PART 1  GENERAL

1.1   Purpose

      The purpose of this Rule is to comply with the California Health
      & Safety Code Part 6, Section 44300 et seq., by establishing
      and implementing a program to inventory air toxics emissions,
      to assess the risk to public health from exposure to these
      emissions,  to notify the public of any known significant health
      risk associated with toxic emissions from any facility, and to
      prepare Risk Reduction Audits and Plans to effect risk
      reductions.


1.2   Applicability 

      The provisions of this Rule shall apply to any facility which
      manufactures, formulates, uses or releases any substances
      listed by the California Air Resources Board pursuant to
      Section 44321 of the California Health and Safety Code, or any
      other substance which reacts to form a substance listed
      pursuant to Section 44321. 


1.3   Exemptions

  1.3.1 Economic Poisons (Pesticides)

        This Rule does not apply to any source where economic
        poisons are employed in their pesticidal use, i.e., exclusively
        agricultural operations, unless that source was subject to
        District permit requirements on or before August 1, 1987. 
        As used in this Section, "pesticidal use" does not include the
        manufacture or formulation of pesticides.

  1.3.2 Landfills

        Any solid waste disposal facility in compliance with Section
        41805.5 of the California Health and Safety Code, is in
        compliance with the emissions inventory requirements of this
        Rule.


  1.3.3 Exempt Facilities

        Any facility, that is not listed on the Appendix E-I or E-II of
        the State Guidelines, and emits less than 10 tons per year of
        criteria pollutants, is not required to prepare an
        emissions inventory or risk assessment.


1.4   Effective Dates

      This Rule has been in effect since November 9, 1988.  The Rule in
      its present form is effective on April 26, 1995.


1.5   References

      The requirements of this Rule arise from the provisions of: 

  1.5.1 California Health and Safety Code, Part 6, Air Toxics "Hot
        Spots" Information And Assessment, Sections 44300 to
        44394. 

  1.5.2 Amendments to Titles 17 and 26, California Code of
        Regulations, Subchapter 7.6, Emissions Inventory Criteria
        and Guidelines, Sections 93300 to 93355 (State
        Guidelines).


PART 2  DEFINITIONS

2.1   Air Release or Release

      Any activity that may cause the issuance of air contaminants,
      including the actual or potential spilling, leaking, pumping,
      pouring, emitting, emptying, discharging, injecting, escaping,
      leaching, dumping, or disposing of a substance into the ambient
      air and that results from the routine operation of a facility
      or that is predictable, including, but not limited to, continuous
      and intermittent releases and predictable process upsets or
      leaks.


2.2   Airborne Toxic Risk Reduction Audit and Plan or Audit and
      Plan

      The Audit and Plan specified in Section 3.6.


2.3   Airborne Toxic Risk Reduction Measure or ATRRM

      Those in-plant changes in production processes or feedstocks
      that reduce or eliminate toxic air emissions subject to this
      Rule. ATRRM's may include:

      (1)   Feedstock modification.
      (2)   Product reformulations.
      (3)   Production system modifications.
      (4)   System enclosure, emissions control, capture, or
            conversion.
      (5)   Operational standards and practices modification.

      Airborne toxic risk reduction measures do not include
      measures that will increase risk from exposure to the
      chemical in another media or that increase the risk to
      workers or consumers.


2.4   Cancer Risk

      The added risk (probability) of cancer that results from
      lifetime continuous exposure.  This risk is given in terms of
      the additional probability that cancer will occur in a person
      remaining at a single location for 70 years.  This risk is
      the risk over and above existing risks from other causes.  For
      example, a risk of one per 100,000 indicates the individual's
      added risk of cancer (due to exposure to this source) is one
      chance in 100,000.


2.5   Degree of Accuracy

      The annual emission rate listed in Appendix A-I of the State
      Guidelines.


2.6   Facility

      Every structure, appurtenance, installation, and improvement on
      land which is associated with a source of air releases or
      potential air releases of a hazardous material.


2.7   Health Risk Assessment

      A detailed comprehensive analysis prepared pursuant to Section
      3.5 to evaluate and predict the dispersion of hazardous
      substances in the environment and the potential for exposure of
      human populations, and to assess and quantify both the individual
      and population wide health risks associated with those levels of
      exposure.


2.8   Inventory Update Summary Form

      An emissions summary form sent from the Air Pollution Control
      Officer to be completed and submitted by facilities prior to
      Plan and Report preparation as specified in Subsection 3.3.2.


2.9   Non-Cancer Risk (Hazard Index)

      The non-cancer risk (hazard index) is an indicator of the
      potential health hazard of a substance with regard to its non-
      cancer effects.  The underlying assumption is that there is a
      threshold for these effects and they will not occur if exposure
      remains below a reference  exposure limit (REL).  RELs
      describe acute and chronic exposure limits, i.e., one hour
      maximum and annual average concentrations.  RELs are
      generally based on the most sensitive adverse health effect
      reported in the medical and toxicological literature. 
      Additionally, RELs are designed to protect the most sensitive
      individuals in the population by the inclusion of margins of
      safety.

      An exposure equal to the REL equates to a hazard index score
      of 1.  A hazard index score of 2 means that the concentration of
      toxics in the air is 2 times more than the exposure level that
      causes adverse health effects.  Substances that cause adverse
      health effects to the same organs are added together to
      determine hazard index scores.  


2.10  Operator

      The person who owns or operates a facility or part of a
      facility.


2.11  Plan

      Either the Emissions Inventory Plan which meets the conditions in
      Section 3.1, or the Risk Reduction Plan which meets the
      conditions of Section 3.6.


2.12  Program Categories

      Category 1 Facilities are those facilities that emitted greater
      than 25 tons per year of criteria pollutants during 1989.

      Category 2 Facilities are those facilities that emitted between
      10 and 25 tons per year of criteria pollutants during 1990.

      Category 3 Facilities are those facilities that emitted less than
      10 tons per year of criteria pollutants during 1991 and are
      listed by either the "SIC code" or the "Description of Class" on
      Appendix E-I of the State Guidelines.  Category 3 facilities
      are further divided into 2 subcategories:

         Unique Facilities are those facilities that are different
          from one another to such an extent that the District cannot
          easily calculate emissions and risks due to these
          facilities being very dissimilar in operations and
          emissions.

          Generic Facilities are those facilities for which the
          District can easily calculate emissions and risks due to
          these facilities being very similar in operations and
          emissions.

      Category 4 Facilities are those new facilities that emit
      greater than 10 tons per year of criteria pollutants, or less
      than 10 tons per year of criteria pollutants and are listed on
      Appendix E-I of the State Guidelines, or modified facilities
      that previously emitted less than 10 tons per year and were not
      listed on Appendix E-I of the State Guidelines, but now emit
      greater than 10 tons per year of criteria pollutants, or are
      now listed on Appendix E-I of the State Guidelines.

      Category 5 Facilities are those facilities that emit less than
      10 tons per year of criteria pollutants and are listed on
      Appendix E-II of the State Guidelines.


2.13  Report

      The Emissions Inventory Report specified in the State and
      District Guidelines.


2.14  Significant Risk or Significant Health Risk

      hazard index scores greater than one.



PART 3  REQUIREMENTS

3.1   Toxic Emissions Inventory Plan

  3.1.1 Plan Preparation

    3.1.1.1   The operator of each new facility shall prepare and
              submit to the Air Pollution Control Officer a
              comprehensive Emissions Inventory Plan in accordance
              with District Guidelines, if:

              1)  the facility emits greater than 10 tons per year of
                  criteria pollutants, or
              2)  the facility emits less than 10 tons per year of
                  criteria pollutants and is on the Appendix E-I list
                  of the State Guidelines.

    3.1.1.2   The operator of each modified facility, that had
              previously emitted less than 10 tons per year of
              criteria pollutants and was not listed on Appendix E-I
              of the State Guidelines, shall prepare and submit to the
              Air Pollution Control Officer a comprehensive
              Emissions Inventory Plan in accordance with District
              Guidelines, if the facility now emits greater than 10
              tons per year of criteria pollutants.


  3.1.2 Plan Submission Deadline

        The operator or owner must submit an Emissions Inventory
        Plan to the Air Pollution Control Officer within 120 days
        from the date of the Air Pollution Control Officer's notice
        to prepare a Plan.


  3.1.3 Plan Approval Criteria
   
        The Air Pollution Control Officer shall disapprove the Plans
        unless the District affirmatively finds that all of the
        following conditions are met:

    3.1.3.1   State Plan Criteria

            The Plan meets the requirements established by the State
            Air Resources Board pursuant to Section 44342 of the
            Health and Safety Code.

    3.1.3.2   Plan Design

            The Plan is designed to produce, from the list compiled
            and maintained pursuant to Section 44321 of the Health and
            Safety Code, a comprehensive characterization of the full
            range of hazardous materials that are released, or that
            may be released, to the surrounding air from the
            facility.  Air release data shall be collected at or
            calculated for the primary locations of actual and
            potential release for each hazardous material.  Data
            shall be collected or calculated for all continuous,
            intermittent, and predictable air releases.

    3.1.3.3   Measurement and Estimation Criteria

            The measurement technologies and estimation methods
            proposed are calculated using state-of-the-art methods. 
            The emissions data are sufficiently accurate to produce
            the best available data for providing a true
            representation of the types and quantities of air
            releases from the facility.

    3.1.3.4   Source Testing

            Source testing or other measurement techniques are to
            be used wherever necessary to verify emission estimates,
            as determined by the Air Pollution Control Officer and
            State Air Resources Board and to the extent
            technologically feasible.  All testing devices shall be
            appropriately located, as determined by the Air Pollution
            Control Officer.

    3.1.3.5   Data Requirements

            Data shall be collected or calculated for the relevant
            exposure rate or rates of each hazardous material,
            according to its characteristic toxicity and for the
            emission rate necessary to ensure a characterization of
            risk associated with exposure to releases of the
            hazardous material that meets the degree of accuracy
            requirements of Subsection 2.5.  Sources of all
            emissions shall be described or displayed.


3.2   Toxic Emission Inventory Report 

  3.2.1 Report Preparation and Submission

        The operator shall implement the Plan and prepare and submit
        a Report to the Air Pollution Control Officer within 180 days
        after receiving plan approval by the Air Pollution Control
        Officer.


  3.2.2 Report Preparation and Submission for E-II Facilities

        Facilities emitting less than 10 tons per year of criteria
        pollutants and listed on Appendix E-II of the State Guidelines,
        shall complete a one-time report preparation using the FAC
        and SUP forms.



3.3   Four Year Inventory Updates

      Emissions inventories developed pursuant to this chapter shall be
      updated at least every four years from the prior inventory year,
      in accordance with procedures specified by the District.  These
      four year updates shall take into consideration modifications
      at the facility, improvements in measurement techniques, and
      advancing knowledge concerning the types and toxicity of
      hazardous materials released or potentially released.  The
      inventory update begins with the submittal of an Emissions
      Inventory Update Summary Form.   The District will review the
      Inventory Update Summary Form and determine whether an
      Emissions Inventory Plan and Report will be required for the
      update year.

  3.3.1 Inventory Update Due Dates

        The updated toxic emissions inventories shall be due within
        180 days from the time the District notifies a facility that an
        updated toxic emissions inventory must be prepared.

  3.3.2 Inventory Update Summary Form

        Upon notification by the District, facilities shall prepare
        information on permitted and non-permitted sources to respond
        to questions included in the Inventory Update Summary Forms
        provided by the District.  Facilities must complete and submit
        the Inventory Update Summary Form within a time-frame
        specified by the District.  

        The District will review the Summary Form and shall
        determine if an Emissions Inventory Plan and Report will be
        required for the update year.

        Facilities shall submit an updated Emissions Inventory Plan
        within 120 days from notification by the District that an
        updated Emissions Inventory Plan is required.

        The Inventory Update Summary Form is designed to allow the
        District to determine whether significant increases in
        activity have occurred at the facility which may result in
        potentially significant increases in health risks such that new
        inventory data is needed.  The District will take into account
        the following criteria to determine whether to require a
        facility to submit an update Plan and Report:

    3.3.2.1   Increases in throughput, fuel usage, process rate
              changes, or emissions;

    3.3.2.2   Changes in types of fuels or substances used at the
              facility;

    3.3.2.3   Determinations that previous source test data are
              inadequate;

    3.3.2.4   Addition of new processes or equipment to the facility
              which cause increases in emissions;

    3.3.2.5   Issuance of new permits or changes in permit
              conditions;

    3.3.2.6   Emissions of any listed substances not previously
              reported, including newly listed substances;

    3.3.2.7   Emissions of listed substances whose potency values have
              increased or whose reference exposure levels have
              decreased;

    3.3.2.8   Facility status as it pertains to current or future
              air pollution control measures;

    3.3.2.9   Changes in emissions factors.


3.4   Industry Wide Emissions Inventory

      The Air Pollution Control Officer may prepare an industry
      wide emissions inventory and health risk assessment for
      facilities specified in Section 1.2, to comply with these
      requirements for any class of facilities that the Air Pollution
      Control Officer finds and determines meets all of the following
      conditions:

  3.4.1 All facilities in the class fall within one four-digit
        Standard Industrial Classification Code.

  3.4.2 Individual compliance with this part would impose severe
        economic hardships on the majority of the facilities within the
        class.

  3.4.3 The majority of the class is composed of small businesses.

  3.4.4 Releases from individual facilities in the class consist
        primarily of a single hazardous material for which the
        releases from each facility can easily and generically be
        characterized and calculated.


3.5   Risk Assessments

  3.5.1 Health Risk Assessment Prioritization

        Within 90 days of completion of the review of all emissions
        inventory data for facilities specified in Section 1.2, the
        Air Pollution Control Officer shall, based on examination of
        the emissions inventory data and in consultation with the State
        Air Resources Board and the Office of Environmental Health
        Hazard Assessment, prioritize and then categorize those
        facilities for the purposes of health risk assessment.  This
        determination shall be made using the formulas listed in
        Subsections 3.5.1.1 through 3.5.1.3.

        Facilities with a total score (St) of ten or more in any
        category (carcinogen, acute or chronic) shall prepare a
        Risk Assessment.  This prioritization method is based on the
        California Air Pollution Control Officers Association
        (CAPCOA) Air Toxics "Hot Spots" Program Facility
        Prioritization Guidelines, Method 2, p. 13-21, California Air
        Resources Board (CARB), 1990.

            used in Subsections 3.5.1.1 through 3.5.1.3.

            Si    = Score for each substance

            St    = Score for all substances

            Ei    = Emissions rate for each substance, actual
                    lbs/year for carcinogens, yearly average
                    lbs/hour for substances which cause chronic
                    adverse health effects, and maximum lbs/hour
                    for substances which cause acute adverse
                    health effects

            Pi    = Cancer potency or reference exposure level
                    for each substance

            RP  = Receptor proximity adjustment factor is based on
                  the distance to the nearest occupied permanent

 3.5.2 Health Risk Assessment Submittal Deadline

       Within 150 days of the determination that a facility must
       prepare a Risk Assessment pursuant to Section 3.5, the
       operator of every facility that must prepare a Risk
       Assessment shall prepare and submit to the Air Pollution
       Control Officer a Health Risk Assessment pursuant to Section
       44361 of the Health and Safety Code.  A 30-day extension for
       the submittal of the Health Risk Assessment may be allowed if
       arranged prior to the due date.

 3.5.3 Identical Facilities Risk Assessments

       The Air Pollution Control Officer shall, except where site
       specific factors may affect the results, allow the use of a
       single Health Risk Assessment for two or more substantially
       identical facilities. 

 3.5.4 Health Risk Submittals to the District

       Each Health Risk Assessment shall be submitted to the Air
       Pollution Control Officer.  Each Health Risk Assessment shall
       be prepared in accordance with the Air Toxics "Hot Spots"
       Program Risk Assessment Guidelines published by the
       California Air Pollution Control Officers Association
       (CAPCOA) and Supplemental guidelines established by the
       District.  The use of the CAPCOA Guidelines shall be
       superseded by the use of the risk assessment guidelines when
       published by the Office of Environmental Health Hazard
       Assessment pursuant to Health and Safety Code Section 44360.

 3.5.5 Approval of Health Risk Assessments

       After receiving comments from the Office of Environmental
       Health Hazard Assessment , the Air Pollution Control Officer
       shall approve, or return for revision and resubmission and
       then approve, the Health Risk Assessment within 180 days of
       receipt.  If the Health Risk Assessment has not been revised
       and resubmitted within 60 days of the Air Pollution Control
       Officer's request of the operator to do so, the Air
       Pollution Control Officer may modify the Health Risk
       Assessment and approve it as modified.

 3.5.6 Public Notice of Community Risks

       Upon approval of the Health Risk Assessment, the District
       shall provide notice to all exposed persons regarding the
       results of the Health Risk Assessment if, in the judgment of the
       Air Pollution Control Officer, the Health Risk Assessment
       indicates there is a significant health risk associated with
       emissions from the facility.  The significant health risk
       threshold established is cancer risk levels greater than 1
       chance per 100,000, and hazard index scores greater than 1.

       If notice is required under this Subsection, the notice shall
       include only information concerning significant health risks
       attributable to the specific facility for which the notice is
       required.  Any notice shall be made in accordance with
       procedures specified by the Air Pollution Control Board.

       The two options available to facilities include:

   3.5.6.1   The District prepares the public notices, in the format
             approved by the Board, and mailing list.  The District
             then sends the public notification letters to persons
             exposed and owners of properties where significant
             risks exist.

   3.5.6.2   The Facility prepares an example public notification
             letter in the format approved by the Board, and a
             mailing list, for approval by the District.  Upon
             approval by the District, the facility then prepares the
             public notification letters and submits them to the
             District.  The District then sends the public
             notification letters to persons exposed and owners of
             properties where significant risks exist.

