[Federal Register: April 21, 2003 (Volume 68, Number 76)] [Proposed Rules] [Page 19477-19482] DEPARTMENT OF LABOR Mine Safety and Health Administration 30 CFR Parts 71 and 75 RIN 1219-AA98 (Phase 9) Standards for Sanitary Toilets in Coal Mines AGENCY: Mine Safety and Health Administration (MSHA), Labor. ACTION: Proposed rule; request for comments. ----------------------------------------------------------------------- SUMMARY: MSHA is proposing to remove an application and approval requirement from existing mandatory standards. Currently, MSHA must approve sanitary toilets for use in underground coal mines, and MSHA and the National Institute for Occupational Safety and Health (NIOSH) must jointly approve sanitary toilets for use in surface coal mines. MSHA and NIOSH base their approval on criteria drawn from the American National Standard Institute's (ANSI's) American National Standard for Sanitation--Nonsewered Waste-Disposal Systems--Minimum Requirements. MSHA is proposing to amend its standards to state which sanitary toilets meet the standard in order to eliminate the need for an application for approval and its associated paperwork burden. This action would also directly inform manufacturers, mine operators, miners, and miners' representatives about which sanitary toilets meet the standard. Removing the application requirements would have no substantive effect on the sanitation standards. DATES: Submit comments by May 21, 2003. ADDRESSES: Clearly identify comments as such and submit them either electronically to zzMSHA-Comments@dol.gov; by facsimile to (202) 693-9441; or by regular mail or hand delivery to MSHA, Office of Standards, Regulations, and Variances, 1100 Wilson Blvd., Room 2313, Arlington, Virginia 22209-3939. Comments are posted for public viewing at http://www.msha.gov/currentcomments.asp. FOR FURTHER INFORMATION CONTACT: Marvin W. Nichols, Director; Office of Standards, Regulations, and Variances, MSHA; Phone: 202-693-9442; FAX: 202-693-9441; E-mail: Nichols-Marvin@dol.gov. SUPPLEMENTARY INFORMATION: I. Introduction. The Office of Management and Budget's (OMB's) current approval for Sec. Sec. 71.500 and 75.1712-6 under control number 1219-0101 expires on November 30, 2003. OMB approval was contingent on MSHA initiating rulemaking ``to update and simplify this standard with the goal of eliminating unnecessary requirements and reducing the unnecessary burdens.'' In response to OMB concerns, MSHA developed this proposed rule to eliminate the need for applications for approval of sanitary toilets and their associated paperwork burden. This proposed rule would not address any other aspect of MSHA's standards for sanitary facilities at coal mines. Sanitary toilet facilities for surface work areas of underground mines would remain subject to the provisions of 30 CFR 75.1712-3, which is unchanged. Proposed Rule, Direct Final Rule, and Significant Adverse Comments Elsewhere in this issue of the Federal Register, we are publishing a direct final rule which is substantively identical to this companion proposed rule. MSHA has determined that this rulemaking is suitable for a direct final rule because we do not expect to receive any significant adverse comments. A significant adverse comment is one that explains (1) why the direct final rule is inappropriate, including challenges to the rule's underlying premise or approach, or (2) why the direct final rule would be ineffective or unacceptable without a change. In determining whether a comment necessitates withdrawal of the direct final rule, MSHA would consider whether it warrants a substantive response in a notice and comment process. We are publishing this companion proposed rule under section 553 of the Administrative Procedure Act to speed notice and comment rulemaking should we withdraw the direct final rule. All interested parties should comment by May 21, 2003 because we will not initiate an additional comment period. II. Background Discussion of Existing Standards A. Regulatory History MSHA originally promulgated sanitation standards under the Federal Coal Mine Health and Safety Act of 1969. The Mining Enforcement and Safety Administration (MESA), MSHA's predecessor, promulgated 30 CFR 75.1712-6 on November 20, 1970 (35 FR 17890) and 30 CFR 71.500 on March 28, 1972 (37 FR 6368). No substantive changes have been made to either provision since that time. Under existing standards, MSHA approves sanitary toilets for installation and use on an industry-wide basis, not on a mine-by-mine basis. MSHA issues three types of approvals: for surface work sites only, for underground work sites only, or for both surface and underground work sites. Once granted, the approval does not expire. Although some of the manufacturers and distributors of approved sanitary toilets are no longer in business, MSHA accepts these approved sanitary toilets as long as they are properly maintained. B. Existing Application for Approval Process The existing standards' requirements for an application for approval of a sanitary toilet can pose an unnecessary burden on manufacturers and mine operators. To effectively evaluate a sanitary toilet for use at a coal mine, MSHA requires that the application for approval contain--
