action: Advance Notice ofProposed Rulemaking.___________________ .
summary: The Consumer Product Safety Commission is concerned that consumer exposure to asbestos from consumer products may present an unreasonable risk of injury and that some consumer products containing asbestos may present a substantial product hazard. CPSC will begin its formal investigation, of the use of asbestos in consumer products by publishing this notice soliciting general information on the use of asbestos in consumerproducts. In addition to soliciting information bn the use of asbestos ta consumer products, this notice describes CPSCs proposed regulatory approach to asbestos in consumer products and solicits public comment on the approach. The Commission will consider the comments during the development of any proposed regulation or other remedial action to protect consumers.
date: Comments and information should be submitted on or before December 17,1979. Those comments received after this date will be considered only to the extent practicable.
ADDRESS: Comments and information should be sent, preferably in five copies,, to Office of the Secretary, Consumer Product Safety Commission. Washington. D.C. 20207. and should refer to "Asbestos." Received comments and other relevant information may be examined in copies obtained from Office of the Secretary, 1111 18th Street. N.W., 3rd Floor, Washington. D.C. 20207, during business hours Monday through * Friday.

Information Gathering on Consumer Products Containing Asbestos ' '
In order to determine the scope of the potential problem posedjry consumer products containing asbestos, CPSC commissioned a study to determine what other categories of consumer products contain asbestos. As a result of a report by a Commission contractor. Review ofAsbestos Use in Consumer Prducts, A. T. Kearney, Inc., Management Consultants (April, 1978) (Kearney report) and through examination of other published sources,
the Commission has developed information that indicates the presence of asbestos in a number of consumer products. Using the Kearney report and other available published sources, the Commission's staff has grouped the products according to die general form in which the asbestos exists in the product. This list of consumer products or categories of products containing asbestos is set forth in Appendix A to this notice. Also included in Appendix A is a list of consumer products dial have' been the subject of consumer inquiries or that are otherwise alleged to contain

RegulatoryApproach
General Policy
The previous regulatory action the Commission has taken concerning asbestos in cpnstutier products has been based on several principles. First the Commission concluded that exposure to any respirable asbestos fibers from consumer products presents a health risk because there has not been demonstrated to be a threshold or no effect level below which exposure to asbestos fibers would be considered safe. Further, exposure to asbestos from consumer products is generally in addition to environmental exposure from a number of other sources, and therefore must be viewed as part of a cumulative burden of asbestos exposure.
Second, the seriousness of the injury associated with asbestos exposure--the potential increased risk of cancer--was given considerable weight by the Commission in the decision-making process to determine whether the consumer products presented an unreasonable risk. As it is required to do by statute, the Commission carefully considered the effect of regulatory action on the utility, cost and availability of the product and concluded that in the absence of compelling evidence of unacceptable social or economic costs associated with removal of asbestos from the product, regulatory action was warranted.
The Commission recognizes that before it may take regulatory action, the Commission must make the necessary statutory findings, based on substantial evidence; and that it must observe the requisite procedures designed to ensure due process in-taking regulatory action.
As a general approach, however, the Commission proposes initially to seek the elimination of all non-essential uses of asbestos in consumer products from which asbestos fibers are released during reasonably foreseeable conditions of use, including misuse. The Commission proposes to take regulator)' action concerning non-essential uses of

Consistent with their J legislative mandates, existing' " regulations,are limited to controlling asbestos in specific itiedia (e.g.. air, water, foodlsource categories (ejg.. process emissions, waste piles), or . population segment* (e*. workers). These regulatidns are not designed to control tje full range ofexposure ,, situatiorisFor example, there are over 100 million motor vehicles in the.Uaited Slates today- Since most vehicles use a set of asbestos-containing brakelinings every 3 or 4 years, a considerable amount ofosbestbs-coabUniag material is released to the environment during use and maintenance. Yet. not Federal regulation addresses the problem of asbestosbuild-upin tiiebiosphere from this and many other souroes.
Even within their regulatory purviews. Federal and state authorities are constrained, to establishing adequate asbestos exposure controis- Because of their limited focus', these authorities only weigh partial risks (e.goccupational exposure) against total societal benefits ofasbestos-contalning products and uses. Hie limitations of available fiber measurmenl techniques also constrain the range of feasible control options.
Approach to Regulation of Asbestos Under TSCA
The Agency believes that TSCA provides an effective means of controlling the proliferation of asbestos use to the United States and of reducing the health risks associated withthe existing accumulation of asbestos to the environment. Under the oompreshensive jurisdiction of TSCA. EPA has authority to weigh overall risks presented by the entire asbestos life cycle, from mining to final disposal For example. EPA can controlanychemical manufacturing, processing, distribution to commerce, use. or disposal activity, or any combination of these activities found to pose an unreasonable risk to health and the environment EPA is planning to use TSCA'a unique authority to this rulemaking to assess whether exposure to asbestos throughout its life cycle presents an unreasonable risk to human health. Where the presence of risk is determined, EPA will consider developing regulations under TSCA and other laws which the Agency administers. The development of

