CATEGORICAL EXCLUSION DETERMINATION

For the City of Laramie Landfill Stage 2 Expansion Project located at 162 Roger Canyon Road, Laramie, Albany County, Wyoming.

The Department of Environmental Quality/Water Quality Division (DEQ) has conducted a review of the proposed Landfill Stage 2 Expansion 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 Landfill Stage 2 Expansion project includes the construction of landfill cells 1b, 2a, and 2b. When complete, the project will provide an additional 15 years of landfill capacity. The construction of the next three cells is being pursued concurrently to realize economies of scale and reduce costs associated with multiple, consecutive projects. The cells will be lined with a geosynthetic liner and will include a leachate system that drains to the existing leachate collection system. In addition, the City is proposing a Water Balance Closure Cover, which reduces construction costs by nearly half and will allow for evapotranspiration.

The City of Laramie intends to use funds from the Wyoming Clean Water State Revolving Loan Fund administered by the Wyoming Office of State Lands and Investments. Based on current estimates, the City of Laramie plans to borrow $5,000,000 from the Wyoming Clean Water State Revolving Loan Fund. Current user fees will repay the loan and do not require an increase in rates at this time. Loan terms will be 2.5% over 15 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 this project utilizes already existing infrastructure on the site. This project will be completely constructed in previously disturbed ground, specifically ground disturbed by previous landfilling operations such as waste cells, buildings and other existing improvements on the Laramie Landfill site. 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 Department of Environmental Quality Office and is available for public scrutiny upon request. Comments concerning this decision may be addressed to Stan Miller, SRF Project Engineer, Department of Environmental Quality 200 West 17th Street, Suite 200, Cheyenne, WY 82002, telephone (307) 777-6371, email Stanley.miller@wyo.gov
