Ohio Admin. Code 3745-55-44 - Cost estimate for post-closure care
(A) The owner or operator of a disposal
surface impoundment, disposal miscellaneous unit, land treatment unit, or
landfill unit, or of a surface impoundment or waste pile that is required under
rules
3745-56-28
and
3745-56-58
of the Administrative Code to prepare a contingent closure and post-closure
plan, shall have a detailed written estimate, in current dollars, of the annual
cost of post-closure monitoring and maintenance of the facility in accordance
with the applicable postclosure requirements in rules
3745-55-17
to
3745-55-20,
3745-56-28,
3745-56-58,
3745-56-80,
3745-57-10,
and
3745-57-93 of
the Administrative Code.
(1) The post-closure
cost estimate shall be based on the costs to the owner or operator of hiring a
third party to conduct post-closure care activities. A "third party" is a party
who is neither a parent nor a subsidiary of the owner or operator (see
definition of "parent corporation" in rule
3745-55-41 of the
Administrative Code).
(2) The
post-closure cost estimate is calculated by multiplying the annual post-closure
cost estimate by the number of years of post-closure care required in rule
3745-55-17
of the Administrative Code.
(B) During the active life of the facility,
the owner or operator shall adjust the post-closure cost estimate for inflation
within sixty days prior to the anniversary date of the establishment of the
financial instruments used to comply with rule
3745-55-45
of the Administrative Code. For owners or operators using the financial test or
corporate guarantee, the post-closure cost estimate shall be updated for
inflation within thirty days after the close of the firm's fiscal year and
before the submittal of updated information to the director as specified in
paragraph (F)
(F)(5) of rule
3745-55-45
of the Administrative Code. The adjustment may be made by recalculating the
postclosure cost estimate in current dollars or by using an inflation factor
derived as specified in
40 CFR
264.144(b).
(1) The first adjustment is made by
multiplying the post-closure cost estimate by the inflation factor. The result
is the adjusted post-closure cost estimate.
(2) Subsequent adjustments are made by
multiplying the latest adjusted post-closure cost estimate by the latest
inflation factor.
(C)
During the active life of the facility, the owner or operator shall revise the
post-closure cost estimate within thirty days after the director has approved
the request to modify the post-closure plan if the change in the post-closure
plan increases the cost of postclosure care. The revised post-closure cost
estimate shall be adjusted for inflation as specified in paragraph (B) of this
rule.
(D)
The
During the
operating life of the facility, the owner or operator shall keep
the following at the facility
during the operating life of the facility:
the latest post-closure cost estimate prepared in accordance with paragraphs
(A) and (C) of this rule and, when this estimate has been adjusted in
accordance with paragraph (B) of this rule, the latest adjusted post-closure
cost estimate.
(E) A copy of the
facility's current, detailed post-closure cost estimate prepared and maintained
in accordance with paragraphs (A) and (B) of this rule shall be submitted
annually to the director.
(1) For owners or
operators using a financial mechanism other than the financial test, such
submittal of the post-closure cost estimate to the director shall be made
within sixty days following
after a
revision or update to the estimate made in accordance with paragraph (B) of
this rule.
(2) For owners or
operators using a financial test, such submittal of the post-closure cost
estimate to the director shall be made within ninety days after the close of
the firm's fiscal year following
after a revision or update to the estimate made in
accordance with paragraph (B) of this rule.
