The <br /> swarm in combination with VSB5 has produced, as of 10/06/93 , 884 <br /> pounds of hydrocarbons, an additional 325 pounds since operation <br /> under the Authority to Construct, VSB5 is currently producing <br /> 0 18 pounds per day, see Table 1 . On 8/26/92 , the P3-Swarm was <br /> disengaged from the vapor extraction system. <br /> Before being shut down on 7/24/92 , vapor extraction well EX <br /> produced 131 31 pounds of hydrocarbons, 4 18 pounds of which were <br /> produced under the Authority to Construct, see Table 1 <br /> As of August 26 , 1992 , MW1 had produced a total of 2534 pounds, <br /> of which 69 75 pounds have been produced during operations under <br /> the Authority to Construct MW1 was shut down on 7/24/92 . <br /> As of October 6, 1993 , MWS has produced a total of 10534 pounds, <br /> of which 2091 pounds have been produced during operations under <br /> the Authority to Construct MW5 was transferred to use as a <br /> clean air infection well on 7/24/92 On 7/27/92, MW5 was shutdown <br /> as an air infection well MW5 was again hooked up as a vapor <br /> extraction well on 8/03/92 <br /> On July 27, 1992, VSB3 , VSB9 and VSB11 were added to the system <br /> As of October 6, 1993 , these wells had produced the following <br /> amounts of gasoline VSB3 , 58 pounds, VSB9, 1045 pounds, and <br /> VSB11, 511 pounds. <br /> Monitor well, MW 3 has not been used for vapor extraction during <br /> the operations under the Authority to Construct . <br /> i <br /> Page 5 of R604, 10/21/93 <br />
