September 22, 2014 Delinda Robinson Monterey County Resource Management Agency Planning Department 168 W. Alisal Street, 2nd Floor Salinas, CA 93901 [email protected] Re: California Flats Solar Project – PLN120294; SCH#2013041031 Draft Environmental Impact Report Dear Ms. Robinson: California Flats Solar, LLC (Applicant), a wholly owned subsidiary of First Solar, Inc., hereby provides to the County of Monterey (County) its written comments on the Draft Environmental Impact Report (EIR) for the California Flats Solar Project (Project), issued by the County on August 6, 2014. Our written comments consist of both this letter and the documents contained in the attachments, each of which is incorporated herein by reference. At the outset, we thank County staff and the County’s consultant, Rincon Consultants, Inc. (Rincon), for their hard work in compiling and preparing this Draft EIR in support of the Project. We also appreciate the significant public outreach efforts and agency consultation that has been conducted for the Draft EIR by the County under the California Environmental Quality Act (CEQA). We have provided our comments in the two attached tables, which are organized by chapter and section in the Draft EIR. The first table, “Table 1 – Comments,” contains substantive comments on specific issues in the Draft EIR for the County’s consideration. Please note that we have included three (3) figures as part of our comments that relate to certain comments in Table 1. The second table, “Table 2 – Errata,” contains factual and typographical revisions that should be incorporated in the Final EIR. We have also attached two golden eagle survey reports for 2014 which provide nest surveys and on- going survey data for golden eagle within a ten mile radius of the Project site, and a 2013 scent dog survey report assessing the presence of San Joaquin kit fox on the Project site. This updated survey data does not present any significant new information but, rather, confirms the data identified and analyzed in the Draft EIR as part of the Applicant’s ongoing effort to track relevant environmental resource information. We appreciate the considerable time and effort that the County and Rincon have devoted to the scoping process, data development, impact analysis, mitigation measure formulation and overall preparation of this Draft EIR. Our comments are intended to add transparency and further explain the findings contained in this draft document, so that the Final EIR accurately summarizes all of the relevant data, analysis and conclusions. First Solar, Inc. 135 Main Street, 6th Floor Telephone 415 935 2500 San Francisco, CA 94105 Facsimile 415 935 2501 www.firstsolar.com Please feel free to contact us at any time if you have any questions or would like to discuss these comments.

These changes are necessary based on more refined design information from PG&E and in order to further reduce potential impacts associated with the switching station. The proposed changes would not result in any additional environmental effects or cause an increase in severity of an identified effect and, in fact, would further reduce impacts to certain plant species. The extent of environmental effects would be consistent with or less than those evaluated in the Draft EIR. The overall size of the PG&E switching station and northern substation would remain the same and the new location for the switching station and substation is within the SDA. A small portion of the transmission line easement is Chapter 2 FIGURE 2.4a, 1. 2-15 located outside of the SDA; however, potential impacts within this area would be limited to (Project Description) 2.4e, 2.4h transmission line improvements. The limited ground disturbance within the transmission line easement were previously described and evaluated in the Draft EIR. Overall, this change in layout would lessen the extent of impacts to sensitive plant species as compared to the current design. As currently proposed, the substation and switching station would directly impact both Navarretia nigelliformis and California macrophylia. The proposed revisions, as shown on the attached site plan, would completely avoid impacts to California macrophylia and significantly reduce the extent of impacts to Navarretia nigelliformis associated with current location of the substation and switching station. Overall, the proposed revision would lessen the extent of potential impacts associated with the proposed project. The proposed changes would not result in any additional adverse environmental effects, cause an increase in severity of an identified impact, or result in a substantial change to the project that would deprive the public meaningful opportunity to comment on the project or a significant environmental effect. Add APM-10. The project proponent will prepare a Bird and Bat Conservation Strategy (BBCS) to identify conservation measures to minimize avian impacts, describe the avian use of the site, and describe a post-construction avian mortality monitoring program. This Avian Mortality Monitoring Chapter 2 2. 2-91 TABLE 2.4 Program (AMMP) will monitor operational effects of the project on avian species. The AMMP will (Project Description) include the following elements: • Surveys of the solar arrays for bird mortality during the initial operations and maintenance phase; Table 1 – Comments California Flats Solar Project, Draft Environmental Impact Report, County of Monterey, California, August 6, 2014 California Flats Solar, LLC - September 22, 2014 Figure or Table Document Chapter Page Number Comment and/or Reference Number Comment Comment • Protocols for data collection, documentation, and reporting to the County; • Protocols to assess searcher efficiency and carcass removal; and • Minimum credentials of monitoring personnel and/or appropriate training. Add APM-11: The applicant shall prepare a design level drainage analysis that will ensure that project facilities are not placed in areas where they would be subject to significant flood or erosion hazards or affect the existing capacity of affected watercourses. The design level drainage study will incorporate the following flood-risk and erosion avoidance measures contained in the Preliminary Drainage Report (RBF 2013) and in the Preliminary Drainage Analysis Addendum (Wallace Group 2014): • No modules shall be placed in areas where the product of the flow depth and flow velocity is greater than 9 square feet per second (corresponding to a hazard level 3, as defined in the Preliminary Drainage Report) during a 100-year, 24-hour storm event; • No transformers, substations, or inverters shall be placed in areas where the flow depth exceeds 2 feet (corresponding to a hazard level 3, as defined in the Preliminary Drainage Report) during a 100-year, 24-hour storm event; Chapter 2 3. 2-91 TABLE 2.4 • Transformers, substations, or inverters constructed in areas where any inundation is expected (Project Description) to occur should be placed a minimum of 1 foot above the 100- year water surface elevation; • Solar modules constructed in areas where any inundation is expected to occur should be placed a minimum of 6-inches above the 100- year water surface elevation; and • Tracker actuator motors constructed in areas where any inundation is expected to occur should be placed a minimum of 6-inches above the 100- year water surface elevation. In addition, the design level drainage analysis shall contain measures to ensure that any project-related improvements within 50 feet from the top of bank of on-site drainages will not result in significant erosion related hazards and that these improvements will not affect the existing capacity of the affected watercourse, as required by Chapter 16.16 of the Monterey County Code. Prior to the issuance of grading permits, the applicant shall submit the design-level drainage analysis to the Monterey County Water Resources Agency for review and approval. Impact AES-1: The temporary construction effects associated with the proposed project do not rise to Section 4.1 the level of significance warranting mitigation. The second sentence in the “Impact” column should be 4. 4.1-1 TABLE 4.1.1 (Aesthetics) revised as follows: “Potential impacts during
