SUPPLEMENTARY INFORMATION: 

I. THE RULEMAKING 

The test methods and procedures section of each subpart has been 

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, have not been listed again), and to separate alternative 

methods from reference methods. In addition, other changes have been 

made for consistency from one subpart or one section to another, procedures 

that were overlooked in the promulgation for requirements already in the 

subparts have been included, and technical errors have been 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. 
P.5 

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

repeated in each subpart or in a number of subparts. Since they are 

generally applicable to all subparts, these phrases and requirements have 

been incorporated into the General Provisions. 

3. 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. 

4. Sections 60.46 and 60.48a: The use of Fc factors has been 

incorporated into the procedures. This change was the result of comments 

received during proposal. 

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 is being added. In addition, 

dry basis measurements of the SO2 concentration are being specified. 

Subparts Db, J, EE, MM, QQ, RR, SS, TT, l.'W, and FFF ere 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 
P.6 

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. 

II. PUBLIC PARTICIPATION 

The amendments were proposed in the FEDERAL REGISTER on February 19, 

1988 (53 FR 5082). To provide interested persons the opportunity for 

oral presentation of data, views, or arguments concerning the proposed 

amendments, a public hearing was scheduled for April 4, 1988, at the Research 

Triangle Park, North'Carolina, but was not held because no one wished to 

make an oral presentation. The public comment period was from February 19, 

1988, to May 4, 1988. Three comment letters were received. 

III. SIGNIFICANT COMMENTS AND CHANGES TO THE PROPOSED AMENDMENTS 

The three comment letters on the proposed amendments were from 

industry and a utility ad hoc group, and all comments concerned only 

§ 60.8, Subpart D (Fossil-Fuel Fired Steam Generators), and Subpart Da 

(Electric Utility Steam Generating Units). There were no comments on the 

amendments made to the other 39 subparts. 

All three commenters objected to the withdrawal of Methods 6A and 6B 

primarily because no clear justification was given. The primary reason for 

the proposed withdrawal of Methods 6A and 6B for emission performance tests 

and continuous monitoring relative accuracy tests is due to the slightly 

greater variability of the Fc factor than the F<j factor (6 percent vs. 

3 percent). Both Methods 6A and 6B are based on the Fc factor. 

The first commenter suggested that if the difference between the Fc 

and Fd factors was of concern, ultimate analysis of coal samples could be 

4 '. 
P.7 

used to prove the appropriateness of the Fc factor. After considering the 

commenter's suggestion, EPA has decided to allow the use of Methods 6A and 

6B as alternative methods with one restriction. If the average Fc factor 

in Method 19 is used and when the emission rate is from 0.97 to 1.00 of the 

emission standard or the relative accuracy is from 17 and 20 percent, then 

a check of the acceptability of the Fc factor is made. 

This same commenter suggested that Method 8 and Method 7D be designated 

as alternatives to Method 6. In Section 2.1 of Method 6, Method 8 is 

designated as an acceptable alternative to Method 6 provided that a heated 

filter is placed between the probe and isopropanol impinger. Since this 

applies to wherever Method 6 is used, it is unnecessary to repeat its 

acceptability as an alternative in Section 60.46(d)(3). Method 7D cannot 

be added without going through the rulemaking process. The Agency plans to 

consider this action in the near future. 

The second commenter stated that the proposed amendment to Section 

60.8(e)(1) could be made clearer by referencing appropriate sections of 

Method 1. The Agency feels that paragraph (e)(l)(i), which states 

"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," is sufficiently clear to give the 

necessary intent. In the case of particulate matter, Methods 1, 2, and 5 

are the applicable procedures, which contain criteria and procedures for 

ensuring that measurements of flow and emission rates are accurate. The 

Agency agrees that paragraph (e)(l)(ii) could be made clearer. It has been 

revised as follows: "providing a stack or duct free of cyclonic flow during 

performance tests, as demonstrated by applicable test methods and procedures." 
P.8 

This same commenter suggested that Section 60.45(f) can be shortened 

by referencing Section 3 of Method 19. The Agency agrees and plans to 

revise this paragraph under a separate action. 

This commenter also asked whether the expressions "The owner or operator 

may use" and "at the sole discretion of the owner and operator" have the 

same impact to EPA. Both expressions mean the same thing. Only the source 

owner or operator may choose to use the alternative methods for determining 

compliance. However, it does not mean that only the owner or operator may 

use the alternative methods. Alternative methods are those that have been 

shown to produce results adequate for determining compliance and may have 

no bias, a positive bias, or a siightly,negative bias. The intent of such 

expression was to indicate that control agencies should not mandate the use 

of alternative methods if the owner or operator chooses not to use them. 

However, the alternative status does not preclude the control agency from 

using the method for compliance purposes; it only means that an agency must 

consider positive biases, if any (some alternative methods have been shown 

not to exhibit any bias), when using alternative methods. 

The second commenter suggested that reference to § 60.46 in 

§§ 60.a(c)(4) and (d)(1) be deleted. The reference was made to § 60.46 to 

indicate that only F^ factors should be used. However, with the changes 

allowing the use of the Fc factors, the reference has been deleted. 

