6.1 Endangered Species Protection

Under which criterion is project eligible for Endangered Species coverage under the NPDES permit (EPA)?

~A DB De Dn OE

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

[14]

Criterion E.

Criterion F.

correspondence between yourself and the Services in your ESCP 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:

i. 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

IL 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 ESCP and NOi.

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 ESCP and NOi.

Support Documentation for Endangered Species criterion eligibility is filed in TAB 16.

6.2 Historic Preservation

1. Will the project involve installation of any of the following stormwater controls that entail subsurface earth disturbance? Choose an item.

D Dike

D Berm rg:i Catch Basin

D Pond rg:i Ditch, trench, swale, perimeter drain, etc.

rg:i Culvert rg:i Other ground-disturbing stormwater control: Restroom building subexcavation, Parking area subexcavation, Vault Toilet subexcavation, and Waterline and Accessory Installation

If the project involves no installation of earth-disturbing storm water controls, then no further historic preservation screening is necessary (for NPDES permitting purposes).

2. If answer to step 1 is Yes, have professional surveys or evaluations determined that historic properties do not exist (or have prior disturbances at the site precluded the existence of historic properties)? Yes

[15]

Provide documentation for the basis of this determination: Project falls under the USFS Programmatic Agreement. USFS is Section 106 Federal Lead Agency.

3. If answer to step 2 is No, have professional surveys or evaluations determined that installation of stormwater controls will have no effect on historic properties? Choose an item.

Provide documentation for the basis of this determination. Click here to enter text.

4. Has the State Historic Preservation Officer (SHPO), Tribal Historic Preservation Office (THPO) or other tribal representative concurred with the determinations of effects on historic properties? Yes

Provide the nature of their response: Project is covered under the USFS Programmatic Agreement; Undertaking meets the criteria listed in Appendix C (Exempt/Non-undertaking).

6.3 Safe Drinking Water Act Underground Injection Control Requirements

Will the project plan install any of the following controls? No

Check all that apply:

D Infiltration trenches (if stormwater is directed to any bored, drilled, driven shaft or dug hole that is deeper than is widest surface dimension, or has a subsurface fluid distribution system)

D Commercially manufactured pre-cast or pre-built proprietary subsurface detention vaults, chambers, or other devices designed to capture and infiltrate stormwater flow.

D Drywells, seepage pits, or improved sinkholes (if stormwater is directed to any bored, drilled, driven shaft or dug hole that is deeper than its widest surface dimension, or has a subsurface fluid distribution system)

If yes, provide documentation of communications with the EPA or applicable State agency.

Contractor to review, revise and edit as needed.

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 ESCP 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 corning 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

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 ESCP.

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.

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 is shown on the Erosion and Sediment Control Plan sheets in TAB 6.

[8J 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: A natural buffer to the greatest extent feasible will be established where feasible, however, there are areas where work is proposed immediately adjacent to wetlands, the tributary to Detroit Lake and Detroit Lake itself. The project was designed to avoid these resources directly, but it was not possible to establish buffer areas due to the limited space between the resources and existing roadways.

[8J The project qualifies for one of the exceptions in EPA CGP Part 2.1.2.1.e

[8J For a "linear project", site constraints (e.g. limited right of way) make it infeasible for the project to meet any of the CGP part 2.1.2. l .a compliance alternatives.

D Other exception (state type): Click here to enter text.

Document why it is infeasible to meet one of the buffer compliance alternatives: The existing roadway (Detroit Ave) is constructed at the outer boundary of Forest Service property so the widening is taking place closer to the wetland to avoid private property.

The design widths were reduced to avoid direct impacts to the wetlands and waterway itself.

Insert description of erosion and sediment controls to be used to achieve the sediment load reduction equivalent to a 50-foot undisturbed natural buffer: Orange mesh fence will be installed at the edge of the wetland to alert the contractor of the sensitive resource.

7.2 Perimeter Controls

All Perimeter Sediment Controls will be installed prior to ground disturbing activities taking place. There will be no clearing or grubbing outside the physical clearance limits.

Locations and design specifications of BMPs are shown on the erosion and sediment control plan sheets in TAB 6.

Control measure: Fiber rolls

Implementation: All fiber rolls will be installed prior to any ground disturbing activities. Please also refer to project schedule, contract, and plan set (Erosion Control section).

