The Department of Environmental Quality / Water Quality Division (DEQ) has conducted a review of the proposed SMP Emergency Power and HVAC Upgrades 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 SMP Emergency Power and HVAC Upgrades Project involves the replacement of three emergency power generators and one boiler, all of which are thirty (30) years old. The loss of any of these pieces of equipment poses a potential public health issue. Based on current cost estimates, Shoshone Municipal Pipeline plans to borrow $1,305,480.00 from the Wyoming Drinking Water State Revolving Fund administered by the Wyoming Office of State Lands and Investments. The loan will be repaid from the customers’ existing water sales and tap fee bills. There will be no increase in the customers’ monthly water bills to pay for this loan. The loan terms will be 2.5% interest and 20 years.

DEQ is granting an exclusion because all of the work is to be completed within existing buildings. There will not be any new construction. The upgraded emergency power generators and the upgraded boiler are replacing 30-year-old equipment. The new equipment will be more energy efficient and both the emergency power generators and the boiler will comply with stringent emission standards as set by the Environmental Protection Agency. This project will be completely constructed within existing buildings and will not disturb any new ground. 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 of the area of Cody, Park County, Wyoming.

Shoshone Municipal Pipeline 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 Fund Program contract conditions.

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.
