CATEGORICAL EXCLUSION DETERMINATION

 

For the City of Gillette – Project: Interstate Industrial Park L.I.D. and Street Improvements

Campbell County, Wyoming

The Department of Environmental Quality/Water Quality Division (DEQ) has conducted a review of the proposed Interstate Industrial Park L.I.D. and Street 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 Interstate Industrial Park is generally located west of Garner Lake Road, immediately south of Interstate 90.  The proposed project will install a new water distribution system throughout the industrial park and connect it to the City’s water mains in the area, replacing the District’s private production and distribution systems.  The current system is aged, under-sized, provides no redundancy, the well is nearing the need of major rehabilitation, and the service lines are not individually metered.  The new system will provide higher water pressures, increased flows for fire protection, improved water quality, individual meters, and a more reliable source of water to the subdivision.  The project will also include improvements to 2nd Street and Conestoga Drive within the subdivision in conjunction with the water system improvements.  The existing pavements are beginning to fail and portions will be removed for the installation of the new water system, therefore they will be reconstructed providing new surfacing and improved ride-ability.

Based on current cost estimates, the City of Gillette plans to borrow $2,050,000 from the Wyoming Drinking Water - State Revolving Loan Fund Program administered by the Wyoming Office of State Loans and Investments to fund the water system improvements.  The City of Gillette plans to repay the loan with water fund revenues generated through rates for the City’s water distribution system.  The City of Gillette will fund the 2nd Street improvements estimated to be in the amount of $1,720,000 with Optional 1% Sales Tax revenues budgeted within the annual Pavement Management System program.  The street improvements for Conestoga Drive will occur at a later time and its funding will be established in a future budget.

The City of Gillette 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 replaces existing infrastructure.  This project will be completely constructed in previously disturbed ground, specifically ground disturbed by the installation of existing water mains and sanitary sewer mains and the construction of paved roadways.  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 this area of the City of Gillette, Campbell County, Wyoming.

The documentation to support this decision will be on file in the DEQ Casper Field Office and is available for public scrutiny upon request.
