under guidelines set forth in 40 CFR, Section 112.3(a), (b).
• Maintain adequate supplies of spill response equipment and materials in accessible locations near
areas where spills may be likely to occur.
Inspection and Training
■ Inspect waste containers frequently for leaks and proper closure seal.

Good Housekeeping(contd)
• Schedule waste pickup as frequently as necessary to keep storage of waste to a minimum and to
avoid overloaded/overfilled disposal containers.
■ Minimize spills and fugitive losses such as dust or mist from loading areas.
■ Maintain a minimal inventory of required chemicals to reduce the magnitude of potential spills and limit
waste generation.

- Evaluate the process generating the waste for pollution prevention opportunities.
- Maintain accurate information on waste streams using: manifests, bills of lading, biennial reports,
permits, environmental audits, SARA Title Ill reports, emission reports, Material Safety Data
Sheets (MSDS), NPDES discharge monitoring reports, inventory reports, data on chemical spills,
and emissions data.
■ Find substitutes for harmful chemicals.
■ Properly dispose of unusable chemical inventory.
Physical Site Usage

properly discharge to a permitted sanitary sewer connection, or recycle
the water.
• Conduct berm repair and patching.
• Inspect, clean, and maintain sumps and on-site treatment and
recycling units.
Contingency Response
■ Maintain adequate supplies of spill response equipment and materials
in accessible locations near area of activity.
Inspection and Training
• Provide the appropriate level of employee training in the following
areas: spill response and prevention, storm water pollution prevention
education (see SC-10 for storm water pollution educational
approaches), right-to-know awareness training, and hazardous
materials management.
■ Monitor flushing operations regularly to ensure that proper collection
and disposal of discharge is being performed.

BMP#14 POTABLE WATER SYSTEM FLUSHING
REQUIREMENTS:
■ Capital costs are low for implementation of collection system for aircraft potable water flushing.
• For new facility, capital costs vary depending on measures implemented.
- LOW COST: $500-$1,000 for berm construction.
- MEDIUM COST: $5,000-$20,000 for plumbing modifications (including re-routing discharge to
the sanitary sewer and installing a simple sump).
- HIGH COST: $30,000-$150,000 for on-site treatment and recycling.
LIMITATIONS:
• Some wastewater agencies may require pretreatment and monitoring of this type of discharge to
the sanitary sewer.

• Provide the appropriate level of employee training in the following
areas: spill response and prevention, storm water pollution prevention
education (see SC-10 for storm water pollution education approaches),
right-to-know awareness, and hazardous materials management.
• Inspect storm drain culverts or runway drainage areas after runway

■ Runway drainage patterns may not be suitable for the collection of
rubber particulates.

BMP#16 OIL/WATER SEPARATORS
PURPOSE: TARGETED ACTIVITIES
Oil/water separators are baffled chambers designed to remove petroleum < AircraftNehicle/
compounds and greases from storm water. Oil/water separators also remove Equipment Fueling
floatable debris and settled solids (sediment). < AircraftNehicle/
Equipment Washing
APPROACH TO FUTURE FACILITIES AND UPGRADES: < Fuel/Chemical Storage
Design of New Facilities and Existing Facility Upgrades: < Installing, Cleaning, and
OiVwater separators are typically used in areas where the concentrations of Maintaining Oil/Water
petroleum hydrocarbons,floatables, or sediment may be abnormally high and Separators
source control techniques are not very effective. There are two types of
oil/water separators: the American Petroleum Institute(API)separator and TARGETED POLLUTANTS
the coalescing plate separator(CPS). Design, sizing,and placement of
oil/water separators is dependent on several factors including: tributary area, < Oil and Grease
type of activity, pollutant type and concentration, and water temperature. < Fuel
General sizing guidelines for API separators include the following: < Floatables
< Sediment
■ Horizontal velocity: 3 feet per minute.
■ Depth of 3 to 8 feet. KEY APPROACHES
IN Depth-to-width ratio of 0.3 to 0.5.
IN Width of 6 to 16 feet. < Frequently inspect and
• Baffle height-to-depth ratios of 0.85 for top baffles and 0.15 for bottom clean separators
< Replace absorbent pads
baffles. as needed
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:
■ Separators must be inspected and cleaned frequently of accumulated oil,
grease, floating debris and sediments to be effective storm water quality
controls.
• Oil absorbent pads are to be replaced as needed but will always be
replaced prior to the wet season.
