# §63.1181. How do I comply with the particulate matter standards for existing, new, and reconstructed cupolas?


To comply with the PM standards, you must meet all of the following:

- (a) Install, adjust, maintain, and continuously operate a bag leak detection system for each fabric filter.
- (b) Do a performance test as specified in [§ 63.1188](/cfr/40/63.1188.md) of this subpart and show compliance with the PM emission limits while the bag leak detection system is installed, operational, and properly adjusted.
- (c) Begin corrective actions specified in your operations, maintenance, and monitoring plan required by [§ 63.1187](/cfr/40/63.1187.md) of this subpart within one hour after the alarm on a bag leak detection system sounds. Complete the corrective actions in a timely manner.
- (d) Develop and implement a written QIP consistent with compliance assurance monitoring requirements of [40 CFR 64.8(b) through (d)](/cfr/40/64.8.md?p=b..d) when the alarm on a bag leak detection system sounds for more than five percent of the total operating time in a six-month reporting period.
