    SUMMARY: OSHA is amending its standard regulating occupational exposure 
    to methylene chloride (29 CFR 1910.1052) by adding a provision for 
    temporary medical removal protection benefits for employees who are 
    removed or transferred to another job because of a medical 
    determination that exposure to methylene chloride may aggravate or 
    contribute to the employee's existing skin, heart, liver, or 
    neurological disease. OSHA is also amending the startup dates by which 
    employers in certain identified application groups, i.e., who use MC in 
    certain work operations, must achieve the 8-hour time-weighted-average 
    permissible exposure limit and the dates by which they must achieve the 
    short-term exposure limit by means of engineering controls.
        On May 4, 1998, OSHA published for comment amendments to the 
    standard along the lines requested in a motion for reconsideration 
    filed by the International Union, United Automobile, Aerospace and 
    Agricultural Implement Workers of America (UAW), the Halogenated 
    Solvents Industry Alliance, Inc., and others. OSHA reopened the 
    rulemaking record for 30 days for the limited purpose of receiving 
    public comment on the amendments (63 FR 24501, May 4, 1998). Based on 
    the rulemaking record and the comments received, OSHA is now adopting 
    the amendments as published, with one minor modification.
    
    DATES: This final rule becomes effective on October 22, 1998, except 
    that the revision of paragraph (n)(2) of Sec. 1910.1052 (regarding 
    start-up dates) becomes effective September 22, 1998. See SUPPLEMENTARY 
    INFORMATION for a table of start-up dates established in this final 
    rule.

    OMB Review Under the Paperwork Reduction Act
    
        OSHA submitted an amended Methylene Chloride Information Collection 
    Request (ICR) to the existing Methylene Chloride ICR (OMB Control 
    Number 1218-0179) when the proposal for Methylene Chloride: Notice of 
    Motion of Reconsideration was published. This amendment calculated 
    burden hours and costs for the additional medical examinations 
    resulting from the inclusion of the Medical Removal Protection 
    provisions. On July 2, 1998, OMB approved the amendment. All methylene 
    chloride collections of information expire on 7/31/2001.
        This final rule also extends the compliance dates for the 
    implementation of engineering controls and respiratory protection for 
    employees engaged in selected activities. Paragraphs (n)(2)(A), (B), 
    and (C) provide new implementation dates for engineering controls for 
    employers engaged in the following: polyurethane foam manufacturing; 
    foam fabrication; furniture refinishing; general aviation aircraft 
    stripping; product formulation; adhesive users using adhesives for boat 
    building and repair, recreational vehicle manufacture, van conversion, 
    and upholstering; and construction work. Those employers who choose the 
    option of postponing the implementation of engineering controls and 
    respiratory protection are required to conduct quarterly short-term 
    exposure limit (STEL) monitoring until implementation of the 
    engineering controls and respiratory protection. Since this requirement 
    is already present in the final MC standard, the Agency will submit an 
    ICR to OMB to increase those
    
    [[Page 50713]]
    
    burden hours attributed to the additional monitoring. Under 5 CFR 
    1320.5(b), an agency may not conduct or sponsor a collection of 
    information unless: (1) the collection of information displays a 
    currently valid OMB control number; and (2) the agency informs the 
    potential persons who are to respond to the collection of information 
    that such persons are not required to respond to the collection of 
    information unless it displays a currently valid OMB control number.
    
    I. Background
    
        On January 10, 1997, OSHA issued a standard regulating occupational 
    exposure to methylene chloride (MC)(62 FR 1494, January 10, 1997) 
    codified at 29 CFR 1910.1052. The standard was designed to reduce both 
    the risk that worker exposure to MC will cause cancer and the risk that 
    MC will cause or aggravate certain other adverse health effects. The 
    standard reduced the prior 8-hour time-weighted-average permissible 
    exposure limit (8-hour TWA PEL) to MC from 500 parts per million (ppm) 
    to 25 ppm. It also set a short term exposure limit (STEL) of 125 ppm 
    averaged over a 15 minute period.
        The 8-hour TWA PEL was set at 25 ppm to reduce, to the extent 
    feasible, the risk that workers exposed to MC would develop cancer. 
    Data showing that MC exposure presents a risk of cancer included animal 
    bioassay data in multiple species, mechanistic studies detailing the 
    metabolism of MC to carcinogenic products in humans, and 
    epidemiological studies suggesting an elevated risk of biliary cancer 
    and astrocytic brain cancer in MC-exposed workers. The agency used a 
    physiologically-based pharmacokinetic (PBPK) model to estimate the 
    cancer risk. OSHA's final risk assessment estimated that, at the prior 
    8-hour TWA PEL of 500 ppm (a level that the Agency found was 
    considerably higher than the level at which most affected workers were 
    currently exposed, see 62 FR 1565, January 10, 1997), lifetime 
    occupational exposure to MC could result in approximately 125 excess 
    cancer deaths per 1000 exposed workers (62 FR 1563, January 10, 1997, 
    Table VII). At the new 8-hour TWA PEL of 25 ppm, OSHA estimated that 
    the excess cancer risk would be reduced to approximately 3.6 deaths per 
    1000 workers. Id. OSHA concluded that a significant risk to workers 
    remains at an exposure level of 25 ppm but set the 8-hour TWA PEL at 
    that level because it was the lowest level for which OSHA could 
    document feasibility across all the affected application groups (62 FR 
    1575, January 10, 1997).
        The STEL was set at 125 ppm to minimize the adverse health effects 
    caused by acute exposure to MC. Central nervous system (CNS) depression 
    has been observed at MC concentrations as low as 175 ppm. CNS 
    depression is characterized by fatigue, difficulty in maintaining 
    concentration, dizziness, and headaches. These consequences of MC 
    exposure constitute material impairments of health and, by reducing 
    workers' coordination and concentration, can lead to workplace 
    accidents. Also, MC is metabolized to carbon monoxide (CO) and 
    therefore causes health impairment similar to that caused by direct 
    exposure to CO. Carbon monoxide blocks the oxygen binding site on 
    hemoglobin, producing carboxyhemoglobin, or COHb. Elevated COHb levels 
    reduce the supply of oxygen to the heart and can aggravate pre-existing 
    heart disease and lead to heart attacks. Physical exertion increases 
    the concentration of COHb in MC-exposed workers and thus increases the 
    risk of a heart attack, particularly for persons with silent or 
    symptomatic cardiac disease, who may be susceptible to very small 
    increases in COHb due to an already impaired blood supply to the heart.
        The liver and skin are also susceptible to acute effects from MC 
    exposure. Chlorinated hydrocarbons as a class (of which MC is a member) 
    are generally toxic to the liver. However, animal studies indicate that 
    MC is among the least hepatotoxic of this class of compounds. The 
    limited amount of human data that are available is inconclusive but 
    supports the hypothesis that MC is toxic to the liver (62 FR 1515, 
    January 10, 1997). Prolonged skin contact with MC also causes 
    irritation and skin burns (62 FR 1609, January 10, 1997).
        Employers must achieve the 8-hour TWA PEL and the STEL, to the 
    extent feasible, by engineering and work practice controls. If such 
    controls are unable to achieve the exposure limits (and during the time 
    they are being implemented), employers must provide appropriate 
    respirators at no cost to employees and ensure that employees use them. 
    The standard does not permit the use of air-purifying respirators to 
    protect against MC exposure because MC quickly penetrates all currently 
    available organic vapor cartridges, rendering air-purifying respirators 
    ineffective after a relatively brief period of time. Therefore, when 
    respiratory protection is required, the standard provides that 
    atmosphere-supplying respirators must be used.
        The standard requires employers to provide medical surveillance to 
    employees who are exposed to MC either (1) at or above the action level 
    (12.5 ppm) on 30 or more days per year or at or above the 8-hour TWA 
    PEL or STEL on 10 or more days per year; (2) at or above the 8-hour TWA 
    PEL or STEL for any time period where an employee who has been 
    identified by a physician or other licensed health care professional as 
    being at risk from cardiac disease or from some other serious MC-
    related health condition requests inclusion in the medical surveillance 
    program; or (3) during an emergency. The medical surveillance must 
    include a comprehensive medical and work history that emphasizes 
    neurological symptoms, skin conditions, history of hematologic or liver 
    disease, signs or symptoms suggestive of heart disease (angina, 
    coronary artery disease), risk factors for cardiac disease, MC 
    exposures, and work practices and personal protective equipment used 
    during such exposures. The standard's medical surveillance procedures 
    focus on MC's noncarcinogenic health effects because a medical 
    surveillance program cannot detect MC-induced cancer at a preneoplastic 
    stage (62 FR 1589, January 10, 1997). However, the standard's medical 
    surveillance provisions can lead to early detection of cancer and to 
    higher survival rates from early treatment.
        OSHA found that the standard was both technologically and 
    economically feasible in all of the industrial applications that use 
    MC. However, the Agency recognized that larger employers are better 
    able than smaller ones to absorb or pass through the costs associated 
    with compliance with the standard. To avoid placing an undue economic 
    burden on small businesses, OSHA provided for later startup dates for 
    small employers. Larger employers were given until April 10, 1998 (one 
    year after the standard's effective date) to complete installation of 
    engineering controls to achieve the PEL and STEL, while employers with 
    fewer than 20 employees were given a total of three years, or until 
    April 10, 2000, to do so. Employers with fewer than 20 employees were 
    also given more time than larger employers to comply with the other 
    provisions of the standard. In addition, intermediate startup dates 
    were established for polyurethane foam manufacturers with 20-99 
    employees because OSHA anticipated that firms in that group could have 
    somewhat higher capital expenditures to meet the requirements of the 
    standard.
        After the methylene chloride standard was issued, the International 
    Union, United Automobile, Aerospace and Agricultural Implement Workers 
    of
    
    [[Page 50714]]
    
    America (UAW), the Halogenated Solvents Industry Alliance, Inc. (HSIA), 
    and others filed a motion with OSHA asking the Agency to reconsider two 
    aspects of the standard: (1) the agency's decision not to include 
    medical removal protection benefits in the medical surveillance 
    provisions of the standard; and (2) the startup dates for engineering 
    controls and for use of respirators to achieve the 8-hour TWA PEL for 
    employers using MC in certain specific applications. Those applications 
    are:
         Polyurethane foam manufacturing;
         Foam fabrication;
         Furniture refinishing;
         General aviation aircraft stripping;
         Formulation of products containing methylene chloride;
         Boat building and repair;
         Recreational vehicle manufacture;
         Van conversion;
         Upholstery; and
         Use of methylene chloride in construction work for 
    restoration and preservation of buildings, painting and paint removal, 
    cabinet making and/or floor refinishing and resurfacing.
    
