Wyoming Department of Environmental Quality
Public Notice: CATEGORICAL EXCLUSION DETERMINATION for the Town of Pinedale, Sublette County, Wyoming

The Department of Environmental Quality/Water Quality Division (DEQ) has conducted a review of the proposed Wastewater Treatment Facility Rehabilitation Phase 1 and Phase 2 Engineering 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 Wastewater Treatment Facility Rehabilitation Phase 1 and Phase 2 Engineering Project will remove and replace deteriorated anaerobic pond covers and the UV disinfection system which has reached the end of its useable life, upgrade the bulk septic receiving to further protect the treatment equipment and treatment train, and install an outlet diffuser to improve mixing discharge waters across Pine Creek. The Phase 2 Engineering portion of the project will include the engineering design of a secondary treatment upgrade to the Wastewater Treatment Facility pursuant to the findings of the Wastewater Treatment Master Plan to reduce discharge of ammonia and other discharge parameters regulated by the Town of Pinedale WYPDES permit with DEQ. It is anticipated that the work will be completed in 2025. Based on current cost estimates, the Town of Pinedale plans to borrow $1,895,350 from the Wyoming Clean Water State Revolving Loan Fund administered by the Wyoming Office of State Lands and Investments. Increased user fees and reserves from the sewer enterprise fund will repay the loan. The average rate increase is estimated to be $4.41 per month per user to repay the loan. Loan terms will be, at maximum, 1.5% interest rate and 30 years.

Town personnel have inspected and are familiar with the project area. Town personnel found no evidence and have no knowledge that the project area contains endangered/threatened species, suitable habitat for endangered/threatened species, migratory birds, eagles, jurisdictional waters of the United States, or prime agricultural lands. The Town is aware of and accepts responsibility 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 project will be constructed in previously disturbed ground, more specifically the wastewater treatment plant 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 Town of Pinedale in Sublette 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.
