Guidance to Assist Interested Persons in Developing and Submitting Draft Risk Evaluations Under TSCA

EPA has developed a guidance document to assist interested persons (also called external parties) in developing and submitting draft risk evaluations to EPA. The Guidance describes the science standards, data quality considerations, and the steps of the risk evaluation process that external parties should follow when developing draft TSCA risk evaluations. EPA’s expectation is that external party draft risk evaluations will be of the same high quality as those developed by EPA.

EPA is interested in receiving public comments at any time to strengthen the guidance document. EPA will, at the least, review the guidance every 5 years and determine whether updating is necessary, per TSCA section 26(l)(2).  Beyond that, EPA strives to provide timely updates to the guidance document to ensure the effective use of the guidance by external parties. After public comments are reviewed, EPA would update the guidance as appropriate.
