the label. Wash water containing herbicide residues should be used only
on the site listed on the pesticide label.
Wash Water. Provide spill containment for indoor pesticide mixing
and storage facility only. Provide liquid spill collection system for outdoor
mixing facility (hardstand) connected to the industrial waste system only. Do
not connect drains from pesticide mixing areas, indoor or outdoor, to septic
systems, sanitary sewer, or storm water system.
Sanitary Sewer System and Drains. Consult local water quality
control regulations. Connect toilet, showers, and laundry plumbing fixtures
to a sanitary sewer system. Ensure that only rain or snow-melt water from the
roof is routed to storm drains. Pesticide wastes are generated routinely from
equipment washdown, laundry of work clothing, and personal decontamination.
Disposal of these wastes through the industrial waste system may be required
as determined by the installation. Other wastes may occur from actual
pesticide spills. Pesticide spills are addressed in para. 188.8.131.52, Spills and
Operational Note: Water resulting from washing the exterior of
dispersal equipment and vehicles may not be drained into the sanitary
sewer. Consult local water quality control regulations.
Sink. Provide a deep sink to fill and wash small equipment items
24 inches (610 mm) high and standard 5 gallon (19 L) cans. Install the hot
and cold water faucets so that an air gap of at least two diameters (minimum
of 2-inches (51 mm)) of discharge opening exists between the outlet of the
faucets and the top rim of the sink. The sink should be connected to the
industrial waste system. Swing-type spigots are recommended. Provide a
slotted hood or ventilator to each sink in the mixing area designed to enclose
the mixing operation as much as possible and to exhaust the vapors and dusts
away from personnel as illustrated in Facility Plate Sheet 10. Provide at
least 2 linear feet (610 mm) of counter top next to the sink (2 linear feet
(610 mm) of counter top on each side for double compartment sinks).
Operational Note: Where water quality regulations are especially
stringent and discharge to the sanitary or industrial waste system is
not an option, the sink should be drained to five gallon (19 L)
containers resting in a pit in the floor. In such a case, drainage from
the sink is severely limited and appropriate disposal procedures for the
container contents is required.
Provide a water heater if a source of hot water is