    II. Summary and Explanation of the Final Rule
    
        After receiving the motion for reconsideration, OSHA published a 
    notice of the motion in the Federal Register that contained changes to 
    amend the rule substantially as requested in the motion. 63 FR 24501 
    (May 4, 1998). In that notice, OSHA explained why it believed the 
    amendments requested in the motion were justified and were consistent 
    with the rulemaking record. OSHA reopened the record for 30 days to 
    allow the public an opportunity to comment on the amendments. Most of 
    the comments the agency received supported the amendments. Several 
    comments in opposition were received. In this section, OSHA describes 
    the amendments to the MC standard being made by this final rule, 
    explains why it concludes the amendments are appropriate in light of 
    the entire rulemaking record, and discusses the comments received in 
    response to the reopening of the record.
    
    Medical Removal Protection Benefits
    
        In this final rule, OSHA is modifying the medical surveillance 
    provisions in paragraph (j) of the MC standard to provide for limited 
    medical removal protection (MRP) benefits.
        As discussed above, paragraph (j)(1) of the standard requires 
    employers to provide medical surveillance to employees exposed to 
    methylene chloride (1) at or above the action level on 30 or more days 
    per year or at or above the 8-hour TWA PEL or STEL on 10 or more days 
    per year; (2) at or above the 8-hour TWA PEL or STEL for any time 
    period where an employee who has been identified by a physician or 
    other licensed health care professional as being at risk from cardiac 
    disease or from some other serious MC-related health condition requests 
    inclusion in the medical surveillance program; or (3) during an 
    emergency. Such surveillance includes [paragraph (j)(5)] a 
    comprehensive medical and work history that emphasizes neurological 
    symptoms, skin conditions, history of hematologic or liver disease, 
    signs or symptoms suggestive of heart disease (angina, coronary artery 
    disease), risk factors for cardiac disease, MC exposures, and work 
    practices and personal protective equipment used during such exposures. 
    Paragraph (j)(9) requires the employer to ensure that the physician or 
    other licensed health care provider (PLHCP) who conducts the medical 
    examination provides a written opinion regarding the results of that 
    examination.
        Originally, paragraph (j)(9)(i)(A) required that written opinion to 
    include the PLHCP's opinion as to ``whether the employee has any 
    detected medical condition(s) which would place the employee's health 
    at increased risk of material impairment from exposure to MC.'' That 
    paragraph is being amended to provide that the PLHCP's written opinion 
    must include ``whether exposure to MC may contribute to or aggravate 
    the employee's existing cardiac, hepatic, neurological (including 
    stroke) or dermal disease or whether the employee has any other medical 
    condition(s) which would place the employee's health at increased risk 
    of material impairment from exposure to MC.'' If the PLHCP recommends 
    removal because exposure to MC may contribute to or aggravate the 
    employee's existing cardiac, hepatic, neurological (including stroke) 
    or dermal disease, new paragraph (j)(11) requires the employer to 
    either transfer the employee to comparable work where MC exposure is 
    below the action level or remove the employee from MC exposure. In 
    either case, the employer must provide MRP benefits to the employee 
    under paragraph (j)(12) by maintaining, for up to six months, the 
    employee's earnings, seniority, and other employment rights and 
    benefits as though the employee had not been removed from MC exposure 
    or transferred to a comparable job.
        As explained in the notice, MRP benefits are designed to improve 
    employee participation in medical surveillance by removing a potential 
    economic disincentive to such participation. The medical surveillance 
    conducted under the standard can result in a medical opinion that 
    continued MC exposure would endanger the health of a particular worker 
    and a recommendation that the worker should be removed from his or her 
    present job or have his or her work activities otherwise restricted. 
    The possibility of job loss or transfer can lead to concern among 
    workers that participation in medical surveillance could endanger their 
    livelihoods. For this reason, OSHA has generally found that employees 
    will be reluctant voluntarily to cooperate in medical surveillance 
    programs if they believe they could suffer a loss of income as a 
    result. See, e.g., 50 FR 51120, 51154-56 (Dec. 13, 1985) (cotton dust 
    standard); 43 FR 54442-54449 (Nov. 21, 1978) (lead standard). OSHA 
    similarly found, when it issued the MC standard, that MRP benefits 
    would increase employee participation in medical surveillance by 
    removing an economic disincentive to such participation (62 FR 1595, 
    January 10, 1997).
        Although OSHA found that MRP benefits would improve employee 
    participation in medical surveillance, the Agency did not provide for 
    such benefits when it originally issued the MC standard. The Agency 
    noted that there was no biological marker to indicate whether an 
    employee's continued exposure to MC would unduly endanger the 
    employee's health, nor could the Agency identify any other objective 
    criteria that could be used to determine when an employee's exposure to 
    MC should be restricted for medical reasons. Because it did not believe 
    it could offer substantive guidance to medical professionals as to when 
    it would be appropriate to remove an employee from further MC exposure 
    or to return a removed employee to the workplace, OSHA decided not to 
    require employers to provide MRP benefits. 62 FR at 1595.
        The motion for reconsideration suggested that a provision limiting 
    MRP benefits to situations in which a PLHCP recommends removal based on 
    an opinion that continued exposure to MC would contribute to or 
    aggravate an employee's existing cardiac, hepatic, neurological, or 
    dermal disease would provide sufficient guidance to PLHCPs because the 
    specified organs are the ones known or believed to be susceptible to 
    the noncarcinogenic effects of MC exposure. The parties further 
    recommended that OSHA instruct PLHCPs to presume that an employee's 
    medical condition is unlikely to require medical removal if
    
    [[Page 50715]]
    
    the employee is not exposed to MC above the 8-hour TWA PEL. New 
    paragraph (j)(10) includes that presumption and requires employers to 
    remove such an employee only if the PLHCP cites specific medical 
    evidence in support of a removal recommendation.
        OSHA believes that the MRP benefits provision recommended in the 
    motion gives adequate guidance to the PLHCPs who are called upon to 
    make recommendations for or against medical removal under the standard. 
    The provision is consistent with MRP provisions in earlier standards 
    that base medical removal decisions on the informed judgment of the 
    health care professionals who conduct medical surveillance under the 
    standards. For example, the lead standard (29 CFR 1910.1025), in 
    addition to requiring medical removal based on high blood lead levels, 
    requires medical removal ``on each occasion that a final medical 
    determination results in a medical finding, determination, or opinion 
    that the employee has a detected medical condition which places the 
    employee at increased risk of material impairment to health from 
    exposure to lead.'' The cadmium standard (29 CFR 1910.1047) requires 
    medical removal if certain biological triggers are met or if a written 
    medical opinion determines that removal is justified by ``evidence of 
    illness, other signs or symptoms of cadmium-related dysfunction or 
    disease, or any other reason deemed medically sufficient. . . .'' The 
    formaldehyde standard (29 CFR 1910.1048) provides for medical removal 
    if there is a medical finding ``that significant irritation of the 
    mucosa of the eyes or of the upper airways, respiratory sensitization, 
    dermal irritation, or dermal sensitization result from workplace 
    formaldehyde exposure and recommends restrictions or removal.''
        The American Association of Occupational Health Nurses (AAOHN) 
    suggested that the criteria for medical removal are insufficiently 
    specific and will be difficult for health care professionals to apply 
    (Ex. 3-12). AAOHN states that medical removal works well when it is 
    based on specific biological criteria, such as blood lead levels, but 
    not when it is based on a health care professional's opinion that 
    continued exposure to a contaminant will endanger a worker's health. 
    OSHA disagrees. As noted above, the lead, cadmium, and formaldehyde 
    standards provide for medical removal based on a health care 
    professional's opinion that an employee's existing medical condition 
    will be aggravated by continued exposure to the chemical. OSHA's 
    experience under these standards has shown that the health care 
    professionals who provide medical surveillance have received sufficient 
    guidance from those standards as to when medical removal is 
    appropriate, even when removal is required by medical conditions other 
    than numerical biological triggers. OSHA thus has confidence that the 
    MRP benefits provision in the MC standard, which similarly relies on 
    the informed judgment of health care professionals, will give 
    sufficient guidance to the PLHCPs who will be called upon to make 
    medical removal decisions under the standard.
        Organization Resources Counselors, Inc. (ORC) criticized the MRP 
    benefits provision on the basis that OSHA had not estimated the extent 
    to which MRP benefits will increase worker participation in medical 
    surveillance or what incremental benefits might result (Ex. 3-13). 
    Although OSHA cannot quantify precisely the extent to which MRP 
    benefits will increase participation in medical surveillance, it has 
    been OSHA's experience that substantial numbers of workers will be 
    discouraged from participating in medical surveillance if there is a 
    financial disincentive to such participation. For example, in Phelps 
    Dodge Corp., 11 O.S.H. Cas. (BNA) 1441 (Rev. Comm'n 1983), it was 
    reported that 42% of employees failed to undergo medical examinations 
    when they were required to take the examinations on their personal time 
    and provide their own transportation to and from the hospital. 
    Moreover, the workers who most need medical surveillance are those in 
    poor or marginal health, and such workers are likely to be particularly 
    concerned that a medical examination may result in a recommendation 
    that they be removed from their current job. Because MRP benefits will 
    remove a significant financial disincentive to employees participating 
    in medical surveillance, OSHA expects this final rule to result in a 
    significant increase in the number of workers who cooperate with the 
    medical surveillance provided under the MC standard.
        Paragraph (j)(10) requires the PLHCP to presume that MC exposure 
    below the 8-hour TWA PEL is not likely to aggravate an existing disease 
    of the heart, liver, central nervous system, or skin. Under this 
    paragraph, a PLHCP may still recommend removal of an employee who is 
    exposed below the 8-hour TWA PEL but must cite specific medical 
    evidence to support the recommendation. Absent such evidence, the 
    employer need not remove the employee. The rulemaking record contains 
    no evidence that exposures below the 8-hour TWA PEL will generally 
    aggravate existing cardiac, hepatic, neurological, and skin diseases, 
    and OSHA therefore believes it is appropriate to require the PLHCP to 
    specifically justify a recommendation that an employee exposed below 
    the 8-hour TWA PEL be medically removed. No comments were received 
    concerning this provision.
        When a PLHCP recommends medical removal within the terms of the 
    standard, paragraph (j)(11) requires the employer either to transfer 
    the employee to comparable work where MC exposures are below the action 
    level or to remove the employee from MC exposure. For each employee 
    thus transferred or removed, the employer must maintain the employee's 
    earnings, seniority, and other employment rights and benefits for up to 
    six months. The employer may cease paying MRP benefits before the end 
    of the six-month period upon receipt of a medical determination that 
    the employee's exposure to MC will no longer aggravate any existing 
    cardiac, hepatic, neurological, or dermal disease, or upon receipt of a 
    medical determination concluding that the employee can never return to 
    MC exposure above the action level.
        The final rule also adopts provisions similar to those OSHA has 
    included in previous standards that provide for MRP benefits. These 
    provisions (1) allow an employer to condition an employee's receipt of 
    MRP benefits on participation in follow-up medical surveillance 
    [paragraph (j)(12)(ii)]; (2) provide for a reduction in MRP benefits to 
    offset any workers' compensation indemnity payments the employee 
    receives for the same period of time [paragraph (j)(12)(iii)]; (3) 
    provide an offset of MRP benefits against compensation from a publicly 
    or employer-funded compensation program or income the employee receives 
    from other employment that is made possible by virtue of the employee's 
    removal [paragraph (j)(12)(iv)]; and (4) require the employer to pay 
    MRP benefits if it voluntarily removes or restricts an employee due to 
    the effects of MC exposure on the employee's medical condition 
    [paragraph (j)(13)].
        The Southern Company (Ex. 3-14) contended that OSHA lacks the 
    statutory authority to provide for MRP benefits and that employee wages 
    should be left to the collective bargaining process. However, the Court 
    of Appeals for the D.C. Circuit has upheld OSHA's statutory authority 
    to require employers to provide MRP
    
