              A.   APPLICABILITY

                   1.   This  procedure  may be used to provide substitute
                        data for affected  sources that meet the specified
                        conditions in Chapter  2, Subdivision E, Paragraph
                        1,   Subparagraph   b,  Clause   i,   Chapter   2,
                        Subdivision E, Paragraph 2, Subparagraph b, Clause
                        i,  and  Chapter 3, Subdivision  I,  Paragraph  2,
                        Subparagraph a.

              B.   PROCEDURE

                   1.   Where  N  is   the  number  of  hours  of  missing
                        emissions data,  determine  the  substitute hourly
                        NOx  concentration (in ppmv), or the  hourly  flow
                        rate  (in  scfh)  by  averaging  the  measured  or
                        substituted  values  for  the 1N hours immediately
                        before the missing data period  and  the  1N hours
                        immediately after the missing data period.

                   2.   Where  1N  hours before or after the missing  data
                        period  includes   a   missing   data   hour,  the
                        substituted  value  previously  recorded for  such
                        hour(s)  pursuant  to  the missing data  procedure
                        shall  be  used  to  determine   the   average  in
                        accordance with Subdivision B, Paragraph 1 above.

                   3.   Substitute the calculated average value  for  each
                        hour of the N hours of missing data.

              A.   PROCEDURE

                   Test  the  relative  accuracy  test  data  sets and the
                   relative   accuracy   test  audit  data  sets  for  NOx
                   pollutant  concentration   monitors,  fuel  gas  sulfur
                   content  monitors,  flow monitors,  and  emission  rate
                   measurement  systems  using   the  procedures  outlined
                   below.

                   1.   Calculate  the  mean  of  the   difference   using
                        Equation  2-1  of  40  CFR,  Part  60, Appendix B,
                        Performance  Specification  2.  To calculate  bias
                        for  an NOx pollutant concentration  monitor,  "d"
                        shall,   for   each  paired  data  point,  be  the
                        difference between  the  NOx  concentration values
                        (in  ppm) obtained from the reference  method  and
                        the  monitor.    To  calculate  bias  for  a  flow
                        monitor, "d" shall, for each paired data point, be
                        the difference between  the  flow  rate values (in
                        dscfh) obtained from the reference method  and the
                        monitor.   To calculate bias for an emission  rate
                        measurement  system,  "d"  shall,  for each paired
                        data point, be the difference between the emission
                        rate values (in lb/hr) obtained from the reference
                        method and the monitoring system.

                   2.   Calculate the standard deviation,  Sd, of the data
                        set  using  Equation  2-2  of  40  CFR,  Part  60,
                        Appendix B, Performance Specification 2.

                   3.   Calculate the confidence coefficient, cc,  of  the
                        data  set  using  Equation 2-3 of 40 CFR, Part 60,
                        Appendix B, Performance Specification 2.

                   4.   The monitor passes  the  bias  test  if  it  meets
                        either of the following criteria:

                        a.   the absolute value of the mean difference  is
                             less than |cc|.

                        b.   the  absolute value of the mean difference is
                             less than 1 ppmv.

              A.   Quality Control Program

                   Develop and implement a quality control program for the
                   continuous  emission   monitoring   systems  and  their
                   components.   As  a  minimum, include in  each  quality
                   control program a written plan that describes in detail
                   complete, step-by-step  procedures  and  operations for
                   each of the following activities:

                   1.   Calibration Error Test Procedures

                        Identify   calibration   error   test   procedures
                        specific  to  the  CEMS  that may require variance
                        from the procedures used during certification (for
                        example,  how  the  gases  are   to  be  injected,
                        adjustments   of   flow   rates   and   pressures,
                        introduction of reference values, length  of  time
                        for  injection  of  calibration  gases,  steps for
                        obtaining  calibration  error,  determination   of
                        interferences,  and  when  calibration adjustments
                        should be made).

                   2.   Calibration and Linearity Adjustments

                        Explain how each component of  the  CEMS  will  be
                        adjusted   to   provide   correct   responses   to
                        calibration   gases,   reference   values,  and/or
                        indications  of  interference  both initially  and
                        after  repairs  or  corrective  action.   Identify
                        equations,  conversion  factors, assumed  moisture
                        content, and other factors  affecting  calibration
                        of each CEMS.

