Vulcan Avenue Encinitas, CA 92024-3633 Dear Mayor Davis: Thank you for your letter of May 21,1993, requesting that the City of Encinitas be considered as a candidate site for the San Onofre mitigation kelp reef. The site selected for the kelp reef must meet the criteria of Condition C of Permit 183-73 (copy enclosed) among which is the requirement that it be located near the San Onofre kelp bed which was impacted by operation of the San Onofre Nuclear Generating Station. Of all the possible sites considered for the kelp reef site by the Southern California Edison Company, Encinitas was the farthest away from San Onofre. Because several other sites close to San Onofre met the permit criteria, Encinitas was ruled out of further consideration as a candidate site for the kelp reef. As described in more detail in the enclosed copy of my letter to Sally Vigil of the City of Carlsbad, the purpose of the kelp reef is to replace lost and damaged kelp resources at the San Onofre kelp bed and to produce a productive kelp reef ecosystem. The reef will be designed to minimize any disturbance of sand movement, but its primary purpose is not to be a mode of shoreline protection. The details of the survey of potential sites for the artificial reef are contained in a report prepared for Southern California Edison Company by Eco-Systems Management Associates, Inc. in January 1993. This report, "Survey of Potential Sites for the Construction of an Artificial Reef; Final Revised Report" consists of more than 150 pages including appendices and figures. If you wish to review this report, it should be available directly from Eco-Systems Management Associates, Inc., or from Mr. Bob Grove of the Southern California Edison Company.

Grove, Southern California Edison Company Enclosures: Kelp reef site selection criteria from Permit 183-73 Condition C Letter to Sally Vigil, City of Carlsbad encinitiwp CONDITON C: KELP REEF MITIGATION The permittee shall, in consultation with the Executive Director, select a site and construct an artificial reef as mitigation for the resource losses at the San Onofre Kelp Bed (SOK) caused by the San Onofre Nuclear Generating Station (SONGS). The reef shall be designed to replace the lost and damaged resources at the San Onofre Kelp Bed Reef and produce a persistent giant kelp forest and associated ecosystem. The reef shall be located in the vicinity of the SONGS, but outside the influence of the SONGS discharge plume and water intake. After selecting potential sites, and conducting a pre-construction site assessment at these potential sites, the permittee shall select a site and design a reef which meets the standards and objectives listed below. The permittee shall submit the final reef plan to the Commission for its review and approval. 1.0 SITE SELECTION Three or more potential reef sites shall be selected based on, but not limited to, the following criteria: 1) Location as near as possible to the San Onofre Kelp Bed, and preferably between Dana Point (Orange Co.) and the Pendleton Artificial Reef (San Diego Co.), but outside the influence of the SONGS discharge plume and water intake; 2) Minimal disruption of natural reef or cobble habitats and sensitive or rare biotic communities; 3) Suitable substrate with low mud and/or silt content (e.g. hard-packed fine to coarse grain sand, exposed cobble or bedrock without an established biological community, or cobble or bedrock covered with a thin layer of sand); 4) Location at a depth locally suitable for kelp growth and recruitment; 5) Location near a persistent natural kelp bed; 6) Location away from sites of major sediment deposition; 7) Minimal interference with uses such as vessel traffic, vessel anchorages, commercial fishing, mariculture, mineral resource extraction, cable or pipeline corridors; 8) Location away from power plant discharges, waste discharges, and dredge spoil deposition sites; 9) Location that will not interfere with or adversely affect resources of historical or cultural significance such as shipwrecks and archeological sites. 6775N STATE OF CALIFORNIA—THE RESOURCES AGENCY ,TEM 3 PETE WILSON, Governor CALIFORNIA COASTAL COMMISSION 45 FREMONT, SUITE 2000 SAN FRANCISCO, CA 94105-2219 VOICE AND TDD (415) 904-5200 June 23, 1993 Sally Vigil, Chairperson Beach Erosion Committee Engineering Department City of Carlsbad Carlsbad, CA Dear Ms. Vigil: Thank you for your letter of May 17, 1993 requesting the California Coastal Commission to require Southern California Edison Company to study the potential of locating part of the San Onofre Nuclear Generating Station kelp bed mitigation reef offshore the northerly coastline of the City of Carlsbad. California Coastal Commission Permit 183-73, Condition C, requires Southern California Edison Company to select a site and to construct an artificial reef as mitigation for the resource losses at the San Onofre Kelp Bed caused by the San Onofre Nuclear Generating Station. The site selected must meet specific criteria in the Coastal Commission permit. The Commission must approve the final kelp reef plan and grant a separate coastal permit before construction on the reef can begin. The reef must be designed to replace the lost and damaged resources of the San Onofre Kelp Bed reef and to produce a persistent kelp forest and associated ecosystem. The purposes of the mitigation kelp reef are to replace lost and damaged kelp forest resources and to produce a persistent kelp forest and associated ecosystem. I have attached a copy of the relevant part of Permit 183-73 for your information. We share your concern about the sand and the sand supply for local beaches. Southern California Edison Company is required by Permit 183-73, Condition C, section 1.1 to predict the effect of the mitigation reef on local sand transport and local beaches. Although it is unlikely that the mitigation kelp reef will have an effect on the local beaches because the reef must be built offshore of the main zone of sand motion to achieve its required objectives. Nevertheless, contractors for Southern California Edison Company are currently studying the potential problem by a combination of computer models and field experiments off the northerly coastline of the City of Carlsbad. When the study is complete there will be a more definitive answer to this question. With regard to your specific request, Southern California Edison Company has already studied the feasibility of placing the mitigation reef off the northerly coast of Sally Vigil, Chairperson June 23, 1993'_ Page 2 Carlsbad, but this and other sites south of Carlsbad were ruled out for a variety of reasons including long distance from the impact site (San Onofre) compared to other potential sites, and because the available area with the appropriate conditions for the kelp reef was not large enough to meet the requirements of the Coastal Commission permit. The details of the survey of potential sites for the artificial reef are contained in a report prepared for Southern California Edison Company by Eco-Systems Management Associates, Inc. in January 1993. This report, "Survey of Potential Sites for the Construction of an Artificial Reef; Final Revised Report" consists of more than 150 pages including appendices and figures.
