(a) If you use a solvent recovery system and/or solvent substitution, you must demonstrate continuous compliance with the emission limitations for solvent mixers in Sec. 63.9500(a) and (b) according to the provisions in paragraphs (a)(1) through (3) of this section.
(1) Except for during malfunctions of your weight measurement device and associated repairs, you must collect and record the information required in Sec. 63.9520(a)(1) through (8) at all times that the affected source is operating and record all information needed to document conformance with these requirements.
(2) For new, reconstructed, or existing large solvent mixers, maintain the 7-day block average percent of HAP solvent discharged to the atmosphere at or below 30 percent of that which would otherwise be emitted in the absence of solvent recovery and/or solvent substitution.
(3) For new, reconstructed, or existing small solvent mixers, maintain the 7-day block average percent of HAP solvent discharged to the atmosphere at or below 15 percent of that which would otherwise be emitted in the absence of solvent recovery and/or solvent substitution.
(b) If you use a control technique other than a solvent recovery system and/or solvent substitution, you must demonstrate continuous compliance with the emission limitations for solvent mixers in Sec. 63.9500(a) and (b) according to the provisions in Sec. 63.9570.
(c) You must report each instance in which you did not meet the emission limitations for solvent mixers in Sec. 63.9500(a) and (b). This includes periods of startup, shutdown, or malfunction. These instances are deviations from the emission limitations in this subpart. These deviations must be reported according to the requirements in Sec. 63.9540.
(d) [Reserved]
(e) Consistent with Secs. 63.6(e) and 63.7(e)(1), deviations that occur during a period of startup, shutdown, or malfunction are not violations if you demonstrate to the Administrator's satisfaction that you were operating in accordance with Sec. 63.6(e)(1). The Administrator will determine whether deviations that occur during a period of startup, shutdown, or malfunction are violations, according to the provisions in Sec. 63.6(e).
