CATEGORICAL EXCLUSION DETERMINATION

For the TOWN OF COWLEY WATER TANK PROJECT,

BIG HORN County, Wyoming

The Department of Environmental Quality/Water Quality Division (DEQ) has conducted a review of the proposed COWLEY WATER TANK 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 construction of a new 500,000 gallon water tank and installing 2,400 feet of 10 inch PVC water line in the Town of Cowley, WY.  The project also includes the reconstruction of a chlorination building with chlorination equipment necessary to treat the Town’s water.  The estimated cost of the project is $4,710,000.00.  The project will be funded from a grant from Wyoming Water Development for $3,155,700.00, a loan from Drinking Water State Revolving Fund for $1,379,300.00, a grant from the Mineral Royalty of $75,000.00 and $100,000.00 from Town Reserves.  Repayment of the SRF loan will be from the revenue generated from the sale of water in the system.  It is not anticipated that rates will be increased to pay for the loan. 

The TOWN OF COWLEY 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 REPLACES EXISTING INFASTRUCTURE ON THE SAME PROPERTY. This project will be completely constructed in previously disturbed ground, specifically ground disturbed by A PREVIOUSLY INSTALLED WATERLINE, STORAGE TANK, AND CHLORINATION BUILDING.  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 COWLEY, 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
