Occupational Exposure to Asbestos
AGENCY: Occupation Safety and Health Administration (OSHA). Labor.
action: Emergency temporary standard.
SUMMARY: OSHA is issuing an emergency temporary standard (ETS) to reduce the permissible exposure limit (PEL) for asbestos from 2 fibers (longer than 5 micrometers) per cubic centimeter (2 f/cc) as an eight-hour timeweighted average, lo 0.5 f/cc. During the period of the emergency standard, employers may use all practicable control methods, such as engineering controls, work practices and personal protective equipment to meet the new limit of 0.5 fibers per cubic centimeter (0.5 f/cc). Training programs ere also required to be instituted within 30 days.
The basis for this ETS is OSHA's determination that continued employee exposure to asbestos under current conditions that exceed 0.5 f/cc presents a grave danger of developing asbestosinduced cancer and asbeslosis to exposed employees, and that an emergency standard is necessary to protect them. The ETS serves also as a proposal to revise the current asbestos standard pursuant to section 6(b] and 6(c) of the Act.
This notice also requests comments on the appropriateness of including the provisions of the ETS as permanent revisions to the asbestos standard. In addition, OSHA will soon publish a separate notice of proposed rulemaking that further explains the issues under consideration for the permanent standard and which raises Borne additional issues regarding the application of certain provisions of the asbestos standard to the construction industry. That notice will invite public comments and will schedule a rulemaking hearing pursuant to Section 6(b) of the Act concerning the proposed permanent revision lo the asbestos standard. dates: The effective dale for this ETS is November 4,1983. Comments and evidence concerning the proposed revisions to the permanent standard made by the ETS must be received on or before January 3.1984. As noted, OSHA will publish a notice of proposed rulemaking shortly that will set due dates for submissions to the asbestos docket for the issues raised (herein.

The ETS requires that employees may not be exposed to concentrations or asbestos exceeding 0.5 f/cc on an 8-hour
1. Introduction
This is an emergency temporary standard (ETS) issued pursuant to
time-weighed average basis, and permits the employer to choose among engineering controls, work practices and respirators to reduce exposures lo the
section 6(c) of the Occupational Safely and Health Act of 1970 (the Act) (84 Stat. 1596; 29 U.S.C. 655). the Construction Safety Act (Pub. L. 91-54; 40 U.S.C 333), the Longshoremen's and Harbor Workers Compensation Act (33 U.S.C. 941), the Secretary of Labor's Order No. 9-63 (48 FR 35736). and 29 CFR Part 1911. This emergency standard consists of revisions to the existing standard covering occupational exposure to asbestos, 29 CFR 1910.1001,
new PEL. However, the requirement in 1910.1001(c) to utilize feasible engineering controls and work practices to reduce exposure levels to 2 f/cc remains in effect under this temporary standard. The ETS also requires employers to institute a training program within thirty days of the effective date of this emergency standard. The training progam will include instruction on respirator filling and use, handling of asbestos, medical information, tbe
in order lo protecl employees from a grave danger from continued exposure to asbestos at current exposure levels.
OSHA has deteimined that workers exposed to asbestos under exposure conditions existing under the current standard face a grave danger of

developing incurable cancer and asbeslosis. Further, OSHA has found that an immediate reduction in exposure levels to 0.5 f/cc or below is necessary to prolecl such employees from this
grave danger. Therefore OSHA is issuing this ETS to compel reduced exposures to respond to this emergency situation.
OSHA's determination that a grave danger currently exists is predicated upon quantitative risk estimates in this record which point to a large number of excess deaths from cancer (and

However, the Agency believes it is appropriate to calculate benefits deriving from an ETS using lifetime risks from 20 end 45 years of exposure to tbe PEL of 0.$ f/cc established by the ETS. Although the ETS expires within 6 months. Section 6(c) require* that rulemaking on a permanent standard also be completed within ft months, so that there

