§ 705.15 - What information to report.

For the one-time submission, persons identified in § 705.10 must report to EPA, for each site of each of the chemical substances identified in § 705.5, the following information to the extent known to or reasonably ascertainable by them, except as allowed under § 705.18. In the event that actual data is not known to or reasonably ascertainable by the submitter, then reasonable estimates may be submitted:

(a) Company and plant site information. The following currently correct company and plant site information must be reported for each site at which a reportable chemical substance is manufactured (see 40 CFR 711.3 for the “site” for importers):

(1) The highest-level U.S. parent company name, address, and Dun and Bradstreet D-U-N-S® (D&B) number, if one exists.

(2) The name of a person who will serve as Authorized Official for the submitter company, and who will be able to sign the certification statement as described in § 705.30(d), the Authorized Official's full mailing address, telephone number, and email address.

(3) The name of a person who will serve as technical contact for the submitter company, and who will be able to answer questions about the information submitted by the company to EPA, the contact person's full mailing address, telephone number, and email address.

(4) The name, full street address, and six-digit North American Industry Classification System (NAICS) code(s) of the site. A submitter under this part must include the appropriate D&B number for each plant site reported, and the county or parish (or other jurisdictional indicator) in which the plant site is located. A submitter under this part must obtain a D&B number for the site reported if none exists. A submitter under this part must also provide other site identification numbers, including the Facility Registry Service (FRS) identification number, if they exist.

(b) Chemical-specific information. The following chemical-specific information must be reported for each chemical substance that is a PFAS manufactured for each year since January 1, 2011, except as allowed under § 705.18. This includes each chemical substance that is a PFAS and incorporated into mixtures:

(1) The common or trade name, the chemical identity, and, except for chemical substances that are Class 1 substances on the TSCA Inventory, the representative molecular structure of each PFAS for which such a report is required.

(i) The specific, currently correct Chemical Abstracts (CA) Index name as used to list the chemical substance on the TSCA Inventory and the correct corresponding Chemical Abstracts Service Registry Number (CASRN) for each reportable PFAS at each site. Submitters who wish to report chemical substances listed on the confidential portion of the TSCA Inventory will need to report the chemical substance using a TSCA Accession Number. If a submitter has a low-volume exemption (LVE) case number for the chemical substance, that number may also be used if a CASRN is not known to or reasonably ascertainable by the submitter.

(ii) In addition to reporting the number itself, submitters must specify the type of number they are reporting by selecting from among the codes in table 1 to this paragraph (b)(1)(ii).

Table 1 to Paragraph (b)(1)(ii)—Codes To Specify Type of Chemical Identifying Number

Code	Number type
A	TSCA Accession Number.
C	Chemical Abstracts Service Registry Number (CASRN).
L	Low-volume exemption (LVE) case number.

(iii) If the CASRN or specific identifier (i.e., Accession Number or LVE number) of the PFAS is not known to or reasonably ascertainable (NKRA) to the submitter (e.g., if the chemical identity is claimed as confidential business information by the submitter's supplier, or if the submitter knows they have a PFAS but are unable to ascertain its specific identifier and/or specific chemical identity), the submitter may provide a generic name or description of the PFAS and also initiate a joint submission if the secondary submitter is known. The submitter may only initiate a joint submission if the CASRN or the specific identifier (i.e., Accession Number or LVE number) is not known or reasonably ascertainable, and a secondary submitter (who would provide such information) is known. The manufacturer (including importer) must use the reporting tool described under § 705.35 to ask the supplier or other entity to provide the chemical identity directly to EPA in a joint submission. Such request must include instructions for submitting chemical identity information electronically, using e-CDRweb and CDX (see 40 CFR 711.35), and for clearly referencing the manufacturer's (including importer) submission. Contact information for the supplier or other entity, a trade name or other designation for the chemical substance, and a copy of the request to the supplier or other entity must be included with the manufacturer's (including importer) submission. If, after conducting due diligence and reviewing known or reasonably ascertainable information, a secondary submitter to complete the joint submission is not known, the reporter may indicate that the secondary submitter is NKRA. However, the PFAS manufacturer would be required to provide as much identifying detail as they have regarding the PFAS identity, and would be able to report to EPA without initiating a joint submission even if they do not know the underlying identity of the chemical substance.

(2) The physical form(s) of the PFAS as it is sent off-site from each site. If the PFAS is site-limited, you must report the physical form(s) of the PFAS at the time it is reacted on-site to produce a different chemical substance. For each PFAS at each site, the submitter must report as many physical forms as applicable from among the physical forms listed in this unit:

(i) Dry powder.

(ii) Pellets or large crystals.

(iii) Water- or solvent-wet solid.

(iv) Other solid.

(v) Gas or vapor.

(vi) Liquid.
