NOTICE TO PESTICIDE REGISTRANTS
REGARDING THE NEED FOR DATA IN ORDER TO ESTIMATE THE
VOLATILE ORGANIC COMPOUND EMISSION POTENTIAL
OF REGISTERED PESTICIDE PRODUCTS
The federal Clean Air Act Amendments of 1990;
U.S.C. section 7401 et seq.) require that states
develop state implementation plans for implementing,
maintaining, and enforcing National Ambient Air
Quality Standards for pollutants in each air quality
control region of the state. One of the pollutants
of concern is volatile organic compounds (VOC),
including VOCs released into the atmosphere from
pesticide product formulations. VOCs can react in
the atmosphere in the presence of sunlight with
nitrogen oxides to form ozone. Ozone is harmful to
both human health and vegetation.
On November 15, 1994, the Department of Pesticide
Regulation (DPR) prepared a State Implementation Plan
for agricultural and commercial structural
pesticides. The plan is designed to reduce VOC
emissions from such pesticides by a minimum of 20
percent from the 1990 baseline emission inventory to
the year 2005. DPR intends to produce VOC emission
inventories each year starting with 1990 and going
through 2005.
In order to produce the inventories, DPR needs data
regarding the VOC emission potential of each
registered agricultural or commercial structural
pesticide product. To begin obtaining the
information, DPR placed registered pesticide products
into reevaluation. Products formulated as liquids
were placed into reevaluation in April 1994 and
products formulated as solids were placed into
reevaluation in March 1995. In 1996, due to time
constraints, DPR estimated the amount of VOC in
currently registered pressurized products.
The data gathered through the reevaluation process
and estimated for pressurized products are being
used, in combination with use report information, to
calculate VOC emission inventories for 1990 through
1993. In order to calculate emission inventories for
California Notice 96-5

future years, VOC emission data are needed for
products which were registered in California after
the initiation of the two reevaluations. In
addition, as new agricultural and commercial
structural products are registered for use in
California, DPR will need VOC emission data for each
of the products.
Due Dates
If you intend to submit thermogravimetric
analysis (TGA) data on agricultural and commercial
structural pesticide products which are currently
registered, but were not included in either the
liquid or the solid reevaluation, please submit the
results by October 1, 1996. If we do not receive TGA
data by October 1, 1996, DPR will assign the VOC
emission potential of each product to be the highest
representative TGA value reported for products of the
same formulation category.
DPR also needs VOC emission data for each new
agricultural and commercial structural pesticide
product registered for use in California. Please
note that the TGA data are not required for
registration and failure to submit such data will not
hold up the registration process. If you intend to
submit TGA data, it may be submitted with the
application for registration or any time prior to
October 1 of the year in which the product is
registered. If we do not receive TGA data before
October 1 of the year in which the product is
registered, DPR will assign the VOC emission
potential of the product using the highest
representative TGA value reported for products of the
same formulation category.
Copies of TGA Protocols and VOC Data Submission Forms
Copies of TGA protocols for pesticide products
formulated as liquids, solids, and pressurized
products, as well as VOC Data Submission Forms, are
available upon request. The VOC Data Submission
forms are available in hard copy and on diskette in
Excel 5.0 format. Please note that a separate VOC
Data Submission Form must be submitted for each
product.
