(a) This subpart can be implemented and enforced by the U.S. EPA, or a delegated authority such as a State, local, or tribal agency. If the U.S. EPA Administrator has delegated authority to a State, local, or tribal agency pursuant to 40 CFR part 63, subpart E, then that Agency has the authority to implement and enforce this subpart. You should contact your U.S. EPA Regional Office to find out if this subpart is delegated to a State, local, or tribal agency.
(b) In delegating implementation and enforcement authority of this subpart to a State, local, or tribal agency under 40 CFR part 63, subpart E, the authorities contained in paragraphs (b)(1) through (4) of this section are retained by the Administrator of the U.S. EPA and are not transferred to the State, local, or tribal agency.
(1) Approval of an alternative non-opacity emissions standard under Sec. 63.6(g).
(2) Approval of a major change to test methods under Sec. 63.7(e)(2)(ii) and (f). A ``major change to test method'' is defined in Sec. 63.90.
(3) Approval of a major change to monitoring under Sec. 63.8(f). A ``major change to monitoring'' is defined in Sec. 63.90.
(4) Approval of a major change to recordkeeping/reporting under Sec. 63.10(f). A ``major change to recordkeeping/reporting'' is defined in Sec. 63.90.
As required in Sec. 63.11409, you must install and operate capture systems and comply with the applicable emissions limit for each emissions source shown in the following table. [72 FR 38905, July 16, 2007, as amended at 73 FR 15928, Mar. 26, 2008]
