The RACT Plan Approved is subject to the following conditions: 

1. The purpose of this Plan Approval is to establish Nitrogen Oxides (NOx) Reasonably Available 

Control Technology (RACT) for PECO – Richmond (Exelon). This includes the following 

emission sources and control equipment: 

 A. Emission Sources 

(1) Two General Electric Frame 7B combustion turbines, each burns #2 oil and 

kerosene. The nominal output for each is 66 MW. 

2. This Plan Approval authorizes: 

A. The implementation of the following operational limitations on the two Richmond 

combustion turbines to comply with the case-by-case determination in the RACT proposal 

submitted by PECO Energy Co. (Exelon): 

(1) Maximum 12-month rolling capacity factor less than 15% for each combustion 

turbine. 

The rolling 12-month capacity factor is expressed as: 

 Last 12 months net generation (MWH) 

 ----------------------------------------------------------------------------------------------------

- 

 Maximum capacity of unit (MW) x 24 hrs/day x No. of days in last 12 months 

(2) The installation, maintenance and operation of the combustion turbines in 

accordance with manufacturers specifications. 

3. RACT Implementation Schedule 

A. Upon issuance of this Plan Approval, PECO (Exelon) shall begin immediate 

implementation of the measures necessary to comply with the approved RACT proposal. 

4. Monitoring Requirements 

A. Combustion Turbines: Daily fuel usage, and net generation for each combustion turbine on 

a monthly basis. Rolling 12-month capacity factor for each combustion turbine, calculated 

on a monthly basis. 

B. Exelon – Richmond shall perform an AMS-approved stack test on one combustion turbine 

every 5 years to demonstrate compliance with the NOx emission limits in Condition 5.A. If 

the test results are above 0.34 lbs/MMBTU or 284.92 lbs/hr (50% of the limits), the other 

combustion turbine shall also be tested during that 5-year period.

5. Emission Limitations 

A. Each combustion turbine listed 1.A.(1) above shall limit its NOx emissions to no more 

than 0.68 pounds per MMBtu and 569.84 pounds per hour. 

6. Recordkeeping and Reporting Requirements 

A. PECO - Richmond shall maintain a file containing all the records and other data that are 

required to be collected to demonstrate compliance with NOx RACT requirements of 25 

PA Code SS129.91-129.94. These records shall include records of the monitoring 

requirements of this Plan Approval. 

B. The records shall provide sufficient data and calculations to clearly demonstrate that the 

requirements of SS129.91-129.94 are met. 

C. Data of information required to determine compliance shall be recorded and maintained in 

a time frame consistent with the averaging period of the requirement. 

D. Records shall be retained for at least five years and shall be made available to AMS on 

request. 

7. The operation of the aforementioned combustion turbines shall not at any time result in the 

emission of visible air contaminants in excess of the limitations specified in Section 123.41, 

particulate matter in excess of the limitations specified in Section 123.11 or sulfur oxides in excess 

of the limitations specified in Section 123.22, all Sections of Chapter 123 of Article III of the 

Rules and Regulations of the Department of Environmental Resources, or in the emission of any 

of these or any other type of air contaminant in excess of the limitations specified in, or 

established pursuant to, any other applicable rule or regulation contained in Article III. 

8. The company shall not impose conditions upon or otherwise restrict AMSs access to the 

aforementioned source(s) and/or any associated air cleaning device(s) and shall allow AMS to 

have access at any time to said source(s) and associated air cleaning device(s) with such 

measuring and recording equipment, including equipment recording visual observations, as AMS 

deems necessary and proper for performing its duties and for the effective enforcement of the Air 

Pollution Control Act. 

9. Revisions to any emission limitations incorporated in this Plan Approval will require resubmission 

as revision to the PA State Implementation Plan. The applicant shall bear the cost of public 

hearing and notification required for EPA approval as stipulated in 25 PA Code Section 129.91(h).
