NR 440.70(14)(a)(a) Before using any equipment installed in compliance with the requirements of sub. (4), (5), (6), (7), (10) or (11), the owner or operator shall inspect the equipment for indications of potential emissions, defects or other problems that may cause the requirements of this section not to be met. Points of inspection shall include, but are not limited to, seals, flanges, joints, gaskets, hatches, caps and plugs.
NR 440.70(14)(b)(b) The owner or operator of each source that is equipped with a closed vent system and control device as required in sub. (7), other than a flare, is exempt from s. NR 440.08 and shall use Method 21 of 40 CFR part 60 Appendix A, incorporated by reference in s. NR 440.17, to measure the emission concentrations, using 500 ppm as the no detectable emission limit. The instrument shall be calibrated each day before using. The calibration gases shall be:
NR 440.70(14)(b)1.1. Zero air (less than 10 ppm of hydrocarbon in air) and
NR 440.70(14)(b)2.2. A mixture of either methane or n-hexane and air at a concentration of approximately, but less than, 10,000 ppm methane or n-hexane.
NR 440.70(14)(c)(c) The owner or operator shall conduct a performance test initially and at other times as requested by the department, using the test methods and procedures in s. NR 440.18 (6) to determine compliance of flares.
NR 440.70(14)(d)(d) After installing the control equipment required to meet sub. (11) (a) to (g) or whenever sources that have ceased to treat refinery wastewater for a period of 1 year or more are placed back into service, the owner or operator shall determine compliance with the standards in sub. (11) (a) to (g) as follows:
NR 440.70(14)(d)1.1. The maximum gap widths and maximum gap areas between the primary seal and the separator wall and between the secondary seal and the separator wall shall be determined individually within 60 calendar days of the initial installation of the floating roof and introduction of refinery wastewater or 60 calendar days after the equipment is placed back into service using the following procedure when the separator is filled to the design operating level and when the roof is floating off the roof supports.
NR 440.70(14)(d)1.a.a. Measure seal gaps around the entire perimeter of the separator in each place where a 0.32 cm (0.125 in) diameter uniform probe passes freely, without forcing or binding against seal, between the seal and the wall of the separator and measure the gap width and perimetrical distance of each such location.
NR 440.70(14)(d)1.b.b. That total surface area of each gap described in subd. 1. a. shall be determined by using probes of various widths to measure accurately the actual distance from the wall to the seal and multiplying each such width by its respective perimetrical distance.
NR 440.70(14)(d)1.c.c. Add the gap surface area of each gap location for the primary seal and the secondary seal individually, divide the sum for each seal by the nominal perimeter of the separator basin and compare each to the maximum gap area as specified in sub. (11).
NR 440.70(14)(d)2.2. The gap widths and total gap area shall be determined using the procedure in subd. 1. according to the following frequency:
NR 440.70(14)(d)2.a.a. For primary seals, once every 5 years.
NR 440.70(14)(d)2.b.b. For secondary seals, once every year.
NR 440.70(15)(15)Recordkeeping requirements.
NR 440.70(15)(a)(a) Each owner or operator of a facility subject to the provisions of this section shall comply with the recordkeeping requirements of this subsection. All records shall be retained for a period of 2 years after being recorded unless otherwise noted.
NR 440.70(15)(b)(b) For individual drain systems subject to sub. (4), the location, date and corrective action shall be recorded for each drain when the water seal is dry or otherwise breached, when a drain cap or plug is missing or improperly installed or other problem is identified that could result in VOC emissions, as determined during the initial and periodic visual or physical inspection.
NR 440.70(15)(c)(c) For junction boxes subject to sub. (4), the location, date and corrective action shall be recorded for inspections required by sub. (4) (f) to (i) when a broken seal, gap or other problem is identified that could result in VOC emissions.
NR 440.70(15)(d)(d) For sewer lines subject to subs. (4) and (5) (e), the location, date and corrective action shall be recorded for inspections required by sub. (4) (j) to (n) and (10) (e) to (g) when a problem is identified that could result in VOC emissions.
NR 440.70(15)(e)(e) For oil-water separators subject to sub. (5), the location, date and corrective action shall be recorded for inspections required by sub. (5) (a) when a problem is identified that could result in VOC emissions.
NR 440.70(15)(f)(f) For closed vent systems subject to sub. (7) and completely closed drain systems subject to sub. (10), the location, date and corrective action shall be recorded for inspections required by sub. (7) (e) to (i) during which detectable emissions are measured or a problem is identified that could result in VOC emissions.
NR 440.70(15)(g)(g) If an emission point cannot be repaired or corrected without a process unit shutdown, the expected date of a successful repair shall be recorded.
NR 440.70(15)(g)1.1. The reason for the delay as specified in sub. (8) shall be recorded if an emission point or equipment problem is not repaired or corrected in the specified amount of time.
NR 440.70(15)(g)2.2. The signature of the owner or operator, or designee, whose decision it was that repair could not be effected without refinery or process shutdown shall be recorded.
NR 440.70(15)(g)3.3. The date of successful repair or corrective action shall be recorded.
NR 440.70(15)(h)(h) A copy of the design specifications for all equipment used to comply with the provisions of this section shall be kept for the life of the source in a readily accessible location.
NR 440.70(15)(i)(i) The following information pertaining to the design specifications shall be kept:
NR 440.70(15)(i)1.1. Detailed schematics and piping and instrumentation diagrams.
NR 440.70(15)(i)2.2. The dates and descriptions of any changes in the design specifications.
NR 440.70(15)(j)(j) The following information pertaining to the operation and maintenance of closed drain systems and closed vent systems shall be kept in a readily accessible location:
