Delineators will be used along the
perimeter of areas of the roadway where
no pipeline was laid and there was a
drop-off sufficient for equipment to
overturn. Delineators are installed along
the perimeter of the impoundment so
that, for both directions of travel, the
reflective surfaces of at least three
delineators along each elevation will
always be visible to the driver and
spaced at intervals sufficient to indicate
the edges and altitude of the roadway;
(6) access to the locked gate will be
limited to individuals who have
received and successfully completed
training consisting of applicable task
training, and a supervised tour of the
impoundment roadway. A training form
will be completed for each employee
that receives the training and will detail
the topics covered in the training.
Personnel deemed essential by the
petitioner to operate equipment in the
area who has not received the training
will be accompanied by a person who
has received the specified training.
Training will be valid for four years
from the date of completion; (7) records
of the training will be maintained for
four years and made available to MSHA
upon request; and (8) to enable U.S.
Silver to not berm the inside of the
impoundment roadway not only
prevents a diminution of safety for
miners, it provides an alternative
method of achieving the results of the
standard which at all times guarantees
no less than the same measure of
protection to all miners at the Galena
Mine afforded by the standard.

used to protect #2 AWG cables
exceeding 700 feet in length will have
instantaneous trip units calibrated to
trip at 800 AMPS. The trip settings of
these circuit breakers will be sealed and
will have permanent legible labels. The
label will identify the circuit breakers as
being suitable for protecting #2 AWG
cables; (6) replacement circuit breakers
and/or instantaneous trip units used to
protect #2 AWG trailing cables will be
calibrated to trip at 800 AMPS and this
setting will be sealed; (7) all circuit
breakers used to protect #2/0 AWG
trailing cables exceeding 850 feet in
length will have instantaneous trip units
calibrated to trip at 1500 AMPS. The
trip setting of these circuit breakers will
be sealed, or the maximum available
setting on the trip units will not be
greater than 1500 AMPS. These circuit
breakers will have permanent legible
labels. The label will identify the circuit
breaker as being suitable for protecting
#2/0 AWG cables; (8) replacement
breakers and/or instantaneous trip units
used to protect #2/0 AWG trailing cables
will be calibrated to trip at 1500 AMPS
and this setting will be sealed or
maximum size of the trip unit will be
1500 AMPS; (9) all components that
provide short circuit protection will
have a sufficient interruption rating in
accordance with maximum calculated
fault currents available; (10) during each
production day, persons designated by
the operator will visually examine the
trailing cables to ensure the cables are
in safe operating condition and that the
instantaneous settings of the specially
calibrated breakers do not have seals
removed or tampered with and they do
not exceed 500, 800 or 1500 AMPS
respectively; (11) any trailing cable that
is not in a safe operating condition will
be removed from service immediately
and repaired or replaced; (12) each
splice or repair in the trailing cables to
the Miner, Mobile Bridge Conveyor,
Roof Bolter or shuttle car will be made
in a workmanlike manner and in
accordance with the instructions of the
manufacturer of the splice or repair
materials. The splice or repair will
comply with 30 CFR 75.603 and 75.604
requirements; (13) permanent warning
labels will be installed and maintained

taken to ensure that haulage roads and
trailing cable storage areas are situated
to minimize contact of the trailing cable
with the Continuous Miner, Mobile
Bridge Conveyor, Shuttle Cars and Roof
Bolters. Trailing cables, anchors or cable
real equipment will be of permanent
type that minimizes the tensile forces on
the trailing cables; (15) where the
method of mining would require that
trailing cables cross roadways or
haulage ways, the cables will be
securely supported from the mine roof
or a substantial bridge for equipment to
pass over the cables will be provided
and used; (16) excess cable will be
stored behind the anchor or anchors on
equipment that uses cable reels to
prevent the cables from overheating;
(17) this change will not be
implemented until this petition for
modification is approved and all miners
who will be responsible for examining
the cables and associated electrical
components have been trained on the
contents and precautions included in
the petition; and (18) proposed revisions
for the approved Part 48 training plan
will be submitted to the District
Manager for the areas for which the
mines are located. The training will
include: (a) The hazards of setting the
short circuit interrupting device or
devices too high to adequately protect
the trailing cables; (b) how to verify that
the circuit interrupting devices
protecting the trailing cables are
properly set and maintained; (c) mining
methods and operating procedures that
will protect the trailing cables from
damage; (d) how to protect the trailing
cables against damage caused by
overheating cables due to excessive
cable stored on reels and adjusting
stored cable behind cable anchors as
tramming distances change; and (e)
proper procedures for examining the
trailing cable to ensure the cables are in
safe operating condition by a visual
inspection of the entire cable, observing
the insulation, the integrity of splices,
nicks and abrasions. The petitioner
further states that if regulations are
subsequently promulgated that
supersede the requirements of 30 CFR
75.503 (18.35(a)(5)(i), the standard,
unless it is determined by the Secretary
or his representative after opportunity
for input from the operator that the
alternative method contained in the
petition will at all times guarantee no
less than the same measure of protection
afforded the subsequent promulgated
standard. The petitioner asserts that the
proposed alternative method will
provide for a level of safety equal to or
greater than the statute in place.

