RULE 202.1 Experimental Research Operations - Adopted 12/15/80
          Renumbered 5/89

          The Control Officer may exempt from experimental research
          operations requirements of Regulation II if the following
          requirements are met.  Failure to satisfy any of these
          requirements will result in revocation of an exemption and
          require compliance with requirements of Regulation II.

          A.  The purpose of the operation is to permit investigation,
              experimentation or research to advance the state of knowledge
              or the state of art of a particular control technology or
              industrial process;

          B.  The Control Officer is notified, in writing, of the purpose,
              goals and objectives of the project, measures to be taken to
              minimize the emission of air contaminants, the proposed
              installation date, the planned startup date, the expected
              duration of the test and test schedules.

          C.  The cumulative total days operation will not exceed 180.  If
              the applicant intends to continue operation of the technology
              or process for more than 180 days, a compliance schedule for
              obtaining necessary permits under Regulation II shall be
              established by the Control Officer.

          D.  Official test results (if the project involves air pollution
              control devices) are submitted to the District, in writing
              and in final form, no more than sixty (60) days after each
              test sequence is complete; and

          E.  The Control Officer has granted prior written approval.

          For purposes of this Rule, "experimental research operations"
          include any air pollution control device or technology or any
          industrial process or technology which is: a) innovative, b) not
          in common use for a particular process, or c) not readily
          available from a commercial supplier.
