procedures and testing methods contained in the Arizona Testing Manual; 40 CFR 52, Appendices D and E; 40 CFR 60, 

Appendices A through F; and 40 CFR 61, Appendices B and C 

shall be used to determine compliance with the requirements 

established in this Chapter or contained in'permits issued pursuant to this Chapter. 

B. Except as otherwise provided in this subsection the opacity of 

visible emissions shall be determined by Reference Method 9 

of the Arizona Testing Manual. A permit may specify a 

method, other than Method 9, for determining the opacity of 

emissions from a particular emissions unit, if the method has 

been promulgated by the Administrator in 40 CFR 60, Appendix A. 

C. Except as otherwise specified in this Chapter, the heat content 

of solid fuel shall be determined according to ASTM method 

D-3176-89, (Practice for Ultimate Analysis of Coal and Coke) 

and ASTIvI method D-2015-91, (Test Method for Gross Calorific Value of Coal and Coke by the Adiabatic Bomb Calorimeter). 

D. Except for ambient air monitoring and emissions testing 

required under Articles 9 and 11 of this Chapter, alternative 

and equivalent test methods in any test plan submitted to the 

Director may be approved by the Director for the duration of 

that plan provided that the following three criteria are met: 

1. The alternative or equivalent test method measures the 

same chemical and physical characteristics as the test 

method it is intended to replace. 

2. The alternative or equivalent test method has substantially the same or better reliability, accuracy, and precision as the test method it is intended to replace. 

3. Applicable quality assurance procedures are followed in 

accordance with the Arizona Testing Manual, 40 CFR 60 

or other quality assurance methods which are consistent 

with principles contained in the Arizona Testing Manual 

or 40 CFR 60 as approved by the Director.

R18-2-312. Performance Tests 

A. Within 60 days after a source subject to the permit requirements of this Article has achieved the capability to operate at 

its maximum production rate on a sustained basis but no later 

than 180 days after initial start-up of such source and at such 

other times as may be required by the Director, the owner or 

operator of such source shall conduct performance tests and 

furnish the Director a written report of the results of the tests. 

B. Perfonnance tests shall be conducted and data reduced in 

accordance with the test method and procedures contained in 

the Arizona Testing Manual unless the Director: 

1. Specifres or approves, in specific cases, the use of a reference method with minor changes in methodology; 

2. Approves the use of an equivalent method; 

3. Approves the use of an alternative method the results of 

which he has detennined to be adequate for indicating 

whether a specific source is in compliance; or 

4. Waives the requirement for performance tests because the 

owner or operator of a source has demonstrated by other 

means to the Director's satisfaction that the source is in 

compliance with the standard. 

5. Nothing in this Section shall be construed to abrogate the 

Director's authority to require testing. 

C. Performance tests shall be conducted under such conditions as 

the Dire.ctor shall specify to the plant operator based on representative performance of the source. The owner or operator 

shall make.available to the Director such records as may be 

necessary to determine the conditions of the performance tests. 

Operations during periods of start-up, shutdown, and malfunction shall not constitute representative conditions of performance tests unless otherwise specified in the applicable 

standard. 

D. The owner or operator of a permitted source shall provide the 

Director two weeks prior notice of the perfonmance test to 

afford the Director the opportunity to have an observer present. 

E. The owner or operator of a pennitted source shall provide, or 

cause to be provided, performance testing facilities as follows: 

1. Sampling ports adequate for test methods applicable to 

such facility. 

