The agenda for the August 9, 2022, Pennsylvania Environmental Quality Board (EQB) meeting included a vote on the final rulemaking for water quality standards for manganese in 25 Pa. Code chs. 93 and 96. This rulemaking was prompted by the addition of subsection (j) to section 1920-A of the Administrative Code of 1929, 71 Pa. Stat. § 510-20, by Act 40 of 2017. Act 40 directed the EQB to promulgate regulations under Pennsylvania’s Clean Streams Law, 35 Pa. Stat. §§ 691.1–.1001, and related statutes to require that the water quality criteria for manganese established under 25 Pa. Code ch. 93 be met.
The EQB approved the proposed manganese rule in December 2019 and the Pennsylvania Department of Environmental Protection (PADEP) held three public hearings on the rulemaking in 2020. See Vol. XXXVII, No. 4 (2020); Vol. XXXVII, No. 1 (2020) of this Newsletter. Since the proposed rulemaking, PADEP has met with the Mining and Reclamation Advisory Board, the Aggregate Advisory Board, the Public Water Systems Technical Assistance Center Board, and the Water Resources Advisory Committee to discuss the proposed rule.
The proposed manganese rule adds to table 5 in 25 Pa. Code § 93.8c a numeric water quality criterion for manganese of 0.3 mg/L intended to “protect human health from the neurotoxicological effects of manganese.” Executive Summary at 1. Section 93.8c establishes human health and aquatic life criteria for toxic substances, meaning PADEP is now regulating manganese as a toxic substance. …
