Overview of Applicable Rules
Simi Valley businesses may be regulated by: municipal nuisance and health provisions, the Ventura County Air Pollution Control District (VCAPCD) for stationary sources, and state or federal rules when applicable. Typical requirements include visible emissions limits, odor controls, equipment-specific permit limits, and recordkeeping. When a conflict exists, regional or state law may preempt local rules for air quality control.

Enforcement for stationary industrial and commercial emission sources is generally performed by the Ventura County Air Pollution Control District; municipal code violations (nuisance, smoke, odors) may be enforced by the City of Simi Valley Code Enforcement or Police.
