Conn. Agencies Regs. § 22a-354i-9 - Best management practices for regulated activities
(a) Every regulated activity shall be
conducted in accordance with the following:
(1) Hazardous materials may be stored above
ground within an aquifer protection area only in accordance with the following
conditions:
(A) hazardous material shall be
stored in a building or under a roof that minimizes storm water entry to the
hazardous material storage area, except that a roof is not required for a bulk
storage facility as defined in section
22a-354i-1(6)
of the Regulations of Connecticut State Agencies,
(B) floors within a building or under a roof
where hazardous material may be stored shall be constructed or treated to
protect the surface of the floor from deterioration due to spillage of any such
material,
(C) a structure which may
be used for storage or transfer of hazardous material shall be protected from
storm water run-on, and ground water intrusion,
(D) hazardous material shall be stored within
an impermeable containment area which is capable of containing at least the
volume of the largest container of such hazardous material present in such
area, or 10% of the total volume of all such containers in such area, whichever
is larger, without overflow of released hazardous material from the containment
area,
(E) hazardous material shall
not be stored with other hazardous materials that are incompatible and may
create a hazard of fire, explosion or generation of toxic substances,
(F) hazardous material shall be stored only
in a container that has been certified by a state or federal agency or the
American Society of Testing Materials as suitable for the transport or storage
of such material,
(G) hazardous
material shall be stored only in an area that is secured against unauthorized
entry by the public, and
(H) the
requirements of this subdivision are intended to supplement, and not to
supersede, any other applicable requirements of federal, state, or local law,
including applicable requirements of the Resource Conservation and Recovery Act
of 1976, as amended;
(2)
no person shall increase the number of underground storage tanks used to store
hazardous materials;
(3) an
underground storage tank used to store hazardous materials shall not be
replaced with a larger tank unless (A) there is no more than a 25% increase in
volume of the larger replacement tank, and (B) the larger replacement tank is a
double-walled tank with co-axial piping, both meeting new installation
component standards pursuant to 22a-449(d)-1(e) and 22a-449(d)-102 of the
Regulations of Connecticut State Agencies, and with interstitial
monitoring;
(4) no person shall
use, maintain or install floor drains, dry wells or other infiltration devices
or appurtenances which allow the release of waste waters to the ground, unless
such release is permitted by the Commissioner in accordance with sections
22a-430
or
22a-430b
of the Connecticut General Statutes; and
(5) a materials management plan shall be
developed and implemented in accordance with the following:
(A) A materials management plan shall
contain, at a minimum, the following information with respect to the subject
regulated activity:
(i) A pollution prevention
assessment consisting of a detailed evaluation of alternatives to the use of
hazardous materials or processes and practices that would reduce or eliminate
the use of hazardous materials, and implementation of such alternatives where
possible and feasible,
(ii) a
description of any operations or practices which may pose a threat of pollution
to the aquifer, which shall include the following:
(a) a process flow diagram identifying where
hazardous materials are stored, disposed and used, and where hazardous wastes
are generated and subsequently stored and disposed,
(b) an inventory of all hazardous materials
which are likely to be or will be manufactured, produced, stored, utilized or
otherwise handled, and
(c) a
description of waste, including waste waters generated, and a description of
how such wastes are handled, stored and disposed,
(iii) the name, street address, mailing
address, title and telephone number of the individual(s) responsible for
implementing the materials management plan and the individual(s) who should be
contacted in an emergency,
(iv) a
record-keeping system to account for the types, quantities, and disposition of
hazardous materials which are manufactured, produced, utilized, stored, or
otherwise handled or which are discharged or emitted; such record-keeping
system shall be maintained at the subject facility and shall be made available
thereat for inspection during normal business hours by the Commissioner and the
municipal aquifer protection agency, and
(v) an emergency response plan for responding
to a release of hazardous materials. Such plan shall describe how each such
release could result in pollution to the underlying aquifer and shall set forth
the methods used or to be used to prevent and abate any such a
release;
(B) when a
materials management plan is required under either section
22a-354i-7(d)
or
22a-354i-8(c),
such materials management plan shall be completed and certified by a
professional engineer or a certified hazardous materials manager, or, if the
facility where the regulated activity is conducted has received and maintained
an ISO 14001 environmental management system certification, then the registrant
may complete and certify the materials management plan; and
(C) the materials management plan shall be
maintained at the subject facility and shall be made available thereat for
inspection during normal business hours by the Commissioner and the municipal
aquifer protection agency.
(b) The development and implementation of a
storm water management plan shall be required for regulated activities in
accordance with sections
22a-354i-7(d)
and
22a-354i-8(c)
of the Regulations of Connecticut State Agencies, as follows:
(1) A storm water management plan shall
assure that storm water run-off generated by the subject regulated activity is
(i) managed in a manner so as to prevent pollution of ground water, and (ii)
shall comply with all of the requirements for the General Permit of the
Discharge of Storm Water associated with a Commercial Activity issued pursuant
to section
22a-430b
of the Connecticut General Statutes; and
(2) upon approval by the Commissioner or the
municipal aquifer protection agency, as appropriate, the storm water management
plan shall be enforceable by the Commissioner or such agency, as
appropriate.
