                        1994)

          1.0 Purpose

              The purpose of this rule is to improve ambient air quality by
              reducing air pollutant emissions  that  result  from  vehicle
              commute  trips  to  worksites  with  100 or more employees by
              increasing the average vehicle ridership (AVR)

          2.0 Applicability

              This rule shall apply to employers with 100 or more employees
              at  a  worksite where at least 40 employees  report  to  work
              between  6  and  10  a.m.  For the purpose of determining the
              applicability of this  rule,  the  number  of  employees at a
              worksite  is  determined  as the maximum number of  employees
              reporting  to that worksite  on  any  single  weekday  Monday
              through Friday during the current calendar or fiscal year.

                                 Plan pursuant to the procedures  listed in

                                 Hearing Board).

                                 update  its  Employer  Trip Reduction Plan
                                 once every year after plan  approval until
                                 such time as the performance  objective is
                                 achieved.   Such  plan updates are  to  be
                                 submitted every year  to  the  APCO  on or
                                 before   the   anniversary  date  of  plan
                                 approval.

                        6.2.3.8  An employer shall  revise and resubmit its
                                 Employer  Trip Reduction  Plan  within  90
                                 days  of  a final  determination  that  an
                                 element  of   an  approved  Employer  Trip
                                 Reduction Plan  violates  any provision of
                                 law  issued  by  an agency or  court  with
                                 jurisdiction to make such a determination.

                        for processing  from those employees who start work
                        during  the  peak  period,  all  survey  forms  not
                        returned  shall  be  counted   as  single  occupant
                        vehicles for purposes of calculating AVR.

                  8.1.4 If   60% or more of the survey forms  are  returned
                        for processing  from those employees who start work
                        during the peak period,  one-half  of  those survey
                        forms  not  returned  shall be assumed to have  the
                        same AVR as that calculated  from  the  response to
                        the surveys returned, and one-half shall be counted
                        as   single  occupant  vehicles  for  purposes   of
                        calculating AVR.

                  8.1.5 The  employer  shall  calculate  the  AVR  for  the
                        worksite  by dividing the total "employee-days" for
                        the survey  week  by  the total "vehicle trip-days"
                        for the survey week.
                         AVR=total  employee days/total vehicle
                             trip days

                        8.1.5.1  Employee-Days shall  be  determined by the
                                 total number of employees  who  start work
                                 or  are assigned to a worksite during  the
                                 peak  period  each  work day Monday though
                                 Friday of the survey  week.   Each  day of
                                 the  survey  week  that an employee starts
                                 work during the peak  period counts as one
                                 employee-day.   For example,  an  employee
                                 who starts work each  day  Monday  through
                                 Friday  of the survey week between 6  a.m.
                                 and 10 a.m.  counts as five (5) employees-
                                 days. The following procedures are used in
                                 totalling employee-days:

                             8.1.5.1.1 Employees  telecommuting  or are off
                                       due   to   a  compressed  work  week
                                       schedule are counted as reporting to
                                       the  worksite   in  calculating  the
                                       total employee-days.

                             8.1.5.1.2 The  following  employees   are  not
                                       included in the employee-days total:

                                8.1.5.1.2.1 Employees  not  working because
                                            of vacation, sickness, or other
                                            time off.

                                8.1.5.1.2.2 Employees  who  report   to   a
                                            different  worksite  or an off-
                                            site work related activity.

                                8.1.5.1.2.3 Disabled employees.

                        8.1.5.2  Vehicle  Trip  Days:   Vehicle  Trip  Days
                                 shall be determined as follows:

                                 The  total  number  of  vehicles  used  by
                                 employees  who  start work or are assigned
                                 to  the  worksite  each  work  day  Monday
                                 through  Friday  of the  survey  week.   A
                                 vehicle trip-day is  based on the means of
                                 transportation  used  for   the   greatest
                                 distance  of  an  employee's  home to work
                                 commute trip.  For example an employee who
                                 starts  work  during  the peak period  and
                                 arrives at the worksite  each  day  of the
                                 survey  week  Monday  through Friday in  a
                                 single occupant vehicle counts as five (5)
                                 vehicle    trip-days.     The    following
                                 numerical  values are used in  calculating
                                 the total vehicle trip-days:

                             8.1.5.2.1 Single   occupant   vehicle   (drive
                                       alone) equals one (1).

                             8.1.5.2.2 Carpool  equals  one (1) divided  by
                                       the number of people in the carpool.

                             8.1.5.2.3 Vanpool equals one  (1)  divided  by
                                       the   number  of  employees  in  the
                                       vanpool.

                             8.1.5.2.4 Motorcycle,     moped,     motorized
                                       scooter,  or  motor  bike equal  one
                                       (1).