    [[Page 50716]]
    
    benefits. United Steelworkers v. Marshall, 647 F.2d 1189, 1230 (D.C. 
    Cir. 1980), cert. denied, 453 U.S. 913 (1981). The Court observed that 
    safety issues have traditionally been a subject for collective 
    bargaining but that Congress, by giving OSHA authority to regulate 
    occupational safety and health, expected OSHA regulations to override 
    collective bargaining agreements to the extent necessary to provide 
    safe and healthful workplaces. United Steelworkers, 647 F.2d at 1236. 
    MRP benefits promote worker health by encouraging employees to 
    participate in medical surveillance and thereby become aware of whether 
    they have health problems that could be aggravated by MC exposure. OSHA 
    concludes it has the requisite statutory authority to provide for MRP 
    benefits in the methylene chloride standard.
        The American Association of Occupational Health Nurses (AAOHN) 
    stated that it generally supports removal of employees who are 
    experiencing adverse health effects as a result of workplace exposure 
    to a hazardous material. Ex. 3-12. However, AAOHN recommended that, 
    rather than adopt the MRP provisions, OSHA should strengthen the 
    requirements for engineering controls, work practices, and medical 
    surveillance. AAOHN also suggested that the medical removal provisions 
    are discriminatory and expressed the belief that the Americans with 
    Disabilities Act (ADA) and state workers' compensation statutes provide 
    adequate remedies for individuals with serious diseases that are 
    aggravated by occupational exposure.
        OSHA does not agree with AAOHN that strengthening other provisions 
    of the standard is a viable substitute for MRP benefits. OSHA set the 
    8-hour TWA PEL at the lowest level for which it could document 
    feasibility across the affected application groups. Accordingly, OSHA 
    cannot require employers generally to achieve lower limits through 
    engineering controls and work practices. OSHA notes, however, that the 
    inclusion of MRP benefits under the standard provides an incentive for 
    employers to reduce MC exposures, where feasible, to levels below those 
    required by the standard to minimize the possibility that MC exposure 
    will contribute to or aggravate an employee's existing cardiac, central 
    nervous system, hepatic, or skin disease and thereby require medical 
    removal. The requirement for MRP benefits will therefore encourage 
    employers to minimize MC exposures to the extent it is feasible to do 
    so. Furthermore, medical removal under the final rule is limited to 
    those employees who are particularly vulnerable to MC exposure because 
    they have existing heart, central nervous system, liver, or skin 
    diseases that could be aggravated by continued MC exposure. OSHA 
    believes that, for these especially susceptible employees, removal from 
    MC exposure that could aggravate their diseases is a necessary means of 
    protection.
        OSHA also disagrees with AAOHN's contention that the Americans with 
    Disabilities Act provides adequate remedies for individuals with 
    diseases that would be aggravated by occupational exposure to MC. The 
    ADA requires employers to make reasonable accommodations to an employee 
    with a ``disability,'' which is a physical or mental impairment that 
    substantially limits one of more of the employee's ``major life 
    activities'' [29 CFR 1630.2(g)]. Those major life activities include 
    functions such as caring for oneself, performing manual tasks, walking, 
    seeing, hearing, speaking, breathing, learning, and working [29 CFR 
    1630.2(i)]. The cardiac, neurological, hepatic, and dermal diseases 
    which, if aggravated by MC exposure may qualify an employee for MRP 
    benefits, are not necessarily diseases that limit major life activities 
    as defined in the ADA. Therefore, employees who qualify for MRP 
    benefits under this final rule may not be protected by the ADA.
        Moreover, even if a worker who is entitled to MRP benefits under 
    this final rule would also qualify for ADA protection, the ADA does not 
    necessarily protect that worker against immediate loss of income. The 
    ADA requires an employer to make reasonable accommodations for a worker 
    whose current job presents an unreasonable risk to the employee's 
    health. However, if no reasonable accommodation is possible, the 
    employer is free to discharge that employee (See Appendix to 29 CFR 
    Part 1630). Therefore, the ADA does not provide the same level of 
    assurance as MRP benefits that participation in medical surveillance 
    will not lead to an immediate loss of the worker's income.
        Two commenters in addition to AAOHN (National Air Transportation 
    Association, Ex. 3-9; KAL-AERO, Ex. 3-11) suggested that MRP benefits 
    are not needed because they would duplicate workers' compensation 
    benefits. However, MRP benefits and workers' compensation serve 
    fundamentally different purposes and, in many instances, are not 
    duplicative. Unlike MRP benefits, workers' compensation payments are 
    not a preventive measure available to an employee who must be removed 
    from his or her current job to keep an existing condition from becoming 
    aggravated. Workers' compensation benefits are available only when an 
    employee has already contracted a work-related injury or illness that 
    involves time lost from work and/or medical treatment and has been 
    awarded compensation after submitting a claim.
        The underlying diseases that can be aggravated by continued MC 
    exposure and result in MRP benefits under this final rule are not 
    necessarily work-related, and therefore might not qualify an employee 
    for workers' compensation. For example, an employee with a 
    cardiovascular disease that is wholly unrelated to his or her current 
    employment could not collect workers' compensation benefits for that 
    disease even though MC exposure associated with the current job might 
    aggravate that worker's disease. Although that employee would not be 
    eligible for worker's compensation, he or she would qualify for MRP 
    benefits if there is a medical determination that the employee's 
    cardiovascular disease would be aggravated by continued MC exposure.
        Some diseases that qualify workers for MRP benefits might be work-
    related, thereby making the employees eligible for workers' 
    compensation benefits as well. However, the possibility that, in some 
    cases, an employee is eligible for both MRP benefits and workers' 
    compensation does not negate the need for MRP benefits to encourage 
    employees to participate in medical surveillance. The Court of Appeals 
    for the D.C. Circuit has held that MRP benefits may still be needed 
    even though they may overlap with workers' compensation payments. UAW 
    v. Pendergrass, 878 F.2d 389, 400 (D.C. Cir. 1989). Moreover, new 
    paragraph (j)(12)(iii) of the standard provides that, in cases where 
    both MRP and workers' compensation benefits are payable, the MRP 
    benefits can be reduced by the amount the employee receives for lost 
    wages from workers' compensation. Therefore, the standard ensures that 
    employees are not deterred by a potential loss of income from 
    cooperating with medical surveillance while also ensuring that 
    employers need not provide an employee with MRP benefits and workers' 
    compensation payments that total more than an employee's current 
    earnings.
        New paragraph (j)(14)(i) permits the employer to select the initial 
    physician or other licensed health care professional who will conduct 
    the required medical surveillance and recommend whether an employee 
    must be removed for medical reasons. Where
    
    [[Page 50717]]
    
