2.1.6
Meteorological Information. The information provided for the design
of a facility incorporates meteorological data to establish structural and
mechanical criteria. Prevailing wind direction shall be used to site the
facility so that, in the event that toxic gases or smoke are released, the
effect on the populated or mission areas will be minimized.
2.1.7
Accessibility. The facility shall be located where there are access
roads of adequate load-bearing capacity and where routine through residential
areas will not be required.
2.2
General Requirements. Facilities be will designed to store
non-leaking containers labeled in accordance with Department of Transportation
(DOT)/Environmental Protection Agency (EPA) criteria. The use of direct
buried containers (i.e., tanks) will not be acceptable.
2.2.1
Enclosed or Open Facilities. General criteria for electrical
design, fire protections, ventilation, and materials of construction are
summarized in Table 1.
2.2.2
Safety.
2.2.2.1
Access and Exit. Access to and exit from the storage facility will
be restricted to periods when the facility is manned. During periods when the
facility is not manned, entrance shall be completely restricted either through
locked gates, door, or both. In accordance with 40 CFR 264.14 (c), a sign
visible from 8 meters (25 feet) shall be placed on all access roads and
entrances to the storage facility. The sign shall have the legend: "Danger -
Unauthorized Personnel Keep Out,"
2.2.2.2
Showers and Eyewash Station. Eyewash/deluge showers will be
provided within 10 seconds and within 100 feet of travel distance for both
long- and short-term storage facilities (in conformance with Emergency Eyewash
and Shower Equipment, ANSI Standard Z 358.1-1981).
2.2.2.3
Ventilation. All generally occupied areas (administrative,
latrines, etc.) shall follow the recommendations of the American Conference of
Government Industrial Hygienists (ACGIH), Industrial Ventilation, A Manual of
Recommended Practices, and shall have positive-pressure ventilation in
enclosed spaces, as shown in Table 1. Negative pressure shall be maintained
in all enclosed waste storage areas. Ventilation shall conform to OSHA
Standard 1910.106 for flammable liquid vapors. Dehumidification of the air
and exhausting the air to outside are recommended for storage areas containing
materials that react with water or that have corrosive vapors, specifically
the acid waste, and reactive waste storage areas. Storage and/or transfer
areas containing materials hazardous to health shall be ventilated.
2.2.2.4
Fire Protection. Fire protection shall be provided as required by
Construction Criteria Manual, DOD MIL-HDBK-1190. Since reactive wastes may
react violently with water, the storage area for these wastes shall be
protected by a gaseous-type system (i.e., CO2 or Halon 1301).