                   3.   Preventative Maintenance

                        Keep a written record of procedures, necessary  to
                        maintain  the  CEMS  in proper operating condition
                        and a schedule for those procedures.







                   4.   Audit Procedures

                        Keep  copies  of  written  reports  received  from
                        testing  firms/laboratories   of   procedures  and
                        details specific to the installed CEMS  that  were
                        to  be  used by the testing firms/laboratories for
                        relative  accuracy  test  audits, such as sampling
                        and     analysis     methods.      The     testing
                        firms/laboratories  shall  have received  approval
                        from the District by going through  the District's
                        laboratory approval program.

                   5.   Record Keeping Procedures

                        Keep  a written record describing procedures  that
                        will be  used  to implement the record keeping and
                        reporting requirements.

                   Specific provisions of Section A-3 and A-5 above of the
                   quality  control  programs  shall  constitute  specific
                   guidelines for facility  personnel.  However facilities
                   shall be required to take  reasonable  steps to monitor
                   and assure implementation of such specific  guidelines.
                   Such  reasonable  steps  may  include  periodic audits,
                   issuance  of periodic reminders, implementing  training
                   classes, discipline  of  employees  as  necessary,  and
                   other  appropriate  measures.   Steps  that  a facility
                   commits to take to monitor and assure implementation of
                   the  specific  guidelines  shall  be  set forth in  the
                   written plan and shall be the only elements  of Section
                   A-3  and  A-5  that constitute enforceable requirements
                   under the written plan, unless other program provisions
                   are  independently   enforceable   pursuant   to  other
                   requirements  of  the  NOx  protocols  or  District  or
                   federal rules or regulations.

              B.   FREQUENCY OF TESTING

                   The frequency at which each quality assurance test must
                   be performed is as follows:

                   1.   Daily Assessments

                        For  each  monitor  or CEMS, perform the following
                        assessments  on each day  during  which  the  unit
                        combusts  any  fuel   or  processes  any  material
                        (hereafter referred to as a "unit operating day"),
                        or for a monitor or a CEMS on a bypass stack/duct,
                        on each day during which  emissions  pass  through
                        the bypass stack or duct.  These requirements
                        are  effective as of the date when the monitor  or
                        CEMS completes certification testing.

                        a.   Calibration Error Testing Requirements for
                             Pollutant Concentration Monitors and O2
                             Monitors

                             Test,  record,  and  compute  the calibration
                             error  of  each  NOx  pollutant concentration
                             monitor and O2 monitor  at least once on each
                             unit  operating  day,  or  for   monitors  or
                             monitoring systems on bypass stacks/ducts  on
                             each  day  that  emissions  pass  through the
                             bypass  stack  or  duct.  Conduct calibration
                             error  checks,  to  the  extent  practicable,
                             approximately 24 hours  apart.   Perform  the
                             daily calibration error test according to the
                             procedure  in  Paragraph  B.1.a.ii.  of  this
                             Attachment.

                             For  units  with  more  than  one span range,
                             perform the daily calibration error  test  on
                             each  scale that has been used since the last
                             calibration  error test.  For example, if the
                             emissions concentration  has not exceeded the
                             low-scale  span  range  since   the  previous
                             calendar day, the calibration error  test may
                             be  performed  on  the  low-scale  only.  If,
                             however,  the  emissions  concentration   has
                             exceeded  the  low-scale span range since the
                             previous calibration  error test, perform the
                             calibration error test  on  both the low- and
                             high-scales

                             i.   Design   Requirements  for   Calibration
                                  Error  Testing   of   NOx  Concentration
                                  Monitors and O2 Monitors

                                  Design and equip each NOx  concentration
                                  monitor   and   O2   monitor   with    a
                                  calibration   gas  injection  port  that
                                  allows a check of the entire measurement
                                  system   when  calibration   gases   are
                                  introduced.  For extractive and dilution
                                  type monitors, all monitoring components
                                  exposed to the sample gas, (for example,
                                  sample   lines,    filters,   scrubbers,
                                  conditioners, and as  much  of the probe
                                  as   practical)  are  included  in   the
                                  measurement  system.   For  in situ type
                                  monitors,  the  calibration  must  check
                                  against   the   injected   gas  for  the
                                  performance   of   all  electronic   and
                                  optical    components   (for    example,
                                  transmitter, receiver, analyzer).

                                  Design   and   equip    each   pollutant
                                  concentration monitor and  O2 monitor to
                                  allow     daily     determinations    of
                                  calibration error (positive or negative)
                                  at the zero-level (0  to  20  percent of
                                  each span range) and high-level  (80  to
                                  100   percent   of   each   span  range)
                                  concentrations.

                             ii.  Calibration    Error    Test   for   NOx
                                  Concentration Monitors and O2 Monitors

                                  Measure  the calibration error  of  each
                                  NOx  concentration   analyzer   and   O2
                                  monitor  once  each day according to the
                                  following procedures:

                                  If any manual or  automatic  adjustments
                                  to   the   monitor  settings  are  made,
                                  conduct the  calibration error test in a
                                  way   that   the   magnitude    of   the
                                  adjustments   can   be   determined  and
                                  recorded.

                                  Perform calibration error  tests  at two
                                  concentrations:  (1) zero-level and  (2)
                                  high  level.  Zero  level  is  0  to  20
                                  percent  of  each  span  range, and high
                                  level is 80 to 100 percent  of each span
                                  range.    Use   only   NIST/EPA-approved
                                  certified  reference material,  standard
                                  reference  material,   or   Protocol   1
                                  calibration   gases   certified  by  the
                                  vendor  to  be within 2 percent  of  the
                                  label value.

                                  Introduce the calibration gas at the gas
                                  injection  port   as   specified  above.
                                  Operate  each  monitor  in   its  normal
                                  sampling   mode.   For  extractive   and
                                  dilution type  monitors,  pass the audit
                                  gas   through  all  filters,  scrubbers,
                                  conditioners,    and    other    monitor
                                  components  used  during normal sampling
                                  and  through  as much  of  the  sampling
                                  probe as practical.   For  in  situ type
                                  monitors,  perform  calibration checking
                                  all   active  electronic   and   optical
                                  components,  including  the transmitter,
                                  receiver, and analyzer.   Challenge  the
                                  NOx  concentration  monitors  and the O2
                                  monitors once with each gas.  Record the
                                  monitor    response    from   the   data
                                  acquisition  and handling  system.   Use
                                  the following  equation to determine the
                                  calibration error  at each concentration
                                  once each day:

                                  CE  =  |R-A|  x  100     (Eq. C-1)

                                                   S

                             Where,

                                  CE  = The percentage  calibration  error
                                       based on the span range

                                  R = The  reference  value  of  zero-  or
                                       high-level      calibration     gas
                                       introduced   into  the   monitoring
                                       system.

                                  A   =   The  actual  monitoring   system
                                       response to the calibration gas.

                                  S = The span range of the instrument

                             b.   Calibration  Error  Testing Requirements
                                  for Flow Monitors

                                  Test,    compute,    and   record    the
                                  calibration error of each  flow  monitor
                                  at  least once each unit operating  day,
                                  or for monitors or monitoring systems on
                                  bypass  stacks/ducts,  on  each day that
                                  emissions pass the bypass stack or duct.
                                  Introduce  the reference values  to  the
                                  probe tip (or   equivalent)  or  to  the
                                  transducer.   The  reference values must
                                  have at least two reference  values: (1)
                                  zero to 20 percent of span range  or  an
                                  equivalent reference value (for example,
                                  pressure pulse or electronic signal),and
                                  (2) 50 to 70 percent of span range or an
                                  equivalent reference value.  Record flow
                                  monitor output from the data acquisition
                                  and  handling  systems  before and after
                                  any    adjustments.     Calculate    the
                                  calibration  error  using the  following
                                  equation:

                                  CE  =  |R-A|  x  100     (Eq. C-2)

                                                 S

                             Where

                                  CE = Percentage calibration  error based
                                       on the span range

                                  R  =  Reference value of zero- or  high-
                                       level  calibration  gas  introduced
                                       into the monitoring system.

                                  A = Actual monitoring system response to
                                       the calibration gas.

                                  S = Span range of the flow monitor.

