3) If steam-jet ejectors are used as vacuum producers and a high viscosity product is being produced using multiple end finishers, maintain an ethylene glycol concentration in the cooling tower at or below 6.0% by weight, averaged on a daily basis over a rolling 14-day period of operating days.
NR 440.647(3)(d)(d) Closed vent systems and control devices used to comply with this section shall be operated at all times when emissions may be vented to them. NR 440.647(3)(e)(e) Vent systems that contain valves that could divert a vent stream from a control device shall have car-sealed opened all valves in the vent system from the emission source to the control device and car-sealed closed all valves in vent system that would lead the vent stream to the atmosphere, either directly or indirectly, bypassing the control device. NR 440.647(4)(a)(a) Each owner or operator of an affected facility subject to the provisions of this section shall comply with the requirements specified in s. NR 440.62 (3) as soon as practicable, but no later than 180 days after initial startup, except that indications of liquids dripping from bleed ports in existing pumps in light liquid service are not considered to be a leak as defined in s. NR 440.62 (3) (b) 2. b. For purposes of this standard, a “bleed port” is a technologically-required feature of the pump whereby polymer fluid used to provide lubrication, cooling, or both, of the pump shaft exits the pump, thereby resulting in a visible leak of fluid. This exemption expires when the existing pump is replaced or reconstructed. NR 440.647(4)(c)(c) An owner or operator may apply to the administrator for a determination of equivalency for any means of emission limitation that achieves a reduction in emissions of VOC at least equivalent to the reduction in emissions of VOC achieved by the controls required in this section. In doing so, the owner or operator shall comply with requirements specified in 40 CFR 60.484, as in effect on July 1, 1994. NR 440.647(4)(d)(d) Each owner or operator subject to the provisions of this section shall comply with the provisions specified in s. NR 440.62 (6) except an owner or operator may use the following provision in addition to s. NR 440.62 (6) (e). Equipment is in light liquid service if the percent evaporated is greater than 10% at 150°C (302°F) as determined by ASTM D86-96, incorporated by reference in s. NR 440.17 (2) (a) 7. NR 440.647(5)(a)(a) Whenever a particular item of monitoring equipment specified in this subsection is to be installed, the owner or operator shall install, calibrate, maintain and operate according to manufacturer’s specifications that item as follows: NR 440.647(5)(a)1.1. A temperature monitoring device to measure and record continuously the operating temperature to within 1% (relative to degrees Celsius) or ±0.5°C (±0.9°F), whichever is greater. NR 440.647(5)(a)2.2. A flame monitoring device, such as a thermocouple, an ultra-violet sensor, an infrared beam sensor or similar device to indicate and record continuously whether a flare or pilot light flame is present, as specified. NR 440.647(5)(a)3.3. A flow monitoring indicator to indicate and record whether or not flow exists at least once every 15 minutes. NR 440.647(5)(a)4.4. An organic monitoring device, based on a detection principle such as infrared, photoionization or thermal conductivity, to indicate and record continuously the concentration level of organic compounds. NR 440.647(5)(a)5.5. A specific gravity monitoring device to measure and record continuously to within 0.02 specific gravity unit. NR 440.647(5)(b)(b) The owner or operator shall install, as applicable, the monitoring equipment for the control means used to comply with sub. (3) except sub. (3) (a) 1. a. 4) as follows: NR 440.647(5)(b)1.a.a. For a noncatalytic incinerator, a temperature monitoring device shall be installed in the firebox. NR 440.647(5)(b)1.b.b. For a catalytic incinerator, temperature monitoring devices shall be installed in the gas stream immediately before and after the catalytic bed. NR 440.647(5)(b)2.a.a. A flame monitoring device shall be installed to indicate the presence of a flare flame or a flame for each pilot light, if the flare is used to comply with sub. (3) (a) 1. including those flares controlling both continuous and intermittent emissions. NR 440.647(5)(b)2.b.b. A thermocouple or equivalent monitoring device to indicate the presence of a flame at each pilot light, if used to comply with sub. (3) (a) 2. NR 440.647(5)(b)3.a.a. If the boiler or process heater has a heat input design capacity of less than 150 million Btu/hr, a temperature monitoring device shall be installed between the radiant section and the convection zone for watertube boilers and between the furnace, combustion zone, and the firetubes for firetube boilers. NR 440.647(5)(b)3.b.b. If the boiler or process heater has a heat input design capacity of 150 million Btu/hr or greater, records to indicate the periods of operation of the boiler or process heater shall be maintained. The records shall be readily available for inspection. NR 440.647(5)(b)4.a.a. A temperature monitoring device and a specific gravity monitoring device for the scrubber liquid shall be installed; or NR 440.647(5)(b)4.b.b. An organic monitoring device shall be installed at the outlet of the absorber.
