Lead Wheel Weights; Regulatory 
Investigation Under the Toxic Substances Control Act (TSCA) 
AGENCY : Environmental Protection 
Agency (EPA). 
ACTION : Advance notice of proposed 
rulemaking (ANPRM). 
SUMMARY : The Environmental Protection 
Agency (EPA or the Agency) is requesting comments and information to assist in the potential development of regulations for the manufacture (including importing), processing (including recycling), and distribution in commerce of lead for wheel- balancing weights (‘‘lead wheel weights’’) under the Toxic Substances Control Act (TSCA). To inform this consideration, EPA is requesting comment and information from all stakeholders on the use and exposure to lead from the manufacture (including importing), processing (including recycling), distribution in commerce, use, and disposal of lead wheel weights, as well as information on their substitutes, to help determine if there is unreasonable risk to human health and the environment associated with this use. This action is relevant to a petition for a writ of mandamus filed in August 2023, by the Ecology Center, Center for Environmental Health, United Parents Against Lead & Other Environmental Hazards, and Sierra Club in the United States Court of Appeals for the Ninth Circuit requesting the court to direct EPA to conduct a rulemaking regulating 
lead wheel weights under TSCA.

B. What is the Agency’s authority for taking this action? 
This action is being taken under the 
Toxic Substances Control Act, 15 U.S.C. 2601 et seq. 
TSCA section 21 allows citizens to 
petition EPA to initiate a rulemaking proceeding for the issuance, amendment, or repeal of a rule under TSCA sections 4, 6, or 8 or an order under TSCA sections 4 or 5(e) through (f). If EPA grants such a petition, the Agency must promptly commence an appropriate proceeding. 
Under TSCA section 6(a), if EPA 
determines that the manufacture, processing, distribution in commerce, use, or disposal of a chemical substance presents an unreasonable risk to human health or the environment, it must ‘‘apply one or more of the [TSCA section 6(a)] requirements . . . to the extent necessary so that the chemical substance . . . no longer presents such risk,’’ which may range from prohibiting or otherwise restricting the manufacturing, processing, or

distribution in commerce of the 
chemical substance (or a particular use), to commercial use requirements or disposal restrictions, to labeling and recordkeeping. 
C. What action is the Agency taking? 
Through this ANPRM, EPA is seeking 
comment and information on specific 
issues regarding potential exposure to lead during manufacturing, processing (including recycling), distribution in commerce, use, or disposal of lead wheel weights, as well as information on substitutes for lead wheel weights. This information will help inform the Agency’s determinations regarding potential unreasonable risk to human health and the environment from exposure to lead wheel weights. If unreasonable risk is determined, EPA will initiate a proposed rulemaking under TSCA section 6(a) to address the unreasonable risk. 
D. What are the incremental costs and 
benefits of this action? 
This action does not impose or 
propose any requirements, and instead seeks comments and suggestions that will help the Agency identify whether and to what extent there is a potential need for a TSCA section 6 rule and/or other administrative action. If EPA decides to propose a rule, it will conduct the appropriate assessments of the costs and benefits of those changes and provide opportunities for public comment. 
E. What should I consider as I prepare 
my comments for EPA? 
1. Submitting CBI. Do not submit CBI 
to EPA through https://www.regulations.gov or email. If you 
wish to include CBI in your comment, please follow the applicable instructions at https://www.epa.gov/dockets/ 
commenting-epa-dockets#rules and 
clearly mark the information that you 
claim to be CBI. Information so marked will not be disclosed except in accordance with procedures set forth in 40 CFR parts 2 and 703.