           Facilities required to complete the public notification
           process must participate in public meetings to discuss
           these risks.

           Facilities required to complete the public notification
           process must pay the District the actual cost of staff time
           required for the District to prepare, send, and respond
           to the public notices, at the District's billable rate of
           $80 per hour, and the cost of the mailing.


3.6    Risk Reduction Audits and Plans

 3.6.1 Risk Reduction Schedules

   3.6.1.1   Five Year Risk Reduction Implementation Schedule

           Whenever a Health Risk Assessment approved pursuant to
           Subsection 3.5.5 indicates, in the judgment of the
           District, that there is a significant risk associated
           with the emissions from a facility, the facility operator
           shall conduct an Airborne Toxic Risk Reduction Audit
           and develop a Plan to implement airborne toxic risk
           reduction measures that will result in the reduction of
           emissions from the facility to a level below the
           significant risk level within five years of the date the
           Plan is submitted to the District.  The significant risk
           threshold established is cancer risk levels greater than
           one chance per 100,000, and hazard index scores
           greater than one.  The facility operator shall implement
           measures set forth in the Plan in accordance with this
           Section.

   3.6.1.2   Expedited Implementation Schedule

           The period to implement the Plan required by Subsection
           3.6.1.1 may be shortened by the Air Pollution Control
           Officer, upon finding that it is technically feasible and
           economically practicable to implement the Plan to reduce
           emissions below the significant risk level more
           quickly, or if it finds that the emissions from the
           facility pose an unreasonable health risk.

   3.6.1.3   Extended Implementation Schedule

           The period to implement the Risk Reduction Plan may be
           lengthened by up to an additional five years, if the Air
           Pollution Control Officer finds that a period longer than
           five years will not result in an unreasonable risk to
           public health and that requiring implementation of the
           Plan within five years places an unreasonable economic
           burden on the facility operator or is not technically
           feasible.

 3.6.2 Risk Reduction Audit and Plan Due Date

       The Risk Reduction Audit and Plan shall be submitted to the
       District, within 180 days of the District's determination of
       significant risk, for review of completeness.  The
       District's review of completeness shall include a substantive
       analysis of the emission reduction measures included in the
       Plan, and the ability of those measures to achieve emission
       reduction goals as quickly as feasible.

 3.6.3 Extended Time Frame For Deficient Audits And Plans

       If the Audit and Plan does not meet the requirements for
       completeness, the facility shall correct the specified
       deficiencies identified by the District.  A facility operator
       shall submit a revised Audit and Plan addressing the
       deficiencies identified by the District within 90 days of
       receipt of a deficiency notice.

 3.6.4 Plan Implementation Progress Reports

       Progress on the emission reductions achieved by the Plan shall
       be reported to the District annually.

 3.6.5 Updated Plans Required

       If new information becomes available after the initial Risk
       Reduction Audit and Plan, regarding either air risks posed by
       a facility, or emission reduction technologies that may be
       used by a facility that would significantly impact risks to
       exposed persons, the Air Pollution Control Officer may
       require the Plan to be updated and resubmitted to the
       District.

 3.6.6 Audits and Plans - Required Contents

       A facility operator subject to this chapter shall conduct an
       Airborne Toxic Risk Reduction Audit and develop a Plan which
       shall include at a minimum all of the following:

   3.6.6.1   The name and location of the facility.

   3.6.6.2   The SIC code for the facility.

   3.6.6.3   The chemical name and the generic classification of
             the chemical.

   3.6.6.4   An evaluation of the ATRRMs available to the operator.

   3.6.6.5   The specification of, and rationale for, the ATRRMs
             that will be implemented by the operator. The Audit and
             Plan shall document the rationale for rejecting ATRRMs
             that are identified as infeasible or too costly.

   3.6.6.6   A schedule for implementing the ATRRMs.


 3.6.7 Self Conducted Audits And Checklist

       A self conducted Audit and Checklist instead of a full Risk
       Reduction Audit and Plan may be submitted to the District for
       any industry which is comprised mainly of small businesses
       using substantially similar technology if a self conducted
       audit protocol is developed by the California Air Resources
       Board and is approved by the District. 

 3.6.8 Preparers' Qualifications Requirements

       The Audit and Plan shall be prepared and certified as meeting
       the requirements of this Rule by an engineer who is
       registered as a professional engineer pursuant to Section
       6762 of the Business and Professions Code, by an individual who
       is responsible for the processes and operations of the site,
       or by an environmental assessor registered pursuant to
       Section 25570.3 of the California Health and Safety Code.
