MEMORANDUM

SUBJECT:  Martins Creek--Requirements for Redesignation

FROM:     Dean A. Wilson, Meteorologist
          Techniques Evaluation Section, SRAB (MD-14)

TO:       Alan Cimorelli, Lead Meteorologist
          Region III (3AM12)


      Because the issues are primarily of a policy nature, your
request for Model Clearinghouse review of procedures relating to
redesignation of the Warren County, New Jersey nonattainment area
(NAA) to attainment was referred to the SO2/Particulate Matter
Programs Branch for resolution.  Their attached memorandum
addressing the issues represents the Model Clearinghouse
position. 

     Our reading of the memorandum is that any modeling analysis
done for the Martins Creek power plant must include receptors at
any point where the highest concentrations occur and at any point
where violations of the NAAQS are possible.  This would logically
include receptors both within and outside of the NAA.  The
memorandum goes on to say that if an acceptable modeling analysis
at existing SIP limits does not show violations of the NAAQS in
the NAA, the redesignation could proceed before the State
completes the necessary effort to resolve the violations outside
of the area.  

     If you have any further questions please contact Doug Grano
at FTS 629-5255.
