The LA portion of the TMDL will be allotted to nonpoint source pollutant loadings and natural quality.

(h) The Department will revise WLAs and LAs because of new or increased pollutant loadings. WLAs shall be revised at or before the expiration date of the current point source discharge permit term.

(i) The Department may require NPDES dischargers and other persons subject to regulation under The Clean Streams Law (35 P. S. § § 691.1—691.1001) to conduct appropriate monitoring of pollutant sources and waters and report the results and data, to obtain data needed to develop TMDLs and effluent limitations and to determine their effectiveness.