    the employer does so, new paragraph (j)(14)(ii) allows employees the 
    option of having the recommendation of the employer-selected PLHCP 
    reviewed by a licensed health care professional of the employee's 
    choice. If the two health care professionals disagree, paragraph 
    (j)(14)(iii) provides that the employer and employee shall instruct 
    them to resolve their disagreement. If they are unable to do so, under 
    paragraph (j)(14)(iv) they must jointly designate a third PLHCP, who 
    must be a specialist in the field at issue and whose written opinion, 
    under paragraph (j)(14)(v), is the definitive medical determination 
    under the standard. OSHA believes that the option for such multi-step 
    review is a necessary part of any MRP benefits provision because it 
    strengthens the basis for medical removal determinations and increases 
    employee and employer confidence in those determinations. OSHA has 
    provided for similar multi-step review in all previous standards that 
    included provisions for MRP benefits.
        The Southern Company (Ex. 3-14) contends that multi-step review is 
    ``unwarranted and unnecessary'' and would interfere with state workers' 
    compensation laws that dictate employee choice of physician or that 
    tell employers how occupational illnesses must be diagnosed and 
    treated. As explained above, however, the diseases that can result in 
    medical removal are not necessarily work-related illnesses that qualify 
    for workers' compensation. Moreover, similar multi-step review 
    provisions have been in effect since the lead standard was issued in 
    1978, and OSHA is not aware of any conflicts or inconsistencies between 
    such provisions and state laws.
        OSHA is adopting, in paragraph (j)(11)(i)(B), a provision that is 
    designed to avoid an undue burden that could result if a small business 
    would need to provide MRP benefits to more than one employee at the 
    same time. Under paragraph (j)(11)(i)(B), if one or more employees are 
    already receiving MRP benefits and the employer receives a 
    recommendation for medical removal of an additional employee, and if 
    comparable work that does not involve exposure to MC at or above the 
    action level is not available for that additional employee, the 
    employer need not remove the additional employee if the employer can 
    demonstrate that removal and the costs of MRP benefits to that 
    employee, considering feasibility in relation to the size of the 
    employer's business and the other requirements of this standard, make 
    further reliance on MRP an inappropriate remedy. Although new paragraph 
    (j)(11)(i)(B) is designed to benefit small businesses, it is not 
    explicitly limited to businesses of a certain size because no single 
    size cutoff would be appropriate for all of the employers who might 
    experience feasibility constraints as a result of providing MRP 
    benefits to multiple employees at the same time. However, because 
    feasibility in relation to the size of the business is taken into 
    account in determining whether an employer may retain an employee in 
    his or her present job under paragraph (j)(11)(i)(B), the application 
    of that provision will effectively be limited to relatively small 
    businesses.
        In a case governed by paragraph (j)(11)(i)(B), the employer may 
    retain the additional employee in the existing job until transfer or 
    removal becomes appropriate, provided: (i) the employer or the PLHCP 
    informs the additional employee of the risk to the employee's health 
    from continued MC exposure; and (ii) the employer ensures that the 
    employee receives medical surveillance, including a physical 
    examination, at least every 60 days. OSHA believes that, in the limited 
    circumstances specified in this provision, it is appropriate to allow 
    an employer to retain an employee in his or her present job, even when 
    the PLHCP has recommended removal, provided the employer ensures that 
    the employee receives the more frequent medical surveillance specified 
    in the provision and is fully aware of the health risk. Frequent 
    medical surveillance and full information will enable the employer and 
    employee to take steps to minimize the risk under existing workplace 
    conditions by, for example, implementing those controls that are in 
    place and strictly following work practices that are designed to 
    minimize the employee's MC exposure.
        The American Association of Occupational Health Nurses (Ex. 3-12) 
    suggests that this provision is discriminatory and could expose 
    companies to litigation under the Americans with Disabilities Act 
    (ADA). The AAOHN did not explain in what way this provision would 
    violate the ADA, and OSHA does not believe it would. As discussed 
    above, the workers who qualify for MRP benefits under this final rule 
    are not necessarily ``disabled'' within the meaning of the ADA and, to 
    the extent they are, MRP benefits provide protection to workers that 
    may not be available under the ADA. Moreover, OSHA does not agree with 
    AAOHN that allowing an employer to retain an employee who is eligible 
    for medical removal in his or her current job while one or more other 
    employees are on medical removal is accurately characterized as 
    ``discrimination.'' All employees receive protection from the new MRP 
    benefits provisions beyond that afforded by the current rule. The 
    employee who is retained in his or her present job under paragraph 
    (j)(11)(i)(B) will receive additional protection through enhanced 
    medical surveillance. Paragraph (j)(11)(i)(B) also requires that the 
    employee be informed of the risk to his or her health from continued MC 
    exposure, thereby enabling the employer and employee to take steps 
    necessary to minimize that risk under existing workplace conditions by, 
    for example, implementing those controls that are in place and strictly 
    following work practices designed to minimize the employee's MC 
    exposure.
        Several commenters (Imperial Adhesives, Ex. 3-3; Tupelo Foam Sales, 
    Inc., Ex. 3-6; Diversified Brands, Ex. 3-7) urged OSHA to narrow the 
    MRP provisions to the greatest extent possible to reduce their economic 
    impact. These commenters did not, however, offer specific suggestions 
    as to how the economic impact of the provisions could be narrowed. As 
    discussed below in the final economic analysis, OSHA concludes that 
    addition of the provisions for MRP benefits to the MC standard will 
    have a minimal economic impact on businesses of all sizes. Moreover, 
    paragraph (j)(11)(i)(B) permits an employer to retain an employee who 
    would otherwise need to be removed in his or her present job if the 
    employer can demonstrate that the cost of medical removal would impose 
    an undue economic hardship on the business. OSHA therefore believes 
    that the final rule already reduces the economic impact of MRP benefits 
    to the extent possible while still maintaining the protection those 
    benefits afford to workers.
    
    III. Extensions of Startup Dates.
    
        The motion for reconsideration requested that the standard's 
    current final engineering control startup date of April 10, 2000, which 
    was limited in the final standard to employers with fewer than 20 
    employees, also apply to employers in the specified application groups 
    who have 20-49 employees and to foam fabricators who have 20-149 
    employees. (When the original standard established different startup 
    dates based on an employer's number of employees, OSHA intended for the 
    number of employees to refer to the total number of workers employed by 
    the particular employer, not the number who work at a particular 
    facility or the number that use methylene chloride in their work. The 
    parties to the motion for reconsideration explained in their motion 
    that they also intended this
    
    [[Page 50718]]
    
    definition when they referred to an employer's number of employees). 
    The parties contended that employers in these application groups and 
    size categories, similarly to those with fewer than 20 employees, have 
    limited resources with which to develop and implement engineering 
    controls and will be able to use those resources more efficiently if 
    given additional time to develop and install effective controls and to 
    take advantage of the compliance assistance that OSHA offers. The 
    motion requested shorter extensions of the engineering control dates 
    for larger employers in these application groups.
        The parties further requested that respirator use to achieve the 8-
    hour TWA PEL not be required before the engineering control startup 
    dates for those employers covered by the motion. They contended that 
    workers would be better protected if these employers can concentrate 
    their limited resources on implementing effective engineering controls 
    rather than diverting some of those resources to interim and expensive 
    respiratory protection (i.e., supplied-air respirators) that would no 
    longer be needed a short time later, once full compliance with the 8-
    hour TWA PEL and STEL is achieved by engineering controls.
        In the notice of the motion for reconsideration, OSHA stated that 
    it believed the extensions of the startup dates the parties had 
    requested were justified. The Agency noted that engineering controls, 
    such as local exhaust ventilation, must be properly designed and 
    installed if they are to work properly and provide effective 
    protection. OSHA believed that, for the relatively small employers who 
    would be receiving extensions of the startup dates, additional time to 
    implement engineering controls would enable them to take advantage of 
    compliance assistance that OSHA offers and avoid the uncertainty and 
    expense that would result if each employer attempted to design and 
    implement controls on its own. OSHA further believed that it was 
    appropriate to extend the startup dates for respirator use to achieve 
    the 8-hour TWA PEL to enable the employers receiving that extension to 
    concentrate their resources on developing and implementing engineering 
    controls to reduce airborne concentrations of MC. Based on the comments 
    received and the entire rulemaking record, OSHA is now adopting the 
    requested extensions in paragraph (n) of the final rule.
        Most commenters supported the extensions. The National Air 
    Transportation Association (Ex. 3-9) and KAL-AERO (Ex. 3-11) stated 
    that use of MC-based paint strippers in general aviation aircraft 
    stripping had already declined substantially, and that the extended 
    startup dates for that activity would encourage the complete 
    elimination of MC-based paint strippers by the year 2000. The 
    Polyurethane Foam Association (Ex. 3-10) supported the extensions for 
    foam manufacturers and foam fabricators, noting in particular that 
    extending the startup date for respirator use to meet the 8-hour TWA 
    PEL would permit these industries to focus their resources on 
    developing engineering controls.
        The National Marine Manufacturers Association (Ex. 3-8) urged OSHA 
    to adopt the extensions for boat building. The Association stated that 
    boat builders now use adhesives that contain MC and that additional 
    compliance time is needed to enable them to determine whether it would 
    be safer to substitute MC-free adhesives, which may be flammable, or to 
    continue to use products that contain MC and install engineering 
    controls to reduce MC exposures. Individual companies supporting the 
    extensions for either their own operations or those of their customers 
    included Benco Sales, Inc. (Ex. 3-1), Imperial Adhesives (Ex. 3-3), Mid 
    South Adhesives, Inc. (Ex. 3-4), Tupelo Foam Sales, Inc. (Ex. 3-6), and 
    Diversified Brands (Ex. 3-7).
        Organization Resources Counselors (ORC) was the only commenter 
    opposing the extensions (Ex. 3-13). ORC objected to the deferral of the 
    requirement that the employers covered by the amendments use 
    respiratory protection to achieve the 8-hour TWA PEL until the date 
    that those employers are required to achieve the PEL through 
    engineering controls. ORC notes that MC is a carcinogen and that OSHA 
    has, in its earlier standards for carcinogens, consistently required 
    employers to use respirators to protect employees while engineering 
    controls are being implemented.
        OSHA agrees that interim respirator use while engineering controls 
    are being implemented is desirable, and the Agency acknowledged in the 
    notice that it has required interim respirator use in its past air 
    contaminant standards. However, in all of those earlier standards, air-
    purifying respirators were available that would protect against the 
    contaminant being regulated. For methylene chloride, air-purifying 
    respirators do not provide effective protection because MC quickly 
    penetrates all currently available organic vapor cartridges. For that 
    reason, the MC standard requires that, when respirators are needed, 
    atmosphere-supplying respirators must be provided and used.
        Atmosphere-supplying respirators are a relatively expensive type of 
    respiratory equipment, requiring the employer not only to purchase the 
    respirators themselves but also to install an air compressor and 
    associated ductwork or rent cylinders containing breathing air. In the 
    case of methylene chloride, the situation is complicated by the 
    predominance of relatively small companies among the employers whose 
    employees are currently exposed above the 8-hour TWA PEL. For those 
    small employers, the relatively high cost associated with atmosphere-
    supplying respirators would divert or exhaust resources that can be 
    better spent on developing and installing engineering controls that 
    will permanently and reliably reduce exposures below the 8-hour TWA PEL 
    and STEL. OSHA continues to believe that worker protection is best 
    served by early installation of effective engineering controls and that 
    the smaller employers who are being granted extensions of startup dates 
    by this final rule should therefore be allowed to use their limited 
    resources for engineering controls instead of interim, short-term use 
    of atmosphere-supplying respirators.
        Moreover, as explained in the notice, employees will still receive 
    substantial interim protection against MC exposure under these amended 
    startup dates. The STEL will go into effect as scheduled, and employers 
    will be required to ensure that some combination of engineering 
    controls, work practice controls, and respiratory protection reduce 
    exposures below that level. Workers will therefore be protected against 
    acute health effects associated with high short-term exposure to MC. 
    Moreover, reduction of short-term exposures to below the STEL will, in 
    most cases, reduce 8-hour time-weighted average exposures and will 
    thereby provide workers with some interim protection against the 
    chronic effects of MC exposure. If no 15-minute exposures exceed 125 
    ppm, the 8-hour TWA must by definition be below 125 ppm. In practice, 
    in order to control variable processes such that no excursions above 
    the STEL occur, the average 8-hour concentration may need to be 
    maintained substantially below 125 ppm.
        This final rule also does not delay compliance with the requirement 
    that employers implement feasible work practices to reduce MC 
    exposures. Such controls can achieve significant reductions in MC 
    exposures in many workplaces at low cost. Early implementation of work 
    practice controls will also enable employers to evaluate the extent to 
    which exposures
    
