SUPPLEMENTARY INFORMATION: 
P.8 

I. THE RULEMAKING 

The test methods and procedures section of each subpart is being 

revised primarily to clarify the section "by consolidating all procedures 

that pertain to one measurement (e.g., particulate matter concentrations) 

under one paragraph, to delete repetitions of methods already referenced 

within a cited method (e.g., Methods 1, 2, and 3 are referenced by Method 5 

and therefore are not listed again), and to separate alternative methods 

from reference methods. In addition, other changes are being made for 

consistency from one subpart or one.section to another, procedures that 

wece overlooked in the promulgation for requirements already in the 

subparts are being included, and technical errors are being corrected. 

Major amendments besides clarifications are listed below: 

1. Section 60.2: Since the standards are based on reference methods, 

the applicable subpart rather than Appendix A is being used to define the 

reference methods. The title of Appendix A is being revised from 

"Reference Methods" to "Test Methods" in another rulemaking action to allow 

the inclusion of alternative methods in Appendix A. 

2. Section 60.8(b) and (e): Certain phrases or requirements are 

repeated in each subpart. Since they are generally applicable to all 

subparts, these phrases and requirements are being incorporated into the 

General Provisions. 

3. Section 60.45(c)(1): Method 3 for the determination of diluent 

gas (CO2 or O2) is being added. 

4. Section 60.46: The gas temperature of no greater than 433°K 

(320°F) is being revised to "160 _+ 14°C (320 +. 25°F) to be consistent with 

other methods and to allow'for heater fluctuation of +14°C (+25°F). 
P.9 

5. Section 60.44a: Lignite fuel subject to the 340 ng/J standard is 

being added to the equation and a clarifying footnote is being added to 

the table. < 

6. Section 60.47a: Methods 6A and 6B are being added as acceptable 

alternative methods to Methods 6 and 3 for the determination of sulfur 

dioxide in terms of mass per unit of heat input. 

7. Section 60.54: A procedure for Method 3 for a facility without a 

wet scrubber is being added. The grab-sampling technique of Method 3 is 

also being added. 

8. Sections 60.93, 60.123, and 60.133: Sampling rate is being 

changed to sample volume. 

9. Sections 60.165, 60.175, 60.185: The requirement for compressing 

the recorder scale during the performance evaluation test is being deleted. 

10. Sections 60.166, 60.176 and 60.186: The specification for 

monitoring system drift not to exceed 2 percent of span value which is in. 

subpart P and overlooked in subparts Q and R is being added. In addition, 

dry basis measurements of the SO2 concentration is being specified. 

Subparts Db, J, EE, MM, QQ, RR, SS, TT, WW, and FFF are not being 

amended at this time. It has been determined that subparts K, Ka, HHH, 

JJJ, and KKK require^no amendments. 

This rulemaking does not impose emission measurement requirements 

beyond those specified in the current regulations, nor does it change any 

emission standard. Rather, the rulemaking would simply clarify and in 

some instances add a procedure associated with emission measurement or 

process monitoring requirements that would apply irrespective of this 

rulemaking. 
P.10 

II. ADMINISTRATIVE REQUIREMENTS 

A. Public Hearing 

A public hearing will be held, if requested, to discuss the proposed 

rulemaking in accordance with Section 307(d)(5) of the Clean Air Act. 

Persons wishing to^ makeoral presentations should contact EPA at the 

address given in the ADDRESSES section of this preamble. Oral 

presentations will be limited to 15 minutes each. Any member of the public 

may file a written statement with EPA before, during, or within 30 days 

after the hearing. Written statements should be addressed.to the Central 

Docket Section address given in the ADDRESSES section of this preamble. 

A verbatim transcript of the hearing and written statements will be 

available for public inspection and copying during normal working hours at 

EPA's Central Docket Section in Washington, D.C. (see ADDRESSES section of 

this preamble). 

B. Docket 

The docket is an organized and complete file of all the information 

submitted to or otherwise considered by EPA in the development of this 

proposed rulemaking. The principal purposes of the docket are: (1) to 

allow interested parties to identify and locate documents so that they 

can effectively participate in the rulemaking process and (2) to serve 

as the record in case of judicial review (except for interagency review 

materials) [Section 307(d)(7)(A)]. 

