Public Notice: CATEGORICAL EXCLUSION DETERMINATION for the Skyline Improvement and Service District

The Department of Environmental Quality/Water Quality Division (DEQ) has conducted a review of the proposed Skyline ISD Water Supply and Storage System Improvements 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 project consists of the equipping of three wells with VFDs where operation of two wells can meet peak hour demand with the largest well out of service to meet DEQ regulations, meters on each well to meet SEO regulations, new electrical service and backup power to power the larger pumps, new control system to operate pumps, new transmission piping at hydropneumatic tank to allow operation of VFDs, repairs to the hydropneumatic tank and building, and a sodium hypochlorite disinfection system to comply with DEQ regulations. All of the work will be performed in already disturbed areas. Completion of the project is expected in late Fall of 2025. In light of current cost estimates, the District plans to borrow $955,000 from the Wyoming Drinking Water State Revolving Loan Fund administered by the Wyoming Office of State Lands and Investments. A special assessment will repay the loan. The assessment is estimated to be at maximum $618.05/lot/year to repay the loan, based on loan terms of 1.5% interest and 20 years.

The District has inspected and is familiar with the project area. The District has found no evidence and has 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 District is aware of and accepts responsibility 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 will be constructed on previously disturbed ground. 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 Skyline Ranch in 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.
