Public Notice: CATEX notice for the SRF-Drinking Water Loan Program, Newcastle Well Project

For the City of Newcastle – Well House #5 and Water Supply System,
Weston County, Wyoming

The Department of Environmental Quality/Water Quality Division (DEQ) has conducted a review of the proposed City of Newcastle Well House #5 and Water Supply System 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 tie the recently drilled Newcastle No. 5 Well into the existing Newcastle well collection system. Groundwater from the No. 5 well will flow under artesian pressure to the existing pump station to be distributed to the users in Newcastle and/or to their storage facilities. Additionally, two existing old Transite collection lines from the No. 1 Well and No. 4 Well will be abandoned in place and replaced with PVC pipe. By combining the flows from No. 5 Well and No. 4 Well, the City will be able to match to production from No. 1 Well, allowing it to be taken off line for a significant period of time. Based on current estimates, the City of Newcastle plans to borrow $705,680 from the Wyoming Drinking Water State Revolving Loan Fund at 2.5% Interest for 30 years or a payment of $16,857.80 per year for 30 years. The expense of repayment of the loan was already figured into the current Water rates.

The City of Newcastle 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 the project consists of a minor expansion to an existing system near existing infrastructure and the project involves minor construction of ancillary facilities adjacent to and within existing facilities and on the same property. This project will be completely constructed in previously disturbed ground, specifically the No. 5 well site area, the existing access road to the No. 5 Well and the existing City Streets and Water Utilities yard area. 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 Newcastle and Weston 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 Stan Miller, SRF Project Engineer, DEQ Cheyenne Office, 200 W. 17th Street, Cheyenne, WY 82002, telephone (307) 777-5973, email