C. Office of Management and Budget Reviews 

Executive Order 12291 Review. Under Executive Order 12291, EPA 

must judge whether a regulation is "major" and, therefore, subject to the 

requirement of a regulatory impact analysis. This rulemaking is not major 
P.11 

because it will not have an annual effect on the economy of $100 million 

or more; it will not result in a major increase in costs or prices, and 

there will be no significant adverse effects on competition, employment, 

investment, productivity, innovation, or on the ability of U.S.-based 

enterprises to compete with foreign-based enterprises in domestic or 

export markets. 

This rulemaking was not submitted to the Office of Management and 

Budget (OMB) for review because it amends a regulation already in place 

and does not contain cost implications nor impose additional burdens. 

D. Regulatory Flexibility Act Compliance 

Pursuant to the provisions of 5 U.S.C. 605(b), I hereby certify that 

this attached rule, if promulgated, will not have any economic impact on 

small entities because no changes are being made to testing requirements.

1. The authority citation for Part 60 continues to read as follows: 

Authority: Sections 101, 111, 114, 116, and 301 of the Clean Air 

Act, as amended (42 U.S.C. 7401, 7411, 7414, 7416, and 7601). 

2. Section_60.2 (Subpart A) is amended by revising the definition of 

"Reference method" to read, ""Reference method" means any method of 

sampling and analyzing for an air pollutant as specified in the applicable 

subpart." 

3. In § 60.8(b), the first sentence is amended by removing the word 

"or" before the number "(4)", revising the period at the end of the 

sentence to a comma, and by adding the following phrase, to read as: 

follows: 

(b) .... or (5) approves shorter sampling times and smaller sample 

volumes when necessitated by process variables or other factors. 

4. Section 60.8(e)(1) is amended by adding the following sentence to 

the end of the paragraph to read as follows: 

(e)(1) * * * This includes (i) constructing the air pollution control 

system such that volumetric flow rates and pollutant emission rates can be 

accurately determined by applicable test methods and procedures and (ii) 

providing a stack or duct free of cyclonic flow during performance tests. 

5. Section 60.45(c)(1) is revised to read as follows: 

(c) * * * 

(1) Methods 3, 6, and 7, as applicable, shall be used for the 

performance evaluations of sulfur dioxide and nitrogen oxides continuous 

monitoring systems. Acceptable alternative methods for Methods 3, 6, and 

Method 7 are given in § 60.46(d). 
P.13 

6. In the last line of § 60.45(f)(3), the words "paragraph (d)"

7. Section 60.46 is revised to read as follows: 

§ 60.46 Test methods and procedures. 

(a) In conducting the performance tests required in § 60.8, the owner 

or operator shall use as reference methods and procedures the test methods 

in Appendix A of this part or other methods and procedures as specified in 

this section, except as provided in § 60.8(b). Acceptable alternative 

methods and procedures are given in paragraph (d) of this section. 

(b) The owner or operator shall determine compliance with the 

particulate matter, SO2, and N0X standards in §§ 60.42, 60.43, and 60.44 as 

follows: 

(1) The emission rate (E) of particulate matter, SO2, or N0X shall be 

computed for each run using the following equation: 

E = C F (20.9)/(20.9 - %02) 

where: 

E = emission rate of pollutant, ng/J (lb/million Btu). 

C = concentration of pollutant, ng/dscm (lb/dscf). 

%02 = oxygen concentration, percent dry basis. 

F = factor as determined in § 60.45(f)(4), (5), or (6). 

(2) Method 5 shall be used to determine the particulate matter 

concentration (C) at affected facilities without wet flue-gas-desulfurization 

(FGD) systems and Method 5B shall be used to determine the particulate 

matter concentration (C) after FGD systems. The sampling time and sample 

volume for each run shall be at least 60 minutes and 0.85 dscm (30 dscf). 

The probe and filter holder heating systems in the sampling train may be 

set to provide a gas temperature no greater than 160 _+ 14°C (320 +. 25°F).

P.14 

The emission rate correction factor, integrated or grab sampling and 

analysis procedure of Method 3 shall, be used, to determine the O2 

concentration (/&O2). The O2 sample shall <be obtained simultaneously with, 

and at the same traverse points as, the particulate sample. If the grab 

sampling procedure is used, the O2 concentration for the run shall be the 

arithmetic mean of all the individual O2 sample concentrations at each 

traverse point. 

If the particulate run has more than 12 traverse points, the O2 

traverse points may be reduced to 12 provided that Method 1 is used to 

locate the 12 O2 traverse points. 

(3) Method 9 and the procedures in § 60.11 shall be used to determine 

opacity. 

