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

Melanie,

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

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.

Eleonora

>>> <King.Melanie@epamail.epa.gov> 9/2/2009 11:42 AM >>> 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.

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 10:0 9:21 AMfile:///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

>>> <King.Melanie@epamail.epa.gov> 5/7/2009 11:39 AM >>> 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.

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 10:0 9:21 AMfile:///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,
