Statistics for the New Chemicals Review Program under TSCA
On June 22, 2016, the Frank R. Lautenberg Chemical Safety for the 21st Century Act amended the review of new chemical notices under section 5 of the Toxic Substances Control Act (TSCA). This page provides a summary of the submissions received and actions taken under TSCA before and after the date of enactment.
Statistics under Amended TSCA
EPA has successfully addressed the backlog of manufacturers’ new chemical requests or pre-manufacturing notices (PMNs) under review by the Agency so that the number of cases under review is back to historically typical levels. To achieve this, EPA deployed new staff and made other process changes to make the process faster and more efficient, while ensuring chemical safety. EPA continues to work with manufacturers to ensure the Agency has all the information necessary to assess a new chemical’s safety.
At any one time, EPA typically has an average of 300 new chemical cases under review. As the Agency makes final determinations on chemicals already in the review process, decreasing the case load, new requests are being submitted which increases the case load. With the new law's passage cases in the review pipeline on June 22, 2016 needed to be reassessed under the new statutory requirements, adding to the Agency’s average case load and creating a “backlog” which grew to almost 600 cases.
The current caseload of cases includes a number of cases in which submitters are developing information or conducting testing. If these cases are subtracted from the total, the number of new chemicals cases under active review by EPA is now consistent with the normal active workload of cases for the new chemicals review program.
Overall, since the law’s passage, EPA has completed determinations on 1,593 new chemical cases. Details on the Agency’s determinations are displayed below. EPA will continue to add new content, on a weekly basis, in an effort to be more transparent to the public on the status of the Agency's reviews and to allow submitters to determine the disposition of their cases as quickly as possible. EPA is committed to working with PMN submitters early in the process to provide more certainty and to begin any necessary discussions earlier in the process with the expectation that submitters and EPA can work together to decrease the time needed to complete each review.

|Exemptions cases withdrawn||42|
|Total Exemption Reviews Completed||827|
|Notices of Commencement (NOCs) to Manufacture***|
|Number of NOCs Received||548|
** The typical caseload under review is approximately 300 cases.
*** Frequently, when a company is allowed to commercialize (with or without restrictions) the company does not immediately begin to manufacture.
When manufacture does commence, the submitter must provide a Notice of Commencement of Manufacture or Import Form (NOC) to EPA within 30 calendar days of the date
when the substance is first manufactured or imported for nonexempt commercial purposes.

***The number of NOCs received during the listed Fiscal Year
Approximately 10 percent of the 39,000 total PMN submissions have resulted in issuance of section 5(e) consent orders that impose various restrictions and testing requirements, and notices withdrawn in the face of regulation. For exemption notices, EPA can grant or deny the notice, with or without certain conditions of use specified in the notice, to which the submitter is legally bound.
Section 5(e) Consent Orders
More than 1,700 of all new chemicals submitted as PMNs have been subject to consent orders under TSCA section 5(e). Such "section 5(e) consent orders" serve to limit the production, processing, distribution in commerce, use, and disposal of new chemical substances that raise health or environmental concerns, pending receipt of required information.
Significant New Use Rules (SNURS)
A subset of 739 of the above-mentioned consent orders have associated with them a SNUR, issued by EPA under TSCA section 5(a)(2). In general, these SNURs mimic the Consent Order to bind all other manufacturers and processors to the terms and conditions contained in the Consent Order. For such chemical substances, persons are required to submit a Significant New Use Notice (SNUN) to EPA at least 90 days before they manufacture, import, or process the substance for the use designated as significant. The required SNUN provides EPA with the opportunity to evaluate the intended use, and if necessary, to prohibit or limit that activity before it occurs.
In addition to these 739 SNURs, an additional 1,457 new chemical substances were regulated by EPA with SNURs which require notice to EPA for potential new uses of the chemical (other than those reviewed as part of the PMN) that may pose unreasonable risks.
In more than 2,000 cases, companies have withdrawn PMNs in the face of EPA concerns and likely regulatory requirements.
