Technical Support Document: Corrections of deficiencies in Indiana CAIR
abbreviated SIP revision dated 09/20/07

	The following corrections of deficiencies need to be made in
Indiana’s CAIR abbreviated SIP revision dated 09/20/07: 

CAIR NOx Ozone Season trading rule 

1. In 326 IAC 24-3-1, Indiana needs to revise, in subsection (b),
“CAIR NOx ozone season units as follows:” to read “CAIR NOx ozone
season units under subsection 1(a)(1) or (3)” and revise, in
subsections (b)(1), (2), and (3), “under subsection (a)” to read
“under subsection (a)(1) or (3)”. 

2. In 326 IAC 24-3-2, Indiana needs to: 

a. revise the definition of commence operation to add 

“(D) Notwithstanding clauses (A), (B), and (C) of this definition, and
solely for purposes of Section 11, for a unit that is not a large
affected unit under Section 2(49)(A) or (B) on the later of November 15,
1990 or the date the unit commences operation as defined in paragraph
(i) of this definition and that subsequently becomes a large affected
unit under Section 2(49)(A) or (B), the unit's date for commencement of
operation shall be the date on which the unit becomes a large affected
unit under Section (2)(49)(A) or (B).  

(E)  For a unit with a date of commencement of operation as defined in
clause (D) of this definition and that subsequently undergoes a physical
change, other than replacement of the unit by a unit at the same source,
such date shall remain the date of commencement of operation of the
unit, which shall continue to be treated as the same unit.

(F) For a unit with a date for commencement of operation as defined in
clause (D) of this definition and that is subsequently replaced by a
unit at the same source, e.g., repowered, such date shall remain the
replaced unit's date of commencement of operation, and the replacement
unit shall be treated as a separate unit with a separate date for
commencement of operation as defined in clauses (A) through (F) of this
definition as appropriate.”

b. add the definition of electricity for firm sale to the electric grid
to read:

“Electricity for firm sale to the electric grid means electricity for
sale where the capacity involved is intended to be available at all
times during the period covered by a guaranteed commitment to deliver,
even under adverse conditions.”  

c. revise the definition of fossil-fuel-fired to read “means, with
regard to a unit:

(A) Except as provided in clause (B), combusting any amount of fossil
fuel in any calendar year; and

(B) Solely for purposes of applying the definition of “Large affected
unit”, the combustion of fossil fuel, alone or in combination with any
other fuel, under any of the following scenarios:

(i) fossil fuel actually combusted comprises more than fifty percent
(50%) of the annual heat input on a British thermal unit (Btu) basis
during any year starting in 1995.  If a unit had no heat input starting
in 1995, during the last year of operation of the unit prior to 1995; or
 

(ii) fossil fuel is projected to comprise more than fifty percent (50%)
of the annual heat input on a Btu basis during any year, provided that
the unit shall be fossil fuel-fired as of the date, during the year,
that the unit begins combusting fossil fuel.”

d. revise the definition of large affected unit to add, after clause
(B):

“(C) For units other than cogeneration units commencing operation:

(i) before January 1, 1997, a unit serving a generator during 1995 or
1996 that had a nameplate capacity greater than twenty-five (25)
megawatts and produced electricity for sale under a firm contract to the
electric grid;

(ii) on or after January 1, 1997, and before January 1, 1999, a unit
serving a generator during 1997 or 1998 that had a nameplate capacity
greater than twenty-five (25) megawatts and producing electricity for
sale under a firm contract to the electric grid; or

(iii) on or after January 1, 1999, a unit serving a generator at any
time that has a nameplate capacity greater than twenty-five (25)
megawatts and produces electricity for sale.

(D) For cogeneration units commencing operation:

(i) before January 1, 1997, a unit serving a generator during 1995 or
1996 that had a nameplate capacity greater than twenty-five (25)
megawatts and failing to qualify as an unaffected unit for 1995 or 1996
under the acid rain program;

(ii) in 1997 or 1998, a unit serving a generator during 1997 or 1998
with a nameplate capacity greater than twenty-five (25) megawatts and
failing to qualify as an unaffected unit for 1997 or 1998 under the acid
rain program; or

(iii) on or after January 1, 1999, a unit serving at any time as a
generator with a nameplate capacity greater than twenty-five (25)
megawatts and failing to qualify as an unaffected unit under the acid
rain program for any year.”

e. revise the definition of unit to read “means:

(A) Except as provided in clause (B), a stationary, fossil-fuel-fired
boiler or combustion turbine or other stationary fossil-fuel-fired
combustion device; and

(B) Solely for purposes of applying the definition of “Large affected
unit”, a fossil fuel-fired:

(i) stationary boiler;

(ii) combustion turbine; or

(iii) combined cycle system.”
