Applicability and Principle 1.1 Applicability. This specification contains requirements for the design. performance, and installation of instruments for opacity continuous emission monitoring systerms (CEMS's) and data computation procedures for evaluating the acceptability of a CEMS. Certain design requirements and test procedures established in this specification may not apply to all instrument designs. In such instances, equivalent design requirements and test procedures may be used with prior approval of the Administrator. Performance Specification 1 (PS 1) applies to opacity monitors installed after March 30, 1983. Opacity monitors installed before March 30, 1983, are required to comply with the provisions and requirements of PS 1 except for the following: (a) Section 4. "Installation Specifications." (b) Sections 5.1.4, 5.1.6, 5.1.7, and 5.1.8 of Section 5. "Design and Performance Specifications." (c) Section 6.4 of Section 6 "Design Specifications Verification Procedure." An opacity monitor installed before March 30, 1983, need not be tested to demonstrate compliance with PS 1 unless required by regulatory action other than the promulgation of PS 1. If an existing monitor is replaced with a new monitor, PS I shall apply except that the new monitor may be located at the old measurement location regardless of whether the location meets the requirements of
