Wash. Admin. Code § 16-201-230 – Fertilizer spill and rinsate management

(1) Fertilizer spills within secondary containment or operational area containment shall be immediately recovered.
(2) Fertilizer rinsate shall be removed from secondary containment and operational area containment as necessary to ensure the capacity of the containment area does not fall below the levels required by this chapter. [Rinsate] accumulations collected in an operational area water-tight sump shall not exceed the capacity of the sump at the end of the business day.
(3) Fertilizer spills or rinsates shall not be released to the environment unless the material is applied at normal fertilizer rates, used in fertilizer blends, used in a fertilizer manufacturing process, or disposed of properly.
(4) Recovered spills or rinsates in excess of 500 gallons must be contained in a storage container within secondary containment. The storage container must be clearly and conspicuously labeled to identify the content.
Reviser's note: RCW 34.05.395 requires the use of underlining and deletion marks to indicate amendments to existing rules, and deems ineffectual changes not filed by the agency in this manner. The bracketed material in the above section does not appear to conform to the statutory requirement.