2. Safe sampling platform(s). 

3. Safe access to sampling platform(s).

4. Utilities for sampling and testing equipment. 

F. Each performance test shall consist of three separate runs 

using the applicable test method. Each run shall be conducted 

for the time and under the conditions specified in the applicable standard. For the purpose of determining compliance with 

an applicable standard, the arithmetic means of results of the 

three runs shall apply. In the event that a sample is accidentally 

lost or conditions occur in which one of the three runs is 

required to be discontinued because of forced shutdown, failure of an irreplaceable portion of the sample train, extreme 

meteorological conditions, or other circumstances beyond the 

owner or operator's control, compliance may, upon the Director's approval, be determined using the arithmetic means of 

the results of the two other runs. If the Director, or the Director's designee is present, tests may only be stopped with the 

Director's or such designee's approval. If the Director, or the 

Director's designee is not present, tests may only be stopped 

for good cause, which includes forced shutdown, failure of an 

irreplaceable portion of the sample train, extreme meteorological conditions, or other circumstances beyond the operator's 

control. Termination of testing without good cause after the 

first run is commenced shall constitute a failure of the test. 

G. Except as provided in subsection (H) compliance with the 

emission limits established in this Chapter or as prescribed in 

permits issued pursuant to this Chapter shall be determined by 

the performance tests specifred in this Section or in the permit. 

H. In addition to perfonnance tests specifred in this Section, compliance with specific emissiori limits may be determined by: 

l. Opacity tests. 

2. Emission limit compliance tests specifrcally designated 

as such in the regulation establishing the emission limit to 

be complied with. 

3. Continuous emission monitoring, where applicable quality assurance procedures are followed and where it is designated in the permit or in an applicable requirement to 

show compliance. 

I. Nothing in this Section shall be so construed as to prevent the 

utilization of ineasurements from emissions monitoring 

devices or techniques not designated as performance tests as 

evidence of compliance with applicable good maintenance and 

operating requirements.

R18-2-728. Standards of Performance for Existing Ammonium Sul6de Manufacturing Plants 

A. The provisions of this Section are applicable to the following 

affected facilities in ammonium sulfide manufacturing plants: 

sulfide unloading facilities, reactor-absorbers, bubble cap 

scrubbers, and fiune incinerators. 

B. No person shall cause, allow or permit to be emitted into the 

atmosphere, from any type of incinera'tor or other outlet 

smoke, fumes, gases, particulate matter or other gas-borne 

material, the opacity of which exceeds 20%. 

C. No person shall cause, allow or permit to be emitted into the 

atmosphere from any emission point from any incinerator, or 

to pass a convenient measuring point near such emission point, 

particulate matter of coincentrations in excess of 0.1 grain per 

cubic foot, based on dry flue gas at standard conditions, corrected to 12% carbon dioxide. 

D. No person shall allow hydrogen sulfide to be emitted froni any 

location in such manner and amount that the concentration of 

such emissions into the ambient air at any occupied place 

beyond the premises on which the source is located exceeds 

0.03 parts per million by volume for any averaging period of 

30 minutes or more. 

E. Where a stack, vent or other outlet is at such a level that fumes, 

gas mist, odor, smoke, vapor or any combination thereof constituting air pollution are discharged to adjoining property, the 

Director may require the installation of abatement equipment 

or the alteration of such stack, vent; 'or other outlet by the 

owner or operator thereof to a degree that will adequately 

dilute, reduce or eliminate the discharge of air pollution to 

adjoining property. 

F. The owner or operator of any ammonium sulfide tailgas incinerator subject to the provisions of this Section shall do both of 

the following: 

1. Install, calibrate, maintain, and operate a fow measuring 

device which can be used to determine either the mass or 

volume of tailgas charged to the incinerator. The flow 

measuring device shall have an accuracyof ± 5% over its 

operating range. 

2. Provide access to the tailgas charged so that a well-mixed 

representative grab sample can be obtained. 

G The test methods and procedures required by this Section are 

as follows: 

1. The reference methods in 40 CFR 60, Appendix A shall 

be used to determine compliance with the standards prescribed in this Section as follows: 

a. Method 5 for the concentration of particulate matter 

and the associated moisture content; 

b. Method 1 for sample and velocity traverse; 

C. Method 2 for velocity and volumetric fow rate; 

d. Method 3 for gas analysis and calculation of excess 

air, using the integrated sample .technique; 

e. Method 11 shall be used to determine the concentration of H2S and Method 6 shall be used to determine 

the concentration of S0 2.

