Supporting Documentation

Provide documentation for the applicable eligibility criterion you select in Appendix D, as follows:

For criterion A, indicate the basis for your determination that 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 the permit). Check the applicable source of information you relied upon:

Specific communication with staff of the U.S. Fish & Wildlife Service or National Marine

Fisheries Service. INSERT DATE OF COMMUNICATION AND WHO YOU SPOKE WITH

For criterion B, provide the Tracking Number from the other operator’s notification of permit authorization: INSERT AUTHORIZATION TRACKING NUMBER FROM OTHER OPERATOR'S NOTIFICATION

LETTER/EMAIL

Provide a brief summary of the basis used by the other operator for selecting criterion A, B, C, D, E, or F: INSERT TEXT HERE

For criterion C, provide the following information:

▪ INSERT LIST OF FEDERALLY-LISTED SPECIES OR FEDERALLY-DESIGNATED CRITICAL HABITAT LOCATED IN

YOUR ACTION AREA

▪ INSERT DISTANCE BETWEEN YOUR SITE AND THE LISTED SPECIES OR CRITICAL HABITAT (in miles)

Also, provide a brief summary of the basis used for determining that your site’s discharges and discharge-related activities are not likely to adversely affect listed species or critical habitat: INSERT TEXT HERE

For criterion D, E, or F, attach copies of any letters or other communication between you and the U.S. Fish & Wildlife Service or National Marine Fisheries Service concluding consultation or coordination activities. INSERT COPIES OF LETTERS OR OTHER COMMUNICATIONS HERE

5. Historic Preservation:

Step 1

Do you plan on installing any of the following stormwater controls at your site? Check all that apply below, and proceed to Appendix E, Step 2.

Dike

Berm

Catch Basin

Pond

Stormwater Conveyance Channel (e.g., ditch, trench, perimeter drain, swale, etc.)

Culvert

Other type of ground-disturbing stormwater control: Four sub-surface seepage beds

(Note: If you will not be installing any ground-disturbing stormwater controls, no further documentation is required for

Section 3.2 of the Template.)

Step 2

If you answered yes in Step 1, have prior surveys or evaluations conducted on the site already determined that historic properties do not exist, or that prior disturbances at the site have precluded the existence of historic properties? YES NO

▪ If yes, no further documentation is required for Section 3.2 of the Template.

▪ If no, proceed to Appendix E, Step 3.

Step 3

If you answered no in Step 2, have you determined that your installation of subsurface earth-disturbing stormwater controls will have no effect on historic properties?

YES NO

If yes, provide documentation of the basis for your determination. National Register of Historic Places

(NRHP) database (NPS 2024) for Ada County, Idaho

If no, proceed to Appendix E, Step 4.

Step 4

If you answered no in Step 3, did the State Historic Preservation Officer (SHPO), Tribal Historic

Preservation Office (THPO), or other tribal representative (whichever applies) respond to you within 15 calendar days to indicate whether the subsurface earth disturbances caused by the installation of stormwater controls affect historic properties? YES NO

If no, no further documentation is required for Section 3.2 of the Template.

If yes, describe the nature of their response:

Written indication that adverse effects to historic properties from the installation of stormwater controls can be mitigated by agreed upon actions. INSERT COPIES OF LETTERS, EMAILS, OR OTHER COMMUNICATION BETWEEN YOU AND THE APPLICABLE SHPO, THPO, OR OTHER TRIBAL

REPRESENTATIVE
