VSB5 was added to vapor extraction well P3-Swarm on 7/27/92 The swarm in combination with VSB5 has produced, as of 06/18/93 , 878 pounds of hydrocarbons, an additional 316 pounds since operation under the Authority to Construct, VSB5 is currently producing 0 .37 pounds per day, see Table 1. On 8/26/92, the P3-Swarm was disengaged from the vapor extraction system Before being shut down on 7/24/92 , vapor extraction well EX produced 131 31 pounds of hydrocarbons, 4 18 pounds of which were produced under the Authority to Construct, see Table 1 . As of August 26, 1992, MW1 had produced a total of 2534 pounds, of which 69 75 pounds have been produced during operations under the Authority to Construct MW1 was shut down on 7/24/92 As of June 18 , 1993, MW5 has produced a total of 10406 pounds, of which 2012 pounds have been produced during operations under the Authority to Construct MW5 was transferred to use as a clean air in3ection well on 7/24/92 On 7/27/92 , MW5 was shutdown as an air injection well MW5 was again hooked up as a vapor extraction well on 8/03/92 On July 27, 1992 , VSB3 , VSB9 and VS211 were added to the system As of June 18 , 1993 , these wells had produced the following amounts of gasoline . VSB3, 39 pounds; VSB9, 1153 pounds, and VSB11, 520 pounds . Monitor well, MW 3 has not been used for vapor extraction during the operations under the Authority to Construct . Currently the site is producing 6 . 83 pounds per day of TFH hydrocarbon. The current CO2 emission rate indicates that approximately 37 7 pounds of hydrocarbon are being destroyed per day by means of in-situ biological and/or chemical oxidation If you have any questions, please call (916) 668-5300 7'� L Roy ler Geo ogist cc Ms Mary Meays, San Joaquin County Health Mr Gary Reeves, San Joaquin Valley Unified Air Pollution Control District page 6 of R604, 07/09/93
