Current through Register Vol. 49, No. 9, September, 2024

SECTION I. Title

The following regulations of the Arkansas State Plant Board, written pursuant to the Arkansas Pesticide Use and Application Act, Act 389ofl975,as amended, and the Arkansas Pesticide Control Act, Act 410 of 1975, as amended, shall be known as "The Arkansas Regulations On Pesticide Use". Promulgation of these regulations repeals all provisions of the Plant Board's current regulations entitled "Arkansas Regulations On 2,4-D, 2,4-DB, MCPA, And Other State Restricted Use Herbicides" effective December 31, 2002.

SECTION II. Purpose

Pesticides are valuable to the State's agricultural production and to the protection of man and the environment from insects, rodents, weeds and other forms of life which may be pests; but it is essential to the public health and welfare that they be regulated to prevent adverse effects on human life and the environment. However, at times certain pesticides present problems that were unanticipated by the manufacturer, the grower or the applicator. The purpose of these regulations is to provide additional mechanisms, other than denying registration of a product in Arkansas, to minimize the adverse effects of certain pesticides to:

1. Plants, including forage plants, or adjacent or nearby lands;

2. Wildlife in the adjoining or nearby areas;

3. Fish and other aquatic life in waters in reasonable proximity to the area to be treated; and

4. Humans, animals, or beneficial insects

SECTION III. Definitions

A. "Buffer Zone" means the distance an applicator must maintain between the field or area of application and a protected subject inside of which the subject pesticide may not be applied.

B. "Desirable Vegetation" means any type of vegetation the pesticide label specifically identifies for protection, vegetation for which the product is not labeled, or vegetation for which the owner/manager desires protection from the deposition of pesticides.

C. "Drift" means off target movement of a pesticide onto desirable vegetation, waterways, or where human health or the environment may be adversely impacted that occurs as a result of pesticide application.

D. "Custom Applicator" means a commercial applicator that applies pesticides assigned the Class E or F designation.

SECTION IV. General

The effective date of these regulations shall be January 1, 2003 and shall apply to all products registered for 2003. From that time forward, all pesticides registered for sale in the state of Arkansas shall be classified as Class A, B, C, D, E, F, or I. Such designation shall remain the same unless changed by the Arkansas State Plant Board by promulgation of a regulation so changing the designation. Whatever designation is assigned to a product by the Board, product dealers, users and applicators must comply with the restrictions for the assigned class. Such restrictions will apply to product uses allowed as a result of Section (18) or Section (24) actions under FIFRA except where the requirements on the label are clearly more restrictive than the Plant Board's requirements, in which case the more restrictive requirement must be followed.

The following designations apply to all pesticide products registered in the State of Arkansas. The use-restrictions itemized below are intended to be in addition to the product label. However, where the label is more restrictive than the applicable restrictions listed below, then the label shall be followed. Each successive Class designation below includes the restrictions defined in the designations that precede it.

SECTION V. Class A

All pesticides when registered in the state of Arkansas shall be classified as Class A unless research or experience has shown that certain potential problems may be inherent with the use of the product. Such knowledge may be as a result of but not limited to research findings, findings of other state and federal agencies or experience of the Arkansas State Plant Board. In such cases the Plant Board may, by regulation, place the product in another Class.

Products with this classification must be used in accordance with the label restrictions and other restrictions, if any, imposed by Plant Board regulations other than this document. Documentation of equipment set-up must be maintained by the commercial applicator on forms provided by the Plant Board and made available to the ASPB upon request. Insecticides that are intended to be applied in low volume, LV or Ultra Low Volume, ULV, and product label guidelines require droplet sizes designated as "fine" or smaller in accordance with the August 1999 issue of the ASAE S572 report entitled Spray Nozzle Classification by Droplet Spectra, shall not be required to comply with the Plant Board's regulations regarding spray droplet size. Said products must comply with the product label.

SECTION VI. Class B

Products with this designation shall be used in accordance with all other applicable federal or state laws and the regulations written pursuant thereto, the label registered with the State of Arkansas, regulations promulgated by the Board, the applicable restrictions identified for Class A and the following additional restrictions.

A. If enforcement action is taken against a Commercial, Non-Commercial or Private Applicator regarding drift of a product with this designation or a buffer zone violation, a part of the enforcement action will require the applicator to attend a drift control training class administered by the Plant Board or other training that is acceptable to the Plant Board.

