Amend section 6452.2 to read: 

6452.2 Fumigant Volatile Organic Compound Emission Limits. 

(a) The Director shall establish field fumigant volatile organic compound (VOC) emission 

limits in the Annual Volatile Organic Compound Emissions Inventory Report issued pursuant to 

section 6452.4 for the Sacramento Metro, South Coast, Southeast Desert, and Ventura ozone 

nonattainment areas where the difference between emissions in the most recent inventory report 

and the benchmarks for that area is five percent or less of the benchmarks or exceeds the 

benchmarks listed below during the May 1 through October 31 time period: 

Ozone Nonattainment Area Total Agricultural and Structural VOC Emissions 

Inventory Benchmarks from May 1 to October 31

Sacramento Metro 820,000 lbs. (2.2 tons/day average) 

San Joaquin Valley 6,700,000 lbs. (18.1 tons/day average) 

South Coast 3,200,000 lbs. (8.7 tons/day average) 

Southeast Desert 340,000 lbs. (0.92 tons/day average) 

Ventura in 2011 1,200,000 lbs. (3.3 tons/day average) 

Ventura in 2012 and later 1,100,000 lbs. (3.0 tons/day average) 

(1) Notwithstanding (a), iIf a VOC emission limit is in effect pursuant to (a) that limit must 

remain in effect until the commissioner does not condition permits to include a fumigant 

emission allowance specified in (c)(1) or (d)(1), and does not deny any permit or notice of intent 

specified in (c)(2) or (d)(2) in order to comply with the fumigant emission limit for two 

consecutive years. 

(b) The Director shall calculate the field fumigant VOC emission limits specified in (a) by 

subtracting the nonfumigant pesticide VOC emissions from the total agricultural and structural 

VOC emissions inventory benchmarks. Nonfumigant pesticide product emissions will be the 

summation of the pounds of each pesticide product used multiplied by the VOC content 

(emission potential) for the specific product. 

(c) For the Ventura ozone nonattainment area, the commissioner shall ensure that the fumigant 

limits specified in (a) are not exceeded during the May 1 through October 31 time period using 

one or more of the following methods for field soil fumigations: 

(1) Condition permit to include fumigant emission allowances. 

(2) Deny any permit or notice of intent that would cause the fumigant limit to be exceeded. 

(3) Condition permit to prohibit or require any of the methods allowed by sections 6447.3(a), 

6448(c), 6449.1(b), 6450.1(d), or 6452 during the May 1 through October 31 time period. 

(d) For ozone nonattainment areas other than Ventura, the Director shall select one or more of 

the following methods to ensure the fumigant limits specified in (a) are not exceeded during the 

May 1 through October 31 time period: 

(1) The Director establishes a fumigant emission allowance for each permittee, based on 

information provided the commissioners within the ozone nonattainment area. The total 

allowances in each ozone nonattainment area must not exceed the fumigant limit established for 

that area. Commissioners shall issue permits or amend existing permits to comply with the 

fumigant emission allowance(s) established by the Director. Commissioners shall deny any 

notice of intent that does not comply with the permittees’ fumigant emission allowances. 
3 

 (2) Commissioners deny any permit or notice of intent that would cause the fumigant limit to 

be exceeded. 

(3) Commissioners condition permits to prohibit or require any of the methods allowed by 

sections 6447.3(a), 6448(c), 6449.1(b), 6450.1(d), or 6452 during the May 1 through October 31 

time period. 

(e) No person may apply a field fumigant during the May 1 through October 31 time period in 

an ozone nonattainment area for which a fumigant emission limit has been established pursuant 

to this section (a), unless their restricted material permit includes conditions specified in (c) or 

(d), or notice of intent is approved in writing. 

(f) For the San Joaquin Valley ozone nonattainment area, if the difference between emissions 

in the most recent emissions inventory report and the 6,700,000 pound (18.1 tons per day) 

benchmark for this area is five percent or less of the benchmark or exceeds this benchmark 

during the May 1 through October 31 time period, the provisions of section 6884 shall apply.

emissions inventory report must: 

(1) report the total agricultural and structural (fumigant and nonfumigant) pesticide volatile 

organic compound (VOC) emissions for the previous years. Nonfumigant pesticide product 

emissions will be the summation of the pounds of each pesticide product used multiplied by the 

VOC content (emission potential) for the specific product. Fumigant product emissions will be 

the summation of the pounds of each pesticide product used multiplied by the emission potential 

for that specific product and VOC emission rating for the application method, as specified in 

(54); 

(2) evaluate compliance with the total pounds of agricultural and structural VOC emissions 

specified in sections 6452.2; 

(3) establish fumigant emissions limits pursuant to section 6452.2 for the upcoming year; 

(4) establish an emission rating for each field fumigation method described in sections 6446.1, 

6447.3, 6448.1, 6449.1, 6450.1, 6450.2, 6451.1, or 6452. The emission rating will be expressed 

as a percentage of the amount of fumigant applied. The Director shall base the emission rating 

upon available scientific data documenting the VOC emissions.; 

(5) establish prohibitions on high-VOC nonfumigant products pursuant to section 6452.2(f), 

and if applicable, determine if prohibitions pursuant to section 6884(c) remain in effect; 

(6) establish a list of the nonfumigant products that are designated as low-VOC pursuant to 

section 6880; 

(7) establish a list of the actively registered nonfumigant products that are designated as highVOC pursuant to section 6880. 

