A. ATRS
				systems and all other methods of temporarily supporting the roof shall be
				approved on an individual mine basis by the Chief or his authorized
				representative and shall become part of the approved roof control plan. Such
				approval of the ATRS system is not necessary if it has already been approved
				for the machine for which it was designed and meets the requirements in
				4VAC25-60-70.
B. Before an ATRS system is used underground,
				the operator shall obtain approval from the Chief or his authorized
				representative. Approval shall be in a form prescribed by the Chief and where
				conditions warrant shall address the need for and availability of ATRS mounted
				deflector pads or equivalent protective devices which promote safety for drill
				operators by reducing exposure to rock falling inby and deflecting back under
				the installed ATRS. Any ATRS system that has been approved prior to the
				effective date of this chapter shall also be deemed approved by the Chief or
				his authorized representative, provided such an ATRS system meets the minimum
				requirements set forth in this chapter.
C. The Chief may grant a waiver for an ATRS
				system where it has been proposed and proven effective by the operator and the
				Chief has determined that:
1. The use of an
				ATRS system would create a condition which will cause a greater hazard than the
				method presently being employed or proposed by the operator for temporarily
				supporting the roof; or
2. Where
				the technology of an ATRS system does not exist to allow compliance with the
				requirements set forth in this chapter.
In granting a waiver the Chief may approve the use of
				  alternative methods of temporary roof support.

				requirements unless a waiver has been granted by the Chief.
B. The controls to position the machine and
				place the ATRS system against the roof shall be operated from under permanently
				supported roof, or the controls may be located in a compartment which includes
				a deck that provides the equipment operator with overhead and lateral
				protection, and has the structural capacity to elastically support a dead
				weight load of at least 18,000 pounds.
C. The ATRS system shall be placed firmly
				against the roof before any work is performed inby permanent roof supports and
				shall remain against the roof while work is being done.
D. All hydraulic jacks affecting the support
				capacity of an ATRS system shall have check valves or equivalent protection to
				prevent support failure in the event of a sudden loss of hydraulic
				pressure.
E. ATRS systems used in
				conjunction with single bolt installation are required to elastically support,
				at a minimum, a deadweight load measured in pounds of at least 450 times each
				square foot of roof intended to be supported, but in no case less than 11,250
				pounds.
F. The actual capacity to
				elastically support a deadweight load shall be certified by a registered
				engineer. Documentation of the certification of the ATRS system shall be made
				available to the Chief or his authorized representative.
G. The distance that the ATRS system may be
				set inby the last row of permanent supports shall be dependent on the spacing
				requirements of the permanent roof supports and must be approved by the Chief
				or his authorized representative in the approved roof control plan.
H. No person shall work or travel beyond the
				ATRS system unless the distance between the coal face and the ATRS system is
				five feet or less. In addition, no person shall work or travel left or right of
				the ATRS unless a coal rib, a permanent support, or a temporary support is
				within five feet of the ATRS system. The only exception is that when a five
				foot limit is being measured from an ATRS system consisting of a ring, then the
				five foot limit shall be determined from the outside of the ring.
I. In no case shall the inch tram control
				speed exceed 80 feet per minute when the roof bolting machine is being used to
				establish the ATRS system.

C. Any disruption in
				communication which is not restored within one hour shall be recorded by the
				mine foreman in the on-shift report. The record shall reflect the corrective

D. Whenever a representative of the miners,
				or a miner where there is no such representative, has reason to believe that
				conditions are such that continuing to work on a section without communication
				would constitute an imminent danger to safety or health, such miner or
				representative shall notify the Chief of the Division of Mines or mine
