Section 203
Section 203.210Â Relaxation
of a Source-Specific Limitation
a)Â Â Â Â Â Â Â Â 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)Â Â Â Â Â Â Â Â 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.
