PROPOSED RULES

DEPARTMENT OF AGRICULTURE


[ Filed February 18, 2003, 1:42 p.m. ]

     Original Notice.

     Preproposal statement of inquiry was filed as WSR 01-17-118.

     Title of Rule: Secondary and operational area containment for bulk pesticides, WAC 16-229-010 through 16-229-480.

     Purpose: The current 2,500 gallon tank size restriction results in a substantial increase in the number of times the product (soil fumigant) is transferred, increasing the risk of accidental spills. Changing the rule to allow larger temporary field storage tanks of (10,000 gallons) will reduce the number of required deliveries and, consequently, the number of road miles in which accidental spills of the soil fumigants may occur. Fewer deliveries will also reduce the number of times the product is transferred which will substantially reduce the potential for accidental spills.

     Statutory Authority for Adoption: RCW 15.58.040 and 17.21.030 and chapter 34.05 RCW.

     Statute Being Implemented: RCW 15.58.020, 15.58.040 (2)(e) and 17.21.030 (1)(a).

     Summary: The current rule limits the size of pesticide temporary field storage containers to 2,500 gallons. This limitation has become a concern of applicators and growers who are using soil fumigants. Soil fumigants are often used at rates of fifteen to twenty-five gallons per acre and higher. A large percentage of soil fumigant users grow upwards of 400 acres of crops often on the same farm. Given the rate per acre and the number of acres to be treated, the current tank size is inadequate causing the temporary field storage tanks to be filled several times and increasing the chances of accidental spills. Increasing the size of temporary field storage containers will also allow more efficient deliveries by the tanker trucks that deliver the product because the capacity of full tanker truckloads is usually 4,800 to 5,000 gallons. Changing the current rule to allow larger temporary field storage tanks of up to 10,000 gallons will increase product storage and delivery safety for the following reasons:

     (1) Spills are most likely to occur during the transfer of product from trucks into temporary field storage tanks. It is less hazardous to have an operator empty a 5,000 gallon tank truck into a field storage tank that can hold at least that capacity rather than into a tank that can hold only a portion of that capacity thus requiring iterations of the transfer process to fill the containers.

     (2) Larger tank capacity will reduce the number of delivery road miles of soil fumigants and lessen the risk associated with driving. Without this increase in tank size field storage dealers will be forced to make multiple trips to and from the tanks, increasing exposure of trucks and drivers to delivery accidents.

     Reasons Supporting Proposal: There are already numerous 10,000 gallon temporary field storage tanks being used to store soil fumigants resulting in noncompliance with a rule that, from a storage standpoint, is technologically outdated. Growers, applicators, and transporters of soil fumigants will all be positively impacted by the proposed rules.

     Name of Agency Personnel Responsible for Drafting, Implementation and Enforcement: Cliff Weed, Natural Resources Building, 1111 Washington Street, Department of Agriculture, 2nd Floor, Olympia, WA 98504-2589, (360) 902-2036.

     Name of Proponent: Washington State Department of Agriculture, governmental.

     Rule is not necessitated by federal law, federal or state court decision.

     Explanation of Rule, its Purpose, and Anticipated Effects: The proposed language amends two sections of the current rule. First, the definition of temporary field storage in WAC 16-229-010(22) Temporary field storage, is amended. The proposal language will increase the allowable size of temporary field storage tanks used for storing soil fumigants from the current size of 2,500 to a maximum of 10,000 gallons. The current rule requirement that temporary storage tanks can't remain in one location for more than fourteen consecutive days is not changed but new language is added requiring that temporary fumigant tanks must be chemically compatible with the material being stored.

     Also, WAC 16-229-200 Primary containment of bulk liquid pesticides -- Temporary field storage, is amended to require that bulk pesticide storage containers which contain soil fumigants used for temporary field storage must have attached in a weatherproof enclosure, a recorded log of the date and time of each inspection.

     Changing the current rule to allow larger temporary field storage tanks of up to 10,000 gallons will increase product storage and delivery safety for the following reasons:

     (1) Spills are most likely to occur during the transfer of product from trucks into temporary field storage tanks. It is less hazardous to have an operator empty a 5,000 gallon tank truck into a field storage tank that can hold at least that capacity rather than into a tank that can hold only a portion of that capacity thus requiring iterations of the transfer process to fill the containers.

     (2) Larger tank capacity will reduce the number of delivery road miles of soil fumigants. Without this increase in tank size, field storage dealers will be forced to make multiple trips to and from the tanks, increasing exposure of trucks and drivers to delivery accidents.

     There are already numerous 10,000 gallon temporary field storage tanks being used to store soil fumigants resulting in noncompliance with a rule that, from a storage standpoint, is technologically outdated. Growers, applicators, and transporters of soil fumigants will all be positively impacted by the proposed rules.

     Requiring a record log to be attached to the container will give field inspectors a better idea of when the container was inspected. This record log will also provide the owner of the tank a history of the tank and the overall condition of the tank, thereby preventing the likelihood of tank failure.

     Proposal Changes the Following Existing Rules: See above for a description of changes.

     No small business economic impact statement has been prepared under chapter 19.85 RCW. RCW 19.85.030 (1)(a) requires that an agency prepare a small business economic impact statement (SBEIS) for proposed rules that impose a more than minor cost on businesses in an industry. The department concludes that the proposed rule amendments will not impose a more than minor cost on the regulated industry for the following reasons:

•     The proposed amendments do not require that larger temporary storage tanks be used; rather they give the flexibility to do so if needed by updating the current rule to reflect storage capacity trends in the industry.

•     The proposed amendment requiring that tanks must be compatible with the material being stored in them already appears in other sections of the current rule, therefore, this added language does not impose any additional cost on the regulated community. The proposed amendment simply makes the amended sections compatible with the rest of the rule.

•     The fourteen day requirement is also a part of the current rule and, therefore, does not impose any additional costs on the regulated industry. Again, the proposed amendment simply makes the amended sections compatible with the rest of the rule.

•     Finally, the department concludes that the proposed new requirement to keep, in a weatherproof enclosure, a recorded log of the date and time of each inspection does not impose a more than minor cost on the regulated industry. Current rule requires that temporary field storage containers must be checked on a daily basis for leakage and soundness when in use. Since site visits must already occur, the department does not believe that simply keeping an on-site record of that visit in a weatherproof enclosure constitutes more than a minor cost. The department believes that such a record helps verify required daily inspections and, therefore, helps insure safe use of temporary storage tanks.

     For the above reasons, the department does not believe that the proposed amendments impose more than a minor cost on business and a small business economic [impact] statement is not required.

     RCW 34.05.328 does not apply to this rule adoption. The Washington State Department of Agriculture is not a listed agency in RCW 34.05 [34.05.328] (5)(a)(i).
