DA DB De ~n DE

Criterion A.

Criterion B.

Criterion C

Criterion D.

No federally-listed threatened or endangered species or their designated critical habitat(s) are likely to occur in your site's "action area" as defined in Appendix A of EPA permit.

The construction site's discharges and discharge-related activities were already addressed in another operator's valid certification of eligibility for your action area under eligibility Criterion A, C, D, E, or F and there is no reason to believe that federally-listed species or federally-designated critical habitat not considered in the prior certification may be present or located in the "action area". To certify your eligibility under this Criterion, there must be no lapse ofNPDES permit coverage in the other operator's certification.

By certifying eligibility under this Criterion, you agree to comply with any effluent limitations or conditions upon which the other operator's certification was based. You must include in your NOI the tracking number from the other operator's notification of authorization under this permit. If your certification is based on another operator's certification under Criterion C, you must provide EPA with the relevant supporting information required of existing dischargers in Criterion C in the EPA NOI form.

Federally-listed threatened or endangered species or their designated critical habitat(s) are likely to occur in or near your site's "action area," and your site's discharges and discharge-related activities are not likely to adversely affect listed threatened or endangered species or critical habitat. This determination may include consideration of any stormwater controls and/or management practices you will adopt to ensure that your discharges and discharge-related activities are not likely to adversely affect listed species and critical habitat. To make this certification, you must include the following in your NOi: 1) any federally listed species and/or designated habitat located in your "action area"; and 2) the distance between your site and the listed species or designated critical habitat (in miles). You must also include a copy of your site map with the

NOL

Coordination between you and the Services has been concluded. The coordination must have addressed the effects of your site's discharges and discharge-related activities on federally-listed threatened or endangered species and federally-designated critical habitat, and must have resulted in a written concurrence from the relevant Service(s) that your site's discharges and discharge-related activities are not likely to adversely affect listed species or critical habitat. You must include copies of the

[16]

Criterion E.

Criterion F.

c01Tespondence between yourself and the Services in your SWPPP and

NOL

Consultation between a Federal Agency and the U.S. Fish and Wildlife Service and/or the National Marine Fisheries Service under section 7 of the ESA has been concluded. The consultation must have addressed the effects of the construction site's discharges and discharge-related activities on federally-listed threatened or endangered species and federally designated critical habitat. The result of this consultation must be either:

L a biological opinion that concludes that the action in question (taking into account the effects of your site's discharges and discharge-related activities) is not likely to jeopardize the continued existence of listed species, nor the destruction or adverse modification of critical habitat; or

11. written concurrence from the applicable Service(s) with a finding that the site's discharges and discharge-related activities are not likely to adversely affect federally-listed species or federally-designated habitat.

You must include copies of the correspondence between yourself and the Services in your SWPPP and NOL

Your construction activities are authorized through the issuance of a permit under section 10 of the ESA, and this authorization addresses the effects of the site's discharges and discharge-related activities on federally listed species and federally-designated critical habitat. You must include copies of the correspondence between yourself and the Services in your SWPPP and NOL

Section 7: Erosion and Sediment Controls

Control measures at the construction site are selected, installed, implemented, and maintained to minimize pollutants in the discharge as necessary to meet applicable water quality standards.

The objectives of this SWPPP include:

• Stabilize the site as soon as possible (targeting the preparation and implementation of erosion and sediment controls to get the site to final grade, and either permanently or temporarily stabilize all bare soil areas as soon as possible).

• Perimeter controls will be installed before ground disturbing activities are initiated.

• Perimeter protection will remain in place until final stabilization has been achieved.

• Slopes and channels will be protected by conveying concentrated stormwater runoff around the top of slopes and stabilize slopes as soon as possible. A void disturbing natural channels and the vegetation along natural channels as much as possible.

• Divert stormwater coming on to the site by conveying it safely around, through, or under the work area. (Divert the clean water, trap the dirty water.)

• Protect receiving waters and other environmentally sensitive waters or areas adjacent to the site.

• Follow pollution prevention measures by providing proper containers for waste and garbage at the site. Store hazardous materials and chemicals so that they are not exposed to stormwater.

