Pennsylvania enacts new hydraulic fracturing chemical disclosure regulations effective July 2025

On April 28, 2025, the Pennsylvania Legislature introduced Senate Bill 660, aimed at enhancing transparency in hydraulic fracturing operations. The bill seeks to amend existing regulations regarding the disclosure of chemical products used in the hydraulic fracturing process, a method often criticized for its environmental impact and potential health risks.

The primary purpose of Senate Bill 660 is to ensure that manufacturers provide detailed information about chemical products used in hydraulic fracturing to service providers, vendors, or operators at the time of sale. This includes the manufacturer's name, trade name, amount or weight of the chemical, and, if available, a safety data sheet. Operators are required to complete a chemical disclosure registry form within 60 days after the conclusion of hydraulic fracturing and post this information on a public registry.

Key provisions of the bill include a mandatory disclosure timeline, which stipulates that the information must be furnished by July 31, 2025. This requirement aims to improve public access to information about the chemicals used in hydraulic fracturing, addressing concerns from environmental groups and local communities about the potential risks associated with these substances.

Debate surrounding the bill has highlighted concerns from both proponents and opponents. Supporters argue that increased transparency will empower communities to make informed decisions about local environmental health, while critics contend that the bill may not go far enough in regulating the industry and ensuring public safety. Amendments to the bill have been proposed to strengthen disclosure requirements further, but these have faced resistance from industry stakeholders who argue that excessive regulation could hinder economic growth.

The implications of Senate Bill 660 are significant, as it reflects a growing trend toward stricter environmental regulations in the energy sector. Experts suggest that if passed, the bill could lead to increased scrutiny of hydraulic fracturing practices and potentially influence similar legislative efforts in other states. The outcome of this bill may also set a precedent for how chemical disclosures are handled in the future, balancing industry interests with public health and environmental protection.

As the legislative process continues, stakeholders are closely monitoring developments, with discussions expected to intensify as the July deadline approaches. The bill's progress will be a critical indicator of Pennsylvania's commitment to environmental transparency and public safety in the face of ongoing debates about the future of fossil fuel extraction.
