Current through Register Vol. 48, No. 9, September 27, 2024
(a) Hazardous waste munitions and explosives
storage units must be designed and operated with containment systems, controls,
and monitoring, that:
(1) Minimize the
potential for detonation or other means of release of hazardous waste,
hazardous constituents, hazardous decomposition products, or contaminated
run-off, to the soil, ground water, surface water, and atmosphere;
(2) Provide a primary barrier, which may be a
container (including a shell) or tank, designed to contain the hazardous
waste;
(3) For wastes stored
outdoors, provide that the waste and containers will not be in standing
precipitation;
(4) For liquid
wastes, provide a secondary containment system that assures that any released
liquids are contained and promptly detected and removed from the waste area, or
vapor detection system that assures that any released liquids or vapors are
promptly detected and an appropriate response taken (e.g., additional
containment, such as overpacking, or removal from the waste area);
and
(5) Provide monitoring and
inspection procedures that assure the controls and containment systems are
working as designed and that releases that may adversely impact human health or
the environment are not escaping from the unit.
(b) Hazardous waste munitions and explosives
stored under this subpart may be stored in one of the following:
(1) Earth-covered magazines. Earth-covered
magazines must be:
(i) Constructed of
waterproofed, reinforced concrete or structural steel arches, with steel doors
that are kept closed when not being accessed;
(ii) Designed and constructed:
(A) To be of sufficient strength and
thickness to support the weight of any explosives or munitions stored and any
equipment used in the unit;
(B) To
provide working space for personnel and equipment in the unit; and
(C) To withstand movement activities that
occur in the unit; and
(iii) Located and designed, with walls and
earthen covers that direct an explosion in the unit in a safe direction, so as
to minimize the propagation of an explosion to adjacent units and to minimize
other effects of any explosion.
(2) Above-ground magazines. Above-ground
magazines must be located and designed so as to minimize the propagation of an
explosion to adjacent units and to minimize other effects of any
explosion.
(3) Outdoor or open
storage areas. Outdoor or open storage areas must be located and designed so as
to minimize the propagation of an explosion to adjacent units and to minimize
other effects of any explosion.
(c) Hazardous waste munitions and explosives
must be stored in accordance with a Standard Operating Procedure specifying
procedures to ensure safety, security, and environmental protection. If these
procedures serve the same purpose as the security and inspection requirements
of 264.14, the preparedness and prevention procedures of 264, subpart C, and
the contingency plan and emergency procedures requirements of 264, subpart D,
then these procedures will be used to fulfill those requirements.
(d) Hazardous waste munitions and explosives
must be packaged to ensure safety in handling and storage.
(e) Hazardous waste munitions and explosives
must be inventoried at least annually.
(f) Hazardous waste munitions and explosives
and their storage units must be inspected and monitored as necessary to ensure
explosives safety and to ensure that there is no migration of contaminants out
of the unit.