    [[Page 50719]]
    
    can be reduced by such controls and will enable them to better 
    determine the nature and extent of the engineering controls they will 
    need to achieve the 8-hour TWA PEL and STEL. OSHA has developed Fact 
    Sheets identifying feasible work practice controls for several of the 
    application groups that are receiving extensions of the startup dates 
    in this final rule, and many of those work practices would be feasible 
    and useful for workplaces in other application groups as well. Those 
    work practices were listed in the earlier Federal Register notice, 63 
    FR at 24507-08, and are available in a small entity compliance guide, 
    which can be obtained at OSHA's web site, http://www.osha.gov. 
    Furthermore, the remaining protections of the standard (regulated 
    areas, protective work clothing and equipment, hygiene facilities, 
    hazard communication, employee information and training, and 
    recordkeeping) are already in effect for all employers.
        ORC (Ex. 3-13) contends that the final rule does not afford 
    employees sufficient interim protection because it interprets the rule 
    to excuse employers from all use of atmosphere-supplying respirators. 
    However, these amendments do not alter the requirement that employers 
    achieve the STEL and, if necessary, use atmosphere-supplying 
    respirators to do so. This final rule only extends the startup date for 
    using engineering controls and respirators to achieve the 8-hour TWA 
    PEL. Because the STEL will be in effect as originally scheduled, all 
    employers, including those receiving extensions of startup dates to 
    achieve the 8-hour TWA PEL in this final rule, already need to ensure 
    that employee exposures do not exceed the STEL through some combination 
    of engineering controls, work practices, and atmosphere-supplying 
    respirators.
        ORC also questions whether employers will know when exposures 
    exceed the STEL because the odor threshold of MC is well above the STEL 
    of 125 ppm. OSHA notes that employers may not rely on the odor of MC to 
    determine whether the STEL is exceeded but must, under paragraph (d) of 
    the standard, conduct exposure monitoring that accurately characterizes 
    the short-term concentrations to which their employees are exposed. 
    Paragraph (d) requires the employer to take ``one or more personal 
    breathing zone air samples which indicate the highest likely 15-minute 
    exposures during such operations for at least one employee in each job 
    classification in the work area during every work shift, and the 
    employee sampled [must be the employee] expected to have the highest MC 
    exposure [within the job classification].''
        OSHA is concerned, however, that employers who are required only to 
    comply with the STEL and not with the 8-hour TWA PEL during the interim 
    period created by these amendments may not have adequate information to 
    determine whether they are in fact in compliance with the STEL 
    requirement. Under the current standard, if initial measurements for 
    all job classifications (representing the employee in each job 
    classification with the highest short-term exposure) are below the 
    STEL, no additional (periodic) STEL monitoring is required. In the 
    unusual interim period created by these amendments, during which time 
    controls may not have been implemented to ensure that TWA exposures are 
    below the PEL, a single STEL measurement may be inadequate to ensure 
    that employees are receiving adequate interim protection. To assure 
    that STEL monitoring is conducted with sufficient frequency to 
    characterize employees' short term exposures until compliance with the 
    8-hour TWA PEL is achieved, OSHA is amending Table 1 in the MC standard 
    to require each employer who is receiving an extended startup date in 
    this final rule to conduct quarterly STEL monitoring, during the period 
    covered by that extension, when its 8-hour TWA exposures are above the 
    PEL. Those employers must already conduct quarterly STEL monitoring if 
    their initial measurements show exposures above the STEL. The amendment 
    to Table 1 thus extends the requirement for quarterly monitoring to 
    those employers whose initial measurements are below the STEL.
        The purpose of this additional STEL monitoring is to provide 
    ongoing information, to those employers whose monitoring results show 
    exposures above the 8-hour TWA PEL but below the STEL, that their 
    employees continue to be exposed below the STEL. For this purpose, it 
    is sufficient if those employers conduct the additional monitoring for 
    the highest-exposed employee within the single job classification shown 
    to have the highest short-term exposures. Moreover, because this 
    additional STEL monitoring is intended to apply only to those employers 
    whose 8-hour TWA exposures exceed the PEL, those employers who are 
    required to conduct additional STEL monitoring by this amendment need 
    only conduct such monitoring until they are required to be in full 
    compliance with the 8-hour TWA PEL or until they are in fact in 
    compliance with the 8-hour TWA PEL. Any employer whose initial 8-hour 
    TWA exposures are below the PEL need not conduct any additional STEL 
    monitoring under this amendment.
        Normally, the last sentence of the note to paragraph (d)(3) allows 
    an employer to discontinue all STEL monitoring for employees where at 
    least two consecutive measurements taken at least 7 days apart are at 
    or below the STEL. This provision does not apply to the additional 
    monitoring required by this amendment which, according to amended Table 
    1, must be conducted ``without regard to the last sentence of the note 
    to paragraph (d)(3).'' Once the compliance dates established by these 
    amendments have passed for a particular employer or that employer has 
    achieved compliance with the 8-hour TWA PEL, whichever comes first, the 
    additional monitoring required by these amendments no longer applies, 
    and the note to paragraph (d)(3) would allow that employer to 
    discontinue periodic STEL monitoring for those employees whose 
    exposures are shown to be at or below the STEL by two consecutive 
    measurements taken at least seven days apart. Any TWA or STEL 
    monitoring required after these compliance dates have passed must 
    include each job classification and each shift that does not qualify 
    for discontinuance of monitoring under the note to paragraph (d)(3).
        ORC further contends (Ex. 3-13) that it is inappropriate for OSHA 
    to reconsider its earlier rulemaking decisions at the behest of parties 
    who have challenged the standard in court. ORC argues that the 
    possibility of settling litigation over the standard should not induce 
    OSHA to reconsider or change its earlier rulemaking judgments.
        OSHA believes that ORC is mistaken in suggesting that OSHA should 
    be unwilling to reconsider its rulemaking judgments when asked to do so 
    by parties who are challenging the rule in court. Agencies have both 
    the right and the duty to reconsider their decisions if they are 
    persuaded that a different course of action would better serve the 
    statutory purpose. Such requests for reconsideration often come from 
    parties who have brought judicial challenges to a rule because these 
    parties are typically the parties who have the greatest interest in the 
    rule and who were most active in the rulemaking proceeding. Here, labor 
    and industry organizations who had been active participants in the 
    rulemaking presented OSHA with a well-supported motion for 
    reconsideration of certain narrow aspects of the methylene chloride 
    standard. Those parties also stated that they would withdraw their 
    judicial
    
    [[Page 50720]]
    
    challenges if OSHA amended the standard along the lines they requested. 
    Upon evaluating the motion, OSHA tentatively concluded that the changes 
    the parties sought were justified and afforded the public an 
    opportunity to comment on those changes.
        Having considered the entire rulemaking record, including the 
    comments it received in response to the reopening of the record, OSHA 
    concludes that the amendments it is making in this final rule serve the 
    statutory purpose of protecting employees while avoiding excessive 
    economic burdens on employers, particularly small employers. As 
    discussed above, OSHA believes that the addition of MRP benefits to the 
    standard will increase employee participation in the standard's medical 
    surveillance provisions and thereby ensure that employees are aware of 
    medical conditions that could be aggravated by continued MC exposure. 
    OSHA further believes that the extensions of startup dates being 
    granted to some employers will benefit workers by improving the ability 
    of those employers to comply with the standard. The cornerstone of the 
    standard, the 8-hour TWA PEL of 25 ppm, is not being altered by these 
    amendments. OSHA is issuing these amendments because it believes they 
    are justified by the record and will better effectuate the purposes of 
    the Act, not because the Agency is seeking to resolve legal challenges 
    to the methylene chloride standard.
        OSHA does, however, believe that the potential withdrawal of the 
    parties' judicial challenges to the MC standard is a positive benefit. 
    Litigation over earlier standards has hindered OSHA's achievement of 
    its statutory duty to protect the health and safety of workers. In some 
    cases, OSHA standards have been vacated by the courts (e.g., AFL-CIO v. 
    OSHA, 965 F.2d 962 (11th Cir. 1992), and vacated standards cannot 
    protect worker health or safety. Some standards have also been stayed 
    during judicial review (e.g., United Steelworkers v. Marshall, 647 F.2d 
    1189, 1202 (D.C. Cir. 1980), cert. denied, 453 U.S. 913 (1981)), 
    thereby delaying the protection afforded by those standards. In other 
    cases, courts have required OSHA to reconsider certain aspects of its 
    standards (e.g., Building & Constr. Trades Dep't v. Brock, 838 F.2d 
    1258 (D.C. Cir. 1988)), and the additional rulemaking proceedings 
    required by such court orders have delayed implementation of important 
    parts of the rule and have diverted OSHA's resources from other 
    important projects. In carrying out its statutory mandate, OSHA cannot 
    ignore the adverse impact that might result from litigation over its 
    standards. However, any modifications to a standard suggested by a 
    litigant or any other person must be justified on their merits and must 
    assure adequate worker protection. That is the case here, and OSHA is 
    therefore including in the final rule the requirements suggested by the 
    parties to the motion for reconsideration.
    
