NR 433.02(1)(a)(a) Fossil fuel-fired steam electric plants of more than 250 million Btu per hour heat input, except for cogeneration units that supply 1/3 or less of their potential electric output capacity and 219,000 megawatt-hours or less actual electric output on an annual basis to any utility power distribution system for sale. NR 433.02(1)(i)(i) Municipal incinerators capable of charging more than 250 tons of refuse per day. NR 433.02(1)(v)(v) Fossil fuel boilers of more than 250 million Btu per hour heat input. NR 433.02(1)(w)(w) Petroleum storage and transfer facilities with a capacity exceeding 300,000 barrels. NR 433.02(2)(2) “Best available retrofit technology” or “BART” means an emission limitation based on the degree of reduction achievable through the application of the best system of continuous emission reduction for each visibility impairing pollutant which is emitted by a stationary source. The emission limitation shall be established on a case-by-case basis, taking into consideration the technology available, the costs of compliance, the energy and non-air quality environmental impacts of compliance, any pollution control equipment in use or in existence at the source, the remaining useful life of the source and the degree of improvement in visibility which may reasonably be anticipated to result from the use of the technology. NR 433.02(3)(3) “Deciview” means a metric for visibility impairment. A deciview is a haze index derived from calculated light extinction that is designed so that uniform changes in haziness correspond to uniform incremental changes in perception across the entire range of conditions, from pristine to highly impaired. The haze index in units of deciviews is calculated as follows: Haze index deciview =10 lne (beXt/10 Mm-1)
