(A) Facilities operating at or below their adjusted 2003 Allocation as of their 1994 compliance year.

    1. (i) The Facility Permit holder of major NOx sources may reclassify its major NOx sources to large NOx sources provided that (1) the facility's annual NOx emissions as properly reported in its 1994 compliance year APEP report are already at or below the level of its adjusted compliance year 2003 NOx Allocation. The adjusted compliance year 2003 NOx Allocation shall be the compliance year 2003 NOx Allocation as calculated pursuant to Rule 2002 subdivision (e) plus any compliance year 2003 NOx RTCs resulting from conversion of ERCs which the Facility Permit holder had applied to own by July 1, 1994 and has continuously owned, unless such RTCs have already been accounted for in the compliance year 2003 Allocation as established pursuant to Rule 2002 subdivision (e) and (2) it submits a complete application for NOx Super Compliant status on or before December 2, 1996. The Executive Officer will provisionally approve for purposes of paragraph (c)(5) such application if the Facility Permit holder has retired all NOx RTCs in excess of the facility's adjusted compliance year 2003 Allocation for each of the compliance years from the year of application submittal through the 2010 compliance year. The Facility Permit holder need not retire any RTCs (excluding converted ERCs) which are held by transfer pursuant to Rule 2007 paragraph (e)(2); however, such non-retired RTCs must be converted into RTC certificates pursuant to Rule 2007 subdivision (g), transferred to a different holder, or retired. For the purposes of this rule, converted ERCs shall mean NOx RTCs resulting from conversion of ERCs which the Facility Permit holder had applied to own by July 1, 1994 and has continuously owned.
    2. (ii) Final approval of NOx Super Compliant status shall be granted if the Executive Officer or designee approves the initial source test required by subparagraph (c)(4)(C) and the facility's total annual NOx emissions has not exceeded its adjusted compliance year 2003 Allocation.
    3. (B) Facilities not operating at or below their adjusted 2003 Allocation as of their 1994 compliance year.
    4. (i) On or before December 2, 1996 the facility Permit holder of major NOx sources may submit a complete application for NOx Super Compliant status. Such application must also include a complete application for permit modifications to install NOx emission reduction equipment or to make any other physical modifications to substantially reduce emissions from each major NOx source to be reclassified as a large NOx source. The Executive Officer shall deny the application for Super Compliant status unless the applicant demonstrates the proposed modifications would comply with all applicable District rules and would permanently reduce the facility's total annual NOx emissions to a level not to exceed its adjusted compliance year 2003 NOx Allocation as defined in clause (c)(4)(A)(i), would not result in any increases in the mass emissions of any other air contaminant or in emissions to any other media, and would not result in any increases in receptor concentrations of any air contaminant in excess of the values identified in Table A-2 of Rule 1303;
    5. (ii) Upon issuance of the permit to construct for the modification specified in clause (c)(4)(B)(i), the Executive Officer shall also issue a provisional approval of the facility's application for NOx Super Compliant status for purposes of paragraph (c)(5).
    6. (iii) Final approval of NOx Super Compliant status shall be granted if the following provisions are met:
      1. (I) An approved permit to operate has been issued for the modification specified in clause (c)(4)(B)(i);
      2. (II) The facility's total annual NOx emissions as reported in its APEP report are at a level at or below the facility's adjusted compliance year 2003 NOx Allocation on a permanent basis no later than the facility's 1998 compliance year;