    IV. Final Economic and Regulatory Flexibility Analysis
    
        OSHA is revising paragraph (j), Medical Surveillance, of the final 
    rule governing occupational exposure to methylene chloride (MC) (29 CFR 
    1910.1052) to add medical removal protection benefits to the rule. This 
    final economic analysis estimates the costs of complying with the final 
    MRP provisions and then assesses the economic feasibility and potential 
    economic impacts of these costs on firms in the affected sectors. The 
    information used in this analysis is taken from the exposure profile, 
    industry profile, and economic impacts analysis presented in the Final 
    Economic Analysis (Ex. 129) that accompanied OSHA's final rule for 
    methylene chloride (62 FR 1494-1619, January 10, 1997). Relying on the 
    data developed for that analysis to support this revision to the final 
    rule ensures analytical consistency and comparability across the two 
    economic analysis documents.
        OSHA's final MC rule did not contain medical removal protection 
    provisions. The amendments being made today respond to a motion for 
    reconsideration filed by the United Auto Workers (UAW), the Halogenated 
    Solvents Industry Alliance, Inc., and others. As requested in that 
    motion, OSHA is adding paragraphs (j)(9)(i)(A) and (B), (j)(10), 
    (j)(11), (j)(12), (j)(13), and (j)(14), dealing with medical removal 
    protection, medical removal protection benefits, voluntary removal or 
    restriction of an employee, and multiple health care professional 
    review, respectively, to the final rule. Medical removal protection 
    (MRP) applies only under certain limited circumstances, i.e., medical 
    removal protection would be required only if a physician or other 
    licensed health care professional finds that exposure to MC may 
    contribute to or aggravate the employee's existing cardiac, hepatic, 
    neurological (including stroke), or dermal disease. The rule instructs 
    the physician or other licensed health care professional to presume 
    that a medical condition is unlikely to require removal from exposure 
    to MC, unless medical evidence indicates to the contrary, if the 
    employee is not exposed to MC at concentrations above the 8-hour TWA 
    PEL of 25 ppm. The physician or other licensed health care professional 
    may also recommend removal from exposure to MC for any other condition 
    that would, in the health care professional's opinion, place the 
    employee's health at risk of material impairment from exposure to MC, 
    but MRP would only be triggered by a finding that exposure to MC may 
    contribute to or aggravate the employee's existing cardiac, hepatic, 
    neurological (including stroke), or dermal disease.
        Any employee medically removed must (1) be provided with comparable 
    work where MC exposures are below the action level, or (2) be 
    completely removed from MC exposure. The employee's total pay, benefits 
    and seniority must be maintained throughout the period of medical 
    removal protection, even if the only way to remove the employee from MC 
    exposure is to send him or her home for the duration of the medical 
    removal protection period. The employer may reduce the amount paid to 
    the removed worker to the extent that the worker's previous pay has 
    been offset by other compensation (such as worker's compensation 
    payments) or by wages from another job made possible by the medical 
    removal.
        The final rule requires employers to maintain medical removal 
    protection benefits for up to six months. Medical removal protection 
    may be terminated in less than 6 months if a medical determination 
    shows that the employee may return to MC exposure, or a medical 
    determination is made that the employee can never return to MC 
    exposure.
        In situations in which no comparable work is available for the 
    medically removed employee, the rule allows the employer to demonstrate 
    that the medical removal and the costs of medical removal protection 
    benefits, considering feasibility in relation to the size of the 
    employer's business and the other requirements of this standard, make 
    reliance on medical removal protection an inappropriate remedy. In such 
    a situation, the employer may retain the employee in the existing job 
    until transfer or removal becomes appropriate, provided that the 
    employer ensures that the employee receives additional medical 
    surveillance, including a physical examination at least every 60 days 
    until removal or transfer occurs, and that the employer or PLHCP 
    informs the employee of the risk to the employee's health from 
    continued MC exposure.
    
    [[Page 50721]]
    
        In conducting this economic analysis, OSHA has estimated the number 
    of workers with the four listed types of conditions (neurological, 
    hepatic, cardiac, and dermal disease) that can trigger MRP. OSHA has 
    assumed that medical removal protection would be extended only to 
    employees exposed above the PEL, as reflected by the presumption. This 
    analysis also assumes that all employers will provide medical removal 
    protection whenever a physician or other licensed health care provider 
    recommends removal, i.e., OSHA has not quantified the number of times 
    small firms may retain an employee for whom a removal recommendation 
    has been made in the employee's existing job due to the employer's 
    financial inability (i.e., economic infeasibility) to remove the 
    employee. Because some very small firms may find that medical removal 
    protection is infeasible in their circumstances but this cost analysis 
    assumes that all such employees will be removed, OSHA believes that 
    this analysis is likely to overestimate the costs associated with MRP.
    
    Costs of Medical Removal Protection Provisions
    
        OSHA's estimates of the costs of the medical removal protection 
    provisions are calculated based on the number of workers eligible for 
    medical removal protection times the frequency of the medical 
    conditions that would trigger medical removal protection in the exposed 
    population times the costs of medical removal protection for each type 
    of medical condition.
    
    Number of Workers Eligible for Medical Removal Protection Under the 
    Final Rule
    
        Because of the presumption stated explicitly in paragraph 
    (j)(11)(i)(B), medical removal protection will be limited in almost all 
    cases to employees exposed to MC at concentrations above the PEL of 25 
    ppm as an 8-hour TWA. The Final Economic Analysis (Ex. 129) estimated 
    that approximately 55,000 employees in all affected application groups 
    are currently exposed above 25 ppm. This estimate is used here to 
    calculate the number of employees potentially eligible for medical 
    removal protection during the year in which medical removal protection 
    will be in effect but the engineering control requirements of the rule 
    will not yet be in effect for some of the application groups. Once the 
    implementation of engineering controls is required, OSHA assumes, for 
    the purposes of this analysis, that 10 percent of those employees 
    previously exposed to an 8-hour TWA above 25 ppm (5,500 employees) 
    would continue to be exposed to an 8-hour TWA above 25 ppm.
        OSHA believes that reliance on these assumptions will lead to an 
    overestimate of the number of employees eligible for medical removal 
    protection because some firms will have implemented controls and 
    lowered the exposures of their employees well before the final standard 
    requires them to do so. Once the standard requires employers to 
    implement engineering controls, OSHA's Final Economic Analysis (Ex. 
    129) estimated that the exposure of almost all employees would be 
    reduced to MC levels below 25 ppm as an 8-hour TWA. To capture all 
    costs potentially associated with the medical removal protection 
    provisions, OSHA has assumed for this analysis that some employees will 
    continue to be exposed above 25 ppm.
    
    Frequency of Medical Removal Protection Under the Final Rule
    
        Paragraph (j)(11)(i) of the final rule provides for medical removal 
    protection if there is a medical determination that exposure to 
    methylene chloride ``may contribute to or aggravate existing cardiac, 
    hepatic, neurological (including stroke), or skin disease.'' Medical 
    removal protection does not apply if the condition is such that removal 
    from MC exposure must be permanent.
        OSHA believes that MC-induced or aggravated neurological symptoms 
    (other than stroke) occur infrequently and that when such protection is 
    triggered by neurological manifestations (other than stroke), the 
    period of time involved in the removal will be relatively brief. OSHA 
    also believes that MC-induced or aggravated heart conditions or strokes 
    are likely to result in permanent medical removal, and thus that 
    employers will not incur the costs of medical removal protection in 
    these cases. This analysis therefore focuses on medical removal 
    protection for MC-induced or aggravated dermatitis or abnormal hepatic 
    conditions. Each of these conditions is likely to resolve with time, 
    proper treatment, or both, and these are therefore the conditions 
    likely to result in a determination that temporary medical removal 
    protection, rather than permanent removal, is needed.
        Because the final rule would provide for medical removal protection 
    in situations where exposure to MC contributes to or aggravates the 
    listed condition, this analysis focuses on the frequency with which 
    each covered condition occurs in the working population, and not simply 
    on the frequency with which MC causes these conditions. OSHA has no 
    evidence that hepatic conditions are more prevalent in workplaces that 
    use MC than in the general working age population and therefore assumes 
    that the prevalence of hepatic conditions will be the same as in the 
    general working age population (ages 18-65). OSHA thus estimates that 5 
    percent of the working population will be found on evaluation to have 
    hepatic conditions sufficiently abnormal to trigger medical removal.
        For dermatitis, which is seldom a lasting condition, OSHA similarly 
    assumes, in the absence of evidence to the contrary, that the 
    prevalence in the MC-exposed workforce is the same as the rate in the 
    general working age population. For dermatitis, Vital and Health 
    Statistics (National Center for Health Statistics, 1995) reports that, 
    in 1993, the prevalence of dermatitis was 2.93 percent for persons 
    between 18 and 45 and 2.18 percent for persons between 45 and 65. 
    Weighting using the BLS data cited above, OSHA finds that 2.7 percent 
    of the MC-exposed workforce will be found on the first required medical 
    evaluation to have dermatitis and will be medically removed.
        After the standard has been in effect for the first year, OSHA 
    assumes that the prevalence of dermatitis will continue at the same 
    rate. For liver conditions, OSHA assumes that most of the conditions 
    that triggered removal in the first year will have been resolved and 
    that the number of older cases that flare up and have to be treated 
    again, combined with new cases that trigger medical removal, will occur 
    at a combined rate \1/5\ that of the initial rate.
    
    Costs of Medical Removal Protection
    
        Employers incur three kinds of costs for medical removal 
    protection: costs for medical evaluations not already required; costs 
    resulting from changing the employee's job, such as those related to 
    retraining and lost productivity; and, where alternative jobs that do 
    not involve MC exposure are not available, the costs of keeping a 
    worker who is not working on the payroll.
        Employers may incur costs for medical evaluations (over and above 
    those already required for medical surveillance) for two reasons: to 
    determine if the employee can return to work, and to determine, using 
    multiple PLHCP review, whether the initial medical determination was 
    correct. Because the final rule allows employees to be removed from 
    medical removal protection status only on the basis of a new medical 
    determination, every instance of medical removal protection will 
    require one additional examination.
    
    [[Page 50722]]
    
    OSHA estimated the cost of a medical examination at $130 in the Final 
    Economic Analysis (Ex. 129). Every case of medical removal protection 
    would require at least one additional medical evaluation. In addition, 
    OSHA estimates that 10 percent of all removed cases will require a 
    second medical evaluation either for the purpose of multiple health 
    care professional review or because the first examination showed that 
    the employee could not yet be returned to normal duty.
        The largest MRP-related costs in almost all cases will be the cost 
    of paying for time away from work for the removed employee. OSHA 
    estimates that the typical dermatitis case will involve 6 days away 
    from work. BLS (BLS, Occupational Injuries and Illnesses: Counts, 
    Rates, and Characteristics, 1994) reports that, in 1994, the typical 
    lost worktime case of dermatitis involved 3 days away from work. OSHA 
    allowed an additional three days to allow time for a return-to-work 
    determination to be made. For medical removal for hepatic conditions, 
    OSHA estimates that a 4-week period of medical removal will normally be 
    sufficient to provide for stabilization and a return to the normal 
    range for the typical case of elevated liver enzymes. Because almost no 
    cases will be resolved in less than 4 weeks and a small number of cases 
    (such as those involving serious liver disease) may take much longer to 
    resolve, OSHA's cost estimate estimates 5 weeks as the average period 
    of medical removal for these cases.
        For the short-term medical removal associated with dermatitis, OSHA 
    has conservatively assumed that the employee will be paid full wages 
    and benefits even though not at work. For the longer term medical 
    removal associated with hepatic conditions, OSHA estimates that, in 
    firms with more than 20 employees, alternative jobs not involving 
    exposure to MC will be found for affected employees. OSHA estimates the 
    costs of moving employees to alternative jobs as equivalent to the loss 
    of 20 person hours in lost productivity and/or retraining expenses. For 
    firms with fewer than 20 employees, OSHA expects that there may be more 
    difficulty finding alternative positions both because fewer alternative 
    positions are available and because more positions in the establishment 
    are likely to involve exposure to MC.
        For the very small firms in furniture stripping, where all jobs may 
    involve exposure to MC, OSHA has assumed that all cases of medical 
    removal will involve removing employees from work entirely, and thus 
    that employers will incur the full costs of the employee's wages and 
    benefits for the five weeks the employee is medically removed. Firms 
    with fewer than 20 employees in other application groups tend to be 
    somewhat larger than in furniture stripping and will therefore be more 
    likely to have work that does not involve exposure to MC at levels 
    above the action level. For example, in such small-business-dominated 
    application groups as printing shops, and in small cold cleaning and 
    paint stripping operations, exposure to MC tends to involve only a 
    single employee and is commonly intermittent even for that employee. 
    For establishments with fewer than 20 employees in application groups 
    other than furniture stripping, OSHA estimates that 50% will be able to 
    find alternative employment and 50% will need to send the employee home 
    because alternative jobs without MC exposure cannot be found.
    
