§ 63.9005 What are my general requirements for complying with this subpart?
(a) Before October 13, 2020, for each existing source, and for each new or reconstructed source for which construction or reconstruction commenced after April 17, 2003, but before February 5, 2019, you must be in compliance with the emission limitations and work practice standards in this subpart at all times, except during periods of startup, shutdown, and malfunction. After October 13, 2020, for each such source you must be in compliance with the emission limitations in this subpart at all times. For new and reconstructed sources for which construction or reconstruction commenced after February 4, 2019, you must be in compliance with the emissions limitations in this subpart at all times.
(b) Before October 13, 2020, for each existing source, and for each new or reconstructed source for which construction or reconstruction commenced after April 17, 2003, but before February 5, 2019, you must always operate and maintain your affected source, including air pollution control and monitoring equipment, according to the provisions in § 63.6(e)(1)(i). After October 13, 2020 for each such source, and after April 15, 2020 for new and reconstructed sources for which construction or reconstruction commenced after February 4, 2019, at all times you must operate and maintain any affected source, including associated air pollution control equipment and monitoring equipment, in a manner consistent with safety and good air pollution control practices for minimizing emissions. The general duty to minimize emissions does not require you to make any further efforts to reduce emissions if levels required by the applicable standard have been achieved. Determination of whether a source is operating in compliance with operation and maintenance requirements will be based on information available to the Administrator which may include, but is not limited to, monitoring results, review of operation and maintenance procedures, review of operation and maintenance records, and inspection of the source.