(4) Method 6 shall be used to determine the SO2 concentration. The 

sampling site shall be the same as that selected for the particulate sample. 

The sampling location in the duct shall be at the centroid of the cross 

section or at a point no closer to the walls than 1 m (3.28 ft). The 

sampling time and sample volume for each sample run shall be at least 

20 minutes and 0.020 dscm (0.71 dscf). Two samples shall be taken during a 

1-hour period, with each sample taken within a 30-minute interval. 

The emission" rate correction factor, integrated sampling and analysis 

procedure of Method 3 shall be used to determine the O2 concentration 

(%02). The O2 sample shall be taken simultaneously with, and at the same 

point as, the SO2 sample. The SO2 emission rate shall be computed for each 

pair of SO2 and O2 samples. The SO2 emission rate (E) for each run shall 

be the arithmetic mean of the results of the two pairs of samples. 
P.15 

(5) Method 7 shall be used to determine the N0X concentration. The 

sampling site and location shall be ,the same.as for the SO2 sample. Each 

run shall consist of four grab samples, wi«th each sample taken at about 

15-minute intervals. 

For each N0X sample, the emission rate correction factor, grab 

sampling and analysis procedure of Method 3 shall be used to determine the 

O2 concentration (%02). The sample shall be taken simultaneously with, and 

at the same point as, the N0X sample. 

The N0X emission rate shall be computed for each pair of N0X and O2 

samples. The N0X emission rate (E) for. each run shall be the arithmetic 

mean of the results of the four pairs of samples. *•-;•• 

(c) When combinations of fossil fuels or fossil fuel and wood residue 

are fired, the owner or.operator [in order to compute the prorated standard 

as shown in §§ 60.43(b) and 60.44(b)] shall determine the percentage (w, x, 

y, or z) of the total heat input derived from each type of fuel as follows: 

(1) The heat input rate of each fuel shall be determined by 

multiplying the gross calorific value of each fuel fired by the rate of 

each fuel burned. 

(2) ASTM Methods D 2015-77 (solid fuels), D 240-76 (liquid fuels), or 

D 1826-77 (gaseous fuels) (incorporated by reference—see § 60.17) shall be 

used to determine the gross calorific values of the fuels. The method used 

to determine the calorific value of wood residue must be approved by the 

Administrator. 

(3) Suitable methods shall be used to determine the rate of each fuel 

burned during each test period, and a material balance over the steam 

generating system shall be used to confirm the rate. 

10 
P.16 

(d) The owner or operator may use the following as alternatives to 

the reference methods and procedures,in this.section or in other sections 

as specified: **• 

(1) For Method 5 or 5B, Method 17 may be used at facilities with or 

without wet FGD systems -if the stack gas temperature at the sampling 

location does not exceed an average temperature of 160°C (320°F). The 

procedures of Sections 2.1 and 2.3 of Method 5B may be used with Method 17 

only if it is used after wet FGD systems. Method 17 shall not be used 

after wet FGD systems if the effluent gas is saturated or laden with water 

droplets.. 

(2) For Method 6, Method 6A (whenever Methods 6 and 3 data are used 

to determine the SO2 emission rate) or Method 6C may be used. 

(3) For Method 7, Method 7A, 7C, 7D, or 7E may be used. If 

Method 7C, 7D, or 7E is used, the sampling time for each run shall be at 

least 1 hour and the integrated sampling approach shall be used to 

determine the O2 concentration (/&O2) for the emission rate correction 

factor. 

(4) For Method 3, Method 3A may be used.

(1) Method 5 or Method 17 shall be used to determine the particulate 

matter concentration. The sampling time and sample volume shall be at 

least 120 minutes and 1.70 dscm (60 dscf). For Method 5, if th'e gas stream 

being sampled is at ambient temperature, the sampling probe and filter may 

be operated without heaters. If the gas stream is above ambient 

temperature, the sampling probe and filter may be operated at a temperature 

high enough, but no higher than 121°C (250°F), to prevent water 

condensation on the filter. 

(2) Method 9 and the procedures in § 60.11 shall be used to determine 

opacity. 

(c) In determining compliance with the particulate matter standards 

in § 60.672(b) and (c), the owner or operator shall use Method 9 and the 

procedures in § 60.11, with the following additions: 

(1) The minimum distance between the observer and the emission source 

shall be 4.57 meters (15 feet). 

(2) The observer shall, when possible, select a position that 

minimizes interference from other fugitive emission sources (e.g., road 

92 
dust). The required observer position relative to the sun (Method 9, 

Section 2.1) must be followed. 

