Section NR 449.09 - Emission tests(1) Unless a waiver of emission testing is obtained from the department, each owner or operator of a source to which this section applies on which construction or modification commenced after February 1, 1984 shall test emissions from the source within 90 days of startup.(2) The department shall be notified at least 30 days prior to a stack or performance test to afford the department the opportunity to have a representative present to witness the testing procedures.(3) Any emission test shall be conducted while the equipment being tested is operating at the maximum production rate at which the equipment will be operated and under other relevant conditions as may be specified by the department based on the representative performance of the source.(4) When at all possible, each sample shall be analyzed within 24 hours, but in no case in excess of 72 hours of sample collection. Vinyl chloride emissions shall be determined within 30 days after the emission test. The owner or operator shall report the determinations to the department by registered letter dispatched before the close of the next business day following the determination.(5) The owner or operator shall retain at the plant and make available, upon request, for inspection by a department representative, for a minimum of 2 years, records of emission test results and other data needed to determine emissions.(6) Unless otherwise specified, the owner or operator shall use Methods of 40 CFR part 61, Appendix B, incorporated by reference in s. NR 484.04(23), for each test as required by pars. (a) to (e) unless an equivalent method or an alternative method has been approved by the department. If the department finds reasonable grounds to dispute the results obtained by an equivalent or alternative method, the department may require the use of a reference method. If the results of the reference and equivalent or alternative methods do not agree, the results obtained by the reference method prevail, and the department may notify the owner or operator that approval of the method previously considered to be equivalent or alternative is withdrawn. (a) Method 106 of 40 CFR part 61, Appendix B, incorporated by reference in s. NR 484.04, shall be used to determine the vinyl chloride emissions from any source for which an emission limit is prescribed in ss. NR 449.04(1) or (2), 449.05(1), 449.06(1) (a), (2), (3) or (4), or from any control system to which reactor emissions are required to be ducted in s. NR 449.06(1) (b) or to which fugitive emissions are required to be ducted in s. NR 449.07(2) (a) 2., (b), (e), (f) 2. or (i) 2. 1. For each run, one sample shall be collected. The sampling site shall be at least 2 stack or duct diameters downstream and one-half diameter upstream from any flow disturbance such as a bend, expansion, contraction or visible flame. For a rectangular cross section an equivalent diameter shall be determined from the following equation: equivalent diameter = 2 (length)(width) / length + width
The sampling point in the duct shall be at the centroid of the cross section. The sample shall be extracted at a rate proportional to the gas velocity at the sampling point. The sample shall be taken over a minimum of one hour, and shall contain a minimum volume of 50 liters corrected to standard conditions.
2. Each emission test shall consist of 3 runs. For the purpose of determining emissions, the average of results of all runs shall apply. The average shall be computed on a time weighted basis.3. For gas streams containing more than 10% oxygen the concentration of vinyl chloride as determined by Method 106 shall be corrected to 10% oxygen (dry basis) for determination of emissions by using the following equation: See Image
4. For those emission sources where the emission limit is prescribed in terms of mass rather than concentration, mass emissions in kilograms per 100 kilograms product shall be determined by using the following equation: See Image
(b) Method 107 of 40 CFR part 61, Appendix B, incorporated by reference in s. NR 484.04(23), shall be used to determine the concentration of vinyl chloride in each inprocess wastewater stream for which an emission limit is prescribed in s. NR 449.07(2) (i) 1.(c) Where a stripping operation is used to attain the emission limit in s. NR 449.06(5), emissions shall be determined using Method 107 of 40 CFR part 61, Appendix B, incorporated by reference in s. NR 484.04(3), as follows: 1. The number of strippers and samples and the types and grades of resin to be sampled shall be determined by the department for each individual plant at the time of the test based on the plant's operation.2. Each sample shall be taken immediately following the stripping operation.3. The corresponding quantity of material processed by each stripper shall be determined on a dry solids basis and by a method submitted to and approved by the department.4. At the prior request of the department, the owner or operator shall provide duplicates of the samples required in subd. 1.(d) Where control technology other than or in addition to a stripping operation is used to attain the emission limit in s. NR 449.06(5), emissions shall be determined as follows: 1. Method 106 of 40 CFR part 61, Appendix B, incorporated by reference in s. NR 484.04(23), shall be used to determine atmospheric emissions from all of the process equipment simultaneously. The requirements of par. (a) shall be met. 2. Method 107 of 40 CFR part 61, Appendix B, incorporated by reference in s. NR 484.04(23), shall be used to determine the concentration of vinyl chloride in each inprocess wastewater stream subject to the emission limit prescribed in s. NR 449.06(5). The mass of vinyl chloride in kilograms per 100 kilograms product in each inprocess wastewater stream shall be determined by using the following equation: See Image
(e) The vinyl chloride reactor opening loss for which an emission limit is prescribed in s. NR 449.06(1) (b) shall be determined. The number of reactors for which the determination shall be made shall be specified by the department for each individual plant at the time of the determination based on the plant's operation. For a vinyl chloride reactor that is also used as a stripper, the determination may be made immediately following the stripping operation. 1. Except as provided in subd. 2., the vinyl chloride reactor opening loss shall be determined using the following equation: See Image
Y is the number of batches since the vinyl chloride reactor was last opened to the atmosphere
Z is the average kg of polyvinyl chloride produced per batch in the batches since the vinyl chloride reactor was last opened to the atmosphere
a. If Method 106 is used to determine the concentration of vinyl chloride (Cb), the sample shall be withdrawn at a constant rate with a probe of sufficient length to reach the vessel bottom from the manhole. Samples shall be taken for 5 minutes within 6 inches of the vessel bottom, 5 minutes near the vessel center, and 5 minutes near the vessel top.b. If a portable hydrocarbon detector is used to determine the concentration of vinyl chloride (Cb), a probe of sufficient length to reach the vessel bottom from the service access hole shall be used to make the measurements. One measurement shall be made within 6 inches of the vessel bottom, one near the vessel center and one near the vessel top. Measurements shall be made at each location until the reading is stabilized. All hydrocarbons measured shall be assumed to be vinyl chloride.c. The production rate of polyvinyl chloride (Z) shall be determined by a method submitted to and approved by the department.2. A calculation based on the number of evacuations, the vacuum involved, and the volume of gas in the reactor is hereby approved by the department as an alternative method for determining reactor opening loss for past polymerization reactors in the manufacture of bulk resins.Wis.
