§203.210. Relaxation of a Source-Specific Limitation

a)         No person shall cause or allow the operation of a source so as to exceed any enforceable limitation which affects or defines the applicability of the requirements of this Part to a stationary source or modification by specifying the permissible emission rate, operating hours, the type or amount of material processed, stored or combusted, or other aspects of source operation.

 

b)         At such time that a particular source or modification becomes a major stationary source or major modification solely by virtue of a relaxation in, or expiration of, any enforceable limitation which was established after August 7, 1980, on the capacity of the source or modification otherwise to emit a pollutant, such as a restriction on hours of operation, then the requirements of this Part shall apply as though construction had not yet commenced on the source or modification.
