MEMBERS OF THE BOARD JOHN C. ZARAGOZA Chair STEVE BENNETT LINDA PARKS KELLY LONG PETER C. FOY BOARD OF SUPERVISORS COUNTY OF VENTURA 625 WEST HILLCREST DRIVE, THOUSAND OAKS, CA 91360 March 7, 2017 Ms. Stephanie Jennings NEPA Document Manager, SSFL Area IV EIS U.S. Department of Energy 4100 Guardian Street, Suite 160 Simi Valley, CA 93063 Dear Ms. Jennings: Thank you for the opportunity to comment. Unfortunately the EIS does not analyze cleaning the DOE site to the agreed upon stipulations in the 2010 Agreement On Consent. Instead, hundreds of thousands of cubic yards of soil, some with known significant chemical and radiological contamination that would be covered by the AOC, are exempted from remediation. The public's health must be your first priority. A clear analysis of a project that will remediate contamination as agreed upon in the AOC needs to be thoroughly evaluated in the EIS. The DOE must not leave unknown quantities and concentrations of contamination on site, nor avoid due diligence in analyzing full remediation of known contaminants in excess of background levels. The EIS's exemption of hundreds of thousands of cubic yards of soil, on the basis that it may impact biological or cultural resources, is premature, lacks transparency, reneges on DOE's agreement from the 2010 AOC, and if implemented, would threaten the public's health. The Ventura County Board of Supervisors strongly recommends that the EIS be consistent with remediation of DOE's SSFL site to the levels stipulated in the AOC. Sincerely, John Zaragoza, Chair, Board of Supervisors cc: Matt Rodriquez, Secretary, Cal EPA Barbara Lee, Director, DTSC Recycled PBPer