2. For Method 5, the sampling tiine for each run shall be at 

least 60 minutes and the minimum sample volume shall 

be 0.85 dscm (30.0 dscf) except that shorter sampling 

times and smaller sample volumes, when necessitated by 

process variables or other factors, may be approved by 

the Director. 

3. Particulate matter emissions, expressed in g/dscm, shall 

be corrected to 12% CO 2by using the following formula: 

C12 = 12c 

%CO2 

where: 

CtZ= the concentration of particulate matter corrected to 12% COZ, 

c = the concentration of particulate matter as 

measured by Method 5, and 

%COz= the percentage of CO2 as measured by 

1Vlethod 3, or, whetr applicable, the adjusted outlet 

CO2percentage. 

4. If Method 11 is used, the gases sampled shall be introduced into the sampling train at approximately atmospheric pressure. Where firel gas lines are operating at 

pressures substantially above atmosphere, this may be 

accomplished with a flow control valve. If the line pressure is high enough to operate the sampling train without 

a vacuum pump, the pump may be eliminated from the 

sampling train. The sample shall be drawn from a point 

near the centroid of the fuel gas line. The minimum sampling time shall be 10 minutes and the minimum sampling volume 0.01 dscm (0.35 dscf) for each sample. The 

arithmetic average of two samples of equal sampling time 

shall constitute one run. Samples shall be taken at 

approximately one-hour intervals. For most fuel gases, 

sample times exceeding 20 minutes may result in depletion of the collecting solution, although fuel gases containing low concentrations of hydrogen sulfide. may , 

necessitate sampling for longerperiods of time. 

5. If Method 5 is used, Method 1 shall be used for velocity 

traverses and Method 2 for determining velocity and volumetric flow rate. The sampling site for determining CO2 

concentration by Method 3 shall be the same as for determining volumetric flow rate by Method 2. The sampling 

point in the duct for determining SO Zconcentration by 

Method 3 shall be at the centroid of the cross section if 

the cross sectional area is less than 5 m Z(54 ft) or at a 

point no closer to the walls than 1 m(3.28 feet) if the 

cross sectional area is 5 mZor more and the centroid is 

more than 1 meter from the wall. The sample shall be 

extracted at a rate proportional to the gas velocity at the 

sampling point. The minimum sampling time shall be 10 

minutes and the minimum sampling volume 0.01 dscm 

(0.36 dscf) for each sample. The arithmetic average of 

two samples of equal sampling time shall cvnstitute one 

run. Samples shall be taken at approximately one-hour 

intervals.

for 02and COZ, respectively. The gases may be analyzed at 

less frequent intervals if longer shelf lives are guaranteed by 

the manufacturer. 

A9.4.2. For nonextractive continuous monitoring systems measuring gases, minimum procedures shall include upscale 

check(s) using a certified calibration gas cell or test cell which 

is fianctionally equivalent to a known gas concentration. The 

zero check may be performed by computing the zero value 

from upscale measurements or by mechanically producing a 

zero condition. 

A9.4.3. For continuous monitoring systems measuring opacity of 

emissions, minimum procedures shall include a method for 

producing a simulated zero opacity condition and an upscale 

(span) opacity condition using a certified neutral density filter 

or other related technique to produce a known obscuration of 

the light beam. Such procedures shall provide a system check 

of the analyzer intemal optical surfaces and all electronic circuitry including the lamp and photodetector assembly. .

A9.5. Except for system breakdowns, repairs, calibration 

checks, and zero and span adjustments required under A9.4. 

above, all continuous monitoring systems shall be in continuous operation and shall meet minimum frequency of operation 

requirements as follows: 

A9.5.1. All continuous monitoring systems referenced by A9.3.1. 

and A9.3.2. above for measuring opacity of emissions shall 

complete a minimum of one cycle of operation (sampling, analyzing, and data recording) for each successive 10-second 

period. 

