Construction Stormwater Pollution Prevention Plan Template

To be used for IPDES permit requirements: This Template has been adapted from the EPA’s SWPPP Template. References and guidance language has been revised/updated, but if there is any conflict you must follow the IPDES permit and requirements as well as the SCRs.

Instructions for Using the SWPPP Template

Each section of the SWPPP Template includes instructions and space for your project and site information. Read the instructions for each section before you complete that section. Specific instructions on what information to include is indicated in each text field in blue text.

Click on the blue text and the instructions will disappear once you start typing.

The SWPPP Template is an editable document file so that you can easily add tables and additional text and delete unneeded or non-applicable fields. Note that some sections may require only a brief description while others may require several pages of explanation.

The following tips for using this template will help ensure that you meet the minimum permit requirements:

• Read the IPDES 2022 CGP thoroughly before you begin preparation of your SWPPP to ensure that you have a working understanding of the permit’s underlying requirements.

• Complete the SWPPP prior to submitting your NOI for permit coverage. This is required in Parts 1.4 and 7.1.

• If there is more than one construction operator for your project, consider coordinating development of your SWPPP with the other operators.

• Once DEQ has provided your site with coverage under the CGP, include your NOI, your authorization email, and a copy of the CGP as attachments to the SWPPP.

In the event of a conflict between the SWPPP Template and any corresponding provision of the 2022 CGP, you must abide by the requirements in the permit.

2.3 Nature of the Construction Activities

General Description of Project Provide a general description of the nature of your construction activities, including the age or dates of past renovations for structures that are undergoing demolition:

The proposed Clark County project consists of grading, drainage improvements, bridge structures, soft spot repair, aggregate base addition, culvert replacement, and asphalt surface course for the Forest Highway ID‐65 and STC 6805 (Yale‐Kilgore Road) from MP 9.0 to MP 16.9 (7.9 miles).

The proposed Fremont County project consists of drainage improvements, shoulder repair, pavement patching, existing pavement pulverizing or reclamation, and asphalt surface course of the Yale-Kilgore Road from MP 16.9 to MP 30.8 (13.9 miles).

The total length of the combined projects is approximately 21.8 miles. Both projects will widen the existing traveled way from 22’‐26’ to a consistent, 28'-wide asphalt overlay on a pulverized base.

From MP 26.25 to MP 30.55 (3.7 miles of the Fremont length), a gravel-surfaced, separated ATV and snowmobile trail would be constructed along the south side of the road, separate from the roadway. The trail design will include a 10‐foot-wide travel way, with added clearing width totaling 16 feet, to accommodate a snow grooming machine for winter trail maintenance.

SECTION 3: DOCUMENTATION OF COMPLIANCE WITH OTHER FEDERAL REQUIREMENTS

3.1 Endangered Species Protection

Eligibility Criterion Following the process outlined in Appendix C, under which criterion are you eligible for coverage under this permit?

☐ Criterion A: No ESA-listed species and/or designated critical habitat present in action area. Using the process outlined in Appendix C of the CGP, you certify that ESA-listed species and designated critical habitat(s) under the jurisdiction of the USFWS or NMFS are not likely to occur in your site’s “action area” as defined in Appendix A of the CGP.

Please Note: NMFS’ jurisdiction includes ESA-listed marine and estuarine species that spawn in inland rivers.

☐ Check to confirm you have provided documentation in your SWPPP (Note: reliance on State resources is not acceptable; see CGP Appendix C).

Documentation: Insert Text Here

Using the instructions in Appendix C of the permit, determine which criterion listed below (A-F) applies with respect to the protection of endangered species.

To make this determination, you must use information from BOTH the National Marine Fisheries Service (NMFS) and U.S. Fish and Wildlife Service (USFWS).

Both the NMFS and USFWS maintain lists of Endangered Species Act-listed (ESA-listed) species and designated critical habitat. Operators must consult both when determining their eligibility.

― Check only 1 box, include the required information, and provide a sound basis for supporting the criterion selected. Select the most conservative criterion that applies.

― Copies of the ESA compliance documentation should be placed in Tab 16 of the

SWPPP.

Eligibility Criterion Following the process outlined in Appendix C, under which criterion are you eligible for coverage under this permit?

