This bill directs owners and operators of gas distribution pipeline facilities to conduct an assessment of their systems for the presence of Aldyl-A polyethylene within three years of enactment. This assessment does not require excavation activities, and operators must report the estimated total mileage of identified Aldyl-A piping to the Secretary. Furthermore, the legislation amends federal pipeline safety statutes to enhance oversight of older, potentially hazardous materials. It modifies provisions related to State Pipeline Safety Program Certifications to include pipelines constructed of "historic plastics with known safety issues" alongside cast iron and bare steel pipelines. Additionally, it expands the scope of risk evaluations within Distribution Integrity Management Programs to consider the presence of pipes made from historic plastics, unprotected steel, and wrought iron, in addition to cast iron, thereby strengthening safety protocols for aging infrastructure.
