Categorical Exclusion Determination, Evansville, WY, Evansville Emergency Connection Project

The Department of Environmental Quality/Water Quality Division (DEQ) has conducted a review of the proposed Evansville Emergency Connection 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 Evansville Emergency Connection Project consists of a connection to the City of Casper's water system, a chlorination building and miscellaneous components to provide a supply of water to the Town of Evansville's water distribution system in the case of an emergency where the Town of Evansville is not able to produce water at their Water Treatment Plant.


Based on current cost estimates, the Town of Evansville plans to borrow $478,415 from the Wyoming Drinking Water State Revolving Loan Fund administered by the Wyoming Office of State Lands and Investments. Existing user fees will repay the loan. There is no expected rate increase to repay the loan. Loan terms will be 0.75% interest rate and 20 years.


The Town of Evansville is aware of and accepts the fact that they will be responsible for any required mitigative actions associated with the project, including but not limited to storm water runoff, erosion control, archeological/historic artifacts, and air quality concerns. These actions will be part of the standard State Revolving Funds Program contract conditions. DEQ is granting an exclusion because the project involves minor upgrades and minor ancillary facilities adjacent to and on the same property as existing facilities. This project will be completely constructed in previously disturbed ground, Storage Tank. 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 Town of Evansville, Natrona County, Wyoming.


The determination shall become effective upon distribution by the Department and may be re-evaluated and the determination changed at any time that adverse information is made available. The documentation to support this decision will be on file in the DEQ Cheyenne Office and is available for public review upon request. To request a copy of the categorical exclusion, contact:
