flexibility applies only to the requirements in Parts 2.1, and 2.3.3 through 2.3.5 (except for Parts 2.3.3.1, 2.3.3.2b, 2.3.3.3c.i, and 2.3.3.4). This only applies to those portions of your site that have already commenced earth-disturbing activities or where stormwater controls implemented in compliance with the previous permit have already been installed.

Part 2 includes the following types of requirements:

• Erosion and Sediment Control Requirements jPart 2.1 )

• Stabilization Requirements (Part 2.2)

Pollution Prevention Requirements (Part 2.3)

2.1. EROSION AND SEDIMENT CONTROL REQUIREMENTS.

You must design, install, and maintain erosion and sediment controls that minimize the discharge of pollutants from earth-disturbing activities. To meet this requirement, you must comply with the following provisions.

2.1.1. General Requirements Applicable to All Construction Sites.

2.1.1. l Area of Disturbance. You are required to minimize the amount of soil exposed during construction activities. You are also subject to the deadlines for temporarily and/or permanently stabilizing exposed portions of your site pursuant to Part 2.2.

2.1 . 1 .2 Design Requirements.

a. You must account for the following factors in designing your stormwater controls:

i. The expected amount, frequency, intensity, and duration of precipitation;

ii. The nature of stormwater runoff and run-on at the site, including factors such as expected flow from impervious surfaces, slopes, and site drainage features. If any stormwater flow will be channelized at your site, you must design stormwater controls to control both peak flowrates and total stormwater volume to minimize erosion at outlets and to minimize downstream channel and streambank erosion; and

iii. The range of soil particle sizes expected to be present on the site.

b. You must direct discharges from your stormwater controls to vegetated areas of your site to increase sediment removal and maximize stormwater

Page8of60 infiltration, including any natural buffers established under Part 2.1.2.1, unless infeasible. Use velocity dissipation devices if necessary to prevent erosion when directing stormwater to vegetated areas.

2.1 .1.3 Installation Requirements.

a. Complete installation of stormwater controls by the time each phase of earth~disturbance has begun, unless infeasible. By the time earth-disturbing activities in any given portion of your site have begun, unless infeasible, you must install and make operational any downgradient sediment controls (e.g., buffers or equivalent sediment controls, perimeter controls, exit point controls, storm drain inlet protection) that control discharges from the initial site clearing, grading, excavating, and other land-disturbing activities.

Note: Where it is infeasible to install stormwater controls prior to the initial earth disturbance, it is EPA 's expectation that it will be a rare circumstance that will prevent the operator from installing such controls immediately following the initial earth disturbance.

Following the installation of these initial controls, all other stormwater controls planned for this portion of your site and described in your SWPPP must be installed and made operational as soon as conditions on the site allow.

Note: The requirement to install stormwater controls prior to earth-disturbance for each phase of the project does not apply to the earth disturbance associated with the actual installation of these controls.

b. Use good engineering practices and follow manufacturer's specifications.

You must install all stormwater controls in accordance with.good engineering practices, including applicable design specifications.

Note: Design specifications may be found in manufacturer specifications and/or in applicable erosion and sediment control manuals or ordinances. Any departures from such specifications must reflect good engineering practice and must be explained in your SWPPP.

2.1.1.4 Maintenance Requirements.

a. You must ensure that all erosion and sediment controls required in this Part remain in effective operating condition during permit coverage and are protected from activities that would reduce their effectiveness.

b. You must inspect all erosion and sediment controls in accordance with the applicable requirements in Part 4.1, and document your findings in accordance with Part 4.1.7. If you find a problem (e.g., erosion and sediment controls need to be replaced, repaired, or maintained), you must make the necessary repairs or modifications in accordance with the following schedule:

L Initiate work to fix the problem immediately after discovering the problem, and complete such work by the close of the next work day, if the problem does not require significant repair or replacement, or if the problem can be corrected through routine maintenance.

ii. When installation of a new erosion or sediment control or a significant repair is needed, you must install the new or modified control and make it operational, or complete the repair, by no later than 7 calendar days from the time of discovery where feasible. If it

a. Installation Requirements. Install inlet protection measures9 that remove sediment from your discharge prior to entry into the storm drain inlet.