This same commenter stated that the first equation in Section 

60.43a(h)(2) has no meaning and therefore is unnecessary. The EPA realizes 

that the first equation would not be applicable. The equation was included 

to satisfy the requirements of Section 111(a) of the Clean Air Act, as 

amended. 
P.9 

Two of tne commenters pointed out several typesetting errors. These 

have been noted. 

As a result of an EPA internal review, the proposed addition of a 

minimum sampling time of 120 minutes to §§ 60.386(b)(3) and 60.675(b)(3) 

has been rescinded because an averaging time was not considered essential 

for determining compliance in these subparts. 

IV. ADMINISTRATIVE 

A. 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 

rulemaking. The docket is a dynamic file, since material is added 

throughout the rulemaking development. The docketing system is intended 

to allow members of the- public and industries involved to identify 

readily and locate documents so they can effectively participate in the 

rulemaking process. Along with the statement of basis and purpose of the 

proposed and promulgated rule, and EPA responses to significant comments, 

the contents of the docket, except for interagency review materials, will 

serve as the record in case of judicial review [Clean Air Act, Section 

307(d)(7)(A)]. 

B. Office of Management and Budget Reviews 

Under Executive Order 12291, EPA is required to judge whether a 

regulation is a "major rule" and, therefore, subject to the requirements ofa regulatory impact analysis. The Agency has determined that this 

regulation would result in none of the adverse economic effects set forth 

in Section 1 of the Order as grounds for finding a regulation to be a 

"major rule." The rulemaking does not impose emission measurement 

7 
P.10 

requirements beyond those specified in the current regulations, but 

instead, provides simplification and clarification in the test methods 

and procedures sections of the regulation that would apply irrespective of 

this rulemaking. The Agency has, therefore, concluded that this regulation 

is not a "major rule" under Executive Order 12291. 

C. Regulatory Flexibility Act Compliance 

The Regulatory Flexibility Act (RFA) of 1980 requires the identification 

of potentially adverse impacts of Federal regulations upon small business 

entities. The Act specifically requires the completion of an RFA in those 

instances where small business impacts are possible. Because this rulemaking 

imposes no adverse economic impacts, an RFA has not been conducted. 

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

this promulgated rule will not have any economic impact on small entities 

because no changes are being made to testing requirements.

of Fd and Fc in Method 19, i.e., Fo a = 0.209 (Fda / Fc a ),

 the n th e following 

procedure shall be followed: 

(A) When F0 is less than 0.97 Fo a , then E shall be increased by that 

proportion under 0.97 Fo a , e.g., if F0 is 0.95 Fo a , E shall be increased by 

2 percent. This recalculated value shall be used to determine compliance 

with the emission standard. 

(B) When F0 is less than 0.97 Fo a and when the average difference (d~) 

between the continuous monitor minus the reference methods is negative, 

then E shall be increased by that proportion under 0.97 Fo a , e.g., if F0 is 

0.95 Fo a , E shall be increased by 2 percent. This recalculated value shall 

be used to determine compl i ance -with .the relative accuracy specification. 

(C) When F0 is greater than 1.03 Fo a and when the average difference 

cf is positive, then E shall be decreased by that proportion over 1.03 Fo a , 

e.g., if F0 is 1.0b Fo a , E shall be decreased by 2 percent. This 

recalculated value shall be used to determine compliance with the relative 

accuracy specification. 

(2) 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. 

(3) Particulate matter and SO2 may be determined simultaneously with 

the Method 5 train provided that the following changes are made: 

14 
P.17 

(i) The filter and impinger apparatus in Sections 2.1.5 and 2.1.6 of 

Method 8 is used in place of the condenser (Section 2.1.7) of Method 5. 

(ii) All applicable procedures in Method 8 for the determination of 

SO2 (including moisture) are used. 

(4) For Method 6, Method 6C may be used. Method 6A may also be used 

whenever Methods 6 and 3 data are specified to determine the SO2 emission 

rate, under the conditions in paragraph (d)(1) of this section. 

(5) 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 ho.ur and the integrated sampling approach shall be used to 

determine the 0 2 concentration (%02) for the emission rate-correction 

factor. 

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

Administrator finds that the facility was in compliance with the mass 

standard during the performance test but failed to meet the zero opacity 

standard, the Administrator will establish and promulgate in the FEDERAL 

REGISTER an opacity standard for the blowing still that will be the opacity 

standard when fuel oil is used to fire the afterburner. When the 

afterburner is fired with natural gas, the zero percent opacity remains the 

applicable opacity standard.

(2) The continuous readings from the process flowmeter shall be used 

to determine the average volumetric flow rate (Qa) in dscf/day of the acid 

gas from the sweetening unit for each run. 

