NR 440.62(2)(hm)(hm) “Fuel gas system” means the offsite and onsite piping and flow and pressure control system that gathers gaseous streams generated by onsite operations, may blend them with other sources of gas, and transports the gaseous stream for use as fuel gas in combustion devices or in-process combustion equipment, such as furnaces and gas turbines, either singly or in combination. NR 440.62(2)(hs)(hs) “Hard-piping” means pipe or tubing that is manufactured and properly installed using good engineering judgment and standards such as ASME B31.3, Process Piping (available from the American Society of Mechanical Engineers, PO Box 2900, Fairfield, NJ 07007-2900). NR 440.62(2)(i)(i) “In gas/vapor service” means that the piece of equipment contains process fluid that is in the gaseous state at operating conditions. NR 440.62(2)(j)(j) “In heavy liquid service” means that the piece of equipment is not in gas vapor service or in light liquid service. NR 440.62(2)(k)(k) “In light liquid service” means that the piece of equipment contains a liquid that meets the conditions specified in sub. (6) (e). NR 440.62(2)(ke)(ke) “In-situ sampling systems” means nonextractive samplers or in-line samplers. NR 440.62(2)(km)(km) “In-vacuum service” means that equipment is operating at an internal pressure which is at least 5 kilopascals (kPa) (0.7 psia) below ambient pressure. NR 440.62(2)(ks)(ks) “In VOC service” means that the piece of equipment contains or contacts a process fluid that is at least 10% VOC by weight. (The provisions of sub. (6) (d) specify how to determine that a piece of equipment is not in VOC service.) NR 440.62(2)(L)(L) “Liquids dripping” means any visible leakage from the seal including spraying, misting, clouding and ice formation. NR 440.62(2)(m)(m) “Open-ended valve or line” means any valve, except safety relief valves, having one side of the valve seat in contact with process fluid and one side open to the atmosphere, either directly or through open piping. NR 440.62(2)(n)(n) “Pressure release” means the emission of materials resulting from system pressure being greater than set pressure of the pressure relief device. NR 440.62(2)(o)(o) “Process improvement” means routine changes made for safety and occupational health requirements, for energy savings, for better utility, for ease of maintenance and operation, for correction of design deficiencies, for bottleneck removal, for changing product requirements, or for environmental control. NR 440.62(2)(p)(p) “Process unit” means components assembled to produce, as intermediate or final products, one or more of the chemicals listed in Table A of sub. (10). A process unit can operate independently if supplied with sufficient feed or raw materials and sufficient storage facilities for the product. NR 440.62(2)(q)(q) “Process unit shutdown” means a work practice or operational procedure that stops production from a process unit or part of a process unit. An unscheduled work practice or operational procedure that stops production from a process unit or part of a process unit for less than 24 hours is not a process unit shutdown. The use of spare equipment and technically feasible bypassing of equipment without stopping production are not process unit shutdowns. NR 440.62(2)(r)(r) “Quarter” means a 3-month period; the first quarter concludes on the last full month during the 180 days following initial startup. NR 440.62(2)(s)(s) “Repaired” means that equipment is adjusted, or otherwise altered, in order to eliminate a leak as indicated by one of the following: an instrument reading of 10,000 ppm or greater, indication of liquids dripping, or indication by a sensor that a seal or barrier fluid system has failed. NR 440.62(2)(t)(t) “Replacement cost” means the capital needed to purchase all the depreciable components in a facility. NR 440.62(2)(tm)(tm) “Sampling connection system” means an assembly of equipment within a process unit used during periods of representative operation to take samples of the process fluid. Equipment used to take nonroutine grab samples is not considered a sampling connection system. NR 440.62(2)(u)(u) “Sensor” means a device that measures a physical quantity such as temperature, pressure, flow rate, pH, or liquid level. NR 440.62(2)(w)(w) “Synthetic organic chemicals manufacturing industry” means the industry that produces, as intermediates or final products, one or more of the chemicals listed in Table A of sub. (10). NR 440.62(2)(y)(y) “Volatile organic compounds” or “VOC” means, for the purpose of this section, any reactive organic compounds as defined in s. NR 440.02 (35). NR 440.62(3)(a)1.1. Each owner or operator subject to the provisions of this section shall demonstrate compliance with the requirements of pars. (a) to (j) or sub. (1) (e) for all equipment within 180 days of initial startup. NR 440.62(3)(a)2.2. Compliance with pars. (a) to (j) will be determined by review of records and reports, review of performance test results and inspection using the methods and procedures specified in sub. (6). NR 440.62(3)(a)3.3. An owner or operator may apply to the administrator for a determination of equivalence of a means of emission limitation to the requirements of par. (b), (c), (e), (f), (g), (h) or (j) under 40 CFR 60.484, as in effect on July 1, 1994. If the administrator makes a determination that a means of emission limitation is at least equivalent, the owner or operator shall notify the department of that determination and comply with its requirements rather than the requirements of par. (b), (c), (e), (f), (g), (h) or (j).
