Categorical Exclusion Determination, Casper, WY, City Reservoir Replacement Project

The Department of Environmental Quality/Water Quality Division (DEQ) has conducted a review of the proposed City Reservoir Replacement 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 City of Casper is undergoing a project to replace the existing City Reservoir, which is at the end of its serviceable life. The total project cost is estimated at $15,607,572.50 and is anticipated to be funded by a State Revolving Fund Loan, Wyoming Water Development Commission Grant, and City of Casper Water Revenues. Repayment of the loan will be done utilizing funds collected through water sales to City of Casper customers. It is not anticipated that loan repayments will have an impact on planned water rate increases.
The City of Casper is aware of and accepts the fact that they will be responsible for any required mitigative actions associated with proper procedures for construction and demolition, including asbestos abatement, 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 work performed as part of this project is not anticipated to have significant environmental impacts. 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 City of Casper, and 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:
