EPA Plans Risk Evaluation Of Grandfathered Chemicals

By Chemical Processing Staff

The Environmental Protection Agency (EPA) is moving swiftly to propose how it will prioritize and evaluate chemicals, given that the final processes must be in place within the first year of the new law’s enactment, or before June 22, 2017. When the Toxic Substances Control Act (TSCA) was enacted in 1976, it grandfathered in thousands of unevaluated chemicals that were in commerce at the time. The old law failed to provide EPA with the tools to evaluate chemicals and to require companies to generate and provide data on chemicals they produced.

“After 40 years we can finally address chemicals currently in the marketplace,” says Jim Jones, EPA's assistant administrator for the Office of Chemical Safety and Pollution Prevention.

EPA is proposing three rules to help administer the new process;

Inventory rule. There are currently over 85,000 chemicals on EPA’s Inventory, many of these are no longer actively produced. The rule will require manufacturers, including importers, to notify EPA and the public on the number of chemicals still being produced.

Prioritization rule. This will establish how EPA will prioritize chemicals for evaluation.  EPA will use a risk-based screening process and criteria to identify whether a particular chemical is either high or low priority.  A chemical designated as high-priority must undergo evaluation. Chemicals designated as low-priority are not required to undergo evaluation.

Risk Evaluation rule. This will establish how EPA will evaluate the risk of existing chemicals.  The agency will identify steps for the risk evaluation process, including publishing the scope of the assessment. Chemical hazards and exposures will be assessed along with characterizing and determining risks.  This rule also outlines how the agency intends to seek public comment on chemical evaluations.

These three rules incorporate comments received from a series of public meetings held in August 2016. If EPA identifies unreasonable risk in the evaluation, it is required to eliminate that risk through regulations.  Under TSCA the agency must have at least 20 ongoing risk evaluations by the end of 2019.
