I. Introduction
The final rule requires mine operators to install proximity
detection systems on continuous mining machines, except full-face
continuous mining machines, in underground coal mines according to a
phase-in schedule for newly manufactured and in-service equipment. A
proximity detection system consists of machine-mounted components and
any miner-wearable components. For proximity detection systems with
miner-wearable components, the mine operator must provide a miner-
wearable component to be worn by each miner on the working section
(including producing or maintenance shifts). The final rule establishes
performance and maintenance requirements for proximity detection
systems and requires training for persons performing the installation
and maintenance. These requirements will strengthen protections for
miners by reducing the potential for pinning, crushing, or striking
accidents that result in fatalities and injuries to miners who work
near continuous mining machines.
A. Regulatory Authority
This final rule is issued under section 101 of the Federal Mine
Safety and Health Act of 1977 (Mine Act), as amended.
B. Background
Proximity detection is a technology that uses electronic sensors to
detect motion or the location of one object relative to another.
Proximity detection systems can provide a warning and stop mining
machines before a pinning, crushing, or striking accident occurs that
could result in injury or death to a miner. Miners are exposed to
hazards from working near continuous mining machines in the confined
space of an underground coal mine. Conditions in underground coal mines
that contribute to these hazards include limited visibility, limited
space around continuous mining machines, and uneven and slippery ground
conditions that may contain loose rock or other debris.
[[Page 2189]]
To assess the costs and benefits of the final rule, MSHA conducted
a review of fatal and nonfatal pinning, crushing, and striking
accidents, which occurred in underground coal mines from 1984 through
2013, to identify those that could have been prevented by using a
proximity detection system. Of the 75 preventable fatalities resulting
from pinning, crushing, and striking accidents, 34 were associated with
continuous mining machines. During this same time period, MSHA
estimates that the use of a proximity detection system could have
prevented approximately 238 nonfatal injuries associated with
continuous mining machines, excluding full-face continuous mining
machines. From 2010 through 2013, six underground coal miners working
in close proximity to continuous mining machines died from pinning,
crushing, or striking accidents.
These accidents continue to occur. In February 2014, a miner was
fatally crushed by a continuous mining machine. Proximity detection
systems are needed because training and outreach initiatives alone,
while helpful, have not prevented these accidents from continuing to
occur. These accidents are preventable and the proximity detection
systems can provide necessary protections for miners.
There are four proximity detection systems approved under the
existing regulations for permissibility in 30 CFR part 18. These
approvals are intended to ensure that the systems will not introduce an
ignition hazard when operated in potentially explosive atmospheres.
MSHA's approval regulations in 30 CFR part 18 do not address how
systems will perform in reducing pinning, crushing, or striking
hazards.
MSHA estimates that approximately 438 of the 863 continuous mining
machines in underground coal mines are not currently equipped with
proximity detection systems. MSHA monitors the installation and
development of proximity detection systems to maintain information on
the number of proximity detection systems in use and the capabilities
of the various systems. As of January 2015, 425 continuous mining
machines were equipped with proximity detection systems and are being
used in underground coal mines. MSHA believes the majority of these
systems will meet the provisions of this final rule without much
change. For example, continuous mining machines equipped with proximity
detection systems may only need modification of the warning signals to
meet the requirements in this final rule.
For those continuous mining machines not equipped with a proximity
detection system, the phase-in schedule provides time for mine
operators to schedule installation of proximity detection systems
during planned rebuilds. MSHA anticipates that mine operators will
equip continuous mining machines with proximity detection systems
during the first planned rebuild that occurs prior to March 16, 2018.
MSHA published a Request for Information (RFI) on proximity
detection systems in the Federal Register on February 1, 2010 (75 FR
5009) and a proposed rule on August 31, 2011 (76 FR 54163). The Agency
held four public hearings. The comment period closed November 28, 2011.
MSHA received comments from miners, mining associations, mining
companies, manufacturers, and a federal government agency. Comments
related to provisions of the final rule are addressed in the following
section-by-section analysis.
II. Section-by-Section Analysis
A. Sec. 75.1732(a) Machines Covered
Final Sec. 75.1732(a) requires operators to equip continuous
mining machines, except full-face continuous mining machines, with
proximity detection systems according to a phase-in schedule. For
proximity detection systems with miner-wearable components, the mine
operator must provide a miner-wearable component to be worn by each
miner on the working section. Together, the machine-mounted components
and any miner-wearable components make up the overall proximity
detection system.
Most commenters supported the use of proximity detection technology
and stated that proximity detection systems are available for use on
continuous mining machines. Some commenters, however, stated that MSHA
should not require proximity detection systems until MSHA can assure
that systems are safe and effective. A commenter stated that no
proximity detection system has proven to be reliable and effective
enough in an underground coal mine to be used as a safety device.
Proximity detection systems are available and are in use with
continuous mining machines. MSHA has determined that working near
continuous mining machines in underground coal mines exposes miners to
dangers that have resulted in preventable injuries and fatalities.
MSHA's experience with testing and demonstration of the four available
systems shows that they are sufficiently developed to be used with
continuous mining machines and perform effectively.
Final Sec. 75.1732(a), like the proposal, requires proximity
detection systems to be installed on continuous mining machines, which
include both on-board operated and remote-controlled continuous mining
machines, except for full-face continuous mining machines.
A full-face continuous mining machine includes integral roof
bolting equipment and develops the full width of the mine entry in a
single cut, generally without having to change its location.
Some commenters stated that persons working around full-face
continuous mining machines should be required to use a proximity
detection system for tramming because tramming a full-face continuous
mining machine can put miners at risk. One commenter stated that
proximity detection systems are not needed on full-face continuous
mining machines because they are much larger and slower than place-
changing continuous mining machines and there are few, if any, crushing
injuries caused by normal movement. Other commenters stated that the
final rule should also require the use of proximity detection systems
on shuttle cars, loading machines, scoops, bolters, and other
equipment.
After considering comments, the final rule, like the proposal, does
not require mine operators to equip full-face continuous mining
machines with proximity detection systems. The Agency has not found any
history of accidents involving full-face continuous mining machines and
there is limited experience with proximity detection systems on these
machines.
The final rule does not require that operators equip other mobile
machines with proximity detection systems. MSHA is addressing the use
of proximity detection systems on other mobile machines in a separate
rulemaking (RIN 1219-AB78).
Final Sec. 75.1732(a), unlike the proposal, requires that, for
proximity detection systems with miner-wearable components, the mine
operator must provide a miner-wearable component to be worn by each
miner on the working section.
In the proposal, MSHA solicited comments on which miners working
around continuous mining machines should be required to have a miner-
wearable component. In the preamble to the proposal, MSHA noted that
the cost estimates for the miner-wearable components included in the
Preliminary
[[Page 2190]]
Regulatory Economic Analysis (PREA) were based on miners on the working
section being equipped with these components. MSHA estimated that, on
average, there are seven miners on the working section and they would
be provided with miner-wearable components.
Several commenters stated that any miner on the working section
should be required to wear a miner-wearable component. One commenter
stated that only miners who interact closely with the continuous mining
machine on a daily basis should wear a miner-wearable component. This
commenter noted that only the continuous mining machine operator,
helper/cable handler, and maintenance personnel working on an energized
continuous mining machine were fatally injured in the pinning,
crushing, and striking accidents involving continuous mining machines.
Each of the four proximity detection systems approved for
underground coal mines in the United States uses a miner-wearable
component to determine distance between the machine and a miner. These
systems cannot detect a miner who is not wearing the component and,
therefore, could not stop the machine before contacting such miners.
After considering the comments, MSHA determined that all miners on
a working section where the continuous mining machine is equipped with
a proximity detection system must wear a miner-wearable component.
Under the final rule, the mine operator must provide a miner-wearable
component to be worn by each miner on the working section (including
production and maintenance shifts).
In MSHA's experience, most operators who move continuous mining
machines outby the working section generally use miners from the
working section who would be protected by the proximity detection
system. MSHA anticipates that this industry practice would continue
after the final rule goes into effect.
A commenter stated that some proximity detection systems have
limited ability to function properly with more than two miner-wearable
components. MSHA has observed two proximity detection systems
functioning properly with multiple miner-wearable components in use on
the working section, demonstrating that proximity detection systems can
function properly with more than two miner-wearable components. MSHA is
aware that, in the past, a system has experienced some adverse effects
when two or more miner-wearable components were near the machine. The
adverse effects were unintended expansion of the warning and stop
distances, but these effects would not prevent the system from meeting
the requirements of the final rule (e.g., to stop before contacting a
miner). MSHA has found that advances in the technology now allow
proximity detection systems to function properly with more than two
miners on the working section without any adverse effects.
MSHA proposed a phase-in schedule of 3 months for continuous mining
machines (except full-face continuous mining machines) manufactured
after the publication date of a final rule and 18 months for machines
(except full-face continuous mining machines) manufactured on or before
the publication date of a final rule. Although not separately discussed
under the proposal, machines equipped with a proximity detection system
prior to the publication date of a final rule would have been subject
to the 18-month phase-in schedule for continuous mining machines
manufactured before the publication date.
Final Sec. 75.1732(a)(1) requires continuous mining machines
manufactured after March 16, 2015 to meet the requirements in this
section no later than November 16, 2015. These machines must meet the
requirements in this section when placed in service with a proximity
detection system.
Final Sec. 75.1732(a)(2) requires continuous mining machines
manufactured and equipped with a proximity detection system on or
before March 16, 2015 to meet the requirements in this section no later
than September 16, 2016.
