(a) A wastewater treatment facility must be completely
enclosed by an intruder-resistant fence.
(1) The intruder resistant fence must have a locked
gate at each access point.
(2) The intruder-resistant fence must be at least
6.0 feet tall, and the bottom of the fence must be close enough to
surface grade to prevent human access.
(3) The intruder-resistant fence must be constructed
of wood, concrete, masonry, or metal. Other materials may be used,
but only if approved in writing by the executive director.
(4) The top of the intruder-resistant fence must have
at least three strands of barbed wire. A fence that is at least 8.0
feet tall does not require barbed wire. The top of an intruder-resistant
fence may have outwardly-directed iron bars spaced on four-inch centers
instead of barbed wire.
(5) A five-strand barbed wire fence may be used in
a rural area for fencing lagoons or overland-flow plots, but only
if approved in writing by the executive director.
(b) A wastewater treatment facility must have hazard
signs on the outward facing side of the fence, stating "DANGER - NO
TRESPASSING" in English and Spanish. At least one clearly visible
and legible hazard sign must be placed on each gate and each side
fence.
(c) A wastewater treatment facility must be accessible
by truck during all weather conditions, including a 25-year, 24-hour
rainfall event, and must have at least one all-weather access road
with the driving surface situated above the 100-year flood plain.
