Cal. Code Regs. Tit. 22, § 66264.118 - Post-Closure Plan; Amendment of Plan
(a) Written Plan. The owner or operator of a
hazardous waste disposal unit shall have a written post-closure plan. In
addition, certain surface impoundments and waste piles from which the owner or
operator intends to remove or decontaminate the hazardous wastes at partial or
final closure are required by sections
66264.228(c)(1)(B)
and 66264.258(c)(1)(B)
to have contingent post-closure plans. The plan shall be submitted with the
permit application, in accordance with section
66270.14(b)(13)
of this division, or when otherwise requested by the Department. The plan shall
be approved by the Department as part of the permit issuance procedures under
chapter 21 of this division. In accordance with section
66270.32 of this division, the
approved post-closure plan will become a condition of any permit
issued.
(b) For each hazardous
waste management unit subject to the requirements of this section, the
post-closure plan shall identify the activities that will be carried on after
closure of each disposal unit and the frequency of these activities, and
include at least:
(1) a description of the
planned monitoring activities and frequencies at which they will be performed
to comply with articles 6, 11, 12, 13, 14, and 16 of this chapter during the
post-closure care period; and
(2) a
description of the planned maintenance activities, and frequencies at which
they will be performed, to ensure:
(A) the
integrity of the cap and final cover and other containment systems in
accordance with the requirements of articles 11, 12, 13, 14, and 16 of this
chapter; and
(B) the function of
the monitoring equipment in accordance with the requirements of articles 6, 11,
12, 13, 14, and 16 of this chapter; and
(3) the name, address, and phone number of
the person or office to contact about the hazardous waste disposal unit or
facility during the post-closure care period.
(c) Until final closure of the facility, a
copy of the approved post-closure plan and all revisions shall be kept at the
facility and furnished to the Department upon request, including request by
mail. After final closure, the person or office specified in section
66264.118(b)(3)
shall keep an updated and approved post-closure plan during the remainder of
the post-closure period.
(d)
Amendment of plan. The owner or operator shall submit a written notification of
or request for a permit modification to authorize a change in the approved
post-closure plan in accordance with the applicable requirements of chapters 20
and 21 of this division. The written notification or request shall include a
copy of the amended post-closure plan for review or approval by the Department.
(1) The owner or operator may submit a
written notification or request to the Department for a permit modification to
amend the post-closure plan at any time during the active life of the facility
or during the post-closure care period.
(2) The owner or operator shall submit a
written notification of or request for a permit modification to authorize a
change in the approved post-closure plan whenever:
(A) changes in operating plans or facility
design affect the approved post-closure plan, or
(B) there is a change in the expected year of
final closure, if applicable, or
(C) events which occur during the active life
of the facility or the post-closure care period, including partial and final
closures, affect the approved post-closure plan.
(3) The owner or operator shall submit a
written request for a permit modification at least 60 days prior to the
proposed change in facility design or operation, or no later than 60 days after
an unexpected event has occurred which has affected the post-closure plan. The
Department will approve, disapprove or modify this amended plan in accordance
with the procedures in chapters 20 and 21 of this division. In accordance with
section 66270.32 of this division, the
approved post-closure plan will become a permit condition.
(4) The Department shall modify or request
modifications to the plan under the conditions described in section
66264.118(d)(2)
or for other causes if deemed necessary to prevent threats to human health and
the environment. The owner or operator shall submit the modified plan no later
than 60 days after the Department's request. Any modifications requested by the
Department will be approved, disapproved, or modified in accordance with the
procedures in chapters 20 and 21 of this division.
