Simultaneous inlet/outlet testing must only be performed on the last control device prior to
exhausting to the atmosphere through the stack. Where units have controls that handle only a portion of
the exhaust gas stream (e.g., for reheat purposes), the control handling the majority of the gas stream
should be tested.
4. At what date is the test to be completed? How soon can it take place?
A. A site-specific test plan and a Quality Assurance Program Plan (QAPP) must be developed for
each unit to be tested. Information on the preparation of the site-specific test plan may be
found in the EPA document entitled "Preparation
and Review of Site-specific Test Plans". Requirements
for the QAPP may be found in the EPA document entitled "EPA Requirements for Quality Assurance
Project Plans for Environmental Data Operations; EPA QA/R-5". Further guidance on the
preparation of QAPPs may be found in the document entitled "EPA Guidance for Quality Assurance
Project Plans; EPA QA/G-5". Both the site-specific test plan and QAPP for each unit to be
tested should be submitted by June l, 1999 to:
Mr. William Grimley/Ms. Lara Autry
Emission Measurement Center (MD-l9)
U.S. Environmental Protection Agency
Research Triangle Park, North Carolina 27711
Attn: Electric Utility Steam Generating Unit Mercury Test Program
The EPA will review and approve the site-specific test plan and QAPP, or provide comments for
revision if necessary, within 30 days of receipt. The site-specific test plan must include
proposed test dates. The testing should not begin until EPA has approved the test plan and
QAPP, so please plan for EPA's 30-day review period in scheduling test dates. The EPA would
prefer to have test data submitted as soon as it is convenient for owners/operators to do so,
but in any event owners/operators should complete all testing such that all final emission test
reports are received at the above address within 90 days of completion of testing but no later
than May 31, 2000.
