(a) Periodic monitoring applies to an emission unit at a site that is subject to this chapter provided the emission unit is subject to an emission limitation or standard in an applicable requirement except as noted in subsection (b) of this section.
(b) Periodic monitoring shall not apply to emission limitations or standards for which the executive director has determined that the applicable requirement has periodic monitoring (which may consist of recordkeeping) sufficient to yield reliable data from the relevant time period that are representative of the emission unit's compliance with the applicable requirement, and testing, monitoring, reporting, or recordkeeping sufficient to assure compliance with the applicable requirement. These emission limitation or standards include, but are not limited to, the following:
  (1) emission limitations or standards proposed by the EPA after November 15, 1990 under FCAA, §111 (Standards of Performance for New Stationary Sources) or §112 (Hazardous Air Pollutants);
  (2) emission limitations or standards under FCAA, Title IV (the Acid Rain Program);
  (3) emission limitations or standards for which an applicable requirement specifies a continuous compliance determination method, unless the applicable compliance method includes an assumed control device emission reduction factor that could be affected by the actual operation and maintenance of the control device (such as a surface coating line controlled by an incinerator for which continuous compliance is determined by calculating emissions on the basis of coating records and an assumed control device efficiency factor based on an initial performance test); and
  (4) other emission limitations or standards specified as exempt by the EPA.
