List any government approvals or permits that will be needed for your proposal, if known. A Mason County Shoreline Substantial Development permit, Building Permits, a Special Use permit, and Environmental Health sewage/water permits, plus a Geotechnical Report and Access Connection Permit from the WSDOT. 11.Give a brief, complete description of your proposal, including the proposed uses and the size of the project and site. There are several questions later in this checklist that ask you to describe certain aspects of your proposal. You do not need to repeat those answers on this page. (Lead agencies may modify this form to include additional specific information on project description.) A 6,000 gallon above grade marine fuel storage tank shall be added to the site, including a 449 square foot concrete pad and a fence, plus fuel lines from the tank to the dock. The fence, pad, and tank shall be located 75 feet landward of the ordinary high water line and MHHW.

Salmonids are salmon, trout and chars, e.g. bull trout. For our purposes, "ESA listed salmonids" is defined as fish species listed as endangered, threatened or being considered for listing . If ESA listed species are present or ever were present in the watershed where your project will be located, your project has the potential for affecting them, and you need to comply with the ESA. The questions in this section will help determine if the ESA listings will impact your project The fish Program Manager at the appropriate Department of Fish and Wildlife (DFW) regional office can provide information for the following two questions. 1. Are ESA listed salmonids currently present in the watershed in which your project will be located? Yes X No Please describe. Puget Sound Chinook, Bull Trout, and Hood Canal Summer-Run Chum. 2. Has there ever been an ESA listed Salmonid stock present in this watershed? Yes X No Puget Sound Chinook and Bull Trout, though it's theorized that, historically, the former did not occur in South Sound in large numbers. If you answered "yes" to either of the above questions, you should complete the remainder of this checklist PROJECT SPECIFICS: The questions in this section are specific to the project and vicinity. 1.
