Section NR 463.03 - Nomenclature, units and abbreviations

The definitions contained in s. NR 400.03 apply to the abbreviations and symbols of units of measure used in this subchapter. In addition, the nomenclature used in this subchapter has the following meaning:

(1) AMR is the allowable mass emission rate from each type of affected source subject to the same emission limitation in milligrams per hour (mg/hr).
(2) AMRsys is the allowable mass emission rate from affected sources controlled by an add-on air pollution control device controlling emissions from multiple sources in mg/hr.
(3) CMP is composite mesh-pad, a control technique.
(4) EL is the applicable emission limitation from s. NR 463.04 in milligrams per dry standard cubic meter (mg/dscm).
(5) IAtotal is the sum of all inlet duct areas from both affected sources and sources not affected by this subchapter in meters squared.
(6) IDAi is the total inlet area for all ducts associated with affected sources in meters squared.
(7) IDAi,a is the total inlet duct area for all ducts conveying chromic acid from each type of affected source performing the same operation, or each type of affected source subject to the same emission limitation in meters squared.
(8) lbf is pound-force, the unit of force in the English system.
(9) PBS is packed-bed scrubber, a control technique.
(10) VR is the total of ventilation rates for each type of affected source subject to the same emission limitation in dry standard cubic meters per minute (dscm/min).
(11) VRinlet is the total ventilation rate from all inlet ducts associated with affected sources in dscm/min.
(12) VRinlet,a is the total ventilation rate from all inlet ducts conveying chromic acid from each type of affected source performing the same operation, or each type of affected source subject to the same emission limitation in dscm/min.
(13) VRtot is the average total ventilation rate for the 3 test runs as determined at the outlet by testing using Method 306 of Appendix A of 40 CFR part 63, incorporated by reference in s. NR 484.04, in dscm/min.
