Traditionally, the stationary source air compliance program has required facilities subject to air emissions standards to demonstrate their ability to comply with the emissions standards during an initial source performance tests. Demonstrating compliance at start-up, however, does not assure that a source will remain in compliance. To assure compliance after start-up, EPA`s responsibility to catch those in violation of standards. Under the 1990 Clean Air Act Amendments (CAAA 1990), Congress, shifted the burden of assuring compliance from the administrator to the owner or operator of the source. This shift will be implemented through the Enhanced Monitoring (EM) rule. Congress put specific language in the Act to allow flexibility for innovative alternatives to continuous emissions monitoring systems (CEMs). Section 504(b) states that {open_quotes}continuous emissions monitoring need not be required if alternative methods are available that provide sufficient reliable and timely information for determining compliance.{close_quotes} Section 114 (a)(3) permits the Administrator to accept as Enhanced Monitoring, records on control equipment parameters, production variables or other indirect data as an alternative to direct emission measurements. This alternative, Parametric Monitoring, is acceptable if the facility can demonstrate a correlation between the applicable emission standard and the parameters being monitored. Common approaches to the use of parametric monitoring are illustrated here through a brief overview of three enhanced monitoring protocols. The first example uses boiler output to predict quantitative nitrogen oxides (NO{sub x}) emission rates from a gas-fired electric utility boiler. The second example uses parametric data collected in the operation of a venturi scrubber to determine compliance or noncompliance with a particulate emissions limitation. The third example illustrates an alternative use of parametric data collected from a venturi scrubber.
