<br /> Subject: Sierra Lumber Manufacturers, Inc. (Case No. 1) LOP Case No.: 490
<br /> 375 West Hazelton Avenue
<br /> Stockton, California 95203-3306
<br /> Dear Mr. Long:
<br /> On 10 September 2014, the San Joaquin County Environmental Health Department (EHD) met
<br /> with the Central Valley Regional Water Quality Control Board (Regional Board) to discuss site
<br /> closure of the Local Oversight Program Case 1 for Sierra Lumber Manufacturers, Inc. It has
<br /> been more than eight years since the nine monitoring wells associated with Case 1 were last
<br /> sampled and the Regional Board has directed that the monitoring wells be sampled before
<br /> closure can be considered for this site. Therefore, the EHD directs that groundwater samples
<br /> be collected from monitoring wells MW-1, MW-2, MW-3, MW-4A, MW-4B, MW-6 and MW-8 and
<br /> analyzed for total petroleum hydrocarbons as gasoline (TPH-g); benzene, toluene,
<br /> ethylbenzene and total xylenes (BTEX); methyl tertiary-butyl ether (MTBE), ethyl tertiary-butyl
<br /> ether (ETBE), tertiary-amyl methyl ether (TAME), di-isopropyl ether (DIPE), tertiary butyl alcohol
<br /> (TBA), 1,2-dichoroethane (1,2-DCA) and 1,2-dibromoethane (EDB).
<br /> The EHD directs that the results from the monitoring and sampling event be included in a
<br /> closure summary report that addresses the criteria set forth in the Low-threat Closure Policy
<br /> (LTCP) and that includes data listed in Table 1 of Appendix A of the Tri-Regional Guidelines.
<br /> Notify the EHD once the groundwater sampling event has been scheduled so that an inspector
<br /> can be present. If you have any questions, please contact Vicki McCartney at (209) 468-9852
<br /> or by email at vmccartnevCDi7sicehd.com.
<br /> Sincerely,
<br /> Victoria L. McCartney, REHS Nuel C. Henderson, Jr., PG