Final Sec. 75.1732(a)(3) requires continuous mining machines
manufactured and not equipped with a proximity detection system on or
before March 16, 2015 to meet the requirements in this section no later
than March 16, 2018. These machines must meet the requirements in this
section when placed in service with a proximity detection system. A
continuous mining machine is placed in service when it is equipped with
a proximity detection system and placed in the underground coal mine.
MSHA solicited comments on the proposed phase-in schedule of 3
months for new machines and 18 months for in-service machines.
One commenter supported the proposed phase-in schedule of 3 months
for new machines. Several commenters stated additional time is needed
for new machines and suggested 6 months. A commenter stated that
additional time was needed to develop manuals, train miners, and
validate installations. Some commenters also stated that the proposed
schedule was not sufficient to allow for the required MSHA approvals.
One commenter supported the proposed phase-in schedule of 18 months
for machines manufactured before the effective date of the rule. Many
commenters stated that the proposed phase-in schedule was insufficient
to provide for installation of proximity detection systems on
continuous mining machines. These commenters stated that additional
time is necessary to allow mine operators to equip continuous mining
machines manufactured before the effective date of the rule with
proximity detection systems during scheduled rebuilds. Most commenters
stated that retrofitting these machines on the surface is necessary to
assure the quality of the installations. One commenter, however, has
experience installing proximity detection systems underground and on
the surface and provided estimated timeframes for installation
underground, on the surface of a mine, and at the manufacturer or
rebuild facility. Commenters generally recommended a 36-month timeframe
before requiring installation for in-service machines. Some commenters
suggested 24 months, while others suggested 48 months. MSHA agrees that
it will take more time than proposed for proximity detection system
manufacturers, machine manufacturers, and mine operators to obtain
approval under 30 CFR part 18, and for manufacturers to produce and
mine operators to install proximity detection systems.
MSHA has determined that the longer phase-in schedules in the final
rule provide an appropriate amount of time for operators to engage in
the necessary actions to comply with the final rule. This is based on
the availability of four MSHA-approved proximity detection systems for
continuous mining machines, the estimated number of continuous mining
machines that would be replaced by newly manufactured machines during
the phase-in period, manufacturers' capacity to produce and install
proximity detection systems on machines in use, and comments received
in response to the proposed rule. The compliance dates provide time for
manufacturers to produce and install proximity detection systems, for
mine operators to modify their existing proximity detection systems,
and for mine operators to train their workforce.
MSHA considers the date of manufacture as the date identified on
the machine or otherwise provided by the manufacturer. MSHA considers a
[[Page 2191]]
continuous mining machine to be equipped with a proximity detection
system when the machine-mounted components are installed on the machine
and miners are provided with the miner-wearable components.
Mine operators that obtain continuous mining machines manufactured
after March 16, 2015 must comply no later than November 16, 2015. MSHA
believes that these machines can be equipped with proximity detection
systems during the manufacturing process. This compliance date provides
time for manufacturers and mine operators to modify any MSHA approvals,
if necessary; provide miners with miner-wearable components; and
provide training to meet the requirements of this final rule.
Continuous mining machines manufactured and equipped with the machine-
mounted components of a proximity detection system after March 16, 2015
must meet the requirements of the final rule when placed in service.
MSHA believes it is important for continuous mining machines equipped
with a proximity detection system to meet the final rule's requirements
when placed in service to assure that miners are protected from
pinning, crushing, and striking hazards.
As stated earlier, under the proposal, continuous mining machines
in use in underground coal mines and equipped with proximity detection
systems prior to the publication date of a final rule would have been
subject to the proposed 18-month phase-in schedule for continuous
mining machines manufactured before the publication date. A phase-in
schedule for this group of machines was not discussed separately in the
proposal, as there were a limited number of continuous mining machines
equipped with proximity detection systems in service in the United
States when the proposal was published. However, as of January 2015,
MSHA estimates that 425 continuous mining machines in use in
underground coal mines were equipped with proximity detection systems.
This final rule provides 18 months after March 16, 2015 for mine
operators to make modifications to the existing proximity detection
systems on these machines. MSHA has determined that 18 months provides
operators with enough time to obtain any MSHA approvals, to modify
continuous mining machines that are equipped with a proximity detection
system to meet the requirements, and to provide training. MSHA believes
the majority of these machines will comply with the provisions of this
final rule without much change to the systems. For example, continuous
mining machines equipped with proximity detection systems may only need
modification of the warning signals to meet the requirements of this
final rule. MSHA expects that the systems can be modified during
maintenance shifts while the machine is underground.
Most continuous mining machines equipped with proximity detection
systems are operating with one miner-wearable component. This component
is for the machine operator. To meet the requirements of the final
rule, mine operators will need to provide miner-wearable components to
additional miners on the working section.
MSHA proposed an 18-month phase-in schedule for machines
manufactured before the publication date of the final rule. MSHA has
determined that allowing up to 36 months after March 16, 2015 provides
both operators and manufacturers with enough time to retrofit the
continuous mining machines manufactured on or before March 16, 2015.
MSHA recognizes that machines that are in use when the final rule goes
into effect will need to be taken out of use for a period of time. The
longer phase-in schedule under the final rule provides mine operators
time to complete the installation during planned rebuilds or scheduled
maintenance and provides time to train the workforce on proximity
detection systems. MSHA anticipates that mine operators will equip
continuous mining machines with proximity detection systems during the
first planned rebuild that occurs prior to March 16, 2018.
Once these continuous mining machines are retrofitted with a
proximity detection system, mine operators must meet the requirements
of the final rule when these machines are placed in service to assure
that miners are protected from pinning, crushing, and striking hazards.
MSHA acknowledges that it will take some time for operators and
manufacturers to obtain MSHA approvals to equip continuous mining
machines with proximity detection systems. MSHA must approve miner-
wearable components and continuous mining machines with machine-mounted
components of a proximity detection system as permissible equipment
under existing regulations in 30 CFR part 18. The three methods to
obtain MSHA approval to add the machine-mounted components of a
proximity detection system to a continuous mining machine are: (1) A
continuous mining machine manufacturer can apply for a Revised Approval
Modification Program (RAMP) approval; (2) a mine operator can apply to
the Approval and Certification Center (A&CC) for a field modification;
or (3) a mine operator can notify the MSHA district manager through a
district field change application.
MSHA offers an optional Proximity Detection Acceptance (PDA)
program which allows a proximity detection system manufacturer to
obtain MSHA acceptance for the machine-mounted components of a
proximity detection system (PDA Acceptance Number). This acceptance
states that the machine-mounted components of the proximity detection
system have been evaluated under 30 CFR part 18 and are suitable for
installation on an MSHA-approved machine. It permits the manufacturer
or owner of a machine to add the machine-mounted components of a
proximity detection system to a machine by requesting MSHA approval to
add the acceptance number to the machine approval. MSHA believes the
phase-in schedule in the final rule provides the time needed to obtain
MSHA approval or acceptance.
The phase-in schedule under the final rule also allows time for the
mine operators to train miners on how to use proximity detection
systems. Mine operators, under existing 30 CFR part 48, must provide
miners with new task training. MSHA intends that mine operators will
address safety issues, such as some machines being equipped with
proximity detection systems while others are not, that might arise
during the phase-in period.
Some commenters stated that the final rule should not include
additional or redundant training requirements. One commenter stated
that initial training (new task training) and retraining should be
separate from 30 CFR part 48 annual retraining requirements. This
commenter also stated that retraining on proximity detection systems
should be performed at least quarterly.
Commenters stated that training should include a combination of
classroom and hands-on training and that MSHA should consider a cold-
start period (i.e., using a proximity detection system without an
active stop function) to allow miners to become familiar with how
proximity detection systems function. A commenter stated that, during a
cold-start period, the stopping function is not yet active, which
facilitates employee interpretation and exploration of the system and
identification of possible variations to normal safe operating
procedures. Commenters stated that training should be provided to all
miners who may come in contact with a continuous mining machine.
[[Page 2192]]
Miners working near continuous mining machines equipped with
proximity detection systems will engage in different and unfamiliar
machine operating procedures resulting from new work positions, machine
movements, and new visual and audible signals. Training on proximity
detection systems, other than for installing and maintaining systems,
is required under existing 30 CFR part 48. Existing Sec. 48.7(a)
requires that miners assigned to new work tasks as mobile equipment
operators not perform new work tasks until training has been completed.
In addition, Sec. 48.7(c) requires that miners assigned a new task not
covered in Sec. 48.7(a) be instructed in the safety and health aspects
and safe work procedures of the task prior to performing the task.
Miners working near continuous mining machines equipped with proximity
detection systems will receive new task training on the operation of
the newly equipped machine and the miner-wearable components. New task
training could include: General proximity detection system operation
during tramming, cutting, and loading; warning and stop zone size and
shape; response to warning signals; response to system malfunction; and
re-charging miner-wearable components.
New task training is separate from new miner training under
existing Sec. 48.5 and annual refresher training under existing Sec.
48.8. New task training helps assure that miners have the necessary
skills to perform new tasks prior to assuming responsibility for these
tasks. Mine operators should assure that training on proximity
detection systems includes hands-on training during supervised non-
production activities. The hands-on training allows miners to
experience how the systems work and to determine the appropriate work
locations. Based on Agency experience, hands-on training is most
effective when provided in miners' work locations. As required by
existing Sec. 48.7(a)(3), machine operators must be instructed in safe
operating procedures applicable to new or modified machines to be
installed or put into operation in the mine, which require new or
different operating procedures.
