Dear Reg Neg Committee Member: 

Since the March 6, 1991 announcement of the agreement on the 

negotiated regulation for equipment leaks, Rick and I have 

received comments on several technical and drafting errors in the 

equipment leak regulation. Since the draft HON may be released 

for proposal soon, we would like to correct these errors before 

the rule is proposed for comment. The comments and the 

recommended corrections to the regulation are: 

(1) In §63.174 (h)(1), inaccessible, glass, or glass-lined 

connectors are exempted from the monitoring and from the 

recordkeeping and reporting requirements provided that they are 

designated as described in §63.181 (i)(4). Questions have arisen 

regarding the intended requirements because §63.181 (i)(4) does 

not exist and to require records designating these connectors is 

inconsistent with the text of the paragraph. 

To answer this question, I reviewed drafts of the regulation 

from July 1990 through October 1990 and found that a paragraph 

§63.181(i)(4) existed in the August 16 and 29th drafts. The 

paragraph was deleted in the Sept 26, 1990 draft in response to 

comments that it was inconsistent with the provisions in 

§63.174(h)(1) that inaccessible connectors are exempt from 

recordkeeping and reporting requirements. Apparently, the need 

to correct §63.174(h)(1) was overlooked. 

Since it appears that the intent was to not have any 

recordkeeping requirement for these connectors, I believe that 

these paragraphs should be corrected to avoid further questions 

and concerns. The changed pages 44 and 94 are enclosed. 

(2) The equation given for calculation of response factors 

of mixtures, §63.180 (b)(6)(v), is incorrect, and needs to be 

revised to make response factor calculations for mixtures 

consistent with those for single compounds. The equation for 

estimating response factors for mixtures should have read: 

n 

RFav8 = [ s (xJRFi ] _ 1 

i = l 

where : 

RFav8 = Response factor of mixture 

QH 
• _ 

/ 

n = Number of components in mixture 

xt = Mole fraction, or volume percent if in 

gaseous form, of organic compound i in the 

mixture (process stream) 

RFi = Response factor of the instrument to organic 

compound i at 500 ppm. 

Enclosed are copies of two letters received on this matter 

and page 2-28 from the draft revision of the Equipment Leaks 

Protocol document showing the correct form of the equation. 

(3) There are errors in CAS numbers and the chemical names 

in §63.183 list of hazardous air pollutants and the list of SOCMI 

chemicals in §63.184. We are correcting the errors in CAS 

numbers and the chemical names in §63.183 to be consistent with 

the list of hazardous air pollutants that will be added to 

Subpart C of Part 63. We are also recommending that the CAS 

numbers and chemical names in the chemical product list in 

§63.184 be corrected. 

In addition, the SOCMI chemical list in §63.184 has 

duplicative listings of some chemicals, separates isomers of some 

chemicals into different groups, and lists chemicals that do not 

have HAP's in the process. Furthermore, the list does not 

include several chemical products that are listed in §63.105 

which defines the applicability of the provisions for the other 

emission points. The differences between the two lists arose 

because an early draft of the HON chemical list was used to 

create the list in §63.184. As information was developed in the 

HON project, many of the chemicals in the early draft of the list 

were discovered not to have HAP's in the process and were 

subsequently dropped from the list. I believe that it would be 

desirable to use the same list of chemicals to define 

applicability of the HON. Therefore, I recommend that the 

chemical list be modified to make the equipment leaks portion of 

the rule consistent with the rest of the package. Alternatively, 

we could take comment on these changes and revise the list after 

proposal. 

The enclosed copy of §63.184 is annotated to show the 

recommended corrections and the reasons for the recommendation. 

Corrections to the chemical name, CAS number or labels are shown 

in Redlifte and suggested deletions are indicated by Strikeout. 

In summary, the proposed changes would: 

o Delete duplicative listings of 5 chemicals. The 5 

chemicals are listed now under the earliest of their 

assigned groups. 

i-i-ti.i..i---«i-.---^i------------i--^^ ., ,±iiimmimm**M»*m*mmi 
•f 

o Move m-xylene from Group III to Group I to put all the 

xylene isomers in one group and move o-chlorophenol 

from Group III to Group II to put all the chlorophenol 

isomers in one group. 

o Delete 85 chemical manufacturing processes that do not 

use an organic HAP as a reactant or produce an organic 

HAP as a product from the Groups as follows: 

4 from Group I 

21 from Group II 

19 from Group III 

9 from Group IV 

32 from Group V 

o Add 35 chemical manufacturing processes to the list. 

These are listed in Enclosure 5. 

We believe these are reasonable changes to avoid unnecessary 

confusion and to avoid imposing recordkeeping costs where the 

standard would not be relevant. In addition, by correcting errors 

in chemical names, CAS numbers, and unnecessary differences in 

applicability, there will be less confusion over applicability 

and the administrative burden. 

