Spills and Contaminated Water. Design storage and mixing areas
only with no drains to contain spills and water. See paragraph 126.96.36.199.
Pesticide spills and cleanup procedures are addressed in AFPMB Technical
Information Manual #15.
Operational Note. A spill kit, equal to that described in AFPMB TIM
#15, shall be available to use for pesticide spills. Spill kits shall
be available in the pest management facility and on each service
Holding Tanks. Do not design drainage to a holding tank.
tanks are prohibited in new construction.
Operational Note: Use of a holding tank for storage of any pesticide
could bring the installation under additional regulation and could
result in considerable unnecessary expense. Procedures are available
that preclude the need for holding tanks. These include but are not
limited to: (1) the practice of washing outdoor dispersal equipment at
the application site and applying the wash water to the area treated,
(2) using water from rinsing concentrate containers to make up finish
sprays, (3) saving wash water throughout the work day to be used in the
next days' operations, and (4) substituting the more hazardous or toxic
pesticides with safer, less persistent, biodegradable materials.
Prudent use of pesticides can materially reduce disposal requirements.
Never pour rinse liquids contaminated with pesticides on the ground or
into a sink or drain leading to a storm sewer system. Local water
quality regulations must be observed.
Hardstand Sump Drain. Provide a 3-inch (76-mm) 1/4 turn ball valve
fitted with a waterproof spring close/fail close (deadman) mechanism so that
the valve is closed to flow unless manually held open allowing drainage to the
industrial waste system to remove accumulated water. The valve shall be
protected with a steel grating with an opening to accommodate a removable
extension handle. The spring close mechanism shall be operated with a handle
that extends 30 inches (762 mm) above the grate. Facility Plate Sheet 11
illustrates a hardstand with sump, drain, and valve. A sign shall be provided
near the sump drain valve stating "RECOVER PESTICIDE SPILLS. USE VALVE TO
DRAIN WASH WATER AND RAIN."
Operational Note: Drains are maintained in a closed position and opened
only to drain off accumulated precipitation to prevent accidental
environmental contamination by spilled pesticides. Conduct maintenance
inspection of drain system monthly. Ground water contamination and
other adverse environmental effects can be avoided by using wash water
as the diluent for soil treatment for subterranean termites (if
permitted by the pesticide label) or dispersing the wash water over the
same outdoor area where the initial pesticide was applied according to