A9.5.2. All continuous monitoring systems referenced by A9.3.1. 

above for measuring oxides of nitrogen, sulfur dioxide, carbon 

dioxide, or oxygen shall complete a minimum of one cycle of 

operation (sampling, analyzing, and data recording) for each 

successive 15-minute period. 

A9.5.3. All continuous monitoring systems referenced by A9.3.2. 

above, except opacity, shall complete a minimum of one cycle 

of operation (sampling, analyzing, and data recording) for 

each successive one-hour period. 

A9.6. All continuous monitoring, systems for monitoring 

devices shail be installed such that representative measurements of emissions or process parameters from the affected 

facility are obtained. Additional procedures for location of 

continuous monitoring systems contained in the applicable 

Performance Specifications of 40 CFR 60, Appendix B shall 

be used. 

When the effluents from a single affected facility or two 

or more affected facilities subject to the same emission standards are combined before being released to the atmosphere, 

the owner or operator may install applicable continuous monitoring systems on each effluent or on the combined effluent. 

When the affected facilities are not subject to the same emission standards, separate continuous monitoring systems shall 

be installed on each effluent. When the effluent from one 

affected facility is released to the atmosphere through more 

than one point, the owner or operator shall install applicable 

continuous monitoring systems on each separate eftluent 

unless the installation of fewer systems is approved by the 

Director. 

Owners or operators of all continuous monitoring systems for measurement of opacity shall reduce all data to sixminute averages and for systems other than opacity to onehour averages, respectively. Six minute opacity averages shall 

be calculated from 24 or more data points equally spaced over 

each six-minute period. For systems other than opacity, onehour averages shall be computed from four or more data points 

equally spaced over each one-hour period. Data recorded 

during periods of system breakdowns, repairs, calibration 

checks, and zero and span adjustments shall not be included in 

the data averages computed under this subsection. An arithmetic or integrated average of all data may be used. The data output of all continuous monitoring systems may be recorded in 

reduced or nonreduced form (e.g. ppm pollutant and percent 

02 or lb/million Btu of pollutant). All excess emissions shall 

be converted into units of the standard using the applicable 

conversion procedures specified in subparts. After conversion 

into units of the standard, the data may be rounded to the same 

number of significant digits used in these rules to specify the 

applicable standard (e.g., rounded to the nearest 1% opacity). 

Upon written application by an owner or operator, the 

Director may approve alternatives to any monitoring procedures or requirements of these rules including, but not limited 

to the following: 

.1. Alternative monitoring requirements when installation of 

a continuous monitoring system or monitoring device specified by these rules would not provide accurate measurements 

due to liquid water or other interferences caused by substances 

with the eilluent gases. 

A9.9.2. Alterriative monitoring requirements when the affected 

facility is infrequently operated. 

A9.9.3. Alternative monitoring requirements to accommodate 

continuous monitoring systems that require additional measurements to correct for stack moisture conditions. 

A9.9.4. Alternative loeations for installiing continuous monitoring 

systems or irionitoring devices when the owner or operator can 

demonstrate that installation at alternate locations will enable 

accurate and representative measurements. 

A9.9.5. Alternative methods of converting pollutant concentration measurements to units of the standards. 

A9.9.6. Alternative procedures for perfonning daily checks of 

zero and span drift that do not involve use of span gases or test 

cells. 

A9.9.7. Alternatives to the ASTM test methods or sampling procedures specified by any subpart. 

A9.9.8. Alternative continuous monitoring systems that do not 

meet the design or performance requirements in Performance 

Specification 1 in 40 CFR 60, Appendix B but adequately 

demonstrate a definite and consistent relationship between its 

measurements and the measurements of opacity by a system 

complying with the requirements in Performance Specification 

1. The Director may require that such demonstration be performed for each affected facility. 

A9.9.9. Alternative monitoring requirements when the effluent 

from a single affected facility or the combined eflluent from 

two or more affected facilities are released to the atmosphere 

through more than one point.