(III) The Facility Permit holder has retired all NOx RTCs in excess of the facility's adjusted compliance year 2003 Allocation for each of the compliance years from the earlier of the facility's 1998 compliance year or the facility's first full compliance year with NOx Super Compliant Facility status through the facility's 2010 compliance year. The Facility Permit holder need not retire any RTCs (excluding converted ERCs as defined in clause (c)(4)(A)(i) which are held by transfer pursuant to Rule 2007 paragraph (e)(2); however, such non-retired RTCs must be converted into RTC certificates pursuant to Rule 2007 subdivision (g), transferred to a different holder, or retired; and
      4. (IV) The facility Permit holder has an approved initial source test as required under subparagraph (c)(4)(C).
      5. (C) The Facility Permit holder shall have initial NOx source tests conducted for each major NOx source to be reclassified as a large NOx source. The initial source tests shall be conducted pursuant to Appendix A, Chapter 5, Subdivisions A and D and shall be completed prior to January 1, 1998 for Cycle 1 facilities and prior to July 1, 1998 for Cycle 2 facilities. Additionally, the Facility Permit holder shall select an equipment-specific concentration limit for each major source which will be reclassified as a large NOx source. The concentration limits selected shall be consistent with the source test results and at a level adequate to allow continuous compliance and shall be enforceable through permit conditions.
      6. (D) Requirements to maintain Super Compliant status
      7. Super Compliant status is contingent upon the Facility Permit holder meeting at all times the following provisions:
    7. (i) Every major NOx source at a Super Compliant NOx facility which is reclassified as a large NOx source shall be source tested a minimum of once every six months in order to verify compliance with the equipment-specific concentration limit. The source test shall be conducted pursuant to Appendix A, Chapter 5, Subdivisions A and D and shall constitute the basis for assigning alternative emission factors. These source tests shall be conducted every two calendar quarters after the initial source test. If a source test is not conducted within three months after the required date, the facility shall no longer be considered Super Compliant, unless upon good cause the Executive Officer has granted a written extension of time. If the results of a source test indicate non-compliance with the concentration limit then the Facility Permit holder shall select a new concentration limit which is consistent with the source test results unless the Facility Permit holder demonstrates to the satisfaction of the Executive Officer or designee that no change is warranted. If all tests conducted pursuant to this paragraph over a two-year period comply with the equipment-specific concentration limit then the facility shall have the option of reducing the source test frequency to once every four quarters. If any test conducted on a four quarter cycle exceeds the concentration limit then the facility shall return to conducting source tests every two quarters.
    8. (ii) The facility's total annual NOx emissions, as reported in its APEP report, shall not exceed the facility's adjusted compliance year 2003 NOx Allocation. If there are such exceedances for two consecutive years or any three years, the facility shall no longer be considered Super Compliant.
  1. The Facility Permit holder of a facility which is provisionally approved for NOx Super Compliant status shall have the option for each major NOx source to be reclassified as a large NOx source, in lieu of following the procedures specified in clauses E(1)(d)(i), E(1)(d)(ii), and E(1)(d)(iii) of Appendix A Chapter 2, to monitor and report emissions pursuant to paragraph (d)(2). This option shall be available to the Facility Permit holder retroactively from July 1, 1995 if the complete application for NOx Super Compliant status is submitted on or before January 2, 1996, or retroactively from the date of application submittal if the complete application is submitted after January 2 and before December 3, 1996. If the facility is unsuccessful at obtaining designation as a NOx Super Compliant Facility then the procedures specified in clauses E(1)(d)(i), E(1)(d)(ii), and E(1)(d)(iii) of Appendix A Chapter 2 shall apply retroactively to each major NOx source reclassified as a large NOx source for which NOx emissions had been calculated pursuant to paragraph (d)(2) from the date the facility began monitoring and reporting major NOx source emissions as large NOx source emissions to the date a CEMS is installed and certified.
  2. After final approval of Super Compliant status, a Facility Permit holder may elect to discontinue its Super Compliant status and increase its annual Allocations above the level of its adjusted compliance year 2003 Allocation provided it first meets all of the following requirements:

(A) The Facility Permit holder submits an application to discontinue NOx Super Compliant status and to have all sources at the facility that were reclassified from major NOx sources to large NOx sources pursuant to paragraph (c)(4) permanently revert back to major NOx sources;

(B) The Facility Permit holder installs, operates, and certifies in compliance with Rule 2012 paragraphs (c)(2) and (c)(3) monitoring and reporting systems on each source at the facility that was reclassified from a major NOx source to a large NOx source pursuant to paragraph (c)(4); and

(C) The Facility Permit holder acquires, pursuant to Rule 2007, sufficient RTCs to ensure that the facility continuously operates in compliance with Rule 2004 subdivision (d).