Also enclosed are minor editorial corrections to pages 15, 

42, and 78 of the regulation to cite applicable sections in Part 

63 and correct other bugs. 

All of these changes are intended to correct technical or 

editorial errors and do not change the substance of the standard. 

,j If anyone has strong feelings about these changes, please contact 

j| Rick or me. If we do not hear from you by Oct 16th, we will 

j, assume that you agree with the changes and that we can 

j incorporate the changes in the negotiated rule. As usual, a copy 

of this package and any responses received will be included in 

the negotiation docket. 

In the meantime, we will be completing the editorial changes 

to the preamble and preparing to send out the final preamble and 

agreement for signature. As always, feel free to contact me or 

Rick if you have any questions on status. 

Sincerely, 

/7?«

Dear Dr. Meyer, 

You may have received a fax last Friday regarding ACS's 

interpretation of an average response factor formula. The formula 

appeared in the NESHAP Announcement of Negotiated Regulation for 

Equipment Leaks, published in the Federal Register, March 6, 

1991. The purpose of this letter is to provide a more general 

description of the situation which leads to ACS's confusion 

regarding the average response factor formula. 

As an example, as 

volume concentrat 

response factor o 

compound B is 10. 

rate of 600 ppm, 

is used to monito 

response characte 

read from the met 

sume that there is a binary gas, with 50 percent 

ions for each of two compounds, A and B. The 

f compound A is 1, and the response factor of 

Given that a particular device is leaking at a 

or 300 ppm of A and 300 ppm of B. An OVA meter 

r the device, and, based on the individual 

ristics of the compounds, a value of 330 ppm is 

er. This situation is summarized as:

The formula shown page 9331 of the Federal Register gives an 

average response factor of:

P.12 

This RFavg value would overestimate the leak as 330 * 5.5 = 1815 

ppm. An alternate formula for average response factor gives the 

value shown below: 

pP.-T-~_ Si-***ci> _ 504-50 _ 100 _ -| p-ip-i 

Rkavg- n Iti(*^x^i . -) sonvt-sofo.i. ~ T T ~ -L.»l«l 5°(1>

+50(0-1) 

This RFavg value gives the expected result of 330 * 1.8181 = 600 

ppm. 

We recognize that this is a proposed regulation and we are not 

asking for official comment. If we are in error, we would 

appreciate your correction. Thank you for your consideration. 

Sincerely, 

Nathan E. Cook

Dear Jan, 

As we have already discussed, the mixture response factor calculations in the draft equipment 

leak MACT should be modified. A revision is necessary to make the response factor calculations 

consistent for single compounds and for mixtures. The approaches enclosed here have been 

experimentally verified. I trust you will make appropriate changes to the draft equipment leak 

MACT. 

In the past, there has not been uniformity in the way response factors have been determined 

by various manufacturers. Some have used 

Response Factor = Right Answer 

Wrong Answer 

When this practice was used 

Actual concentration = (Response Factor) (Meter reading) 

and 

1 = Mole Fraction A + Mole Fraction B + . . . 

Multiple Compound Response Response Factor A Response Factor B 

Factor 

Others have used the reciprocal response factors or 

Response Factor = Wrong Answer 

Right Answer 

Leading to the following calculation procedures 

Actual Concentration = Meter Reading 

Response Factor 

and 

Multiple Compound Response Factor = (Mole Fraction A) (Response Factor A) 

+ (Mole Fraction B) (Response Factor B) + ... 

TAK

April 23, 1992 

Jan Meyer 

Both approaches are correct and give exactly the same corrected concentrations for individual 

compounds and for mixtures. Some test data were collected by a CMA member company to see 

how good the calculated mixture response factors actually are. The comparisons for two types 

of instruments are tabulated in the attached. Excellent agreement is shown for the mixtures 

tested. It appears that the methods above give a good estimate of the combined response factors 

when the vapor molar concentrations are known. 

[An assumption that can be made for liquid-vapor systems is that the gas 

phases in association with such liquids have the same molar compositions as the liquids. This 

assumption of ideality may not be true but is true for some systems.] 

Unfortunately, the above procedures are apparently mixed in the draft regulations. This could 

be corrected by either defining the individual response factor as needed or by changing the 

mixture calculation to work for the implied response factor. I believe the latter would be more 

appropriate. 

Response factor does not appear to be defined in the draft. Therefore, it could be defined to 

give correct mixture calculations using the mixture equation in the draft. Such a definition 

would go against the implied use of response factors. I.e. Instead of requiring response factor 

below 3.0, factors above 0.33 would be mandated. 

