The following topics are discussed: <br /> 1. Definitions of farm tanks and home heating oil tanks; <br /> 2. Examples of exempt tanks; <br /> 3. Conditions under which an exempt tank becomes a regulated tank; and <br /> 4. Tank owner responsibilities if an exempt tank becomes a regulated tank. <br /> 1) Definition of Farm Tanks and Home Heating Oil Tanks (Section 2611 CCR) <br /> a. "Farm tank" means any one tank or a combination of manifolded tanks that 1) are located on a farm; <br /> and 2) hold no more than 1,100 gallons of motor vehicle fuel [MVF] which are used primarily for <br /> agricultural purposes and are not held for resale. <br /> b. "Heating oil tank" means a tank located on a farm or at a personal residence and which holds no more <br /> than 1,100 gallons of home heating oil which is used consumptively at the premises where the tank is <br /> located. <br /> 2) Examples of Exempt Tanks (Section 2621(a) CCR) <br /> All farm tanks and home heating oil tanks which meet the criteria specified in (a) or(b) above are <br /> exempt from state UST regulations. Consequently, installation, operating, and closure requirements do <br /> not apply to these tanks. For example, home heating oil tanks at homes which have converted to <br /> electricity or natural gas for heating purposes are exempt as long as they are not used for a non-exempt <br /> purpose. Also, farm tanks with a capacity of 1,100 gallons or less which store motor vehicle fuel for <br /> agricultural purposes are exempt as long as they are not used for a non-exempt purpose. However, the <br /> State and Regional Water Board's authority, under Section 13304 of the California Water Code,to <br /> re wire clean a or other ollution reventon measures remains unimpaired if releases from such tanks <br /> threaten water quality. <br /> 3) Conditions Under Which an Exempt Tank Becomes a Regulated Tank <br /> (Section 2621(c) CCR) <br /> An exempt UST may become regulated if a condition allowing its exemption changes. A change in <br /> exemption status can come from any of the following: <br /> a. Property loses its status as a "farm".