  1. If a facility designated as a NOx Super Compliant Facility pursuant to paragraph (c)(4) exceeds its adjusted compliance year 2003 NOx Allocation, then the facility shall acquire, pursuant to Rule 2007, sufficient RTCs to cover such exceedance and shall be considered in violation of Rule 2004(d)(1).
  2. If the Executive Officer determines that a facility designated as a NOx Super Compliant Facility exceeds its adjusted compliance year 2003 NOx Allocation for two consecutive years or any three years, then that facility shall no longer be considered Super Compliant. If a facility loses its Super Compliant status pursuant to this paragraph or subparagraph (c)(4)(D), all sources at the facility that were reclassified from major NOx sources to large NOx sources pursuant to paragraph (c)(4) shall permanently revert back to major NOx sources and shall become subject to the monitoring and reporting requirements of paragraphs (c)(2) and (c)(3) according to the following schedule:

(A) Within one month from the end of the compliance year, submit a monitoring, reporting, and recordkeeping plan specifying the use of CEMS;

                      monitoring device which has been determined by
the 
                      Executive Officer or designee to be equivalent
to 
                      CEMS in relative accuracy, reliability, 
                      reproducibility and timeliness according to the
                      requirements set forth in Appendix A, Chapter 2. 
         

              (3) The Facility Permit holder of a major NOx source
shall:

                  (A) install, maintain and operate a reporting device
to
                      electronically report total daily mass emissions
of 
                      NOx and daily status codes to the District
Central 
                      NOx Station for each major NOx source.  Such
data 
                      shall be reported by 5:00 p.m., of the following
day.  
                      If the facility experiences a power, computer,
or
                      other system failure that prohibits the
reporting of 
                      total daily mass emissions of NOx and daily
status 
                      codes, the Facility Permit holder shall be
granted 
                      12 hours to submit the required report.  Between

                      July 1, 1995 and December 31, 1995, NOx
emissions 
                      after the 12-hour extension, shall be calculated
using 
                      interim reporting procedures set forth in
Appendix A, 
                      Chapter 2.  Starting January 1, 1996 and
thereafter, 
                      NOx emissions after the 12-hour extension shall
be 
                      calculated pursuant to the missing data
requirements 
                      set forth in Appendix A, Chapter 2; and
                
                  (B) submit Monthly Emissions Reports aggregating NOx
                      emissions from all major sources within 10 days 
                      following the end of each calendar month.  In
its 
                      Monthly Emissions Report the Facility Permit
holder 
                      may correct daily transmitted data for that
month 
                      provided such corrections are clearly identified
and
                      justified.

              (4) Super Compliant Facilities

                  (A) Facilities operating at or below their adjusted 
                      2003 Allocation as of their 1994 compliance
year.

                      (i)  The Facility Permit holder of major NOx
sources 
                           may reclassify its major NOx sources to
large 
                           NOx sources provided that (1) the
facility's 
                           annual NOx emissions as properly reported
in its 
                           1994 compliance year APEP report are
already at 
                           or below the level of its adjusted
compliance 
                           year 2003 NOx Allocation.  The adjusted 
                           compliance year 2003 NOx Allocation shall
be the
                           compliance year 2003 NOx Allocation as
calculated 
                           pursuant to Rule 2002(e) plus any
compliance 
                           year 2003 NOx RTCs resulting from
conversion of 
                           ERCs which the Facility Permit holder had
applied 
                           to own by July 1, 1994 and has continuously
owned, 
                           unless such RTCs have already been
accounted for 
                           in the compliance year 2003 Allocation as 
                           established pursuant to Rule 2002(c) and
(2) it 
                           submits a complete application for NOx
Super 
                           Compliant status on or before December 2,
1996.  
                           The Executive Officer will provisionally
approve 
                           for purposes of paragraph (c)(5) such
application 
                           if the Facility Permit holder has retired
all NOx
                           RTCs in excess of the facility's adjusted 
                           compliance year 2003 Allocation for each of
the 
                           compliance years from the year of
application 
                           submittal through the 2010 compliance year. 
The
                           Facility Permit holder need not retire any
RTCs 
                           (excluding converted ERCs) which are held
by 
                           transfer pursuant to Rule 2007 (e)(2);
however, 
                           such non-retired RTCs must be converted
into RTC
                           certificates pursuant to Rule 2007 (g), 
                           transferred to a different holder, or
retired.  
                           For the purposes of this rule, converted
ERCs 
                           shall mean NOx RTCs resulting from
conversion of
                           ERCs which the Facility Permit holder had
applied 
                           to own by July 1, 1994 and has continuously

