i <br /> t <br /> VAPOR RECOVERY RESULTS <br /> As of April 23 , 1993 the total system has recovered a calculated <br /> total of 17353 pounds of hydrocarbons, 4238 of which have been <br /> produced since the beginning of operations under the Authority to <br /> Construct <br /> As of July 21, 1992, the date it was destroyed, P1 had produced <br /> 2 96 pounds of hydrocarbons or an additional 1 63 pounds since <br /> the beginning of operation under the Authority to Construct See <br /> Table 1 <br /> VSBS was added to vapor extraction well P3-Swarm on. 7/27/92 The <br /> swarm in combination with VSBS has produced, as of 04/15/93 , 816 <br /> pounds of hydrocarbons, an additional 254 pounds since operation <br /> under the Authority to Construct, VSB5 is currently producing <br /> 1 22 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 April 15, 1993 , MW5 has produced a total of 10215 pounds, of <br /> which 1820 pounds have been produced during operations under the <br /> Authority to Construct . MW5 was transferred to use as a clean <br /> air in3ection well on 7/24/92 . On 7/27/92 , MW5 was shutdown as an <br /> air in3ection well . MW5 was again hooked up as a vapor extraction <br /> well on 8/03/92 <br /> On July 27, 1992, VSBS , VSB9 and VSB11 were added to the system <br /> As of April 15, 1993, these wells had produced the following <br /> amounts of gasoline VSB3 , 32 pounds; VSB9, 1095 pounds, and <br /> VSB11, 433 pounds <br /> Monitor well, MW 3 has not been used for vapor extraction during <br /> the operations under the Authority to Construct <br /> Currently the site is producing 8 . 65 pounds per day of TFH <br /> hydrocarbon The current CO2 emission rate indicates that <br /> approximately 60 lb of hydrocarbon are being destroyed per day by <br /> means of in-situ biological and/or chemical oxidation. <br /> -if you have any questions, please call (916) 668-5300 <br /> Ra utter <br /> Geologist <br /> cc Ms Mary Meays, San Joaquin County Health <br /> Ms Teresa Stuyt, San Joaquin Valley Air Quality <br /> page 6 of RG04, 04/30/93 <br />
