I.D. No. 11-02664                                                                 Docket No. M-2017-024-C


On November 6, 2017, ICG Illinois, LLC filed a petition seeking a modification of the application of 30 C.F.R. § 75.500(d) to its Viper Mine in Sangamon Count y, Illinois.

The petitioned standard, 30 C.F.R. § 75.500(d) states,

(d) All other electric face equipment which is taken into or used inby the last crosscut of any coal mine, except a coal mine referred to in §75.501, which has not been classified under any provision of law as a gassy mine prior to March 30, 1970, shall be permissible.

Petitioner is requesting a modification of the standard to allow the use of certain nonpermissible low-voltage or battery-powered electronic testing and diagnostic equipment to be taken or used inby the last open crosscut with additional safeguards including the following: MSHA inspection of equipment before initial use, subsequent pre-use safety checks of equipment by a qualified person, cessation of coal production during use, continuous methane monitoring before and during equipment use, a prohibition on using equipment when methane is at or above 1% or when float coal dust is in suspension, and training with respect to safe use, hazards and limitations of the equipment. The petitioner contends that this alternative method will at all times guarantee no less than the same measure of protection afforded by the standard.

MSHA investigators conducted an investigation into the merits of the petition and filed a report of their findings with the Administrator for Coal Mine Safety and Health. After careful review of the entire record, including the petition and MSHA's investigative report, this Proposed Decision and Order is issued.

Findin gs of Fact and Conclusions of Law

MSHA investigators conducted an investigation of ICG Illinois, LLC's Viper Mine on August 9, 2018.

The Viper Mine is located near Williamsville in Sangamon County, Illinois. This underground mine began production in 1982 operating in the Springfield No. 5 coal seam. The mine operates one fishtail and two single-split ventilated production units at present. The four MMU's on these three production units utilize Joy continuous miners and DBT battery ram cars to extract the coal and deliver the coal to the belt tail. It is transported via belt conveyors through the mine and out of the mine, via the slope.
There is an intake air shaft, return air shaft (equipped with an exhausting fan), and a divided slope (belt in upper compartment and men and material traveling in the lower compartment). Daily production averages approximately 11,000 tons per day from three production shifts. The mine liberates 687,360 cfm of methane in 24 hours.

There are currently 270 employees at the mine. Three management employees were interviewed and two hourly miners. Denny Alderman is the Compliance Manager and also the miners' representative. All were aware of the Petition and its contents and were in favor of it being granted.

The granting of this petition would affect all underground miners at the mine.

Petitioner requests that the following testing and diagnostic equipment be taken or used inby the last open crosscut: Laptop computers; oscilloscopes; vibration analysis machines; cable fault detectors; point temperature probes; infrared temperature devices; insulation testers (meggers); voltage, current, resistance, and power measurement devices; ultrasonic thickness gauges; electronic component testers; and electronic tachometers. Other testing and diagnostic equipment may be used if approved in advance by the MSHA District Manager.

The petitioner would also like to use other testing and diagnostic equipment approved in advance by MSHA's District Manager. The petitioner may use more than one piece of this equipment at a time when performing testing and diagnostic tasks. The petitioner's request describes the subject equipment in general terms, such as type and functionality, but does not include the equipment make, model, certification, intended use, or equipment rating according to hazardous locations.

MSHA already has approved some of the above-listed equipment as permissible. MSHA's Approval and Certification Center List of Approved Products contains permissible electronic testing and diagnostic equipment, including some of the equipment the petitioner has requested to use. For example, the petitioner requested to use vibration analysis machines, point temperature and infrared temperature devices, and voltage, current and resistance meters, which currently are on the list of approved products. This Proposed Decision and Order excludes already-approved equipment.

Other equipment that the petitioner requested to use is not MSHA-approved as permissible. MSHA notes that National Institute of Occupational Safety and Health

(NIOSH) researchers have conducted studies on intrinsically safe (IS) equipment and believe that that International Electrotechnical Commission (IEC) document 60079-11, or the American National Standards Institute (ANSI)/International Society (ISA) document 60079-11 for two-fault equipment (marked as ia), would provide an equivalent level of safety as MSHA-approved equipment.1 MSHA does not consider all equipment that meets the 60079-11 standard as equivalent to MSHA approval at this time. However, MSHA also recognizes that use of equipment meeting the 60079-11 standard for two-fault equipment (and even, to a lesser extent, equipment meeting onefault (marked as ib) or no-fault (marked as ic) standards) provides a level of safety that is not provided by equipment that does not meet the IEC/ ANSI/ISA standards.

The safety purpose of 30 C.F.R. § 75.500(d) is to ensure that electric equipment will not cause a mine ignition, fire, or explosion when taken or used inby the last open crosscut. Similarly, the petitioner's alternative proposal seeks to ensure that, when used, nonpermissible testing and diagnostic equipment will not introduce an ignition, fire, or explosion hazard by limiting such use to situations in which coal production has ceased during use, methane levels are at or below 1 %, no float coal dust is in suspension, as well as with increased equipment checks, methane monitoring, and training. However, while these conditions would mitigate the risks of a mine ignition, fire, or explosion when taken or used inby the last open crosscut, MSHA has determined that additional conditions and clarifications are necessary to achieve the same measure of protection as using permissible testing and diagnostic equipment, including specifications for the use of lithium batteries, using equipment that meets IEC/ ANSI/ISA standards, retiring older equipment, and more prescriptive checking, recordkeeping and training requirements.

