25 Pa. Code § 121.8
Compliance with any provision of this title may not relieve a person of the responsibility to comply with other provisions of this title, except when the relief has been clearly provided for in this title. Unless explicit reference is made to another section, each section of this title is construed and enforced according to its own terms. Thus, for example and without limitation on the general application of this section, compliance with both §§ 123.1 and 123.41 (relating to prohibition of certain fugitive emissions; and limitations) shall be attained whether or not emissions comply with §§ 123.11-123.13 (relating to particulate matter emissions). Compliance with each section of this title will be independently determined.
