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 449.09 - Emission tests

Current through June 24, 2024
(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				equivalent or alternative is withdrawn.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:

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:
