Our Project Number: E07171A Page 5 of 10 October 31, 2007 office found records for the subject property under the name of Jose Viramontes. (Appendix f F). The following agricultural chemical use reports were provided by Ms. Gallego: Table 1 —Agricultural Chemical Use Reports Product Name Active Ingredient 02 103 04 05 06 07 Chloropicrin Chloropicrin X Sulfur Dust Sulfur X Pasada Makhteshim-A an Imidaclo rid X Omite Uniroyal Pro ar ite X According to Ms. Gallego, when a chemical for which a permit has been issued is applied to a field, the use report must be filed with the Agricultural Commissioner. The use reports do not include chemicals for which a permit is not required.$ The EPA's Restricted Use Products (RUP) Report9 was searched for the chemicals reportedly applied to the subject property. Based on this source, it appears that, of the agricultural chemicals reportedly applied to the subject property, chloropicrin is an RUP. The U.C. Davis Extension Toxicology Network (EXTOXNET) web site10 and the Pesticide Management Education Program (PMERP) at Cornell University web site" were consulted for additional information on these chemicals. According to EXTOXNET", "Chloropicrin is a clear, colorless, oily liquid with a strong, sharp, highly irritating odor...Chloropicrin has been used as an insecticide since 1917 and as a soil fumigant since 1920...The primary use today is for preplant soil fumigation to control soil borne fungi, diseases and nematodes...Undiluted chloropicrin is highly toxic by ingestion or direct contact with the skin or eyes. According to the American Conference of Governmental Industrial Hygienists, airborne exposure to 0.3-0.37 ppm (2-2.5 mg/meters cubed) for 3-30 seconds, results in eye irritation. This response is reported to be highly variable among individuals and tearing (lachrymation) may occur at airborne exposures of 0.15-0.3 ppm (1-2 mg/meters cubed). Inhalation exposure to 4 ppm (26 mg/meters cubed) for a few seconds may cause some degree of incapacitation (261) and an exposure of a few seconds to 15 ppm (100 mg/meters cubed) can cause injury to the respiratory track. Exposure to concentrations above 15 ppm can result in lacrimation, vomiting, and if allowed to continue for a minute or longer, can cause pulmonary edema and possibly death...The half-life of chloropicrin in sandy loam soil was 8-24 hours and 4.5 days with carbon dioxide being the terminal breakdown product. Chloropicrin moves rapidly in soils within twelve inches of injection but may diffuse to a maximum depth of four feet in sandy soil...Since it is only slightly soluble in water, it will not move rapidly in aquatic environments". 8 Personal Communication, November 28, 2005. 9 U.S. Environmental Protection Agency (EPA), June 2003, Restricted Use Products (RUP) Report. 10 University of California, Davis, Extension Toxicology Network(EXTOXNET), http://extoxnet.orst.edu/ghindex.html 11 Cornell University, Pesticide Management Education Program, http://pmep.cce.cornell.edu/ 12 http://extoxnet.orst.edu/cgi-webglimpse/webglimpse.cgi?ID=1&query=chloropicrin&case=on ... 902 Industrial Way•Lodi,CA 95240.209.367.3701 •Fax 209.369.4228 02007 Neil O.Anderson&Associates,Inc.