• Minimize the area and duration of exposed soils. Clear only land that will be under construction in the near future.

7.1 Natural Buffers or Equivalent Sediment Controls (Required for EPA CGP states only - ID, WA)

This section only applies if a surface water is located within 50 feet of the project's earth disturbing activities.

Are there any surface waters within 50 feet of the project's earth disturbances? Yes

If No, then no further documentation is required for the SWPPP.

NOTE: Reference EPA CGP appendix G for buffer guidance.

If Yes, check which natural buffer compliance alternative is used at the project site:

D The project will provide and maintain a 50-foot wide undisturbed natural buffer.

The location and width of natural buffers are shown on the Erosion and Sediment Control Plan sheets in TAB 6.

[19]

D The project will provide and maintain an undisturbed natural buffer that is less than 50 feet in width and is supplemented by additional erosion and sediment controls, which in combination achieves the sediment load reduction equivalent to a 50-foot undisturbed natural buff er.

The location of natural buffers are shown on the Erosion and Sediment Control Plan sheets in TAB 6.

Document the method used to determine that the above combination of natural buffer and sediment and erosion controls equal the estimated sediment removal capacity of a 50-foot undisturbed natural buffer: Click here to enter text.

IZl It is infeasible to provide and maintain an undisturbed natural buffer of any size, therefore, the project will implement erosion and sediment controls that achieve the sediment load reduction equivalent to a 50-foot undisturbed natural buffer.

Insert rationale for concluding that providing and maintaining a natural buffer of any size is infeasible: The project includes bridge replacement and the existing bridge is directly adjacent to Fall Creek with no existing natural buffer. The project also includes a temporary bypass road around the bridge, and includes temporary culverts. A natural buffer will be maintained where possible.

Insert description of erosion and sediment controls to be used to achieve the sediment load reduction equivalent to a 50-foot undisturbed natural buffer: Silt fence at perimeters of work areas; fiber rolls placed along contours of slopes; tackifier placed on temporarily disturbed slopes; mulch placed on final slopes

D The project qualifies for one of the exceptions in EPA COP Part 2.1.2.1.e

D For a "linear project", site constraints (e.g. limited right of way) make it infeasible for the project to meet any of the COP part 2.1.2.1.a compliance alternatives.

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, final 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.

Section 8: Operational Controls/Good Housekeeping Measures

8.1 Hazardous Spill Plan

Spills and potential stormwater contamination will be controlled to reduce the chance of spills, stop the source of spills, contain and clean up spills, and dispose of materials contaminated by spills.

Spill prevention and response actions are outlined in the Hazardous Spill Plan or Spill Prevention, Control, and Countermeasure Plan (SPCC) whichever is applicable, TAB 15.

Construction sites may be subject to 40 CFR Part 112 regulations that require the preparation and implementation of a Spill Prevention, Control and Countermeasure Plan if the facility is a non transportation-related facility that: has a total storage capacity greater than 1,320 gallons or a completely buried storage capacity greater than 42,000 gallons and could reasonably be expected to discharge oil in quantities that may be harmful to navigable waters of the United States and adjoining shorelines. See EPA website: http://www.epa.gov/OEM/content/spcc/index.htm

Implementation: Prior to construction activities and throughout construction.

8.2 Spills/Releases in Excess of Reportable Quantities

This permit does not provide authorization to discharge hazardous substances or oil resulting from an on-site spill. This permit does not provide relief from the federal reporting requirements of 40 CFR Part 110, 40 CFR Part 117 and 40 CFR Part 302 relating to spills or other releases of oils or hazardous substances.

For a release containing a hazardous substance or oil in an amount equal to or in excess of a reportable quantity established under either 40 CFR Part 110, 40 CFR Part 117 or 40 CFR Part 302, occurs during a 24-hour period:

• Notice will be provided to the National Response Center (800-424-8802) in accordance with the requirements of 40 CFR Part 110, 40 CFR Part 117 and 40 CFR Part 3 02 as soon as site staff have knowledge of the discharge; and written notice will be provided within 7 calendar days of knowledge of the release, provide a description of the release, the circumstances leading to the release, and the date of a release.

• Measures to prevent the reoccurrence of such releases will be implemented.
