Under the Clean Air Act, the most stringent emission limitation derived from either (1) the most stringent emission limitation in the implementation plan of any state for such source or category of source; or (2) the most stringent emission limitation achieved in practice by such class or category of sources.
A requirement applying to proposed new or modified major stationary sources of pollution in nonattainment areas. LAER means the "rate of emissions that reflect the most stringent emission limitation contained in the SIP of any state for such class or category of source or the most stringent emission limitation which is achieved in practice . . . whichever is more stringent."
The degree of emissions control required on new major sources and major modifications in nonattainment areas. The technology must be the best in use or most stringent in any SIP (State Implementation Plan) and cost is not taken into account.
This represents the most stringent control technology achieved in practice regardless of cost. LAER is used to determine emission limits for the NSR program.
The most up-to-date methods, systems, techniques, and production processes available to achieve the greatest feasible emission reductions for given regulated air pollutants and processes. Federal LAER determination does not consider cost effectiveness. (Compare to BACT.)
The air emission rate that is the lowest possible for a type of facility for a specific pollutant; required of air pollution sources in air quality nonattainment areas.
That emission rate, required for air pollution sources in air quality nonattainment areas, which is the lowest possible for the type of facility for the specified pollutant.
The rate of emissions which reflects the most stringent emission limitation which is contained in the NY SIP or, the most stringent emission limitation achieved in practice, whichever is more stringent. CAA ยง 171(3).
Under the Clean Air Act, the rate of emissions that reflects (1) the most stringent emission limitation in the implementation plan of any state for such source unless the owner or operator demonstrates such limitations are not achievable; or (2) the most stringent emissions limitation achieved in practice, whichever is more stringent. A proposed new or modified source may not emit pollutants in excess of existing new source standards.