(b) A draft emissions report shall be made available to the public for comment. A 45-day 

public comment period will be provided to allow for submission of written statements or 

arguments to the Director for review before finalizing the Annual Volatile Organic Compound 

Emissions Inventory Report. The emissions report will be posted on the Department's Web site. 
6 

(c) Low-VOC agricultural use products registered after the release of the Annual VOC 

Emissions Inventory Report and contain abamectin, chlorpyrifos, gibberellins, or oxyfluorfen as 

the primary active ingredient, will be listed in a supplemental report and posted on the 

Department's Web site. The products designated as low-VOC will be based upon the criteria 

established in section 6880. 

NOTE: Authority cited: Sections 11456, 12976, 14005, and 14102, Food and Agricultural Code. 

Reference: Sections 11501 and 14102, Food and Agricultural Code. 

Adopt section 6883 to read: 

6883. Pest Control Adviser Recommendation Requirements in the San Joaquin Valley 

Ozone Nonattainment Area. 

In the San Joaquin Valley ozone nonattainment area, the operator of the property shall not 

apply a high-volatile organic compound nonfumigant product specified in section 6881 during 

May 1 through October 31 to one of the following crops unless they obtain the written 

recommendation of a licensed agricultural pest control adviser: alfalfa, almond, citrus, cotton, 

grape, pistachio, and walnut. The operator of the property shall retain the written 

recommendation for at least two years after the application occurs. 

NOTE: Authority cited: Sections 11456, 12976, and 14102, Food and Agricultural Code. 

Reference: Sections 11501, 12003, and 14102, Food and Agricultural Code. 

Adopt section 6884 to read: 

6884. San Joaquin Valley Ozone Nonattainment Area Use Prohibitions. 

Pursuant to section 6452.2(f), the following shall apply to agricultural uses of high-volatile 

organic compound (VOC) products specified in the Annual VOC Emissions Inventory Report 

required in section 6881 containing abamectin, chlorpyrifos, gibberellins, or oxyfluorfen as the 

primary active ingredient in the San Joaquin Valley ozone nonattainment area during the May 1 

through October 31 time period. 

(a) No person may apply a nonfumigant product that has been designated as a high-VOC 

pursuant to section 6880 and as specified in the Annual VOC Emissions Inventory Report 

required by section 6881 on the following crops: alfalfa, almond, citrus, cotton, grape, pistachio, 

and walnut. If the product is not listed as a low-VOC, it cannot be used. 

(b) Notwithstanding (a), the following exceptions for use of high-VOC products are permitted: 

(1) Use of chlorpyrifos products to control aphids on cotton. 

(2) Use of gibberellins products when applied an application rate of eight grams of active 

ingredient per acre or less. 

(3) Uses for which the U.S. Environmental Protection Agency has issued an emergency 

exemption from registration under Section 18 of the Federal Insecticide, Fungicide, and 

Rodenticide Act. 

(4) Uses registered as a Special Local Need under Section 24(c) of the Federal Insecticide, 

Fungicide, and Rodenticide Act. 
7 

(5) Applications made by or under the direction of the U.S. Department of Agriculture, the 

California Department of Food and Agriculture, or county agricultural commissioner to control, 

suppress or eradicate pests. 

(6) Applications using precision spray technology meeting the criteria of the California Office 

of the Natural Resources Conservation Service’s Environmental Quality Incentives Program. 

(c) If prohibitions for high-VOC nonfumigant products are in effect pursuant to section 

6452.2(f), those prohibitions must remain in effect until the hypothetical VOC emissions shown 

in the Annual VOC Emissions Inventory Report comply with the limit specified in section 

6452.2(f) for at least two consecutive years. The hypothetical VOC emissions during a year of 

prohibitions shall be calculated for each active ingredient used on each crop specified in section 

6884. The hypothetical emissions shall be calculated by assuming the relative mixture of high 

and low-VOC products used in the current year of prohibitions would have been the same as in 

the most recent year without prohibitions. The VOC emissions are then calculated using that 

product mixture for the amount of active ingredient used in the current year. 

The following formula represents how the hypothetical VOC emissions described above would 

be calculated for each pesticide-crop combination: 

Hypothetical emissions 

for a pesticide-crop 

combination listed in 

section 6884 during 

May-Oct for the year 

of prohibitions 

= 

(Emissions for the pesticide-crop 

combination during May-Oct for the 

most current year without prohibitions) 

x 

(Pounds active ingredient for the crop 

during May-Oct for the year of 

prohibitions) 

Pounds active ingredient for the crop during May-Oct 

for the most current year without prohibitions 

The total hypothetical VOC emissions will be the summation of the hypothetical emissions for 

each pesticide-crop combination, plus the actual VOC emissions for the remaining pesticides and 

crops not listed in section 6880. 

NOTE: Authority cited: Sections 11456, 12976, and 14102, Food and Agricultural Code. 

Reference: Sections 11501 and 14102, Food and Agricultural Code. 

Adopt section 6886 to read: 

6886. Dealer Responsibilities for the San Joaquin Valley Ozone Nonattainment Area. 

Each licensed pest control dealer of a high-volatile organic compound (VOC) nonfumigant 

product specified in the Annual VOC Emissions Inventory Report, shall provide VOC 

information, in writing, to the purchaser at time of purchase or delivery pursuant section 6577 if 

the sale is made to or for the operator of the property with an operator identification number 

issued by a county agricultural commissioner in the San Joaquin Valley ozone nonattainment 

area.
