VOCs IN PESTICIDES January, 1992 SJVUAPCD releases 1991 Air Quality Attainment Plan, which estimates VOC emissions from pesticides at 59 tons per day, or approximately 8% of the total VOC emissions inventory. June, 1992  Valley Research releases final report entitled "Day Specific Emissions Inventory of the San Joaquin Valley Air Quality Study", which estimates VOC emissions from pesticides at 80 tons per day. May, 1994  Federal EPA proposes "Federal Pesticide Rule" as part of the Federal Implementation Plan (FIP) levied against California. The proposed rule called for a mandatory 45% reduction in VOC emissions from pesticides within two years. Chemicals with high VOC contents would be targeted first, regardless of the actual quantity used. The Association testifies in opposition to EPA proposal at FIP hearing in Sacramento. The Association later submits written testimony in opposition to proposed EPA rule. September, 1994  The California Department of Pesticide Regulation (DPR) releases its own VOC proposal for pesticides. DPR proposal only asks for 20% reduction by 2005, and incorporates voluntary control measures, unless deemed necessary. 1995  DPR conducts "data call-in" to obtain VOC content information of pesticides from chemical manufacturers. June 1996  DPR conducts limited release of preliminary VOC emissions inventory, which estimates pesticide VOC emissions at 74.3 tons per day for the San Joaquin Valley. The Association comments on DPR proposal identifying problem areas. June, 1997  DPR publicly releases VOC emissions inventory, which estimates VOC emissions from pesticides at 72.5 tons per day in 1995 for the San Joaquin Valley. Cotton is identified as the leading emitter of VOC emissions from pesticides. KEY ISSUES DPR Requirements  Mandatory reformulation requirements may be triggered soon, if reduction is not verified. Could eliminate certain chemicals. Many chemicals have estimated VOC emissions rather than actual VOC emissions. New Ozone Standard  New ambient air quality standard for ozone will serve to put increased pressure on this previously "unregulated" activity.

VOC-  Volatile Organic Compound (VOC) means any compound of carbon excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides or carbonates, and ammonium carbonate, which participates in atmospheric photochemical reactions other than those defined as exempt compounds.
