CATEGORICAL EXCLUSION DETERMINATION

For the South Park Service Center Improvement and Service District’s Centralized Sewer Collection System and Water System Improvements Projects, Teton County, Wyoming 

The Department of Environmental Quality/Water Quality Division (DEQ) has conducted a review of the proposed South Park Service Center Improvement and Service District’s Centralized Sewer Collection System and Water System Improvements Projects 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 SPSC ISD Centralized Sewer Collection System Project consists of the installation of a new collection system to replace inadequate, onsite treatment systems. The SPSC ISD Water System Improvements Project consists of the replacement of 35-year-old, deteriorated water system components. The estimated cost of the sewer system improvements is $840,876 and the water system improvements, $908,066.   The SPSC ISD’s Pre-Application was approved by the Wyoming State Loan and Investment Board on April 12, 2018 for a Clean Water State Revolving Fund (CWSRF) loan in the amount of $593,158, with $197,719 principal forgiveness, utilizing $50,000 of reserves to fund the project. The SPSC ISD’s Pre-Application was approved by the Wyoming State Loan and Investment Board on April 12, 2018 for a Drinking Water State Revolving Fund (DWSRF) loan in the amount of $643,550, with $214,516.50 principal forgiveness, utilizing $50,000 of reserves to fund the project. Increased user fees and assessments will repay the loan. The average rate increase is estimated to be approximately $158.54/month per lot to repay the CWSRF loan and approximately $172.01/month per lot to repay the DWSRF loan; both loans have terms of 2.5% and 20 years.

The SPSC ISD has inspected and is familiar with the project area.  They found no evidence and have no knowledge that the project area contains endangered/threatened species, suitable habitat for endangered/threatened species, migratory birds, eagles, jurisdictional waters of the United States, or prime agricultural lands.  The SPSC ISD 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 replaces existing infrastructure and constructs facilities adjacent to and on the same property as existing facilities. This project will be completely constructed in previously disturbed ground, specifically ground disturbed by an existing buried waterline within a roadway.  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 Teton 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.
