The Compliance Assurance Monitoring, or CAM rule, evolved from the enforcement provisions of Title VI of the Clean Air Act Amendments of 1990 [sections 114 (a) (1) and 114 (a) (3) and the provisions of Title V that directs the USEPA to implement monitoring and compliance certification requirements through the operating permit program. The final rule (62 FR 54899) was promulgated by the USEPA on October 22, 1997.

CAM was developed by the USEPA as a tool or means for emissions units to verify compliance with emissions limits prescribed in Title V operating permits.

CAM is monitoring sufficient to provide a reasonable assurance of compliance with the applicable requirements such as emissions limits and to ensure that operators pay the same level of attention to pollution control measure as to production.


It is the intention of the USPEA that CAM will affect only those sources meeting specific applicability criteria, and in particular those emissions units with active pollution control devices. Once implemented, the goal of CAM is to provide reasonable assurance that a control device is operating satisfactorily, signifying that air emissions are within prescribed limits. In turn, the facility or source owner should have sufficient documentation to certify compliance for the source.

CAM is not only a rule but a philosophy. It is also a process intended to demonstrate that emissions controls are adequate to achieve compliance with applicable requirements, and thus, show that if the same controls are maintained and operated properly, one can reasonably assume that the emissions unit is in compliance.

For each CAM-affected source, a CAM plan is to be developed. Each CAM plan is prepared on a pollutant-by-pollutant basis for each emissions unit and requires the source to do the following:

1. Identify indicators for each affected control device that should be monitored to maintain process emissions within prescribed limits.
2. Establish acceptable ranges for these indicators.
3. Identify the monitoring approach that will be used to demonstrate that control devices perform as expected and, as a result, indicators are within the acceptable ranges.
4. Monitor any excursions from these indicator ranges.
5. Institute corrective action for these excursions.
6. Report excursions in the compliance certification reports.
