A dina@epamail.epa.gov; V i j ayan. A bi@epamail.epa.gov; Robinson.Jeffrey@epamail.epa.gov Subject: Request for Additional Information - Historical Data RE: Section 219 Technical Revisions

As discussed during our call yesterday, we are requesting additional information to be included as part of our record for the review of the proposed SIP Revisions to incorporate the Section 219 Permit Revisions provisions contained in Part 72.

We request the following information from NMED:

(1) Additional Historical Permit Actions Information The total number of permit actions taken by NMED each year for 1991 - 2012 that resulted in the  issuance of an Initial Major NSR Permit. The total number of permit actions taken by NMED each year for 1991 - 2012 that resulted in the  issuance of an Initial Minor NSR Permit. If the database used by NMED does not allow for initial permit actions to be easily distinguished between Minor and Major actions, we would request the total number of initial NSR permits issued each year in place of the data divided between Major and Minor actions.

(2) Annual Emissions Increases Authorized Under Section 219 Technical Revisions The total amount of increases in permitted emissions authorized via Technical Permit Revisions  for 2009, 2010, and 2011 for the following NAAQS pollutants (or precursors in the case ofozone): CO o Pb o NOx o VOC o PM10 o PM2.5 o SO2 o



###  (3) Emissions Increases Authorized under Technical Revisions Associated with Increased in Permitted Emissions Based on Compliance Testing Results For each Technical Revision issued in 2009, 2010, and 2011 that authorized emissions increases  via the 10% increase allowance based on initial compliance testing (20.2.72.219(B)(1)(e) NMAC), the increases in permitted emissions for the following NAAQS pollutants: CO o Pb o NOx o VOC o PM10 o PM2.5 o SO2 o



### o

To add additional clarity to our request, I have attached a spreadsheet containing three tables showing the specific information we are requesting. The first table is based off of the information from Table 2 that was included in NMED's September 19, 2012 letter (RE: Clarification of Exemptions in Section 202 of 20.2.72 NMAC - Construction Permits) to Tom Diggs. The third table's size will be adjusted based on the number of Technical Revisions that are identified that were authorized under the 20.2.72.219(B)(1)(e) NMAC Technical Revision.

If you have any questions regarding our request, do not hesitate to contact me. Also, please provide an estimate of the amount of time required to provide this information. If you are unable to provide any portion of the requested information please let me know as soon as possible so that we can adjust the request, as necessary.

Thanks for your assistance,

Ashley
