The Compliance Assurance Monitoring, or CAM, rule is designed to satisfy the requirements for monitoring and compliance certification in the Part 70 operating permits program and Title VII of the 1990 Clean Air Act Amendments. The CAM rule includes a new Part 64 and associated revisions to the Part 70 (permits program) monitoring and compliance certification requirements. The rule would establish criteria that define the monitoring, reporting, and record keeping that should be conducted by a source to provide a reasonable assurance of compliance with emission limitations and standards. These criteria address defining the applicable monitoring approach, obligation to complete corrective actions as indicated by the monitoring results, and how such data are used in the annual compliance certification.

The applicable monitoring approach for any operation or facility depends on the control technology used to meet the applicable emission limit and includes monitoring of operational and control device parameters indicative of pollution control performance and record keeping of work practice and inspection procedures necessary to assure compliance operation. The final CAM Rule was published in the Federal Register on October 22, 1997.
