Know the location of all separators and the point
of discharge (such as to storm sewers, sanitary sewers, septic
tanks, or discharge to surface waters).
Understand where the monitoring points are and
what the discharge limits are for separators.
i)Assist in eliminating unpermitted pollutants. Help
implement source control plans and identify problem areas where
industrial discharges that may contain hazardous wastes, heavy
metals, or emulsified oils are being discharged to an oil/water
separator system not designed to treat such wastes.
Identify to unit/activity personnel and the
environmental staff those oil/water separators that contain
excessive amounts of soilds. This characteristic may indicate
that exterior vehicle or equipment washing (which is usually not
allowed in maintenance areas) is being performed at maintenance
Educate installation staff to encourage use of dry
cleanup procedures. For example, floor drains from maintenance
areas to oil/water separators should be used only for final
rinsing of the floor after any oils or other spill materials are
cleaned up with dry materials.
Remove and test oil/water separator sludge prior
to disposal to ensure compliance with the sludge disposal
requirements. Normally the sludge is tested once, shortly after
the separator is placed in service, to characterize the settled
sludge. If the sludge is hazardous, the source of the hazardous
pollutants should be immediately identified and eliminated. The
sludge must be retested each time a significant change occurs in
the influent to the separator. Testing and appropriate sludge
disposal should be coordinated through your environmental office.
O&M of Oil/Water Separators. The ability of
oil/water separators to function properly depends on the
application of required routine service and maintenance.
Mechanical equipment associated with separators should be
maintained according to manufacturers' recommendations.
Personnel using and maintaining the system are expected
to understand the separation process and the components of the
specific oil/water separator. Maintenance personnel are expected
to be familiar with the piping and configuration of each
separator for which they are responsible. They should
periodically inspect all parts of the separator and its draining
system to prevent failures caused by operations, breaks, and
