The Department of Environmental Quality/Water Quality Division (DEQ) has conducted a review of the proposed 2025 Water and Sewer Improvements 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 proposed project will include rehabilitation and replacement of existing sewer collection and water distribution facilities within the Town of Sinclair. The scope of work will include rehabilitation and/or replacement of three blocks of existing damaged and deteriorated vitrified clay pipe sewer main. The project will also include removal and replacement of three or four blocks of existing cast-iron watermain in the same vicinity. Additionally, the project will include replacement of deteriorated concrete curb and asphalt pavement within the project area. The project is necessary to reduce ongoing operating and maintenance costs and to mitigate inflow, infiltration, and cross-contamination risks.
The estimated cost for the 2025 Water and Sewer Improvements Project is $2,800,000. The Town of Sinclair has requested a Wyoming Clean Water State Revolving Loan Fund in the amount of $1,000,000. Principal forgiveness in the amount of $500,000 (50%) has been requested. Loan terms will be 1.5% interest rate and the term of the loan will be 20 years. The Town of Sinclair has allocated $1,800,000 of Town reserve funds to be used to fund the project. User rate fees will not be increased as a result of this project.
The Town of Sinclair 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. No significant environmental impacts that require mitigation have been identified.
DEQ is granting an exclusion because the project includes modifications to an existing system and is being constructed in previously disturbed ground, specifically ground previously disturbed by the installation of the existing water and sewer lines and roads. 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 Sinclair, Carbon County, Wyoming.
