Rinsate management.
(1) Pesticide products, or rinsates spilled, or accumulated within a secondary or operational area facility, shall be immediately recovered. Any use of these materials shall be at labeled rates consistent with labeled end uses for the product(s). The materials may be stored for later use or as make-up water for pesticide applications.

(3) Recovered spills, sedimentation, rinsates, contaminated precipitation or other contaminated debris shall be contained and used per product label or properly disposed of. Pesticide containing materials shall not be released to the environment unless the release is an application per product label direction. Any disposal of these materials or captured washwater shall be consistent with the Hazardous Waste Management Act, chapter 70.105 RCW and the Water Pollution Control Act, chapter 90.48 RCW and shall be enforced by the Washington state department of ecology accordingly.
(4) If storage tanks are used to store rinsate, washwater or contaminated precipitation for later use the following records shall be kept.

Operational area containment at permanent mixing/loading sites.
(1) All operational area activities shall take place on or within operational area containment[:]
(2) Operational area containment shall be designed and constructed to contain pesticides, rinsates, washwater and other materials spilled or deposited during mixing, loading, unloading, draining, [and] rinsing and washing activities.
(7) Operational area containment shall be of adequate size and design to contain one hundred twenty-five percent the capacity of the largest storage container, or application equipment used at the facility up to a maximum of fifteen hundred gallons.
(8) Operational area containment constructed prior to March 1, 1994, and which have been constructed to contain one hundred ten percent of the capacity of the largest storage container or application equipment used at the facility shall be considered to be in compliance with this chapter.
(9) Operational area containment shall slope to one or more liquid tight collection points or sumps that allows spilled or deposited materials to be easily recovered. An above ground storage container may be used in conjunction with the operational area containment to meet the capacity requirement. If an above ground storage container(s) are used for temporary storage, the storage containers shall be located within operational area or secondary containment. The storage container shall be clearly and conspicuously labeled "pesticide rinsate" followed by the major category of pesticide such as insecticide, herbicide, fungicide.
