Mich. Admin. Code R. 285.637.6 - Mixing and loading facilities
Rule 6.
(1)
Pesticide mixing or loading shall not occur at a mixing and loading facility
unless the mixing or loading is in compliance with the provisions of this
subrule. Mixing and loading shall only occur on a pad that is in compliance
with all of the following requirements:
(a)
The pad shall be constructed with impervious materials, such as sealed
concrete, plastic, stainless steel, fiberglass or other approved
materials.
(b) The pad shall be
bermed, curbed, sloped, or otherwise designed to contain spills, leaks,
releases, or other discharges that are generated during the mixing and loading
of pesticides or pesticide-containing materials.
(c) Pesticides or pesticide-containing
materials that are collected by the pad shall be contained either by the pad
itself or drained, pumped, or transferred to an additional impermeable,
aboveground holding tank or reservoir until utilized or disposed of in
compliance with applicable local, state, and federal laws. The holding tank or
reservoir shall be suitably constructed to prevent the release of pesticides or
pesticide-containing materials to the environment.
(d) The pad or holding tank or reservoir
shall be able to contain the amount of pesticide that could be discharged
during 1 minute of mixing or loading.
(e) Mixing or loading pads which are located
outdoors and which are not covered shall also meet either of the following
criteria:
(i) Have the capacity to contain a
6-inch rainfall.
(ii) Be cleaned of
all pesticide residues immediately after spills to prevent contaminants from
entering rainwater runoff.
(f) Any portable pad or retractable pad that
is stored in a manner to prevent the interception and subsequent runoff of
pesticide-containing material shall not be subject to the provisions of
subdivision (e) of this subrule.
(g) The mixing or loading of pesticides shall
not occur unless a primary shutoff mechanism is immediately accessible. In
addition, an emergency shutoff mechanism shall be located upstream from the
primary shutoff mechanism and shall be positioned to be fully operated within
30 seconds.
(h) The requirements of
this rule shall not apply to hand-held equipment.
(2) A pesticide-producing establishment that
is in compliance with the provisions of R 285.640.10 pertaining to operational
area containment is exempt from the provisions of this rule.
(3) An agricultural mixing or loading
facility that maintains a mixing and loading pad in accordance with the
provisions of this rule is exempt from maintaining a second mixing and loading
pad at a location where pesticides are mixed with anhydrous ammonia for a
period of not more than 60 days in any calendar year.