(3) For affected facilities using wet dust suppression for 

particulate matter control, a visible mist is sometimes generated by the 

spray. The water mist must not be confused with particulate matter 

emissions and is not to be considered a visible emission. When a water 

mist of this nature is present, the observation of emissions is to be made 

at a point in the plume where the mist is no longer visible. 

(d) In determining compliance with § 60.672(e), the owner or operator 

shall use Method 22 to determine fugitive emissions. The performance test 

shall be conducted while all affected facilities inside the building are 

operating. " The performance test for each building shall be at least 75 

minutes in duration, with'each side of the building and the roof being 

observed for at least 15 minutes. 

(e) The owner or operator may use the following as alternatives to 

the reference methods and procedures specified in this section: 

(1) For the method and procedure of paragraph (c) of this section, if 

emissions from two or more facilities continuously interfere so that the 

opacity of fugitive emissions from an individual affected facility cannot 

be read, either of the following procedures may be used: 

(i) Use for the combined emission stream the highest fugitive opacity 

standard applicable to any of the individual affected facilities 

contributing to the emissions stream. 

(ii) Separate the emissions so that the opacity of emissions from 

each affected facility can be read. 

93 
(f) To comply with § 60.676(d), the owner or operator shall record 

the measurements as required § 60.676(c) using the monitoring devices in 

§ 60.674(a) and (b) during each particulate matter run and shall determine 

the averages. 

81. In § 60.676(d), the words "those measurements recorded" are 

revised to read "the averaged determined". 

82. Section 60.685 is revised to read as follows: 

§ 60.685 Test methods and procedures. 

(a) In conducting the performance tests required in § 60.8, the owner 

or operator shall use as reference methods and procedures the test methods 

in Appendix A of this part or other methods and procedures as specified in 

this section, except as provided in § 60.8(b). 

(b) The owner or operator shall conduct performance tests while the 

product with the highest loss on ignition (LOI) expected to be produced by 

the affected facility is being manufactured. 

(c) The owner or operator shall determine compliance with the 

particulate matter standard in § 60.682 as follows: 

(1) The emission rate (E) of particulate matter shall be computed for 

each run using the following equation: 

- E = (Ct QSd)/(Pavg

 K ) 

where: 

E = emission rate of particulate matter, kg/Mg (lb/ton). 

C^ = concentration of particulate matter, g/dscm (g/dscf). 

Qsd = volumetric flow rate of effluent gas, dscm/hr (dscf/hr). 

Pavg = average glass pull rate, Mg/hr (ton/hr). 

K = conversion factor, 1000 g/kg (453.6 g/lb). 

94 
p.1 

(2) Method 5E shall be used to determine the particulate matter 

concentration (C^) and the volumetric flow rate (Qsc|) of the effluent gas. 

The sampling time and sample volume shal^ be at least 120 minutes and 2.55 

dscm (90 dscf). 

(3) The average,glass pull rate (Pavg) f°r the manufacturing line 

shall be the arithmetic average of three glass pull rate (P^) 

determinations taken at intervals of at least 30 minutes during each run. 

The individual glass pull rates (P-j) shall be computed using the 

following equation: 

Pi = K' Ls Wm M [1.0 - (LOI/100)] 

where: „._ 

P-j = glass pull rate at interval "i", Mg/hr (ton/hr). 

Ls = line speed, m/min (ft/min). 

Wm = trimmed mat width, m (ft). 

M = mat gram weight, g/nr (lb/ft^). 

LOl = loss on ignition, weight percent. 

K* = conversion factor, 6 x 10~5 (min-Mg)/(hr-g) 

[3 x IO"2 (min-ton)/(hr-lb)3. 

(i) ASTM Standard Test Method D2584-68 (Reapproved 1979) 

(incorporated by reference - see § 60.17), shall be used to determine the 

LOl for each run. 

(ii) Line speed (Ls), trimmed mat width (Wm), and mat gram weight (M) 

shall be determined for each run from the process information or from 

direct measurements. 

(d) To comply with § 60.684(d), the owner or operator shall record 

measurements as required in § 60.684(a) and (b) using the monitoring 

devices in § 60.683(a) and (b) during the particulate matter runs.

