§ 63.4542 How do I demonstrate continuous compliance with the emission limitations?

(a) For each compliance period to demonstrate continuous compliance, you must use no coating for which the organic HAP content (determined using Equation 1 of § 63.4541) exceeds the applicable emission limit in § 63.4490, and use no thinner and/or other additive, or cleaning material that contains organic HAP, determined according to § 63.4541(a). A compliance period consists of 12 months. Each month, after the end of the initial compliance period described in § 63.4540, is the end of a compliance period consisting of that month and the preceding 11 months. If you are complying with a facility-specific emission limit under § 63.4490(c), you must also perform the calculation using Equation 1 in § 63.4490(c)(2) on a monthly basis using the data from the previous 12 months of operation.
