Bill > HB222

This bill prohibits the sale, offer for sale, transfer, or distribution of non-arc-resistant jacketed corrugated stainless steel tubing (CSST) in Maryland, which is a type of flexible metal gas line used in residential and commercial buildings. The bill establishes a civil penalty of up to $1,000 for violations and restricts the use of non-arc-resistant CSST in new construction, renovations affecting more than 50% of a property's square footage, and new gas line additions. Additionally, the bill requires the Maryland Department of Labor and the Office of the State Fire Marshal to conduct a comprehensive study on fuel gas piping systems by September 1, 2026. The study will examine fire hazard risks associated with different types of gas piping, including the potential for fires caused by lightning strikes, analyze existing standards and requirements, identify best practices for legislative and building code standards, and assess the prevalence and risks of non-arc-resistant CSST in buildings. The researchers must consult with various stakeholders, including the State Fire Prevention Commission, local government entities, and manufacturers of fuel gas piping systems. The study will culminate in an interim report by December 1, 2025, and a final report with recommendations by September 1, 2026, which will be submitted to the Governor and specific legislative committees. The bill is set to take effect on June 1, 2025.