Underground miners at the Viper Mine are not represented by a labor organization, and there are no Representative of Miners at the mine. The Investigator verified that a copy of the proposed petition for modification was posted on the mine1s bulletin board.
MSHA also interviewed miners as part of its investigation, and they did not raise safety concerns related to the use of this equipment.

MSHA finds that the alternate method proposed by the Petitioner (and as amended herein by MSHA) will at all times guarantee no less than the same measure of protection afforded the miners under 30 C.F.R. § 75.500(d).


Wherefore, pursuant to the authority delegated by the Secretary of Labor to the Administrator for Coal Mine Safety and Health and pursuant to Section 101 (c) of the Federal Mine Safety and Health Act of 1977, as amended, 30 U.S.C. § 811 (c), it is ordered that ICG Illinois, LLC's Petition for Modification of the application of 30 C.F.R.§ 75.500(d) in the Viper Mine is hereby:

GRANTED, for low-voltage or battery-powered non-permissible electronic testing and diagnostic equipment when taken or used inby the last open crosscut (subject area), conditioned upon compliance with the following terms and conditions:

1. This equipment shall be used only: (1) until MSHA-approved permissible electronic testing and diagnostic equipment is available; (2) if mechanical equipment is not commercially available that can perform the work; or (3) when the mining equipment being tested cannot be towed or moved under its own power to intake air, out of the subject area. The equipment allowed under this Order (low voltage or battery-powered non-permissible electronic testing and diagnostic equipment) shall be limited to: laptop computers; oscilloscopes; insulation testers (meggers); signal analyzer devices; ultrasonic measuring devices; electronic component testers; and electronic tachometers for testing or troubleshooting mining equipment. Where commercially available, the operator must use equipment that meets IEC 60079-11 or the ANSI/UL 60079-11 for two-fault IS (marked ia), one-fault IS (marked ib), or no-fault IS (marked ic) in that order of preference. The equipment must have an IP 66 rating or higher when available. When an IP 66 rating is not available, the highest IP rating available must be used. When equipment contains lithium batteries, the equipment must meet lithium battery safety standard UL1642 or IEC 62133. All other equipment in the subject area must be permissible.

2. A record for this equipment shall be maintained on mine property either in a secure book or electronically in a secure computer system not susceptible to alteration. The record will contain the date of manufacture and/ or purchase of each particular piece of electronic testing and diagnostic equipment and include proof of compliance with any lithium battery safety standard. The original equipment manufacturers' user and maintenance manuals also shall be maintained on mine property.

The record and manuals shall be made available to Authorized Representatives of the Secretary and miners at the mine.

3. The equipment to be used in the subject area shall be examined by a qualified person, as set forth in 30 C.F.R. § 75.153, prior to taking the equipment underground to ensure the equipment is being maintained in a safe operating condition. At a minimum, the qualified person conducting the exam shall:

i. Check the instrument for any physical damage and the integrity of the case;
ii. Remove the battery and inspect for corrosion;
iii. Inspect the contact points to ensure a secure connection to the battery;
iv. Reinsert the battery and power up and shut down to ensure proper connections;
v. Check the battery compartment cover or battery attachment to ensure that it is securely fastened; and
vi. For equipment utilizing lithium type cells, ensure the lithium cells and/ or pack are not damaged or swelled in size.

The results of these examinations shall be recorded.

When 1.0 percent or more of methane is detected while the equipment is being used, the equipment shall be de-energized immediately and withdrawn out of the subject area to fresh air. Batteries shall not be removed to deenergize equipment because removing the battery exposes battery contacts to accidental short-circuiting. All requirements of 30 C.F.R. § 75.323 must be met before returning the equipment to the subject area.

8. For additional safety, prior to taking the equipment to the subject area or energizing the equipment in the subject area, a certified person (as set forth by 30 C.F.R.§ 75.100) shall conduct a visual examination of the location where the equipment will be used for: 1) evidence that the subject area appears to be sufficiently rock-dusted and;

2) the presence of accumulated combustible material including float coal dust in suspension. If the rock-dusting appears insufficient, or the presence of float coal dust is observed in suspension, the equipment may not be energized until sufficient rock dust has been applied and/ or the accumulations of combustible materials including float coal dust in suspension have been cleaned-up or removed.

9. All hand-held methane detectors shall be MSHA-approved and maintained in permissible and proper operating condition as set forth by 30 C.F.R. § 75.320. Measurement devices shall be calibrated or bump tested before each shift to verify proper operation. In addition, all methane detectors must provide visual and audible warnings when methane is detected at and above 1.0 percent.

10. Prior to energizing the equipment in the subject area, methane tests must be made at least 12 inches from the roof, face, ribs and floor, as set forth in 30 C.F.R. § 75.323(a).

11. The subject area must be examined preshift, as set forth by 30 C.F.R. § 75.360, prior to using the equipment. If the area was not examined preshift, a supplemental examination, as set forth by 30 C.F.R. § 75 .361, must be performed before any noncertified person enters the area.

12. Before using the equipment in the subject area, the qualified person must confirm by measurement or by inquiry of the certified person in charge of the section, that the air quantity on the section, for that shift, is at least the minimum quantity required by the mine's approved ventilation plan.
Two qualified persons shall continuously monitor for methane immediately before and during the use of the equipment in the subject area. Each qualified person shall have a hand-held methane detector (one person must use a catalytic detector and the other person must use an infrared gas detector) and be strategically positioned in locations with the greatest potential to detect hazardous gas in the area where the equipment is being used. A qualified person shall also remain with the equipment while the equipment is used in the subject area.

13. Batteries contained in the equipment must be "changed out" in intake air, out of the subject area.
