Opinion for the Court filed by Senior Circuit Judge SWYGERT.
Petitioner United Mine Workers of America (UMWA) seeks review of a decision and order of the Assistant Secretary of Labor for Mine Safety and Health granting Emerald Mines Corporation's (Emerald) petition for modification of a mandatory safety standard at the Emerald No. 1 Mine. Because the Assistant Secretary failed to clearly articulate the test to be applied in evaluating a petition for modification, and because he did not identify the evidence he relied upon in granting Emerald's petition, we vacate the decision and remand.
With the passage of the Federal Mine Health and Safety Act of 1977 (the Act), 30 U.S.C. Secs. 801 et seq., Congress established a highly detailed set of mandatory health and safety standards applicable to underground coal mining. See 30 U.S.C. Secs. 841-878. Congress placed enforcement of the Act with the Secretary of Labor, acting through the Mine Safety and Health Administration (MSHA). 29 U.S.C. Sec. 557a. To provide for changes in technology and mining systems, section 101(a) of the Act allows the Secretary to promulgate improved industry-wide health and safety standards, provided that any such standards do not "reduce the protection" afforded miners by an existing standard. 30 U.S.C. Sec. 811(a)(9). In contrast, section 101(c) permits the Secretary to modify the application of an existing safety standard to a particular mine "if the Secretary determines that an alternative method of achieving the result of such standard exists which will at all times guarantee no less than the same measure of protection afforded the miners of such mine by such standard...." 30 U.S.C. Sec. 811(c). 1 It is the Secretary's authority to grant a mine-specific modification under section 101(c) which is at issue in this case.
On July 29, 1982, Emerald filed a petition with the Secretary seeking modification of the safety standard set forth at 30 C.F.R. Sec. 75.326 2 at its No. 1 Mine. 3 The standard is one of several mandatory safety standards governing mine ventilation. Underground coal mines are ventilated by a set of tunnels or "entries" which continuously move air throughout the mine. At the Emerald No. 1 Mine, the "intake escapeway" is the entry through which fresh air is brought into the mine. It is also the miners' means of escape in the event of an emergency. Air already used to ventilate the mine is removed through the "return entry." The "track entry" is the entry through which miners and materials are hauled in and out of the mine. Finally, the "belt entry" is the tunnel containing the conveyor belts which transport coal from the active working sections of the mine to the surface.
The standard sought to be modified limits the velocity of air permitted in belt entries and prohibits the use of belt entry air to ventilate the underground working areas of the mine. 4 By limiting the air velocity in belt entries, the standard helps prevent the fanning of fires that may originate along belt haulageways. In addition, by prohibiting the use of air to ventilate working places, the standard keeps belt entry contaminants such as coal dust or fire by-products from reaching miners.
In its petition, Emerald proposed to use belt entry air to supplement the ventilation of the active working places of the mine. As an alternative to the protection afforded by the standard, Emerald planned to install a low-level carbon monoxide (CO) detection system in the belt entries. According to Emerald, the CO detection system would provide miners with early warning of a fire in the belt entry before the fire reached a stage where the products of combustion would present a hazard to miners. Because the miners would be alerted in time for them to exit the mine safely, Emerald argued that the proposed modification would provide a measure of protection equal to that of 30 C.F.R. Sec. 75.326.
Following the filing of the petition, MSHA conducted a field investigation pursuant to 30 C.F.R. Sec. 44.13. On June 24, 1983, the Administrator for Coal Mine Safety and Health issued a proposed decision granting Emerald's petition subject to stated conditions. Thereafter, UMWA exercised its right under 30 C.F.R. Sec. 44.14 to request a hearing before a Department of Labor Administrative Law Judge (ALJ) concerning the proposed decision. After the hearing, at which Emerald, MSHA and UMWA participated, the ALJ denied the petition on the ground that Emerald had failed to establish that the proposed alternative would meet the requirements of section 101(c).
Emerald and MSHA subsequently appealed the ALJ's decision to the Assistant Secretary of Labor, as is permitted under 30 C.F.R. Sec. 44.33. On October 3, 1985, the Assistant Secretary reversed the ALJ's decision and granted the petition, subject to certain conditions. 5 In determining whether the modification should be granted under section 101(c), the Assistant Secretary compared the risks associated with the proposed modification with those resulting from the application of the standard at the mine. He concluded that implementing Emerald's proposal would improve the overall safety of the mine in several ways: it would improve ventilation in the belt entry itself by establishing a predictable direction of air flow; it would relieve pressure imbalances at the mine that Emerald argued resulted from compliance with the standard; and it would provide an additional intake airway and escape route to aid evacuation in the event of a fire in the existing intake escapeway. In addition, the Assistant Secretary determined that the proposed air velocity in the belt entry would not contribute to the rapid spread of fire by fanning, that the minimal increases in respirable dust levels would not result in increased health hazards, and that the CO detection system would be a reliable means of providing miners with an early warning of any fire in the belt entry. The Assistant Secretary therefore concluded that Emerald had satisfied the requirements of section 101(c). UMWA subsequently filed a petition for review of the Assistant Secretary's decision pursuant to section 101(d) of the Act, 30 U.S.C. Sec. 811(d).
In reviewing the Assistant Secretary's decision, this court must determine whether the granting of the petition for modification was arbitrary, capricious, an abuse of discretion or otherwise not in accordance with the law. 5 U.S.C. Sec. 706(2)(A). UMWA argues that the Assistant Secretary applied the incorrect legal standard in granting Emerald's petition and that his decision therefore should be set aside. The portion of section 101(c) at issue provides that a petition for modification may be granted if "an alternative method of achieving the result of such standard exists which will at all times guarantee no less than the same measure of protection afforded the miners of such mine by such standard." According to UMWA, the Assistant Secretary erred by failing to require that the proposed alternative both (1) achieve the result of the standard and (2) at all times provide the same measure of protection as the standard. UMWA argues that the "result" portion of the section 101(c) test requires that the alternative provide the same kind of protection as the standard, while the "at...
