- 984 -1484 October 17,2014 Karen Smith Air Management Services 321 University Avenue, 2nd Floor, Philadelphia, PA 19104 Re: Department ofPublic Health Air Management Services (AMS) Reasonably Available Control Technology (RACT) State Implementation Plan (SIP) Revision under the 19978-Hour Ozone NationalAmbientAir QualityStandards (NAAQS) Dear Ms. Smith: / Thank you for the opportunityto comment onthe September 18, 2014 proposed SIP revisionthat would update Philadelphia's RACT demonstration for the 1997 8-hour ozone National Ambient Air Quality Standards (NAAQS). Modeling has shown that emissions from Philadelphia affect the air quality in New Jersey. Given the significant impact ofPennsylvania NOx emissions on NewJersey, the PhiladelphiaRACT limits for NOx should beno less stringentthan RACT limits NewJersey adopted in 2009, over 5 years ago. New Jersey disagrees with the cost per ton that AMS has selected as the threshold for economic feasibility. AMS has proposed a cost per ton of greater than $2,500 as not being reasonable. New Jersey cost of NOx control per ton of NOx removal in our 1009 RACT rules was considerably higher, approaching $50,000 per ton for peaking units. Since peaking units (also referred to as high**e~ergy** demand day units) operate mostly on hot summer days, which tend to be high ozone days, it's especially important these be controlled. Use ofan annualized $/ton metric fails to account for the cost effectiveness of controlling such electrical generating units which operate infrequently, but do so onhigh ozone days. Ifa peaking unit only operates on 

### 10 potentially high ozone days per year, the air quality value per ton ofNOx reduction is 30 times higher than abase load unit that operates 300 days peryear. Utility Boilers The attached Table 1 is a comparison ofthe proposed NOx MCT emission limits to the 2009 NewJersey RACT limits for utilityboilers. Compliance with several ofthe proposed emission limits in the table is solely based on annual stack tests. New Jersey RACT rules require all utility boilers to continuously monitor NOx emissions using a CEMS.

New Jersey isan Equal OpportunityEmployer I PrintedonRecycledPaperalldRecyclablePage 2 Comment letter to Karen Smith, AMS, Philadelphia

Some ofthe emission limits inthe table are based on a 30 day rolling average compliance period for CEMS. A 24 hour compliance period is more appropriate because it will ensure low NOx emissions onhigh ozone days, whereas limits that are based on 30 day rolling average could allow higher emissions to be emitted on high ozone days. New Jersey has already adopted 24 hour emission limits for all its utilityboilers withNOx continuous emission monitors.

. , As can be seen in Table 1, all four boilers at Veolia Energy Philadelphia Edison Station,with emission limits of0.5 IblMMBTU for NOx significantly exceed the New Jersey RACT limit of 0.2 Ib/MMBTU (2.0 IbIMWhr) for heavy oil. The emission limits of 0.35 IblMMBTU and 0.36 Ib/MMBTU for the 2 boilers at the Veolia Energy

- Schuylkill Station also exceed the New Jersey RACT limit of 0.2 Ib/MMBTU (2.0 Ib/MWhr) for heavy oiL While the natural gas emission limit for the boiler at Grays Ferry Cogeneration is equivalent to the New Jersey RACT limit, the No.2 fuel oil emission limit is 50% higher than New Jersey's limit. Based on the above comparison, we recommend that Air Management Services lower the proposed RACT emission limits for these utility boilers to be no less stringent than NJ RACT limits, require NOx CEMS on all utility boilers, and adopt a 24 hour compliance period for CEMS. Industrial Boilers The attached Table 2 is a comparison ofthe proposed NOx RACT emission limits to the New Jersey RACT emission limits for industrial boilers. The proposed NOx limits for the four industrial boilers greater than 100 MMBTUIhr in Table 2 are well above the New Jersey RACT,emission limits. Their emission limits range from 0.2 Ib/MMBTU for natural gas to O.35IbIMMBTU for No.6 fuel oil. New Jersey's RACT limits are 0.1 IblMMBTU for natural gas and 0.2 IblMMBTU for No.6 fuel oil. Three ofthe boilers that burn No.6 fuel oil have a NOx limit ofOAlbIMMBTU. New Jersey's NOx RACT limit for No.6 fuel 011 is 0.2 IbIMMBTU. Based on the above comparison, we recommend that Air Management Services lower the proposed RACT emission limits for these industrial boilers to be no less stringent than NJ RACT.1 "
