For the Spring Creek Improvement and Service District’s Well No. 3 Project, Teton County, Wyoming

The Department of Environmental Quality/Water Quality Division (DEQ) has conducted a review of the proposed Spring Creek Improvement and Service District’s Well No. 3 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 an 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 SCISD’s Well No. 3 Project components consist of an 800 gpm well pump, check valve, flow meter, 460 LF of 12" pipe from the well to the valve vault, electrical conduit and wiring to a 125 HP pump motor, variable frequency drive with harmonic filters, controls to synchronize Well No. 3 with Well Nos. 1 and 2 and subsequent booster pumps, a chlorination system for Well No. 3, and site reclamation. The estimated cost of the improvements is $771,930.00. The SCISD’s Pre-Application was approved by the Wyoming State Loan and Investment Board on December 6, 2018 for a Drinking Water State Revolving Fund (DWSRF) loan in the amount of $600,000.00, utilizing $171,930.00 of reserves to fund the project. Increased tax assessments and user fees will repay the loan. The average rate increase is estimated to be approximately $24.00/month per user to repay the DWSRF loan, with terms of 2.5% interest and 30 years.

The SCISD has inspected and is familiar with the project area. They found no evidence and have no knowledge that the project area contains endangered/threatened species, suitable habitat for endangered/threatened species, migratory birds, eagles, jurisdictional waters of the United States, or prime agricultural lands. The SCISD 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 the project constructs facilities adjacent to and on the same property as existing facilities. All improvements will take place within previously disturbed areas, either alongside existing utilities or within access roads. 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 Teton 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.