                        c.   Interference Check

                             Perform  the  daily flow monitor interference
                             checks specified  in  Paragraph  B.1.c.i.  of
                             this  Attachment  at least once per operating
                             day (when the unit(s) operate for any part of
                             the day).

                             i.   Design  Requirements  for  Flow  Monitor
                                  Interference Checks

                                  Design and  equip each flow monitor with
                                  a  means  to ensure  that  the  moisture
                                  expected  to  occur  at  the  monitoring
                                  location does  not  interfere  with  the
                                  proper    functioning    of   the   flow
                                  monitoring  system.   Design  and  equip
                                  each  flow  monitor  with   a  means  to
                                  detect,  on  at  least  a  daily  basis,
                                  pluggage of each sample line and sensing
                                  port, and malfunction of each resistance
                                  temperature detector (RTD), transceiver,
                                  or equivalent.

                                  Design   and   equip  each  differential
                                  pressure flow monitor  to provide (1) an
                                  automatic,      periodic     backpurging
                                  (simultaneously on  both  sides  of  the
                                  probe)    or    equivalent   method   of
                                  sufficient force  and  frequency to keep
                                  the probe and lines sufficiently free of
                                  obstructions on at least  a  daily basis
                                  to prevent sensing interference, and (2)
                                  a means to detecting leaks in the system
                                  at least on a quarterly basis  (a manual
                                  check is acceptable).

                                  Design   and  equip  each  thermal  flow
                                  monitor with  a  means  to  ensure on at
                                  least  a  daily  basis  that  the  probe
                                  remains  sufficiently  clean  to prevent
                                  velocity sensing interference.

                                  Design  and  equip each ultrasonic  flow
                                  monitor with a  means  to  ensure  on at
                                  least    a    daily   basis   that   the
                                  transceivers remain  sufficiently  clean
                                  (for example, backpurging the system) to
                                  prevent velocity sensing interference.

                        d.   Recalibration

                             Adjust   the   calibration,   at  a  minimum,
                             whenever the daily calibration  error exceeds
                             the  limits  of  the  applicable  performance
                             specification   for   the  NOx  monitor,   O2
                             monitor,   or  flow  monitor.    Repeat   the
                             calibration  error  test  procedure following
                             the adjustment or repair to  demonstrate that
                             the   corrective   actions   were  effective.
                             Document the adjustments made.

                        e.   Out-of-Control Period

                             An  out-of-control  period  occurs  when  the
                             calibration  drift  of  an  NOx concentration
                             monitor  exceeds 5.0 percent based  upon  the
                             span range  value, when the calibration drift
                             of an O2 monitor  exceeds  1.0 percent O2, or
                             when the calibration drift of  a flow monitor
                             exceeds 6.0 percent based upon the span range
                             value,   which   is   twice   the  applicable
                             specification.   The  out-of-control   period
                             begins  with  the  hour  of completion of the
                             failed calibration drift test  and  ends with
                             the hour of completion following an effective
                             recalibration.      Whenever    the    failed
                             calibration, corrective action, and effective
                             recalibration occur within the same hour, the
                             hour is not out-of-control if 2 or more valid
                             readings are obtained  during  that  hour  as
                             required   by   Chapter   2,  Subdivision  B,
                             Paragraph 5.

                             An out-of-control period also occurs whenever
                             interference of a flow monitor is identified.
                             The  out-of-control  period begins  with  the
                             hour  of  the failed interference  check  and
                             ends  with  the  hour  of  completion  of  an
                             interference check that is passed.

                        f.   Data Recording

                             Record  and tabulate  all  calibration  error
                             test data according to the month, day, clock-
                             hour,  and   magnitude  in  ppm,  DSCFH,  and
                             percent  volume.    Program   monitors   that
                             automatically  adjust data  to the calibrated
                             corrected calibration  values  (for  example,
                             microprocessor control) to record either: (1)
                             the  unadjusted  concentration  or  flow rate
                             measured in the calibration error test  prior
                             to  resetting  the  calibration,  or  (2) the
                             magnitude  of  any  adjustment.   Record  the
                             following     applicable     flow     monitor
                             interference    check    data:   (1)   sample
                             line/sensing   port   pluggage,    and    (2)
                             malfunction  of  each  RTD,  transceiver,  or
                             equivalent.