The Department of Labor, as part of its
continuing effort to reduce paperwork
and respondent (i.e., employer) burden,
conducts a preclearance consultation
program to provide the public with an
opportunity to comment on proposed
and continuing information collection
requirements in accordance with the
Paperwork Reduction Act of 1995 (44
U.S.C. 3506(c)(2)(A)). This program
ensures that information is in the
desired format, reporting burden (time
and costs) is minimal, collection
instruments are clearly understood, and
OSHA’s estimate of the information
collection burden is accurate. The
Occupational Safety and Health Act of
1970 (the OSH Act) (29 U.S.C. 651 et
seq.) authorizes information collection
by employers as necessary or
appropriate for enforcement of the Act
or for developing information regarding
the causes and prevention of
occupational injuries, illnesses, and
accidents (29 U.S.C. 657). The OSH Act
also requires that OSHA obtain such
information with minimum burden
upon employers, especially those
operating small businesses, and to
reduce to the maximum extent feasible
unnecessary duplication of efforts in
obtaining information (29 U.S.C. 657).
Paragraph (a)(4) of the Standard
requires that employers obtain the

manufacturer’s written approval before
modifying a truck in a manner that
affects its capacity and safe operation; if
the manufacturer grants such approval,
the employer must revise capacity,
operation, and maintenance instruction
plates, tags, and decals accordingly. For
front-end attachments not installed by
the manufacturer, paragraph (a)(5)
mandates that employers provide a
marker on the trucks that identifies the
attachment, as well as the weight of
both the truck and the attachment when
the attachment is at maximum elevation
with a laterally centered load. Paragraph
(a)(6) specifies that employers must
ensure that the markers required by
paragraphs (a)(3) through (a)(5) remain
affixed to trucks and are legible.
Paragraphs (l)(1) through (l)(6) of the
Standard contain the paperwork
requirements necessary to certify the
training provided to powered industrial
truck operators. Accordingly, these
paragraphs specify the following
requirements for employers:
• Paragraph (l)(1)—Ensure that
trainees successfully complete the
training and evaluation requirements of
paragraph (l) prior to operating a truck
without direct supervision.
• Paragraph (l)(2)—Allow trainees to
operate a truck only under the direct
supervision of an individual with the
knowledge, training, and experience to
train operators and to evaluate their
performance, and under conditions that
do not endanger other employees. The
training program must consist of formal
instruction, practical training, and
evaluation of the trainee’s performance
in the workplace.
• Paragraph (l)(3)—Provide the
trainees with initial training on each of
22 specified topics, except on topics
that the employer demonstrates do not
apply to the safe operation of the
truck(s) in the employer’s workplace.
• Paragraphs (l)(4)(i) and (l)(4)(ii)—
Administer refresher training and
evaluation on relevant topics to
operators found by observation or
formal evaluation to have operated a
truck unsafely, been involved in an
accident or near-miss incident, or been
assigned to operate another type of
truck, or if the employer identifies a
workplace condition that could affect
safe truck operation.
• Paragraph (l)(4)(iii)—Evaluate each
operator’s performance at least once
every three years.
• Paragraph (l)(5)—Train rehires only
in specific topics that they performed
unsuccessfully during an evaluation and
that are appropriate to the employer’s
truck(s) and workplace conditions.
• Paragraph (l)(6)—Certify that each
operator meets the training and

