valves, and equipment when transporting waste to eliminate leakage
and spills.
v Use only surfactants and disinfectants approved for discharge to the
sanitary sewer system. Do not discharge or rinse other unapproved
chemicals or materials into the triturator facility. Any change in the
chemicals used in aircraft lavatory service operations must be
approved by the COP Aviation Department.
BMP#11-1

CHARLOTTE/DOUGLAS INTERNATIONAL AIRPORT
BMP#11 1 LAVATORY SERVICE OPERATIONS
Operational Considerations (contd)
v Perform surfactant/disinfectant mixing and transfers in the triturator area or under cover. This will
allow the rinsing of minor spills and splashes to enter the sanitary sewer system.
v Do not perform lavatory truck cleanout/backflushing at any location other than triturator facilities.
v Utilize buckets or pans to capture drippage from aircraft lavatory access fittings. Immediately dump
the drippage into the bulk storage tank on the service cart or truck.
v Carefully handle chemicals and chemical concentrates. Immediately collect dry chemicals or
absorb liquid chemicals for proper disposal. Do not hose down spills unless the discharge enters
the sanitary sewer system through a permitted connection (triturator facility).
v Practice good housekeeping techniques at the triturator facility. Immediately clean spills of wastes
and chemicals.
Contingency Response
v Maintain adequate supplies of spill response equipment and materials in accessible locations near
areas where spills may be likely to occur.
v Report any equipment malfunctions to Airport Operations.
Inspection and Training
v Perform regular inspections of the hose and fittings used for transferring lavatory waste. Keep the
equipment in good working order. Replace worn equipment before leaks develop. Notify
appropriate ground service personnel if it is noticed that the aircraft lavatory fittings require
maintenance.
v Provide the appropriate level of employee training in the following areas: spill response and
prevention, and stormwater pollution prevention education (see BMP#10 for stormwater pollution
education approaches).
REQUIREMENTS:
v Management practices are based on careful material handling, good housekeeping, and
awareness of maintenance requirements.
LIMITATIONS:
v Facilities may have a limited number of permitted sanitary sewer access points (triturator facilities)
for a large quantity of lavatory service equipment.

CPS separator sizing is more complex. Sizing calculations require the
inclusion of information such as packing plate surface areas and plate
angles. CPS separators can, due to their packed plate design, remove the
same quantities of oils and greases while occupying less space than API
separators.
APPROACH TO EXISTING FACILITY ACTIVITIES:
Operational Considerations:
v Separators must be inspected and maintained frequently of accumulated
oil, grease, floating debris, and sediments to be effective stormwater
quality controls.
