§ 703.7 EPA review of confidentiality claims under TSCA section 14(g).

(a) Representative subset and selection of submissions for review. (1) A representative subset consists of at least 25 percent of confidentiality claims asserted under TSCA, not including claims for specific chemical identity or for the categories of information listed in section 14(c)(2) of the Act. Excluded from the representative subset are:

(i) Inquiries with respect to potential submission to EPA of a notification under 40 CFR part 720, 721, 723, or 725 by a person who has not submitted the notification at the time of the inquiry, including inquiries under § 720.25(b) or § 721.11 of this subchapter;

(ii) Submissions or other communication not submitted to EPA via CDX; and

(iii) Amendments to previous TSCA submissions.

(2) To satisfy its confidentiality claim review obligations under section 14(g)(1)(C)(ii) of the Act, EPA will generally review all claims (except those exempt from substantiation under section 14(c)(2) of the Act) in every fourth TSCA submission submitted via CDX that is part of the representative subset, in chronological order of receipt by EPA. For each submission selected for review as part of the representative subset, EPA reviews and approves or denies every individual confidentiality claim in that submission (except claims that are exempt under sections 14(c)(2) and 14(g) of the Act), including claims made in attachments and amendments available to EPA at the time of the review.
