LAST REVISED 07/09/93



(Adopted May 7, 1976)(Amended November 6, 1992)(Amended July 9, 1993)

          RULE 403.    FUGITIVE DUST

          (a)  Purpose
               The  purpose  of  this  rule  is  to  reduce the amount of
               particulate  matter  entrained  in the ambient  air  as  a
               result of anthropogenic (man-made)  fugitive  dust sources
               by  requiring  actions  to  prevent,  reduce  or  mitigate
               fugitive dust emissions.

          (b)  Applicability
               The provisions of this rule shall apply to any activity or
               man-made condition capable of generating fugitive dust.

          (c)  Definitions
               (1)  ACTIVE OPERATIONS shall mean any activity capable  of
                    generating  fugitive dust, including, but not limited
                    to, earth-moving  activities, construction/demolition
                    activities,  or  heavy-   and   light-duty  vehicular

                    subparagraph  (e)(3)(C),  a  justification  statement
                    must be provided  in lieu of the description required
                    in   subparagraph   (e)(3)(D).    The   justification
                    statement must explain  the  reason(s) why reasonably
                    available control measures cannot be implemented.
               (5)  Within  30 calendar days of the  receipt  of  a  plan
                    submitted  pursuant  to  subparagraph  (e)(1)(B), the
                    Executive  Officer will either approve, conditionally
                    approve, or  disapprove the plan , in writing.  For a
                    plan to be approved  or conditionally approved, three
                    conditions must be satisfied:
                    (A)  All sources of fugitive  dust  emissions must be
                         identified (e.g., earth-moving,  storage  piles,
                         vehicular traffic on unpaved roads, etc.).
                    (B)  For   each   source  identified,  at  least  one
                         reasonably available  control  measure  must  be
                         implemented,   or  an  acceptable  justification
                         statement pursuant  to  paragraph (e)(4) must be
                         provided; and
                    (C)  If, after implementation  of  control  measures,
                         visible dust emissions are crossing the property
                         line(s),   then   contingency   measures  (e.g.,
                         increased   watering)  must  be  specified   for
                         immediate implementation.
               (6)  Conditional approval  will  be made if conditions are
                    met, but the stated measures  do  not  satisfactorily
                    conform  to  the guidance contained in the  Rule  403
                    Implementation  Handbook.  If a plan is conditionally
                    approved, the conditions necessary to modify the plan
                    will  be  provided   in   writing  to  the  person(s)
                    identified   in   subparagraph    (e)(3)(A).     Such
                    modifications  must  be  incorporated  into  the plan
                    within  30  days  of  the  receipt  of  the notice of
                    conditional   approval,   or   the   plan   shall  be
                    disapproved.   A  letter  to  the  Executive  Officer
                    stating  that such modifications will be incorporated
                    into the plan shall be deemed sufficient to result in
                    approval of the plan.
               (7)  If a plan is disapproved by the Executive Officer:
                    (A)  The reasons  for  disapproval  shall  be given to the
                         applicant in writing.
                    (B)  Within 7 days of the receipt of a  notice  of  a
                         disapproved  plan,  the  applicant  shall comply
                         with the actions specified in Tables 1 and 2 for
                         each  applicable source of fugitive dust  within
                         the property lines.
                    (C)  The applicant  may  resubmit  a plan at any time
                         after receiving a disapproval notification,  but
                         will   not   be   relieved   of  complying  with
                         subparagraph (e)(7)(B) until such  time  as  the
                         plan has been approved.
               (8)  Failure  to  comply  with any of the provisions in an
                    approved or conditionally  approved  plan  shall be a
                    violation of subdivision (e).
               (9)  Any approved plan shall be valid for a period  of one
                    year   from  the  date  of  approval  or  conditional
                    approval  of  the  plan.   Plans  must be resubmitted
                    annually,  at least 60 days prior to  the  expiration
                    date, or the  plan shall become disapproved as of the
                    expiration date.   If  all  fugitive dust sources and
                    corresponding reasonably available  control  measures
                    or  special  circumstances  remain identical to those
                    identified  in  the  previously  approved  plan,  the
                    resubmittal may contain  a  simple  statement  of no-
                    change.   Otherwise,  a  resubmittal must contain all
                    the items specified in subparagraphs (e)(3)(A through
                    D).
               (10) Any person subject to the  requirements  of paragraph
                    (e)(1) who no longer exceeds, and does not  expect to
                    exceed  for  a  period  of  at  least  one  year, the
                    criteria   for   a  large  operation  may  request  a
                    reclassification as a non-large operation.  To obtain
                    this reclassification, a person must submit a request
                    in writing to the  Executive  Officer  specifying the
                    conditions  which  have  taken  place  to reduce  the
                    disturbed  surface  area  and/or the earth-moving  or
                    throughput conditions to levels  below  the  criteria
                    for large operations.  A person must further indicate
                    that  the  criteria  for  large  operations  are  not
                    expected  to  be  exceeded  during the subsequent 12-
                    month  period.  The Executive  Officer  shall  either
                    approve  or disapprove the reclassification within 60
                    days from  receipt  of  the reclassification request.
                    The Executive Officer will  disapprove the request if
                    the indicated changes can not be verified to be below
                    the criteria for large operations.   If approved, the
                    person  shall  be relieved of all requirements  under
                    subdivision (e).   Any  person  so reclassified would
                    again be subject to the requirements  of  subdivision
                    (e) if at any time subsequent to the reclassification
                    the criteria for large operations are met.
               (11) A   person   responsible  for  more  than  one  large
                    operation at non-contiguous sites may submit one plan
                    covering multiple sites provided that:
                    (A)  the contents  of the plan apply similarly to all
                         sites; and
                    (B)  specific information  is provided for each site,
                         including,  map  of  site   location,   address,
                         description of operations, and a listing  of all
                         sources  of  fugitive  dust emissions within the
                         property lines.