                             8.1.5.2.5 Dedicated  compressed  natural   gas
                                       vehicle equals one-fourth (0.25)

                             8.1.5.2.6 Dedicated   propane  vehicle  equals
                                       one-half (0.50)

                             8.1.5.2.7 Dual  or  Flexible   fueled  vehicle
                                       equals three-fourths (0.75).

                             8.1.5.2.8 The  following  all equal  zero  (0)
                                       vehicle trip-days:

                                       Public transit vehicles
                                       Private buspool or club bus
                                       Vehicle under human power
                                       Pedestrians
                                       Electric Vehicle

              8.2  Random  Sample  Method:   The method described  in  this
                   section shall be followed when  an  employer  chooses to
                   use a random sample to meet the requirements of  Section
                   8.1.

                  8.2.1 Employers  with  400  or more employees at a single
                        worksite have the option  of  calculating AVR based
                        upon  a  random sample of the employee  population.
                        The random  sample  option  is  available  only for
                        worksites  where  400 or more employees start  work
                        during the peak period  (6:00  a.m.  through  10:00
                        a.m.).

                  8.2.2 The  size  of  the  random  sample depends upon the
                        number of employees who start  work during the peak
                        period at the worksite.  The means to determine the
                        minimum size of the random sample  is  described in
                        Section 8.3.2.

                  8.2.3 The  sample  shall  be  selected  as  described  in
                        Section  8.3.   Once  the  sample  group  has  been
                        selected,  the  employer  shall not send additional
                        survey  forms  to  employees  beyond  the  original
                        sample group.  Such additional  surveys  invalidate
                        the  results  of the survey and void the employer's
                        option to utilize the random sample method.

                  8.2.4 A high response rate is critical to ensure that the
                        random sample produces  an  accurate  AVR  for  the
                        worksite.   The  employer  should  make a concerted
                        effort to obtain a completed survey  form from each
                        employee in the sample.  All non-respondents in the
                        sample  will  be  treated as drive alone  commuters
                        (i.e commuting in a  single  occupant  vehicle) for
                        purposes of calculating the worksite AVR.

              8.3  Basic Random Sample Selection Methodology:

                  8.3.1 The  employer  shall  compile  a  complete list  of
                        employees  at the worksite, in alphabetical  order,
                        and assign a  consecutive  number to each employee.
                        The employer shall exclude form  the list employees
                        who are known to regularly start work  outside  the
                        6:00 a.m. through 10:00 a.m. peak period.

                  8.3.2 The   employer   shall   determine  the  number  of
                        employees to be included in the random sample using
                        the following formula, where  n  is the sample size
                        and  N  is the number of employees who  start  work
                        between 6:00 a.m. and 10 a.m.

                                           n=N/1+0.0026*(N-1)

                        A sample  of  size "n" based on this formula should
                        produce an AVR  with  a  sampling  error of at most
                        plus  or  minus  0.05,  with 95% probability.   The
                        sample size based on this  formula  is displayed in
                        the table below:

                        Number of Peak Period      Sample
                        Employees @ Worksite       Size

                        400 to 420                  200
                        421 to 440                  205
                        441 to 460                  210
                        461 to 480                  214
                        481 to 500                  218
                        501 to 550                  225
                        551 to 600                  235
                        601 to 650                  240
                        651 to 700                  248
                        701 to 750                  255
                        751 to 800                  260
                        801 to 850                  265
                        851 to 900                  270
                        901 to 950                  274
                        951 to 1000                 278
                        1001 to 1500                300
                        1501 to 2000                320
                        2001 to 3000                340
                        3001 to 4000                350
                        4001 to 6000                360
                        6001 to 10,000              370
                        >10,000                     380

                  8.3.3 In no case can the random sample size  be less than
                        indicated  in  the  above table.  The employer  may
                        choose to include a larger  number  of employees in
                        the  survey.   A  larger  sample group should  more
                        accurately represent the entire employee population
                        provided that the employer  obtains a high response
                        rate.

                  8.3.4 After  the  sample  size has been  determined,  the
                        employer shall use a  random  number list generated
                        by the District to select the sample.

          9.0 Fees

              The  fee  schedule for rule 9001 is contained  in  Rule  3130
              (Trip Reduction Plan Review Fee).

          10.0  Alternative Emission Control

              At the option  of  the Employer, with approval of the APCO an
              alternative vehicle  emission  reduction  program may be used
              which achieves emission reductions equal to  or  greater than
              those  that  would  have  been  achieved  if  the performance
              objectives of Rule 9001 were met, and that these  alternative
              measures  are  not  required by any other Federal, State,  or
              local control measure  or  regulatory  requirement.   Such an
              alternative  emission  reduction  program  shall  include  an
              update  and  progress  monitoring  report  to be submitted at
              least every year.

         11.0 Delegation Requirements

              A local jurisdiction may be delegated responsibility  for the
              implementation  of  this rule by the APCO providing that  the
              local trip reduction  ordinance  and program to implement the
              ordinance meet the requirements of  the California Health and
              Safety Code Section 40717(e).