regulations under TSCAandother authorities Will be integrated to promote adequate health protection and minimize impacts on industry.
The Agency anticipates that most asbestos regulatory action will be taken under section 6(a) of TSCA. although section 5(a) might also be used where appropriate. Among other tilings, section 6(a) enables the Agency to restrict ,,, chemical processing, limit quantities that can be used, require appropriate labels, and mandate recordkeeping. Section 5(a) enables the Agency to require that manufacturers submit premanufacturing notification for significant new uses of a chemical.
Before promulgating a rule under section 6(a) of TSCA, the Administrator must determine that the substance in question presents an unreasonable risk to human health and the environment The Agency can then develop rules to reduce or prevent the risk using the least burdensome requirements.
To accomplish this end in the case of asbestos. TSCA requires that the
following areas be examined and documented:
(1) The seriousness of health effects associated with identified levels and durations of human exposure to asbestos;
(2) The benefits of various uses of ' asbestos and the availability of practical substitutes for these uses; and
(3) The reasonably ascertainable economic impacts of tHe rules on the national economy, small business, technological innovation, the
environment and public health. The following sections discuss the
method the Agency plans to use in carrying out these studies.
Risk Assessment
EPA is examining the total risk to human health from exposures to asbestos throughout the material's commercial life cycle (Le., from mining and milling, through fabrication into products, to final use and ultimate disposal). The Agency is preparing an assessment of occupational and general population risks from both new and existing exposure sources. The investigation will be based principally on available data concerning asbestosrelated health effects and potential exposure situations. EPA believes that it already has much data to support, rulemaking under TSCA. However, to insure that all relevant information is considered, the Agency expects to
propose a reporting rule under section 6(d) of TSCA. The rule will require submission to the Agency of any unpublished health and safety studies on asbestos.

Federal Register ] VoL 44. No. 202 } Wednesday. October 17. 1979 j Proposed Rules
Regulatory ControlOptions
The Agency te considering the following regulatory approaches to prevent and reduce unreasonable health
risks at all stages of the asbestos life
cycle. First, the Agency might promulgate
prohibitions on the manufacture, processing, and use of specificasbestos* containing products or product / categories. The products or categories to be controlled would be determined on the basis of a category orproduct specific analysis of socioeconomic
factors. Possible controls might include banning the manufacture and use of asbestos-containing textiles, roofing paper, or brake linings.
One disadvantage ofthis approach
stems from asbestos fiber demand which reportedly exceeds current -
supplies. If this situation persists, fibers orginaliy destined for a banned product might be transferred to increase
production of unrestricted products. Such a transfer could offsetthe reduction in asbestos-use anticipated under the product use ban, The situation would only change after a large number of asbestos-oontaining'products and uses were banned.
Another disadvantage of the specific product restriction approach is thatit could generate voluminous exemption'' requests. Although well defined exemption criteria could minimize the number of requests, the demand on EPA resources could be significant. Despite * these drawbacks, this option should stiD enable EPA to reduce and prevent many exposures associated with nonessential asbestos products.
Under the second approach, EPA could promulgate regulations setting limits on the amount of asbestos mined in the United States and imported annually. Alternatively, the regulation could restrict the amount of asbestos processed annually in the United States.
The net risk reduction and prevention from either alternative should be about the same, in selecting betweenthem. EPA would consider such factors as economic impacts and resources
necessary for enforcement Either alternative within this approach would be supported by a general or representative socioeconomic analysis of the proposed asbestos controls.
In essence, the second approach would establish a ceiling on the amount of asbestos used in the United States. This ceiling could be reduced gradually until it reaches a level which the
Agency's socioeconomic analysis indicates is necessary for essential asbestos-containing products and uses. This approach would allow industry to
determine which products and uses to
eliminate. EPA would still be assured of

