For the Town of Star Valley Ranch, Water Improvement Project - 2021,
Lincoln County, Wyoming

The Department of Environmental Quality/Water Quality Division (DEQ) has conducted a review of the proposed Water Improvement Project – 2021 project in accordance with EPA and State of Wyoming procedures for implementing the State Environmental Review Process. DEQ has determined that this project is eligible for a categorical exclusion. Accordingly, DEQ is exempting the project from further substantive environmental review requirements under the State Environmental Review Process. Neither and Environmental Assessment/Finding of No Significant Impact nor an Environmental Impact Statement/Record of Decision will be required for the proposed action. The following is a brief description of the situation and the proposed action and a brief statement of how the action meets the criteria for a categorical exclusion.

The Water Improvement Project – 2021 will replace approximately 24,000 lineal feet of PVC pipeline that is undersized and is failing due to faulty original construction and aging materials. The total project cost is approximately $4,895,800.00. Proposed funding for the project consists of a Mineral Royalties Grant of $1,615,614.00, and a Drinking Water State Revolving Fund Loan of $3,280,186.00. The terms of Proposed SRF loan is 20 years at 2.5% interest with an anticipated 25% principal forgiveness. With the 25% principal forgiveness the anticipated loan amount is $2,460,139.50. There is a 0.5% Loan Origination Fee. Loan costs will be repaid by water user fees.

The Town of Star Valley Ranch is aware of and accepts the fact that they will be responsible for any required mitigative actions associated with and including storm water runoff, erosion control, archeological/historic artifacts, and air quality concerns. These will be part of the standard State Revolving Funds Program contract conditions.

DEQ is granting an exclusion because this project replaces existing infrastructure. This project will be completely constructed in previously disturbed ground, specifically ground disturbed by previously installed waterline. DEQ has determined that exempting the proposed project from further review under the State Environmental Review Process will not result in adverse impacts to the population or the area of the Town of Star Valley Ranch, Lincoln County, Wyoming.

The documentation to support this decision will be on file in the DEQ Cheyenne Office and is available for public scrutiny upon request. Comments concerning this decision may be addressed to Stan Miller, SRF Project Engineer, Department of Environmental Quality, 200 W. 17th St. Suite 200, Cheyenne, WY 82002, Tel (307) 777-6371, FAX (307) 635-1784, email:
