Volatile Organic Compound (VOC) Emissions from Pesticides
Volatile organic compounds (VOCs) contribute to the formation of ground-level ozone, which is harmful to human health and vegetation when present at high enough concentrations. The federal Clean Air Act requires each state to submit a State Implementation Plan (SIP) for achieving and maintaining federal ambient air quality standards, including the standard for ozone. Nonattainment areas (NAAs) are regions in California that do not meet either federal or state ambient air quality standards. California’s Air Resources Board (ARB) and DPR developed a plan to track and reduce pesticidal sources of VOCs in NAAs as part of the California SIP to meet the ozone standard. DPR is responsible for agricultural and commercial structural pesticide products, and ARB is responsible for pesticides in consumer products.
