          (a) Purpose

              The purpose of this Rule is to provide employers with a menu 
              of options to reduce mobile source emissions generated from 
              employee commutes and to comply with federal and state Clean 
              Air Act requirements, including Section 182(d)(1)(B) of the 
              federal Clean Air Act or the alternative compliance mechanism 
              established with the District, the state, and federal 
              governments under the Environmental Protection Agency's 
              Project XL program.

          (b) Applicability

              Effective December 8, 1995, this rule applies to any employer 
              who employs 100 or more employees on a full or part-time basis 
              at a worksite for a consecutive six-month period calculated as 
              a monthly average, except as provided in subdivision (l) of 
              this rule.

          (c) Sunset Provision

              This rule shall be rescinded on December 31, 1998, or earlier,
              provided that a replacement measure is implemented which 
              produces an equivalent level of emission reductions and such 
              emission reductions are real, quantifiable, and surplus 
              relative to the most recently adopted state implementation 
              plan.

                      shall be subject to Rule 306, and evaluated and 
                      adjusted annually to reflect market forces.

              (8) Other Emission Reduction Strategies

                  Notwithstanding the foregoing provisions, any employer may 
                  receive credit toward its ERT for any emission reduction 
                  strategy that the employer or other person demonstrates to 
                  the Executive Office achieves real, quantifiable, 
                  enforceable, and surplus emission reductions for a 
                  discrete period of time.  Such strategies may include, but 
                  are not limited to, the reduction of non-work trips, other 
                  vehicle or engine accelerated turnover programs, 
                  investments in clean fuel infrastructure, clean fuel fleet 
                  purchases or conversion as specified in Regulation XVI,

                  discounts, and local community or development projects 
                  that reduce trip or energy demand or that expand clean 
                  fuel or high-occupancy travel options.  The Executive 
                  Officer shall not approve an alternative emission 
                  reduction program unless it is consistent with other 
                  District regulations and Governing Board policies, and 
                  shall consider guidelines established by the California 
                  Air Resources Board and the Environmental Protection 
                  Agency.

          (g) Vehicle Trip Emission Credits (VTEC)

              Employers may elect to implement any of the following 
              strategies and obtain vehicle trip emission credits that can 
              be applied towards their ERT.  Such actions are at the sole 
              discretion of the employer.

              (1) Peak Commute Trip Reductions

                  Employers may receive VTEC from employee commute 
                  reductions that occur during the peak window in 
                  accordance with the Rule 2202 - On-Road Motor Vehicle 
                  Mitigation Options Implementation Guidelines (adopted 
                  December 8, 1995).  VTEC obtained from peak commute 
                  trip reductions shall be determined according to the
                  following equation:
                          _                         _     _           _
                  VTEC = |   Creditable Commute      |   |  Emission   |
                         | Vehicle Reductions (CCVR) | X | Factor (EF) |
                         |_                         _|   |_           _|
                         
                  Where:

                          CCVR   = The daily average of total commute 
                                   vehicle reductions that are real, 
                                   surplus, and quantifiable.

                          EF     = Emission Factor in paragraph (m)(2) of
                                   this rule.

                  In calculating VTEC for the subsequent year, employers may
                  utilize data from previous years obtained by one of the 
                  following methods provided that employers maintain 
                  programs that would reasonably be expected to achieve an 
                  equivalent level of reductions during the subsequent year:

                  (A) Default data based on the weighted average of the
                      average vehicle ridership survey data of the previous 
                      three years, or

                  (B) Data obtained by conducting an average vehicle 
                      ridership survey in accordance with the Rule 2202 - 
                      Commute Reduction Program Guidelines, or

                  (C) Data obtained by an equivalent methodology approved 
                      by the Executive Officer or designee.

              (2) Other Work-Related Trip Reductions

                  Employers may receive additional VTEC from employee 
                  commute reductions that occur outside of the peak window 
                  or from non-commute vehicle usage calculated as creditable 
                  trip reductions and approved by the Executive Officer or 
                  designee.  VTEC obtained from other work-related trip 
                  reductions shall be determined according to the following 
                  equation:
                      _                                _     _           _
              VTEC = | Creditable Trip Reductions (CTR) | X |  Emission   |
                     |_     Conversion Factor (CF)     _|   |_Factor (EF)_|
                  
                  Where:

                          CTR   = The daily average of one-way trip 
                                  reductions that are real, surplus, and 
                                  quantifiable.  A round trip is considered 
                                  to be two one-way trips.

