People in the Five Cities Area are reporting thick smoke near the homes and in their neighborhoods.
CalFire SLO said the smoke is from a fuel reduction near Spooners Cove and people should not worry.
CalFire SLO is conducting up to 270 acres of prescribed burning on PG&E property just west of Diablo Canyon Nuclear Power Plant.
Resources on the fire include one bulldozer, five fire engines and two hand crews from CalFire SLO. Ventura County Fire is providing one helicopter, and PG&E will provide one helicopter with water drop capability and 8 Safety Infrastructure Protection Teams, according to the department.
Firefighters with CalFire say a northwest wind pushing from the backside of Diablo is bringing the smoke into the Pismo Beach and southern SLO County area.
The burn is expected to only be one day.
