Information provided for our review <br /> included the certified laboratory analysis notarized in the State of Texas on 20 October 1999, copy of <br /> Federal Code of Regulations (40 CFR Parts 400-424 and Parts 87-135), specifications,Base-Seal <br /> Products Warranty, Material Safety Data Sheet (MSDS), and letters of recommendation from previous <br /> Base-Seal clients. <br /> The application of this polymer involves the spraying of the product on stockpiles of contaminated soil <br /> and debris. The purpose is to prevent erosion of stockpiles located on Installation Restoration Site 19 <br /> which have been disturbed as part of a recent Removal Action. The Navy anticipates acquiring <br /> additional funds to finish the Removal Action in the near future. In the mean time, the application of the <br /> polymer is proposed to prevent soil erosion. The Navy has also stated that silt fences will be installed <br /> around the entire area in anticipation of the rainy season. <br /> Based on our review, we find the material acceptable for application on Site 19. Please inform the <br /> Board 48 hours prior to application so we may plan to observe operations. <br /> If you have any questions please contact me at (916) 255-3078 or schwabkArb5s.swrcb.ca. osovv. <br /> J::A Schwab <br /> Associate Engineering Geologist <br /> cc: Mr. Jim Austreng,Region 1, DTSC <br /> Mr. Ron Rowe, San Joaquin Environmental Health Dept., Stockton <br /> Mr. Scott Flint, Dept. of Fish and Game, Sacramento <br /> Mr. Jay Jahangiri, Port of Stockton <br /> Ms. Christine Baumgardt, Luce,Forward,Hamilton and Scripps, San Diego <br /> KAS:NCTS Sitel9l3aseSeal <br /> California Environmental Protection Agency <br /> Qa Recycled Paper <br />
