(g) Volatile matter retained in the coated web or otherwise not emitted to the atmosphere. You may choose to take into account the mass of volatile matter retained in the coated web after curing or drying or otherwise not emitted to the atmosphere when determining compliance with the emission standards in
s. NR 466.23 (1). If you choose this option, you shall develop a testing protocol to determine the mass of volatile matter retained in the coated web or otherwise not emitted to the atmosphere and submit this protocol to the department for approval. You shall submit this protocol with your site-specific test plan under
s. NR 460.06 (5). If you intend to take into account the mass of volatile matter retained in the coated web after curing or drying or otherwise not emitted to the atmosphere and demonstrate compliance according to
s. NR 466.25 (3) (c),
(d),
(e) or
(4), the test protocol you submit shall determine the mass of organic HAP retained in the coated web or otherwise not emitted to the atmosphere. Otherwise, compliance shall be shown using the volatile organic matter content as a surrogate for the HAP content of the coatings.
NR 466.24(3)(h)
(h) Control devices in series. If you use multiple control devices in series to comply with the emission standards in
s. NR 466.23 (1), the performance test shall include, at a minimum, the inlet to the first control device in the series, the outlet of the last control device in the series, and all intermediate streams, such as gaseous exhaust to the atmosphere or a liquid stream from a recovery device, that are not subsequently treated by any of the control devices in the series.