FROM: Gerald A. Emison, Direc __ 

Office of Air Quality PTannTn^aTPrJ" Standards (MD-10) 

TO: J . Craig Potter 

Assistant Administrator for Air and Radiation (ANR-443) 

PURPOSE: 

Attached for your consideration is the proposed rulemaking, entitled 

"Amendments to Test Methods and Procedures Sections of Subparts:in 

40 CFR Part 60" which would clarify the test methods and procedures used to 

determine compliance with the applicable standards or related monitoring 

requirements. This rulemaking would be proposed under the authority of 

Sections 101, 111, 114, 116, and 301 of the Clean Air Act, as amended. 

In the present regulations, procedures for conducting a measurement in 

the performance test required, in § 60.8 have been written in segments and 

placed in several paragraphs. Sorting out all the various requirements has 

involved some effort. In addition, some procedures are not clearly 

delineated. This action would clarify the procedures. 

ISSUES: 

This action poses no major issues. 

ENVIRONMENTAL, ECONOMIC, AND ENERGY IMPACTS: 

This action will not result in adverse environmental, economic, 

or energy impacts. 

REPORTING AND RECORDKEEPING REQUIREMENTS: 

There will be no additional reporting and recordkeeping requirements. 

AGENCY RESOURCE REQUIREMENT: 

This action will not require any additional Agency resource 

requirements. 
P.11 

PUBLIC PARTICIPATION: . • < 

Written comments from the public will be received for a 60-day period 

after proposal. A public hearing will be held, if requested. 

ANTICIPATED REACTIONS: 

No opposition is expected to result from this action. 

CHANGES MADE AFTER STEERING COMMITTEE REVIEW: 

This action was not reviewed by Steering Committee since it is not 

considered a major action... 

CHANGES MADE AFTER RED BORDER REVIEW: 

A summary of the comments received during the red border review and 

the actions taken are attached. 

RECOMMENDATION: 

I recommend that you sign the attached action for publication in the 

Federal Register.

P.12 

SUMMARY OF COMMENTS FROM RED BORDER REVIEW AND RESPONSES 

1. Section 60.46(b)(1). The commenter requested that the use of 

the Fc factor and corresponding equation be proposed. 

Response: This suggestion will not be proposed for the following 

reasons: 

a. The Fc factor has a slightly greater variability than the F^ 

factor (6 vs. 3 percent). 

b. The O2 concentration is easily determined by Method 3. 

c. The use of average F<j or Fc factors can cause slight differences 

in the calculated emission rates. When both COg and Og are measured, a 

choice will have to be made on which to use. 

Unless there are clear economic and technical advantages,- we-do not 

feel that a change should be made at this time. 

The use of Methods 6A and 6B as alternative methods for emission 

performance tests and continuous monitoring relative accuracy tests presents 

an inconsistency. Therefore, this rulemaking is being revised to withdraw 

these methods for these purposes. 

2. Section 60.46(b)(5). The commenter'states that the time of 15 

seconds to extract a bag sample for Method 3 analysis is too short. 

Response: This section does not specify the use of a bag sample, but 

the "grab sampling and analysis procedure of Method 3." The grab sampling 

procedure does not use a bag, but a squeeze bulb to pump the sample directly 

into the Orsat. The time of 15 seconds is ample for this procedure. 

3. Section 60.46(d). The commenter suggested that the simultaneous 

determination of particulate matter and sulfur dioxide should be stated as 

an acceptable alternative. 

Response: A paragraph has been added as suggested. 

4. Section 60.46(d). The commenter states that the proposal should 

clearly state that the O2 concentration must be determined by Method 3 if 

Method 6A is used. 

Response: When Method 6A is used, O2 concentration is not necessary. 

However, for the reasons given under comment 1, reference to Method 6A is 

being deleted. 

5 & 6. Sections 60.54(c)(1)(ii) and 60.74(b)(3). The commenter 

believes that Method 4 should be mentioned as some testing firms, or owners, 

or operators will overlook this need. 
P.13 

Response: One of the objectives of the proposed revisions is to delete 

repetition of methods already referenced in a. cited method. In this case, 

Method 2 cites Method 4. We do not feel that the "possibility" of someone 

overlooking this is sufficient to warrant further clarification. 

7. Sections 60.204, 60.214, 60.224, 60.234, and 60.244. The commenter 

feels that the equations in these sections should incorporate the summation 

signs to reflect that an affected facility may have more than one emission 

point. ~ 

Response: The equations and nomenclature have been revised accordingly. 

8. Section 60.276. The commenter notes that "§ 60.27b" should be 

changed to "§ 60.276." 

Response: Apparently the copy received by the commenter made the "5" 

look like a "b." The correct reference is "§ 60.275." 