                   2.   Semiannual Assessments

                        For  each  monitor  or CEMS, perform the following
                        assessments once semiannually  after  the calendar
                        operating   quarter   in  which  the  monitor   or
                        monitoring system was last  tested,  as  specified
                        below  for the type of test.  For the monitors  or
                        CEMS on  bypass  stacks/ducts, the assessments are
                        to be performed once  every  two successive bypass
                        operating quarters after the calendar  quarter  in
                        which  the  monitor  or monitoring system was last
                        tested, as specified below  for  the type of test.
                        This requirement is effective as of  the  calendar
                        operating  quarter  or  bypass  operating  quarter
                        following   the  calendar  quarter  in  which  the
                        monitor or CEMS is certified.

                        Relative accuracy  tests  may  be  performed on an
                        annual basis rather than on a semiannual  basis if
                        the  relative  accuracy  during the previous audit
                        for the NOx pollutant concentration  monitor, flow
                        monitoring   system,   and   NOx   emission   rate
                        measurement system is 7.5 percent or less.

                        For monitors on any stack or duct through which no
                        emissions  have  passed  in two or more successive
                        quarters,  the  semiannual  assessments   must  be
                        performed within 14 operating days after emissions
                        pass through the stack/duct.

                        a.   Relative Accuracy Test Audit

                             Perform  relative  accuracy  test audits  and
                             bias tests semiannually and no  less  than  4
                             months   apart   for   each   NOx   pollutant
                             concentration  monitor,  stack gas volumetric
                             flow  measurement  systems,   and   the   NOx
                             emission    rate    measurement   system   in
                             accordance  with Chapter  2,  Subdivision  B,
                             Paragraph  10,   Chapter  2,  Subdivision  B,
                             Paragraph 11, and  Chapter  2, Subdivision B,
                             Paragraph   12.    For  monitors  on   bypass
                             stacks/ducts, perform  relative accuracy test
                             audits  once  every  two  successive   bypass
                             operating   quarters   in   accordance   with
                             Paragraphs 2.B.10, 2.B.11, and 2.B.12 .

                        b.   Out-of-Control Period

                             An out-of-control period occurs under any  of
                             the  following  conditions:  (1) The relative
                             accuracy  of  an  NOx pollutant concentration
                             monitor or the NOx  emission rate measurement
                             system  exceeds  20.0  percent;  or  (2)  the
                             relative accuracy of the  flow  rate  monitor
                             exceeds  10.0  percent.   The  out-of-control
                             period begins with the  hour of completion of
                             the failed relative accuracy test  audit  and
                             ends   with  the  hour  of  completion  of  a
                             satisfactory relative accuracy test audit.

                             Failure  of  the  bias  test  results  in the
                             system or monitor being out-of-control.   The
                             out-of-control  period  begins with the  hour
                             of completion of the failed  bias  test audit
                             and  ends  with the hour of completion  of  a
                             satisfactory bias test.

                              EQUIPMENT TUNING PROCEDURES


              A.   PROCEDURES

                   Nothing in this Equipment  Tuning  Procedure  shall  be
                   construed  to  require  any  act or omission that would
                   result in unsafe conditions or would be in violation of
                   any regulation or requirement  established  by  Factory
                   Mutual,   Industrial   Risk   Insurers,  National  Fire
                   Prevention  Association, the California  Department  of
                   Industrial Relations  (Occupational  Safety  and Health
                   Division),  the Federal Occupational Safety and  Health
                   Administration,   or  other  relevant  regulations  and
                   requirements.

              1.   Operate the unit at  the  firing  rate  most typical of
                   normal operation.  If the unit experiences  significant
                   load variations during normal operation, operate  it at
                   its average firing rate.

              2.   At  this  firing  rate,  record  stack-gas temperature,
                   oxygen concentration, and CO concentration (for gaseous
                   fuels) or smoke-spot number 2 (for  liquid  fuels), and
                   observe   flame   conditions   after   unit   operation
                   stabilizes at the firing rate selected.  If the  excess
                   oxygen  in  the  stack  gas  is at the lower end of the
                   range of typical minimum values,  and  if  CO emissions
                   are  low  and  there  is no smoke, the unit is probably
                   operating at near optimum efficiency at this particular
                   firing rate.

