On April 5, 2025, the Environmental Quality Board (EQB) published a public notice proposing to amend 25 Pa. Code § 91.33 (relating to incidents causing or threatening pollution). See 55 Pa. Bull. 2589 (Apr. 5, 2025). This proposed rule intends to clarify which unauthorized discharges require immediate notification to the Pennsylvania Department of Environmental Protection (PADEP) but does not change which unauthorized discharge incidents require immediate PADEP notification.
Section 91.33 currently requires the person responsible for an unauthorized discharge to immediately notify PADEP if a discharge results in pollution, creates a danger of pollution of the waters of the Commonwealth, or would damage property. The proposed rule would require a person responsible for unauthorized discharges to either report the discharge to PADEP immediately, or create and retain a written analysis of certain factors determining that an unauthorized discharge does not cause or threaten pollution. A signed statement attesting the document’s accuracy must accompany the documentation if it is provided to PADEP at PADEP’s request. The proposed rule would require analysis of the following factors:
- the properties of the substance or substances discharged;
- the location or locations involved;
- the weather conditions before, during, and after the incident;
- the presence and implementation of adequate response plans, procedures, or protocols; and
- the duration of the accident or other activity or incident.
If any one of the above factors, or a combination of the factors, can adequately establish that there is no risk of the substance reaching waters of the Commonwealth, no further analysis of the other factors is required to determine whether immediate notification to PADEP is required. …
