set in consultation with the acoustical engineering contractor, normally during high
attendance months. The results of these tests are used to guide management in
addressing any problem areas.

The Grants Program awarded Education and Safety grant funding to the Southern
California Mountains Foundation for informational kiosks, free sound awareness
monitoring, and outreach at events and at OHV areas.

the aim of reducing the amount of dust generated by OHVs.

Oceano Dunes SVRA took steps in 2015 to reduce sediment and improve water
quality in surrounding areas. The SVRA installed a track-out prevention device at
public exits onto West Grand Avenue in Grover Beach and Pier Avenue in Oceano.
This device is similar to a rumble strip or cattle grate and is designed to prevent
or control sediment track-out. These track-out devices have been installed in the
ground and are not visible except from the area immediately near the device. These
devices are part of Oceano Dunes SVRA Particulate Matter Reduction Plan, which
is mandated by local San Luis Obispo County Air Pollution Control District (APCD)
Rule 1001, Coastal Dunes Dust Control Requirements.

In 2014, Ocotillo Wells SVRA entered into a contract with Michael Baker
International to develop a pilot treatment and testing program for various dust
control treatments and measure their effectiveness. Various treatments include
dust palliatives, wind barriers, and signage on selected park roads and trails.
Monitors used during the project to collect fugitive dust data relative to the treatment
processes included the truck-mounted TRAKER III (Testing Re-entrained Aerosol
Kinetic Emissions from Roads) and several stationary monitoring towers. The
TRAKER III measures the mass concentration of the dust plume at the rear of the
vehicle created by its travel over unpaved surfaces. The stationary towers measure
wind speed and direction, temperature, relative humidity, atmospheric pressure, and
particulate matter number concentrations.
The project findings are expected to deliver a full summary of the activities
conducted and data collected during the study as well as an evaluation of
the effectiveness and efficiency of both individual dust control practices and
combinations of practices. The findings will help Ocotillo Wells SVRA to comply
with the Imperial Valley APCD Rule 800 mandate for regulating fugitive dust within
the park boundaries. Rule 800 provides general requirements for control of fine
particulate matter, most prominently the level of Particulate Matter of 10 Micron
(PM10) particulates.
