Current through Vol. 24-12, July 15, 2024
Rule 801
(1) As used
				in this rule:
(a) "Btu" means a British
				thermal unit
(b) "Capacity factor"
				means either of the following:
(i) The ratio
				of a unit's actual annual electric output, expressed in megawatt hour, to the
				unit's nameplate capacity times 8,760 hours.
(ii) The ratio of a unit's annual heat input,
				expressed in million Btu or equivalent units of measure, to the unit's maximum
				design heat input, expressed in million Btus per hour or equivalent units of
				measure, times 8,760 hours.
(c) "Electricity-generating utility unit"
				means a unit that produces electricity for sale.
(d) "Fossil fuel-fired" means the actual
				combustion of fossil fuel, which includes coke oven gas, alone or in
				combination with any other fuel, where either of the following quantities are
				greater than 50% on an annual basis:
(i) Sum
				of the mass of fossil fuels combusted divided by the total mass of all fuels
				combusted.
(ii) Sum of the annual
				heat inputs for fossil fuels combusted divided by the total heat input for all
				fuels combusted. Annual heat inputs are on a Btu basis.
(e) "Low-NOx burners" means 1 of several
				developing combustion technologies used to minimize the formation of emissions
				of nitrogen oxides. As applicable to cement kilns, low-NOx burners means a type
				of cement kiln burner system designed to minimize (NOx) formation by
				controlling flame turbulence, delaying fuel/air mixing, and establishing
				fuel-rich zones for initial combusting, that for firing of solid fuel in the
				burning end zone of a kiln's main burner includes an indirect firing system or
				comparable technique for the main burner in the burning end zone of the kiln to
				minimize the amount of primary air supplied through the burner. In an indirect
				firing system, 1 air stream is used to convey pulverized fuel from the grinding
				equipment and at least 1 or more other air streams are used to supply primary
				air to the burning end zone kiln burner of the kiln with the pulverized fuel,
				with intermediate storage of the fuel, and necessary safety and explosion
				prevention systems associated with the intermediate storage of fuel.
(f) "Mid-kiln system firing" means the
				secondary firing in a kiln system by injecting solid fuel at an intermediate
				point in the kiln system using a specially designed heat injection mechanism
				for the purpose of decreasing NOx emissions through coal burning part of the
				fuel at lower temperatures and reducing conditions at the fuel injection point
				that may destroy some of the NOx.
(g) "Non-SIP call source" means any
				stationary source of NOx emissions that is not a NOx budget source subject to
				R 336.1802.
(h) "NOx" means oxides of nitrogen.
(i) "Ozone control period" means the period
				of May 1 through September 30.
(j)
				"Peaking unit" means an electricity-generating utility unit that has an average
				capacity factor of not more than 10% during the previous 3 calendar years and a
				capacity factor of not more than 20% in each of those calendar years.
(k) "Process heater" means any combustion
				equipment which is fired by a liquid fuel or a gaseous fuel, or both, and which
				is used to transfer heat from the combustion gases to a process fluid,
				superheated steam, or water.
(l)
				"SIP" means state implementation plan.
(m) "Unit" means a fossil fuel-fired
				combustion device.
