Working To Restore Nature <br /> Addendum One to Remedial Action Plan March 11 1993 <br /> Coca-Cola Former Distribution Facility, Stockton, California 54006.01 <br /> = 51.4 parts benzene = 51.4 ppmv <br /> F 106 parts vapor <br /> And, the Benzene Extraction Rate during Month 2 is: <br /> S <br /> = 51.4 ppmv benzene x 71 lb TPHg/day = 4.6 lb benzene/day <br /> 789 ppmv TPHg <br /> � F <br /> _ <br /> Month 2: Benzene Emission Rate after Abatement by Thermal Oxidizer <br /> F ' Using the worst case 95% destruction efficiency achieved by the thermal oxidizer, the <br /> approximate initial benzene mass emission rate after abatement is: <br /> Benzene Mass Emission Rate from Stack = (1 - 0.95) 4.6 lb benzene/day <br /> = 0.23 lb benzene/day <br /> MONTH 3 TPHg EXTRACTION RATES AND EMISSION RATES AFTER ABATEMENT <br /> BY THERMAL OXIDIZER <br /> According to Shell Development/Shell Oil Company(1990), extracted TPHg concentration <br /> F is predicted to decrease by 90% during about the third or fourth month of operation of the <br /> VES. Since only one well will be on line during the first month, this 90% decrease is <br /> predicted to occur during the third month, rather than the second month. The decrease is <br /> based on 90% of the startup TPHg concentration of 1,185 ppm. <br /> Month 3: TPHg Extraction Rate <br /> LFDuring Month 3 the average TPHg concentration is predicted to be 10% x 1,185 ppmv = <br /> 119 ppmv. Thus,with 3 wells operating during month 3, the projected TPHg extraction rate <br /> IT' <br /> before abatement is: <br /> 119 1 TPH¢ x 225 Fe x 1,440 min x 28321 air x 1 mole PHg x 100 g x 1 lb <br /> i 1,000,0001 air min day 1 ft' 22.4141 vapor mole TPHg 454 g <br /> = 10.71b TPHg <br /> LF day . <br /> = 321 1b TPHg/month <br /> i <br /> i <br /> L F <br />