              3.   Increase  combustion air  flow  to  the  furnace  until
                   stack-gas oxygen  levels increase by one to two percent
                   over the level measured  in  Step  2.   As  in  Step 2,
                   record the stack-gas temperature, CO concentration (for
                   gaseous fuels) or smoke-spot number (for liquid fuels),
                   and  observe  flame  conditions for these higher oxygen
                   levels after boiler operation stabilizes.

              4.   Decrease combustion air flow until the stack gas oxygen
                   concentration is at the  level measure in Step 2.  From
                   this level, gradually reduce the combustion air flow in
                   small increments.  After each  increments,  record  the
                   stack-gas   temperature,   oxygen   concentration,   CO
                   concentration   (for  gaseous  fuels),  and  smoke-spot
                   number (for liquid  fuels).  Also observe the flame and
                   record any changes in its condition.

              5.   Continue to reduce combustion  air flow stepwise, until
                   one of these limits is reached:

                   a.   Unacceptable  flame  conditions,   such  as  flame
                        impingement  on  furnace  walls  or burner  parts,
                        excessive  flame carryover, or flame  instability;
                        or

                   b.   Stack gas CO  concentrations greater than 400 ppm;
                        or

                   c.   Smoking at the stack; or

                   d.   Equipment-related   limitations,   such   as   low
                        windbox/furnace  pressure  differential,  built in
                        air-flow limits, etc.

              6.   Develop  an O2/CO curve (for gaseous fuels) or O2/smoke
                   curve (for liquid fuels) using the excess oxygen and CO
                   or smoke-spot  number  data obtained at each combustion
                   air flow setting.

              7.   From the curves prepared  in Step 6, find the stack-gas
                   oxygen  levels  where the CO  emissions  or  smoke-spot
                   number equal the following values:

                        Fuel             Measurement           Value

                        Gaseous          CO emissions          400 ppm

                        #1 and #2 oils   smoke-spot number     number 1

                        #4 oil           smoke-spot number     number 2

                        #5 oil           smoke-spot number     number 3

                        Other oils       smoke-spot number     number 4

                   The above conditions are referred to as the CO or smoke
                   thresholds, or as the minimum excess oxygen level.

                   Compare this minimum  value  of  excess  oxygen  to the
                   expected   value   provided   by  the  combustion  unit
                   manufacturer.    If   the   minimum  level   found   is
                   substantially higher than the  value  provided  by  the
                   combustion  unit  manufacturer,  burner adjustments can
                   probably  be  made  to  improve  fuel and  air  mixing,
                   thereby allowing operation with less air.

              8.   Add  0.5  to 2.0 percent of the minimum  excess  oxygen
                   level found  in  Step  7  and  reset burner controls to
                   operate automatically at this higher  stack-gas  oxygen
                   level.   This  margin  above  the  minimum oxygen level
                   accounts for fuel variations, variations in atmospheric
                   conditions, load changes, and nonrepeatability  or play
                   in automatic controls.

              9.   If the load of the combustion unit varies significantly
                   during  normal  operation,  repeat Steps 1-8 for firing
                   rates that represent the upper  and lower limits of the
                   range of the load.  Because control  adjustments at one
                   firing  rate  may  affect  conditions  at other  firing
                   rates, it may not be possible to establish  the optimum
                   excess  oxygen level at all firing rates.  If  this  is
                   the case,  choose the burner control settings that give
                   best performance  over  the  range of firing rates.  If
                   one firing rate predominates,  settings should optimize
                   conditions at that rate.

              10.  Verify that the new settings can accommodate the sudden
                   load changes that may occur in daily  operation without
                   adverse effects.  Do this by increasing  and decreasing
                   load rapidly while observing the flame and  stack.   If
                   any  of  the  conditions  in  Step  5 result, reset the
                   combustion controls to provide a slightly  higher level
                   of  excess oxygen at the affected firing rates.   Next,
                   verify  these  new  recorded  at  steady-rate operating
                   conditions for future reference.

