determine the number of whole allowances, the number of allowances shall be rounded down for decimals less than 

0.50 and rounded up for decimals of 0.50 or greater. 

D. An allowance is not a property right, and is a limited authorization to emit one ton of sulfur 

dioxide valid only for the purpose of meeting the requirements of 20.2.81 NMAC. No provision of this WEB trading 

program or other law should be construed to limit the authority of the United States or the department to terminate 

or limit such authorization.

E. Early reduction bonus allocation. Any WEB source that reduces permitted annual sulfur 

dioxide emissions to a level that is below the floor level allocation established for that source in section C1 of the 

sulfur dioxide milestones and backstop trading program implementation plan between 2003 and the program trigger 

year may apply to the department for an early reduction bonus allocation. The application shall be submitted no later 

than ninety days after the program trigger date. Any WEB source that applies and receives early reduction bonus 

allocations shall retain the records referenced below for a minimum of five years after the early reduction bonus 

allowance is certified in accordance with section C1.1(a) (3) of the implementation plan. The application for an early 

reduction bonus allocation shall contain the following information. 

 (1) Copies of all permits or other enforceable documents that include annual sulfur dioxide emissions 

limits for the WEB source during the period the WEB source was generating the early reductions. Such permits or 

enforceable documents shall require monitoring for sulfur dioxide emissions that meets the requirements in 

Subsection A and Subsection C of 20.2.81.106 NMAC and that the monitoring provisions were in effect one year 

prior to the beginning of the credit generating period. 

 (2) Copies of emissions monitoring reports, for one year prior to the beginning of the credit

generating period and for the period the WEB source was generating the early reductions, that documents the actual

annual sulfur dioxide emissions. The emissions monitoring reports during the credit generating period must

demonstrate that the actual annual sulfur dioxide emissions were below the floor level allocation established for that

source in section C1 of the sulfur dioxide milestones and backstop trading program implementation plan. 

 (3) Demonstration that the floor level established for the source in accordance with section C1 of the 

sulfur dioxide milestones and backstop trading program implementation plan was calculated using data that are 

consistent with the new monitoring methodology under Subsection A of 20.2.81.106 NMAC. If new monitoring 

techniques change the floor level for the source, then a demonstration of the new floor level based on new 

monitoring techniques shall be included in the application. 

F. Request for allowances for new WEB sources or modified WEB sources.

 (1) A new WEB source or an existing WEB source that has increased production capacity through a 

permitted change in operations under 20.2.72 NMAC, 20.2.74 NMAC or 20.2.79 NMAC may apply to the

 (a) A new WEB source is eligible to apply for an annual allocation equal to the permitted 

20.2.81 NMAC 7
annual sulfur dioxide emission limit for that source after the source has commenced operation. 

 (b) An existing WEB source is eligible to apply for an annual allocation equal to the permitted 

annual sulfur dioxide emission limit for that source that is attributable to any amount of production capacity that is

greater than the permitted production capacity for that source as of January 1, 2003. 

 (c) A source that has received a retired source exemption under Subsection D of 20.2.81.101 

NMAC is not eligible to apply for an allocation from the new source set-aside. 

 (2) The application for an allocation from the new source set-aside shall contain the following 

information: 

 (a) for existing WEB sources, documentation that shows the permitted production capacity of 

the source before and after the new permit; or

 (b) for new WEB sources, documentation of the actual date of the commencement of operation

 (d) whenever an audit of any monitoring certified under 20.2.81 NMAC, and a review of the 

initial certification or recertification application, reveal that any system or component should not have been certified 

or recertified because it did not meet a particular performance specification or other requirement of 20.2.81 NMAC, 

both at the time of the initial certification or recertification application submission and at the time of the audit, the 

department will issue a notice of disapproval of the certification status of such system or component; for the 

purposes of this paragraph, an audit shall be either a field audit of the facility or an audit of any information

submitted to the department regarding the facility; by issuing the notice of disapproval, the certification status is 

revoked prospectively, and the data measured and recorded shall not be considered valid quality-assured data from

the date of issuance of the notification of the revoked certification status until the date and time that the WEB source 

completes subsequently approved initial certification or recertification tests in accordance with the procedures in 

Subsection J of 20.2.81.106 NMAC; the WEB source shall apply the substitute data procedures in Paragraph 2 of 

Subsection L of 20.2.81.106 NMAC to replace, prospectively, all of the invalid, non-quality-assured data for each 

disapproved system or component.

[20.2.81.106 NMAC - N, 12/31/03]

20.2.81.107 ALLOWANCE TRANSFERS:

A. Procedure. To transfer allowances, the account representative shall submit the following 

information to the tracking system administrator: 

 (1) the transfer account number(s) identifying the transferor account; 

 (2) the transfer account number(s) identifying the transferee account; 

 (3) the serial number of each allowance to be transferred; and 

 (4) the transferor's account representative's name and signature and date of submission. 

B. Deadline. The allowance transfer deadline is midnight Pacific standard time March 1 of each year 

(or if this date is not a business day, midnight of the first business day thereafter) following the end of the control 

period. By this time, the transfer of the allowances into the WEB source's compliance account must be correctly

submitted to the tracking system administrator in order to demonstrate compliance under Subsection A of 

20.2.81.109 NMAC for that control period. 

C. Retirement of Allowances. To transfer allowances for the purpose of retirement, the account

representative shall submit the following information to the tracking system administrator: 

 (1) the transfer account number(s) identifying the transferor account; 

 (2) the serial number of each allowance to be retired; and 

 (3) the transferor's account representative's name and signature and date of submission accompanied 

by a signed statement acknowledging that each retired allowance as no longer available for future transfers from or 

to any account. 

[20.2.81.107 NMAC - N, 12/31/03]

20.2.81.108 USE OF ALLOWANCES FROM A PREVIOUS YEAR:

A. Any allowance that is held in a compliance account or general account shall remain in such an 

account unless and until the allowance is deducted in conjunction with the compliance process, or transferred to 

another account. 

B. In order to demonstrate compliance under Subsection A of 20.2.81.109 NMAC for a control

period, WEB sources shall only use allowances allocated for that current control period or any previous year. 

Because all allowances held in a special reserve compliance account for a WEB source that monitors certain units in 

accordance with Subsection B of 20.2.81.106 NMAC will be deducted for compliance for each control period, no 

banking of such allowances for use in a subsequent year is permitted by 20.2.81 NMAC. 

C. If flow control procedures for the current control period have been triggered as outlined in section

C4.2 of the sulfur dioxide milestones and backstop trading program implementation plan, then the use of allowances 

that were allocated for any previous year shall be limited as follows. 

 (1) The number of allowances that are held in each compliance account and general account as of the 

allowance transfer deadline for the immediately previous year and that were allocated for any previous year shall be 

determined. 

 (2) The number determined in Paragraph 1 shall be multiplied by the flow control ratio established in

accordance with section C4.2 of the sulfur dioxide milestones and backstop trading program implementation plan to 

determine the number of allowances that were allocated for a previous year that can be used without restriction for 

the current control period. 

 (3) Allowances that were allocated for a previous year in excess of the number determined in (2) may 

also be used for the current control period. If such allowances are used to make a deduction, two allowances shall be 

deducted for each deduction of one allowance required under 20.2.81.109 NMAC. 

 D. Special provisions for the year 2018. After compliance with the 2017 allowance limitation has 

been determined in accordance with Subsection A of 20.2.81.109 NMAC, allowances allocated for any year prior to 

2018 shall not be used for determining compliance with the 2018 allowance limitation or any future allowance 

20.2.81 NMAC 17
limitation.

[20.2.81.108 NMAC - N, 12/31/03]

20.2.81.109 COMPLIANCE:

A. Compliance with Allowance Limitations. 

 (1) The WEB source shall hold allowances, in accordance with Paragraph 2 of Subsection A of 

20.2.81.109 NMAC and 20.2.81.108 NMAC, as of the allowance transfer deadline in the WEB source's compliance 

account (together with any current control year allowances held for the WEB source by the department under 

Subsection B of 20.2.81.106 NMAC in an amount not less than the total sulfur dioxide emissions for the control

period from the WEB source, as determined under the monitoring and reporting requirements of 20.2.81.106 

NMAC. 