New task training cannot include cold-start training underground
after the relevant compliance date because the system must meet the
requirements of the final rule at that time (e.g., stop the machine
before contacting a miner, provide audible and visual warning signals).
B. Sec. 75.1732(b) Requirements for a Proximity Detection System
Final Sec. 75.1732(b) establishes requirements for proximity
detection systems. A proximity detection system includes machine-
mounted components and miner-wearable components.
Final Sec. 75.1732(b)(1) requires that a proximity detection
system cause a machine, which is tramming from place-to-place or
repositioning, to stop before contacting a miner except for a miner who
is in the on-board operator's compartment. This provision is changed
from proposed Sec. 75.1732(b)(1) that would have required that a
proximity detection system cause a machine to stop no closer than 3
feet from a miner.
MSHA solicited comments on the proposed 3-foot stopping distance
and on alternatives such as other specific stopping distances or a
performance-based requirement. Performance-based requirements focus on
attaining objectives, such as stopping a machine before contacting a
miner, rather than being prescriptive in how the result is achieved,
such as stopping within a certain distance. Some commenters stated that
the Agency's proposal to require the machine to stop no closer than 3
feet from a miner would not provide flexibility to allow for mine- and
machine-specific conditions. They stated that there were too many
variables to be able to assure that the machine will stop consistently
before getting to 3 feet from a miner. According to these commenters,
these variables include the imprecision of electromagnetic technology,
mine conditions, and machine relay activation time. Commenters stated
that MSHA should consider a performance-based approach. One commenter,
however, agreed that a proximity detection system should cause a
machine to stop no closer than 3 feet from a miner.
The National Institute for Occupational Safety and Health (NIOSH)
recommended that MSHA use a performance-based approach because the
requirement to stop the machine no closer than 3 feet from a miner
would limit future technological innovations that could improve miner
safety. NIOSH stated that future ``intelligent'' systems, those that
monitor workers' positions and disable only unsafe movement, may not
require the entire machine to stop; rather they could restrict certain
motions of the machine. NIOSH stated that there are several advantages
to restricting certain motions of the machine including decreased
nuisance shut-downs; flexibility in operator position when close
proximity to the machine is needed; flexibility in operator position to
avoid other hazards; and increased safety and productivity.
MSHA's experience with testing and observing proximity detection
systems indicates that causing a machine to stop before contacting a
miner provides the required performance and appropriate protection. A
performance-based approach allows mine operators and manufacturers to
address mine- and machine-specific conditions when determining the
appropriate settings for the proximity detection system. Specific
conditions include steep or slippery roadways, tramming speed of
machinery, location of the miner-wearable component, and the accuracy
of the proximity detection system. Mine operators are responsible for
programming a proximity detection system to initiate the stop movement
function at an appropriate distance from a miner to assure that the
machine stops before it can contact a miner.
The final rule requires that a proximity detection system cause a
continuous mining machine to stop before contacting a miner. Stopping a
continuous mining machine consists of stopping the tramming and
conveyor swing movements that could cause the machine to contact a
miner. The machine must remain stopped while any miner is within the
programmed stop zone.
Commenters stated that a proximity detection system should only
stop the tram and conveyor boom swing movements and not de-energize the
entire continuous mining machine.
Unexpected tramming and conveyer boom swing movements can be
hazardous. Many pinning, crushing, and striking accidents occur as a
result of continuous mining machine tram or conveyor boom swing
functions. MSHA has determined that it is unnecessary to shut down the
machine to stop all machine movement because miners are protected by
stopping the tramming and conveyor swing movements. Shutting down the
machine causes stress on machine components. The requirement to stop
tram and conveyor boom swing movements that could contact a miner does
not prohibit the use of proximity detection systems that can pinpoint a
miner's location and prevent machine movements accordingly.
Final Sec. 75.1732(b)(1) requires that the proximity detection
system cause a machine, which is tramming from place-to-place or
repositioning, to stop before contacting a miner except for a miner who
is in the on-board operator's compartment. The final rule, like
proposed Sec. 75.1732(b)(1)(i), allows machines equipped with a
proximity
[[Page 2193]]
detection system to move if the only miner in proximity occupies the
operator's compartment. MSHA did not receive comments on proposed Sec.
75.1732(b)(1)(i).
Final Sec. 75.1732(b)(1) does not include proposed Sec.
75.1732(b)(1)(ii), which would have provided an exception for a miner
who is remotely operating a continuous mining machine while cutting
coal or rock. The proposal would have required the machine to stop
before contacting the machine operator. Commenters stated that the
proposed requirement would force miners to stand in a location with a
significantly higher risk of being struck by a shuttle car while
cutting or loading or turning a crosscut. Other commenters stated that
the proximity detection system should allow a continuous mining machine
operator to be located behind the rear bumper and adjacent to the
conveyor boom when cutting or loading. One commenter has experience
deactivating the proximity detection system when cutting or loading.
Another commenter stated that there is no history of accidents during
cutting or loading. Another commenter stated that a zone must be
provided to prevent forcing the continuous mining machine operator out
of a safe area and into the hazardous area around another piece of
equipment particularly, shuttle cars, ram cars, loading machines, and
scoops.
NIOSH recommended eliminating Sec. 75.1732(b)(1)(ii) as proposed.
NIOSH and other commenters stated there is no means currently available
in the MSHA-approved proximity detection systems for determining
whether the continuous mining machine is cutting coal/rock or only
running the cutter drum. NIOSH and other commenters also stated that
other activities may require an operator or miner to be closer than 3
feet to the continuous mining machine, such as positioning the conveyor
boom over the shuttle car or activating certain machine functions
during maintenance.
MSHA reviewed an internal study conducted in 2002 in which MSHA
studied the location of the remote-controlled continuous mining machine
operator relative to the machine during production and while tramming.
This internal study was included in the record for public review and
comment. MSHA found that using a proximity detection system during
cutting would be impractical due to where the continuous mining machine
operator has to stand to safely operate the machine. The use of the
proximity detection system on the continuous mining machine during
cutting of coal may place the operator in the path of other equipment.
The study concluded that the proximity detection system should be
activated while tramming but not be activated while cutting.
MSHA agrees with commenters who identified situations during
cutting when the proposed requirement, in some circumstances, may cause
miners to stand in a location with a higher risk of being struck by a
coal hauling machine. The continuous mining machine was tramming from
place-to-place or repositioning in all 34 fatal accidents (those
occurring in 1984 through 2013) that could have been prevented by the
use of proximity detection systems. MSHA recognizes that there are
certain mining operations where continuous mining machine operators
must get close to the machine to properly perform the required tasks
(e.g., turning crosscuts).
Under the final rule, mine operators must use proximity detection
systems that will cause a continuous mining machine, which is tramming
from place-to-place or repositioning, to stop before contacting a miner
(except for a miner who is in an on-board operator's compartment).
Tramming from place-to-place includes moving the machine from one
working face to another (i.e., place-changing). Repositioning includes
moving from one side of a cut to the other (commonly called setting
over) and also includes cleaning up loose coal or rock when not
cutting.
The final rule does not require that a proximity detection system
provide a warning or stop the continuous mining machine when it is
cutting coal or rock. This includes when the cutter head is used to
clean up coal or rock, such as after a roof fall. MSHA intends that the
proximity detection system be operational and function properly at all
times when the continuous mining machine is in use. However, it is not
required to provide a warning or stop machine movement when the
continuous mining machine is cutting coal or rock.
In MSHA's experience, when a continuous mining machine is cutting
coal or rock, the machine moves slower, reducing the hazard. This
reduced hazard is reflected by the absence of fatal accidents when
continuous mining machines are cutting. MSHA recognizes that if the
continuous mining machine operator is forced away from the machine, the
operator may be exposed to other hazards. The final rule is changed
from the proposal to allow miners to work in close proximity to the
continuous mining machine when it is cutting coal or rock to avoid
hazards related to other mobile machines.
Based on NIOSH recommendations, comments received, and MSHA
experience, MSHA is requiring proximity detection systems to cause a
machine, when tramming from place-to-place or repositioning, to stop
before contacting a miner. An exception is provided when relocating a
continuous mining machine from an unsafe location for repair when a
machine-mounted component of a proximity detection system is not
functioning properly.
Final Sec. 75.1732(b)(2) is changed from the proposal and requires
that a proximity detection system provide an audible and a visual
warning signal on the miner-wearable component and a visual warning
signal on the machine that alert miners before the system causes a
machine to stop. These warning signals must be distinguishable from
other signals. The proposal would have required either an audible or
visual warning signal, distinguishable from other signals, when the
machine is 5 feet and closer to a miner.
One commenter stated that both an audible and visual warning is
necessary when the continuous mining machine is 5 feet and closer to
the miner.
After considering comments, MSHA determined that a proximity
detection system must provide both an audible and visual warning signal
to any miner who may be in proximity to the continuous mining machine.
This provides an added margin of safety because audible signals may not
always be heard and visual signals may not always be seen.
The audible and visual warnings provided by miner-wearable
components allow the miner wearing the component to move away from the
machine before the proximity detection system causes the machine to
stop. The visual warning provided on the machine alerts the machine
operator as well as all miners near the machine.
Several commenters recommended a performance-based warning signal
requirement. One commenter stated that warning signals are critical to
the implementation of a proximity detection system, but that a 5-foot
warning is not practical for all mining conditions. This commenter
stated that the existing proximity detection technology cannot
guarantee a set distance from a person where the proximity detection
system would provide a warning due to electromagnetic variability and
environmental conditions. Several commenters stated that a warning
signal is unnecessary and may be a nuisance.
