(A) The following provisions apply to NSR
projects at existing emissions units at a
major stationary source (other than
NSR projects at a
stationary source with a
PAL) in circumstances where there is
a
reasonable possibility as defined in rule
3745-31-01 of the Administrative
Code that
a
an NSR project that is not part of a
major
modification may result in a
significant emissions increase and the owner or
operator elects to use the method specified in paragraph
(GGGGG)
(P)(28) of rule
3745-31-01 of the Administrative
Code for calculating
projected actual emissions.
(1) Before beginning actual
construction of
the
NSR project, the owner or operator shall document and maintain a record of
the following information:
(a) A description
of the NSR project.
(b)
Identification of the emissions
unit(s)
unit whose emissions of a
regulated NSR pollutant
could be affected by the
NSR project.
(c) A description of the applicability test
used to determine that the
NSR project is not a
major modification for any
regulated NSR pollutant, including the
baseline actual emissions, the
projected
actual emissions, the amount of "could have accommodated" emissions excluded
under paragraph
(GGGGG)(1)(c)
(P)(28)(c) of rule
3745-31-01 of the Administrative
Code and an explanation for why such amount was excluded, and any netting
calculations, if applicable.
(2) Before beginning actual
construction,
regardless of whether the owner or operator determines there is a
reasonable
possibility that
a
an NSR project that is not part of a
major
modification may result in a
significant emissions increase, the owner or
operator shall provide a copy of the information set out in paragraph (A)(1) of
this rule to the
director for any of the following:
(a) New or modified emissions units where the
sum of the
federally enforceable potential to emit of the new or modified
emissions units associated with the
NSR project prior to the issuance of the
NSR project's permit-to-
install is greater than any one of the
significant
levels found in the
significant definition of rule
3745-31-01 of the Administrative
Code.
(b) Any emissions unit that
is an existing electric utility steam generating unit.
(c) Unless required elsewhere in this rule,
nothing in this paragraph shall be construed to require the owner or operator
of such emissions unit to obtain any determination from the director before
beginning actual construction.
(3) The owner or operator shall monitor the
emissions of any regulated NSR pollutant that could increase as a result of the
NSR project and that is emitted by any emissions units identified in paragraph
(A)(1)(b) of this rule; and calculate and maintain a record of the annual
emissions, in tons per year on a calendar year basis, for a period of five
years following resumption of regular operations after the change, or for a
period of ten years following resumption of regular operations after the change
if the NSR project increases the design capacity or potential to emit of that
regulated NSR pollutant at such emissions unit.
(4) If
the emissions unit is an existing
electric utility steam generating unit, the owner or operator shall submit a
report to the
director within sixty days after the end of each year during
which records
must
shall be generated under paragraph (A)(3) of this rule
setting out
the emissions unit's annual emissions during the year that preceded
submission of the report.
(5) If
the emissions unit is an
existing emissions unit other than an
electric utility
steam generating unit, the owner or operator shall submit a report to the
director if the annual emissions, in tons per year, from the
NSR project
identified in paragraph (A)(1) of this rule, exceed the
baseline actual
emissions (as documented and maintained pursuant to paragraph (A)(1)(c) of this
rule
,
) by a
significant amount for that
regulated NSR pollutant, and if such emissions
differ from the preconstruction projection as documented and maintained
pursuant to paragraph (A)(1)(c) of this rule. Such report shall be submitted to
the
director within sixty days after the end of such year. The report shall
contain the following:
(a) The name, address
and telephone number of the major stationary source.
(b) The annual emissions as calculated
pursuant to paragraph (A)(3) of this rule.
(c) Any other information that the owner or
operator wishes to include in the report (e.g., an explanation as to why the
emissions differ from the preconstruction projection).
(6) A "reasonable possibility" under
this rule occurs when the owner or operator calculates the project to result in
either:
(a) A projected actual emissions
increase of at least fifty per cent of the amount that is a "significant
emissions increase," as defined in rule 3745-31-01 of the Administrative Code
(without reference to the amount that is a significant net emissions increase),
for the regulated NSR pollutant.
(b) A projected actual emissions
increase that, added to the amount of emissions excluded under paragraph
(GGGGG)(3) of rule 3745-31-01 of the Administrative Code, sums to at least
fifty per cent of the amount that is a "significant emissions increase," as
defined under paragrapgh (WWWWW) of rule 3745-31-01 of the Administrative Code
(without reference to the amount that is a significant net emissions increase),
for the regulated NSR pollutant. For a project for which a reasonable
possibility occurs only within the meaning of paragraph (A)(6)(b) of this rule,
and not also within the meaning of paragraph (A)(6)(a) of this rule, then
provisions under paragraphs (A)(2) to (A)(5) of this rule do not apply to the
project.