    Annualized Cost Estimates
    
        Table 1 shows OSHA's estimated annualized costs for firms in each 
    application group. The total annualized costs for medical removal 
    protection are estimated to be $920,387 per year for all affected 
    employers. The greatest costs are in the cold cleaning application 
    group, the all other industrial paint stripping application group, the 
    construction application group, and the furniture stripping application 
    group. All of these application groups have annualized MRP costs in 
    excess of $100,000 per year.

    Potential Cost Savings of the Revisions
    
        OSHA is also altering several provisions concerning the 
    implementation dates for engineering controls and respiratory 
    protection for employers engaged in selected activities. Paragraphs 
    (n)(2)(A), (B), and (C) provide new implementation dates for 
    engineering controls for employers engaged in these selected 
    activities. Under paragraph (n)(3)(E), these same employers would also 
    now be allowed until the implementation date for engineering controls 
    to meet the rule's requirements for respiratory protection to meet the 
    PEL, i.e., the implementation dates for engineering controls and 
    respiratory protection would be the same for employers engaged in these 
    activities.
        Qualified employers who choose the option of postponing the 
    implementation of engineering controls and respiratory protection would 
    be required by the final rule to conduct STEL monitoring quarterly 
    until either the implementation date for engineering controls and 
    respiratory protection or the date by which they in fact achieve 
    compliance with the 8-hour TWA PEL. The employers affected by these 
    extensions of the implementation dates for engineering controls and 
    respiratory protection, and thus by the final rule's requirements for 
    quarterly STEL monitoring, are employers with employees exposed above 
    the PEL who are engaged in foam fabrication; furniture stripping; 
    general aviation aircraft stripping; product formulation; adhesive 
    users using adhesives for boat building and repair, recreational 
    vehicle manufacture, van conversions, and upholstering; and 
    construction work for restoration and preservation of building, 
    painting and paint removal, cabinet making, and/or floor refinishing.
        OSHA cannot fully evaluate the cost saving effects of these 
    implementation date postponements because OSHA's Final Economic 
    Analysis (Ex. 129) did not provide the data needed to estimate the 
    number of employers in the size classes identified by the final rule 
    for each of the activities affected by the final rule. (OSHA's Final 
    Economic Analysis did analyze impacts on employers of all sizes, but 
    sometimes aggregated them into larger activity groups or different size 
    classes than those specified in these provisions.) OSHA has, however, 
    developed an estimate of the potential cost savings using certain 
    simplifying assumptions. First, OSHA assumes that all employers in the 
    affected application groups will be affected. The effect of this 
    assumption is to include some employers who would not qualify because 
    they do not engage in the prescribed activity, e.g., the estimate 
    includes cost savings for facilities using adhesives for activities 
    other than those specified, i.e., for activities other than boat 
    building and repair, recreational vehicle manufacturing, van conversion 
    or upholstering. This assumption will thus overestimate the cost 
    savings.
        OSHA also assumes that no employers will need to install 
    engineering controls or use respiratory protection in order to meet the 
    STEL requirements of the standard. OSHA is uncertain about how many 
    such employers there are, and thus cannot quantify the extent to which 
    this assumption overestimates cost savings. Finally, OSHA assumes that 
    the effect of these provisions of the final rule is that employers of 
    employees currently exposed above the PEL in the affected application 
    groups will not incur the costs of respiratory protection for the two 
    years before they are required to install engineering controls, but 
    will have to provide quarterly monitoring for the STEL during this 
    period.
        For each affected employee, the employer would save the costs of 
    installing and maintaining an air-supplied respirator and an air 
    compressor for two years. The Final Economic Analysis (Ex. 129) 
    estimates the annual costs of such respirators as $679 per year. 
    Offsetting this cost savings of $679 per year for each of two years is 
    the cost of quarterly STEL monitoring during that same time period. 
    Based on its Final Economic Analysis (Ex. 129), OSHA estimates the cost 
    of STEL monitoring at these facilities to be $80 for two badge samples. 
    Annual costs for quarterly monitoring would thus be $320 per year (4 
    times $80). The total cost savings are thus $359 ($679 minus $320) per 
    affected employee per year. OSHA estimates, based on the exposure 
    profile in its Final Economic Analysis (Ex. 129), that there are 18,000 
    affected employees who are engaged in the activities specified in these 
    provisions. Considering all 18,000 affected employees, these provisions 
    will provide cost savings of $6.4 million per year for each of two 
    years (18,000 employees times $359 per employee). Annualized over ten 
    years at a seven percent discount rate, this represents a potential 
    cost savings of $960,000 per year.
        Because this estimate of potential cost savings is based on 
    assumptions that may overestimate the cost savings of the revisions to 
    the final rule, OSHA is not using this estimate of cost savings to 
    offset the costs of MRP in its cost and economic impact analysis. This 
    means that the costs reflected in this analysis will be overstated to 
    some extent after these amendments go into effect.
    
    Economic Impacts
    
        Table 2 combines the cost data from Table 1 and the economic 
    profile information provided in the Final Economic Analysis for the 
    Methylene Chloride rule (Ex. 129) to provide estimates of the potential 
    impacts of these compliance costs on firms in affected application 
    groups. The medical removal protection required by the final rule is 
    clearly economically feasible: on average, annualized compliance costs 
    amount only to 0.0014 percent of estimated sales and 0.03 percent of 
    profits. These impacts do not take into account the cost savings 
    described above. For all but one application group--furniture 
    stripping--compliance costs are less than 0.07 percent of profits, and 
    less than 0.003 percent of the value of sales. Even in furniture 
    stripping, the annualized costs of medical removal protection are still 
    only 0.015 percent of sales and 0.3 percent of profits. Impacts of this 
    magnitude do not threaten the economic feasibility of firms in any 
    affected application group. If highly unusual circumstances were to 
    arise that pose such a threat, the standard allows specifically for the 
    cost impact to be considered on a case-by-case basis.

    BILLING CODE 4510-26-C
    
    [[Page 50726]]
    
        OSHA's cost methodology for this final rule tends to overestimate 
    the costs and economic impacts of the standard for several reasons. 
    First, as discussed in the section on potential cost savings, OSHA has 
    not taken into account the cost savings some employers will realize 
    from the extended implementation dates that are permitted by the final 
    rule.
        Other aspects of OSHA's methodology also tend to result in cost 
    overestimates. OSHA's use of general population prevalence data to 
    estimate the prevalence of conditions that might lead to medical 
    removal overestimates costs by ignoring the possibility that workers in 
    MC establishments may be healthier than the general population, i.e., 
    it ignores the ``healthy worker'' effect. OSHA has also assumed that 
    all unusual hepatic conditions will lead to medical removal, when in 
    many cases no medical removal protection will be necessary. Finally, 
    OSHA has also included in its cost estimate all cases involving medical 
    removal, when it is in fact likely that some smaller firms would be 
    able to argue that the cost of extending MRP benefits to an additional 
    employee would not be feasible (and would therefore make reliance on 
    MRP an inappropriate remedy), and thereby avoid removing that 
    additional employee, as allowed by paragraph (j)(11)(i)(B).
    
    Regulatory Flexibility Screening Analysis and Certification
    
        Tables 3 and 4 provide a regulatory flexibility screening analysis. 
    As in the analysis for all firms in Table 2, OSHA used the cost data 
    presented in Table 1 in combination with the data on small firms 
    presented in the Final Economic Analysis (Ex. 129). Table 3 shows 
    annualized compliance costs as a percentage of revenues and profits 
    using SBA definitions of small firms for each relevant SIC code within 
    each application group. This analysis shows that costs as a percentage 
    of revenues and profits are slightly greater than is the case for all 
    firms in the SIC, but still average only 0.0017 percent of revenues and 
    0.035 percent of profits. The most heavily impacted industry is 
    furniture stripping, but the impacts in this group are the same for all 
    firms in the group because all furniture stripping firms are small 
    using the SBA definition.

        As noted in the discussion of costs, firms with fewer than 20 
    employees are much more likely to incur greater costs for medical 
    removal protection because such firms may have difficulty in finding a 
    job that does not involve exposure to MC at levels above the action 
    level. OSHA therefore examined annualized compliance costs as a 
    percentage of sales and profits for firms with fewer than 20 employees.
        Table 4 shows the results of this analysis. For the typical 
    affected firm with fewer than 20 employees, the annualized costs of 
    medical removal protection represent 0.0026 percent of sales and 0.064 
    percent of profits. Furniture stripping has the greatest potential 
    impacts--annualized costs are 0.016 percent of sales and 0.3 percent of 
    profits for firms in this application group. These impacts do not 
    constitute significant impacts, as envisioned by the Regulatory 
    Flexibility Act. However, because unusually prolonged medical removal 
    without an alternative job within the establishment might present 
    problems for these very small firms, the standard includes a provision 
    [paragraph (j)(11)(i)(B)] requiring special consideration of the 
    feasibility of, economic burden imposed by, medical removal protection 
    when an employer would otherwise need to provide MRP benefits to more 
    than one employee. This provision ensures that impacts are not unduly 
    burdensome even in rare and unusual circumstances. Therefore, based on 
    its analyses both of impacts and small firms using the SBA definitions, 
    and of very small firms with fewer than 20 employees, OSHA certifies 
    that the MRP provisions in this final rule will not have a significant 
    impact on a substantial number of small entities.
    
