MONITORING AND REPORTING PF&AM NO. R5-2010-0803 • -3- <br />JOHN <br />3 -JOHN TAYLOR FERTILIZERS CO., INC., WILBUR-ELLIS COMPANY <br />STOCKTON FACILITY, SAN JOAQUIN COUNTY <br />REQUIRED ACTIONS <br />IT IS HEREBY ORDERED that, pursuant to California Water Code section 13267, Wilber - <br />Ellis shall: <br />1. Conduct monitoring and reporting in compliance with the following specifications. <br />2. (a) As shown on Figure 1, there are seven (7) existing shallow groundwater <br />monitoring wells (MW -1, MW -2, MW -3, MW -4, MW -5, MW -6 and MW -7) ranging <br />from 26.51 to 32.35 feet bgs depth. The groundwater monitoring program for the <br />seven shallow monitoring wells and any wells installed for groundwater <br />monitoring subsequent to the issuance of this MRP, shall be sampled semi- <br />annually as shown in Table 1. All wells shall be monitored semi-annually for <br />Depth to Groundwater. Wells that must be sampled semi-annually shall be <br />sampled during the first and third quarters. <br />Table 1. <br />Groundwater Monitoring Schedule for Groundwater Monitoring Wells <br />Constituents <br />EPA Analytical <br />Method <br />Maximum <br />Practical <br />Quantitation Limill <br />1 <br />Monitoring Wells <br />Depth to Groundwater <br />--- <br />0.01 foot <br />All <br />otal Oxidized Nitrogen <br />353.2 <br />1.0 mg/1 <br />All <br />olatile Organic Compounds <br />82606 <br />0.5-50 µg/12 <br />All <br />1,2-dichloropropane <br />8260B <br />0.5 ug/I <br />All <br />1,2,3-trichloropropane <br />SRL 524M -TCP <br />0.005 µg/I <br />All <br />Bromacil <br />632 <br />1µg/I <br />All <br />For nondetectable results. All concentrations between the Method Detection Limit and the <br />Practical Quantitation Limit shall be reported as trace. <br />2 Maximum PQLs for bromomethane, dichlorodifluoromethane, Freon 113 and MTBE are 1 µg/I, <br />Maximum PQLs for 1,2,3 -TCP and 1,2-DCP be 5.0 and 0.50 µg/I respectively. <br />(b) In addition, any deep monitoring wells (approximately 50 feet bgs) installed <br />subsequent to the issuance of this MRP, shall also be sampled semi-annually for <br />at least two consecutive sampling events for constituents shown in Table 2. If all <br />constituents in an analytical suite are not detected in two consecutive semi- <br />annual events in the deep monitoring well(s), that analytical suite may be <br />removed from the monitoring schedule for that well, and shall then follow the <br />
