an additional 96 hours.Rule 2012 (Cont.) (Amended January 7, 2005)

2012 - 4 (3) The Facility Permit holder of a major NO x source shall: (A) install, maintain and operate a reporting device to electronically report total daily mass emissions of NO x and daily status codes to
the District Central NO x Station for each major NO x 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 NO x and daily status codes, the Fac ility Permit holder shall be granted 24 hours to submit the required report. Between July 1, 1995 and December 31, 1995, NO x emissions after the 24-hour extension, shall be calculated using interim reporting procedures set forth in Appendix A, Chapter 2. Starti ng January 1, 1996 and thereafter,
NO xemissions after the 24-hour extension shall be calculated pursuant to the missing data requi rements set forth in Appendix A, Chapter 2. For each major NO x source opting to comply with subparagraph (c)(9), reports of NO x mass emissions shall be electronically filed on a monthly instead of daily basis; and (B) submit Monthly Emissions Reports aggregating NO x emissions from all major sources within 15 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. (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 tota l daily mass emissions of NO 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. NO x emissions reported after the 96-hour extension shall be calculated pursuant to the missing data requirements set forth in Appendi x A, Chapter 2. The provisionsof this subparagraph shall be limited to no more than three nonconsecutive occurrences per compliance year. (D) The requirement of calculating emissions using Missing Data Procedures under subparagraph (c)(3)(A) shall not apply if theRule 2012 (Cont.) (Amended January 7, 2005)

2012 - 5 failure to report the total daily mass emissions of NO x and daily
status codes is due to a demonstrated 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 that the raw data as obtained by the direct monitoring device is stored at the facility. NO x emissions reported after the 48-hour extension shall be calculated pursuant to the missing data requi rements 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. (i) The Facility Permit holder of major NO x sources may reclassify its major NO x sources to large NO x sources provided that (1) the facility's annual NO x emissions as properly reported in its 1994 compliance year APEP report are already at or below the level of its adjusted compliance year 2003 NO x Allocation. The adjusted compliance year 2003 NO x Allocation shall be the compliance year 2003 NO x Allocation as calculated pursuant to Rule 2002 subdivision (e) plus any compliance year 2003 NO x 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 NO x 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 NO x 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 convertedRule 2012 (Cont.) (Amended January 7, 2005)

2012 - 6 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 NO x 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 NO x 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 NO x 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 NO x sources may submit a complete application
for NO x Super Compliant status. Such application must also include a complete application for permit
modifications to install NO x emission reduction equipment or to make any other physical modifications to substantially reduce emissions from each major NO x 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 NO x emissions to a level not to exceed its adjusted compliance year 2003 NO x 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 A2 of Rule 1303;Rule 2012 (Cont.) (Amended January 7, 2005)

2012 - 7 (ii) Upon issuance of the pe rmit 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 NO x Super Compliant status for purposes of paragraph (c)(5). (iii) Final approval of NO x 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 NO x emissions as reported in its APEP report are at a level at or below the facility's adjusted compliance year
2003 NO x Allocation on a permanent basis no later than the facility's 1998 compliance year; (III) The Facility Permit holder has retired all NO x 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 NO x 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 (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 NO x source tests conducted for each major NO x source to be reclassified as a largeRule 2012 (Cont.) (Amended January 7, 2005)

2012 - 8 NO xsource. The initial source tests shall be conducted pursuant to Appendix A, Chapter 5, Subdi visions 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 fac ilities. Additionally, the Facility Permit holder shall select an equipment-specific concentration limit for each major source which will be reclassified as a large
NO x source. For each major source which will be reclassified as a large NO x source that operates at two or more separate and significantly distinct operating loads, the Facility Permit holder may select no more than two equipment specific concentration limits, and assign one for each di fferent operating load. 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 NO x source at a Super Compliant NO x facility which is reclassified as a large NO x 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, Ch apter 5, Subdivisions A, B, and D and shall constitute the basis for assigning
concentration limits. 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 ofa source test indicate noncompliance with the concentr ation 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.Rule 2012 (Cont.) (Amended January 7, 2005)

2012 - 9 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 conduc ted 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 NO x emissions, as reported in its APEP report, shall not exceed the facility's adjusted compliance year 2003 NO x Allocation. If there are such exceedances for two consecutive years or any three years, the facility shall no longer be considered Super Compliant. NOx emissions from portable equipment used in the manufacturing of as phalt rubber binder, which is owned and operated by a person other than the Facility Permit holder and used at a Super Compliant facility for not more than 1,500 hours in any one compliance year, need not be included in the APEP report. (5) The Facility Permit holder of a facility which is provisionally approved
for NO xSuper 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
NO xSuper Compliant status is s ubmitted 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 NO x 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 NO x emissions had been calculated pursuant to paragraph (d)(2) from the date the facility began monitoring and reporting major NO x source emissions as large NO x source emissions to
the date a CEMS is installed and certified.Rule 2012 (Cont.) (Amended January 7, 2005)

2012 - 10 (6) After final approval of Super Compliant status, a Facility Permit holder may elect to discontinue its Supe r 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
NO xSuper Compliant status and to have all sources at the facility that were reclassified from major NO x sources to large NO x sources pursuant to paragraph (c)(4) permanently revert back to major NO 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 NO x source to a large NO x 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). (7) If a facility designated as a NO x Super Compliant Facility pursuant to paragraph (c)(4) exceeds its adjusted compliance year 2003 NO x Allocation, then the facility sha ll acquire, pursuant to Rule 2007,
sufficient RTCs to cover such ex ceedance and shall be considered in violation of Rule 2004(d)(1). (8) If the Executive Officer determines that a facility designated as a NO x Super Compliant Facility exceeds its adjusted compliance year 2003
NO xAllocation for two consecutive year s 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
NO xsources to large NO x sources pursuant to paragraph (c)(4) shall permanently revert back to major NO x sources and shall become subject to the monitoring and reporting requi rements 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 recordk eeping plan specifying the use of CEMS;Rule 2012 (Cont.)
