Ashley,

Attached is the spreadsheet identifying all active sources in the Tempo AQB dataset. 

In the interest of time, I have not reviewed all 17763 entries, but you should be aware 

that a single entry may represent a number of identical sources (e.g., an 

owner/operator may include 75 identical portable compressors under a single Notice 

of Intent). For the purposes of your review, let us use 17763 as the number of active 

sources plus the estimated 2000 sources exempt under Part 72 for a total of 19763 

sources under NMED’s jurisdiction. The exempt sources comprise approximately 10% 

of this total. If we were to account for the multiple sources in Tempo, it is safe to say 

that the exempt sources are less than 10% of the total number of sources in the 

system.

Should you require additional information, please do not hesitate to contact me.

Regards,

Kerwin

Ashley,

I received a preliminary data set late yesterday, but it needs to be refined to limit the query to 

the AQB files only. I should have something later today.

Kerwin,

Thanks again for your assistance. Once you have spoken with your IT contact and have an idea of the 

time frame required to get this data, could you let me know? My response to management on this 

question is time sensitive so I would like to provide an estimated time frame to them as soon as possible. 

Just so you are aware of my time frame, a response providing the total number of active units in 

comparison to the exempted sources number by the end of this week would be ideal.

Thanks again!

Ashley

Ashley, 

The 2000 estimated units was determined from the spreadsheet I forwarded to you on 

09/25/12. As indicated in the SI_DESCRIPTION column, one TEMPO entry may cover multiple 

units. That list covered all active units in TEMPO as of 09/13/12. If this requires additional 

explanation, please let me know.

Thanks,

Kerwin

Kerwin,

Can NMED supply a total number of currently active units based on the NMED TEMPO permitting 

database? We would like to understand how the "2,000 active units that may have been subject to 

exemptions" under Part 72, Section 202 compares with the total number of currently active units in New 

Mexico.

Thanks in advance for your help. Let me know if you have any questions regarding my request.

Ashley

Kerwin,

You were listed as the staff contact on the Part 72 clarification letter regarding permit exemptions, so I am 

reaching out to you regarding a follow-up question I had after reviewing the letter. 

Based on my understanding of the letter, the "excess of 2,000 active individual units" accounts for the 

multiple units included in the total of 942 subject items for the 4 different categories referenced in the 

letter (Backup/Standby, Emergency, Exempt, Insignificant). Do you have information regarding the 

number of individual active units for each of the 4 categories. I am trying to get an idea of how many of 

the 2,000 active individual units did claim an exemption. I assume that those sources in the Exempt 

category in the database would reflect this information. I understand that this would not include all 
sources that utilized an exemption under Section 202, since all exemptions do not require notification 

under the provisions of Part 72 in addition to any sources that may not have been entered into the 

database.

Thanks in advance for your help. Feel free to give me a call if you have any questions.

Ashley
