Petitioning EPA to add or delete a TRI chemical

Any person may petition EPA to add or delete a chemical from the TRI list of covered chemicals (40 CFR §372.20(d)). What should a person include in a petition to add or delete a listed TRI chemical?

A petitioner should provide EPA with enough information concerning his or her request and as much credible scientific support documentation as can reasonably be developed to assist EPA in reviewing the petition. The following elements illustrate the type of information that would assist EPA in reviewing petitions: chemical identification, specific criteria elements, rationale, published literature citations, and unpublished information.

The summary of the petition should include the following:

  • Name, address and telephone number of the petitioner, and a description of any organization that the person represents if applicable
  • Actions requested (i.e., to add or delete chemicals), and in the case of additions, which of the criteria in EPCRA §313(d)(2) the chemicals meet
  • If more than one chemical is involved, a tabular summary of the specific chemicals should be provided with associated chemical abstract service (CAS) registry numbers

The body of the petition should be chemical-specific and should be structured so that each chemical and its CAS number are listed at the heading of the paragraph or page that describes it. The associated information elements could be presented under the following subheadings: the action requested (i.e., to add or to delete); the specific criteria elements that the chemical meets; the justification or rationale, including a statement explaining why the chemical meets or does not meet the stated criteria elements. A listing or attachment of the supporting documents should also be included with the petition.

The petition should be sent to the following address:

Director
Office of Information Analysis and Access (Mail Code 2841T)
Office of Environmental Information
Environmental Protection Agency
1200 Pennsylvania Avenue, N.W.
Washington, D.C. 20460