Maintenance requirements: Sediment will be removed from fiber roll perimeter controls before deposits reach 50% of the above ground height. It is the Contractor's responsibility to upgrade erosion control measures as necessary if the sediment controls are ineffective and turbid water is

[18] observed discharging from the site. Fiber rolls will not be removed until vegetation is established.

Control measure: Silt Fence

Implementation: The silt fence shall be installed before other land disturbing activities take place. Silt fence should be functional throughout the duration of construction and for a long enough duration following construction to allow disturbed areas to stabilize following revegetation and seeding. Please also refer to project schedule, contract, and plan set (Erosion Control section).

Maintenance requirements: Silt fences should be inspected periodically for damage (such as tearing by wind, animals, or equipment) and for sediment that has accumulated. Remove the sediment when it reaches one-half the height of the silt fence. In situations where access is available, machinery can be used. Otherwise, silt should be removed manually. The following are key elements to remember:

• The sediment deposits should be removed when heavy rain or high water is anticipated.

• The sediment deposits should be placed in an area where there is little danger of eros10n.

• The silt fence should not be removed until adequate vegetative growth ensures no further erosion of the slopes. Generally, the fabric is cut at ground level, the wire and posts are removed, then the sediment is spread, seeded, and protected (mulched) immediately.

Control measure: Temporary diversion channel (dike)

Implementation: Should be adequately compacted by earth-moving equipment to prevent failure.

To be implemented in accordance with schedule and contract along the North Trail alignment.

Please also refer to project plan set (Erosion Control section).

Maintenance: Dikes should be inspected after every rainfall event and at least once every two weeks, regardless of storm events. Attention should be paid to the outlet of the dike to ensure that diverted runoff is exiting the area as designed.

Add other measures as needed.

7.3 Sediment Track-Out

The following methods will be implemented to minimize off-site vehicle tracking of sediment onto paved surfaces. If sediment escapes the construction site, off-site accumulations of sediment will be removed at a frequency sufficient to minimize off-site impacts.

Locations and design specifications of BMPs are shown on the erosion and sediment control plan sheets in TAB 6.

7.4 Stockpiled Soil or Other Erodible Materials

Stockpile management includes measures to minimize surface erosion and sediment transport from soil stockpiles or other erodible materials.

Locate erodible stockpiles away from drainages including storm sewer inlets and culvert inlets.

Locations of stockpiles are not designated and are, therefore, not shown on the erosion and sediment control plan sheets in TAB 6. Should stockpiles be necessary, locations must remain within the permitted area of impact and as determined by the Contractor and PE.

D Not applicable to this project. Reason: Click here to enter text.

If applicable:

The following BMPs are applicable to:

IZl Storm Drain Inlets

IZl Culvert Inlets

Control measure: Storm drainage inlet protection structures

Implementation: Protect inlet structures, before and during active construction. Means must prevent discharge of turbid water downstream. The Contractor shall remove inlet protection at the end of the project without releasing captured sediment into the storm system. to not allow sediment plugging. Please also refer to project schedule, contract, and plan set (Erosion Control section).

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, 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.

Describe velocity dissipation and/or erosion control devices to be installed at stormwater conveyance channels (such as roadside ditches) and culvert outlets. Includes permanent and temporary devices (specify).

Velocity dissipation devices will be placed at discharge locations and along the length of any outfall channel to provide a non-erosive flow velocity from the structure to a water course so that the natural physical and biological characteristics and functions are maintained and protected (e.g., no significant changes in the hydrological regime of the receiving water).

Locations and design specifications of BMPs are shown on the erosion and sediment control plan sheets in TAB 6.

D Not applicable to this project.

Control measure: Check Dams

Implementation: Following ditch construction. Please also refer to project schedule, contract, and plan set (Erosion Control section).

Control measure: Temporary culvert (pipe slope drain)

Implementation: Immediately following the disturbance of the slope on which it rests and should not be removed until the disturbed slope has been permanently stabilized. In accordance with schedule and contract along the North Trail alignment. Please also refer to project schedule, contract, and plan set (Erosion Control section).

Maintenance: Inspected weekly and after every storm. Repairs are to be made immediately.

Inlets should be kept free of debris. Drains should remain securely fastened to the slope at all times.