                           owned.

                      (ii) Final approval of NOx Super Compliant
status 
                           shall be granted if the Executive Officer
or 
                           designee approves the initial source test 
                           required by subparagraph (c)(4)(C) and the
                           facility's total annual NOx emissions has
not 
                           exceeded its adjusted compliance year 
                           2003 Allocation.

                  (B) Facilities not operating at or below their
adjusted 
                      2003 Allocation as of their 1994 compliance
year.

                      (i)   On or before December 2, 1996 the facility

                            Permit holder of major NOx sources may
submit a 
                            complete application for NOx Super
Compliant 
                            status.  Such application must also
include a 
                            complete application for permit
modifications to 
                            install NOx emission reduction equipment
on the 
                            NOx sources and/or to make any other
physical 
                            modifications to NOx emitting equipment. 
The
                            Executive Officer shall deny the
application 
                            for Super Compliant status unless the
applicant 
                            demonstrates the proposed modifications
would 
                            comply with all applicable District rules
and
                            would permanently reduce the facility's
total 
                            annual NOx emissions to a level not to
exceed 
                            its adjusted compliance year 2003 NOx
Allocation 
                            as defined in clause (c)(4)(A)(i), would
not 
                            result in any increases in the mass
emissions of 
                            any other air contaminant or in emissions
to any 
                            other media, and would not result in any 
                            increases in receptor concentrations of
any air 
                            contaminant in excess of the values
identified 
                            in Table A-2 of Rule 1303;

                      (ii)  Upon issuance of the permit to construct

                            modification specified in clause
(c)(4)(B)(i), 
                            the Executive Officer shall also issue a 
                            provisional approval of the facility's 
                            application for NOx Super Compliant status
for 
                            purposes of paragraph (c)(5).

                      (iii) Final approval of NOx Super Compliant
status 
                            shall be granted if the following
provisions 
                            are met:

                            (I)   An approved permit to operate has
been 
                                  issued for the modification
specified in 
                                  clause (c)(4)(B)(i);

                            (II)  The facility's total annual NOx
emissions 
                                  as reported in its APEP report are
at a 
                                  level at or below the facility's
adjusted 
                                  compliance year 2003 NOx Allocation
on a
                                  permanent basis no later than the 
                                  facility's 1998 compliance year;

                            (III) The Facility Permit holder has
retired all 
                                  NOx RTCs in excess of the facility's

                                  adjusted compliance year 2003
Allocation 
                                  for each of the compliance years
from the 
                                  earlier of the facility's 1998
compliance 
                                  year or the facility's first full

facility's 
                                  2010 compliance year.  The Facility
Permit 
                                  holder need not retire any RTCs
(excluding 
                                  converted ERCs as defined in 
                                  clause (c)(4)(A)(i)) which are held
by 
                                  transfer pursuant to Rule 2007
(e)(2); 
                                  however, such non-retired RTCs must
be
                                  converted into RTC certificates
pursuant 
                                  to Rule 2007 (g), transferred to a 
                                  different holder, or retired; and

                            (IV)  The facility Permit holder has an
approved
                                  initial source test as required
under 
                                  subparagraph (c)(4)(C).

                  (C) The Facility Permit holder shall have initial
NOx 
                      source tests conducted for each major NOx source
to be 
                      reclassified as a large NOx source, as well as
of each 
                      NOx source or process unit included in the
application 
                      specified in clause (c)(4)(B)(i), if applicable. 
The 
                      initial source tests shall be conducted pursuant
to 
                      Appendix A, Chapter 5, Subdivisions A and D and
shall 
                      be completed prior to January 1, 1998 for Cycle
1 
                      facilities and prior to July 1, 1998 for Cycle 2

                      facilities.  Additionally, the Facility Permit
holder 
                      shall select an equipment-specific concentration
limit 
                      for each major source which will be reclassified
as a 
                      large NOx source.  The concentration limits
selected 
                      shall be consistent with the source test results
and 
                      at a level adequate to allow continuous
compliance 
                      and shall be enforceable through permit
conditions.

                  (D) Requirements to maintain Super Compliant status

                      Super Compliant status is contingent upon the
Facility
                      Permit holder meeting at all times the following

                      provisions:

                      (i)  Every major NOx source at a Super Compliant
NOx
                           facility which is reclassified as a large
NOx 
                           source shall be source tested a minimum of
once 
                           every six months in order to verify
compliance 
                           with the equipment-specific concentration
limit.  
                           The source test shall be conducted pursuant
to
                           Appendix A, Chapter 5, Subdivisions A and D
and 
                           shall constitute the basis for assigning 
                           alternative emission factors.  These source
tests 
                           shall be conducted every two calendar
quarters 
                           after the initial source test.  If a source
test 
                           is not conducted within three months after
the 
                           required date, the facility shall no longer
be 
                           considered Super Compliant, unless upon
good 
                           cause the Executive Officer has granted a
written 
                           extension of time.  If the results of a
source 
                           test indicate non-compliance with the
                           concentration limit then the Facility
Permit 
                           holder shall select a new concentration
limit 
                           which is consistent with the source test
results 
                           unless the Facility Permit holder
demonstrates to
                           the satisfaction of the Executive Officer
or 
                           designee that no change is warranted.  If
all 
                           tests conducted pursuant to this paragraph
over 
                           a two-year period comply with the 
                           equipment-specific concentration limit then
the 
                           facility shall have the option of reducing
the 
                           source test frequency to once every 
                           four quarters.  If any test conducted on a 
                           four quarter cycle exceeds the
concentration 
                           limit then the facility shall return to 
                           conducting source tests every two quarters.

                      (ii) The facility's total annual NOx emissions,
as
                           reported in its APEP report, shall not
exceed the 
                           facility's adjusted compliance year 2003
NOx 
                           Allocation.  If there are such exceedances
for 
                           two consecutive years or any three years,
the
                           facility shall no longer be considered
Super 
                           Compliant.

              (5) The Facility Permit holder of a facility which is
                  provisionally approved for NOx Super Compliant
status 
                  shall have the option of, in lieu of following the 
                  procedures specified in clauses E(1)(d)(i),
E(1)(d)(ii), 
                  and E(1)(d)(iii) of Appendix A Chapter 2, monitoring
and 
                  reporting emissions pursuant to paragraph (d)(2). 
This 
                  option shall be available to the Facility Permit
holder 
                  retroactively from July 1, 1995 if the complete 
                  application for NOx Super Compliant status is
submitted on 
                  or before January 2, 1996, or retroactively from the
date 
                  of application submittal if the complete application
is 
                  submitted after January 2 and before December 3,
1996.  If 
                  the facility is unsuccessful at obtaining
designation as 
                  a NOx Super Compliant Facility then the procedures 
                  specified in clauses E(1)(d)(i), E(1)(d)(ii), and 
                  E(1)(d)(iii) of Appendix A Chapter 2 shall apply 
                  retroactively to each major source for which NOx
emissions 
                  had been calculated pursuant to this paragraph
(c)(5) from 
                  the date the facility began monitoring and reporting
major 
                  NOx source emissions as large NOx source emissions
to the 
                  date a CEMS is installed and certified.

