          1.   Incorporation of Federal Standards.
               The provisions of Part 60, Chapter I, Title 40 of the Code
               of Federal Regulations (40 CFR Part 60), which are in effect
               on February 20, 1991, are incorporated herein as part of the
               Rules and Regulations of the Monterey Bay Unified Air
               Pollution Control District.  Applicable provisions of 40 CFR
               Part 60 include those incorporated in the current bound CFR
               volume plus any provisions recently promulgated by EPA, as
               noticed in the Federal Register, but not yet incorporated
               into the bound CFR.  Where there are currently effective
               provisions which are not yet included in the bound CFR
               volume, the Federal Register notice by which each provision
               was promulgated is referenced at the affected subpart in
               Appendix A of this Rule.


          2.   Applicability.
               All new stationary sources of air pollution, and all
               modified or reconstructed stationary sources of air
               pollution shall comply with the standards, criteria, and
               requirements set forth herein.  Whenever any source is
               subject to more than one rule, regulation, provision or
               requirement relating to the control of any air contaminant,
               the most stringent provision shall apply.


          3.   "Administrator" means "APCO".
               For the purpose of this Rule, the word "Administrator" as
               used in 40 CFR Part 60 shall mean the Air Pollution Control
               Officer (APCO) of the District, except where the reference
               to "Administrator" relates to approval of alternate or
               equivalent test methods or alternative work practices.


          4.   List of Incorporated CFR Provisions.
          The following table lists all 40 CFR Part 60 provisions which are
               incorporated in their entirety as part of this Rule. 
               Federal Register (FR) references are to currently effective
               provisions promulgated or revised by EPA but not yet
               incorporated into the currently available CFR volume. 
               Notations in this list indicate deviations from the
               EPA-promulgated provision found in the CFR which have been
               adopted by the District Board for inclusion in this Rule.
