The bill focuses on enhancing the Toxics Use Reduction Act (TURA) in Massachusetts by introducing new legal language aimed at improving the reporting and tracking of toxic chemical use and byproducts. Key insertions include the establishment of a production ratio to adjust byproduct data, allowing for a more accurate assessment of reductions in toxic chemical use relative to production levels. The bill also emphasizes the inclusion of trade secret data in the reporting of total use, byproducts, and on-site releases, which aims to provide a comprehensive overview of chemical management while maintaining confidentiality for proprietary information. The report highlights significant reductions in toxic chemical use and byproducts from 2000 to 2023, with the 2000 Core Group achieving a 67% reduction in toxic chemical use and an 87% decrease in on-site releases. Additionally, the bill addresses the reporting requirements for facilities handling Persistent Bioaccumulative Toxic (PBT) chemicals and Higher Hazard Substances (HHS), noting a decrease in the number of facilities reporting lead and lead compounds. It introduces new legal language that specifies the exclusion of trade secret data from reported statistics and adds new PBTs and HHS, such as dioxin compounds and mercury compounds. The bill underscores the importance of ongoing monitoring of chemicals that can exacerbate health issues, such as asthma and cancer, and aims to enhance transparency and accountability in hazardous substance reporting, ultimately promoting public health and environmental safety in Massachusetts.