I believe it would be best to settle on the opposite convention, which people seem to favor 

instinctively. I.e. 

define Response Factor = Right Answer 

Wrong Answer 

then the appropriate calculation for mixtures would be: 

1 = Mole Fraction A + Mole Fraction B + ... 

Mixture Response Factor Response Factor A Response Factor B 

If you have any questions or wish to discuss this further, please give me a call.

DRAF T 

AC = Actual concentration of the VOC (ppmv); and 

SV = Screening value (ppmv). 

The value of the RF is a function of several parameters. 

These parameters include the mohitoring instrument, the 

calibration gas used to calibrate the instrument, the 

compound(s) being screened, and the screening value. 

When using screening values to estimate equipment leak 

mass emissions, it may be necessary to account for the RF. A 

detailed listing of RF*s is contained in Appendix C. These 

RF's were developed by injecting a known concentration of a 

pure compound into a monitoring instrument and comparing that 

actual concentration to the instrument readout (i.e. screening 

value). As an example of applying a RF, consider toluene. 

From Table C-2 in Appendix C, it can be seen that the RF of a 

Foxboro OVA-108 monitoring instrument for toluene at an actual 

concentration of 500 ppmv is equal to 0.87. Thus, when the 

actual concentration of toluene is 500 ppmv, the instrument 

will read 500 ppmv divided by 0.87, which equals 575 ppmv. 

The response factors in Appendix C are for pure 

compounds. Those response factors can be used to estimate the 

response factor for a mixture using the following equation: 

RFm = 

n 

£ t*i/RFi) 

i=l 

-1 

where: 

RF 

n 

x 

m = Response factor of the mixture; 

= Number of components in the mixture; 

= Mole fraction of constituent i in the mixture; 

and 

RFi = Response factor of constituent i in the mixture.

29965977 Cyclooctadienes 

The reg neg SOCMI list includes the first 2 of these numbers in 

Group II but incorrectly identifies the chemical names (see p.6). 

(1) Are 1,5-Cyclooctadiene and (Z,Z)-Cycloocta-l,5-diene the 

same chemical? Are they both manufactured using butadiene? 

(2) Did the Committee intend to list the 1,3-isomer 

(CAS # 1700103) which is also manufactured from butadiene? 

(3) Did the Committee intend to list the CAS number for "all 

isomers" or "mixed isomers"?

Styrene-butadiene rubber production means a process 

that produces styrene-butadiene copolymers, whether in solid 

(elastomer) or emulsion (latex) form. 

f: 

Volatile hazardous air pollutant or VHAP means a 

substance listed in §63.183. 

§63.162 Standards: General. 

(a) Each owner or operator subject to the provisions 

of this Subpart shall demonstrate compliance with the 

requirements of §§63.162 through 63.174 for each new and 

existing source as required in 40 CFR 61.05 of this chapter, 

except as provided in §§63.175 and G3.17G. through 63,179* 

(b) Compliance with this Subpart will be determined by 

review of records, review of performance test results, and 

inspection using the methods and procedures specified in 

§63.180. 

(c)(1) An owner or operator may request a 

determination of alternative means of emission limitation to 

the requirements of §§63.163 and 63.164, §§63.166 through 

63.170, and §§63.172 through 63.174 as provided in §63.177. 

(2) If the Administrator makes a determination that a 

means of emission limitation is a permissible alternative to 

the requirements of §§63.163 and 63.164, §§63.166 through 

63.170, and §§63.172, 63.173, or 63.174, the owner or 

operator shall comply with the alternative. 

(d) Each piece of equipment in a process unit to which 

this Subpart applies shall be identified such that it can be

connector credits as described in paragraph (i) of this 

section. 

(c)(1)(i) Except as provided in paragraph (c)(1)(ii) 

of this section, each connector that has been opened or has 

otherwise had the seal broken shall be monitored for leaks 

within the first 3 months after being returned to VHAP 

service, including those determined to be nonrepairable 

prior to process unit shutdown. If the follow-up monitoring 

detects a leak, it shall be repaired according to the 

provisions of paragraph (d) of this section, unless it is 

determined to be nonrepairable, in which case it is counted 

as a nonrepairable for the purposes of paragraph (i)(2) of 

this section. 

(ii) As an alternative to the requirements in 

paragraph (c)(1)(i) of this section, an owner or operator 

may choose to calculate percent leaking connectors for the 

monitoring periods described in paragraph (b) of this 

section, by setting the nonrepairable component, -&$-, f|$|| 

in the equation in paragraph (i)(2) of this section to zero 

for all monitoring periods. 

(iii) An owner or operator may switch alternatives 

described in paragraphs (c)(1)(i) and (ii) of this section 

at the end of the current monitoring period he is in, shall 

provided that he notify the Administrator as required in 

63.182(b)(7) and begin the new alternative in annual 

monitoring. The initial monitoring in the new alternative
