2. Discharge Information

i. Does your project/site discharge stormwater into a Municipal Separate Storm Sewer

System (MS4)? Yes No

ii. Are there any surface waters that are located within 50 feet of your construction disturbances? Yes No

iii. Names of Receiving Waters:

Name(s) of the first surface water that receives stormwater directly from your site and/or from the MS4 (note: multiple rows provided where your site has more than one point of discharge that flows to different surface waters)

1. Fivemile Creek

2. Ridenbaugh Canal 3.

Is this surface water listed as “impaired”?

If you answered yes, then answer the following:

What pollutant(s) are causing the impairment?

Has a TMDL been completed?

Title of the TMDL document

Pollutant(s) for which there is a

TMDL

1. YES NO YES NO

iv. Describe the method(s) you used to determine whether or not your project/site discharges to an impaired water: The map query at the bottom of the page on the following link. EPA.GOV/NPDES/EPAS-STORMWATER-DISCHARGE-MAPPING-TOOLS

v. Are any of the surface waters to which you discharge designated by the state or tribal authority under its antidegradation policy as a Tier 2 (or Tier 2.5) water (water quality exceeds levels necessary to support propagation of fish, shellfish, and wildlife and recreation in and on the water) or as a Tier 3 water (Outstanding Natural Resource

Water)? (See Appendix F). Yes No If yes, name(s) of receiving water(s) and its designation (Tier 2, Tier 2.5 or Tier 3): N/A

3. Nature of the Construction Activity

i. Size of Construction Project: What is the size of the property (in acres), the total area expected to be disturbed by the construction activities (in acres), and the maximum area expected to be disturbed at any one time?

2.8 Acres

4. Endangered Species Protection:

i. Eligibility Criterion: ☐A ☐B ☒C ☐D ☐E

ii. Include documentation supporting your determination of eligibility.

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.

Publicly available species list.

Other source:

For criterion B, provide the Tracking Number from the other operator’s notification of permit authorization:

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

For criterion C, provide the following information:

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

YOUR ACTION AREA

• BIRDS – Yellow-billed Cuckoo (Threatened)

• INSECTS

o Monarch Butterfly (Candidate) o Physa Natricina (Endangered)

• NO CRITICAL HABITATS AT THE LOCATION

• POTENTIAL MIGRATORY BIRDS

o American White Pelican o Bald Eagle o California Gull o Cassin’s Finch o Evening Grosbeak o Lewis’s Woodpecker o Olive-Sided Flycatcher o Rufuous Hummingbird o Sage Thrasher

• Please visit page https://www.fws.gov/sites/default/files/documents/nationwide-standard-conservation-measures.pdf to assist in measures to reduce impacts to birds and their habitat.

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: There is no critical habitat within the vicinity of the project site. The listed species are not expected https://www.fws.gov/sites/default/files/documents/nationwide-standard-conservation-measures.pdf https://www.fws.gov/sites/default/files/documents/nationwide-standard-conservation-measures.pdf to be at or near the project site anytime during construction. Contractor is expected to use approved BMPs to mitigate and manage stormwater runoff during construction.

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.

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: N/A

(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.

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. N/A

No agreement has been reached regarding measures to mitigate effects to historic properties from the installation of stormwater controls. N/A
