August 29, 1988 Transfer of Technology
in Determining Lowest Achievable Emission Rate (LAER) 26.5
(a) EPA supports transfer of control technology
between source categories for the purpose of determining LAER for a source
both for gas stream controls, and for process controls and modification.
(b) LAER is primarily an emissions unit determination; each emissions
unit must achieve the lowest possible emission rate. "Facility-wide" LAER
can be considered if some more effective LAER exists thereby. Three hurdles
to determining "facility- wide" LAER are discussed.
(c) LAER can be considered individually for each aspect of control
of a source, although reviewers must be aware that one decision affects
the others.
