Saalfield, City Attorney SUBJECT: VICE MAYOR REFERRAL OF PROPOSED ORDIN~E Please refer the following proposed ordinance to whichever committee you deem appropriate: 1) 'ABOVE-GROUNb STORAGE OF FLAMMABLE OR COMBUSTIBLE LIQUIDS. Background: As a result of a survey and discussions with representatives of the tank construction industry, the attached draft ordinance was created. I~ lays out those types of requirements that have been determined to yield a safe above-ground storage and refueling system. The draft ordinance allows above-ground fuel tanks of capacities no greater than 2,000 gallons. Larger above-ground fuel tanks are allowable in some areas of the city where building density is minimal. Above-ground fuel systems of greater capacities will be studied in the near future. The draft ordinance contains requirements that specifically relate to fire protection, such as the concrete encasement which allows the tank to be totally engulfed in flames for a one hour period without possibility of rupture or explosion. The ordinance also refers to application of environmental protection devices as per State law. Thank you. AJS/meg ORD-REFERRAL\ A/G-STRG.MEM Attachment cc: J.
