For the Melody Ranch Improvement and Service District, Water Valve Repair Project

Teton County, Wyoming

The Department of Environmental Quality/Water Quality Division (DEQ) has conducted a review of the proposed water valve repair project in accordance with EPA and State of Wyoming procedures for implementing the State Environmental Review Process.  DEQ has determined that this water valve repair 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.

This project will improve the Melody Ranch municipal water system with reliable isolation valves. The project will result in improved reliability of water supply, improved system operation, a reduction of water lost to leakage, and a reduced potential for damaging water main breaks.  Based on current cost estimates, the Melody Ranch Improvement and Service District plans to borrow $330,000 from the Wyoming Drinking Water State Revolving Loan Fund administered by the Wyoming Office of State Lands and Investments. Increased user fees will repay the loan. The average rate increase is estimated to be $3.60/month per user to repay the loan.  Loan terms will be 2.5% interest rate and 20 years.

The Melody Ranch ISD 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 involves repairs to existing infrastructure located with existing roads and easements. This project will be completely constructed in previously disturbed ground, specifically ground disturbed by the construction of the Melody Ranch water and sanitary sewer systems, power, gas, and communication facilities, and the road and pathway infrastructure.  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.  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.
