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: Direct final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: MSHA is removing 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 amending its regulations 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 also directly informs manufacturers, mine operators, miners, and miners' representatives about which sanitary toilets meet the standard. Removing the application requirements has no substantive effect on the sanitation standards.

DATES: This direct final rule is effective June 20, 2003 without further notice, unless MSHA receives significant adverse comment by May 21, 2003. If MSHA receives such comment, the Agency will publish a timely withdrawal of this direct final rule in the Federal Register.

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.

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 direct final rule to eliminate the need for applications for approval of sanitary toilets and their associated paperwork burden. This direct final rule does 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 remain subject to the provisions of 30 CFR 75.1712-3, which is unchanged.

Direct Final Rule and Significant Adverse Comments

     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 will be ineffective or unacceptable without a change. In determining whether a comment necessitates withdrawal of this direct final rule, MSHA will consider whether it warrants a substantive response in a notice and comment process.
     Elsewhere in this issue of the Federal Register, we are publishing a companion proposed rule under Sec. 553 of the Administrative Procedure Act to speed notice and comment rulemaking should we withdraw this direct final rule. The companion proposed rule and this direct final rule are substantively identical. 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-- C. MSHA and MSHA/NIOSH Approval Criteria

     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 direct final rule's revisions to the existing standards. The direct final rule provides the same level of protection for miners as the existing standards because it guarantees that sanitary toilets meet the same requirements as those which were approved through the existing application process. It has 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 direct final rule eliminates the application for approval requirement and its associated paperwork burden, and provides notice of which types of sanitary toilets may be used by listing them directly in the standard. The direct final rule also requires 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 prohibits the use of privies.
     NIOSH has reviewed this direct final rule and concurs that the application for approval requirements can be removed without reducing protection for miners. NIOSH also agrees that the direct final rule does 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 direct final rule eliminates the application requirement and its associated paperwork burden, and provides notice of which types of sanitary toilets may be used by listing them directly in the standard. The direct final rule also requires 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); prohibits privies and combustion or incinerating toilets underground; and removes 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 direct final rule, and has included its Regulatory Economic Analysis (REA) in this preamble. This direct final rule includes no additional costs for the mining industry and eliminates the costs associated with filing an application for approval. This direct final rule is not 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 direct final rule does 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 direct final 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 direct final 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 direct final 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 past four years is representative of future applications in the absence of this direct final rule. MSHA therefore estimates that, on average, in the absence of the direct final rule, portable toilet manufacturers will file 1.75 applications each year, and mine operators will 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\

---------------------------------------------------------------------------

Compliance Costs
     Cost savings from this direct final rule accrue to sanitary toilet manufacturers and mine operators because they will 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 will be $296 annually. For the mine operator, cost savings will 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) + $1) = $ 2.28].

---------------------------------------------------------------------------

     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 direct final rule eliminates the application process and provides simple compliance information directly to the public, thus eliminating the annual cost burden.

V. Paperwork Reduction Act.

     This direct final rule contains no 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 will no longer be necessary and will be withdrawn.
     This direct final rule will 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 will be 14 burden hours savings annually and associated annual burden costs savings of $294. For the 0.25 mine operators, there will 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 direct final rule removes 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 direct final rule has no 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 direct final rule does 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 direct final rule does not significantly or uniquely affect these entities.

C. Executive Order 12630: Government Actions and Interference With Constitutionally Protected Property Rights

     This direct final rule is not 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 direct final rule will not unduly burden the Federal court system. We wrote the direct final 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 direct final rule and have determined that it has no adverse effects on children.

F. Executive Order 13132: Federalism

     In accordance with Executive Order 13132, we have reviewed this direct final rule and have determined that it does not have ``federalism'' implications.

G. Executive Order 13175: Consultation and Coordination With Indian Tribal Governments
