Isn’t the dust issue just a way for opponents of the SVRA to shut down OHV

activity on the dunes?

The   San   Luis   Obispo   County   Air   Pollution   Control   District   (APCD)   and   the   U.S.   Environmental   Protection Agency   have   been   monitoring   the   pollution   levels   and   have   confirmed   that   the   SVRA   has   been   in violation   of   state   and   federal   health   standards   and   the   APCD’s   Rule   1001 .      State   Parks   management has   acknowledged   that   the   dust   levels   are   unacceptable   and   pledged   to   correct   the   problem.      The California   Air   Resources   Board   has   developed   a   computer   model   showing   where   in   the   SVRA   excessive levels of PM are emitted.  The problem is real and must be corrected.

How will dust mitigation affect off-highway vehicle recreation at Oceano

Dunes?

The   Desert   Research   Institute   (DRI)   has   studied   the   SVRA   dune   dust   emissions   and   determined   the most   effective   mitigation   measures   would   involve   restoration   of   the   natural   vegetation   in   places where   the   PM   emissions   would   be   reduced   the   most.   Less   effective   measures   include   wind   fences   and hay   bales.      The   California   Air   Resources   Board   (CARB)   has   developed   a   computer   model   that   shows where   mitigation   measures   would   have   the   greatest   effect   and   still   minimize   the   impact   on   riding.      As a   member   of   the   Scientific   Advisory   Group   (SAG)   formed   as   part   of   the   Stipulated   Order   of   Abatement (SOA),   the   DRI   also   developed   a   computer   model   that   has   informed   SAG   recommendations.         This modeling   has   indicated   it   may   be   necessary   to   close   and   plant   vegetation   on   up   to   500   acres   of   riding area.      State   Parks   has   proposed   an   incremental   approach,   where   each   year   the   effect   of   dust   controls are   evaluated.      The   CARB   and   SAG   modeling   can   be   used   to   indicate   the   areas   where   controls   would   be most effective.