                          CF    = 2.0 for Peak Window trips; 2.3 for other
                                  trips.

                          EF    = Emission Factor in paragraph (m)(2) of 
                                  this rule.

              (3) Alternative Fuel Vehicles

                  Employers may receive VTEC for the use of alternative 
                  fuel vehicles (original equipment manufacturer (OEM) or 
                  converted) for commute or other work-related trips, in 
                  accordance with the Rule 2202 - On-Road Motor Vehicle 
                  Mitigation Options Implementation Guidelines (adopted 
                  December 8, 1995) and according to the following formula:

                   VTEC     =  [VT(NGs)] x [ 0.83 ] x [ EF ]
                            +  [VT(Ms)] x [ 0.80 ] x [ EF ]
                            +  [VT(Ps)] x [ 0.80 ] x [ EF ]
                            +  [VT(ZEVs)] x [ EF ]
                               
                               Conversion Factor (CF)

                  Where:

                          VT(NGs)  = Number of Vehicle Trips from natural 
                                     gas vehicles

                          VT(Ms)   = Number of Vehicle Trips from flexible 
                                     fuel vehicles operated on Methanol

                          VT(Ps)   = Number of Vehicle Trips from Propane 
                                     or LPG vehicles

                          VT(ZEVs) = Number of Vehicle Trips from Zero-
                                     Emission Vehicles

                          EF       = Emission Factor from paragraph (m)(2) 
                                     of this rule.

                          CF       = 2.0 for Peak Window trips; 2.3 for 
                                     other trips.

              (4) Vehicle Miles Traveled (VMT) Reduction Programs

                  Subject to approval of the Executive Officer or designee,
                  employers may elect to implement VMT reduction programs 
                  and receive VTEC towards their ERT.  Reduction of annual 
                  employee commute VMT may result from employment center 
                  relocation, video-conference centers, telecommuting 
                  centers or other alternative programs approved by the 
                  Executive Officer or designee.  The Executive Officer 
                  shall not offer any VTEC for a VMT reduction program 
                  unless it includes baseline VMT estimates and demonstrates 
                  that VMT reductions result in real, quantifiable,
                  and surplus emission reductions.

              (5) Parking Cash-Out Program

                  Employers may elect to implement a Parking Cash-Out 
                  Program to reduce employee commutes and receive VTEC 
                  toward their ERT.  Parking Cash-Out is a program where 
                  an employer offers to provide a cash allowance to an 
                  employee, equivalent to the parking subsidy that the 
                  employer would otherwise pay to provide the employee 
                  with a parking space.

          (h) General Emissions Credit Provisions:

              The following provisions shall apply to any of the emission
              credit strategies identified in this rule:

              (1) An employer or other person seeking credit under this 
                  rule may use actual annual mileage per vehicle, or 
                  alternative estimates of vehicle miles traveled (VMT) 
                  contained in Rule 2202 - On Road Motor Vehicle Mitigation 
                  Options Implementation Guidelines (adopted December 8, 
                  1995).   
             
              (2) Emission credit strategies that do not provide the precise
                  amount of surplus emission reductions for each of the 
                  three pollutants addressed by this rule (VOC, NOx, and CO) 
                  may still qualify for equivalent credit if the employer 
                  provides equivalent credits obtained pursuant to paragraph 
                  (h)(3) or the District achieves equivalent reductions 
                  through the Air Quality Investment Program.

              (3) Any person holding surplus emission credits, other than
                  vehicle trip emission credits (VTEC), pursuant to this 
                  rule may trade some or all of the those credits to other 
                  employers.

              (4) Upon the expiration of this rule, any unused emission
                  credits may be applied to other emission reduction 
                  programs pursuant to and consistent with District rules 
                  and regulations.

          (i) Program Administration

              Rule 2202 shall be administered according to the following:

              (1) Employers shall register with the District to implement 
                  an annual Emission Reduction Program for each worksite.  
                  Employers shall commence implementation of the approved 
                  Emission Reduction Program within 60 days of approval by 
                  the Executive Officer.  Existing Rule 1501 plans or 
                  Rule 1501.1 options shall remain in effect until an 
                  Emission Reduction Program is implemented.  The 
                  registration shall include the following information:

                  (A) The name of the highest ranking company official, the
                      name of the contact person, company address, telephone 
                      numbers for all participating worksites;

                  (B) The on-road vehicle mitigation option(s) that will be
                      used;

                  (C) The total number of employees that report to work in 
                      the peak window;

                  (D) The total number of employees at that worksite; and,

                  (E) Calculations for VOC, NOx, and CO emission reductions
                      for any of the on-road vehicle mitigation options in 
                      subdivision (f) or the vehicle trip emission credit 
                      options in subdivision (g).

