107-0056 Final Memo (May 6. 2013).doc

Shaheerah,

A little history on the modification:

The modification to incorporate GHG into the permit was required because the source was not constructed within 18

months of permit issuance and during that time our GHG PSD regulations went into effect. The original permit required

the permittee submit a new BACT review anyway if the source was not constructed within 18 months. The modification

was done in two parts: First they submitted a BACT review, which was approved by the Department and we instructed

the permitted to submit the modification application to incorporate the approved BACT.

Attached is the re

‐ BACT for the criteria pollutants/GHG BACT review and the modified permit, and technical evaluation.

The BACT review has a bunch of hyper

‐ linked documents of submittals and requests for information, if you want to see

any of those I can send them. I think everything is basically in the evaluation anyway.

Shaheerah,

Gary Rose forwarded your request for information on the Montville biomass project. There was a major-modification

recently, May 20th, done to that permit incorporate CO2e PSD/BACT as our state rules did not exempt biomass from GHG

PSD.

Let me know if you would like both the original permit an d recent modification along with the supporting documentation

or only the original permit that you referenced in your request. Also, this plant has not been constructed at time, so none

of the emission rates have been verified.
