PROJECT DESCRIPTION: Puget Sound Energy (PSE) is requesting a Hearing Examiner Conditional Use Permit, Environmental (SEPA) Review, Site Plan Review,
and a Special Fence Permit for proposed Talbot Hill Substation improvements located at 2400 S Puget Dr (parcel number 2023059066). The project site totals 13.4 acres and is zoned Residential-8
(R-8). PSE is proposing to install six Current Limiting Reactors (CLRs) within a fenced enclosure adjacent to the existing Talbot Hill Substation. The proposed CLRs are large, highly
customized coils that are each supported by three insulators. For safety and security purposes, the CLRs will also be installed on elevated pedestals with foundations, and enclosed by
an eight foot security fence. A new 190 foot long by 85 foot wide gravel pad will be constructed to support the CLRs and the enclosure. The equipment will be accessed by a new approximately
330 foot long by 15 foot wide gravel access road that will connect to an existing gravel driveway which extends from Puget Dr. SE to the substation entrance on PSE parcel number 2023059003.
Stormwater from the new impervious surface will be split between a new infiltration drywell and the existing stormwater pond that serves the substation. No modifications to the existing
stormwater pond will occur. The proposal also includes the installation of a new three-pole 230 kV H-frame (77 feet, 67 feet, and 77 feet above grade) outside the fenced area to accommodate
a reconfiguration of an existing transmission line needed as part of the substation modernization. No tree or significant vegetation removal is proposed as part of this project. The
project site contains moderate coalmine hazards, moderate landslide hazards, and sensitive slopes (within 50 feet). The applicant has submitted a Technical Information Report (TIR) and
Geotechnical Engineering Study with the application.
Appeals of the environmental determination must be filed in writing on or before 5:00 p.m. on July 5, 2019, together with the required fee with: Hearing Examiner, City of Renton, 1055
South Grady Way, Renton, WA 98057. Appeals to the Examiner are governed by City of RMC 4-8-110 and information regarding the appeal process may be obtained from the Renton City Clerkâs