exposure to asbestos emissions from brake linings occurs not only during processing (i.e. production of the brake .linings), but also during use and servicing of brakes. Several automobile manufacturers are already using nonasbestos disc brake pads with plans to ultimately convert totally to nonasbestos pads. Nonasbestos shoes for drum brakes have been more difficult to develop but some manufacturers believe that they are near to developing a commercially acceptable substitute.
Existing Sources ofAsbestos Exposure
Phased Approach ofAnalysis ^
The widespread use of asbestos makes evaluating substitutes, assessing economic impact and examining other factors necessary to support regulation a difficult and time consuming process. Therefore, the Agency is conducting regulatory assessments in a systematic manner on all asbestos product categories.
The following product categories account for the major portion of asbestos used in 1978: Paper products
Although risk associated with newly processed asbestos may be substantial, the continuing aggregate risk associated with existing and past asbestos use may be equally and possibly more significant Unfortunately, reducing risks from the latter group is more complicated than reducing new risks because of difficulties In identifying all the related exposure sources, the lack of feasible control options for many sources, and the large costs associated with removing and replacing existing

products. Some existing asbestos products, however, are amenable to evaluation and control. For example, asbestos has been widely used for insulation in schools and other buildings. In some of these buildings the insulation has deteriorated and fibers are entering the air in the buildings. EPA is currently investigating whether to require surveys of public schools for `
asbestos and appropriate control actions wherever exposure problems are identified. This action was announced in another ANPRM published in the Federal Register on September 2ft1979 (44 FR 54676).
Other existing uses of asbesto^ will be examined where practicable dunng subsequent stages of the asbestos regulatory investigation. Possible candidates include all public buildings and merchant ships.
Information Gathering under Section 8(a) of TSCA
EPA is developing a section 8(a) rule to help gather information needed for this investigation. The information will be used to determine appropriate regulatory action under TSCA as well as under other laws administered by EPA and other Federal activities. EPA invites comments on the need for such a rule; who should be subject to. or exempt from reporting: what information should be gathered under this authoritjcand how the section 8(a) rule should be designed.
Under section 8(a), EPA could require maintenance of records and reporting by persons who mine or mill asbestos, process asbestos (including making asbestos-containing products), and import asbestos or asbestos-containing products. Insofar as the information is known to, or reasonably ascertainable by those persons, the Agency could require reporting of information about any aspect of asbestos manufacture and processing. Possible reporting topics include the composition of asbestoscontaining products, the uses of each product, all existing data concerning environmental and health effects, the number of individuals exposed in workplaces, and the duration and extent of these exposures, and the manner and method of asbestos waste or product disposal.
The section 8(a) rule could be designed in several ways depending, in part on the control strategy selected by the Agency. A single rule might require
one-time reporting of information, while a series of rules might require phased reporting by industry segments. Either type of rule could establish different reporting requirements for the various groups or persons (i.e., millers.
processors, importers of asbestos) subject to (he rule_A-rula might require immediate submission.of some information while retaining the authority to request other specified information by letter at a later date, the possible scope of a section 8{a) rule is discussed in more detail in the issue section below.
Citizens Petition
Under section 21 ofTSCA. a citizen may petition EPA to initiate a ' proceeding for the issuance, amendment, or repeal ofa rule under various provisions of the Act On June 21.1979, the Agency received such a petition requesting that a proceeding be initiated to restrict future use of asbestos-cement pipe in drinking water supply systems. This request is compatible with the. Agency's plans, as announced in this Notice, to initiate a comprehensive investigation of commercial and industrial asbestos uses including asbestos-cement pipe.
The Administrator's response to the petition notes that the evaluation of health effects information on risks resulting from the ingestion of asbestos is not yet complete. It also states that the Agency has just begun gathering exposure and socioeconomic information on asbestos-cement products. Thus, it is not EPA's intent to include asbestos-cement pipe as a candidate for initial rulemaking. Nonetheless, because the Agency has initiated investigations to support a decision on whether to regulate asbestos-cement pipe under TSCA. the Administrator granted the petition.
Issues
Several issues must be resolved during this asbestos rulemaking process. EPA invites comments on the following issues and any others which might be relevant
1. Health Effects ofSubstitutes. To adequately assess substitutes for asbestos. EPA requests health, environmental and socioeconomic information on substitute materials. This information has two purposes; (1) it will allow an informed analysis of the health effects of the substitutes for comparison with the known hazards of asbestos, and (2) it will enable a balanced consideration of the environmental, economic, and social impact of any action taken by the Agency.
We are particularly concerned with materials, such as fibrous glass, that might have physical dimensions and characteristics very similar to those of asbestos fibers, but differ only in chemical composition. EPA is. aware of relevant research, especially the studies
by Stanton fc,t*PoU * ,#aud ..
others.*1 `v** *,4 '* These studies '.... . suggest that the length and widthToT fibers or the ratio of the width to the length may be more important tfcm.tinir chemical imposition in determining. carcinogenicity.More specifically^ current research, findings sufflest thst fibers with diameters less thanor equal to 14 microns and'lengths between 5 and 60 microns are likely to have greater fibrotic and carcinogenic potency than fibers fallingoutslde these ranges
Consequently, we plan to adopt & policy that nonasbeStos fibers with physical . dimensions within these ranges are nof
appropriate.substitutes unless
appropriate testing indicates otherwise. .Fibrous orother substitutes which do not present major health risks would be determined to be suitable. EPA solicits comments on this approach.

