CATEGORICAL EXCLUSION DETERMINATION
For the Town of Afton, WY, Afton North Waterline Replacement & Spring Overflow Upgrade,
Lincoln, County, Wyoming

The Department of Environmental Quality/Water Quality Division (DEQ) has conducted a review of the proposed Afton North Waterline Replacement & Spring Overflow Upgrade 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 includes the installation of new 6” and 8” diameter water transmission pipeline along U.S. Highway 89, north of Town. The transmission line on the west side of U.S Highway 89 is a replacement for a failing steel waterline. The line on the east side of Highway 89 is a looping connection from the new line on the west side to an existing waterline. The project also includes modification of the spring flap gate on the Town’s spring source located in Swift Creek Canyon approximately 5 miles east of Town.

The project is estimated to cost $1,000,000. The SRF loan amount will be $1,000,000. Repayment of the loan will come from water usage rates. It is anticipated that the monthly user fee will increase by $4.00 to pay for the loan.

The Town of Afton 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. There are no noteworthy environmental impacts associated with the project.

DEQ is granting an exclusion because the project will replace an existing undersized failing steel waterline with replacement occurring adjacent to previously disturbed trench line. A portion of the waterline will be new construction to create a loop in the system. The new construction will generally be located on private land which has been previously disturbed by farming or development. Work at the spring will replace existing flaps with no new disturbance occurring.

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 Afton, Lincoln, 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, Department of Environmental Quality, 200 W. 17th St. Suite 200, Cheyenne, WY 82002, Tel.
