Melanie, 

I asked our Bureau of Technical Services about actual stack test reports from 

the companies. They say that those test reports are not in electronic format, 

and we do not have resources to make copies of large documents as those 

reports. Someone could come and make copies. 

The Bureau of Technical Services gave me the following information about test 

methods: 

For formaldehyde, Method 323. For CO, Method 10. 

I hope this information will help. 

Thanks, 

Eleonora

Thanks, I think we would need a little more information than what is in 

the summary report you attached in order to be able to use the data. We 

can use CO data as well as formaldehyde data.

Melanie, 

we have the compliance stack test summary reports for each facility that 

file:///C|/Documents%20and%20Settings/aassem01/Desk...ring/OAR-2008-0708-DRAFT-0350%20M.%20King%20(3).txt (2 of 8)2/22/2010 10:09:21 AM
file:///C|/Documents%20and%20Settings/aassem01/Desktop/For%20Rendering/OAR-2008-0708-DRAFT-0350%20M.%20King%20(3).txt

are prepared by the NJDEP Bureau of Technical Services. Attached is the 

example of such a report for natural gas fired lean burn engines (for 

Homasote). 

In New Jersey, we have only three tests for formaldehyde. One more is 

planned by the end of this year. 

I understand that you need test methods listed. I will ask our Bureau of 

Technical Services to help. I am not sure if we have those papers in 

electronic form.

Hi, 

In the NJDEP comment letter there was an attachment that provided some 

stack test results for diesel engines and natural gas 4SLB engines. 

Would it be possible for us to obtain copies of the actual test reports 

for those tests? In order for us to incorporate stack test data in our 

analysis, we typically require the test report so that we can verify the 

test methods that were use and that type of thing.

Melanie, 

here's the NJDEP comment letter. The hard copy is in the mail. We did 

not comment on emergency engines testing as we discussed, we were trying 

to make a short letter. 

Please let me know if your have any questions, 

Thanks, 

Eleonora 

>>> <King.Melanie@epamail.epa.gov> 5/7/2009 1:59 PM >>> 

I've had lots of phone calls from people asking what is the point of 

having an emission limit if you don't require a test to demonstrate 

compliance so I expect we'll get a lot of comments on that. 

Thanks, 

Melanie

Melanie, thanks for the thorough explanation. 

Eleonora 

>>> <King.Melanie@epamail.epa.gov> 5/7/2009 1:47 PM >>> 

The only compliance requirements for the emergency engines would be to 

operate and maintain the engine per the manufacturer's instructions and 

record the hours of operation. There is no test required to directly 

show compliance with the emission limit. 

One of the main reasons for not requiring testing on emergency engines 

is because the cost of the rule would be really high if we required 

emergency units to be tested, and since they don't operate very 

frequently the decision was made to only require testing for 

non-emergency engines.

 Re: Proposed MACT ZZZZ 3/5/09 

Melanie, thanks, that's very helpful. 

As to emergency engines, the proposed Table 2d line 7 and 14 have 

numerical lifts for emergency SI and CI engines. If there is no tests, 

file:///C|/Documents%20and%20Settings/aassem01/Desk...ring/OAR-2008-0708-DRAFT-0350%20M.%20King%20(3).txt (6 of 8)2/22/2010 10:09:21 AM
file:///C|/Documents%20and%20Settings/aassem01/Desktop/For%20Rendering/OAR-2008-0708-DRAFT-0350%20M.%20King%20(3).txt

then what are the means of compliance? 

Thanks, 

Eleonora

Hi, 

Emergency engines are not required to do an initial stack test. That 

sentence is misleading and probably should have read "Owners and 

operator of existing non-emergency stationary RICE . . . " 

A landfill gas engine that is >500 HP would have to do an initial test. 

It would fall under line 9 in table 5 as an existing stationary 

non-emergency RICE >=100 HP located at an area source complying with the 

requirement to limit the CO concentration. Only the area source 

landfill gas engines >500 HP have a CO limit so those are the ones that 

have to do a test.

 Proposed MACT ZZZZ 3/5/09 

Melanie, 

file:///C|/Documents%20and%20Settings/aassem01/Desk...ring/OAR-2008-0708-DRAFT-0350%20M.%20King%20(3).txt (7 of 8)2/22/2010 10:09:21 AM
file:///C|/Documents%20and%20Settings/aassem01/Desktop/For%20Rendering/OAR-2008-0708-DRAFT-0350%20M.%20King%20(3).txt

I am reviewing the proposed MACT for RICE engines, and I've got a 

question. In a preamble (FR page 9704), it is said that "Owners and 

operators of existing stationary RICE subject to numerical emission 

standards and that are located at area sources, as shown in Table 2 of 

this preamble, must conduct an initial performance test to demonstrate 

that they are achieving the required emission standards." 

My question - are emergency engines and landfill engines with numerical 

limits subject to an initial stack testing, similar to non-emergency 

engines? Emergency engines and landfill engines are not included in the 

proposed Table 5 that lists sources subject to testing. 

If no stack testing is proposed how emergency and landfill engines would 

demonstrate compliance with the limits? 

Please advise, 

Thanks,
