Pennsylvania's War Against Smog

1. Fossil fired combustion units with rated heat input capacity of 250 MMBtu per hour or more.

2. Electric generating facilities of 15 megawatts or greater.

3. Stationary reciprocating internal combustion engines.

4. Cement manufacturing operations. Chapter 145 Interstate Ozone Transport Reduction differs from the current program in the following ways:

5. The new rule requires emission reductions greater than the reductions required by Chapter 123.

6. Under the existing program in Chapter 123, individual NOx emission sources are listed in Appendix E along with the number of NOx allowances. Chapter 145, on the other hand, establishes a formula for calculation of NOx allowances in §145.42. This formula is based on an emission limitation expressed as an emission rate times the heat input or usage of the NOx budget unit. The heat input number is derived from data submitted by the NOx budget source. The new program is scheduled to begin in 2003 and will replace the existing NOx allowance requirements contained in Chapter 123. However, a May 1999 ruling by a three-judge panel of the U.S. Circuit Court of Appeals has ordered EPA to delay the SIP call deadline pending the outcome of a lawsuit involving several Midwestern states and utilities.