    V. Federalism
    
        This final rule has been reviewed in accordance with Executive 
    Order 12612 (52 FR 41685, October 30, 1987), regarding Federalism. This 
    Order requires that agencies, to the extent possible, refrain from 
    limiting State policy options, consult with States prior to taking any 
    actions that would restrict State policy options, and take such actions 
    only when there is a clear constitutional authority and the presence of 
    a problem of national scope. The Order provides for preemption of State 
    law only if there is a clear Congressional intent for the Agency to do 
    so. Any such preemption is to be limited to the extent possible.
        Section 18 of the Occupational Safety and Health Act (OSH Act) 
    expresses Congress' intent to preempt state laws relating to issues for 
    which Federal OSHA has issued occupational safety and health standards. 
    Under the OSH Act, if an occupational safety or health issue is 
    addressed by an OSHA standard, a State law addressing the same issue is 
    preempted unless the State submits, and obtains Federal OSHA approval 
    of, a plan for the development of occupational safety and health 
    standards and their enforcement. Occupational safety and health 
    standards developed by such State-Plan States must, among other things, 
    be at least as effective in providing safe and healthful employment and 
    places of employment as the Federal standards. Where such standards are 
    applicable to products distributed or used in interstate commerce, they 
    may not unduly burden commerce and must be justified by compelling 
    local conditions.
        This final MC rule revises the current MC standard by adding a 
    provision for limited medical removal protection benefits and by 
    extending certain startup dates for employers who use MC in certain 
    applications. As under the current MC standard, states with 
    occupational safety and health plans approved under section 18 of the 
    OSH Act will be able to develop their own State standards to deal with 
    any special problems which might be encountered in a particular state 
    while ensuring that their standards are at least as effective as the 
    Federal standard.
    
    VI. State Plans
    
        The 23 States and two territories with their own OSHA-approved 
    occupational safety and health plans must adopt a comparable standard 
    within six months of the publication of this final rule or amend their 
    existing standards to ensure that their standards are ``at least as 
    effective'' as the Federal MC standard as amended by this final rule. 
    Those states and territories are: Alaska, Arizona, California, 
    Connecticut (for State and local government employees only), Hawaii, 
    Indiana, Iowa, Kentucky, Maryland, Michigan, Nevada, New Mexico, New 
    York (for State and local government employees only), North Carolina, 
    Oregon, Puerto Rico, South Carolina, Tennessee, Utah, Vermont, 
    Virginia, the Virgin Islands, Washington, and Wyoming.

    [Note to paragraph (d)(3): The employer may decrease the frequency 
    of 8-hour TWA exposure monitoring to every six months when at least 
    two consecutive measurements taken at least seven days apart show 
    exposures to be at or below the 8-hour TWA PEL. The employer may 
    discontinue the periodic 8-hour TWA monitoring for employees where 
    at least two consecutive measurements taken at least seven days 
    apart are below the action level. The employer may discontinue the 
    periodic STEL monitoring for employees where at least two 
    consecutive measurements taken at least 7 days apart are at or below 
    the STEL.]

        (j) Medical surveillance.
    * * * * *
        (9) Written medical opinions.
        (i) * * *
        (A) The physician or other licensed health care professional's 
    opinion concerning whether exposure to MC may contribute to or 
    aggravate the employee's existing cardiac, hepatic, neurological 
    (including stroke) or dermal disease or whether the employee has any 
    other medical condition(s) that would place the employee's health at 
    increased risk of material impairment from exposure to MC.
        (B) Any recommended limitations upon the employee's exposure to MC, 
    including removal from MC exposure, or upon the employee's use of 
    respirators, protective clothing, or other protective equipment.
    * * * * *
        (10) Medical Presumption. For purposes of this paragraph (j) of 
    this section, the physician or other licensed health care professional 
    shall presume, unless medical evidence indicates to the contrary, that 
    a medical condition is unlikely to require medical removal from MC 
    exposure if the employee is not exposed to MC above the 8-hour TWA PEL. 
    If the physician or other licensed health care professional recommends 
    removal for an employee exposed below the 8-hour TWA PEL, the physician 
    or other licensed health care professional shall cite specific medical 
    evidence, sufficient to rebut the presumption that exposure below the 
    8-hour TWA PEL is unlikely to require removal, to support the 
    recommendation. If such evidence is cited by the physician or other 
    licensed health care professional, the employer must remove the 
    employee. If such evidence is not cited by the physician or other 
    licensed health care professional, the employer is not required to 
    remove the employee.
        (11) Medical Removal Protection (MRP).
        (i) Temporary medical removal and return of an employee.
        (A) Except as provided in paragraph (j)(10) of this section, when a 
    medical determination recommends removal because the employee's 
    exposure to MC may contribute to or aggravate the employee's existing 
    cardiac, hepatic, neurological (including stroke), or skin disease, the 
    employer must provide medical removal protection benefits to the 
    employee and either:
        (1) Transfer the employee to comparable work where methylene 
    chloride exposure is below the action level; or
        (2) Remove the employee from MC exposure.
        (B) If comparable work is not available and the employer is able to 
    demonstrate that removal and the costs of extending MRP benefits to an 
    additional employee, considering feasibility in relation to the size of 
    the employer's business and the other requirements of this standard, 
    make further reliance on MRP an inappropriate remedy, the employer may 
    retain the additional employee in the existing job until transfer or 
    removal becomes appropriate, provided:
        (1) The employer ensures that the employee receives additional 
    medical surveillance, including a physical examination at least every 
    60 days until transfer or removal occurs; and
        (2) The employer or PLHCP informs the employee of the risk to the 
    employee's health from continued MC exposure.
        (C) The employer shall maintain in effect any job-related 
    protective measures or limitations, other than removal, for as long as 
    a medical determination recommends them to be necessary.
        (ii) End of MRP benefits and return of the employee to former job 
    status.
        (A) The employer may cease providing MRP benefits at the earliest 
    of the following:
        (1) Six months;
        (2) Return of the employee to the employee's former job status 
    following receipt of a medical determination concluding that the 
    employee's exposure to MC no longer will aggravate any cardiac, 
    hepatic, neurological (including stroke), or dermal disease;
        (3) Receipt of a medical determination concluding that the employee 
    can never return to MC exposure.
        (B) For the purposes of this paragraph (j), the requirement that an 
    employer return an employee to the employee's former job status is not 
    intended to expand upon or restrict any rights an employee has or would 
    have had, absent temporary medical removal, to a specific job 
    classification or position under the terms of a collective bargaining 
    agreement.
        (12) Medical Removal Protection Benefits.
        (i) For purposes of this paragraph (j), the term medical removal 
    protection benefits means that, for each removal, an employer must 
    maintain for up to six months the earnings, seniority, and other 
    employment rights and benefits of the employee as though the employee 
    had not been removed from MC exposure or transferred to a comparable 
    job.
    
    [[Page 50731]]
    
        (ii) During the period of time that an employee is removed from 
    exposure to MC, the employer may condition the provision of medical 
    removal protection benefits upon the employee's participation in 
    follow-up medical surveillance made available pursuant to this section.
        (iii) If a removed employee files a workers' compensation claim for 
    a MC-related disability, the employer shall continue the MRP benefits 
    required by this paragraph until either the claim is resolved or the 6-
    month period for payment of MRP benefits has passed, whichever occurs 
    first. To the extent the employee is entitled to indemnity payments for 
    earnings lost during the period of removal, the employer's obligation 
    to provide medical removal protection benefits to the employee shall be 
    reduced by the amount of such indemnity payments.
        (iv) The employer's obligation to provide medical removal 
    protection benefits to a removed employee shall be reduced to the 
    extent that the employee receives compensation for earnings lost during 
    the period of removal from either a publicly or an employer-funded 
    compensation program, or receives income from employment with another 
    employer made possible by virtue of the employee's removal.
        (13) Voluntary Removal or Restriction of an Employee. Where an 
    employer, although not required by this section to do so, removes an 
    employee from exposure to MC or otherwise places any limitation on an 
    employee due to the effects of MC exposure on the employee's medical 
    condition, the employer shall provide medical removal protection 
    benefits to the employee equal to those required by paragraph (j)(12) 
    of this section.
        (14) Multiple Health Care Professional Review Mechanism. 
        (i) If the employer selects the initial physician or licensed 
    health care professional (PLHCP) to conduct any medical examination or 
    consultation provided to an employee under this paragraph (j)(11), the 
    employer shall notify the employee of the right to seek a second 
    medical opinion each time the employer provides the employee with a 
    copy of the written opinion of that PLHCP.
        (ii) If the employee does not agree with the opinion of the 
    employer-selected PLHCP, notifies the employer of that fact, and takes 
    steps to make an appointment with a second PLHCP within 15 days of 
    receiving a copy of the written opinion of the initial PLHCP, the 
    employer shall pay for the PLHCP chosen by the employee to perform at 
    least the following:
        (A) Review any findings, determinations or recommendations of the 
    initial PLHCP; and
        (B) conduct such examinations, consultations, and laboratory tests 
    as the PLHCP deems necessary to facilitate this review.
        (iii) If the findings, determinations or recommendations of the 
    second PLHCP differ from those of the initial PLHCP, then the employer 
    and the employee shall instruct the two health care professionals to 
    resolve the disagreement.
        (iv) If the two health care professionals are unable to resolve 
    their disagreement within 15 days, then those two health care 
    professionals shall jointly designate a PLHCP who is a specialist in 
    the field at issue. The employer shall pay for the specialist to 
    perform at least the following:
        (A) Review the findings, determinations, and recommendations of the 
    first two PLHCPs; and
        (B) Conduct such examinations, consultations, laboratory tests and 
    discussions with the prior PLHCPs as the specialist deems necessary to 
    resolve the disagreements of the prior health care professionals.
        (v) The written opinion of the specialist shall be the definitive 
    medical determination. The employer shall act consistent with the 
    definitive medical determination, unless the employer and employee 
    agree that the written opinion of one of the other two PLHCPs shall be 
    the definitive medical determination.
        (vi) The employer and the employee or authorized employee 
    representative may agree upon the use of any expeditious alternate 
    health care professional determination mechanism in lieu of the 
    multiple health care professional review mechanism provided by this 
    paragraph so long as the alternate mechanism otherwise satisfies the 
    requirements contained in this paragraph.