SECTION VII Class C

Products with this designation shall be used in accordance with all other applicable federal or state laws and the regulations written pursuant thereto, the label registered with the State of Arkansas, the applicable restrictions identified for Class A and B above and the following additional restrictions.

A. All commercial equipment used to apply pesticides with this designation must be in compliance with the application equipment set up requirements specified for herbicide applications contained in the regulations written pursuant to the Pesticide Use and Application Act of 1975, as amended, (PUAA) prior to the initial application. Thereafter, said application equipment set up must be inspected annually by the Plant Board to verify compliance with the set up that was originally authorized. If the application equipment is modified it must again be authorized to be in compliance with the requirements for herbicide application contained in the before referenced regulations. The Plant Board will inspect all application equipment each year that is used to apply products with the Class C designation. A fee of $25 shall be charged for each Plant Board inspection.

Applications of products with this designation with equipment that is not acceptable to or has not been inspected by the Plant Board will be a violation of these regulations.

SECTION VIII Class D

Products with this designation shall be used in accordance with all other applicable federal or state laws and the regulations written pursuant thereto, the label registered with the State of Arkansas, the applicable restrictions identified for Class A, B, and C above and the following additional restrictions.

A. Applications may be made only when the wind is not blowing in the direction of desirable vegetation, waterways, or where human health or the environment may be adversely impacted. Where desirable vegetation, waterways, or human health and the environment cannot be protected by ensuring they are not downwind from the application site then, unless a greater distance is required by the label or other applicable State or Federal regulations, a 300 foot minimum buffer zone must be maintained between the protected entity (desirable vegetation, waterway, etc) and the sprayed area.

SECTION IX Class E

Products with this designation shall be used in accordance with all other applicable federal or state laws and the regulations written pursuant thereto, the label registered with the State of Arkansas, the applicable restrictions identified for Class A, B, C, and D above and the following additional restrictions.

A. Dealers Requirements

Should, at any time, a Custom Application Firm be left without an Operator-in-Charge or a pilot with an Individual Commercial Applicator Pilot License with Authorization to apply products with the Class E or F designation, either because of invalidation of the permit or for any other reason, such shall automatically invalidate the custom applicator's firm permit. It shall be a violation of these regulations for an individual or firm to act as a Custom Applicator that is not licensed to do so by the Plant Board.

8. The Plant Board or its authorized representative(s) may refuse issuance, after a hearing, of a custom applicator's permit to any applicant when such applicant has been found in violation of these regulations four times in a three year period. Such applicant may appeal to the Board. All requests for an appeal must be made in accordance with the Plant Board's policy on appealing a decision.

9. All equipment used for custom application of the products with this designation must have a decal provided by the Plant Board affixed to the device in a location where it can be easily seen by a Plant Board representative and protected from removal or disfigurement by work activity. This decal may only be affixed to equipment that meets the requirements set out in these regulations and other applicable regulations promulgated by the Plant Board. Use of equipment for custom application that does not have a current decal will be a violation of these regulations. Decals are not transferable between equipment. Each decal shall be issued at a cost of $50.00 each. Subsequent to issuance of a decal, the equipment on which the decal is to be attached will be subject to inspection by the Plant Board. Equipment found not meeting the requirements set out by these regulations or other applicable regulations promulgated by the Plant Board will be issued a Stop Use Order that will be released by the Plant Board once the Plant Board is satisfied that the equipment meets the set up requirements of the applicable regulations. The applicator will also be considered in violation of the Plant Board's regulations on pesticide application and be subject to the required enforcement action. All decals and permits expire on December 31st of each year.

a. The vehicle must be thoroughly decontaminated;

b. The tank must be thoroughly rinsed and the rinsate disposed of in accordance with the label. If the label does not address rinsate disposal, the rinsate should be collected and disposed of in accordance with applicable state and federal disposal laws; and c. The entire spray or application system must be replaced or decontaminated using the best available technology such that a sample taken from the successive pesticide tank load would contain no detectable concentration of the previous product. Where research has established a concentration below which no adverse affects occur and that concentration level is not a violation of state or federal law or regulations written pursuant to such laws, then that established concentration will be acceptable. Compliance with this provision in no way exempts the product user from compliance with any other responsibility imposed by state or federal law or regulation written pursuant thereto. Pesticide application equipment must have a leak free valve that is painted hunter orange from which a sample can be taken. Aircraft must have a sample valve located at the low point in the spray system. Ground application equipment must have a sample valve located in the pressure bypass line.