 (a) For each source that is a WEB source on or before the program trigger date, the first control 

period is the calendar year that is six years following the calendar year for which sulfur dioxide emissions exceeded 

the milestone in accordance with procedures in section A of the sulfur dioxidemilestones and backstop trading 

program implementation plan. 

 (b) For any existing source that becomes a WEB source after the program trigger date, the first

control period is the calendar year that is four years following the inventory year in which the source exceeded the 

sulfur dioxide emissions threshold. 

 (c) For any new WEB source after the program trigger date the first control period is the first

full calendar year that the source is in operation. 

 (d) If the WEB trading program is triggered in accordance with the 2013 review procedures in 

section A4 of the sulfur dioxide milestones and backstop trading program implementation plan, the first control

period for each source that is a WEB source on or before the program trigger date is the year 2018. 

 (2) Allowance transfer deadline. An allowance may only be deducted from the WEB source's 

compliance account if:

 (a) the allowance was allocated for the current control period or meets the requirements in

20.2.81.108 NMAC for use of allowances from a previous control period; and 

 (b) the allowance was held in the WEB source's compliance account as of the allowance 

transfer deadline for the current control period, or was transferred into the compliance account by an allowance 

transfer correctly submitted for recording by the allowance transfer deadline for the current control period.

 (3) Compliance with allowance limitations shall be determined as follows. 

 (a) The total annual sulfur dioxide emissions for all sulfur dioxide emitting units at the source 

that are monitored under Subsection B of 20.2.81.106 NMAC, as reported by the source in Paragraph 2 or 4 of 

Subsection O of 20.2.81.106 NMAC, and recorded in the emissions tracking database shall be compared to the 

allowances held in the source's special reserve compliance account as of the allowance transfer deadline for the 

current control period, adjusted in accordance with 20.2.81.108 NMAC. If the emissions are equal to or less than 

the allowances in such account, all such allowances shall be retired to satisfy the obligation to hold allowances for 

such emissions. If the total emissions from such units exceeds the allowances in such special reserve account, the 

WEB source shall account for such excess emissions in the following Subparagraph b. 

 (b) The total annual sulfur dioxide emissions for all sulfur dioxide emitting units at the source 

that are monitored under Subsection A of 20.2.81.106 NMAC, as reported by the source in Paragraph 2 or 4 of 

Subsection O of 20.2.81.106 NMAC, and recorded in the emissions tracking database, together with any excess 

emissions as calculated in the preceding Subparagraph a, shall be compared to the allowances held in the source's 

compliance account as of the allowance transfer deadline for the current control period, adjusted in accordance with 

20.2.81.108 NMAC. 

 (4) Other than allowances in a special reserve compliance account for units monitored under

Subsection B of 20.2.81.106 NMAC, to the extent consistent with 20.2.81.108 NMAC, allowances shall be deducted 

for a WEB source for compliance with the allowance limitation as directed by the WEB source's account

representative. Deduction of any other allowances as necessary for compliance with the allowance limitation shall 

be on a first-in, first-out accounting basis in the order of the date and time of their recording in the WEB source's 

compliance account, beginning with the allowances allocated to the WEB source and continuing with the allowances 

transferred to the WEB source's compliance account from another compliance account or general account. The 

allowances held in a special reserve compliance account pursuant to Subsection B of 20.2.81.106 NMAC shall be 

deducted as specified in Subparagraph a of Paragraph 3 of Subsection A of 20.2.81.109 NMAC. 

B. Certification of compliance.

 (1) For each control period in which a WEB source is subject to the allowance limitation, the account 

20.2.81 NMAC 18
representative of the source shall submit to the department a compliance certification report for the source. 

 (2) The compliance certification report shall be submitted no later than the allowance transfer 

deadline of each control period, and shall contain the following: 

 (a) identification of each WEB source; 

 (b) at the account representative's option, the serial numbers of the allowances that are to be 

deducted from a source's compliance account for compliance with the allowance limitation; and 

 (c) the compliance certification report according to Paragraph 3 of this section. 

 (3) In the compliance certification report, the account representative shall certify, based on reasonable 

inquiry of those persons with primary responsibility for operating the WEB source in compliance with the WEB 

trading program, whether the WEB source for which the compliance certification is submitted was operated during

the control period covered by the report in compliance with the requirements of the WEB trading program

applicable to the source including: 

 (a) whether the WEB source operated in compliance with the sulfur dioxide allowance 

limitation;

 (b) whether sulfur dioxide emissions data has been submitted to the department in accordance 

with Subsection A of 20.2.81.106 NMAC and other applicable guidance, for review, revision as necessary, and 

finalization for forwarding to the sulfur dioxide allowance tracking system for recording; 

 (c) whether the monitoring plan that governs the WEB source has been maintained to reflect

the actual operation and monitoring of the source, and contains all information necessary to attribute sulfur dioxide 

emissions to the source, in accordance with Subsection a of 20.2.81.106 NMAC; 

 (d) whether all the sulfur dioxide emissions from the WEB source if applicable, were 

monitored or accounted for either through the applicable monitoring or through application of the appropriate

missing data procedures; 

 (e) if applicable, whether any sulfur dioxide emitting unit for which the WEB source is not

required to monitor in accordance with Paragraph 3 of Subsection A of 20.2.81.106 NMAC remained permanently 

retired and had no emissions for the entire applicable period; and 

 (f) whether there were any changes in the method of operating or monitoring the WEB source 

that required monitor recertification; if there were any such changes, the report shall specify the nature, reason, and 

date of the change, the method to determine compliance status subsequent to the change, and specifically, the 

method to determine sulfur dioxide emissions. 

C. Penalties for any WEB source exceeding its allowance limitations.

 (1) Allowance deduction penalties. 

 (a) If emissions from a WEB source exceed the allowance limitation for a control period, as 

determined in accordance with Subsection A of 20.2.81.109 NMAC , the source's allowance held in its compliance 

account will be reduced by an amount equal to two times the source's tons of excess emissions. If the compliance 

account does not have sufficient allowances allocated for that control period, the required number of allowances 

shall be deducted from the WEB source's compliance account regardless of the control period for which they were 

allocated, once allowances are recorded in the account. 

 (b) Any allowance deduction required under this section shall not affect the liability of the 

owners and operators of the WEB source for any fine, penalty or assessment or their obligation to comply with any 

other remedy, for the same violation, as ordered under the Clean Air Act, implementing regulations or applicable

state or tribal law. Accordingly, a violation can be assessed each day of the control period for each ton of sulfur 

dioxide emissions in excess of its allowance limitation if the department so chooses. 

 (2) Financial penalties. A financial penalty of $5,000 per ton of sulfur dioxide emissions in excess of 

the WEB source's allowance limitation shall be levied. Each ton represents a separate violation.

D. Liability.

 (1) WEB source liability for non-compliance. Separate and regardless of any automatic penalties 

assessed for allowance deduction penalty and financial penalty, a WEB source that violates any requirement of 

20.2.81 NMAC is subject to civil and criminal penalties under the Air Quality Control Act and the Clean Air Act. 

Each day of the control period is a separate violation, and each ton of sulfur dioxide emissions in excess of a source's 

allowance limitation is a separate violation.

 (2) General liability. 

 (a) Any provision of the WEB trading program that applies to a source or an account

representative shall apply also to the owners and operators of such source. 

 (b) Any person who violates any requirement or prohibition of the WEB trading program shall

be subject to enforcement pursuant to applicable state, tribal or federal law. 

20.2.81 NMAC 19
 (c) Any person who knowingly makes a false material statement in any record, submission, or 

report under this WEB trading program shall be subject to criminal enforcement pursuant to the applicable state, 

tribal or federal law.

error tests. 

 (iv) Calibration drift shall be 5.0 percent of the span. 

 (v) Methods 15A, 16, or approved alternatives for total sulfur, are the reference methods 

for the relative accuracy test. The relative accuracy test shall include a bias test in accordance with Paragraph 3 of 

Subsection D of 20.2.81.111 NMAC. 

 (c) All continuous fuel flow meters shall comply with the provisions of Section 2.1.5 of 

Appendix D to 40 CFR Part 75. 

