             This document provides the technical specifications for
             normally operated RECLAIM sources subject to District Rule
             2011 "Requirements for Monitoring, Reporting, and
             Recordkeeping for Oxides of Sulfur (SOx) Emissions".
             District Rule 2011 divides sources into three categories -
             major sources, SOx process units and Rule 219 - "Equipment
             Not Requiring a Written Permit Pursuant to Regulation II"
             sources.  The one difference in requirements between these
             source categories is the monitoring approach.  A major
             source shall be monitored by a continuous emissions
             monitoring system (CEMS) or alternative monitoring system,
             while a SOx process unit has the option to be monitored
             manually based on fuel usage and emission factor.
             Oxides of sulfur (SOx) emissions shall be composed of sulfur
             dioxide (SO2) emissions.  No later than June 30, 1994 the
             Executive Officer will determine the feasibility for
             estimating sulfur trioxide (SO3) emissions as a function of
             SO2 emissions for a petroleum refinery fluid catalytic
             cracking unit.  If the Executive Officer determines that the
             surrogate approach is feasible then a unit-specific protocol
             will be developed by the Executive Officer by August 31,
             1994.  The Facility Permit holder of a petroleum refinery
             fluid catalytic cracking unit shall apply the protocol
             prospectively to determine SOx emissions on both SO2 and SO3
             emissions.  If the Executive Officer determines that the
             surrogate approach is not feasible then SOx emissions shall
             continue to be based only on SO2 emissions.
             These SOx source categories also differ in the way in which
             they transmit data to the District's Central Station and the
             reporting frequency.  Major sources shall electronically
             transmit the data via an RTU on a daily basis. In addition,
             aggregated SOx emissions from all major sources must be
             submitted in a Monthly Emissions Report.  SOx process units
             have the option to report SOx emissions as part of the
             Quarterly Certification of Emissions required by Rule 2004 -
             The criteria for determining the major source applicability
             is presented in Table 1-A.  A SOx process unit is one or
             more piece(s) of equipment which is not a major source,
             provided that each equipment in a process unit is subject to
             an identical emission factor specified in subdivision (d) of
             Rule 2011.
             The Facility Permit will limit mass emissions in accordance
             with the following relationship:
              ECEMS  +   EEF  +   E219    RTCs
                        ECEMS=   sum  of facility emissions monitored by
                                      CEMS   or   alternative  monitoring

                        EEF     =    sum  of  facility   emissions  from
                                      process units subject  to  emission
                                      factors (EF)pu

                        E219    =    sum   of  facility  emissions  from
                                      equipment  exempt  under  Rule 219,
                                      subject to emission factor (EF)219.

                       RTC       =    RECLAIM Trading Credit held  by the
                                      Facility Permit holder

                  The fuel usage for any process unit or equipment exempt
                  under Rule 219 shall not exceed the value determined in
                  accordance with the following relationship:

                        (FxEF)pu +  (FxEF)219 < RTC -  ECEMS


                       F         =    Fuel usage for the process unit  or
                                      equipment exempt under Rule 219

                  The  Facility Permit holder shall document the duration
                  of operating  time  of  any  rental  equipment  at  the
                  Facility.   Emissions generated by any rental equipment
                  which exceeds  72 hours of operation in a quarter shall
                  be  determined and  reported  by  the  Facility  Permit
                  holder   according   to   the   applicable  methodology
                  specified for each major source or process unit.

                  This document has been divided into chapters addressing
                  the various compliance aspects of Rule 2011.  A summary
                  of each chapter follows:

                  MONITORING SYSTEM (CEMS)

                  Chapter 2 describes the methodologies for measuring and
                  reporting SOx emissions from major sources.  If a major
                  source category is applicable, then the Facility Permit
                  holder shall be required to comply with the performance
                  standards  associated  with  a CEMS  or  an  equivalent
                  monitoring device.

             For major sources, measurement and reporting requirements
             apply to variables used to calculate the SOx emissions as
             well as the variables used to track the operation of basic,
             control, and monitoring equipment.
             Unless specifically exempted by Rule 2011, the Facility
             Permit holder shall measure and record all applicable
             variables as specified in Table 2-A.
             Several important aspects of Chapter 2 include:
                           equations  describing   the  method  used  to
                            calculate SOx emissions,
                           operational requirements,
                           obtaining valid data points,
                           alternative data acquisition methods,
                           accuracy requirements,
                           quality assurance procedures,
                           missing data procedures,
                           final and interim reporting procedures, and


             RULE 219 EQUIPMENT
             Chapter 3 describes the measuring and reporting requirements
             for the SOx process unit category and equipment exempt from
             permit under Rule 219.  SOx process units which comprise of
             one or more pieces of equipment in accordance with Rule 2011
             shall base emission calculations primarily on fuel
             consumption or operating time in conjunction with the
             emission factor.  The requirements and procedures for an
             emission factor and election conditions for an alternative
             emission factor shall apply to process units.  These SOx
             process units may include equipment that are lumped together
             only if the units have the same emission factor.
             Important aspects of Chapters 3 include equations describing
             the method used to calculate SOx emissions and reporting
             procedures for process units as well as determining SOx
             emissions from equipment exempt under Rule 219.


             This Chapter  presents a brief description of the required
             test methods for determining alternative emission factors
             for process units .


             Once the variables for determining emissions and equipment
             operations have been measured, the measured data would be
             stored at the facility.  In addition, selected measured and
             calculated data would be transmitted to the District's
             Central Station Computer.  This storing and transmitting of
             data for major sources shall be performed by the remote
             terminal unit (RTU).
             Chapter 5 specifies tasks and characteristics required of
             the RTU as well as a guide for providing the required
             software/hardware for the RTU.  In addition, this chapter
             serves as a:
                            functional guideline for operating requirements of the
                             RTU, and
                            information     source     concerning     RTU
                             hardware/software procurement, configuration,
                             installation, maintenance, and  compatibility
                             with  the  CEMS  and  the District's  Central

                             rules   to  be  implemented  as  of  [Date  of
                            Any SOx  source  or  process unit elected by
                             the Facility Permit holder  or  required to be
                             monitored   with   a   CEMS,   or   equivalent
                             monitoring device; and
                            Any SOx source or process unit for which SOx
                             emissions  reported pursuant to Rule 301  were
                             equal to or  greater  than  10 tons/yr for any
                             calendar year from 1987 to 1991, inclusive,
                             excluding  any  SOx source or  process  unit
                             which has reduced SOx  emissions  to  below 10
                             tons per year to January 1, 1994.
