Projects to reduce the amount of air pollution caused by particulates coming from the Oceano Dunes don't appear to be working. Testing shows the number of days with poor air quality on the Nipomo Mesa held steady, despite the addition of sand fencing and hay bales.

California State Parks spent more than a million dollars on the projects this past spring.

Larry Allen is the Air Pollution Control officer for San Luis Obispo County. He believes the problem can be fixed without putting an end to vehicle access on the dunes, but says some action needs to be taken.
