Yes, subpart B of this part establishes general requirements for developing and processing section 111(d) plans. This subpart applies instead of the requirements in subpart B of this part for the following:
(a) State plans developed to implement this subpart must be as protective as the emission guidelines contained in this subpart. State plans must require all existing incineration units to comply with the emissions and operating limits at all times by July 1, 2030, or 3 years after the effective date of state plan approval, whichever is sooner. This applies instead of the option for case-by-case less stringent emission standards and longer compliance schedules in § 60.24(f).
(b) State plans developed to implement this subpart are required to include only one increment of progress for the affected incineration units. This increment is the final compliance date in § 60.21(h)(5). This applies instead of the requirement of § 60.24(e)(1).
