EPA Promulgates Direct Final SNURs under TSCA for Seventeen Chemicals

/in

TSCA:

On June 24, 2010, EPA promulgated significant new use rules (SNURs) under section 5(a)(2) of the Toxic Substances
Control Act (TSCA) for 17 chemical substances that were the subject of premanufacture notices (PMNs), the type of notice submitted prior to manufacturing or importing a “new chemical” for commercial purposes.  The Federal Register notice announcing the SNURs can be found at 75 Fed. Reg. 35977.

Two of the substances are subject to ‘‘risk-based’’ consent orders under TSCA section 5(e)(1)(A)(ii)(I) where EPA determined that activities associated with the substances may present unreasonable risks to human health or the environment.  The SNURs for these two substances are based on and consistent with the provisions in the underlying consent orders.  The 5(e) SNURs designate as a ‘‘significant new use’’ the absence of the protective measures required in the corresponding consent orders.

The other 15 substances are not subject to consent orders under section 5(e).  EPA did not find that the use scenarios described in their PMNs triggered the determinations set forth under TSCA section 5(e).  Nonetheless, the Agency concluded that certain changes from the use scenarios could result in increased exposures potentially causing adverse human health or environmental effects, or both, and thereby would constitute ‘‘significant new uses.’’

The Agency used its direct final rulemaking procedure to promulgate the SNURs, which means the rules will become effective on August 23, 2010, if EPA does not receive by July 26, 2010, written adverse or critical comments, or notice of intent to submit such comments.  In that instance, EPA would withdraw the SNUR for the substance(s) for which it received comments or notices, and instead it would issue a proposed SNUR and provide a 30-day public comment period.

A short overview of each substance, and the next steps some companies will likely consider, are set out below.

Overview of the Chemicals Affected

Persons who intend to manufacture, import, or process any of these 17 substances for an activity that is designated as a significant new use are required to notify EPA at least 90 days before commencing that activity. The required notification will give EPA the opportunity to evaluate the intended use and, if necessary, to prohibit or limit that activity before it occurs.

Each substance is listed below – typically with a generic name to protect Confidential Business Information (CBI) – along with the Code of Federal Regulations (CFR) citation to its respective SNUR, the PMN number, and the use(s) identified in its PMN.

Next Steps

First, many companies are probably determining whether they currently manufacture, import, or process any of these substances, or have plans to do so in the future.   If so, they may be assessing whether and how these rules would affect their business and deciding whether to submit comments to EPA by the deadline noted above.

Second, companies that import any of these substances are likely confirming that they are prepared to make the necessary import certifications.  TSCA section 13 (15 U.S.C. 2612) requires importers to certify that each shipment of a chemical substance complies with all applicable rules and orders under TSCA.  Importers of chemical substances subject to a final SNUR must certify their compliance with the SNUR requirements.  The import certification requirements are set out in the regulations at 19 CFR 12.118 – 12.127, and 127.28 (the corresponding EPA policy is codified at 40 CFR part 707, subpart B).

Lastly, companies may also be confirming that they are prepared to make the necessary export certifications.  In general, any person who exports or intends to export a chemical substance that is the subject of a proposed or final SNUR is subject to the export notification provisions of TSCA section 12(b) (15 U.S.C. 2611(b)) and the regulations at 40 CFR part 707, subpart D. The export notification requirements apply even when a company does not manufacture, import, or process the substance in a manner restricted by the SNUR.  The notification requirement applies regardless of whether the company is required to take any action under the SNUR.

TSCA CBI – New Practices Adopted at EPA While Further Changes Are Debated in Congress

/in ,

TSCA, TSCA Reform: 

Confidential Business Information (CBI) continues to be a focal point of the debates over improving implementation of the current version of TSCA, as well as amending the statute.  Here’s a short update on where those debates currently stand.

EPA Adopts New Practices under TSCA

On May 27, 2009, EPA announced in a Federal Register notice that the Agency will begin a “general practice” of reviewing CBI claims for chemical identities in health and safety studies and related data, submitted under TSCA in accordance with EPA regulations at 40 C.F.R. Part 2, Subpart B.  According to the notice, “Section 14(b) of TSCA does not extend confidential treatment to health and safety studies, or data from health and safety studies, which, if made public, would not disclose processes used in the manufacturing or processing of a chemical substance or mixture or, in the case of a mixture, the release of data disclosing the portion of the mixture comprised by any of the chemical substances in the mixture.” If the chemical identity does not clearly reveal mixture portions or process information, EPA is unlikely to find the information eligible for confidential treatment.  EPA will apply its new practice to both newly submitted and existing claims, beginning August 25, 2010. 

Stakeholders supporting or opposing this new practice are likely to submit comments to the Agency in advance of the August implementation.

Congressional Debate over the Bills to Modernize TSCA

Both the Senate and House bills would revise and narrow the protections for CBI.  The bills would require all CBI claims to be justified up front.  EPA would have to review the claims within a prescribed time period.  Only those that withstood the review – applying standards that EPA would adopt within one year of enactment of the legislation – would be eligible for protection.  Approved claims would receive protection for up to five years. 

Similar to the current version of Section 14, the bills would not allow “the release of any data which discloses processes used in the manufacturing or processing of a chemical substance or mixture or, in the case of a mixture, the release of data disclosing the portion of the mixture comprised by any of the chemical substances in the mixture.” Nonetheless, the chemical industry remains concerned about the negative impact the new CBI provisions would have on innovation, jobs, and the U.S. industry’s general competitiveness.   ICIS reports that the CEOs from 30 different chemical companies planned to meet this past Wednesday with 50 different members of Congress or their staff to discuss the bills, and the CBI provisions concerning chemical identities were on the top of their list of concerns.

EPA Expands Public Access to Information on Chemicals

/in

TSCA:

On May 17, EPA issued a press release, announcing that it had added more than 6,300 chemicals and 3,800 facilities, regulated under the Toxic Substances Control Act (TSCA), to the public database known as Envirofacts.   The Agency said its action further demonstrated Administrator Lisa Jackson’s commitment to increasing public access to information on chemicals.   

The Envirofacts database is available on EPA’s website.  The database is designed to provide information on facility activities that may affect air, water, and land in the United States.   Included in the database is information such as facility name and address, aerial imagery, maps, and links to other records such as those available on the Agency’s Enforcement Compliance History Online (ECHO) database, which provides inspection and compliance reports.

In the press release, EPA stated that it has conducted a series of efforts to increase public access to chemical information including reducing confidentiality claims by industry and making the public portion of the TSCA inventory available for free on its website.  EPA supposedly intends to take additional actions in the months ahead to further increase the amount of information available to the public.  Additional details regarding EPA’s plans are available here.

I plan to continue following and reporting on EPA’s public-access initiative, as well as the confidential business information (CBI) provisions in the Congressional bills proposing to modify TSCA.  Stay tuned for future postings here at The Green Chemistry Law Report!