9. Section 60.285(d)(1). The commenter suggests that the number of 

sample injects that constitutes a test run should be specified. 

Response: Since the procedure is unique to this method, the number of 

injects that are required for a test run is specified in Method 16. The 

sampling time of at least 3 hours, but no longer than 6 hours has been 

added. 

10. Section 60.285(f)(2). The commenter recommended that the section 

be reworded to clarify the sampling time and sample volume for Methods 16A 

and 16B. 

Response: In Methods 16A and 16B, the sampling rate is critical and 

is specified within the test method. Therefore, in this case, only the 

sampling time is necessary. The volume need not be specified. 

11. Section 60.374(b)(2). The commenter requests that similar changes 

as under comment 7 be made. In addition, "control devices" should be changed 

to "emission sources." 

Response: The section has been revised accordingly. 

12. Section 60.474(c)(2). The commenter states that English units 

should be added. 

Response: This suggestion has been incorporated.. 

13. Section 60.485(b)(1). The commenter suggested some changes inMethod 21. 

Response: Method 21 is being revised under a separate action. 
P.14 

I. THE RULEMAKING 

The test methods and procedures section of each subpart is being 

revised primarily to clarify the section by- consolidating all procedures 

that pertain to one measurement (e.g., particulate matter concentrations) 

under one paragraph, to delete repetitions of methods already referenced 

within a cited method (e.g., Methods 1, 2, and 3 are referenced by Method 5 

and therefore are not listed again), and to separate alternative methods 

from reference methods. In addition, other changes are being made for 

consistency from one subpart or one section to another, procedures that 

were overlooked in the promulgation for requirements already in .the 

subparts are being included, and technical errors are being corrected. 

Major amendments besides clarifications are listed below: 

1. Section 60.2: Since the standards are based on reference methods, 

the applicable subpart rather than Appendix A is being used to define the 

reference methods. The title of Appendix A is being revised from 

"Reference Methods" to "Test Methods" in another rulemaking action to allow 

the inclusion of alternative methods in Appendix A. 

2. Section 60.8(b) and (e): Certain phrases or requirements are 

repeated in each subpart. Since they are generally applicable to all 

subparts, these phrases and requirements are being incorporated into the 

General Provisions. 

3. Sections 60.45(c)(1) and 60.47a(i)(1): Methods 6A and 6B are 

being withdrawn to be consistent with newly revised § 60.46(b)(1). These 

methods should not be used for emission performance tests and continuous 

monitor relative accuracy tests. 
P.15 

4. Section 60.44a: Lignite fuel subject to the 340 ng/J standard is 

being added to the equation and a clarifying footnote is being added to 

the table. 

5. Section 60.54: A procedure for Method 3 for a facility without a 

wet scrubber is being added. The grab-sampling technique of Method 3 is 

also being added. 

6. Sections 60.93, 60.123, and 60.133: Sampling rate is being 

changed to sample volume. 

7. Sections 60.165, 60.175, 60.185: The requirement for compressing 

the recorder scale during the performance evaluation test is being deleted. 

8. Sections 60.166, 60.176 and 60.186: The specification for 

monitoring system drift not to exceed 2 percent of span value which is in 

subpart P and overlooked in subparts Q and R are being added. In addition, 

dry basis measurements of the SO2 concentration is being specified. 

Subparts Db, J, EE, MM, QQ, RR, SS, TT, WW, and FFF are not being 

amended at this time. It has been determined that subparts K, Ka, HHH, 

JJJ, and KKK require no amendments. 

This rulemaking does not impose emission measurement requirements 

beyond those specified in the current regulations, nor does it change any 

emission standard. Rather, the rulemaking would simply clarify and in 

some instances add a procedure associated with emission measurement or 

process monitoring requirements that would apply irrespective of this 

rulemaking.

(b) During a performance test required by § 60.8, the owner or 

operator shall determine the minimum required reduction efficiencies (Z) of 

SO2 emissions as required in § 60.642(a) and (b) as follows: 

(1) The average sulfur feed rate (X) shall be computed as follows: 

X = K Qa Y 

where: 

X = average sulfur feed rate, long ton/day. 

Qa = average volumetric flow rate of acid gas from sweetening unit, 

dscf/day. 

Y = average H2S concentration in acid gas feed from sweetening 

unit , percent by volume. 

K = (32 lb S/lb-mole)/[(100%)(385.36 dscf/lb-mole)(2240 lb/long ton)] 

= 3.707 x 10~7
