The Pennsylvania Department of Environmental Protection’s (PADEP) Policy Office presented at the September 21, 2023, Water Resources Advisory Committee (WRAC) meeting on PADEP’s proposed regulation setting notification requirements for unauthorized discharges to waters of the commonwealth under 25 Pa. Code ch. 91. See PowerPoint Presentation, PADEP, “Notification Requirements for Unauthorized Discharges to Waters of the Commonwealth—Draft Proposed Rulemaking” (Sept. 21, 2023). Currently, the Pennsylvania Clean Streams Law requires PADEP to “determine when a discharge constitutes pollution” and to “establish standards whereby and wherefrom it can be ascertained and determined whether any such discharge does or does not constitute pollution.” 35 Pa. Stat. § 691.1. According to PADEP, the proposed amendments to chapter 91 are intended to enable the Department to meet its statutory obligation and set straightforward requirements for the public, the regulated community, and PADEP.
Under Pennsylvania’s Clean Water Program, the location and characteristics of authorized discharges—discharges permitted under a National Pollutant Discharge Elimination Permit, for example—are known prior to discharge. Permits are designed to ensure that these discharges do not cause or contribute to pollution, but unauthorized discharges—spills, for example—are unknown and unplanned. Many site-specific factors could affect whether the unauthorized discharge will result in pollution. Thus, the responsible party makes the first determination as to whether a discharge will cause or contribute to pollution, then PADEP investigates and assesses whether the discharge did or did not constitute pollution. PADEP intends for the chapter 91 updates to provide clearer reporting guidance and more consistent reporting for unauthorized discharges.
The draft proposed amendments to 25 Pa. Code § 91.33 detail factors to determine whether an unauthorized discharge will endanger downstream users or otherwise result in pollution or create a danger of pollution of waters of the commonwealth. These factors include the characteristics of the substances, the proximity to waters, the proximity to downstream users, the characteristics of the nearest waters, and the relevant infrastructure presence and qualities. At the WRAC meeting, PADEP gave examples of unauthorized discharges where notification would not be required, might be required, and would be required. For example, minor spills or leaks onto the ground where contaminated soil can be immediately removed, and there is no possibility of the substance reaching waters of the commonwealth, including groundwater or surface waters, directly or indirectly, would not be reportable. On the other hand, unanticipated bypasses of raw or inadequately treated sewage to waters of the commonwealth would be reportable.
The proposed rule also requires unauthorized discharges involving a quantity of a substance greater than the reportable quantity listed in 40 C.F.R. § 117.3 to be immediately reported to PADEP. PADEP rejected suggestions to use the water quality standards to determine “reportable quantities.” If the risk of pollution is unknown, the party in charge of the substance or the owner of the facility from which the substance is discharged must immediately notify PADEP. If requested by PADEP, a party claiming that they did not need to notify PADEP of a discharge must explain in a signed statement why the incident would not harm downstream users or result in pollution.
The proposed amendments are still in the pre-publication phase. In conjunction with the rulemaking, PADEP also intends to update its “Guidance on Reporting Requirements for Spills, Discharges, and other Incidents of a Substance Causing or Threatening Pollution to Waters of the Commonwealth Under Pennsylvania’s Clean Streams Law” to be consistent with the chapter 91 amendments.