               (f)  Compliance Schedule
               All  newly amended provisions of this  rule  shall  become
               effective  upon adoption of this Rule Amendment.  Pursuant
               to subdivision  (e),  any  fugitive  dust emission control
               plan  which  has  been approved or conditionally  approved
               prior to the date of  adoption  of  these amendments shall
               remain in effect and the plan approval  date  shall remain
               unchanged.  If any changes to such plans are necessary  as
               a  result  of  these amendments, such changes shall not be
               required until the  annual  resubmittal  date, pursuant to
               paragraph (e)(9).

          (g)  Exemptions
               (1)  The provisions of this rule shall not apply to:

                         with any officially declared disaster  or  state
                         of emergency.
                    (D)  Active operations conducted by essential service
                         utilities  to  provide electricity, natural gas,
                         telephone, water  and  sewer  during  periods of
                         service outages and emergency disruptions.
                    (E)  Any   contractor  subsequent  to  the  time  the
                         contract  ends,  provided  that  such contractor
                         implemented    reasonably    available   control
                         measures during the contractual period.
                    (F)  Any grading contractor, for a  phase  of  active
                         operations,   subsequent   to   the  contractual

                         activities, provided that  reasonably  available
                         control  measures  have  been implemented during
                         the  entire  phase  of earth-moving  activities,
                         through and including  five days after the final
                         grading inspection.
                    (G)  Weed abatement operations  ordered  by  a county
                         agricultural  commissioner or any state, county,
                         or municipal fire department, provided that:
                         (i)  mowing, cutting or other similar process is
                              used which  maintains weed stubble at least
                              three inches above the soil; or
                         (ii) any discing or similar operation which cuts
                              into and disturbs  the  soil  is  used  and
                              meets the following conditions:
                              [a]  A  determination  is  made  by  the issuing
                                   agency  of  the  weed abatement  order
                                   that, due to fire  hazard  conditions,
                                   rocks, or other physical obstructions,
                                   it  is  not  practical  to  meet   the
                                   conditions    specified    in   clause
                                   (g)(1)(G)(i); and
                              [b]  Such determination is made in  writing
                                   and  provided to the person conducting
                                   the weed  abatement operation prior to
                                   beginning such activity; and
                              [c]  Such written determination is provided
                                   to the Executive  Officer upon request
                                   from  the person conducting  the  weed
                                   abatement operation.
                              (Note: The provisions of clause (g)(1)(G)(ii) do
                              not exempt the  owner  of any property from
                              controlling    fugitive   dust    emissions
                              emanating  from  disturbed   surface  areas
                              which have been created as a result  of the
                              weed abatement actions.)
               (2)  The  provisions of paragraphs (d)(1) and (d)(3) shall
                    not apply:
                    (A)  When  wind  gusts  exceed  25  miles  per  hour,
                         provided that:
                         (i)  Reasonably  available  control measures for
                              high  wind conditions are  implemented  for
                              each applicable  fugitive dust source type,
                              as specified in Table 1, and;
                         (ii) Records are maintained  in  accordance with
                              clauses  (e)(1)(A)(iii), (e)(1)(A)(iv)  and
                              (e)(1)(A)(v); and
                         (iii)In the event  there  are  technical  (e.g.,
                              non-economic)  reasons,  including  safety,
                              why any of the reasonably available control
                              measures  in  Table 1 cannot be implemented
                              for  one  or  more   fugitive  dust  source
                              categories, a person submits  a  "High Wind
                              Fugitive Dust Control Plan" (HW-Plan).  The
                              HW-Plan must further provide an alternative
                              measure   of  fugitive  dust  control,   if
                              technically  feasible.   Such  plan will be
                              subject to the same approval conditions  as
                              specified   in   subparagraphs  (e)(5)  and
                              (e)(6);
                    (B)  To unpaved roads, provided such roads:
                         (i)  are  used  for  the  maintenance  of  wind-
                              generating equipment; or
                         (ii) meet all of the following criteria:
                              [a]  are less than 50  feet in width at all
                                   points along the road;
                              [b]  are  within 25 feet  of  the  property
                                   line; and
                              [c]  have a  traffic  volume  less  than 20
                                   vehicle-trips per day.
                    (C)  To  any active operation, open storage pile,  or
                         disturbed   surface  area  for  which  necessary
                         fugitive dust  preventive  or mitigative actions
                         are  in  conflict  with  the federal  Endangered
                         Species Act.
                    (D)  To non-routine or emergency maintenance of flood
                         control channels and water spreading basins.
               (3)  The  provisions  of  paragraphs (d)(1),  (d)(2),  and
                    (d)(3) shall not apply to:
                    (A)  Blasting operations which  have been permitted by the
                         California Division of Industrial Safety; and
                    (B)  Motion picture, television, and video production
                         activities when dust emissions  are required for
                         visual   effects.   In  order  to  obtain   this
                         exemption,  the  Executive  Officer must receive
                         notification  in writing at least  72  hours  in
                         advance of any such activity.
               (4)  The provisions of paragraph (d)(3) shall not apply if
                    the dust control actions,  as  specified  in Table 2,
                    are   implemented   on   a  routine  basis  for  each
                    applicable fugitive dust source type.  To qualify for
                    this exemption, a person must:
                    (A)  maintain records to document the dates of active
