For the Town of Moorcroft, Goshen Street Water Main Project

Crook County, Wyoming

The Department of Environmental Quality/Water Quality Division (DEQ) has conducted a review of the proposed Goshen Street Water Main 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. Recent water main repairs have been required in the Goshen Street area and replacing the entire water main would eliminate interruptions in service and the possibility for cross-contamination every time a repair is required. The project includes the replacement of water mains in the Goshen Street area, removing aging 6” water mains to 8 inch PVC and improve flows in the area. The project also includes removal and replacement of ACC pavement, concrete curb and gutter, and sidewalks affected by the project. The project is estimated to cost $2,430,000, with a requested DWSRF loan amount of $941,160 and CWSRF loan amount of $273,840. The requested term for the loans are 30 years at 2.5%, and will be repaid using the user fees investment fund. Each user is charged $18/month for the water investment fund and $17/month for the sewer investment fund.  

The Town of Moorcroft 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 in the same existing roadways as existing facilities.  The utility replacements are located on the same property as existing facilities. This project will be completely constructed in previously disturbed ground, specifically previously installed water and sewer mains and the road above the water and sewer mains. 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 Moorcroft and Crook County, Wyoming. 

The documentation to support this decision will be on file in the DEQ Casper Field Office and is available for public scrutiny upon request. Comments concerning this decision may be addressed to Brian Mark, Principal Engineer, DEQ/WQD, 200 West 17th Street, Cheyenne, WY 82002, telephone (307) 777-6371, email
