MEMO 1 193 <br /> is - .a ,-•a. r-,TO : JACK RONSKO, PUBLIC WORKS DIRECTOR <br /> FROM :. LARRY HUGHES , FIRE CHIEF. _ -'•'•� = ="„rraeir <br /> SUBJECT : ABANDONMENT OF UNDERGROUND TANK LOCATED BEHIND <br /> THE PUBLIC SAFETY BUILDING. <br /> DATE : 06-08-88 <br /> Fire Marshal Raddigan and I have reviewed the plans for <br /> installation of a new underground tank and abandonment of the <br /> existing 18 ,000 gal , underground tank, located behind the <br /> Public Safety Building , at 210 West Elm Street . These plans <br /> were reviewed to determine if it would be allowable to <br /> abandon the existing tank in place in lieu of removal of the <br /> tank . <br /> It has been determined that the 18, 000 gal . existing tank <br /> may be abandoned in place as per the 1982 edition of the <br /> Uniform Fire Code and the 1987 edition of the National Fire <br /> Codes . We have reached this conclusion based on the <br /> following : <br /> 1 - The existing tank is not a standard installation due <br /> to its depth of 22 feet ± to the bottom of the tank. <br /> 2 - Removal in accordance with all applicable codes <br /> (i .e . ,CAL-OSHA) would require an unusually large <br /> excavation . <br /> 3 - Properly abandoning the tank in place will require <br /> that you meet the requirements outlined in NFPA <br /> standard 30 , appendix B, section 3 , paragraphs 1-3 <br /> (see attached . ) There is a recommended formula to <br /> be used for filling the tank. Fire marshal Raddigan <br /> is securing the mixture and will have it for you in <br /> the near future . <br /> Please call if you need further clarification or <br /> assistance . <br /> Larry F .
