The notification and reporting requirements in §63.122 do not apply to the owner or operator of the offsite cleaning or reloading facility.
(iii) If complying with paragraph (g)(6)(ii) of this section, keep the records specified in §63.123(i)(3).
(iv) After the compliance dates specified in §63.100(k) at an offsite reloading or cleaning facility subject to paragraph (g) of this section, compliance with the monitoring, recordkeeping, and reporting provisions of any other subpart of this part 63 constitutes compliance with the monitoring, recordkeeping, and reporting provisions of paragraph (g)(7)(ii) or (iii) of this section.
