The vinyl chloride monitoring system shall be operated according to a program developed by the plant owner or operator. The owner or operator shall submit a description of the program to the Technical Secretary within 45 days of November 6, 1988.

Approval of a program will be granted by the Technical Secretary provided he finds:

(I) The location and number of points to be monitored and the frequency of monitoring provided for in the program are acceptable when they are compared with the number of pieces of equipment in vinyl chloride service and size and physical layout of the plant.
(II) It contains a definition of leak which is acceptable when compared with the background concentrations of vinyl chloride in the areas of the plant to be monitored by the vinyl chloride monitoring system. Measurements of background concentrations of vinyl chloride in the areas of the plant to be monitored by the vinyl chloride monitoring system are to be included with the description of the program. The definition of leak for a given plant may vary among the different areas within the plant and is also to change over time as background concentrations in the plant are reduced.
(III) It contains an acceptable plan of action to be taken when a leak is detected.
(IV) It provides for an acceptable calibration and maintenance schedule for the vinyl chloride monitoring system and portable hydrocarbon detector. For the vinyl chloride monitoring system, a daily span check is to be conducted with a concentration of vinyl chloride equal to the concentration defined as a leak according to item (c)8.(i)(II) of this paragraph. The calibration is to be done with either:
I. A calibration gas mixture prepared from the gases specified in sections 5.2.1. and 5.2.2. of Test Method 106 and in accordance with section 7.1 of Test Method 106 (as specified in the Federal Register, Volume 41, Number 205, of October 21, 1976, beginning on page 46569 as Method 106, as amended in the Federal Register, Volume 41, Number 234, Friday, December 3, 1976, and the Federal Register, Volume 42, Number 109, of June 7, 1977), or
II. A calibration gas cylinder standard containing the appropriate concentration of vinyl chloride. The gas composition of the calibration gas cylinder standard is to have been certified by the manufacturer. The manufacturer must have recommended a maximum shelf life for each cylinder so that the concentration does not change greater than +5 percent from the certified value. The date of gas cylinder preparation, certified vinyl chloride concentration, and recommended maximum shelf life must have been affixed to the cylinder before shipment from the manufacturer to the buyer. If a gas chromatograph is used as the vinyl chloride monitoring system, these gas mixtures may be directly used to prepare a chromatograph calibration curve as described in section 7.3 of Test Method 106. The requirements in section 5.2.3.1. and 5.2.3.2. of Test Method 106 for certification of cylinder standards and for establishment and verification of calibration standards are to be followed.
(ii) For each process unit subject to this rule a formal leak detection and repair program shall be implemented consistent with rule 1200-03-11-.06, except as provided in subpart (iii) of subparagraph (c)8. of this paragraph.

If an instrument reading of 10,000 ppm or greater is measured, a leak is detected. The leak percentage shall be determined by dividing the number of valves in VOC service for which leaks are detected by the number of tested valves in VOC service.
(III) If a leak is detected, it shall be repaired in accordance with 1200-03-11-.06(3)(g) 4. and 5.
(IV) The results of the performance test shall be submitted in writing to the Technical Secretary in the first quarterly report following the performance test as part of the reporting requirements of paragraph 1200-03-11-.05(11).
(V) Any process unit in which the percentage of leaking valves is found to be greater than 2.0 percent according to the performance test prescribed in item (II) of subpart (6)(c)8.(ii) of this rule must comply with all provisions of rule 1200-03-11-.06 within 90 days.

