(COCs) in any environmental media fail to comply with any of the
following:
(a)
Applicable standards as determined from the generic
numerical standards in accordance with rule
3745-300-08
of the Administrative Code.

chapter.
(2)
Each complete exposure pathway for environmental media
determined in accordance with paragraph (F)(1) of rule
3745-300-07
of the Administrative Code shall comply with an applicable standard determined
in accordance with this chapter. When a complete exposure pathway does not
comply with an applicable standard, the volunteer shall implement a remedy in
accordance with this rule. Implementation of a remedy under the voluntary
action may be deferred or excluded, as applicable, for any complete exposure
pathway that is in compliance with paragraph (D) of this rule.
(3)
An institutional
control in the form of a use restriction, or activity and use limitation, as
applicable, shall be established in accordance with this rule to apply
applicable standards to a restricted land use, pursuant to paragraph (F)(5) of
rule

remedy employed at a property that does not yet meet applicable standards at
the time that a no further action letter is issued. Such remedial activities
shall achieve applicable standards within five years after the no further
action letter issuance date, inclusive of verification, or such other time
frame agreed to by the director in accordance with an operation and maintenance
agreement. In the case of any complete exposure pathway to indoor air due to
vapor exposure from environmental media, the indoor air applicable standards
shall be met prior to occupancy of the building.

If the remediation has not achieved applicable
standards upon issuance of the no further action letter, the no further action
letter shall demonstrate that the remediation is capable of attaining the
applicable standards, inclusive of verification, within five years after the no
further action letter issuance date or other time frame agreed upon by the
director in an operation and maintenance agreement, in accordance with this
rule. Until there is verification that the remediation meets applicable

(8)
Ground water use
limitations. Restrictions on the extraction or use of ground water for any
purpose, potable or otherwise, developed in accordance with paragraph (E)(2) of
rule
3745-300-10

The ground water
zone made subject to the use restriction has been demonstrated to have no
interconnection to an unrestricted ground water zone.
(b)
Selective use
restrictions shall be implemented for each ground water zone, as necessary, to
reliably restrict the use of each ground water zone, except the specific
permissible uses that are demonstrated to ensure the following:
(i)
The continued
protection of all ground water zones that otherwise meet unrestricted potable
use standards in accordance with paragraph (F) (4) of rule
3745-300-07
and paragraph (D) of rule
3745-300-10
of the Administrative Code.

(D)
Procedures to
address complete exposure pathways to off-property receptors that cannot be
remedied after a volunteer has applied diligent efforts. A volunteer may choose
to either defer or exclude an off-property complete exposure pathway in
accordance with the following:
(1)
Pathway deferral. When the volunteer has employed
diligent efforts to access an off-property area known or suspected to have a
complete exposure pathway but access has been denied, an off-property pathway
deferral shall be implemented by use of an operation and maintenance plan
included in the no further action letter. The releases of hazardous substances
or petroleum that are associated with the deferral of a complete exposure
pathway remain subject to the covenant not to sue issued for the property as
long as the pathway deferral obligations continue to be implemented in
accordance with any applicable operation and maintenance plan and agreement and
rule 3745-300-11 of the Administrative Code. Compliance with applicable
standards associated with the pathway are deferred until access to the
off-property area is attained, and the remedy is implemented and verified in
accordance with this chapter. To justify the pathway deferral, the volunteer
shall demonstrate that the following have been completed:
(a)
Off-property
receptors. Off-property areas where receptors are located and are different
from the voluntary action property as follows:
(i)
Identification of
current or reasonably anticipated off-property receptors that may be exposed to
COCs from the voluntary action property, in accordance with paragraph (E)(6) of
rule
3745-300-07
of the Administrative Code.

Identification
of current or reasonably anticipated exposure pathways to the off-property
receptors, in accordance with paragraph (F) of rule
3745-300-07
of the Administrative Code.

Communication to every owner of each receptor area
property of each complete exposure pathway, the applicable COCs, and the
potential risks with the COCs associated with the pathway
deferral.
(ii)
Explanation to every owner of each receptor area
property regarding the activities that might be reasonably employed to
investigate and remedy the pathway associated with the release from the
voluntary action property.
(iii)
Offer to pay
all costs associated with or to complete the assessment, and, as applicable,
remedial activities that are required to achieve applicable standards for the
complete exposure pathway related to releases from the voluntary action
property, including fair and reasonable compensation for repair of aesthetic
impacts to the off-property receptor area that result from the
activities.
(iv)
Offer to pay for all sampling costs after the
installation or implementation of a remedy to demonstrate the effectiveness of
the remedy.

to allow the volunteer the necessary access to complete assessment and, as
applicable, to conduct a reasonable remedy to achieve compliance with
applicable standards for the complete exposure pathway in accordance with this
chapter.
(vii)
Document, if applicable, any other reason that might
prevent access to complete assessment and installation of a reasonable remedy,
as necessary to comply with applicable standards for the complete exposure
pathway.

assistance. Within thirty days after the notice required in paragraph (D)(1)(c)
of this rule is sent, the volunteer shall contact Ohio EPA to seek assistance
with access to an off-property area, as follows:
(i)
After the notice
required in paragraph (D)(1)(c) of this rule is sent, contact Ohio EPA to seek
assistance to allow the volunteer access to an off-property area to assess or
install a reasonable remedy.
(ii)

Ohio EPA, provide to Ohio EPA, in a manner prescribed by Ohio EPA, the
following:
(a)
A summary of the diligent efforts and pathway deferral demonstration pursuant

behalf of the volunteer, the volunteer shall continue to evaluate the current
or reasonably anticipated exposure pathways to the off-property receptors in
accordance with paragraph (F) of rule 3745-300-07 of the Administrative Code to
determine compliance with applicable standards in accordance with paragraph (I)
of rule
3745-300-07
of the Administrative Code.
(iv)
A statement or
statements of costs incurred by Ohio EPA shall be sent to the volunteer after
Ohio EPA's assistance is complete. The volunteer shall pay the costs in full
within sixty days after receipt of the statement, pursuant to paragraph (E) of
rule
3745-300-03
of the Administrative Code.

Reimburse Ohio
EPA actual costs incurred to aid in communication with the owner of the
receptor area property, as described in paragraph (D)(1)(d) of this
rule.

not result in access to an off-property area, the timing for inclusion of
pathway deferral in an operation and maintenance plan and issuance of a no
further action letter shall occur as follows:
(i)
If Ohio EPA's
efforts to assist with access pursuant to paragraph (D) (1)(d) of this rule

access.
(iii)
If more than one hundred eighty days have passed since
the volunteer or Ohio EPA last contacted the owner of a receptor area property

provide a written invitation to the owner of the off-property receptor property
to reinitiate discussions about the deferred pathway and access to implement
the remedy needed to achieve applicable standards.
(b)
The notice shall
include the information required by paragraphs (D)(1)(c)(i) to (D)(1)(c)(iv) of

If the director determines that an extension of time is
necessary to properly consider the pathway exclusion request, the director may
extend the time to approve or deny the pathway exclusion request. If the
director extends the time to consider the pathway exclusion request, Ohio EPA
shall notify the volunteer and other interested persons of such
extension.
(h)
If the pathway exclusion request is approved by the
director, the approved pathway exclusion may be applied to a no further action
letter that is submitted to Ohio EPA with a request for a covenant not to
sue.
