The Future Is Now for TSCA Risk Management Rulemaking for Asbestos and Other Chemicals

EPA has proposed a ban on the continuing makes use of of chrysotile asbestos, illustrating EPA’s robust authority underneath part 6 of the Poisonous Substances Management Act (TSCA). Nonetheless, it’s the options to a ban that EPA thought of however didn’t undertake which have essentially the most implications for firms that make or use different chemical compounds for which EPA is conducting threat evaluations. The proposal heralds a brand new period of EPA promulgating a lot stricter office protections than OSHA has completed or that it might do underneath its statute.

That is the primary threat administration rule that EPA has proposed following a threat analysis for the reason that 2016 amendments to TSCA. The proposed rule, 87 Fed. Reg. 21706 (Apr. 12, 2022), would add Subpart F to 40 C.F.R. Half 751. Feedback are due by June 13, 2022.

1. The Proposed Asbestos Ban

EPA banned primarily all makes use of of asbestos that weren’t then ongoing with a 2019 vital new use rule, 40 C.F.R. § 721.11095. The new proposed rule would ban the continuing makes use of.

The proposed rule would prohibit the manufacture, together with import, processing, distribution in commerce, and industrial use of bulk chrysotile asbestos for, or as a part of, chrysotile asbestos diaphragms used within the chlor-alkali business and chrysotile asbestos-containing sheet gaskets utilized in chemical manufacturing. These prohibitions would take impact two years after the efficient date of the ultimate rule.

It will additionally ban the identical actions for chrysotile asbestos-containing brake blocks used within the oil business; aftermarket automotive chrysotile asbestos-containing brakes/ linings; different chrysotile asbestos-containing car friction merchandise (not together with the NASA Tremendous Guppy Turbine plane use); and different chrysotile asbestos-containing gaskets.

The proposed rule would prohibit the manufacture (together with import), processing, and distribution in commerce of aftermarket automotive chrysotile asbestos-containing brakes/linings for client use, and different chrysotile asbestos-containing gaskets for client use. These prohibitions would every turn out to be efficient 180 days after the ultimate rule’s efficient date.

Corporations that import chrysotile asbestos, aside from in articles, must be sure that their import certifications take the chance administration rule under consideration in certifying compliance with TSCA. Due to the SNUR, the export of chrysotile asbestos has already turn out to be topic to export notification necessities, even when the chrysotile asbestos is manufactured, processed, or distributed in commerce solely for export from america.

This proposed rule follows the TSCA part 6(b)(4)(A) risk evaluation for chrysotile asbestos accomplished in December 2020. EPA decided there that chrysotile asbestos presents an unreasonable threat of harm to well being or the surroundings. TSCA requires EPA, following such a discovering, to concern a rule underneath part 6(a), with out consideration of prices or different non-risk elements, in order that the chemical substance now not presents such threat underneath the situations of use.

2. Implications for Other Chemicals Present process Risk Evaluations

This proposed rule gives appreciable insights into EPA’s deliberate method for different chemical compounds following their threat evaluations.

Part-out intervals for a ban

Requests by business for lengthy phase-out intervals should be substantiated. Asbestos business stakeholders had voiced concern concerning the proposed deadlines, emphasizing that changing chrysotile asbestos-containing diaphragms will take longer than two years to exchange and that changing them will probably be extraordinarily costly. EPA acknowledged business concern however didn’t prolong the phase-out interval, noting that “these companies did not provide EPA with delineated cost estimates or a detailed timeline for the conversion process.” Other industries needs to be ready to current in depth information demonstrating the necessity for longer phase-out intervals in future part 6(a) rulemaking. EPA’s place on this proposed rule confirms EPA’s method within the PIP (3:1) rulemaking, which restricted the present compliance deadline for articles of October 31, 2024, regardless of business assertions that rather more time is required to take away PIP (3:1) from imported articles.

Anticipate EPA to complement CPSC and OSHA requirements. 

Below TSCA part 9(a), EPA should think about whether or not one other federal company can adequately handle the chance; in that case, EPA should defer to that company. The preamble means that EPA is more likely to conclude that the Client Product Security Fee (CPSC) and Occupational Security and Well being Administration (OSHA) can by no means handle the dangers of a chemical reviewed by EPA in a threat analysis adequately, in mild of TSCA’s 2016 amendments. Below its statutes, CPSC should think about prices and advantages in deciding whether or not a threat is unreasonable, whereas EPA should ignore prices and advantages in its unreasonable threat determinations. CPSC should implement the least burdensome various, whereas the 2016 amendments deleted that requirement from TSCA. EPA should shield populations not topic to OSHA necessities (resembling self-employed individuals and state and native authorities staff in states topic to OSHA jurisdiction). OSHA could solely impose restrictions to the extent that they’re economically and technologically possible, whereas EPA should think about feasibility however should impose restrictions to the extent {that a} chemical doesn’t current an unreasonable threat.

Anticipate TSCA publicity limits to be way more stringent than these of OSHA.