MSHA agrees with commenters who stated that a warning signal
requirement should be performance-based rather than the 5-foot distance
in the proposal. A performance-based approach allows mine operators and
manufacturers to
[[Page 2194]]
address mine- and machine-specific conditions, tramming speed of
machinery, location of the miner-wearable component, and accuracy of
the proximity detection system when determining the appropriate
settings for triggering warnings. MSHA anticipates that mine operators
and manufacturers will program a proximity detection system to provide
warnings at a distance that will allow the miner to move away before
the proximity detection system causes the machine to stop.
Final Sec. 75.1732(b)(2) does not include proposed paragraphs (i),
the exception to provide a warning signal for a miner who is in an on-
board operator's compartment, and (ii), the exception to provide a
warning signal for a miner who is remotely operating a continuous
mining machine while cutting coal or rock. The proposed paragraphs are
not needed because final Sec. 75.1732(b)(1) requires a proximity
detection system to cause a machine, which is tramming from place-to-
place or repositioning, to stop before contacting a miner. For the
reasons noted above, this final rule does not require the proximity
detection system to cause a machine to stop before contacting a miner
when cutting coal or rock as proposed. The exceptions are not needed.
Final Sec. 75.1732(b)(2) is performance-based and requires audible and
visual warning signals before causing a machine to stop.
Final Sec. 75.1732(b)(3), like the proposal, requires that a
proximity detection system provide a visual signal on the machine that
indicates the machine-mounted components are functioning properly.
A commenter stated that this provision should be removed because
the signal could give miners a false sense of security. Another
commenter stated that a proximity detection system should include a
diagnostic function that provides a visual signal that the system is
working properly. This commenter stated that a visual signal will allow
miners to readily determine that the system is functioning properly and
recommended that the signal be located where a miner can observe it
from all work locations.
MSHA agrees that the required visual signal allows miners to
readily determine that the machine-mounted components of a proximity
detection system are functioning properly. A light-emitting diode (LED)
would be an acceptable visual signal. The signal indicates that the
machine-mounted components are working properly.
A commenter stated that MSHA should clarify the term functioning
properly. MSHA considers the proximity detection system to be
functioning properly when the system is working as designed and will:
Cause the machine to stop before contacting a miner; provide audible
and visual warning signals, distinguishable from other signals, that
alert miners before causing the machine to stop; provide the required
visual signals on the machine; and prevent movement of the machine if
any machine-mounted component is not working as intended. If a miner-
wearable component malfunctions during the shift, a replacement must be
provided for the miner.
Final Sec. 75.1732(b)(4), similar to the proposal, requires that a
proximity detection system prevent movement of the continuous mining
machine if any machine-mounted component of the system is not
functioning properly. However, a system with any machine-mounted
component that is not functioning properly may allow machine movement
if it provides an audible or visual warning signal, distinguishable
from other signals, during movement. Such movement is permitted only
for purposes of relocating the machine from an unsafe location for
repair.
A commenter stated that a distinct audible or visual alarm will
make miners aware that the proximity detection system is not operating
normally. Several commenters recommended allowing a machine with a
malfunctioning proximity detection system to operate until the next
maintenance shift or up to 24 hours using alternative protective
measures. One commenter recommended that the rule permit a machine with
a malfunctioning proximity detection system to operate until finishing
the cut that is in progress. This commenter stated that completing the
cut should be permitted since there is no history of accidents during
cutting or loading. Another commenter supported the proposal but stated
that a machine with a malfunctioning proximity detection system should
only be moved under the direction of a qualified mechanic or certified
electrician. A commenter stated that MSHA should allow the machine to
continue moving with an audible or visual warning signal only for the
time necessary to move the machine to a safe location for repair before
the end of the current production shift.
The final rule is changed from the proposal to clarify that a
proximity detection system must prevent movement of the continuous
mining machine if any machine-mounted component of the system is not
functioning properly. MSHA intends for the proximity detection system
to prevent all machine movement. This includes the tramming and
conveyor swing movements that could cause the machine to contact a
miner, as well as other machine movements associated with cutting coal
or rock. Cutting cannot continue because the tramming function, which
is needed to keep the cutter head in contact with coal or rock, would
be disabled when machine-mounted components malfunction. A continuous
mining machine equipped with a malfunctioning machine-mounted component
could expose miners to pinning, crushing, and striking hazards. When
any machine-mounted component of the system is not functioning
properly, preventing all machine movement helps to assure that miners
are protected.
Final Sec. 75.1732(b)(4) provides for an exception to allow a
machine to be moved for repair if the system is not functioning
properly; the machine is in an unsafe location; and the system provides
an audible or visual warning signal, distinguishable from other
signals, during movement. Overriding the proximity detection system
should only occur for the time necessary to move the machine to a safe
location--for example, the time needed to move a continuous mining
machine from under unsupported roof to an appropriate repair location.
MSHA intends that machine movement be restricted to tramming and the
hydraulic functions necessary to move the continuous mining machine to
a safe location. Under the final rule, this movement is allowed only to
relocate the machine so repairs can be made safely.
The final rule does not require a mechanic or qualified electrician
to direct the relocation of a machine with a malfunctioning proximity
detection system. Mine operators must train machine operators, under
existing new task training requirements, to relocate a machine to a
safe location for repair.
This provision is changed from the proposal to clarify that the
warning signal must be provided by the proximity detection system.
Either an audible or visual signal is sufficient warning when the
machine is moving while any machine-mounted component of the proximity
detection system is not functioning properly. In MSHA's experience,
both types of warning signals are not necessary because miners are
generally aware if the machine is not functioning properly and the
machine will only be moved a limited distance in a supervised
environment.
Final Sec. 75.1732(b)(5), changed from the proposal, requires that
proximity detection systems be installed to prevent interference that
adversely affects performance of any electrical
[[Page 2195]]
system. The proposed rule would have required mine operators to prevent
interference with or from other electrical systems. The final rule
clarifies that mine operators must prevent interference that adversely
affects performance of any electrical system.
A commenter stated that if there are interference issues with a
proximity detection system, the problems need to be identified,
resolved, and shared with the rest of the industry. Commenters stated
there are several electrical devices at risk for interference and this
interference may occur when kneeling in close proximity to loops of
cables, such as in low seam mines where experience with proximity
detection systems is limited. A commenter stated that a final rule
should require installation such that electrical interference from
other devices does not affect proper functioning.
Electrical systems used in the mine, including proximity detection
systems, can adversely affect the function of other electrical systems
through the generation of electromagnetic interference which includes
radio frequency interference. There have been instances of adverse
performance of a remote-controlled system, an atmospheric monitoring
system, and a machine-mounted methane monitoring system when a hand-
held radio was in use near the affected systems. Electromagnetic output
of approved proximity detection systems is substantially lower and uses
different frequencies than other mine electrical systems, such as
communication and atmospheric monitoring systems; therefore, the
likelihood of encountering interference issues is less, even in low
seam mines. Additionally, MSHA has not experienced issues with adverse
interference, with or from other electrical systems, associated with
the 425 systems in use on continuous mining machines in underground
coal mines.
The final rule requires the mine operator to evaluate the proximity
detection system and other electrical systems, including blasting
circuits, in the mine and take adequate steps to prevent adverse
interference. Steps could include design considerations, such as the
addition of filters or providing adequate separation between electrical
systems.
Final Sec. 75.1732(b)(6), changed from the proposal, requires that
a proximity detection system be installed and maintained in proper
operating condition by a person trained in the installation and
maintenance of the system.
One commenter stated that continuous mining machine operators,
mechanics, and electricians should receive training at the mine from
the manufacturer covering the operation, installation, and maintenance
of the system. Another commenter stated that MSHA should not mandate
training because either the persons can perform the work or they
cannot. Another commenter stated that all miners affected by a
proximity detection system should be trained as required by 30 CFR part
48 task training and, to prevent redundancy, there should not be
additional training requirements.
Based on MSHA's experience with testing of proximity detection
systems, the Agency has determined that proper functioning of a
proximity detection system is directly related to the quality of the
installation and maintenance of the systems. The training requirement
in the final rule for installing and maintaining a proximity detection
system is in addition to training required under existing part 48. The
new training requirement helps assure that the person performing the
installation and maintenance of a proximity detection system
understands the system and can perform the work necessary to assure
that the system operates properly. Appropriate training could include
adjusting detection zones, trouble-shooting electrical connections, and
replacing and adjusting machine-mounted and miner-wearable components.
MSHA anticipates that operators will assign miners to perform most
maintenance activities, but representatives of the manufacturer may
perform some maintenance. Based on Agency experience, operators will
generally arrange for proximity detection system manufacturers to
provide appropriate training to miners for installation and
maintenance. Miners receiving training from manufacturers'
representatives will, in most cases, provide training for other miners
who may undertake installation and maintenance duties at the mine. In
MSHA's experience, many mines use the train-the-trainer model for
installation and maintenance activities.
The final rule is changed from the proposal to clarify that the
proximity detection system must be installed and maintained in proper
operating condition. A system must operate properly to protect miners
near the machine. This includes the machine-mounted components and the
miner-wearable components. Mine operators will be expected to
demonstrate that a continuous mining machine equipped with a proximity
detection system in use at their mine is installed and maintained in
proper operating condition.
