# §63.9301. What are my options for meeting the emission limits?


You may use either a continuous parameter monitoring system (CPMS) or a continuous emission monitoring system (CEMS) to demonstrate compliance with the emission limitations. Continuous monitoring systems must meet the requirements in [§ 63.9306 (CPMS)](/cfr/40/63.9306.md?p=CPMS) and [§ 63.9307 (CEMS)](/cfr/40/63.9307.md?p=CEMS).