As provided in 29 CFR 1953.22, the 24 Stales with their own OSHA-approved occupational safety and health plans are
expected to adopt a comparable slumlord within 30 days of this publication date. These States are: Alaska, Arizona, California,'Connecticut (for State and local government employees only). Hawaii, Indiana, Iowa, Kentucky. Maryland. Michigan. Minnesota, Nevada, New Mexico, Norlh Carolina. Oregon, Puerto Rico. South Carolina. Tennessee. Utah. Vermont, Virginia, Virgin Islands. Washington, and Wyoming.
Also, in response to the emeigcncy conditions faced by exposed workers, OSHA is stepping up its enforcement activitie.s in targeting workplaces where asbestos is handled.
The temporary provisions that are being added to the existing asbestos standard prescribes the major components of an occupational safety and health standard. In general, most of the current requirements remain unaffected by the emergency temporary standard. However, compliance with some requirements will be triggered by the new exposure limit of 0.5 f/cc instead of the former PEI. of 2 f/cc. For example, requiiements such as chunge rooms remain unaffected by the ETS and the trigger level for change rooms remains the former PEL of 2 f/cc
(5 19UU001|d)|4)). However, the ETS requires that where concentrations may exceed the new PEL, the employer must post signs indicating such locations ( 1910.1001|k)(6)].
OSHA based its decisions concerning appropriate provisions for the ETS on its determinations of the kind and degree of protective action needed to protect against a grave danger and the feasibility of instituting these provisions during the period of the El'S.
Under section 6(b| of the Act. OSHA will shortly schedule an informal rulemaking hearing on the proposed permanent changes to the standard. OSHA will also propose other revisions to the asbestos standard that will be explained in the separate notice of proposed rulemaking. Application of certain provisions of Ihc asbestos standard to the construction industry will be raised al that lime. OSHA anlicipstes that this notice will be published shortly. OSHA is now accepting written comments on those issues raised in the ETS which are relevant to revising the permanent rule. The Secretary must promulgate a section 6(b) standard no later than six months after publication of the emergency standard.
II. Legal Authority and Background
A. Legal Authority
Section 6(c) of the Act provides for immediately effective emergency temporary standards in certain circumstances. The Secretary has the authority to issue such a standard, without rulemaking, "if he determines (A) that employees are exposed to grave danger from exposure to substances or agents determined to be toxic or physics fly harmful or from new hazards, and (B) that such emergency standard is necessary to protect employees from such danger." 29 U.S.C. 655(c)(1). Thus, the danger must be `'from" worker exposure .and it must be "grave," not merely significant and the. regulation must be "necessary" to address "such danger," not merely reasonably necessary or appropriate to provide safe employment. In addition. a6 in section 6(b) permanent standards, OSHA may impose requirements in the emergency standard only to the extent that they are "feasible" within the meaning of section
6(b)(5) of the Act. The Fifth Circuit has emphasized the
importance of the severity of health effects in OSHA's consideration of whether an ETS is appropriate:
..........the danger of incurable, permanent,
or fatal consequences To workers, as opposed
to easily curable and fleeting effects on their
health, becomes important in the '
consideration of the necessity for emergency
measures to meet a grave danger." Florida
Pooch Growers Association, Inc. v. United
Stales Deportment of Labor, 4898 F.Zd, 13Z
(CAS).
'
OSHA also has interpreted relevant judicial decisions to require that its evaluation of the gravity of the danger and the necessity for emergency action must be made in the context of actual workplace conditions.
B. Background
1. Events Leading to the ETS. In June, 1983, OSHA received a petition for an ETS from the international Association of Machinists and Aerospace Workers (Exs. 84-244). Subsequently letters supporting this petition were received from 16 other unions (Ex. 84-284 to 84 294, 84-367 to 84-391). The petition requested an ETS to reduce the PEL to 0.1 f/cc. to modify some existing work practice requirements, and to require other protective provisions regardless of exposure level. The main reasons set forth in the petition and supporting . letters are that continued exposure under current workplace conditions constitutes a grave danger and that delaying remedial action until a
permBnent standard is promulgated would cost large numbers of currently-
exposed workers iheir lives. OSHA
shares Ihc genuine concern expressed by the petition and letters from unions representing thousands of employees who are directly faced with the threat < asbestos-related disease from continue exposure. And OSHA concludes that failure to issue this ETS may cost a number of exposed workers their lives.
In August 1983, OSHA completed a comprehensive risk assessment based on numerous human studies which estimated the number of excess dealhs from the three major asbestos-related cancers, i.e., lung cancer, mesolbeliom; and gastrointestinal cancer. 8t the current permissible exposure level of 2 f/cc and el various reduced exposure levels. OSHA placed this document, "Quantitative Risk Assessment for Asbestos-Related Cancers", in the Asbestos docket in August 1983 (Ex. 84 349). OSHA subsequently revised this document (Sec Ex. 84-392).
2. History of the Asbestos Standard OSHA bus regulated asbestos since 1971. A12 f/cc limit for asbestos was included in the initial promulgation of OSHA standards pursuant to section 6(a) of thfrAct, on May 29,1971 (36 FR 10466). In response to a petition by the Industrial Union Department of the AFL-CIO, OSHA issued an ETS on asbestos on December 7,1971, which established a PEL of 5 f/cc on a timeweighted average basis and peak exposures of 10 f/cc.
The current standard, promulgated in June 1972, first established an 8-hour time-weighted average PEL of 5 f/cc am a ceiling limit of 10 f/cc. The limits wen intended primarily to protect employees agBinst asbeslosis, and it was hoped that they would provide some incidents degree of protection against cancer. Effective July 1976, the TWA limit was reduced by,the standard to 2 f/cc. This limit has remained in effect since that
time. The standard also includes provisions covering methods of compliance, monitoring, medical
surveillance and housekeeping. Court review of this standard upheld
all major provisions, but remanded two issues for OSHA's reconsideration, HJD v. Hodgson, 499 F. 2d 467 (CADC1974). These issues were whether the July 197f date for the 2 f/cc standard should b'e accelerated for some industries and the adequacy of the 3 year retention period for exposure monitoring records. Subsequently, OSHA increased this retention period to 20 years (41 FR 11504) and the acceleration issue became moot.
After reviewing the then available scientific data, in October 1975 OSHA published a notice of proposed

