  "definition": "1. Monitoring and record keeping are key elements for ensuring that permits are enforceable as a practical matter. Some applicable requirements do not contain adequate provisions for determining whether a source is in compliance with the emissions standard. For example, if a source meets an emissions limit by operating its incinerator at a specified temperature but is not required by the applicable requirement to monitor and record the temperature, it is not possible to determine whether the source has complied with the limit. Another example is that some applicable requirements will specify that the source must conduct a test when it initially begins operation, but do not require any ongoing monitoring.\n\n2. In writing the part 70 regulations, EPA recognized that some applicable requirements lack adequate monitoring. Under part 70, if the monitoring in the applicable requirement is not adequate, the permitting authority must add monitoring beyond what is required by the applicable requirement to the Title V permit. Types of monitoring include record keeping, periodic source testing, or use of continuous emissions monitoring systems (CEMS).",
