|TSCA: Toxic Substances Control Act|
A number of changes to the Act took effect on June 22, 2016; see the Frank R. Lautenberg Chemical Safety for the 21st Century Act information below.
TSCA applies to organizations that involve the manufacture, processing, distribution in commerce, use, and/or disposal of a new or existing chemical substance or mixture that may present an unreasonable risk of injury to health or the environment. The reporting threshold was raised in 2002 from 10,000 lbs (4,500 kg) to 25,000 lb (11,340 kg) per year. Most businesses that meet the 40 CFR 704.3 definition for small manufacturer or importer are exempt from reporting requirements. A business meets that criterion when total annual sales are less than $40 million and the manufacturing or import volume is less than 100,000 pounds (45,360 kg) at all sites.
By definition, TSCA-regulated chemical substances and mixture do not include "...any source material, special nuclear material, or byproduct material (as such terms are defined in the Atomic Energy Act of 1954 and regulations issued under such Act)..." [TSCA, Section 3(2)(B)(iv)]. Although TSCA excludes nuclear material, the TSCA-regulated portion of a mixed nuclear and regulated waste must comply with TSCA requirements. Materials that are not chemical substances or mixtures are not subject to the requirements of TSCA.

A TSCA report for 25,000 lbs or more includes:
For substances with annual volumes of 300,000 lbs (136,000 kg) or more per site, significant additional information is also reported.

Under the Inventory Update Rule (IUR) the TSCA inventory is updated every 5 years. Prior to 2006, the update period was 4 years. Some new changes included in the 2002 update were:|
The idea of the higher reporting limit is to reduce the additional burden associated with covering more chemicals. As one might expect, both chemical manufacturers and community/environmental groups like some of these changes more than others!
The EPA's ability to ban chemicals under the original implementation of TSCA was a dismal failure. Only five chemicals were ever explicitly banned. In 1989, after ten years of study and spending ten million dollars, EPA issued a Final Rule which banned asbestos, a known and potent human carcinogen for which there are multiple and far safer alternatives and removal of which is so dangerous that it is governed by an array of safety regulations. However, the Final Rule was vacated in 1991 in an absurd court ruling that TSCA required the EPA to prove it had analyzed every conceivable way of restricting asbestos and had chosen the "least burdensome alternative" to industry. EPA basically gave up on efforts to ban chemicals after that point, and to this very day, asbestos may still be legally included in a host of materials, which not only expose the workers who manufacture and install it, but also any unsuspecting person who unwittingly disturbs the material and releases asbestos fibers into the air.
In September of 2009, the Obama administration unveiled broad proposals to reform TSCA and give the EPA the ability to ban or restrict unsafe chemicals. Supporting legislation was announced by US Senators Frank Lautenberg (Democrat, NJ) and James Jeffords (Independent-VT) in 2010, but after a number of hearings and stakeholer sessions, the bill died amidst industry opposition. The EPA did announce its intention to reject a certain type of confidentiality claim, known as Confidential Business Information (CBI), on the identity of chemicals, but this minor change would do nothing to take unsafe chemicals off the market. After considerable effort, on June 22, 2016, the Frank R. Lautenberg Chemical Safety for the 21st Century Act was signed which made many needed improvements although it fell far short of the original goals. Under the revisions, the following changes were made:
A summary of all of the major changes is available at https://www.epa.gov/assessing-and-managing-chemicals-under-tsca/highlights-key-provisions-frank-r-lautenberg-chemical.
Critics of the Act point out that it is so watered down that the EPA will not begin testing chemicals for three years, and only then that will include only 3 solvents, 20 chemicals and asbestos, all of which were already on EPA's agenda, leaving 30,000+ high-production chemicals untested. Further, within days of the signing of the act, it became clear that politicians and other parties would begin demanding that the EPA give their personal concerns priority instead of letting the EPA do its job - determining which chemicals pose the greatest risk based on exposure levels, production volume, individual hazards, and known human health effects. Hopefully, the EPA will be able to resist these external attempts to disrupt the prioritization process which will focus on making the biggest impact on human health and the environment.
Some MSDS's may contain code letters that are used in the TSCA Inventory to identify substances that are the subject of an EPA rule or order promulgated under TSCA, or to indicate the a full or partial exemption from TSCA reporting requirements. These codes are not required to be on an MSDS. In our opinion, these codes are completely useless to the end user - why give a cryptic code instead of simply writing out what the code stands for?
|Note: Some of the letters/symbols used in this table are also used as CHIP, HMIS, and/or DoD HMIRS/HCC codes, all of which have completely different meanings and applications! See why we dislike code systems?|
|E||Subject to the Section 5(e) Consent Order of TSCA|
|F||Subject to the Section 5(f) Rule of TSCA|
|N||A polymer containing no free-radical indicator in its Inventory name but is made with one regardless of the amount used.|
|P||A commenced PMN (Premanufacture Notice) substance|
|R||Subject to a Section 6 risk management rule under TSCA|
|S||Substance is identified in a proposed or final SNUR (Significant New Use Rule) under TSCA|
|T||Subject to the Section 4 test rule under TSCA|
|XU||Exempt from reporting under the Inventory Update Rule|
|Y1||An exempt polymer that has number-average molecular weight of 1,000 or greater|
|Y2||An exempt polymer that is a polyester and is made only from reactants included in the specified list of low concern reactants in the exemption eligibility criteria rule|