Insofar as these nonregulatory avenues (e.g., this ANPRM, contractor studies, and other informal information requests) do not provide, or are not.
likely to provide sufficient information, the Agency will promulgate a section 8(a) rule. The issue at hand regards the appropriate scope of the section 8(a) rule. The Agency would like to minimize reporting burdens on industry. To this end. the promulgation of.such a rule and its potential content will be influenced by responses to this ANPRM and informal Agency requests and by the need for confidential business information or other data not likely to be provided on a voluntary basis.

The Agency may also develop.regulations for asbestos waste 1 management under Subtitle C of the Resource Conservation and Recovery Act 42 U&C. 6921 to 6931.
Under section 9 of TSCA. 15 U.S.C. 2608. the Administratin' will consider, whether risks from asbestos exposure could be reduced to a sufficient extent by actions taken by other agencies under other Federal laws. The ' Administrator will also consider whether rules promulgated under Other EPA authorities could address the asbestos problems more effectively. To maximize the effectiveness of this proposed rule, EPA is coordinating with several agencies both directly and through the Interagency Regulatory Liaison Group (IRLG). These agencies include the Food and Drug Administration, Consumer Product Safety Commission, Department of Agriculture, Mine Safety and Health Administration, and Occupational Safety and Health Administration.

interested groups to obtain their views on regulatory needs, the Agency's approach, and technical issues. Information exchange will be facilitated through various public participation
mechanisms, including public meetings and public hearings'at appropriate ' locations around the country.
A financial compensation program for public participation will be available to applicants meeting eligibility criteria. The funds may be used for the cost incurred in commenting op proposed rules after publication. A Notice of
Questions and Information Needs
To assist the Agency in gathering information for regulatory decision making, EPA invites comments on, and responses to, the questions and information requests that are listedhera or are discussed elsewhere in this Notice.*
1. The Agency solicits suggestions relating to the definition of several key terms identified below as well as other terms members of the public consider important to regulatory decision-making.
* CSPC. in on Advance Notice of Proposed Rulemaking appearing elsewhere in Ibis issue of the Federal Register, announces a program to
" These standards included certain work prac tice requirements which the United States Supreme Court in Adorno v. Train. 98 St CL 566 (1978), found to be invalid. The Clean Air Act was amend ed by Congress In 1977 and 1979 to provide EPA with (he authority to prescribe and enforce work practice standards. These asbestos standards are being promulgated again by EPA.
Availability of Grant Funds will be
published in the Federal Register announcing the financial compensation program, eligibility criteria, level of funding, and the procedures for applying for reimbursement.
investigate (he use of asbestos in consumer products. As part of this investigation. CPSC n-il! solicit information through u variety of voluntary and regulatory means. To reduce potential reporting burdens on industry, CPSC will take into account response to EPA's questions when tailoring thr Commission's requests for information on the use hi asbestos in consumer products.

