Energy conservation should be a major consideration in the design of building envelopes,
mechanical systems, and electrical systems for aircraft maintenance facilities. Refer to MIL-
HDBK1003/3, Heating, Ventilating, Air Conditioning, and Dehumidifying Systems. Each
building envelope should be insulated to provide the minimum heat transmission ("U") factors
practical to meet energy budgets.
The maintenance facilities should meet applicable pollution abatement criteria. For applicable
discharge criteria, NAVFACENGCOM Criteria Office and the cognizant EFD or EFA should be
consulted. Refer to MIL-HDBK-1005/8, Domestic Wastewater Control, MIL-HDBK-1005/9,
Industrial and Oily Wastewater Control
It is essential that, as part of the preliminary studies, consideration be given to water
conservation and source control, including the possibility of substantial alteration of the process
or plant operation to reduce pollutant loading. The greater the volume of wastewater to be
treated and the greater the amount of contaminant to be removed or destroyed, the higher are the
capital, labor, and material costs required. As a result, it is often economical to eliminate or
reduce the quantity of waste at its source prior to treatment or in place of treatment. Several
possible techniques exist including process change, material recovery, segregation, and water
reuse. Sometimes, with only partial purification, spent water can be reused, once or several
times, in the industrial process. Water unsuitable for direct reuse may be serviceable for a
different purpose, in which quality requirements are less restrictive.
Often, there are a number of alternatives that can achieve the desired result. Therefore, a major
objective of the preliminary studies should be to determine what combinations of actions will be
the most cost effective and technically and operationally feasible.
AFFF Disposal. The disposal of spent AFFF is dependent upon the water treatment facilities
which would treat the effluent from the discharge site. Depending upon the facility's location,
AFFF may require onsite containment.
Fire protection for aircraft maintenance facilities should be provided in accordance with UFC-3-
600-01; National Fire Protection Association (NFPA) 409, Aircraft Hangars; and Air Force
Regulation (AFR)-88-15, Criteria and Standards for Air Force Construction, as applicable to the
Anti-Terrorism / Force Protection (ATFP)
