requirement was scheduled to be promulgated
pursuant to section 112(e)(3).
c. Any HAP subject to a District case-by-case
emissions limitation determination for a new
or modified source, prior to the U.S. EPA
promulgation or scheduled promulgation of an
emissions limitation shall be considered a
regulated air pollutant when the
determination is made pursuant to section
112(g)(2). In case-by-case emissions
limitation determinations, the HAP shall be
considered a regulated air pollutant only for
the individual source for which the emissions
limitation determination was made.
