SLC Public Utilities / NEPA Categorical Exclusions

Client: Salt Lake City Department of Public Utilities
Location: Salt Lake County, Utah

SAGE prepared Categorical Exclusion documentation for two Salt Lake City Department of Public Utilities projects. The first project involved replacement of the covers on the three primary anaerobic digesters at the Salt Lake City Water Reclamation Facility. Replacement of these covers would increase capture of methane gas and decrease greenhouse gas emissions. SAGE established that the proposed action would not significantly affect the environment and that it qualified for a Categorical Exclusion under the EPA’s NEPA implementing regulations.

The second project was a Bureau of Reclamation funded project to upgrade the Big Cottonwood Tanner Ditch Company culinary water system and convert an open ditch to pressurized irrigation. This action would result in a significant water savings by reducing loss from seepage and evaporation. The project involved the installation of a new pipeline and the change of use of a historic canal system. SAGE conducted wetlands and biological surveys and coordinated a cultural resource survey on the canal system. The documentation resulted in a finding of no significant impact and concurrence from the Bureau of Reclamation to proceed with the proposed action.