VI. Technical and Economic Feasibility
Based on an evaluation of evidence contained in the record, OSHA finds that the provisions required by the ETS are technically and economically feasible. OSHA has examined the various industries and work operations impacted by the standard and their ability to comply with the provisions of the ETS. Because the ETS requires prompt reduction of risk, OSHA

assessed the industry's ability to implement the required controls immediately.
The ETS allows considerable flexibility in achieving the PEL. As n result, three options are available to
lower the asbestos filter concentrations to which workers are exposed: (1) Engineering controls such as automatic bag opening devices, specialized
vacuum equipment and increased ventilation: (2) work practices, such as wet treatment of the asbestos material and increased clean-up of the work
place, and (3) use of approved respirators. Due to the emergency nature of this action which requires immediate response to reduce worker exposure, OSHA assumes that respirators will he the initial method used to comply with the ETS. A full discussion of the technological and economic feasibility
of the alternative methods for each industry and For the various PEi.s under consideration for revising the permanent standard will accompany the proposal which will be published separately.
OSHA believes that, consistent with the estimates of current exposure levels, engineering controls are currently in place and work practices, in operation which, if applied conscientiously, would immediately result in concentrations at
least as low as 0.5 in many industries (Ex. 04-262; Ex. 84-263: Ex. 84-9 and Ex. 84-295). For purposes of assessing the technological and economic feasibility,
however, OSHA assumed a worst-case scenario in which each industry segment would have to implement a respirator program in order to achieve immediate reduction in worker exposure levels below the estimated current
uonccntialiens. Furthermore, lor purposes o' worst-case analysis, OSHA assumed lhat none of these industries
has any respirator program except for the shipbuilding and construclion segments. OSHA makes this assumption because OSHA estimates that most workers in industries other than shipbuilding and construction are exposed to eight-hour time-weighted averages less than Z ffec. end the OSHA standard issued in 1972 only requires a respirator program when engineering controls and work practices cannot bring exposures to 2 f/cc. To the extent that some firms do have an existing respirator programt the costs are overestimated.
A. Technical Feasibility
The following table presents the assumptions OSHA made regarding the respirator program felements required by each industry io obtain a PEL of 0.5 f/cc. The types of respirators needed for each industry sector were determined using the respiraior selection table in the ETS with reference to the estimated current exposure conditions. OSHA assumed that the least costly approved respirator would be selected. For example, where industries have exposures less than ten times the PEL. OSHA anticipated that disposable respirators would be purchased, because of their lower short term costs. When exposures exceeded ten times the PEL, OSHA assumed that some plants would either use air line respirators, or full facepiece respirators, depending upon the operation. To the -extent that firms choose a higher-cost respirator to increase the protection factor or durability, respirator costs may
be understated. Furthermore. OSHA has not included in the cost analysis a consideration for lost worker productivity due to wearing respirators. Costs may be understand by whatever amount productivity is reduced. Other anticipated respirator program elements required to determine costs for the ETS are listed below. These elements are derived from the existing provisions found in the Asbestos Standard. 29 CFR 1910.1001 and the standards for respirators, 29 CFR 1910.134.
All of the required respirators and filters arc readily available and can be
purchased through local distributors. Since the program relies mostly on disposable respirators. OSHA considers that there will be no supply constraints. As the worst-case (or high) estimate, OSHA assumes that approximately 50,000 workers will wear respirators because of the ETS who did not previously wear respirators. OSHA has concluded that the use d( respirators will be effective in providing improved
worker protection during the period of the ETS. In addition to encouraging generally more widespread use of respiratory protective measures, the ETS will stimulate a heightened understanding of the health hazards from asbestos exposure and will result in more effective use programs and strategies. Issues involving the appropriateness of respirator usd as a long-term solution to controlling -
asbestos exposures are raised in the section 8(b) rulemaking proceeding (see Ex. 84-345, 84-346. 84-347, 84-348).

