    (A) Permitted facility--For a facility with a permit under this chapter, the allowable emissions shall be any emission limit established in the permit on a maximum allowable emissions rate table and any emission limit contained in representations in the permit application which was relied upon in issuing the permit, plus any allowable emissions authorized under Chapter 106 of this title (relating to Permits by Rule).
    (B) Facility permitted by rule--For a facility operating under Chapter 106 of this title, the allowable emissions shall be the least of the emissions rate allowed in Chapter 106, Subchapter A of this title (relating to General Requirements), the emissions rate specified in the applicable permit by rule, or the federally enforceable emission rate established in accordance with §106.6 of this title (relating to Registration of Emissions).
    (C) Standard permit facility--For a facility authorized by standard permit, other than the Air Quality Standard Permit for Pollution Control Projects, the allowable emissions shall be the maximum emissions rate represented in the registration to use the standard permit.
    (D) Special exemption facility--For a facility operating under a special exemption, the allowable emissions shall be the emissions rate represented in the original special exemption request.
  (3) Revision--A change made in the conditions or emission rates of a permit issued under §116.111 of this title (relating to General Application), or to the representations in the registration for a standard permit issued under Subchapter F of the chapter (relating to Standard Permits) to codify physical changes or new emission rates as authorized by §116.116(e) of this title (relating to Changes at Facilities).