(h) Measurement of Vinyl Chloride
1. Each piece of equipment within a process unit that can responsibly contain equipment in vinyl chloride service is presumed to be in vinyl chloride service unless an owner or operator demonstrates that the piece of equipment is not in vinyl chloride service. For a piece of equipment to be considered not in vinyl chloride service, it must be determined that the percent vinyl chloride content can be reasonably expected not to exceed 10 percent by weight for liquid streams or contained liquid volumes and 10 percent by volume for gas streams or contained gas volumes, which also includes gas volumes above liquid streams or contained liquid volumes. For purposes of determining the percent vinyl chloride content of the process fluid that is contained in or contacts equipment, procedures that conform to the methods described in ASTM Method D-2267 shall be used. (Note: All references to ASTM in this rule refers to the American Society for Testing Materials. Copies of methods are available for purchase by writing to ASTM , 1916 Race Street, Philadelphia, PA 19103 or by writing to the Tennessee Division of Air Pollution Control, 701 Broadway, 4th Floor, Customs House, Nashville, TN 37219. Be sure and specify which method is desired).
2.
(i) An owner or operator may use engineering judgment rather than the procedures in part (h)1. of this paragraph to demonstrate that the percent vinyl chloride content does not exceed 10 percent by weight for liquid streams and 10 percent by volume for gas streams, provided that the engineering judgment demonstrates that the vinyl chloride content clearly does not exceed 10 percent. When an owner or operator and the Technical Secretary do not agree on whether a piece of equipment is not in vinyl chloride service, however, the procedures in part (h)1. of this paragraph shall be used to resolve the disagreement.
(ii) If an owner or operator determines that a piece of equipment is in vinyl chloride service, the determination can be revised only after following the procedures in part (h)1. of this paragraph.
3. Samples used in determining the percent vinyl chloride content shall be representative of the process fluid that is contained in or contacts the equipment.

(b) The vinyl chloride monitoring system(s) used to meet the requirement in subparagraph (a) of this paragraph is to be a device which obtains air samples from one or more points on a continuous sequential basis and analyzes the samples with gas chromotography, or, if the owner or operator assumes that all hydrocarbons measured are vinyl chloride with infrared spectrophotometry, flame ion detection, or an equivalent or alternative method. The vinyl chloride monitoring system used to meet the requirements in subpart (6)(c)8.(i) of this rule may be used to meet the requirements of this paragraph.
(c) A daily span check is to be conducted for each vinyl chloride monitoring system used. For all of the emission sources listed in subparagraph (a) of this paragraph, except the one for which an emission limit is prescribed in subparagraph (3)(c) of this rule, the daily span check is to be conducted with a. concentration of vinyl chloride equal to 10 ppm. For the emission source for which an emission limit is prescribed in subparagraph (3)(c) of this rule the daily span check is to be conducted with a concentration of vinyl chloride which is determined to be equivalent to the emission limit for that source based on the emission test required by paragraph (8) of this rule. The calibration is to be done with either:
1. A calibration gas mixture prepared from the gases specified in sections 5.2.1 and 5.2.3 of Test Method 106 and in accordance with section 7.1 of Test Method 106 (Method 106 as referenced in part (8)(g)1. of this rule), or
2. A calibration gas cylinder standard containing the appropriate concentration of vinyl chloride. The gas composition of the calibration gas cylinder standard is to have been certified by the manufacturer. The manufacturer must have recommended a maximum shelf life for each cylinder so that the concentration does not change greater than +5 percent from the certified value. The date of gas cylinder preparation, certified vinyl chloride concentration and recommended maximum shelf life must have been affixed to the cylinder before shipment from the manufacturer to the buyer. If a gas chromatograph is used as the vinyl chloride monitoring system, these gas mixtures may be directly used to prepare a chromatograph calibration curve as described in section 7.3 of Test Method 106. The requirements in sections 5.2.3.1 and 5.2.3.2 of Test Method 106 for certification of cylinder standards and for establishment and verification of calibration standards are to be followed.

(d) When exhaust gas(es), having emission limits that are subject to the requirement of subparagraph (a) of this paragraph, are emitted to the atmosphere without passing through the control system and required vinyl chloride monitoring system, the vinyl chloride content of the emission shall be calculated (in units of each applicable emission limit) by best practical engineering judgment based on the discharge duration and known VC concentrations in the affected equipment as determined in accordance with Test Method 106 or other acceptable method.
(e) For each 3-hour period, the vinyl chloride content of emissions subject to the requirements of subparagraphs (a) and (d) of this paragraph shall be averaged (weighted according to the proportion of time that emissions were continuously monitored and that emissions bypassed the continuous monitor) for purposes of reporting excess emissions under part 1200-03-11-.05(11)(c) 1.
(f) For each vinyl chloride emission to the atmosphere determined in accordance with subparagraph (e) of this paragraph to be in excess of the applicable emission limits, the owner or operator shall record the identify of the source(s), the date, time, and duration of the excess emission, the cause of the excess emission, and the approximate total vinyl chloride loss during the excess emission, and the method used for determining the vinyl chloride loss.
