The Toxics Use Reduction Act (TURA) became law in 1989 and was amended in 2006. It requires Massachusetts companies that use large quantities of specific toxic chemicals to evaluate their operations, plan for pollution prevention, and report on the results each year. TURA does not restrict the use of any substance.
Each company subject to TURA needs to file annual reports, prepare plans and updates, and pay fees for the listed chemicals it manufactures, processes or otherwise uses above the specified thresholds.
The list of chemicals provided in Pharos is larger than the list downloadable from the MassDEP Toxics Use Reduction Program guide (link provided) because the Pharos list includes additional individual chemicals in the listed groups, eg Antimony Compounds.
