Wisconsin Administrative Code › Department of Natural Resources › NR 400-499 - Environmental Protection - Air Pollution Control › Chapter NR 449 - Control of vinyl chloride emissions › Section NR 449.12 - Semiannual report

Current through June 24, 2024
(1) The owner or operator of any source
				subject to this chapter shall submit to the department on September 15 and
				March 15 of each year a report in writing containing the information required
				by this section.
(2) The first
				semiannual report shall be submitted within 180 days of the initial startup
				date of a source on which construction or modification commenced after February
				1, 1984.
(3) Unless otherwise
				specified, the owner or operator shall use the Methods of 40 CFR part 61,
				Appendix B, incorporated by reference in s.
				NR
				484.04(23), to conduct emission tests
				as required by pars. (b) and (c), unless an equivalent 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				equivalent or alternative is withdrawn.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)
				The owner or operator shall include in the report a record of any emissions
				which averaged over any hour period (commencing on the hour) are in excess of
				the emission limits prescribed in s.
				NR
				449.04(1) or (2),
				449.05(1) or
				449.06(1) (a), (2), (3) or
				(4), or for 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. The emissions shall be measured in
				accordance with s.
				NR
				449.10.
(b) In polyvinyl chloride plants for which a
				stripping operation is used to attain the emission level prescribed in s.
				NR
				449.06(5), the owner or operator
				shall include in the report a record of the vinyl chloride content in the
				polyvinyl chloride resin. Method 107 of 40 CFR part 61, Appendix B,
				incorporated by reference in s.
				NR
				484.04(23), shall be used to
				determine vinyl chloride content in accordance with this paragraph.
1. If batch stripping is used, one
				representative sample of polyvinyl chloride resin shall be taken from each
				batch of each grade of resin immediately following the completion of the
				stripping operation and identified by resin type and grade and the date and
				time the batch is completed. The corresponding quantity of material processed
				in each stripper batch shall be recorded and identified by resin type and grade
				and the date and time the batch is completed.
2. If continuous stripping is used, one
				representative sample of polyvinyl chloride resin shall be taken for each grade
				of resin processed, whichever is more frequent. The sample shall be taken as
				the resin flows out of the stripper and identified by resin type and grade and
				the date and time the sample was taken. The corresponding quantity of material
				processed by each stripper over the time period represented by the sample
				during the 8-hour period shall be recorded and identified by resin type and
				grade and the date and time it represents.
3. The quantity of material processed by the
				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 subds. 1. and 2.
5. The report to the department by the owner
				or operator shall include the vinyl chloride content found in each sample
				required by subds. 1. and 2., averaged separately for each type of resin, over
				each calendar day and weighted according to the quantity of each grade of resin
				processed by the stripper or strippers that calendar day, according to the
				following equation:
See
				  Image
Gi is the grade of resin (e.g.,
				  G1 , G2 and
				  G3 )
n is the total number of grades of resin produced during the
				  24-hour period
6. Records
				of all data needed to furnish the information required by subd. 5. shall be
				retained at the source and made available for inspection by a department
				representative for a minimum of 3 years. The records shall contain:
a. The vinyl chloride content found in all
				the samples required in subds. 1. and 2., identified by the resin type and
				grade and the time and date of the sample, and
b. The corresponding quantity of polyvinyl
				chloride resin processed by the stripper or strippers identified by the resin
				type and grade and the time and date it represents.
(c) The owner or operator shall
				include in the report a record of the emissions from each reactor opening for
				which an emission limit is prescribed in s.
				NR
				449.06(1) (b). Emissions shall be
				determined in accordance with s.
				NR
				449.09(6) (e), except that emissions
				for each reactor are to be determined. For a reactor that is also used as a
				stripper, the determination may be made immediately following the stripping
				operation.