One method a mine operator could use to demonstrate that a
proximity detection system is operating properly to cause the machine
to stop before contacting a miner is to suspend a miner-wearable
component from the mine roof, move the machine towards the suspended
component, and after the proximity detection system causes the machine
to stop movement, determine whether the machine would have contacted a
miner. When making this determination, the position of the miner-
wearable component on the miner and the distance from the closest
surface of the continuous mining machine to the miner-wearable
component should be considered. Mine- and machine-specific conditions,
including steep or slippery roadways, tramming speed of machinery,
location of the miner-wearable component, and the accuracy of the
proximity detection system, should also be considered.
C. Sec. 75.1732(c) Proximity Detection System Checks
Final Sec. 75.1732(c), like the proposal, establishes requirements
for checking proximity detection systems.
Final Sec. 75.1732(c)(1) requires that operators designate a
person to perform a check of machine-mounted components of the
proximity detection system to verify that components are intact, that
the system is functioning properly, and take action to correct defects:
(i) At the beginning of each shift when the machine is to be used; or
(ii) immediately prior to the time the machine is to be operated if not
in use at the beginning of a shift; or (iii) within one hour of a shift
change if the shift change occurs without an interruption in
production. Final Sec. 75.1732(c)(1), unlike the proposal, does not
include the word ``visual'' because the check requires verification of
both the audible and visual warning signals under final Sec.
75.1732(b)(2).
A commenter stated that MSHA should require a mine operator to use
MSHA-approved written examination procedures for this check. This
commenter also recommended requiring a visual check by the machine
operator and a certified electrician or qualified mechanic. Another
commenter, however, stated that a requirement for a check was
unnecessary. A commenter also stated that MSHA should allow the
operator to determine how often and when the proximity detection system
is checked for proper operation. Other commenters stated that the
machine
[[Page 2196]]
hardware should be checked before each shift.
After reviewing the comments, MSHA determined that a check of the
machine-mounted components of a proximity detection system should be
performed before the continuous mining machine is operated each shift.
MSHA anticipates that the check will be performed at the same time as
the existing on-shift dust control parameter check. A check of machine-
mounted components of the proximity detection system is needed to
verify that components are intact and that the system is functioning
properly before the machine is operated. For example, some machine-
mounted components may be mounted on the outer surface of a continuous
mining machine and could be damaged when the machine contacts a rib or
heavy material falls against the machine. The person designated to
perform the check will walk around the machine to verify that machine-
mounted components are intact and the system is functioning properly.
The check will also include observation of appropriate audible and
visual warning signals. Operators can check that the system is
functioning properly by approaching the machine with a miner-wearable
component and observing changes in the system's warning signals as the
miner-wearable component enters the warning and stop zones.
MSHA believes that it is unnecessary to require written procedures
for the check because existing training regulations require that the
person designated to perform the check be trained to check the system.
The check supplements the design requirement in final Sec.
75.1732(b)(4) that prevents movement of the machine if any machine-
mounted component is not functioning properly. The system may not be
able to detect all types of damage, such as detached field generators,
which could affect proper function. The check helps assure that
machine-mounted components are positioned correctly and mounted
properly on the machine and the system will warn miners and stop
movement appropriately. Under existing Sec. 48.7, miners who perform
the required check must receive training in the safety and health
aspects and safe work procedures of the task.
In most cases, MSHA anticipates that the trained person designated
to make the on-shift dust control parameter check, required under
existing Sec. 75.362(a)(2), will also make the check of the proximity
detection system. MSHA also anticipates that both checks would be
performed at the same time. Unlike the examinations and tests required
under existing Sec. 75.512 for permissible equipment, it is not
essential to require a person qualified to perform electrical work to
conduct this check.
Final Sec. 75.1732(c)(2), like the proposal, requires that
operators check for proper operation of miner-wearable components at
the beginning of each shift that the components are to be used and
correct defects before the components are used.
Commenters recommended checking the miner-wearable component at the
beginning of each shift for damage. One commenter recommended checking
for sufficient power to work for the duration of the shift. A commenter
stated that defective miner-wearable components should be replaced
before that person goes underground. A commenter stated that it should
be up to the mine operator to determine how often and when the miner-
wearable component is checked for proper operation. Another commenter
stated that the final rule should allow an operator to designate a
person to check the miner-wearable component.
After considering comments, MSHA determined that the miner-wearable
components must be checked for proper operation at the beginning of
each shift that the component is to be used. This requirement helps
assure that the miner is protected before getting near a machine. MSHA
anticipates that each miner equipped with a miner-wearable component
will check the component to see that it is not damaged and has
sufficient power. The proximity detection systems that use these
components can only function properly if the miner-wearable components
have sufficient power.
MSHA intends that this check can be similar to the check that a
miner performs on a cap lamp prior to the beginning of a shift. A mine
operator, however, could also designate a person to check miner-
wearable components before they are used. Mine operators must provide
new task training, under 30 CFR part 48, for miners who will be
checking the miner-wearable components. If any defect is found, the
final rule requires that it be corrected before the component is used.
This helps assure that the miner-wearable component functions properly
and reduces the risk of injuries and fatalities from miners' exposure
to pinning, crushing, and striking hazards.
The final rule does not include proposed Sec. 75.1732(c)(3). This
proposed provision would have required the operator to designate a
person under MSHA's existing standard for qualified electricians to
examine proximity detection systems for conformance with the
performance requirements of this section at least every seven days and
that defects in the proximity detection system be corrected before the
machine is returned to service.
A commenter stated that a trained, qualified maintenance person
should examine the basic functions of proximity detection systems every
seven days by checking zone sizes, system communication, and warning
signals; examine at regular maintenance intervals and for each
modification to the machine or environment; and perform the examination
while the machine is not in service. This commenter stated that the
maintenance person should fully understand how the system works. Other
commenters stated that the electrical examination should take place on
a weekly basis at the same time as the other electrical examinations
required under Sec. 75.512. A commenter also stated that requiring an
examination each week is not needed.
After considering comments, MSHA concluded that the examinations of
proximity detection systems will take place with other electrical
examinations required under existing Sec. 75.512. MSHA determined that
the proposed requirement to designate a qualified person under existing
Sec. 75.153 to examine proximity detection systems at least every
seven days and correct defects is not necessary because the machine-
mounted components are electric equipment and must be examined, tested,
and properly maintained under existing Sec. 75.512. The miner-wearable
components are MSHA-approved intrinsically safe equipment and do not
need to be examined in accordance with existing Sec. 75.512.
Existing Sec. 75.512 requires electric equipment to be frequently
examined, tested, and properly maintained by a qualified person to
assure safe operating conditions. The examinations and tests required
under existing Sec. 75.512 must be made at least weekly under existing
Sec. 75.512-2, and the qualified person performing the examinations
and tests must meet the requirements to perform electrical work under
existing Sec. 75.153. Under existing Sec. 75.512, when a potentially
dangerous condition is found on electric equipment, such equipment must
be removed from service until such condition is corrected. The on-shift
check required in final Sec. 75.1732(c)(1) helps assure that proximity
detection systems function properly between the weekly examinations
required under existing Sec. 75.512.
[[Page 2197]]
D. Sec. 75.1732(d) Certifications and Records
Final Sec. 75.1732(d), like the proposal, establishes requirements
for certifications and records for proximity detection systems.
Final Sec. 75.1732(d)(1), like the proposal, requires that at the
completion of the check required under paragraph (c)(1) of this
section, a certified person under existing Sec. 75.100 certify by
initials, date, and time that the check was conducted. Defects found as
a result of the check under paragraph (c)(1) of this section, including
corrective actions and dates of corrective actions, must be recorded.
A commenter supported the proposed requirement that the mine
operator record any defect and corrective action. Another commenter
recommended that the record of any defect or corrective action be made
at the end of the shift and kept in a book on the surface. Another
commenter, however, supported the requirement to certify the check
required in paragraph (c)(1), but stated there was no safety benefit to
requiring a record of defects or corrective actions. Other commenters
indicated that there is no need to require records specifically for
proximity detection systems and that these records would be a burden.
The certification in final paragraph (d)(1) helps assure compliance
and provides miners on the section a means to confirm that the required
check was made. MSHA anticipates that, in most cases, the person making
the certification of the on-shift examination under existing Sec.
75.362(g)(2) will also make the certification of this check at the same
time.
The record of defects and corrective actions as a result of the
check required under final paragraph (c)(1) of this section must be
made by the completion of the shift, which is consistent with the
requirements for records of hazardous conditions in existing Sec.
75.363(b). If no defect is found, no record is needed. The requirement
in final paragraph (d)(1) of this section requires a record of defects
and corrective actions. This record can be used to show a history of
machine-mounted component defects that can alert miners,
representatives of miners, mine management, manufacturers, and MSHA of
recurring problems.
Final Sec. 75.1732(d)(2), like the proposal, requires the operator
to record defects found as a result of the check of miner-wearable
components under final paragraph (c)(2) of this section, including
corrective actions and dates of corrective actions.
A commenter supported the proposed requirement that the mine
operator record any defect and corrective action, but also stated that
the check of the miner-wearable component must be recorded. Another
commenter stated that the record of any defect or corrective action be
made at the end of the shift and kept in a book on the surface. A
commenter also stated there was no safety benefit to requiring a record
of defects or corrective actions. Other commenters indicated that there
is no need to require records specifically for proximity detection
systems and that these records would be a burden.
The requirement in final Sec. 75.1732(d)(2) provides for a record
of defects and corrective actions. This record can be used to show a
history of miner-wearable component defects that can alert miners,
representatives of miners, mine management, manufacturers, and MSHA of
recurring problems. For miner-wearable components, no record is needed
unless a defect is found. A certification of the check for proper
operation of miner-wearable components that is required under final
Sec. 75.1732(c)(2) is not necessary because miners can readily check
to confirm that the component is working.
