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 South Fremont Avenue Rehabilitation 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 purpose of this project is to replace old sewer and water mains under South Fremont Avenue and install a water main under the extension of South Sublette Avenue to create a water main loop.   There are no previously undisturbed areas being impacted for this project.

The project will replace approximately 600 feet of old, and undersized, water main and eliminate a dead end water main with the addition of a 500 foot water line, which will create a loop.   Approximately 700 feet of old, and undersized, vitrified clay sewer pipe will be removed and replaced with polyvinyl chloride pipe to improve flow and eliminate infiltration.  The water and sewer line construction under South Fremont Ave. is all replacement of existing infrastructure.  The work taking place along South Sublette Ave. will disturb an existing chip seal road and a concrete drainage valley pan.  Completion of the project is expected in October of 2019.  The project total cost for construction and project management is approximately $678,000.

The Town of Pinedale 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.  The Town of Pinedale anticipates no environmental issues, impacts, or necessary mitigation during the project.

DEQ is granting an exclusion because the project area has previously been disturbed.  The water and sewer line construction under South Fremont Ave. is all replacement of existing infrastructure.  The work taking place along South Sublette Ave. will disturb an existing chip seal road and a concrete drainage valley pan.   This project will be completely constructed in previously disturbed ground, specifically ground disturbed by previously installed sewer and water lines, road ways, and a drainage valley pan. 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 Pinedale, 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.