To the extent possible the Agency
would like our definitions toconform to generally accepted usage. Thetenns to
be defined include: (1) asbestos.^) ; encapsulated fibers, (3) locksd-fibers, (4) easily released fibers,, and (5) friable .
materials. 2. The Agency is requesting all
unpublished data or estimates relating to human exposure and to' human health
risks from exposure to.asbestos during mining, manufacturing, processing, use,
and disposal for all asbestos products including the following product categories:
(a) Asbestos paper, including roofing and floor underiayments;
(b) Friction products: (c) Asbestos cement sheet; (d) Asbestos cement pipe; (e) Textiles; (f) Flooring; (g) Gaskets and packings; (h) Paints, coatings and sealants; (i) Asbestos-reinforced plastics. The information submittals should include data on exposure of both
workers and people near mining, manufacturing and processing facilities. Where data might be extensive, covering several years, many work stations or many sampling points,
summaries which include appropriate statistical analysis would be sufficient
Data of interest include present and future estimates of:
(a) The number of people exposed; (b) The routes, duration and frequency of exposure; (c) The intensity of exposure (fiber concentration preferred); (d) Fiber size distributions; (e) Fiber types; (f) Relative and attributable risk estimates for all cancers of specific
organs and nonneoplastic respiratory diseases;
(gfVariations in risk by age, sex, smoking status, duration and intensity of exposure, fiber types, and time from onset of exposure; and
(h) Technical controls currently used to monitor and control exposures to asbestos at the plant site.
3. Based on preliminary information, a list of asbestos-containing commercial and industrial product categories is presented in the Appendix to this Notice. The extent of human exposure to asbestos fibers from these products depends on many factors including the releasability of the fibers, the duration of the exposures, and the size of the population exposed throughout various -
parts of the life cycle of asbestos fn the' product. Products which release
asbestos fibers during normal use, installation, maintenance, removal, or plausible mishandling are of particular concern during the use segment of the
life cycle. Categories containing
products which EPA believes may fall
into this classification are noted with an asterisk in die Appendix. Identification
of these products was based not upon
testing but upon generally available information. The Agency is interested in
determining the necessity ofusing asbestos in these products. The Agency
requests the following information on
these products and other asbestos-
containing products.. (a) Do these products contain
asbestos? (b) What is the purpose of asbestos in
the product; what is me asbestos
content by percentof total composition: and weight; and what is the asbestos -
fiber type, size and shape? (c) What are the figures for annual
production and sales of the product, and
the annual amounts of asbestos used in
each product? (d) What is the value of the product
and the cost of'the asbestos usedin that
product?
;
- (e) What exposures are expected
during the manufacture of the asbestos-
containing product; and what are the expected exposures associated with ..
each use? (Rate of fiber release,
frequency, duration, population
exposed, and conditions of use.)
(f) What point source and non-point,
source discharges of asbestos to water
are associated with the processing of
asbestos fibers, manufacture and use of
asbestos-containing products (e.g..
quantity, concentration)?
(g) What amounts and types of
asbestos-containing wastes are .
generated in connecton with
manufacture of the product; and what
methods and sites of storage, treatment
and disposal are currently used, for
those wastes?
(h) What are the product life, and
expected removal and disposal
techniques for each use? What type of
disposal sites are used? '
4. The Agency is requesting the
following information regarding the
industry structure.
(a) What are the current trends in the.
use of asbestos andasbestos-containing
products?
(b) Is the market stable? .
*> -
(c) What size and type of industryis
most likely to be affected by regulation
of asbestos under TSCA7
-
(d) What effects on industry structure
would be anticipated from regulation / -
under TSCA?
(e) What effects on employment can '

be measure'd at 10* fibers/m*, 10* fibers/ m*. 10'fibers/m*, or 10* fibers/m*, and can waterborne fiber levels bemeasured at 10* fibers/liter. 10' fibers/liter. 10* fibers/liter, 10s fibers/liter or 10* fibers/ liter? Should the level be expressed as total fibers or as fibers greater than a specified length or aspect ratio? Are other parametersmore appropriate (e.g., total mass release, etc.)?
B. What unpublished data are available regarding ambient levels or asbestos in air and water and asbestos exposure from various noncommercial asbestos sources such as drinking water supplies and naturally occurring asbestiform rock?
10. EPA and CPSC intend to share information received in support of their respective asbestos regulatory '. investigations. However, in view of potential statutory conflict regarding treatment of confidential business information, how should the agencies treat data for which a company claims confidentiality?
