KERAPCD RULE 108.1 SOURCE SAMPLING
LAST REVISED 05/06/91


RULE 108.1 Source Sampling - Adopted 1972-75, Renumbered 5/89,
Revised 5/6/91

I.    Sampling Facilities

      Upon the request of the Control Officer and as directed by
      him, the owner of any source operation which emits or may
      emit air contaminants, for which emission limits have been
      established, shall provide the following facilities,
      constructed in accordance with the general industry safety
      orders of the State of California:

      a) Sampling ports,
      b) Sampling platforms,
      c) Access to sampling platforms, and
      d) Utilities for sampling equipment

      Sampling port locations must be determined according to
      criteria in the California Air Resources Board Monitoring
      Quality Assurance Volume VI, Standard Operating Procedures
      for Stationary Emission Monitoring and Testing.

II.   Collection of Samples

      The owner of such a source operation, when requested by
      the Control Officer, shall provide records or other
      information which will enable the Control Officer to
      determine when a representative sample can be taken.

      In addition, upon the request of the Control Officer and
      as directed by him, the owner of such a source operation
      shall collect, have collected, or allow the Control
      Officer to collect, a source sample.

III.  Test Methods

      The applicable test method, if not specified in the rule,
      shall be conducted in accordance with Title 40 CFR,
      Subpart 60, Appendix A - Reference Methods, except
      particulate matter (PM10) for compliance with Rule 210.1
      requirements shall be conducted in accordance with
      Title 40 CFR, Subpart 51, Appendix M, Method 201 or 201A. 
      Where no test method exists in the preceding references
      for a source type source sampling shall be conducted in
      accordance with California Air Resources Board (CARB)
      approved methods.

IV.   Test Procedures

      For the purpose of determining compliance with an
      applicable standard or numerical limitation, the
      arithmetic mean of three test runs shall apply, unless two
      of the three results are above the applicable limit.  If
      two of three runs are above an applicable limit the test
      cannot be used to demonstrate compliance with an
      applicable limit.

      A scheduled source test may not be discontinued solely due
      to the failure of one or more runs failing to meet
      applicable standards.

      In the event that a sample is accidentally lost or
      conditions occur in which one of the three runs must be
      discontinued because of forced shutdown, failure of an
      irreplaceable portion of the sampling train, extreme
      meteorological conditions presenting a hazard to the
      sampling team, or other circumstances beyond the owner or
      operator's control, upon the Control Officer's approval,
      compliance may be determined using the arithmetic mean of
      the other two runs.

V.    Administrative Requirements

      District must be notified 30 days prior to any compliance
      source testing and the owner shall submit a source test
      plan for District approval 15 days prior to source
      sampling.

      Source sampling to determine the compliance status of an
      emissions source shall be witnessed or authorized by
      District personnel.

      Source test reports must be submitted to the District
      within 60 days of completion of field testing.  Source
      tests must be submitted for all District-authorized
      compliance source tests regardless of pass, fail or
      reschedule because of failure, status.  A District-authorized compliance source test shall not be
      discontinued solely due to the failure of one or more runs
      failing to meet applicable standards.