The preamble defined that EPA thought of imposing an “existing chemical exposure limit” (ECEL) for asbestos. EPA has beforehand used “new chemical exposure limits” (NCELs) in some TSCA part 5(e) orders and vital new use guidelines (SNURs).

The ECEL would have successfully supplanted OSHA’s permissible publicity restrict (PEL) in its asbestos customary, 29 C.F.R. § 1910.1001(c). OSHA’s PEL is 0.1 fiber per cubic centimeter (f/cc) as an 8-hour time-weighted common (TWA). That can be the Nationwide Institute for Occupational Security and Well being (NIOSH) Advisable Publicity Restrict (REL), Cal/OSHA PEL, and the American Convention of Governmental Industrial Hygienists (ACGIH) Threshold Restrict Worth (TLV). EPA’s ECEL would have been 0.05 f/cc TWA, or 95% decrease than the OSHA PEL, NIOSH REL, Cal/OSHA PEL, and the ACGIH TLV. EPA’s motion stage would have been half the ECEL, or 0.025 f/cc. EPA acknowledged that “[i]t is also unknown whether facilities could, under the ECEL provision, routinely monitor at or below the ECEL or ECEL-action level with reasonable certainty.” 

EPA claimed that it calculated its ECEL primarily based on a ten-4 threat stage, so it isn’t primarily based on a extra stringent threat stage than that utilized by OSHA. The distinction seems to be primarily based on EPA’s completely different statutory necessities, in that the feasibility of compliance isn’t a crucial issue.

The subsequent proposed threat administration rule to be introduced is more likely to be for methylene chloride. As with asbestos, OSHA has a full well being customary for methylene chloride. The OSHA PEL for methylene chloride is 25 ppm (8-hour TWA), with a short-term publicity restrict (STEL) of 125 ppm. 29 C.F.R. § 1910.1052(c). OSHA additionally has full well being requirements for 1,3-butadiene and formaldehyde, high-priority substances which might be the themes of ongoing threat evaluations. The OSHA PEL for 1,3-butadiene is 1 ppm (8-hour TWA), with a 5 ppm STEL. 29 C.F.R. § 1910.1051(c). The OSHA formaldehyde PEL is 0.75 ppm (8-hour TWA), with a STEL of two ppm. 29 C.F.R. § 1910.1048(c). If the eventual threat administration guidelines for these chemical compounds don’t ban them, the foundations could have sharply decrease publicity limits than these of OSHA.

Anticipate PPE utilization to be ignored in setting publicity limits.

EPA calculated its 10-4 threat stage on the belief of no use of private protecting tools (PPE). It said that PPE is usually, however not at all times, utilized by individuals uncovered to asbestos. Since EPA should shield even teams who could also be at better threat via better publicity (citing the TSCA part 3(12) definition of “potentially exposed or susceptible subpopulation”), EPA felt it mustn’t think about PPE use in setting a threat stage. EPA did point out that PPE use might complement engineering and work follow controls to attain compliance with the ECEL. Moreover, the preamble stated, “EPA can use the information developed during its risk evaluation to determine whether the alignment of EPA’s risk management requirements with existing OSHA requirements or industry best practices will adequately address unreasonable risk as required by TSCA.” Thus, in EPA’s view, proof of precise PPE use is of worth to EPA, however solely as displaying the efficacy of EPA-required mitigation measures, not in its place for such mitigation measures.

Anticipate monitoring necessities to be extra stringent than these of OSHA.

Monitoring could be extra burdensome than that underneath OSHA, partially as a result of it will require compliance with Good Laboratory Practices. Based on the preamble, “underneath the first various regulatory motion, EPA would require the usage of applicable sampling and analytical strategies to find out asbestos publicity, together with:

  • Use of analytical methodology with a restrict of detection beneath the ECEL-action stage,

  • Compliance with the Good Laboratory Apply Requirements at 40 CFR half 792;

  • Documentation of knowledge relating to air monitoring tools, together with Upkeep, efficiency assessments, limits of detection, and any malfunctions.”

Exemptions for substitute components and articles should not assured.

TSCA part 6(c)(2)(D) requires EPA to exempt substitute components except EPA finds that substitute components “contribute significantly to the risk.” Equally, part 6(c)(2)(E) permits EPA to limit chemical compounds in articles “only to the extent necessary to address the identified risks” from the articles themselves. The proposed asbestos rule wouldn’t exempt both substitute components or articles from the ban, because of the asserted potential for publicity to asbestos coming from these articles. Thus, for EPA to grant exemptions for substitute components or articles in future threat administration guidelines, business would wish to reveal that the necessities for the exemptions are met primarily based on data within the rulemaking report.


The proposed asbestos threat administration rule has implications far past asbestos. Stakeholders for different chemical compounds being reviewed underneath TSCA part 6 can anticipate EPA ultimately to contemplate proposing restrictions way more stringent than these of OSHA. They need to work to make sure that the rulemaking report helps a conclusion that present OSHA necessities are adequate to stop these chemical compounds from presenting an unreasonable threat, and, the place related, that the report helps exemptions for substitute components and articles.
