Re: Department of Public Health Air Management Services (AMS) Reasonably Available 

Control Technology (RACT) State Implementation Plan (SIP) Revision under the 19978-Hour 

Ozone National Ambient Air Quality Standards (NAAQS) 

Dear Ms. Smith: 

/

Thank you for the opportunity to comment on the September 18, 2014 proposed SIP revision that 

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 of Pennsylvania NOx emissions on 

New Jersey, the Philadelphia RACT limits for NOx should be no less stringent than RACT limits 

New Jersey 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 of an annualized $/ton 

metric fails to account for the cost effectiveness of controlling such electrical generating units 

which operate infrequently, but do so on high ozone days. If a peaking unit only operates on 10 

potentially high ozone days per year, the air quality value per ton of NO x reduction is 30 times 

higher than a base load unit that operates 300 days per year. 

Utility Boilers 

The attached Table 1 is a comparison of the proposed NOx MCT emission limits to the 2009 

New Jersey RACT limits for utility boilers. 

Compliance with several of the 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.

Comment letter to Karen Smith, AMS, Philadelphia 

Some of the emission limits in the 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 on high 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 utility boilers with NOx continuous emission monitors. . , 

As can be seen in Table 1, all four boilers at Veolia Energy Philadelphia Edison Station, with 

emission limits of 0.5 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 of the 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 of the 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.