Note: Inlet protection measures can be removed in the event of flood conditions or to prevent erosion.

b. Maintenance Requirements. Clean, or remove and replace, the protection measures as sediment accumulates, the filter becomes clogged, and/or performance is compromised. Where there is evidence of sediment accumulation adjacent to the inlet protection measure, you must remove the deposited sediment by the end of the same work day in which it is found or by the end of the following work day if removal by the same work day is not feasible.

2.1.3. Requirements Applicable Only to Sites Using These Specific Stormwater Controls.

You are required to comply with the following requirements if you will install any of the following stormwater controls at your site:

2.1.3. l Constructed Stormwater Conveyance Channels. Design stormwater conveyance channels to avoid unstabilized areas on the site and to reduce erosion, unless infeasible. Minimize erosion of channels and their embankments, outlets, adjacent streambanks, slopes, and downstream waters during discharge conditions through the use of erosion controls and velocity dissipation devices io within and along the length of any constructed stormwater conveyance channel, and at any outlet to provide a non-erosive flow velocity.

2.1.3.2 Sediment Basins. If you install a sediment basin , you must comply with the following:

a. Design requirements.

i. Provide storage for either (l) the calculated volume of runoff from a 2-year, 24-hour storm (see Appendix HJ, or {2) 3,600 cubic feet per acre drained;

ii. When discharging from the sediment basin, utilize outlet structures that withdraw water from the surface in order to minimize the discharge of pollutants, unless infeasible;

Note: EPA believes that the circumstances in which it is infeasible to design outlet structures in this manner are rare. Exceptions may include areas with extended cold weather, where surface outlets may not be feasible during certain time periods (although it is expected that they would be used during other periods). If you have determined that it is infeasible to meet this requirement, you must provide documentation in your SWPPP to support your determination.

iii. Prevent erosion of ( l ) the sediment basin using stabilization controls (e.g., erosion control blankets}, and {2) the inlet and outlet using erosion controls and velocity dissipation devices; and

9 Examples of inlet protection measures include fabric filters, sandbags, concrete blocks, and gravel barriers.

10 Examples of velocity dissipation devices include check dams, sediment traps, riprap, or grouted riprap at outlets.

to complete the stabilization activities specified in Parts 2.2. l .2a and/or

2.2. 1 .2b within 7 calendar days after the temporary or permanent cessation of earth-disturbing activities.

Note: If you qualify for the deadlines for initiating and completing stabilization in Part 2.2.1.3a orb, you may comply with the stabilization deadlines in Part 2.2. l .3a orb for any portion of your site that discharges to a sensitive water.

2.2.2. Criteria for Stabilization.

To be considered adequately stabilized, you must meet the criteria below depending on the type of cover you are using, either vegetative or non-vegetative.

2.2.2.1 Vegetative Stabilization.

a. For all sites, except those located in arid or semi-arid areas or on agricultural lands.

i. If you are vegetatively stabilizing any exposed portion of your site through the use of seed or planted vegetation, you must provide established uniform vegetation (e.g., evenly distributed without large bare areas), which provides 70 percent or more of the density of coverage that was provided by vegetation prior to commencing earth-disturbing activities. You should avoid the use of invasive species;

ii. For final stabilization, vegetative cover must be perennial; and

iii. Immediately after seeding or planting the area to be vegetatively stabilized, to the extent necessary to prevent erosion on the seeded or planted area, you must select, design, and install non-vegetative erosion controls that provide cover (e.g., mulch, rolled erosion control products) to the area while vegetation is becoming established.

b. For sites located in arid or semi-arid areas, or drought-stricken areas. If you are located in an arid or semi-arid area, or a drought-stricken area, as these terms are defined in Appendix A, you are considered to have completed final stabilization if both of the following criteria are met:

i. The area you have seeded or planted must within 3 years provide established vegetation that covers 70 percent or more of the density of vegetation prior to commencing earth-disturbing activities; and

ii. In addition to seeding or planting the area to be vegetatively stabilized, to the extent necessary to prevent erosion on the seeded or planted area, you must select, design, and install non-vegetative erosion controls that provide cover for at least 3 years without active maintenance by you.

c. For sites located on land used for agriculture. Disturbed areas on land used for agricultural purposes (e.g., pipelines across crop or range land, staging areas for highway construction) that are restored to their pre construction agricultural use are not subject to these final stabilization criteria. Areas disturbed that were not previously used for agricultural activities, and areas that are not being returned to preconstruction agricultural use, must meet the conditions for stabilization in this Part.
