3) The remanufacturer or other person that stores or treats the hazardous secondary material at any facility in existence on the effective date of a statutory or regulatory amendment that renders the facility subject to this Subpart BB must comply with all requirements of this Subpart BB as soon as practicable but no later than 30 months after the amendment's effective date. When control equipment required by this Subpart BB cannot be installed and begin operation by the effective date of the statutory or regulatory amendment that renders the facility subject to this Subpart BB, the facility owner or operator must prepare an implementation schedule that includes the following information: specific calendar dates for award of contracts or issuance of purchase orders for the control equipment, initiation of on-site installation of the control equipment, completion of the control equipment installation, and performance of any testing to demonstrate that the installed equipment meets the applicable standards of this Subpart BB. The remanufacturer or other person that stores or treats the hazardous secondary material must keep a copy of the implementation schedule at the facility. BOARD NOTE: The federal effective date of this provision was July 15, 2015. The resulting compliance deadline for the Subpart BB standards was then January 18, 2018 for all facilities to which this Subpart BB applied on July 15, 2015. All new and modified facilities to which this Subpart BB applies are to immediately comply upon beginning operation after July 15, 2015. Where this Subpart BB becomes applicable to a facility subject to after July 15, 2015 as a result of statutory or regulatory amendment, compliance with the Subpart BB standards is required 30 months after the effective date of the statutory or regulatory amendment that subjected that facility to this provision.