              (2) Employers shall renew their registration annually.  
                  Annual registration shall include changes in employment 
                  base and any other changes that would necessitate 
                  adjustment in emission reduction targets or program 
                  implementation.

              (3) Employers may request to amend their Emission Reduction
                  Program at any time and implement the amendments with 
                  written approval of the Executive Officer subject to the 
                  criteria contained in paragraph (i)(1).

              (4) Rather than registering with the District for each
                  individual worksite, an employer may submit a single 
                  registration to implement an Emission Reduction Program 
                  that meets the aggregated ERT of several sites.

              (5) Emission credits obtained pursuant to subdivision (f) or
                  (g) shall be surrendered to the Executive Officer within 
                  the first six months of the approval of the registration 
                  forms.  The Executive Officer may grant extensions not to 
                  exceed six months on a case by case basis upon a finding 
                  that earlier compliance would present an unreasonable 
                  hardship.

              (6) Records which document the accuracy and validity of all
                  information submitted to the District as required by this 
                  rule shall be kept by the employer for a minimum of 
                  three years and made available upon request during normal 
                  business hours.

              (7) On a quarterly basis the Executive Officer shall recommend
                  to the District's Governing Board the release of monies 
                  from the AQIP restricted fund.  The program shall be 
                  administered and consideration of proposals shall be 
                  subject to the following:

                  (A) Proposals shall be accepted on an ongoing basis;

                  (B) Equal consideration shall be given to cost-effective
                      proposals and those that achieve long-term advancement 
                      of mobile source technology;

                  (C) The amount of emission reductions required to
                      demonstrate equivalent emission reductions shall be 
                      determined on a quarterly basis;

                  (D) The allocation of funding shall be recommended for
                      proposals that reduce equivalent emissions within each 
                      county proportional to the contribution level of 
                      employers within each county to the greatest extent 
                      feasible; and,

                  (E) The emissions reductions are demonstrated to be real,
                      quantifiable, enforceable, and surplus, in accordance 
                      with the Rule 2202 - On-Road Motor Vehicle Mitigation 
                      Options Implementation Guidelines (adopted December 8, 
                      1995).

              (8) Registration forms submitted by employers shall be subject
                  to the fee schedule set forth in subdivisions (c) and (d) 
                  of Rule 306.  Employers choosing to implement the Employee 
                  Commute Reduction Program under paragraph (l)(3) shall be 
                  subject to the fee schedule set forth in Rule 308.

              (9) Any employer subject to Rule 2202 or to the exemptions of
                  paragraph (l)(3) of this rule shall comply with the 
                  requirements of paragraphs (e)(2), (3), (4) and 
                  subdivision (k) of Regulation VII - Air Pollution 
                  Emergencies.

          (j) Previously Delegated Programs

              Any employer that is in compliance with an ordinance adopted 
              by a local government that has a trip reduction ordinance that 
              was approved by the District prior to the effective date of 
              this rule, and that has an existing memorandum of agreement 
              with the District, shall be deemed in compliance with this 
              rule.

          (k) Delegation to Local Governments

              The District may delegate authority to implement all or part 
              of Rule 2202, except for the provisions of paragraph (f)(7), 
              to any local government that satisfies the following criteria:

              (1) The local government adopts an ordinance that is at least
                  as stringent as Rule 2202 in the following areas:

                  (A) Applicability;
                  
                  (B) Emission reductions target;

                  (C) Vehicle trip emission credit calculations;

                  (D) Annual registration; and

                  (E) Recordkeeping.

              (2) The local government demonstrates to the satisfaction of
                  the Executive Officer that:

                  (A) It has an implementation plan providing adequate
                      resources to adopt and enforce the ordinance; and

                  (B) Multiple site employers with more than one regulated
                      worksite in the District have the option of complying 
                      with the District rule instead of the local ordinance.

              (3) The local government has executed a Memorandum of
                  Understanding with the Executive Officer specifying the
                  procedures to monitor and review performance of the local
                  government in implementing the program, and procedures for
                  revocation of delegation if the Executive Officer 
                  determines that performance of the local government is 
                  inadequate.

