(1) "Ash transport water" means water used in
				the hydraulic transport of either fly or bottom ash.
(2) "Average concentration" as it relates to
				chlorine discharge means the average of analyses made over a single period of
				chlorine release which does not exceed 2 hours.
(3) "Bottom ash" means the ash that drops out
				of the furnace gas stream in the furnace and in the economizer sections.
				Economizer ash is included when it is collected with bottom ash.
(4) "Chemical metal cleaning waste" means any
				wastewater resulting from the cleaning of any metal process equipment with
				chemical compounds, including, but not limited to, boiler tube
				cleaning.
(5) "Coal pile runoff"
				means the rainfall runoff from or through any coal storage pile.
(6) "Fly ash" means the ash that is carried
				out of the furnace by the gas stream and collected by mechanical collectors,
				electrostatic precipitators, fabric filters, or any combination of the 3.
				Economizer ash is included when it is collected with fly ash.
(7) "Free available chlorine" or "FAC" means
				the value obtained using the amperometric titration method for free available
				chlorine described in "Standard Methods for the Examination of Water and
				Wastewater", page 286 (15th edition, 1980).
Note: Copies of the above document are available for
				  inspection at the office of the department of natural resources, 101 S.
				  Webster, Madison; the secretary of state's office, and the office of the
				  legislative reference bureau, and may be obtained for personal use from the

(8) "Low volume
				waste sources" means, taken collectively as if from one source, wastewater from
				all sources except those for which specific limitations are otherwise
				established in s.
				NR 290.12.
				Low volume waste sources include wastewaters from wet scrubber air pollution
				control systems, ion exchange water treatment systems, water treatment
				evaporator blowdown, laboratory and sampling streams, boiler blowdown, floor
				drainage, cooling tower basin cleaning wastes and recirculating house service
				water systems. Sanitary and air conditioning wastes are specifically not
				included in this definition.
(9)
				"Metal cleaning wastes" means any wastewater resulting from the cleaning (with
				or without chemical cleaning compounds) of any metal process equipment
				including boiler tube cleaning, boiler fireside cleaning, and air preheater
				cleaning.
(10) "New source" for
				indirect dischargers means any building, structure, facility, or installation
				from which there is or may be a discharge of pollutants, the construction of
				which commenced on or after October 14, 1980; or for direct dischargers means
				any point source the construction of which commenced after November 19,
				1982.
(11) "No detectable amount"
				means any amount less than or equal to the level of pollutant detectability
				listed in 40 CFR Part 136.
(12)
				"Nonchemical metal cleaning waste" means any wastewater resulting from the
				cleaning of any metal process equipment without chemical compounds.
(13) "Once through cooling water" means water
				passed through the main cooling condensers in one or 2 passes for the purpose
				of removing waste heat.
(14) "126
				priority pollutants" means those pollutants listed in s.
				NR
				215.03.
(15) "Recirculated cooling water" means water
				which is passed through the main condensers for the purpose of removing waste
				heat, passed through a cooling device for the purpose of removing such heat
				from the water and then passed again, except for blowdown, through the main
				condenser.
(16) "10 year, 24 hour
				rainfall event" means a rainfall event with a probable recurrence interval of
				once in 10 years. Probable intensities of 10 year, 24 hour rainfall events are
				specified in s.
				NR
				205.05.
(17) "Total residual chlorine" or "TRC" or
				"total residual oxidants for intake water with bromides" means the value
				obtained using the amperometric method for total residual chlorine described in
				ch. NR 219.