^OSHA assumes that certain jobs such as cleaning of vacuum equipment will produce
exposure levels greater than 10 times the PEL. Consequently, OSMA assumes 2 air line respirators will be required per plant except for small operations which will require only one air-line respirator per plant. "Administrative costs represent the salary of one full time professional at $30,000
per annum and one full time clerk at $15,000 per annum. OSHA has adjusted administrative costs to represent expected reasonable time spent administering a respirator program in each industry. In the secondary fabrication and automotive
aftermarket sectors, for example, OSHA anticipates that supervisors will spend 15 minutes a day distributing and monito, ing the use of disposable respirators. Ihese sectors have far Jess of a management burden than large firms, and thus,
administrative costs are calculated at i percent of the fuii administrative amount. OSHA believes that administrative costs have been overstated in most segments in order
to present a worst case scenerio.
c0SHA assumes that every employee must be fit tested for respirator use at a cost of $21 per employee. "uSHA has allowed 3 hours for respirator and asbestos training. OSHA considers that
this is very liberal, especially in industry segments characterizeo by small plants and by the use of disposable respirators. Costs for this element are therefore overstateo to present the worst-case scenario.

Costs for warning signs are not included, since, for the purposes of the ETS, these signs could be hand-made at very low costs. OSHA did nol analyze costs associated with the alternate benefits scenario (See Table 4) since that scenario was constructed to show a lower range of benefits hot does not represent an estimate of current industry
practice.
The costs are overstated to the extent that some firms already have a current respirator program and to the extent that careful application of existing engineering controls and work practices would reduce concentration* to the PEL in some firms and thereby make respirator use unnecessary. Furthermore, the costs assume that dust masks and filters will have to be replaced every 8-hour day. Some of this cost (i.e.. the disposable respirators, filters and administrative overhead) can be in fact spread over the period during which the ETS is in effect.
Finally, the costs assigned to the
Shipbuilding/Repair and Conslruction-
Dcmnlition/Renovation segments
represent cost which reflect increased
compliance with current obligations (e.g.
increased respirator use to meet the '
current standard as a result of the ETS
training requirements) and are not,
.
directly attributable lo the ETS.
Note.--OSHA anticipates that the T"S will
spur many employe* who previously were
not in compliance to expend the necessary
resources in order to come into compliance
with the El'S.

The total cost is estimated at
$35,565,402 for 6 months. This translates
into an average cost par employee of
$708. Average 6 month costs per worker
presented on an industry basis in Table
17 range from $251 in the automotive
aftermarket segment to $973 in the
construction segment. These costs are
not a large portion of industry shipments
as presented in Table 18. Moreover,
firms in these industries will be able to
pass the costs forward because asbestos
substitutes in most industries are not
immediately available. For all these
reasons, OSHA finds that the ETS is
economically feasible.