          (l) Exemptions

              (1) Employee Threshold

                  Any employer whose employee population at the worksite
                  decreases to fewer than 100 employees for the prior 
                  consecutive six month period, calculated as a monthly 
                  average; or fewer than 33 employees are scheduled to 
                  report to work Monday through Friday between 6-10 AM for 
                  the prior consecutive 90 days, may submit a written 
                  request to the Executive Officer or designee to be 
                  exempted from this rule.  Employers must submit a 
                  registration form not later than 90 days after they know 
                  or should have known that they no longer qualify for this 
                  exemption.

              (2) Declared Bankruptcy

                  An employer who has declared bankruptcy, for the official
                  business or governmental operations of its organization or
                  company, through a judicial court filing and confirmation
                  process, may request the Executive Officer to grant a 
                  temporary waiver from complying with the requirements of 
                  this rule.  Upon demonstration of the filing and 
                  confirmation of bankruptcy, the Executive Officer will 
                  grant an exemption for the duration of bankruptcy, not to 
                  exceed two (2) years, from the date of the waiver.

              (3) Employee Commute Reduction Program

                  Rather than comply with the provisions of subdivision (e) 
                  of this rule, employers may elect to implement an employee 
                  commute reduction program that demonstrates conformance 
                  with the Employee Commute Reduction Program Guidelines 
                  (adopted December 8, 1995).

                  (A) Performance Goal

                      Employers must provide a program that will be 
                      reasonably likely to result in achieving their average 
                      vehicle ridership goal within three years.  The goals 
                      shall be as follows:  1.75 for Performance Target 
                      Zone 1; 1.5 for Performance Target Zone 2; and 1.3 for 
                      Performance Target Zone 3.

                  (B) Supplemental Strategies

                      Notwithstanding the above, an employer may elect to
                      supplement its Employee Commute Reduction Program with 
                      any strategy listed in subdivisions (f) or (g) in 
                      order to achieve their goal.

              (4) Renewal Date

                  (A) The currently approved Rule 1501 Employee Trip 
                      Reduction Plan may remain in effect until the 
                      biennial renewal date.

                  (B) The currently approved Rule 1501.1 Registration may
                      remain in effect until the annual renewal date.

              (5) Primary and Secondary School Districts and Schools

                  Any public or private primary or secondary school district 
                  or school that buses two (2) students for every 
                  one (1) peak window employee at worksites subject to the 
                  rule is exempt from Rule 2202, according to the following 
                  criteria:

                  (A) School districts and schools shall keep records
                      demonstrating the maintenance of this ratio on-site 
                      and make them available upon request by the Executive 
                      Officer or designee; and

                  (B) On a case by case basis, the Executive Officer or
                      designee may approve a request by a school district or 
                      school to modify the default student-to-employee ratio 
                      to reflect location, trip length and other school 
                      district or school specific busing program 
                      characteristics in order to maintain equivalency with
                      emission reductions which would occur if the district 
                      or school met its emission reduction goals under 
                      Rule 2202; and

                  (C) The Executive Officer may periodically update and
                      publish the default student-to-employee ratio to 
                      reflect changes to revised emission factors published 
                      by the California Air Resources Board.

                  School districts and schools may opt not to be exempt but
                  to implement a Rule 2202 program and claim credit for 
                  surplus emission reduction credits earned through a 
                  student busing program and other Rule 2202 compliance 
                  options.

              (6) Primary and Secondary School District Financial Hardship

                  Due to their financial hardship, notwithstanding the 
                  criteria of paragraph (l)(5), school districts that have 
                  received a Negative or Qualified Certification status from 
                  their County Board of Education pursuant to Chapter 6, 
                  Part 24 of Division 3 of the Education Code, deeming that 
                  based upon current projections the school district or 
                  county office of education will not or may not meet its 
                  financial obligations, may request the Executive Officer 
                  to grant a temporary exemption from the requirements of 
                  the rule.  The Executive Officer shall grant a temporary 
                  exemption for the period during which the Negative or
                  Qualified Certification status applies.

          (m) Emission Factors

              The following emission factors, which shall be used in
              calculations pursuant to this rule, are based on California 
              Air Resources Board's EMFAC 7F emission factor model and 
              BURDEN 7F vehicle activity model. These emission factors shall 
              be revised upon publication by the California Air Resources 
              Board of final revised emission factors.

              (1) Employee Emission Reduction Factors

                  The following employee emission reduction factors (pounds 
                  per year per employee) shall be used in determining the 
                  Emission Reduction Target with respect to the worksite 
                  Performance Target Zone.  The Performance Target Zone is 
                  determined by the worksite location within the geographic 
                  boundaries as described in Attachment I and the Rule 2202 
                  - On-Road Motor Vehicle Mitigation Options Implementation
