Lack of PPM data plus suggestions for improvement

Currently there exists no incentive for manufacturer's to publish PPM NOx. Although they have to do is to run some tests, and verify that it is below the SQAMD action levels, to comply with CA requirements. As a result I can only put in 55 and 30 for my two boilers, since that is the testing threshold used. Which is a shame. Projects should be able to: 1. Allowed to trade off between NOx emitters if required, provided that the overall ppm/BTU emitted is below the action levels. Allow flexibility for projects that may feature legacy equipment that cannot be removed, or may require specialty combustion devices like gas flares, etc... 2. Give extra points in terms of exemplary performance for projects whose overall weighted emissions/BTU is below the SQAMD levels. 1 point for 50% below. 2 points for NOx levels below 1 ppm. These are my ideas, let me know other people think.

I agree. We had a heck of a time getting this data from LG.

A cut sheet that I just reviewed for a natural gas hot water boiler has the NOx in PPM listed right on the front of the cut sheet. Maybe I am lucky.

I would agree. I had a really hard time finding NOx data for the boilers and generator we are using on a current project, had to contact the manufacturer and get transferred around until someone knew what I needed.

On my project, the generator's manufacturer Statement of Exhaust Emissions was measured in in grams/kW-hr, but fortunately, they also have a SCAQMD CEP number.

I had a project within SCAQMD, and the generator met SCAQMD rules. (It had to to be permitted). However, the project was denied this credit even upon appeal, due to the lack of NOx information. Review comment: "The credit language specifically indicates the maximum emission rates of stand-by or emergency engines (11 ppm NOx, 30 ppm VOC, 70 ppm CO). The Pilot Credit is intended to be more stringent than the reference standard.....the credit remains denied".

I can only find general pilot documentation requirements for this credit which includes registering for the credit, participating in the LEEDuser forum and completing the survey. Are there any other documentation requirements? If so, where can I find them? Thank you

There are no other listed documentation requirements; however, including cut sheets for all combustion equipment within the project that list the emission levels, as well as narrative summarizing the information is probably your best bet.

We experience a similar issue converting Lbs/hr to ppm but were able to go back to the testing agency and request the data in ppm. They converted this value and provided it back to us. I suggest having the BAAQMD, SCAQMD or similar test and provide the permitting documentation in both Lbs/hr and PPM tested during the 15 minute interval. Alternatively having a handheld monitor/sensor may behoove the engineering team to verify the AQMD's measurement.
