||Under the amended TURA statute, the Science Advisory Board (SAB) is responsible for recommending up to 10 chemicals per year as higher hazard substances and up to 10 as lower hazard substances. The SAB makes their recommendations to TURI based upon science, and TURI then conducts a policy review. TURI then makes recommendations to the Administrative Council, which is responsible for the final designations of higher and lower hazard substances.
Potential higher hazard chemicals include:
Trichloroethylene (TCE), Perchloroethylene (PCE, or “perc”), Cyanide Compounds, Hydrogen Cyanide, Formaldehyde, Arsenic, Benzene, Chlorine, Ethylene Oxide, Nickel Compounds, and Cadmium Compounds.
Potential lower hazard chemicals include:
N-butyl alcohol, Sec-butyl alcohol, Ethylene glycol, Methanol, Silver in alloy form, Zinc in alloy form, Acetone, Acetic acid (>12 percent concentration), Isobutyl alcohol, Methyl Ethyl Ketone, and Ethyl Acetate.
The SAB and TURI are also in the process of evaluating TURA chemicals originating from the CERCLA chemical list to make a recommendation to the Administrative Council as to which chemicals should be retained. The next Administrative Council public meeting is October 31, 2007, 1:30pm – 3:30pm, 100 Cambridge Street, Boston, MA.
