Categorical Exclusion Determination, City of Riverton, WY, West Main Street Waterline Replacement Project

The Department of Environmental Quality/Water Quality Division (DEQ) has conducted a review of the proposed City of Riverton - West Main Street Waterline Replacement 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 will replace approximately 7,000 LF of existing 14-inch water main with 18-inch PVC main. The existing 14-inch steel pipe was installed in 1962 and has shown signs of age with multiple and continued leaks. The new water transmission line will be upsized to accommodate future growth in Pressure Zone 1.

The City 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 will be completed in previously disturbed ground, specifically ground disturbed by the existing water main and highway infrastructure. No work shall occur in the waters of the U.S.

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 the City of Riverton, Wyoming.

The determination shall become effective upon distribution by the Department and may be re-evaluated and the determination changed at any time that adverse information is made available. The documentation to support this decision will be on file in the DEQ Cheyenne Office and is available for public review upon request. To request a copy of the categorical exclusion, contact:
