(Amended January 7, 2005)

2011 - 2 (F) any SO x source or process unit elected by the Facility Permit holder or required by the Executive Officer or designee to be monitored with a CEMS or equivalent monitoring device; (G) any SO xsource or process unit for which SO xemissions reported pursuant to Rule 301 - Permit Fees, were equal to or greater than 10 tons per year for any calendar year between 1987 to 1991, inclusive, excluding any SO xsource or process unit which has
reduced SO xemissions to below 10 tons per year prior to January 1, 1994. (2) The Facility Permit holder of a major SO xsource shall: (A) install, maintain, and operate a direct monitoring device for each major SO xsource to continuously measure the concentration of
SO xemissions or fuel sulfur content and all other applicable variables specified in Table 2011-1 and Appendix A, Chapter 2, Table 2-A; or (B) install, maintain, and operate an alternative monitoring device which has been determined by th e 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. (C) The operating requirements specified in subparagraph (c)(2)(A) or (c)(2)(B) shall not apply during any time period not to exceed 96 hours provided that all of the following are met: (i) the Facility Permit holder reports emissions as specified in Appendix A; (ii) the direct monitoring device has been either: (I) shut down for maintenance performed pursuant to the facility’s Quality Assurance and Quality Control Program or (II) damaged in a fire or mechanical or electrical failure caused by circumstances beyond the Facility Permit holder’s control; andRule 2011 (Cont.) (Amended January 7, 2005)

2011 - 3 (iii) Whenever the monitoring device is non-operational for more than 24 hours, the Facility Permit holder shall submit a report to the Executive Officer within 96 hours after the device becomes non-operational. Such report shall include information as prescribed by the Executive Officer including at a mi nimum the cause of theshutdown, the time the monitoring device became nonoperational, the time or estimated time the monitoring device returned to normal operation, and the maintenance performed or corrective and preventative actions taken to prevent future non-operational conditions.
If the source for which the CEMS is certified to monitor is not operating when the CEMS is in maintenance or being repaired,
and either the flow or concentr ation monitor is properly operating, and clauses (c)(2)(C)(i) and (c)(2)(C )(ii) are met, then the above time period shall be extended for an additional 96 hours. (3) The Facility Permit holder of a major SO xsource shall: (A) install, maintain, and operate a reporting device to electronically report to the District Central SO xStation for each major SO x source: total daily mass emissions of SO xand daily status codes.
Such data shall be transmitted by 5:00 p.m. of the following day. If the facility experiences a power, computer, or other system failure that prevents the reporti ng of total daily mass emissions of
SO xand daily status codes, th e Facility Permit holder shall be granted 24 hours to submit the required report. Between July 1, 1995 and December 31, 1995, SO xemissions after the 24-hour extension, shall be calculated using interim reporting procedures set forth in Appendix A, Chapte r 2. Starting January 1, 1996 and thereafter, SO xemissions after the 24-hour extension shall be calculated pursuant to the missing data requirements set forth in Appendix A, Chapter 2. For each major SO xsource opting to comply with subparagraph (c)(10), reports of SO xmass emissions shall be electronically filed on a monthly instead of daily basis;
andRule 2011 (Cont.) (Amended January 7, 2005)

2011 - 4 (B) submit Monthly Emissions Report aggregating SO xemissions from all major sources within 15 days following the end of each
calendar month. In its Monthl y Emissions Report, the Facility Permit holder may correct daily transmitted data for that month, provided such corrections are clearly identified and justified. (C) Notwithstanding subparagraph (c )(3)(A), starting May 11, 2001 if a power, computer, or other system failure precludes the Facility Permit holder from reporting total daily mass emissions of SO x and daily status codes by 5:00 p.m., the Facility Permit holder shall be granted 96 hours to submit the required report provided that the raw data as obtained by the direct monitoring device is stored at the facility. SO xemissions reported after the 96-hour extension shall be calculated pursuant to the missing data requirements set forth in Appendix A, Chapter 2. The provisionsof this subparagraph shall be limited to no more than three nonconsecutive occurrences per compliance year. (D) The requirement of calculati ng emissions using Missing Data Procedures under subparagraph (c)(3)(A) shall not apply if the failure to report the total daily mass emissions of SO xand daily
status codes is due to a demons trated failure at the District’s Central Station preventing it from receiving the data. The Facility
Permit holder shall submit the report within 48 hours of the problem being corrected, provided th at the raw data as obtained by the direct monitoring device is stored at the facility. SO x emissions reported after the 48-hour extension shall be calculated pursuant to the missing data requirements set forth in Appendix A, Chapter 2. (4) Super Compliant Facilities (A) Facilities operating at or below their adjusted 2003 Allocation as of their 1994 compliance year.Rule 2011 (Cont.) (Amended January 7, 2005)

2011 - 5 (i) The Facility Permit holder of major SO xsources may reclassify its major SO xsources to SO xprocess units provided that (1) the facility's annual SO xemissions as properly reported in its 1994 compliance year APEP report are already at or below the level of its adjusted compliance year 2003 SO xAllocation. The adjusted compliance year
2003 SO xAllocation shall be the compliance year 2003
SO xAllocation as calculated pursuant to Rule 2002 subdivision (e) plus any compliance year 2003 SO xRTCs resulting from conversion of ERCs which the Facility Permit holder had applied to own by July 1, 1994 and has continuously owned, unless suchRTCs 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 SO xSuper Compliance 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 SO xRTCs 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
SO xRTCs 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 SO xSuper Compliant status shall be granted if the Executive Offi cer or designee approves the initial source test required by subparagraph (c)(4)(C) and the facility's total annual SO xemissions has not exceeded its adjusted compliance year 2003 Allocation.Rule 2011 (Cont.) (Amended January 7, 2005)

2011 - 6 (B) Facilities not operating at or belo w their adjusted 2003 Allocation as of their 1994 compliance year. (i) On or before December 2, 1996 the facility Permit holder of major SO xsources may submit a complete application
for SO xSuper Compliant status. Such applications must also include a complete application for permit
modifications to install SO xemission reduction equipment or to make any other physical modifications to substantially reduce emissions from each major SO x source to be reclassified as a SOx process unit. 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 SO xemissions to a level not to exceed its adjusted compliance year 2003 SO xAllocation 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 A2 of Rule 1303; (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 SO xSuper Compliant status for purposes of paragraph (c)(5). (iii) Final approval of SO xSuper 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 SO xemissions as reported in its APEP report are at a level at or below the facility's adjusted compliance year 2003
SO xAllocation on a permanent basis no later than the facility's 1998 compliance year;Rule 2011 (Cont.) (Amended January 7, 2005)

2011 - 7 (III) The Facility Permit holder has retired all SO xRTCs 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 firs t full compliance year with
SO xSuper 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 (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 source tests conducted to establish an equipment specific emission rate, for each major
source to be reclassified as a SO xprocess unit, pursuant to Appendix A, Chapter 4, Subdivisi on D prior to January 1, 1998 for Cycle 1 facilities and prior to July 1, 1998 for Cycle 2 facilities. In lieu of an equipment specific emission rate, the Executive Officer may approve an equipment specific concentration limit if the Facility Permit holder demonstrates to the satisfaction of the Executive Officer that there are no measurable operating parameters to establish an accurate equipment specific emission rate. The Facility Permit holder shall have initial source tests conducted in accordance with test methods listed under Rule 2011, Appendix A, Chapter 4, Subdivision A - Test Methods, to establish emission levels of the source. The Facility Permit holder shall select an equipment-specific concentration limit for each major source which will be reclassified as a SO xprocess unit. 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.Rule 2011 (Cont.) (Amended January 7, 2005)

2011 - 8 (i) For facilities seeking Super Compliant status pursuant to subparagraph (c)(4)(A), the Facility Permit holder may use
the concentration limit to determine emissions retroactive to the date of provisional approval of the application for
SO xSuper Compliant status. (ii) For facilities seeking Super Compliant status pursuant to subparagraph (c)(4)(B), the Facility Permit holder may use
the concentration limit to determine emissions retroactive to the date of completion of modification. (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 SO xsource at a Super Compliant SO xfacility
which is reclassified as a SO xprocess unit with an approved equipment specific emission rate shall be source
tested a minimum of once every twelve months in order to establish an equipment specific emission rate, pursuant to Appendix A, Chapter 4, Subdivision D. These source tests shall be conducted every four calendar quarters after the
initial source test. If a sour ce 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. The source test results shall, upon approval, constitute the basis for assigning equipment specific emission rates which shall be used for purposes of reporting emissions and determining compliance. (ii) Every major SO xsource at a Super Compliant SO xfacility
which is reclassified as a SO xprocess unit with an approved equipment specific concentration limit shall comply with that limit on a sixty-minute basis. In addition, compliance with the approved equipment specific concentration limit shall be demonstrated by source test a minimum of once every six months. Such tests shall be
conducted for a duration of si xty minutes in accordance to test methods listed under Rule 2011, Appendix A,Rule 2011 (Cont.) (Amended January 7, 2005)

2011 - 9 Chapter 4, Subdivision A - Test Methods. 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 f acility shall have the option of reducing the source test frequency to once every four quarters. If any test conduc ted on a four quarter cycle
exceeds the concentration limit th en the facility shall return to conducting source tests every two quarters until the facility is able to demonstrate consecutive compliance over another two year period. (iii) The facility's total annual SO xemissions, as reported in its APEP report, shall not exceed the facility's adjusted compliance year 2003 SO xAllocation. If there are such exceedances for two consecutive years or in any three years, the facility shall no longer be considered Super Compliant. (5) Any Facility Permit holder of a fac ility which is provisionally approved
for SO xSuper Compliant status shall have the option for each major SOx
source to be reclassified as a SOx process unit, 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 SO x Super Compliant status is submitted on or before January 2, 1996, or retroactively from the date of application submittal if the completeRule 2011 (Cont.) (Amended January 7, 2005)

2011 - 10 application is submitted after January 2 and before December 3, 1996. If the facility is unsuccessful at obtaining final approval as a SO xSuper Compliant Facility then the procedur es 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 SOx source reclassified as a process unit for
which SO xemissions had been calculated pursuant to paragraph (d)(2) from the date the facility began monitoring and reporting major SO x source emissions as SO xprocess unit 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 Co mpliant 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
SO xSuper Compliant status and to have all sources at the facility that were reclassified from major SO xsources to SO xprocess units pursuant to paragraph (c)(4) permanently revert back to major SO xsources; (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 SO xsource to a SO xprocess unit 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). (7) If a facility designated as a SO xSuper Compliant Facility pursuant to paragraph (c)(4) exceeds its adjusted compliance year 2003 SO x 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). (8) If the Executive Officer determines that a facility designated as a SO x Super Compliant Facility exceeds its adjusted compliance year 2003 SO x 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 subparagraphRule 2011 (Cont.) (Amended January 7, 2005)

2011 - 11 (c)(4)(D), all sources at the facility that were reclassified from major SO x sources to SO xprocess units pursuant to paragraph (c)(4) shall permanently revert back to major SO xsources and shall become subject to the monitoring and reporting requirements of paragraphs (c)(2) and (c)(3) according to the following schedule: (A) Within 1 month from the end of the compliance year, submit a monitoring, reporting, and recordkeeping plan specifying the use of CEMS; (B) During the shorter of the first twelve months from the end of the compliance year or until the f acility complies with paragraphs (c)(2) and (c)(3), the Facility Permit holder shall comply with the monitoring requirements of paragraph (f)(3) of this rule; and (C) Within one year from the end of the compliance year, comply with paragraphs (c)(2) and (c)(3) and have appropriate direct monitoring equipment installed and certified pursuant to Appendix