 (d) The hourly mass sulfur dioxide emissions rate for all the fuel combustion devices 

monitored by this approach shall be calculated using the following equation:

Et = (CS)(Qf)(K) 

where: Et = Total sulfur dioxide emissions in lb/hr from applicable fuel gas combustion devices 

CS = Sulfur content of the fuel gas as H2S(ppmv) 

Qf = Fuel gas flow rate to the applicable fuel gas combustion devices (scf/hr) 

K = 1.660 x 10-7 (lb/scf)/ppmv 

 (2) In place of a CFGMS in Paragraph 1 of Subsection B of 20.2.81.111 NMAC, fuel gas combustion 

devices having a common source of fuel gas may be monitored with an sulfur dioxide CEMS flow CEMS and (if 

necessary) a moisture monitoring system at only one location, if the CEMS monitoring at that location is 

representative of the sulfur dioxide emission rate (lb sulfur dioxide/scf fuel gas burned) of all applicable fuel gas 

combustion devices. Continuous fuel flow meters shall be used in accordance with Paragraph 2 of Subsection B of 

20.2.81.111 NMAC, and the fuel gas combustion device monitored by a CEMS shall have separate fuel metering. 

 (a) Each CEMS for sulfur dioxide and flow, and (if applicable) moisture, shall comply with the 

operating requirements, performance specifications, and quality assurance requirements of 40 CFR Part 75. 

 (b) All continuous fuel flow meters shall comply with the provisions of Section 2.1.5 of 

Appendix D to 40 CFR Part 75. 

 (c) The sulfur dioxide hourly mass emissions rate for all the fuel gas combustion devices 

monitored by this approach shall be determined by the ratio of the amount of fuel gas burned by the CEMSmonitored fuel gas combustion device to the total fuel gas burned by all applicable fuel gas combustion devices 

using the following equation:

Et = (Em)(Qt)/(Qm) 

where: Et = Total sulfur dioxide emissions in lb/hr from applicable fuel gas combustion devices. 

Em = sulfur dioxide emissions in lb/hr from the CEMS-monitored fuel gas combustion device, calculated using 

Equation F-1 or (if applicable) F-2 in Appendix F to 40 CFR Part 75 

Qt = Fuel gas flow rate (scf/hr) from applicable fuel gas combustion devices. 

Qm = Fuel gas flow rate (scf/hr) to the CEMS-monitored fuel gas combustion device.

 (3) In place of a CFGMS in Paragraph 1 of Subsection B of 20.2.81.111 NMAC, fuel gas combustion 

devices having a common source of fuel gas may be monitored with an sulfur dioxide - diluent CEMS at only one 

location, if the CEMS monitoring at that location is representative of the sulfur dioxide emission rate (lb sulfur

dioxide/mmBtu) of all applicable fuel gas combustion devices. If this option is selected, the owner or operator shall 

conduct fuel gas sampling and analysis for gross calorific value (GCV), and shall use continuous fuel flow metering 

in accordance with Paragraph 1 of Subsection B of 20.2.81.111 NMAC, with separate fuel metering for the CEMSmonitored fuel gas combustion device. 

 (a) Each sulfur dioxide - diluent CEMS shall comply with the applicable provisions for sulfur

dioxide monitors and diluent monitors in 40 CFR Part 75, and shall use the procedures in Section 3 of Appendix F to

Part 75 for determining sulfur dioxide emission rate (lb/mmBtu) by substituting the term sulfur dioxide for nox in

that section, and using a K factor of 1.660 x 10 - 7 (lb/scf) ppmv instead of the NOx K factor. 

 (b) All continuous fuel flow meters and fuel gas sampling and analysis for GCV to determine 

the heat input ratio shall comply with the applicable provisions of Section 2.1.5 and 2.3.4 of Appendix D to 40

 (c) The sulfur dioxide hourly mass emissions rate for all the fuel gas combustion devices 

monitored by this approach shall be determined by the ratio of the fuel gas heat input to the CEMS-monitored fuel

gas combustion device to the total fuel gas heat input to all applicable fuel gas combustion devices using the 

following equation:

Et = (Em)(Qt)/(GCV) / 106

where: Et = Total sulfur dioxide emissions in lbs/hr from applicable fuel gas combustion devices. 

Em = sulfur dioxide emissions in lb/mmBtu from the CEMS - monitored fuel gas combustion device. 

Qt = Fuel gas flow rate (scf/hr) to the applicable fuel gas combustion devices. 

