Pi is the glass pull rate at interval “i”, Mg/hr (ton/hr)
Ls is the line speed, m/min (Ft/min)
Wm is the trimmed mat width, m (ft)
M is the mat gram weight, g/m2 (lb/ft2)
LOI is the loss on ignition, weight percent
K’ is the conversion factor, 6 × 10-5 (min-Mg)/(hr-g) [3 × 10-2 (min-ton)/(hr-lb)]
NR 440.69(6)(c)3.a.a. ASTM Standard Test Method D2584-94, incorporated by reference in s. NR 440.17 (2) (a) 32., shall be used to determine the LOI for each run.
NR 440.69(6)(c)3.b.b. Line speed (Ls) trimmed mat width (Wm) and mat gram weight (M) shall be determined for each run from the process information or from direct measurements.
NR 440.69(6)(d)(d) To comply with sub. (5) (d), the owner or operator shall record measurements as required in sub. (5) (a) and (b) using the monitoring devices in sub. (4) (a) and (b) during the particulate matter runs.

NR 440.70(1)(a)(a)
NR 440.70(1)(a)1.1. The provisions of this section apply to affected facilities located in petroleum refineries for which construction, modification or reconstruction is commenced after May 4, 1987.
NR 440.70(1)(a)2.2. An individual drain system is a separate affected facility.
NR 440.70(1)(a)3.3. An oil-water separator is a separate affected facility.

NR 440.70(1)(b)(b) Notwithstanding the provisions of s. NR 440.14 (5) (b), the construction or installation of a new individual drain system shall constitute a modification to an affected facility described in par. (a) 4. For purposes of this paragraph, a new individual drain system shall be limited to all process drains and the first common junction box.
NR 440.70(2)(2)Definitions. As used in this section, all terms not defined herein shall have the meaning given them in s. NR 440.02 and the following terms shall have the specific meanings given them.
NR 440.70(2)(a)(a) “Active service” means that a drain is receiving refinery wastewater from a process unit that will continuously maintain a water seal.
NR 440.70(2)(b)(b) “Aggregate facility” means an individual drain system together with ancillary downstream sewer lines and oil-water separators, down to and including the secondary oil-water separator, as applicable.
NR 440.70(2)(c)(c) “Catch basin” means an open basin which serves as a single collection point for stormwater runoff received directly from refinery surfaces and for refinery wastewater from process drains.
NR 440.70(2)(d)(d) “Closed vent system” means a system that is not open to the atmosphere and that is composed of piping, connections and, if necessary, flow inducing devices that transport gas or vapor from an emission source to a control device. If gas or vapor from regulated equipment is routed to a process, e.g., to a petroleum refinery fuel gas system, the process is not considered a closed vent system and is not subject to the closed vent system standards.
NR 440.70(2)(e)(e) “Completely closed drain system” means an individual drain system that is not open to the atmosphere and is equipped and operated with a closed vent system and control device complying with the requirements of sub. (7).
NR 440.70(2)(f)(f) “Control device” means an enclosed combustion device, vapor recovery system or flare.
NR 440.70(2)(g)(g) “Fixed roof” means a cover that is mounted to a tank or chamber in a stationary manner and which does not move with fluctuations in wastewater levels.
NR 440.70(2)(h)(h) “Floating roof” means a pontoon-type or double-deck type cover that rests on the liquid surface.
NR 440.70(2)(i)(i) “Gas-tight” means operated with no detectable emissions.
NR 440.70(2)(j)(j) “Individual drain system” means all process drains connected to the first common downstream junction box. The term includes all such drains and common junction box, together with their associated sewer lines and other junction boxes, down to the receiving oil-water separator.
