Conditions for exemption for a large quantity generator that accumulates dangerous waste.

Large quantity generators, not to include transporters as referenced in WAC 173-303-240(3), may accumulate dangerous waste on site without a permit or interim status, and without complying with the requirements of WAC 173-303-600 provided that all of the following conditions for exemption listed in this section are met.

(1) Off-site shipments. All dangerous waste is shipped off site to a designated facility or placed in an on-site facility which is permitted by the department under WAC 173-303-800 through 173-303-845 or recycled or treated on site in ninety days or less. A generator who accumulates dangerous waste for more than ninety days is an operator of a storage facility and is subject to the facility requirements of this chapter and the permit requirements of this chapter as a storage facility unless they have been granted an extension to the ninety-day period allowed pursuant to subsection (2) of this section;

(2) Accumulation time limit.

(a) The generator accumulates dangerous waste on site for no more than ninety days unless;

(i) The department has granted a maximum thirty-day extension to this ninety-day period. The department may, on a case-by-case basis, grant a maximum thirty-day extension to this ninety-day period if dangerous waste must remain on site due to unforeseen, temporary and uncontrollable circumstances; or

(ii) The F006 accumulation conditions for exemption in subsection (13) of this section are met.

(b) For the purposes of this section, the ninety-day accumulation period begins on the date that:

(i) The generator first generates a dangerous waste; or