When reviewing the application for approval, MSHA and NIOSH review and evaluate the sanitary features of each toilet for the use intended. Currently, MSHA and NIOSH use portions of the American National Standard Institute's (ANSI's) American National Standard for Sanitation--Nonsewered Waste-Disposal Systems--Minimum Requirements, ANSI Z4.3-1987 (Reaffirmed 1995), as the criteria for evaluating these sanitary features. At a minimum, MSHA and NIOSH use the definitions for the various types of toilets and components of the toilet facility in Section 2; the general requirements for auxiliary features in Sections 3.7, 3.8, and 3.9; and the specific design criteria in Section 7. Exceptions. Although a privy is listed in ANSI Z4.3-1987 (Reaffirmed 1995), MSHA does not approve the use of a privy at any coal mine because sewage could seep through the earth walls and contaminate ground water, earth walls could fail under the harsh conditions at a coal mine, and rain and run-off could flood the privy causing it to overflow and contaminate the mine. MSHA does not approve combustion or incinerating toilets underground because they can create a fire hazard by introducing an ignition source. MSHA does not require a toilet paper holder on unenclosed sanitary toilets underground because it is impractical. D. Types of Approved Sanitary Toilets The following table contains excerpts from ANSI Z4.3-1987 (Reaffirmed 1995) for those types of sanitary toilets that are approved for use in coal mines. MSHA will consider any toilet facility that is one of the types of toilets listed in the Agency's revised standards and meets these same criteria, to be in compliance. ------------------------------------------------------------------------

III. Section-by-Section Discussion The following section-by-section discussion explains the proposed rule's revisions to the existing standards. The proposed rule would provide the same level of protection for miners as the existing standards because it would guarantee that sanitary toilets meet the same requirements as those which were approved through the existing application process. The proposed rule would have no substantive effect on the sanitation standards at coal mines. A. 30 CFR 71.500 for Surface Coal Mines Existing Sec. 71.500 requires all surface coal mine operators to provide at least one approved sanitary toilet at a location convenient to each surface work site and one additional approved sanitary toilet for each 10 miners working at a location. MSHA and NIOSH jointly approve sanitary toilets for use at surface mines. The proposed rule would eliminate the application for approval requirement and its associated paperwork burden, and provide notice of which types of sanitary toilets may be used by listing them directly in the standard. The proposed rule also would require sanitary toilets to have a toilet paper holder with an adequate supply of toilet paper and a toilet seat with a hinged lid, as is required in Section 3 of ANSI Z4.3-1987 (Reaffirmed 1995); and would prohibit the use of privies. NIOSH has reviewed this regulatory action and concurs that the application for approval requirements can be removed without reducing protection for miners. NIOSH also agrees that the regulatory action would not change the criteria for the sanitary toilets. MSHA has incorporated NIOSH's comments in this regulatory action. B. 30 CFR 75.1712-6 for Underground Coal Mines Existing Sec. 75.1712-6 requires all underground coal mine operators to provide and maintain one approved sanitary toilet in a dry location under protected roof within 500 feet of each working place where miners regularly work. Under the existing standard, MSHA must approve sanitary toilets for use at underground locations. The proposed rule would eliminate the application requirement and its associated paperwork burden, and provide notice of which types of sanitary toilets may be used by listing them directly in the standard. The proposed rule also would require sanitary toilets to have a toilet paper holder with an adequate supply of toilet paper and a toilet seat with a hinged lid, as is required in Section 3 of ANSI Z4.3-1987 (Reaffirmed 1995); would prohibit privies and combustion or incinerating toilets underground; and would remove the obsolete December 30, 1970, effective date. IV. The Regulatory Flexibility Act, the Small Business Regulatory Enforcement Fairness Act, and Executive Order 12866 In accordance with Executive Order (E.O.) 12866, MSHA has analyzed the estimated costs and benefits associated with this proposed rule, and has included its Preliminary Regulatory Economic Analysis (PREA) in this preamble. This proposed rule would not include any additional costs for the mining industry and would eliminate the costs associated with filing an application for approval. This proposed rule would not be an economically significant regulatory action under Sec. 3(f)(1) of E.O. 12866. In accordance with Sec. 605 of the Regulatory Flexibility Act (RFA), MSHA certifies that this proposed rule would not have a significant economic impact on a substantial number of small entities. Under the Small Business Regulatory Enforcement Fairness Act (SBREFA) amendments to the RFA, the Agency must include the factual basis for this certification