GCV = Fuel Gross Calorific Value (Btu/scf) 

106 = Conversion from Btu to million Btu

20.2.81.112 NMAC PREDICTIVE FLOW MONITORING SYSTEMS FOR KILNS WITH POSITIVE

PRESSURE FABRIC FILTER:

A. Applicability. The provisions of this protocol are applicable to cement kilns or lime kilns that: 

 (1) are controlled by a positive pressure fabric filter; 

 (2) combust only a single fuel, no fuel blends; and 

 (3) have operating conditions upstream of the fabric filter that the WEB source documents would

reasonably prevent reliable flow monitor measurements; this protocol does not modify the sulfur dioxidemonitoring 

requirements in 20.2.81.106 NMAC. 

B. Monitoring requirements. 

 (1) A cement or lime kiln with a positive pressure fabric filter shall use a predictive flow monitoring

system (PFMS) to determine the hourly kiln exhaust gas flow. 

 (2) A PFMS is the total equipment necessary for the determination of exhaust gas flow using process 

or control device operating parameter measurements and a conversion equation, a graph, or computer program to

produce results in cubic feet per hour. 

 (3) The PFMS shall meet the following performance specifications. 

 (a) Sensors readings and conversion of sensor data to flow in cubic feet per hour must be 

automated.

 (b) The PFMS must allow for the automatic or manual determination of failed monitors. At a 

minimum a daily determination must be performed. 

 (c) The PFMS shall have provisions to check the calibration error of each parameter that is 

individually measured. The owner or operator shall propose appropriate performance specifications in the initial 

monitoring plan for all parameters used in the PFMS comparable to the degree of accuracy required for other 

20.2.81 NMAC 23
monitoring systems used to comply with 20.2.81 NMAC. The parameters shall be tested at two levels, low: 0 to 20 

percent of full scale, and high: 50 to 100 percent of full scale. The reference value need not be certified. 

 (d) The relative accuracy of the PFMS must be < 10.0 percent of the reference method average 

value, and include a bias test in accordance with Paragraph 3 of Subsection D of 20.2.81.112 NMAC. 

C. Certification Requirements. The PFMS is subject to initial certification testing. The source 

owner or operator shall: 

 (1) demonstrate the ability of the PFMS to identify automatically or manually a failed monitor; 

 (2) provide evidence of calibration testing of all monitoring equipment. Any tests conducted within

the previous 12 months of operation that are consistent with the QA/QC plan for the PFMS are acceptable for initial 

certification purposes; and 

 (3) perform an relative accuracy test audit and accompanying bias test once every four operating 

quarters. Calculate the relative accuracy (and bias adjustment factor) as described in Appendix A to 40 CFR Part 75. 

An out of control period occurs whenever the flow relative accuracy is greater than 10.0 percent of the mean value 

of the reference method. 

D. Quality assurance and quality control requirements. A quality assurance and quality control 

plan shall be developed and implemented for each PFMS in compliance with Sections 1 and 1.1 of Appendix B of 

40 CFR Part 75, and the following:

 (1) perform a daily monitor failure check; 

 (2) perform calibration tests of all monitors for each parameter included in the PFMS. At a minimum,

calibrations shall be conducted prior to each relative accuracy test audit; and 

 (3) perform a relative accuracy test audit and accompanying bias test once every four operating 

quarters. Calculate the relative accuracy (and bias adjustment factor) as described in Appendix A to 40 CFR Part 

75. An out of control period occurs whenever the flow relative accuracy is greater than 10.0 percent of the mean 

value of the reference method. 

E. Missing data. For any period in which valid data are not being recorded by the PFMS specified 

in this section, hourly missing or invalid data shall be replaced with substitute data in accordance with the flow 

monitor missing data requirements for non-load based units in subpart D of 40 CFR Part 75. 

F. Monitoring plan requirements. In addition to the general monitoring plan requirements of 

20.2.81.106 NMAC, the owner or operator shall meet the following additional requirements. 

 (1) The monitoring plan shall document the reasons why stack flow measurements upstream of the 

fabric filter are unlikely to provide reliable flow measurements over time. 

 (2) The initial monitoring plan shall explain the relationship of the proposed parameters and stack 

flow, and discuss other parameters considered and the reasons for not using those parameters in the PFMS. The 

department may require that the subsequent monitoring plan include additional explanation and documentation for 

the reasonableness of the proposed PFMS.
