(a) Eligible Facilities. Offsets shall only be used by the owners and operators of facilities that
meet criteria (1) and (2) below.
(1) The request to offset air quality impacts using ERCs shall be included in an application for
a PSD permit.
(2) The facility must be located within 100 miles of the facility that generated the applicable
ERCs unless a determination is made in accordance with (B) below.
(A) The measurement to determine the distance between the facility using ERCs and the
facility that generated the ERCs shall be based on the center point of each facility.

(B) DEQ may allow a facility to use ERCs generated at a facility that is farther than 100
miles away if:
(i) In the judgment of DEQ, such an allowance is appropriate;
(ii) The facility applying to use ERCs provides a reasonable justification for such an
exception; and
(iii) The justification is supported by air quality modeling, prevailing weather patterns,
or other criteria specified by the Director.
(b) Application. To be eligible to use ERCs to offset project emission increases under the PSD
program, an ERC user must submit an application that meets criteria (1) through (4) below.
(1) The ERCs used to offset project emission increases must offset all project emission
increases for the new major stationary source construction or new major modification to an
existing source.
(2) In addition to offsetting all project emission increases, the applicant must extinguish an
additional 10% of the project emission increases to ensure that the project results in an
aggregate reduction in airshed emissions.
(3) The ERC user must submit an administratively complete application for a PSD construction
permit in accordance with Parts 5 and 7 of OAC 252:100-8.
(4) The ERC user must submit, along with the application, a document confirming the
acquisition of the desired ERCs.
(c) Administrative Review. Following receipt of an eligible ERC user’s application for the use of
ERCs in offsetting project emission increases, DEQ shall verify the information contained in the
application and, if appropriate, approve the issuance of a PSD construction permit that authorizes
the project and the use of the offsetting emissions.
(1) DEQ may request additional information from the eligible ERC user if the application for
project authorization is incomplete or otherwise deviates from the requirements detailed in this
subsection.
(2) As part of its review of an eligible ERC user application, DEQ shall determine if an ERC
may still be considered surplus.
(d) Public Review. In accordance with the requirements of OAC 252:4-7-33(b) and OAC 252:4-
7-34(a), any permit that extinguishes ERCs to offset air quality impacts shall be required to
undergo either Tier II or Tier III public participation.
(e) Acquisition of ERCs. The eligible ERC user is responsible for contracting with one or more
ERC generators, or another entity that has obtained ERCs, to acquire a sufficient quantity of ERCs
to offset 110% of project emission increases.
(1) DEQ shall ensure that all of the following requirements are met before issuing a PSD permit
where air quality impacts are offset by the extinguishment of the required quantity of ERCs.
Any ERC used to offset air quality impacts must be confirmed to be surplus on the date the
draft PSD permit is published for public review in accordance with OAC 252:4-7 and state
review in accordance with OAC 252:100-8-8.
(A) Prior to publication of the draft PSD permit, DEQ must confirm that any ERC listed in
the ERC registry that will be used to offset air quality impacts remains surplus.
(B) If, after performing the determination, DEQ concludes that only a portion of the ERCs
remain surplus, the ERC user shall acquire sufficient surplus ERCs to offset 110% of
project emission increases.
(2) The ERC user must have acquired all necessary ERCs before the PSD permit may be issued.

(3) DEQ shall determine that the permit has undergone all required public notice and public
participation requirements required in OAC 252:4-7-33(b) or OAC 252:4-7-34(a) as
appropriate.
(f) Extinguishment of ERCs. The PSD permit shall specify the date(s) and/or the action(s) which
will trigger the extinguishment of the ERCs by DEQ. The PSD permit holder shall confirm in
writing that these actions have taken place, as required in the permit, and DEQ shall extinguish the
ERCs as required and shall update the ERC registry.
