CATEGORICAL EXCLUSION DETERMINATION For the City of Laramie Wastewater Treatment Plant Upgrades Project, Albany County, Wyoming. The Department of Environmental Quality/Water Quality Division (DEQ) has conducted a review of the proposed Laramie Wastewater Treatment Plant Upgrades 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 Laramie Wastewater Treatment Plant Upgrades Project includes the design and construction of a new building, purchase of new blower equipment and full plant generators to be housed in the new building. Based on current cost estimates, the City of Laramie plans to borrow $9,500,000 from the Wyoming Clean Water State Revolving Loan Fund administered by the Wyoming Office of State Lands and Investments. Current wastewater user fees will repay the loan and do not require an increase in rates at this time. Loan terms will be 2.5% interest rate and 30 years. The City of Laramie 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 construction of new infrastructure will occur on the same property of existing infrastructure. This project will be completely constructed in previously disturbed ground, specifically ground disturbed by daily operations of the Laramie Wastewater Treatment Plant. 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 Laramie, Albany 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.
