CATEGORICAL EXCLUSION DETERMINATION

For the SOUTH END WATER USERS IMPROVEMENT & SERVICE DISTRICT 

CONTROL BUILDING UPGRADE AND LOOP PROJECT,

BIG HORN County, Wyoming

The Department of Environmental Quality/Water Quality Division (DEQ) has conducted a review of the proposed SOUTH END WATER USERS IMPROVEMENT & SERVICE DISTRICT CONTROL BUILDING UPGRADE AND LOOP 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. 

This project consists of replacing the current underground vault that houses the controls for receiving water from the Town of Cowley.  This vault has reached its design life and allows ground water to enter the vault causing a potential unsafe environment for the controls and personnel who maintain them.  A new control building will be constructed above ground near the current vault location.  This building will be safer for the district.  The project also consists of connecting a water line from the current line around the old cannery to the Town of Cowley’s water line near sage creek.  This connection will help create a loop in the system providing safer conditions for the water and increasing pressure to the end of the current line.  A new control building will also be built in this location to house the controls necessary to receive water at this end of the system.  The estimated cost of the project is $505,200.00.  The project will be funded from a pending grant from Wyoming State Loan and Investment Board’s Mineral Royalty Grant program for $252,600.00, and a loan from Drinking Water State Revolving Fund for $252,600.00.  Repayment of the SRF loan will be from the revenue generated from the sale of water in the system and the District’s reserves.  It is anticipated that rates will be increased to pay for the loan. 

The SOUTH END WATER USERS IMPROVEMENT & SERVICE DISTRICT 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 CONSISTS OF MINOR UPGRADES AND EXPANSIONS TO EXISTING INFASTRUCTURE. This project will be completely constructed in previously disturbed ground, specifically ground disturbed by A PREVIOUSLY INSTALLED ROADWAY AND 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 SOUTH END WATER USERS IMPROVEMENT & SERVICE DISTRICT, BIG HORN 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 Stanley Miller, SRF Project Engineer, DEQ Cheyenne Office, 200 West 17th St., Suite 200, Cheyenne, WY  82002, telephone (307) 777-6371, email stanley.miller@wyo.gov