The final rule does not include the provisions in proposed Sec.
75.1732(d)(3). The proposal would have required that: (1) The operator
make and retain records at the completion of the weekly examination
under proposed Sec. 75.1732(c)(3); (2) the qualified person conducting
the examination record and certify by signature and date that the
examination was conducted; and (3) defects, including corrective
actions and dates of corrective actions, be recorded.
A commenter supported the proposed requirement but also stated that
a maintenance supervisor should be required to countersign the record.
Another commenter indicated that the electrical examination of
proximity detection systems should be recorded consistent with the
recordkeeping requirement under existing Sec. 75.512 and that it would
be unnecessary and burdensome for this record to include a record of
defects found and corrective actions. Another commenter stated that
maintaining separate records for weekly inspections of proximity
detection systems is redundant to records already being maintained.
Another commenter stated this requirement would increase the paperwork
burden on a mine operator.
After considering the comments, MSHA determined that a separate
examination under proposed paragraph (c)(3) and existing requirements
under Sec. 75.512 are redundant. Accordingly, the corresponding record
requirement under proposed paragraph (d)(3) is not required by the
final rule. As required under existing Sec. 75.512, electric equipment
must be frequently examined, tested, and properly maintained by a
qualified person to assure safe operating conditions; and a record of
this examination must be kept and made available to an authorized
representative of the Secretary and to the miners. Consistent with MSHA
policy, if dangerous conditions and corrective actions are not
recorded, the records of weekly examinations of electric equipment are
incomplete.
Final Sec. 75.1732(d)(3), like proposed Sec. 75.1732(d)(4),
requires that the operator make and retain records of the persons
trained in the installation and maintenance of proximity detection
systems.
One commenter stated that a record is necessary to assure that the
person assigned to install and perform maintenance on proximity
detection systems has been trained. Other commenters stated that this
requirement would be redundant. One of these commenters stated that it
would be redundant with existing Sec. 75.159, which requires a list of
all qualified persons designated to perform duties under part 75. This
commenter stated that MSHA Form 5000-23 (Certificate of Training)
includes this information and that, due to this redundancy, the
requirement in proposed paragraph (d)(4) of this section should not be
included in the final rule. Other commenters indicated that this
requirement would be impractical when the installation or maintenance
is performed by a third party. Another commenter indicated this
requirement would increase the paperwork burden for a mine operator.
Final Sec. 75.1732(d)(3) requires the mine operator to make a
record of persons trained to install and perform maintenance on
proximity detection systems. MSHA anticipates that many mine operators
will train qualified persons, as defined by existing Sec. 75.153, to
install and perform maintenance on proximity detections systems; but,
the mine operator may train another miner who is not included on the
list required under existing Sec. 75.159. A mine operator may make the
record of the persons trained under final paragraph (d)(3) of this
section using existing MSHA Form 5000-23. Consistent with existing
practice, mine operators do not need to make and retain records of
training for proximity detection system manufacturers' employees who
install or perform maintenance on their systems.
[[Page 2198]]
Final Sec. 75.1732(d)(4), like proposed Sec. 75.1732(d)(5),
requires the operator to maintain records in a secure book or
electronically in a secure computer system not susceptible to
alteration.
One commenter supported the proposal. Another commenter stated that
this requirement should be removed because the underlying recordkeeping
requirements in proposed paragraph (d) of this section are redundant.
Another commenter stated that this requirement would create another
record book for mine operators to maintain and that this would increase
their paperwork burden.
The records required under final Sec. Sec. 75.1732(d)(1), (d)(2),
and (d)(3), if recorded in a book, must be in a book designed to
prevent the insertion of additional pages or the alteration of
previously entered information in the record. Based on MSHA's
experience with other safety and health records, the Agency believes
that records should be maintained so that they cannot be altered. In
addition, electronic storage of information and access through
computers is increasingly a common business practice in the mining
industry. This provision permits the use of electronically stored
records provided they are secure, not susceptible to alteration, and
able to capture the information and signatures required. Care must be
taken in the use of electronic records to assure that the secure
computer system will not allow information to be overwritten after
being entered. MSHA believes that electronic records meeting these
criteria are practical and as reliable as paper records. MSHA also
believes that once records are properly completed and reviewed, mine
management can use them to evaluate whether the same conditions or
problems, if any, are recurring, and whether corrective measures are
effective.
The final rule provides mine operators flexibility to maintain the
records in a secure book or electronically in a secure computer system
that they already use to satisfy existing recordkeeping requirements.
Final Sec. 75.1732(d)(5), like proposed Sec. 75.1732(d)(6),
requires that the operator retain records for at least one year and
make them available for inspection by authorized representatives of the
Secretary and representatives of miners.
A commenter supported the proposal but stated that hard copies of
this information must be made available if the lack of computer skills
would prohibit a miner from viewing this information. Another commenter
stated that this requirement should be removed because the underlying
recordkeeping requirements in paragraph (d) of this section are
redundant with existing requirements. This commenter stated that this
requirement would increase a mine operator's paperwork burden.
This provision applies to the records required under final
Sec. Sec. 75.1732(d)(1), (d)(2), and (d)(3). These records must be
made available for inspection to representatives of miners and MSHA.
The operator may provide access electronically or by providing paper
copies of records. MSHA believes that keeping records for one year
provides a history of the conditions at the mine to alert miners,
representatives of miners, mine management, manufacturers, and MSHA of
recurring problems.
E. New Technology
The final rule does not include proposed Sec. 75.1732(e) that
would have addressed technologically advanced proximity detection
systems because the final rule allows for flexibility in system design.
The final rule is performance-based and does not require specific
distances for stopping the machine or for warning miners. Proposed
Sec. 75.1732(e) would have provided that mine operators or
manufacturers could apply to MSHA for acceptance of a proximity
detection system that incorporates new technology.
A commenter stated that it was unclear whether proposed Sec.
75.1732(e) refers to approval of a petition for modification or a way
for MSHA's Approval and Certification Center (A&CC) to approve a
proximity detection system. A commenter was uncertain as to how this
provision would apply to manufacturers. Another commenter stated that
MSHA should clarify the scope of this provision and provide testing
requirements to assure proximity detection systems are safe and
effective for their intended use. Commenters stated that MSHA must
accept new technology if (1) it meets current permissibility
requirements, (2) performs the same function as already accepted
systems, or (3) is as safe as the proposed requirements.
Proposed Sec. 75.1732(e) would have addressed technologically
advanced proximity detection systems that did not meet the prescriptive
requirements for causing a machine to stop no closer than 3 feet from a
miner and for providing an audible or visual warning signal when the
machine is 5 feet and closer to a miner. Many comments to proposed
Sec. Sec. 75.1732(b)(1) and (b)(2) stated the Agency should change
requirements to a performance-based approach. The performance-based
requirements in this final rule allow for flexibility in system design,
eliminating the need for the proposed new technology provision.
III. Regulatory Economic Analysis
A. Executive Orders 12866 and 13563: Regulatory Planning and Review
Executive Orders 12866 and 13563 direct agencies to assess all
costs and benefits of available regulatory alternatives and, if
regulation is necessary, to select regulatory approaches that maximize
net benefits (including potential economic, environmental, public
health and safety effects, distributive impacts, and equity). Executive
Order 13563 emphasizes the importance of quantifying both costs and
benefits, of reducing costs, of harmonizing rules, and of promoting
flexibility. To comply with these Executive Orders, MSHA has prepared a
Regulatory Economic Analysis (REA) for the final rule. The REA contains
supporting data and explanation for the summary information presented
in this preamble, including the covered mining industry, costs and
benefits, feasibility, small business impacts, and Paperwork Reduction
Act requirements.
On April 23, 2014, the State of West Virginia issued a rule
governing proximity detection systems, effective July 1, 2014. The rule
requires, among other things, that proximity detection systems be
installed on place-change continuous mining machines in underground
sections of coal mines according to a 34-month phase-in schedule. The
regulatory economic analysis addresses cost and benefit changes to this
rule due to the West Virginia Rule in Chapter 5, Summary of Adjustments
for West Virginia Rule.
The Commonwealth of Virginia issued a memorandum to coal mine
operators (DM-14-03, August 18, 2014) stating that, effective October
1, 2014, all remote-control operated continuous mining machines be
equipped with proximity detection systems or use a designated spotter
during equipment moves.
MSHA anticipates that mine operators in the Commonwealth of
Virginia would opt to use a designated spotter instead of incurring the
expense of installing proximity detection systems on continuous mining
machines. The Agency estimates that the cost of diverting resources to
assure that there is a designated spotter for those continuous mining
machines during equipment moves would be de minimis. MSHA does not
address Virginia's memorandum in the regulatory
[[Page 2199]]
economic analysis (REA) because it does not affect the impact of the
final rule.
MSHA received comments on the preliminary regulatory economic
analysis and those comments are addressed in the REA. The REA can be
accessed electronically at http://www.msha.gov/REGSINF5.HTM or http://www.regulations.gov. A copy of the REA can be obtained from MSHA's
Office of Standards, Regulations and Variances at the address in the
Availability of Information section of this preamble.
Under E.O. 12866, a significant regulatory action meets at least
one of the following conditions: Having an annual effect on the economy
of $100 million or more, creating a serious inconsistency or
interfering with an action of another agency, materially altering the
budgetary impact of entitlements or the rights of entitlement
recipients, or raising novel legal or policy issues. The Office of
Management and Budget (OMB) has determined that this final rule would
be a significant regulatory action because it raises novel legal or
policy issues.