              (6) After final approval of Super Compliant status, a
Facility
                  Permit holder may elect to discontinue its Super
Compliant 
                  status and increase its annual Allocations above the
level 
                  of its adjusted compliance year 2003 Allocation
provided 
                  it first meets all of the following requirements:

                  (1) The Facility Permit holder submits an
application to
                      discontinue NOx Super Compliant status and to
have 
                      all sources at the facility changed from major
NOx 
                      sources to large NOx sources pursuant to 
                      paragraph (c)(4) permanently reclassified as
major
                      NOx sources;

                  (2) The Facility Permit holder installs, operates,
and
                      certifies in compliance with 2012(c)(2) and
2012(c)(3) 
                      monitoring and reporting systems on each source
at the 
                      facility changed from a major NOx source to a
large 
                      NOx source pursuant to paragraph (c)(4); and

                  (3) The Facility Permit holder acquires, pursuant to

                      Rule 2007, sufficient RTCs to ensure that the
facility 
                      continuously operates in compliance with Rule

          (f) Permit Conditions for Large Sources and Process Units

              (1) Starting January 1, 1994 for Cycle 1 facilities and
                  starting July 1, 1994 for Cycle 2 facilities,
calculations 
                  of mass emissions from each large source or process
unit 
                  shall be based upon the emission factor specified in

                  Rule 2002 - Allocations for Oxides of Nitrogen (NOx)
and 
                  Oxides of Sulfur (SOx).  The emission factor for
each 
                  large source or process unit will be specified in
the 
                  Facility Permit, and will remain valid unless
amended by 
                  the Executive Officer pursuant to paragraphs (f)(2),

                  (f)(3) or (f)(4).

              (2) On and after January 1, 1995 for Cycle 1 facilities
and
                  July 1, 1995 for Cycle 2 facilities, the Facility
Permit 
                  holder of a large source shall:

                  (A) comply at all times with an equipment-specific
NOx
                      concentration limit in ppm measured over any 
                      continuous 60 minutes as specified in the
Facility 
                      Permit for that source; according to the
requirements 
                      specified in Appendix A, Chapter 3 (large
sources); or

                  (B) establish an equipment-specific emission rate
that is
                      reliable, accurate and representative of that
source's 
                      emissions, according to the requirements
specified in 
                      Appendix A, Chapter 6.

              (3) A Facility Permit holder may apply to the Executive
Officer
                  or designee to amend the concentration limit or
equipment-
                  specific emission rate for a large source, or
emission 
                  factor or category-specific emission rate for a
process 
                  unit, in the Facility Permit, at any time.  If the 
                  applicant demonstrates to the Executive Officer or
designee 
                  that the alternative equipment-specific or 
                  category-specific emission rate is reliable,
accurate
                  and representative for the purpose of calculating
NOx 
                  emissions, the Executive Officer or designee will
amend 
                  the Facility Permit to incorporate the alternative 
                  equipment-specific or category-specific emission
rate.  No 
                  demonstration will be required to amend the Facility
Permit 
                  to incorporate the alternative concentration limit, 
                  provided the large source complies with that limit
in ppm 
                  over any continuous 60 minutes.  The alternative 
                  concentration limit or equipment-specific emission
rate for 
                  a large source, or the alternative emission factor
or 
                  category-specific emission rate for a process unit,
shall 
                  take effect prospectively from the date the Facility
Permit 
                  is amended.

              (4) The Executive Officer or designee may amend the
Facility
                  Permit at any time to specify an alternative 
                  equipment-specific emission rate for a large source,
or an 
                  alternative emission factor or category-specific
emission 
                  rate for a process unit, if the alternative emission
rate 
                  or emission factor is determined to be more
reliable, 
                  accurate, or representative of that source's or
unit's 
                  emissions than the previous emission factor, or 
                  concentration limit or emission rate specified in
the 
                  Facility Permit.  The alternative concentration
limit or 
                  equipment-specific emission rate for a large source,
or 
                  alternative emission factor or category-specific
emission 
                  rate for a process unit shall take effect
prospectively 
                  from the date the Facility Permit is amended.
