Rule 121. As used in these rules:

(a) "Uncontrolled emissions" means those emissions expected to occur without control equipment, unless such control equipment is, aside from air pollution control requirements, vital to production of the normal product of the process or to its normal operation. Annual uncontrolled emissions shall be based upon the maximum annually rated capacity of the process or process equipment, unless the process or process equipment is subject to legally enforceable permit conditions or orders which limit the operating rate or the hours of operation, or both. Legally enforceable permit conditions or orders on the type or amount of materials combusted or processed shall be used in determining the uncontrolled emissions rate of a process or process equipment.
(b) "Unsafe-to-monitor component" means a component which, if monitored, would expose monitoring personnel to immediate danger. This definition includes, during the period of November 1 through March 31, a component which is located outside a building and which can only be monitored by elevating the monitoring personnel more than 6 feet above ground level.
(c) "Used oil" means any oil that has been refined from crude oil, or any synthetic oil, that has been used and that, as a result of the use, is contaminated by physical or chemical impurities.