B. Population at Risk
The final rule applies to all underground coal mines in the United
States. In 2013, there were approximately 326 active underground coal
mines using continuous mining machines employing approximately 42,314
miners (excluding office workers).
C. Net Benefits
Under the Mine Act, MSHA is not required to use estimated net
benefits as the basis for its decision. At a 7 percent discount rate
over 10 years, the estimated annualized values for net benefits of this
rule after adjusting for West Virginia are $1.3 million; benefits are
$6.0 million and costs are $4.7 million. At a 3 percent discount rate
over 10 years, the estimated annualized values for net benefits of this
rule after adjusting for West Virginia are $1.8 million; benefits are
$6.5 million and annualized costs are $4.7 million.
MSHA anticipates several benefits from the final rule that were not
quantified due to a lack of definitive information. For example, MSHA
anticipates that the final rule will result in additional savings to
mine operators by avoiding the production delays typically associated
with mine accidents. Pinning, crushing, or striking accidents can
disrupt production at a mine during the time it takes to remove the
injured miner, investigate the cause of the accident, and clear the
accident site. Such delays can last for a shift or more. Factors such
as lost wages, delayed production, and other miscellaneous expenses,
could result in significant costs; however, MSHA has not quantified
these savings due to a lack of specific information. The monetized
benefits and costs are explained further in sections D and E.
D. Benefits
The final rule will significantly improve safety protections for
underground coal miners by reducing their risk of being crushed,
pinned, or struck by continuous mining machines.
MSHA reviewed the Agency's investigation reports for all continuous
mining machine accidents that occurred from 1984 through 2013 and
determined that the use of proximity detection systems could have
prevented 34 fatalities and 238 nonfatal injuries involving pinning,
crushing, or striking accidents with continuous mining machines. From
2010 through 2013, six underground coal miners working in close
proximity to continuous mining machines died from pinning, crushing, or
striking accidents. MSHA's review concluded that the latest 15 years of
data was the most appropriate data to project the number of incidents
over the next 10 years. Based on the data, MSHA projects that the rule
will prevent approximately 49 injuries and 9 deaths over the next 10
years.
To estimate the monetary values of the reductions in deaths and
nonfatal injuries, MSHA uses an analysis of the imputed values based on
a Willingness-to-Pay approach. This approach relies on the theory of
compensating wage differentials (i.e., the wage premiums paid to
workers to accept the risk associated with various jobs) in the labor
market. A number of studies have shown a correlation between higher job
risk and higher wages, suggesting that employees demand monetary
compensation in return for incurring greater risk. The benefit of
preventing a fatality is measured by what is conventionally called the
Value of a Statistical Life (VSL), defined as the additional cost that
individuals would be willing to bear for improvements in safety (that
is, reductions in risks) that, in the aggregate, reduce the expected
number of fatalities by one.
Under the proposed rule, the value of deaths and injuries prevented
were based on a 2003 meta-analysis by Viscusi & Aldy. Viscusi and Aldy
did an analysis of several studies that use a Willingness-to-Pay
methodology to estimate the imputed value of life-saving programs.
Updating the 2003 values for inflation yields an estimate in 2013
dollars of $8.7 million for each fatality prevented and $65,000 for
each nonfatal injury prevented for the lowest estimate.
For the final rule, MSHA revised the Agency's approach for
monetizing the value of fatalities prevented to provide a range of
VSLs. The regulatory economic analysis provides more detail; but, in
summary, MSHA estimated three alternatives for VSL.
Low Benefit Estimate: The low estimate of $8.7 million is from the
2003 Viscusi and Aldy estimate used in the proposed rule. However, this
estimate does not include adjustments for real income changes.
Primary Benefit Estimate: MSHA used a primary estimate of $9.2
million that is based on the new research and guidance by the
Department of Transportation (DOT). MSHA reviewed DOT's findings and
adjusted the VSL for real income growth. With the adjustment, the VSL
reaches approximately $10 million in the 10th year.
High Benefit Estimate: MSHA used a high estimate of $11.1 million
based on Viscusi's 2013 article that emphasizes, when possible, that
labor characteristics should be used to develop VSLs. The 2013 article
includes information that mining has one of the highest fatality rates
and that estimates should capture industry or occupation specific
information. As in the primary estimate, MSHA also applied the real
income growth each year to generate VSLs for the 10 years after the
final rule is effective. This provides a final value after 10 years of
approximately $12 million.
More detailed information about how MSHA estimated the primary
benefits and alternate benefits estimates are available in the REA
supporting this final rule.
E. Compliance Costs
MSHA estimated costs of the final rule based on the analysis of the
most likely actions that operators will need to take to comply with the
final rule. MSHA estimates that proximity detection systems purchases
and installations in underground coal mines will occur over 3 years
with 20 percent installed in the first year the rule is in effect, an
additional 40 percent installed in the second year, and the remaining
40 percent installed in the third year. MSHA estimates a useful life of
10 years for all machine-mounted components of proximity detection
systems and 5 years for miner-wearable components.
MSHA estimates that, after adjusting for the West Virginia Rule,
the total undiscounted cost of the final rule over a 10-year period is
$46.7 million, $41.3
[[Page 2200]]
million at a 3 percent rate, and $35.7 million at a 7 percent rate. The
corresponding values annualized over 10 years are $4.7 million
(undiscounted), $4.7 million (3 percent), and $4.7 million (7 percent).
IV. Feasibility
The requirements of the final rule are both technologically and
economically feasible.
A. Technological Feasibility
The final rule is technologically feasible. The final rule is not
technology-forcing and does not involve new scientific or engineering
knowledge. The technology necessary to meet the requirements of the
final rule already exists, is commercially available, and is in use in
underground coal mines. By allowing mine operators to phase in the
installation of proximity detection systems over a 36-month period, the
final rule provides coal mine operators sufficient time to obtain
necessary modification to the existing technology, obtain necessary
approvals, install proximity detection systems on continuous mining
machines, and train miners.
B. Economic Feasibility
MSHA has traditionally used a revenue screening test--whether the
estimated compliance costs of a standard are less than one percent of
revenues, or are negative (e.g., provide net cost savings) to establish
presumptively that compliance with the standard is economically
feasible for the mining industry. Based on this test, MSHA has
concluded that the requirements of the final rule are economically
feasible.
The estimated annualized compliance cost to underground coal mine
operators is $4.7 million. This represents less than one-tenth of one
percent of total annual revenue of $23.1 billion ($4.7 million costs/
$23.1 billion revenue) for all underground coal mines. Since the
estimated annualized compliance cost is below one percent of estimated
annual revenue, MSHA concludes that the final rule is economically
feasible for the underground coal industry.
V. Regulatory Flexibility Act and Small Business Regulatory Enforcement
Fairness Act
Under the Regulatory Flexibility Act (RFA) of 1980, as amended by
the Small Business Regulatory Enforcement Fairness Act (SBREFA), MSHA
has analyzed the compliance cost impact of the final rule on small
entities. Based on that analysis, MSHA certifies that the final rule
will not have a significant economic impact on a substantial number of
small entities. The factual basis for this certification is presented
in Chapter 7, Regulatory Flexibility Analysis, of the REA and is
summarized below.
A. Definition of a Small Mine
Under the RFA, in analyzing the impact of a rule on small entities,
MSHA must use the Small Business Administration's (SBA's) definition
for a small entity or, after consultation with the SBA Office of
Advocacy, establish an alternative definition for the mining industry
by publishing that definition in the Federal Register for notice and
comment. Because the Agency has not established an alternative
definition, MSHA is required to use SBA's definition. The SBA defines a
small entity in the mining industry as an establishment with 500 or
fewer employees.
MSHA has also examined the impact of the final rule on mines with
fewer than 20 employees, which MSHA and the mining community have
traditionally referred to as small mines. These small mines differ from
larger mines not only in the number of employees, but also in economies
of scale in material produced, in the type and amount of production
equipment, and in supply inventory. Therefore, their costs of complying
with MSHA's rules and the impact of the Agency's rules on them will
also tend to be different.
This analysis complies with the requirements of the RFA for an
analysis of the impact on ``small entities'' while continuing MSHA's
traditional definition of ``small mines.''
B. Factual Basis for Certification
MSHA's analysis of the economic impact on small entities begins
with a screening analysis. The screening compares the estimated yearly
costs of the final rule for small entities to their estimated annual
revenue. When estimated costs are less than one percent of estimated
revenues for small entities, MSHA believes it is generally appropriate
to conclude that the final rule will not have a significant economic
impact on a substantial number of small entities. If the estimated cost
is equal to or exceeds one percent of revenue, MSHA investigates
whether further analysis is required.
C. Derivation of Revenues and Costs for Mines
MSHA calculated the revenue for underground coal mines from data on
coal prices and production. The average open market U.S. sales price of
underground coal for 2013 was $67.56 per ton (estimated from Department
of Energy (DOE), Energy Information Administration (EIA), Annual Coal
Report 2012, December 2013, pg. 48, adjusted by the 2013 GDP deflator
from the Bureau of Economic Analysis (BEA)).
For mines excluding West Virginia, with 1-19 employees, 2013
underground coal revenue was $112 million (1.7 million tons x $67.56
per ton). For mines with 1-500 employees, 2013 underground coal revenue
was $12 billion (175.4 million tons x $67.56 per ton). Total 2013
underground coal revenue, excluding West Virginia, was $17.5 billion.
