The fee and fee calculations change every year.

2024 Hazardous Waste Planning Fee calculation

This table shows the fee you can expect based on the pounds of dangerous waste (DW), extremely hazardous waste (EHW), and releases your business or facility reported.

If you generated and released 4,000 pounds or more, your fee is calculated using the formula provided by the Hazardous Waste Fee Regulation (WAC 173-305-220) along with the statewide rate per risk pound.

DW = dangerous waste; EHW = extremely hazardous waste; TRI = Toxics Release Inventory;
*Statewide rate per risk pound
Pounds generated
(DW + EHW)
TRI release
Fee Maximum fee
2,640 - 4,000 N/A $80 $80
4,000 and up 4,000 and up (DW + TRI + (EHW x 10)) x $0.092162* $26,207

Risk factors

We apply a risk factor for specific types of dangerous wastes and TRI releases:

  • State-only extremely hazardous waste (EHW) is multiplied by 10 times the current rate.
  • Both federal dangerous waste and state-only EHW are multiplied by the rate (risk factor of 1).
  • Federal dangerous wastes and TRI releases are multiplied by the rate (risk factor of 1).