(3) The Tutwiler procedure in § 60.648 or a chromatographic procedure 

following ASTM E-260 (incorporated by reference—see § 60.17) shall be used 

to determine the H2S concentration in the acid gas feed from the sweetening 

unit . At least one sample per hour (at equally spaced intervals ) shal l be 

taken during each 4-hour run. The arithmetic mean of al l samples shall be 

the average H2S concentration (Y) on a dry basis for the run. By 

multiplying the result from the Tutwiler procedure by 1.62 x 10~3, the 

units gr/100 scf are converted to volume percent. 

(4) Using the information from paragraphs (b)(1) and (3), Tables 1 

and 2 shall be used to determine the required initia l (Zi) and continuous 

(Zc) reduction efficiencies of SO2 emissions. 

(c) The owner or operator shall determine compliance with the SO2 

standards in § 60.642(a) or (b) as follows: 

(1) The emission reduction efficiency (R) achieved by the sulfur 

recovery technology shall be computed for each run using the following 

equation: 

R = (100 S)/(S + E) 

(2) The level indicators or manual soundings shall be used to measure 

the liquid sulfur accumulation rate in the product storage tanks. Readings 

taken at the beginning and end of each run, the tank geometry, sulfur 

density at the storage temperature, and sample duration shall be used to 

determine the sulfur production rate (S) in kg/hr for each run. 

89 
(3) The emission rate (E) of sulfur shall be computed for each run as 

follows: 

E = Ce QSd/K 

where: 

Ce = concentration of sulfur equivalent (SO2 + TRS), g/dscm. 

QSd

 = volumetric flow rate of effluent gas, dscm/hr. 

K = conversion factor, 1000 g/kg. 

(4) The concentration (Ce) of sulfur equivalent shall be the sum of 

the SO2 and TRS concentrations, after being converted to sulfur equivalents. 

For each run and each of the test methods specified in this paragraph (c) 

of this section, the sampling time shall be at least 4 hours. Method 1 

shall be used to select the sampling site. The sampling point in the duct 

shall be at the centroid of the cross-section if the area is less than 5 m2 

(54 ft2) or at a point no closer to the walls than 1 m (39 in.) if the 

cross-sectional area is 5 m2 or more, and the centroid is more than 1 m 

(39 in.) from the wall. 

(i) Method 6 shall be used to determine the SO2 concentration. Eight 

samples of 20 minutes each shall be taken at 30-minute intervals. The 

arithmetic average in mg/dscm shall be the concentration for the run. The 

concentration in mg/dscm shall be multiplied by 0.5 to convert the results 

to sulfur equivalent. 

(ii) Method 15 shall be used to determine the TRS concentration from 

reduction-type devices or where the oxygen content of the effluent gas is 

less than 1.0 percent by volume. The sampling rate shall be at least 3 

liters/min (0.1 ft3/min) to insure minimum residence time in the sample 

line. Sixteen samples shall be taken at 15-minute intervals. The 

90 
P.94 

arithmetic average of all the samples shall be the concentration for the 

run. The concentration in ppm TRS as H2S shall be multiplied by 

1.352 x IO"6 to convert the results to sulfur equivalent. 

(iii) Method 16A shall be used to determine the TRS concentration 

from oxidation-type devices or where the oxygen content of the effluent gas 

is greater than 1.0 percent by volume. Eight samples of 20 minutes each 

shall be taken at 30-minute intervals. The arithmetic average shall be the 

concentration for the run. The concentration in ppm TRS as H2S shall be 

multiplied by 1.352 x IO"6 to convert the results to sulfur equivalent. 

(iv) Method 2 shall be used to determine the volumetric flow rate of 

the effluent gas. A velocity traverse shall be conducted at the beginning 

and end of each run. The arithmetic average of the two measurements shall 

be used to calculate the volumetric flow rate (Qsd) f°r the run. For the 

determination of the effluent gas molecular weight, a single integrated 

sample over the 4-hour period may be taken and analyzed or grab samples at" 

1-hour intervals may be taken, analyzed, and averaged. For the moisture 

content, two samples of at least 0.10 dscm (0.35 dscf) and 10 minutes shall 

be taken at the beginning of the 4-hour run and near the end of the time 

period. The arithmetic average of the two runs shall be the moisture 

content for the run. 

(d) To comply with § 60.646(d), the owner or operator shall obtain 

the information required by using the monitoring devices in paragraph (b) 

or (c) of this section.

80. Section 60.675 is revised to read as follows: 

§ 60.675 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 alternativemethods and procedures are given in paragraph (e) of this section. 

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

particulate matter standards in § 60.272(a) as follows: 

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

matter concentration. The sample volume shall be at least 1.70 dscm 

(60 dscf). For Method 5, if the 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 

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

Section 2.1) must be followed. 

92 
P.97 

(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 
P.98 

(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). 

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

concentration (Ct) and the volumetric flow rate (QSd) of the effluent gas. 

The sampling time and sample volume shall 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 (Pi) 

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

The individual glass pull rates (Pi) shall be computed using the 

following equation: 

Pi = K' Ls

 wm M [1.0 - (L0I/100)] 

where: 

Pi = 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/m2 (lb/ft2). 

LOI = loss on ignition, weight percent. 

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

[3 x 10"2 (min-ton)/(hr-lb)].

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

LOI 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.