as being suitable for protecting 2 AWG cables; (6) replacement
circuit breakers and/or instantaneous trip units used to protect
2 AWG trailing cables will be calibrated to trip at 800 AMPS
and this setting will be sealed; (7) all circuit breakers used to
protect 2/0 AWG trailing cables exceeding 850 feet in length
will have instantaneous trip units calibrated to trip at 1500 AMPS. The
trip setting of these circuit breakers will be sealed, or the maximum
available setting on the trip units will not be greater than 1500 AMPS.
These circuit breakers will have permanent legible labels. The label
will identify the circuit breaker as being suitable for protecting
2/0 AWG cables; (8) replacement breakers and/or instantaneous
trip units used to protect 2/0 AWG trailing cables will be
calibrated to trip at 1500 AMPS and this setting will be sealed or
maximum size of the trip unit will be 1500 AMPS; (9) all components
that provide short circuit protection will have a sufficient
interruption rating in accordance with maximum calculated fault
currents available; (10) during each production day, persons designated
by the operator will visually examine the trailing cables to ensure the
cables are in safe operating condition and that the instantaneous
settings of the specially calibrated breakers do not have seals removed
or tampered with and they do not exceed 500, 800 or 1500 AMPS
respectively; (11) any trailing cable that is not in a safe operating
condition will be removed from service immediately and repaired or
replaced; (12) each splice or repair in the trailing cables to the
Miner, Mobile Bridge Conveyor, Roof Bolter or shuttle car will be made
in a workmanlike manner and in accordance with the instructions of the
manufacturer of the splice or repair materials. The splice or repair
will comply with 30 CFR 75.603 and 75.604 requirements; (13) permanent
warning labels will be installed and maintained on the cover or covers
of the power center identifying the location of each sealed short
circuit protective drive. The labels will warn miners not to change or
alter these sealed short circuit settings; (14) in the event the mining
methods or operating procedures cause or contribute to the damage of
any trailing cable, the cable will be removed from service immediately
and repaired or replaced. Additional precautions will be taken to
ensure that haulage roads and trailing cable storage areas are situated
to minimize contact of the trailing cable with the Continuous Miner,
Mobile Bridge Conveyor, Shuttle Cars and Roof Bolters. Trailing cables,
anchors or cable real equipment will be of permanent type that
minimizes the tensile forces on the trailing cables; (15) where the
method of mining would require that trailing cables cross roadways or
haulage ways, the cables will be securely supported from the mine roof
or a substantial bridge for equipment to pass over the cables will be
provided and used; (16) excess cable will be stored behind the anchor
or anchors on equipment that uses cable reels to prevent the cables
from overheating; (17) this change will not be implemented until this
petition for modification is approved and all miners who will be
responsible for examining the cables and associated electrical
components have been trained on the contents and precautions included
in the petition; and (18) proposed revisions for the approved Part 48
training plan will be submitted to the District Manager for the areas
for which the mines are located. The training will include: (a) The
hazards of setting the short circuit interrupting device or devices too
high to adequately protect the trailing cables; (b) how to verify that
the circuit interrupting devices protecting the trailing cables are
properly set and maintained; (c) mining methods and operating
procedures that will protect the trailing cables from damage; (d) how
to protect the trailing cables against damage caused by overheating
cables due to excessive cable stored on reels and adjusting stored
cable behind cable anchors as tramming distances change; and (e) proper
procedures for examining the trailing cable to ensure the cables are in
safe operating condition by a visual inspection of the entire cable,
observing the insulation, the integrity of splices, nicks and
abrasions. The petitioner further states that if regulations are
subsequently promulgated that supersede the requirements of 30 CFR
75.503 (18.35(a)(5)(i), the standard, unless it is determined by the
Secretary or his representative after opportunity for input from the
operator that the alternative method contained in the petition will at
all times guarantee no less than the same measure of protection
afforded the subsequent promulgated standard. The petitioner asserts
that the proposed alternative method will provide for a level of safety
equal to or greater than the statute in place.
