Current through Register Vol. 48, No. 38, September 20, 2024
a) The owner or operator of any potential
tertiary source of groundwater contamination located wholly or partially within
the regulated recharge area must develop and implement a chemical substances
management system that must include the following:
1) a brief description of how the on-site
chemical substances are stored and used;
2) a potential release assessment and the
response procedures to be followed by the facility for notifying local
emergency response agencies;
3)
management measures that are employed to reduce the potential for releases;
and
4) training provided by the
Agency under Section 617.225.
b) The owner or operator of an existing
potential tertiary source of groundwater contamination located wholly or
partially within the regulated recharge area must:
1) Within 90 days after September 1, 2001,
register for the training required under Section 617.225; and
2) Within 120 days after September 1, 2001,
attend an Agency-sponsored training program required under Section
617.225 before the development
of the required chemical substances management plan (CSMP).
c) The owner or operator of an
existing potential tertiary source of groundwater contamination located wholly
or partially within the regulated recharge area must, within 180 days after the
training required under Section 617.225, develop a CSMP and make it available
on-site.
d) The chemical substances
management system for a new potential tertiary source must also include
secondary containment. Chemical substance storage areas regulated under this
Subpart must have a constructed or prefabricated containment system that is
operated as follows:
1) When not protected
from receiving precipitation, the constructed or prefabricated containment
system must have:
A) a minimum containment
volume of a 6-inch rain storm (a 25-year, 24-hour rain);
B) the capacity of the largest container or
tank; and
C) the volume displaced
by the bases of the other tanks located within the secondary containment
structure.
2) When
protected from receiving precipitation, the constructed or prefabricated
containment system must have a minimum containment volume of 100 percent of the
capacity of the largest container or tank, plus the volume displaced by the
bases of the other containers or tanks.
3) The owner or operator must prevent run-on
into the prefabricated or constructed secondary containment system unless the
collection system has sufficient excess capacity in addition to that required
in subsection (d)(1) to contain any run-on that might enter the constructed or
prefabricated containment system.
4) The owner or operator must remove spilled
or leaked material and accumulated precipitation from the sump or collection
area in a timely manner to prevent overflow of the collection system.
e) The owner or operator of a new
potential tertiary source of groundwater contamination located wholly or
partially within the regulated recharge area must:
1) register for the training required under
Section 617.225 at least 30 days before
the commencement of construction; and
2) attend an Agency sponsored training
program required under Section
617.225 within 60 days after
registration.
f) The
owner or operator of a potential primary or secondary source must review the
facility's chemical management practices and take any necessary actions to
ensure protection equivalent to subsection (a) or (d).
g) The owner or operator of a potential
tertiary source of groundwater contamination must do the following unless an
equivalent CSMP has been prepared and filed:
1) maintain a CSMP at the facility at all
times;
2) review the CSMP
annually;
3) clearly identify
changes in the CSMP;
4) provide a
copy of the initial Plan to the appropriate local fire department and police
response agency; and
5) make the
CSMP available for inspection by the public during normal operating
hours.