in the proposed rule. Accordingly, the Agency is publishing the factual basis for its regulatory flexibility certification statement in the Federal Register, as part of this preamble, and is providing a copy to the Small Business Administration (SBA), Office of Advocacy. MSHA also will mail a copy of the proposed rule, including the preamble and certification statement, to coal mine operators and miners' representatives and post it on the Agency's Internet Home Page at http://www.msha.gov. Factual Basis for Certification. MSHA is issuing a proposed rule amending 30 CFR parts 71 and 75, concerning applications for approval of sanitary toilets. The Agency is amending its regulations to state which sanitary toilets meet the standard in order to eliminate the need for underground and surface coal mines to file an application for approval and to avoid the associated cost and paperwork burden. Manufacturers are the primary applicants for MSHA or MSHA/NIOSH approval of sanitary toilets. In the last four years, seven manufacturers of portable toilets filed applications to request approval of sanitary toilets. During this same period, only one mine operator filed an application to request approval of sanitary toilets. MSHA expects that the number and distribution of applications over the last four years is representative of future applications in the absence of this proposed rule. MSHA therefore estimates that, on average, in the absence of the proposed rule, portable toilet manufacturers would file 1.75 applications each year, and mine operators would file 0.25 applications each year. Traditionally, MSHA has considered a small mine to be one with fewer than 20 employees. Based on MSHA's definition, the mine operator is considered large because it employs 20 or more workers. The Small Business Administration (SBA) definition for a small business in the mining industry is one with 500 or fewer employees. The mine operator that filed the application is considered a small business by SBA's definition in that it employs fewer than 500 workers. Based on SBA's definition, manufacturers of portable toilets (plastics), NAICS Code 326191 (SIC Code 3088), are defined as small if they have fewer than 500 employees. All of the portable toilet manufacturers are small businesses, according to SBA, because each employs fewer than 500 workers.\1\ --------------------------------------------------------------------------- \1\ Small Business Administration, Small Business Size Standards Matched to North American Industry Classification System (NAICS), Effective July 1, 2002. (http://www.sba.gov/size/sizetable.html). --------------------------------------------------------------------------- Compliance Costs Cost savings from this proposed rule would accrue to sanitary toilet manufacturers and mine operators because they would no longer have to file an application for approval of sanitary toilets. Cost savings from this rule are estimated at $407 annually. The cost savings are based upon the elimination of the filing of an average of 1.75 applications per year by manufacturers and 0.25 applications per year by mine operators. For the manufacturers, cost savings would be $296 annually. For the mine operator, cost savings would be $111 annually. The annual cost savings of $296 for manufacturers is derived in the following manner. On average, a first-line supervisor at a toilet manufacturing facility, earning $20.82 per hour,\2\ takes 8 hours to prepare an application (1.75 applications x 8 hours x $20.82 per hour = $291.48). In addition, a clerical worker, earning $12.66 per hour,\3\ takes 0.1 hour to copy and mail an application (1.75 applications x 0.1 hour x $12.66 per hour = $2.22). Furthermore, MSHA estimates that, on average, each application is two pages long, photocopying costs are $0.15 per page, and postage is $1 [1.75 applications x ((2 pages x $0.15 per page) x $1) = $ 2.28]. --------------------------------------------------------------------------- \2\ U.S. Department of Labor, Bureau of Labor Statistics, Career Guide to Industries--Chemicals Manufacturing, Except Drugs. (http://www.bls.gov/oco/cgs/cgs008.htm ). \3\ U.S. Department of Labor, Bureau of Labor Statistics, Occupational Employment Statistics--2001 National Occupational Employment and Wage Estimates. (http://www.bls.gov/oes/2001/oes433021.htm ). --------------------------------------------------------------------------- The annual cost savings of $111 for the mine operator is derived in the following manner. On average, a mine supervisor, earning $54.92 per hour, takes 8 hours to prepare an application (0.25 application x 8 hours x $54.92 per hour = $109.84). In addition, a clerical worker, earning $19.58 per hour, takes 0.1 hour to copy and mail an application (0.25 application x $0.1 hour x $19.58 per hour = $0.49). Furthermore, MSHA estimates that, on average, each application is two pages long, photocopying costs are $0.15 per page, and postage is $1 [0.25 application x ((2 pages x $0.15 per page) + $1) = $0.33]. This proposed rule would eliminate the application process and provide simple compliance information directly to the public, thus eliminating the annual cost burden. V. Paperwork Reduction Act This proposed rule would not contain