Compliance Requirements

This part of the standard specifies the conditions under which the facility is operated for the duration of the compliance test. Generally, a facility is required to operate under normal conditions. Operation under conditions greater than or much less than design levels is avoided unless it represents normal operation.

This part of the standard also specifies the test methods to be used and the averaging time for the test. The test method is usually either reference, equivalent, or alternative. The reference method is widely known and is usually published as part of the regulations. An equivalent method is one that has been demonstrated to have a known, consistent relationship with a reference method. An alternative method is needed when the characteristics of individual sources do not lend themselves to the use of a reference or equivalent method. An alternative method must be demonstrated to produce consistent and useable results. Averaging time for an emission standard is important if the source is variable in its emissions. A short averaging time is more variable and more likely to exceed a standard than a long averaging time.

MONITORING, REPORTING, AND RECORD KEEPING

Monitoring, reporting, and record-keeping requirements ensure that the facility is operating within normal limits and that control equipment is being properly operated and maintained. Data are generally kept at the facility for review at any time, but regular reporting of critical data to the regulatory agency may be required.
