Subject: 1997 8-Hour RACT Analysis for University of Pennsylvania 

Introduction: 

The Clean Air Act (CAA) requires that moderate (or worse) ozone nonattainment areas implement reasonably 

available control technology (RACT) controls on all major sources of VOC and NOx. Philadelphia County is part of 

the Philadelphia-Wilmington-Atlantic City moderate ozone nonattainment area for the 1997 8-hour ozone NAAQS. 

This document presents the findings of a RACT evaluation for the 1997 8-hour ozone standard for this facility. 

Company Description: 

The University of Pennsylvania is located at 3451 Walnut Street, Philadelphia, PA 19104. The facility’s air 

emission sources include nine (9) heaters and furnaces rated less than 10 MMBTU/hr, 56 emergency generators and 

two fire pumps. In the past, the facility operated a 2000kW diesel peak shaving generator with a Selective Catalytic 

Reduction Device, but has been out of service and removed from the facility a few years ago. 

Applicability for NOx and VOC RACT: 

The University of Pennsylvania is a major source of Nitrogen Oxides (NOx) having potential NOx emissions greater 

than 100 tons per year, the major source threshold in Philadelphia County that is applicable to NOx RACT for the 

1997 8-hour ozone NAAQS. 

The University of Pennsylvania is not a major source of Volatile Organic Compounds (VOC) having potential VOC 

emissions less than 50 tons per year, the major source threshold in Philadelphia County that is applicable to VOC 

RACT for the 1997 8-hour ozone NAAQS. 

Process Descriptions: 

The facility’s air emission sources contributing to NOx emissions include the following: 

 Nine (9) heaters and furnaces rated less than 10 MMBTU/hr each burn natural gas; 

 15 emergency generators with capacities ranging between 75 kW - 750 kW that each burn natural gas; 

 41 emergency generators with capacities ranging between 150 kW – 1,750 kW that each burn diesel; 

 Two (2) fire pumps with capacities ranging between 150 hp – 187 hp each burn diesel; 

Presumptive RACT: 

The following sources are covered by presumptive RACT 25 Pa Code 129.93 (c)(1) (heaters & furnaces) or 25 Pa 

Code 129.93 (c)(5) (fire pumps & emergency generators). For each of the following sources, the presumptive RACT 

emission limitation is the installation, maintenance, and operation of each source in accordance with manufacturers’ 

specifications.