any additional information collections subject to review by the Office of Management and Budget (OMB) under the Paperwork Reduction Act. Consequently, the information collection currently approved by OMB under control number 1219-0101 would no longer be necessary and would be withdrawn. This proposed rule would result in 16 annual burden hour savings and associated annual burden cost savings of $404 related to elimination of 2 applications annually for sanitary toilets. Of this total, for the 1.75 portable toilet manufacturers, there would be 14 burden hours savings annually and associated annual burden costs savings of $294. For the 0.25 mine operators, there would be 2 burden hours savings annually and associated annual burden cost savings of $110. The annual reduction of 14 burden hours and the $294 annual burden costs savings for the 1.75 portable sanitary toilet manufacturers are derived in the following manner. On average, a first-line supervisor at a toilet manufacturing facility, takes 8 hours to prepare an application (1.75 applications x 8 hours = 14 hours). In addition, a clerical worker takes 0.1 hour (or 6 minutes) to copy and mail an application (1.75 applications x 0.1 hour = 0.18 hours). The hourly wage rate for a first-line supervisor at a portable toilet manufacturing facility is $20.82 ($20.82 x 14 burden hours = $291.48). The hourly wage rate for a clerical worker (billing and posting clerks) is $12.66 ($12.66 x 0.18 burden hours = $2.28). The annual reduction of 2 burden hours and the $110 annual burden costs savings for the 0.25 mines are derived in the following manner. On average, a mine supervisor takes 8 hours to prepare an application (0.25 applications x 8 hours = 2 hours). In addition, a clerical worker takes 0.1 hour (or 6 minutes) to copy and mail an application (0.25 applications x 0.1 hour = 0.03 hour). The hourly wage rate for a mine supervisor is $54.92 ($54.92 x 2 hours = $109.84). The hourly wage rate for a clerical worker is $19.58 ($19.58 x 0.03 hours = $0.58). This proposed rule would remove this burden by eliminating the application process and providing information directly to the public. VI. Other Regulatory Considerations A. The National Environmental Policy Act of 1969 The National Environmental Policy Act (NEPA) (42 U.S.C. 4321 et seq.) requires each Federal agency to consider the environmental effects of its actions. This proposed rule would have no adverse environmental impact because it has no substantive effect on the existing standards. B. Unfunded Mandates Reform Act of 1995 We have determined, for purposes of Sec. 202 of the Unfunded Mandates Reform Act of 1995, that this proposed rule would not include any Federal mandate that may result in increased expenditures by state, local, or tribal governments in the aggregate of more than $100 million, or increased expenditures by the private sector of more than $100 million. We also determined, for purposes of Sec. 203, that this proposed rule would not significantly or uniquely affect these entities. C. Executive Order 12630: Government Actions and Interference With Constitutionally Protected Property Rights This proposed rule would not be subject to Executive Order 12630 because it would not involve implementation of a policy with ``takings'' implications. D. Executive Order 12988: Civil Justice Reform In accordance with Executive Order 12988, we have determined that this proposed rule would not unduly burden the Federal court system. We wrote the proposed rule to provide a clear legal standard for affected conduct and have reviewed it to eliminate drafting errors and ambiguities. E. Executive Order 13045: Protection of Children From Environmental Health Risks and Safety Risks In accordance with Executive Order 13045, we have evaluated the environmental health and safety effects of this proposed rule and have determined that it would have no adverse effects on children. F. Executive Order 13132: Federalism In accordance with Executive Order 13132, we have reviewed this proposed rule and have determined that it would not have ``federalism'' implications. G. Executive Order 13175: Consultation and Coordination with Indian Tribal Governments In accordance with Executive Order 13175, we certify that this proposed rule would not impose substantial direct compliance costs on Indian tribal governments. H. Executive Order 13211: Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use In accordance with Executive Order 13211, we have reviewed this proposed rule and have determined that it would have no effect on the production or price of coal. Consequently, it would have no significant adverse effect on the supply, distribution, or use of energy, and no reasonable alternatives to this action would be necessary. I. Executive Order 13272: Proper Consideration of Small Entities in Agency Rulemaking In accordance with Executive Order 13272, MSHA has thoroughly reviewed the proposed rule to assess and take appropriate account of its potential impact on small businesses, small governmental jurisdictions, and small organizations. As discussed previously in this preamble, MSHA has determined that the proposed rule would not have a significant economic impact on a substantial number of small entities.