             (1)  AFTERBURNERS,  also  called VAPOR INCINERATORS,  are  air
                 pollution control devices in which combustion converts the
                 combustible  materials  in  gaseous  effluents  to  carbon
                 dioxide and water.

                 reporting program.

             (3)  BOILER  should  generally be considered as any combustion
                 equipment  used  to  produce  steam,  including  a  carbon
                 monoxide boiler.   This  would  generally  not  include  a
                 process  heater  that transfers heat from combustion gases
                 to process streams,  a  waste heat recovery boiler that is
                 used to recover sensible  heat from the exhaust of process
                 equipment  such as a combustion  turbine,  or  a  recovery
                 furnace  that   is  used  to  recover  process  chemicals.
                 Boilers used primarily  for residential space and/or water
                 heating are not affected by this section.

             (4)  BREAKDOWN  means  a  condition  caused  by  circumstances
                 beyond the operator's control  which  result  in a fire or
                 mechanical  or  electrical  failure  causing  an  emission
                 increase  in  excess  of  emissions under normal operating
                 conditions.

             (5)  BURN  means  to combust any  gaseous  fuel,  whether  for
                 useful heat or  by  incineration  without recovery, except
                 for flaring or emergency vent gases.

             (6)  BYPASS OPERATING QUARTER means each calendar quarter that
                 emissions pass through the bypass stack or duct.

             (7)  CALCINER is a rotary kiln where calcination  reaction  is
                 carried out between 1315 oC to 1480 oC.

             (8)  CEMENT  KILN is a device for the calcining and clinkering

                 dust in the dry-process manufacture of  cement.

             (9)  CONCENTRATION  LIMIT is a value  expressed  in  ppmv,  is
                 measured over any continuous 60 minutes, is elected by the
                 Facility Permit holder  for  a  large  NOx  source, and is
                 specified in the Facility Permit.

             (10) CONTINUOUS  EMISSIONS  MONITORING  SYSTEM (CEMS)  is  the
                 total   equipment   required  for  the  determination   of
                 concentrations of air  contaminants and diluent gases in a
                 source effluent as well as mass emission rate.  The system
                 consists of the following three major subsystems:

                  (A)  SAMPLING INTERFACE is that portion of the monitoring
                       system that performs  one  or  more of the following

                       separation,  transportation, and conditioning  of  a
                       sample of the  source  effluent or protection of the
                       analyzer from the hostile  aspects  of the sample or
                       source environment.

                            gas  as  applicable,  and  generates  a  signal
                            output which  is  a function of a concentration
                            of that diluent gas.

                  (C)  DATA  RECORDER  is that portion  of  the  monitoring
                       system  that provides  a  permanent  record  of  the
                       output signals  in terms of concentration units, and
                       includes additional  equipment  such  as  a computer
                       required  to convert the original recorded value  to
                       any value required for reporting.

             (11) CONTINUOUS  PROCESS   MONITORING   SYSTEM  is  the  total
                  equipment required for the measurement  and collection of
                  process variables (e.g., fuel usage rate,  oxygen content
                  of stack gas, or process weight).  Such CPMS  data  shall
                  be used in conjunction with the appropriate emission rate
                  to determine NOx emissions.

             (12) CONTINUOUSLY MEASURE means to measure at least once every
                  15  minutes  except  during period of routine maintenance

                  measurement and transmission.

             (17) EMERGENCY EQUIPMENT is equipment solely used on a standby
                  basis  in  cases  of  emergency,  defined   as  emergency
                  equipment  on  the Facility Permit; or is equipment  that
                  does not operate  more than 200 hours per year and is not
                  used in conjunction  with  any voluntary demand reduction
                  program,  and is defined as emergency  equipment  in  the
                  Facility Permit.

             (18) EMISSION FACTOR  is the value specified in Tables 1 (NOx)

                  for NOx and SOx.

             (19) EMISSION RATE (ER) - is a value expressed in terms of NOx
                  mass emissions per unit  of heat input, and derived using
                  the   methodology  specified   in   the   "Protocol   for
                  Monitoring,  Reporting,  and  Recordkeeping for Oxides of
                  Nitrogen (NOx) Emissions" Chapter .

             (20) EXISTING EQUIPMENT is any equipment which can emit NOx at