The 2013 total underground coal revenue including West Virginia was
$23.1 billion.
D. Screening Analysis for Underground Coal Mines
The estimated annualized cost of the final rule for underground
coal mines with 1-19 employees is approximately $0.5 million, which
represents approximately 0.5 percent of annual revenues.
When applying SBA's definition of a small mine, the estimated
annualized cost of the final rule for underground coal mines with 1-500
employees, excluding West Virginia, is approximately $4.1 million,
which represents less than one-tenth of one percent of annual revenue.
Table 1 shows MSHA's estimate of the annualized cost of the final
rule compared to mine revenue, by mine size. MSHA has provided, in the
REA accompanying this final rule, a complete analysis of the cost
impact.
[[Page 2201]]

1-500............................................................. 209 4.1 11,848 19,617 <0.1
All Mines......................................................... 220 4.7 17,518 21,364 <0.1
--------------------------------------------------------------------------------------------------------------------------------------------------------
Based on this analysis, MSHA has determined that the final rule
will not have a significant economic impact on a substantial number of
small underground coal mines.
VI. Paperwork Reduction Act of 1995
A. Summary
The Paperwork Reduction Act (PRA) provides for the Federal
government's collection, use, and dissemination of information. The
goals of the PRA include minimizing paperwork and reporting burdens and
ensuring the maximum possible utility from the information that is
collected (44 U.S.C. 3501). The information collections contained in
this final rule are submitted for review under the PRA to OMB, Control
Number 1219-0148. The final rule contains minor adjustments to burden
hours for an existing paperwork package with OMB Control Number 1219-
0066. MSHA does not include estimated burden hours and the cost of
revising training plans on an annual basis because this burden is
accounted for under the OMB Control Number 1219-0009. Underground coal
mine operators routinely revise their training plan at least yearly in
accordance with 30 CFR part 48.
MSHA estimates that in the first 3 years the final rule is in
effect, the mining community will incur 1,182 annual burden hours with
related annual burden hour costs of approximately $115,952 and other
annual costs related to the information collection of approximately
$22,359. A detailed explanation of the burden hours and related costs
are in the Paperwork Reduction Act section of the REA for this final
rule.
B. Procedural Details
The information collection package for this final rule was
submitted to OMB for review under 44 U.S.C. 3504, paragraph (h) of the
Paperwork Reduction Act of 1995, as amended. MSHA requested comment on
its estimates for information collection requirements in the proposal
and responded to these comments earlier in the preamble and in the REA.
The regulated community is not required to respond to any
collection of information unless it displays a current, valid, OMB
control number. (See 5 CFR 1320.5(a) and 1320.6.) MSHA displays the OMB
control numbers for the information collection requirements in its
regulations in 30 CFR part 3. The total information collection burden
is summarized as follows:
Title of Collection: Testing, Evaluation, and Approval of
Mining Products. OMB Control Number: 1219-0066.
Title of Collection: Training Plans and Records of
Training, for Underground Miners and Miners Working at Surface Mines
and Surface Areas of Underground Mines. OMB Control Number: 1219-0009.
Title of Collection: Proximity Detection Systems for
Continuous Mining Machines in Underground Coal Mines. OMB Control
Number: 1219-0148.

MSHA received comments on the information collection requirements
contained in the proposed rule. The comments are addressed in the
applicable sections of Section II, the Section-by-Section Analysis of
this preamble, and in the Supporting Statement for the information
collection requirements accompanying this final rule. The Information
Collection Supporting Statement is available at http://www.reginfo.gov/public/do/PRAMain, on MSHA's Web site at http://www.msha.gov/regspwork.htm, and at http://www.regulations.gov. A copy of the
Supporting Statement is also available from MSHA by request to Sheila
McConnell at [email protected], by phone request to 202-693-
9440, or by facsimile to 202-693-9441.
VII. Other Regulatory Considerations
A. The Unfunded Mandates Reform Act of 1995
MSHA has reviewed the final rule under the Unfunded Mandates Reform
Act of 1995 (2 U.S.C. 1501 et seq.). MSHA has determined that the final
[[Page 2202]]
rule does not include any federal mandate that may result in increased
expenditures by State, local, or tribal governments; nor does it
increase private sector expenditures by more than $100 million
(adjusted for inflation) in any one year or significantly or uniquely
affect small governments. Accordingly, the Unfunded Mandates Reform Act
of 1995 requires no further Agency action or analysis.
B. Executive Order 13132: Federalism
The final rule does not have ``federalism implications'' because it
does not ``have substantial direct effects on the States, on the
relationship between the national government and the States, or on the
distribution of power and responsibilities among the various levels of
government.'' Accordingly, under E.O. 13132, no further Agency action
or analysis is required.
C. The Treasury and General Government Appropriations Act of 1999:
Assessment of Federal Regulations and Policies on Families
Section 654 of the Treasury and General Government Appropriations
Act of 1999 (5 U.S.C. 601 note) requires agencies to assess the impact
of Agency action on family well-being. MSHA has determined that the
final rule has no effect on family stability or safety, marital
commitment, parental rights and authority, or income or poverty of
families and children. Accordingly, MSHA certifies that this final rule
does not impact family well-being.
D. Executive Order 12630: Government Actions and Interference With
Constitutionally Protected Property Rights
The final rule does not implement a policy with takings
implications. Accordingly, under E.O. 12630, no further Agency action
or analysis is required.
E. Executive Order 12988: Civil Justice Reform
The final rule is written to provide a clear legal standard for
affected conduct and was carefully reviewed to eliminate drafting
errors and ambiguities, so as to minimize litigation and undue burden
on the Federal court system. Accordingly, the final rule would meet the
applicable standards provided in section 3 of E.O. 12988, Civil Justice
Reform.
F. Executive Order 13045: Protection of Children From Environmental
Health Risks and Safety Risks
The final rule does not adversely impact children. Accordingly,
under E.O. 13045, no further Agency action or analysis is required.
G. Executive Order 13175: Consultation and Coordination With Indian
Tribal Governments
This final rule does not have ``tribal implications'' because it
does not ``have substantial direct effects on one or more Indian
tribes, on the relationship between the Federal government and Indian
tribes, or on the distribution of power and responsibilities between
the Federal government and Indian tribes.'' Accordingly, under E.O.
13175, no further Agency action or analysis is required.
H. Executive Order 13211: Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use
Executive Order 13211 requires agencies to publish a statement of
energy effects when a rule has a significant energy action that
adversely affects energy supply, distribution or use. MSHA has reviewed
this final rule for its energy effects because the final rule applies
to the underground coal mining sector. Because this final rule results
in annualized costs of approximately $4.7 million to the underground
coal mining industry, relative to annual revenues of $23.1 billion in
2013, MSHA has concluded that it would not be a significant energy
action because it is not likely to have a significant adverse effect on
the supply, distribution, or use of energy. Accordingly, under this
analysis, no further Agency action or analysis is required.
I. Executive Order 13272: Proper Consideration of Small Entities in
Agency Rulemaking
MSHA has reviewed the final rule to assess and take appropriate
account of its potential impact on small businesses, small governmental
jurisdictions, and small organizations. MSHA has determined and
certified that the final rule does not have a significant economic
impact on a substantial number of small entities.

2. Add Sec. 75.1732 to subpart R to read as follows:
Sec. 75.1732 Proximity detection systems.
Operators must install proximity detection systems on certain
mobile machines.
(a) Machines covered. Operators must equip continuous mining
machines, except full-face continuous mining machines, with proximity
detection systems by the following dates. For proximity detection
systems with miner-wearable components, the mine operator must provide
a miner-wearable component to be worn by each miner on the working
section by the following dates.
(1) Continuous mining machines manufactured after March 16, 2015
must meet the requirements in this section no later than November 16,
2015. These machines must meet the requirements in this section when
placed in service with a proximity detection system.
(2) Continuous mining machines manufactured and equipped with a
proximity detection system on or before March 16, 2015 must meet the
requirements in this section no later than September 16, 2016.
(3) Continuous mining machines manufactured and not equipped with a
proximity detection system on or before March 16, 2015 must meet the
requirements in this section no later than March 16, 2018. These
machines must meet the requirements in this section when placed in
service with a proximity detection system.
(b) Requirements for a proximity detection system. A proximity
detection system includes machine-mounted components and miner-wearable
components. The system must:
(1) Cause a machine, which is tramming from place-to-place or

correct defects--
(i) At the beginning of each shift when the machine is to be used;
or
(ii) Immediately prior to the time the machine is to be operated if
not in use at the beginning of a shift; or
(iii) Within 1 hour of a shift change if the shift change occurs
without an interruption in production.
(2) Check for proper operation of miner-wearable components at the
beginning of each shift that the components are to be used and correct
defects before the components are used.
(d) Certifications and records. The operator must make and retain
certifications and records as follows:
(1) At the completion of the check of machine-mounted components
required under paragraph (c)(1) of this section, a certified person
under Sec. 75.100 must certify by initials, date, and time that the
check was conducted. Defects found as a result of the check, including
corrective actions and dates of corrective actions, must be recorded
before the end of the shift;
(2) Make a record of the defects found as a result of the check of
miner-wearable components required under paragraph (c)(2) of this
section, including corrective actions and dates of corrective actions;
(3) Make a record of the persons trained in the installation and
maintenance of proximity detection systems required under paragraph
(b)(6) of this section;
(4) Maintain records in a secure book or electronically in a secure
computer system not susceptible to alteration; and
