Notice of Exemption

Exempt Status
Categorical Exemption
Type, Section or Code
Section 15301 (b)(c) Existing Facilities
Reasons for Exemption
The Project involves the repair, maintenance, and minor alteration of existing structures, including access roads and watercourse crossings that access utilities that provide electric power. The Project will not result in the expansion or use beyond what currently exists and will increase public safety. The Project includes adding rock armor to two existing watercourse crossings, reestablishing natural drainage patterns to reduce erosion and improve water quality at eight intermittent/ephemeral creek crossings, and restoring an historic watercourse diverted by a road to resemble more historic conditions. Road treatments include outsloping, re-grading, and the construction of rolling dips. These treatments will reduce road erosion and fine sediment delivery to watercourses and will hydrologically disconnect numerous sections of road from tributaries within the Lewiston Lake and Trinity River, watersheds.
