Current through Register Vol. 48, No. 38, September 20, 2024
a)
An owner or operator of a hazardous waste munitions and explosives storage unit
must design and operate the unit with containment systems, controls, and
monitoring that fulfill each of the following requirements:
1) The owner or operator minimizes the
potential for detonation or other means of release of hazardous waste,
hazardous constituents, hazardous decomposition products, or contaminated
run-off to the soil, groundwater, surface water, and atmosphere;
2) The owner or operator provides a primary
barrier, which may be a container (including a shell) or tank, designed to
contain the hazardous waste;
3) For
wastes stored outdoors, the owner or operator provides that the waste and
containers will not be in standing precipitation;
4) For liquid wastes, the owner or operator
provides a secondary containment system that assures that any released liquids
are contained and promptly detected and removed from the waste area or a 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) The owner or operator provides 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 EE may be stored in one of the following:
1) Earth-Covered Magazines. The owner or
operator of an earth-covered magazine must fulfill each of the following
requirements:
A) The magazine is constructed
of waterproofed, reinforced concrete or structural steel arches, with steel
doors that are kept closed when not being accessed;
B) The magazine is so designed and
constructed that it fulfills each of the following requirements:
i) The magazine is of sufficient strength and
thickness to support the weight of any explosives or munitions stored and any
equipment used in the unit;
ii) The
magazine provides working space for personnel and equipment in the unit;
and
iii) The magazine can withstand
movement activities that occur in the unit; and
C) The magazine is 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) An owner or operator must store hazardous
waste munitions and explosives in accordance with a Standard Operating
Procedure that specifies procedures which ensure safety, security, and
environmental protection. If these procedures serve the same purpose as the
security and inspection requirements of Section
725.114, the
preparedness and prevention procedures of Subpart C, and the contingency plan
and emergency procedures requirements of Subpart D, then the Standard Operating
Procedure may be used to fulfill those requirements.
d) An owner or operator must package
hazardous waste munitions and explosives to ensure safety in handling and
storage.
e) An owner or operator
must inventory hazardous waste munitions and explosives at least
annually.
f) An owner or operator
must inspect and monitor hazardous waste munitions and explosives and their
storage units as necessary to ensure explosives safety and to ensure that there
is no migration of contaminants out of the unit.