II. Background A. 2009 TSCA Section 21 Petition 
In May 2009, Sierra Club, Ecology 
Center, and several other non- 
governmental organizations submitted a TSCA section 21 petition requesting EPA ‘‘to establish regulations prohibiting the manufacture, processing, and distribution in commerce of lead wheel balancing weights (‘wheel 
weights’)’’ (Ref. 1). Petitioners raised concerns that lead wheel weights result in pervasive lead exposure to children. EPA acknowledged receipt and requested public comment on the petition on July 15, 2009 (74 FR 34342 (FRL–8424–7)). EPA granted the petition on August 26, 2009 (Ref. 2). EPA has not issued any regulatory action relating to this petition since granting the petition. 
B. 2023 Writ of Mandamus 
In August 2023, Ecology Center, 
Center for Environmental Health, 
United Parents Against Lead & Other 
Environmental Hazards, and Sierra Club sought a writ of mandamus in the United States Court of Appeals for the Ninth Circuit and asked the court to direct EPA to conduct a rulemaking regulating lead wheel weights under TSCA section 6. 
C. What are lead wheel weights? 
Wheel weights are small pieces of 
metal or other material used to correct 
imbalances in the weight distribution of motor vehicle tires. Lead has historically been a primary component of many wheel weights because of its malleability, high density, and relatively low cost. These wheel weights can separate from the wheel due to failure of the adhesive or clip attaching them, or due to impact of the wheel with a pothole or road debris or during a crash, or due to other chronic and acute strains. Lead wheel weights that separate from vehicle wheels, or are not properly disposed of, may be a source of lead exposure to humans and the environment under various circumstances (Ref. 3), for example by being ground into fine particles by traffic. Additionally, there may be lead exposures associated with manufacturing, processing, distribution, recycling, or disposal of lead wheel weights. 
III. Request for Comment and 
Information 
EPA is providing this opportunity for 
the public to comment on or provide any additional information relevant to the use of and exposure to lead from the manufacture (including importing), processing (including recycling), distribution in commerce, use, and disposal of lead wheel weights. In order for the Agency to consider such comments, EPA must receive the comments by the date indicated under 
DATES . In particular, EPA seeks 
information on the following: 
1. Quantitative information, data and/ 
or case examples (e.g., recent scientific 
and technical studies, including datasets, analyses of environmental impacts, and statistical analyses) associated with lead releases to air, surface water, ground water, soil, dust, and any other environmental medium (particularly regarding releases within one mile of roadways, communities near industrial sites, and releases to sensitive human and ecological populations) from the manufacture, processing (including recycling), distribution in commerce, use, or disposal of lead wheel weights. 
2. Quantitative information, data and/ 
or case examples (e.g., recent scientific 
and technical studies, including datasets, analyses of environmental impacts, and statistical analyses) associated with plastic or metal releases to air, surface water, ground water, soil, dust, and any other environmental medium (particularly regarding releases within one mile of roadways, communities near industrial sites, and releases to sensitive human and ecological populations) from the manufacture, processing (including recycling), or distribution, of lead wheel weight alternatives including: steel wheel weights; zinc alloy wheel weights; plastic metal composite wheel weights; mercury wheel balancing weights; and tin wheel weights. 
3. Quantitative information on the 
relative and absolute bioavailability of lead from new and/or weatherized lead wheel weights. 
4. Information on potential human 
and ecological exposure routes associated with lead releases from the manufacture (including importing), processing (including recycling), disposal and distribution in commerce of lead wheel weights, including residential exposures associated with take-home of lead from occupational sites by workers who manufacture, process, or dispose of lead wheel weights. 
5. Information on the current 
availability and suitability of lead-free wheel weights as alternatives, in both original equipment and aftermarket settings, particularly any comparisons between lead-free and lead wheel weights in terms of price, ease of installation, durability, and other attributes of performance and suitability. 
6. Information on the comparative 
lead weight by product and use rate of lead and lead-free wheel weights, both in original equipment and aftermarket settings over time, and information on the comparative use rate of clip-on versus adhesive wheel weights. 
7. Information on the chemical 
composition of lead and lead-free wheel weights including percentages of lead

and other constituents by weight, such 
as zinc and mercury. 
8. Quantitative information and data 
about the volume of lead wheel weights imported to the United States relative to lead wheel weights manufactured domestically. 
9. Quantitative information and data 
(e.g., recent scientific and technical 
studies, including statistical analyses) on the loss or failure rate of lead, non- lead, clip-on, and adhesive wheel weights (i.e., the rate at which wheel 
weights fall off of vehicle wheels onto roadways). 
10. Quantitative information and data 
(e.g., recent scientific and technical 
studies, including statistical analyses) 
on the abrasion or decomposition rate of both clip-on and adhesive lead wheel weights on roadways, including the rate at which abraded lead dust may migrate to other media including road dust, soil, and air. Additionally, data on other mechanisms for removal of wheel weights from roadways including the rate of wash-out by rainfall, removal by street sweeping, ejection from the roadway by vehicle impact, etc. 
11. Quantitative information and data 
(e.g., recent scientific and technical 
studies, including statistical analyses) on the geographical distribution of dislodged lead wheel weights in terms of proximity to population centers (e.g., differences between urban and non- urban environments) along with information on possible ingestion of lead wheel weights by children living in these urban centers. 
12. Quantitative information and data 
(e.g., recent scientific and technical 
studies, including statistical analyses) relating to occupational hazards and exposure associated with the manufacture(including importing), processing (including recycling), and distribution in commerce of lead wheel weights including workplace lead exposure from air/inhalation, dust ingestion, dermal contact, potential take-home exposures and blood lead levels of workers exposed to lead wheel weights, such as workers at entities outlined above, as well as transportation construction, management, or maintenance workers (e.g., street 
cleaning, road repair, and auto repair), including those in auto shops that install and remove lead wheel weights. 
13. Information and data (e.g., recent 
scientific and technical studies, including statistical analyses) related to hazards and exposures associated with the collection of and repurposing of lead wheel weights by home hobbyists, including information related to practices for at-home melting and lead recasting activities (e.g., frequency, 
duration, quantity of lead melted and recast, temperatures used, sociodemographic characteristics of the subpopulations engaged in these practices, as well as the form in which the weights are repurposed), data on impacts to children’s health, and associated contamination of air, dust, soil, and other environmental media, as well as contamination on surfaces (e.g., clothes and furniture).

statutes and Executive Orders can be found at https://www.epa.gov/ regulations/and-executive-orders. 
A. Executive Order 12866: Regulatory 
Planning and Review and Executive Order 14094: Modernizing Regulatory Review 
This action is not a significant 
regulatory action as defined in Executive Order 12866 (58 FR 51735, October 4, 1993), as amended by Executive Order 14094 (88 FR 21879, April 11, 2023), and was therefore not subject to a requirement for Executive Order 12866 review. 
B. Other Regulatory Assessment 
Requirements 
Because this action does not impose 
or propose any requirements, and instead seeks comments and suggestions for the Agency to consider in possibly developing a subsequent proposed rule, the various other review requirements in statutes and Executive Orders that apply when an agency imposes requirements do not apply to this ANPRM. Should EPA subsequently determine to pursue a rulemaking, EPA will address the requirements in the statutes and Executive Orders as applicable to that rulemaking.
