- Number and size of containers approaching the 90- or 180-day accumulation time limit.
- General description of the waste.
- Accumulation start date of the waste.
- Specific location (accumulation area) of the waste.
- Documentation of the efforts you have made to schedule waste pickup.
- Explanation as to why the dangerous waste must remain on-site due to unforeseen, temporary, and uncontrollable circumstances.
- Copy of the most recent weekly inspection log.
- Name and phone number for the on-site emergency coordinator.
After we complete our review, we will notify you of our decision.
MQGs must stay below the maximum allowable limits to remain conditionally exempt from a storage permit. MQGs become subject to treatment, storage, disposal (TSD) facility requirements (WAC 173-303-600) when they exceed:
- 6,600 pounds of dangerous waste,
- 2.2 pounds of acutely hazardous waste
- 2.2 pounds of toxic extremely hazardous waste.
In this situation, an MQG must immediately ship waste off-site to stay below these thresholds.
SQGs become subject to LQG conditions for exemption until all dangerous waste is shipped off-site.
