Current through Register Vol. 51, page 43, September 23, 2024
After February 1, 1995, the following requirements for containment
apply to those operational areas where operational area containment is required
pursuant to §
12:56:17:01:
(1) Operational area activities must be
carried out in a manner that prevents escape of discharges that may result in
unreasonable adverse effects on the environment;
(2) Operational area activities must be
carried out on an impervious surface that is designed to catch and contain any
discharges in the operational area;
(3) The operational area containment must be
constructed in accordance with professional engineering practices which include
the following:
(a) The material used must be
of sufficient thickness and strength to withstand the weight and movement of
any equipment that may be placed or parked within the operational area
containment;
(b) All seams and
cracks must be sealed;
(c) The
operational area containment must be constructed of concrete or other materials
approved by the secretary prior to construction or installation. If materials
other than concrete are used, information must be provided by the applicant to
the secretary which includes chemical compatibility, permeability, and physical
characteristics of materials proposed to assure operational area containment
integrity under conditions of proposed use. A written confirmation of
compatibility of synthetic materials must be kept at the operational area or at
the nearest local office of the operator;
(d) For liquid pesticides, including
container and equipment rinsates, the operational area containment must be
curbed or sloped to contain discharges so as to facilitate recovery of
discharged materials and to prevent liquids from adjacent surfaces from flowing
onto the operational area containment. To prevent unreasonable adverse effects
on the environment as defined in SDCL chapter 38-21, the operational area
containment must be of sufficient capacity and surface area to contain
discharges from the single largest container or application system operated or
cleaned within the operational area and to prevent spillage onto unprotected
areas;
(e) For nonliquid
pesticides, the operational area containment must extend beneath any conveyors
or augers used in operational area activities unless the conveyors or augers
are fully enclosed and constructed to prevent discharge. To prevent
unreasonable adverse effects on the environment as defined in SDCL chapter
38-21, the operational area containment must be of adequate surface area to
contain discharges from the largest container or equipment operated within the
operational area containment. The operational area containment must be
constructed to prevent liquids from adjacent surfaces from flowing onto the
operational area containment;
(4) Discharges and other accumulated
materials must be promptly recovered from the operational area containment.
Accumulated liquids or materials containing pesticides must be disposed of in
accordance with chapter 12:56:02. Accumulations of precipitation may be
discharged from the operational area containment as surface runoff if the
operational area containment was cleaned after the last use.
