Public Notice: Cat Ex Publication Notice for City of Sheridan's Landfill Cell 10 Phase I Project

Categorical Exclusion Determination:
For the City of Sheridan, Wyoming
Sheridan Landfill Cell 10 Phase I Project
Sheridan County, Wyoming

The Wyoming Department of Environmental Quality/Water Quality Division (WDEQ) has conducted a review of the proposed Sheridan Landfill Cell 10 Phase I 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 will be constructed in phases. Phase I will be constructed in the existing compost area and atop the southern portion of T678, with an approximate airspace capacity of 764,000 cubic yards. Phase I of Cell 10 will be constructed and available for disposal of any excavated waste associated with the selected remedial corrective measure. Therefore, the cost of excavating and disposing of emplaced waste was evaluated based on Cell 10 airspace construction cost.

To fund this project, the City intends to use funds from a Wyoming Clean Water State Revolving Fund (CWSRF) loan. The City will present the preliminary design of the proposed project at the public meeting being held on December 15, 2022. The total cost of the project is estimated at $4,115,000. Of this total project cost, the City plans to obtain the loan with a 1.25% interest rate. Revenues from Solid Waste Enterprise Fund will repay the loan.

The City of Sheridan is aware of and accepts the fact that they will be responsible for any required mitigative actions associated with and including stormwater 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 is within the landfill boundary and in an area that has been previously disturbed. 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 Sheridan or Sheridan 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 Shawn King, SRF Project Manager, Department of Environmental Quality, 200 W. 17th St. Suite 200, Cheyenne, WY 82002. Tel.