VII. Environmental Impact, Requirements of Executive Order 12291, and the Regulatory Flexibility Act
The National Environmental Policy Act (NF.PA) of 1969 (U.S.C. 4321 et seq.), as implemented by the guidelines {40 CFR Part 1500) of the Council on Environmental Quality (CEQ). requires that federal agencies assess their regulatory actions to determine if there is a potential for a significant impact on the quality of the human environment and. if necessary, to prepare an environmental impact statement.
In accordance with these requirements and DOl. NEPA regulations (29 CFR Port 11 fSubpart B, 11.30 (a) (4)1) OSHA had determined that because of the emergency nature of this standard, no environmental impact statement will be perpared for the ETS. The courts have held that NEPA does not require advance preparation of an environmental impact statement for an OSHA ETS {Dry Color Manufacturing Assocation v. U S. Department of Labor
486 F.2d 96.107 (3rd Cir. 1973)), OSHA will assess, however, the environmental effects of the proposed permanent regulation of asbestos. The results of this study will be available for review and comment prior to the hearings on the proposed permanent standard and wilt be an appropriate issue for discussion at the public hearing.
In the interim. OSHA welcomes any comments on any environmental effects (hat might occur as a result of promulgation of h rule on ashetos.
Pursuant to the authority of Section 6(a)(1) of Executive Order 12291 OSHA has not prepared a Regulatory Impact Analysis of this ETS. Preparation of such an analysis was not practicable for OSHA to perform in time to issue this ETS to respond to the grave dangers faced by asbestos exposed workers. OSHA. however, is completing a Preliminary Regulatory Impact Analysis of the proposal to revise the permanent
standard which will be made public al lire lime the proposal is published.
The Regulatory Flexibility Act requires an agency to prepare a
Regulatory Flexibility Analysis only for those rules for which a notice of proposed rulemaking is published. OSHA's issuance of an ETS therefore is not covered by the Regulatory Flexibility Act because the OSHA Act provides that ETS's be issued without regard to notice, public comment and other requirements in the. Administrative Procedure Act. The proposal to revise the permanent asbestos standard, however is subject to the requirements of the Regulatory Flexibility Act and OSHA will evaluate
the proposal lo ascertain whether analysis under the Regulatory Flexibility Act is required.
VIII. Summary Bnd Explanation of the ETS
The requirements of this-emergency temporary standard are set out in a gew paragraph, $ 1910.1001(k). They are limited to additional provisions to the existing asbestos standard which OSHA considers essential and feasible to protect employees from fhe grave danger resulting from asbestos exposure until OSHA can promulgate more comprehensive revisions in accordance with section 6(b) of the <^ct. The major changes in the standard made by the FI'S are: (1) The new permissible exposure level; (2) methods of compliance permilted to achieve the new ievel; and (3) a requirement for the est ablishment. of training programs within 30 days. The following section discusses the major provisions of the ETS. the necessity for including these provisions in the ETS, and some additional provisions lo trigger certain requirements at the reduced permissible level of 0.5 f/cc.
1. Paragraph (k)(tj Scope. As part of the ETS, OSHA is adding a paragraph on the scope of the standard. The paragraph is intended lo make dear that the emergency standard applies lo all workplaces where employees may be exposed to asbestos in all industries covered by the current asbestos standard ic. general industry, construction and maritime.
2. Paragraph (k)(2j Permissible level of exposure. As part of the ETS. OSHA is adding paragraph (k)(2) which sets a new PEL, effective immediately, of 0.5 f/ cc on an 8 hour time weighted average basis. This reduced level may be achieved by any feasible combination of engineering controls, work practices and respiratory protection in order to allow employers to institute effective measures !o reduce employee exposures immediately.
OSHA chose 0.5 f/cc as the permissible exposure level primarily because it believes that reducing employee exposures to 0.5 f/cc in all industries will greatly reduce the risk of developing asbestos induced cancers, primarily lung cancer, mesothelioma and gastrointestinal cancer. As set out In the discussion on "grave danger" and "benefits", the number of lives OSHA believes may be saved through an immediate reduction of exposure to 0.5 f/cc is substantial.
OSHA also believes that the 0.5 f/cc level is appropriate for several other reasons. First, because an emergency standard must be feasible, and
employers must be able to comply with
the standard in a short period ol time. OS! 1A has set a level which (S likely to be achieved immediately, using equipment and control techniques that are currently available.
Second. OSHA believes, based on the d8la generated by OSHA's contractor. Research Triangle Institute, that some workplaces, especially in the manufacturing sector, may be close lo achieving a 0.5 f/cc level through the more rigorous use of engineering controls, work practices and housekeeping methods which are now in place. OSHA encourages employers lo continue their efforts to implement these methods in order to assure that, for the long term, the most comprehensive and effective program of protection from asbestos exposure will be provided.
Third, OSHA believes that reliability of the currently required asbestos measurement methods (o measure asbestos exposures less than 0.5 f/cc should be open for discussion during a rulemaking hearing, rather than imposed through an ETS. OSHA has therefore not adopted the 0.1 f/cc level petitioned by the unions but instead i9 considering adding provisions to the asbestos
standard that may improve the reliability of both sampling and analysis in the 6(b) rulemaking for the permanent standard and thus allow lower levels to
be reliably measured. 3. Paragraph (k)(3) Methods of
compliance. The ETS adds a new paragraph (k)|3). which permits employers to reduce the permissible exposure limit from the current 2 f/cc limit lo the 0.5 f/cc limit by any feasible combination of engineering controls, work practices and respiratory protection. The current requirement in paragraphs (c)(1) and (c)(2) to first utilize engineering controls and work practices to reduce exposure levels to 2.0 f/cc remains unaffected by this ETS.
Flexibility in choosing compliance strategies for the period of an ETS has been incorporated in most other
previously issued emergency standards. The policy reflects OSHA's determination to craft emergency standards that are truly responsive to emergency conditions and which afford immediately available protection to affected workers.
4. Paragraph fk){4) Employee information and training. The ETS adds a paragraph to the asbestos standard requiring the employer to provide a training program within 30 days of publication of (he emergency standard for all employees whose exposures are reasonably expected to exceed the PEL of 0.5 f/cc. without regard to the use of