☐ Criterion B: Eligibility requirements met by another operator under the 2022 CGP. 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 of the 2022 CGP and you have confirmed that no additional ESA-listed species and/or designated critical habitat under the jurisdiction of USFWS and/or NMFS not considered in the that certification may be present or located in the “action area.” To certify your eligibility under this criterion, there must be no lapse of NPDES permit coverage in the other CGP operator’s certification. By certifying eligibility under this criterion, you agree to comply with any conditions upon which the other CGP operator's certification was based. You must include in your NOI the IPDES ID from the other 2022 CGP operator’s notification of authorization under this permit and list any measures that you must comply with. If your certification is based on another 2022 CGP operator’s certification under criterion C, you must provide the relevant supporting information required of existing dischargers in Criterion C in your NOI form.

☐ Check to confirm you have provided documentation in your SWPPP.

Documentation: Insert Text Here

☐ Criterion C: Discharges not likely to adversely affect ESA-listed species and/or designated critical habitat. ESA-listed species and/or designated critical habitat(s) under the jurisdiction of the USFWS and/or NMFS are likely to occur in or near your site’s “action area,” and you certify to DEQ that your site’s discharges and discharge-related activities are not likely to adversely affect ESA-listed threatened or endangered species and/or designated critical habitat. This certification 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 ESA-listed species and/or designated critical habitat. To certify your eligibility under this criterion, indicate 1) the ESA-listed species and/or designated habitat located in your “action area” using the process outlined in Appendix C of this permit; 2) the distance between the site and the listed species and/or designated critical habitat in the action area (in miles); and 3) a rationale describing specifically how adverse effects to ESA-listed species will be avoided from the discharges and discharge-related activities. You must include a copy of your site map from your SWPPP showing the upland and in-water extent of your “action area” with your NOI.

Attaching: 1) the species list with the action area used to obtain the list; 2) aerial images of the site; and 3) a copy of the SWPPP to the NOI is helpful to EPA, USFWS, and NMFS in confirming eligibility under this criterion

☐ Check to confirm you have provided documentation in your SWPPP.

SECTION 4: EROSION AND SEDIMENT CONTROLS AND DEWATERING PRACTICES

4.1 Natural Buffers or Equivalent Sediment Controls

Buffer Compliance Alternatives Are there any receiving waters within 50 feet of your project’s earth disturbances? ☐ YES ☐ NO

(Note: If no, no further documentation is required for Section 4.1 in the SWPPP Template.

Continue to Section 4.2.)

Check the compliance alternative that you have chosen:

☐ (i) I will provide and maintain a 50-foot undisturbed natural buffer.

(Note 1: You must show the 50-foot boundary line of the natural buffer on your site map.)

(Note 2: You must show on your site map how all discharges from your construction disturbances through the natural buffer area will first be treated by the site’s erosion and sediment controls. Also, show on the site map any velocity dissipation devices used to prevent erosion within the natural buffer area.)

General Instructions (See CGP Parts 2.2 and 7.2.6):

― Describe the erosion and sediment controls that will be implemented at your site to meet the requirements of CGP Part 2.2.

― Describe any applicable stormwater control design specifications (including references to any manufacturer specifications and/or erosion and sediment control manuals/ordinances relied upon).

― Describe any routine stormwater control maintenance specifications.

― Describe the projected schedule for stormwater control installation/implementation.

Instructions (see CGP Parts 2.2.1 and 7.2.6.b.i, and Appendix D):

This section only applies to you if discharge to a receiving water is located within 50 feet of your site’s earth disturbances. If this is the case, consult CGP Part 2.2.1 and Appendix D for information on how to comply with the buffer requirements.

― Describe the compliance alternative (CGP Part 2.2.1.a.i, ii, or iii) that you will implement to meet the buffer requirements, and include any required documentation supporting the alternative selected. For alternative 3, also include why it is infeasible for you to provide and maintain an undisturbed natural buffer of any size. For “linear construction sites” where it is infeasible to implement alternative 1, 2, or 3, also include a description of any buffer width retained and/or supplemental erosion and sediment controls installed. The compliance alternative selected must be maintained throughout the duration of permit coverage. However, if you select a different compliance alternative during your period of permit coverage, you must modify your SWPPP to reflect this change.

― If you qualify for one of the exceptions in CGP Part 2.2.1.b, include documentation related to your qualification for such exceptions.

Yale-Kilgore Road, MP 16.9 to 30.3: ID FREMONT 6805(1)
