Mich. Admin. Code R. 324.2005 - Secondary containment
Rule 5.
(1) Except
as may be authorized under subrule (5) of this rule, not later than 24 months
after the effective date of these rules, any on-land facility that has any
outdoor storage areas used to store liquid polluting materials in excess of a
threshold management quantity shall provide secondary containment structures
for those outdoor storage areas as required in subrule (2) of this
rule.
(2) Secondary containment
structures for liquids shall comply with all of the following provisions:
(a) Be constructed of materials that are
compatible with, and impervious to, or otherwise capable of containing, any
spilled, leaked, or discharged polluting materials so that the materials can be
recovered and so that polluting materials cannot escape directly or indirectly
to any public sewer system or to the surface waters or groundwaters of this
state.
(b) Provide a capacity that
is not less than 10% of the total volume of the tanks or containers within the
secondary containment structure or provide a capacity of 100% of the largest
single tank or container within the secondary containment structure, whichever
is larger.
(c) Allow surveillance
of the tanks or containers, the timely detection of any leaks and recovery of
any spillage, and the removal and proper disposal of any captured precipitation
so that the minimum required capacity is maintained at all times. Captured
precipitation may be removed by drainage through normally closed valves if all
of the following conditions are met:
(i) The
drainage is conducted under the direct supervision of qualified facility
personnel.
(ii) The valves are
secured closed at all times, except during precipitation removal.
(iii) The drainage is performed in full
compliance with all applicable local, state, and federal
requirements.
(3) All use areas and indoor storage areas
shall be designed, constructed, maintained, and operated to prevent the release
of polluting materials through sewers, drains, or otherwise directly or
indirectly into any public sewer system or to the surface or groundwaters of
this state.
(4) Polluting materials
in solid form shall be enclosed, covered, contained, or otherwise protected to
prevent run-on and any runoff, seepage, or leakage to any public sewer system
or to the surface or groundwaters of the state. Solid polluting materials shall
not be stored within 50 feet of a designated wetland or the shore or bank of
any lake or stream. Solid polluting material containment structures located
within a 100-year floodplain as defined by the federal flood disaster
protection act of 1973, 42 U.S.C. 4001 et seq., shall be designed and
constructed to remain effective during a 100-year flood.
(5) Alternate secondary containment, control,
or treatment systems other than those required in subrule (1) of this rule that
provide adequate protection may be used upon written approval of the
department. Requests for alternate secondary containment, control, or treatment
systems shall be submitted in writing to the chief of the department's waste
management division. The chief of the department's waste management division,
or his or her authorized delegee, shall either approve, approve with specifc
modifications, or disapprove a request for an alternate secondary containment,
control, or treatment system not more than 180 days after receipt.
