Rule 2012 (Cont.) (Amended January 7, 2005)

2012 - 4

(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

24 hours to submit the required report. Between July 1, 1995 and

December 31, 1995, NOx emissions after the 24-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 24-hour extension shall be calculated

pursuant to the missing data requirements set forth in Appendix

A, Chapter 2. For each major NOx source opting to comply with

subparagraph (c)(9), reports of NOx mass emissions shall be

electronically filed on a monthly instead of daily basis; and

(B) submit Monthly Emissions Reports aggregating NOx 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 total daily mass emissions of NOx

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. NOx emissions reported after the 96-hour

extension shall be calculated pursuant to the missing data

requirements set forth in Appendix A, Chapter 2. The provisions

of 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 the
Rule 2012 (Cont.) (Amended January 7, 2005)

2012 - 5

failure to report the total daily mass emissions of NOx 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. NOx

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.

(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
Rule 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 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 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 A2 of Rule 1303;
Rule 2012 (Cont.) (Amended January 7, 2005)

2012 - 7

(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).

(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

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

(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
Rule 2012 (Cont.) (Amended January 7, 2005)

2012 - 8

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. For each major source which will be reclassified as

a large NOx 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 different 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 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, 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 of a source test indicate noncompliance 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.
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 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. NOx emissions from portable equipment used

in the manufacturing of asphalt 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 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.
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 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).

(7) 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).

(8) 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;
Rule 2012 (Cont.) (Amended January 7, 2005)

(c)(2) and (c)(3), the Facility Permit holder shall comply with the

monitoring requirements of paragraph (h)(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 A.

(9) Non-Operated Major NOx Source

Subparagraphs (c)(2)(A) and (c)(2)(B) shall not apply to a major NOx

source if the Facility Permit holder complies with the following

requirements.

(A) The Facility Permit holder submits an application for each major

NOx source to classify such source to be a non-operated major

NOx source, demonstrating to the satisfaction of the Executive

Officer that such source will not be operated in the current or next

compliance year, and receives written approval from the

Executive Officer. The Executive Officer shall further not

approve an application to classify a major source to be a nonoperated major NOx source if such source had previously been

classified as a non-operated source for any time during the 18

calendar months prior to the filing date of the application.

(B) The Facility Permit holder accepts and complies with all permit

conditions imposed to ensure compliance with subparagraph

(c)(9)(C) and (c)(9)(D).

(C) The Facility Permit holder shall comply with the requirements

under either subclause (i) or (ii):

of operation except as provided under paragraph (c)(10).

Until the source meets the requirements of subparagraph

(c)(2)(A) or (c)(2)(B), emissions shall be determined

pursuant to the Missing Data Procedures as specified

under Rule 2012, Appendix A, Chapter 2, Subdivision E.

(10) A non-operated major NOx source qualifies for a one-time only CEMS

certification period if:

(A) the source has never been monitored by a RECLAIM certified

CEMS since October 15, 1993, and

(B) the source has been in compliance with paragraph (c)(9) during

the 12 months prior to the date the source was operated.

This one-time only CEMS certification period shall commence on the

first day of any operation in any compliance year and ends on the date

the CEMS is certified or 12 calendar months from the first day of

operation, whichever date is earlier. By the end of this CEMS

certification period, the Facility Permit holder shall install, operate, and

maintain all required monitoring, reporting, and recordkeeping systems.

During this CEMS certification period, the Facility Permit holder shall
Rule 2012 (Cont.) (Amended January 7, 2005)

2012 - 13

comply with the monitoring, reporting, and recordkeeping requirements

of paragraphs (h)(2) and (h)(3).

(11) If an approved non-operated major NOx source fails to meets the

requirements of the paragraph (c)(9) that source shall no longer be

considered a non-operated major NOx source, and the facility permit

holder of the source shall be considered in violation for each day from

the start of the compliance year and emissions shall be determined as if

the source had been operating from the start of the compliance year

according to Missing Data Procedures as specified under Rule 2012,

Appendix A, Chapter 2, clause (E)(1)(d)(iii), except for those days in

which the Facility Permit holder can conclusively prove that the source

any continuous 60 minutes as specified in the Facility Permit for

that source.

(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).
Rule 2012 (Cont.) (Amended January 7, 2005)

2012 - 17

(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 5.

(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 to amend the emission factor to a concentration limit,

equipment-specific emission rate, 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 equipmentspecific 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 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

or process unit complies with that limit in ppm over any continuous 60

minutes. The alternative concentration limit or equipment-specific

emission rate for a large source, and the concentration limit, equipmentspecific emission rate, 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 a concentration limit or an equipment-specific emission

rate for a large source, or a concentration limit, equipment-specific

emission rate, or category-specific emission rate for a process unit, if the

concentration limit, equipment-specific emission rate, or categoryspecific emission rate 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
Rule 2012 (Cont.) (Amended January 7, 2005)

2012 - 18

Facility Permit. The alternative concentration limit or equipmentspecific emission rate for a large source, or concentration limit,

equipment-specific emission rate or category-specific emission rate for a

process unit shall take effect prospectively from the date the Facility

Permit is amended.

(g) General Requirements

District within 60 days of the date the source test was conducted. In lieu

of submitting the first source test report, the Facility Permit holder may

submit the results of a source test not more than three years old which

meets applicable requirements of this rule when conducted. If a large

source has not been operated within the same quarter of the date a source

test is required, the source test may be conducted by the end of seven

consecutive days or 15 cumulative days of resumed operation. The

Facility Permit holder shall keep daily records to demonstrate that the

large source had not been operated for the three month period and upon

resumption of operation the Facility Permit holder shall keep records of

each day operated until the required test. The source testing requirement

does not apply to large sources which comply with paragraphs (c)(2) and
Rule 2012 (Cont.) (Amended January 7, 2005)

(c)(3), or paragraphs (c)(2), (d)(2)(B), and Appendix A, Chapter 3,

Subdivision K.

(3) An equipment-specific emission rate or category-specific emission rate

for process units shall comply with source testing guidelines to be

established by the Executive Officer or designee by March 31, 1994.

(4) Every process unit that is approved by the Executive Officer to use a

concentration limit for emission reporting shall be source tested every

five-year period, with the first five-year period ending on December 31,

2004 for Cycle 1 facilities and June 30, 2005 for Cycle 2 facilities. The

compliance date for the first source test shall be within 12 months of the

approval of the concentration limit by the Executive Officer but, no later

than the last day of the five-year period in which the use of a

concentration limit is approved by the Executive Officer. Any source

test conducted to satisfy this requirement must be conducted at least 12

months following the tests submitted to satisfy the previous five-year

period. Such source test results shall be submitted to the District within

60 days of the date the source test was conducted. If a process unit has

not been operated within the prior quarter of the date a source test is

required, the source test may be conducted by the end of either seven

consecutive days or 15 cumulative days of resumed operation. The

Facility Permit holder shall keep daily records to demonstrate that the

process unit had not been operated for the three month period and upon

resumption of operation the Facility Permit holder shall keep records of

each day operated until the required test. Test firings of emergency

standby equipment, which are less than 60 minutes in duration, are not

considered operation for the purposes of these source test requirements

so long as such test firings are done to verify availability of the unit for

their intended use and once such test firings are completed the units are

shutdown. Records of the date and duration when the unit is test fired

shall be maintained for a period of three years, and shall be made

accessible to the Executive Officer upon request.

(k) Exemption

The provisions of this rule shall not apply to gas flares.
