12.16.220 Permit requirements for dangerous waste constituents.
Users discharging a waste stream containing dangerous wastes as defined in Chapter 173-303 WAC and/or 40 CFR (listed, characteristic, or criteria wastes) are required to comply with the following permit provisions:
(1) Obtain a written authorization to discharge the waste from the Public Works Superintendent, and either obtain specific authorization to discharge the waste in a state waste discharge permit issued by the Department, or accurately describe the waste stream in a temporary permit obtained pursuant to RCW 90.48.165. The description shall include at least:
(a) The name of the dangerous waste as set forth in Chapter 173-303 WAC, and the dangerous waste number;
(b) The mass of each constituent expected to be discharged;
(c) The type of discharge (continuous, batch, or other).
(2) Compliance shall be obtained on the following schedule:
(a) Before discharge for new users;
(b) Within 30 days after becoming aware of a discharge of dangerous wastes to the POTW for existing users; and
(c) Within 90 days after final rules identifying additional dangerous wastes or new characteristics or criteria of dangerous waste are published for users discharging a newly listed dangerous waste.
(3) Users must report all discharges of more than 33 pounds per month of substances which, if otherwise disposed of, would be hazardous wastes. Users must also report any discharge of acutely hazardous wastes as specified in 40 CFR 261.30(d) and 261.33(e). Subsequent months during which the user discharges more of a hazardous waste for which notice has already been provided do not require another notification to EPA or the state, but must be reported to the Public Works Superintendent.
(4) If new regulations under RCRA describe additional hazardous characteristics or substances as a hazardous waste, the user must provide notifications under subsection (1), if required by subsection (3) within 90 days of the effective date of such regulations.
(5) For any notification made under this section, the user shall certify that it has a program in place to reduce the volume and toxicity of hazardous wastes generated to the degree it has determined to be economically practical and shall describe that program and reductions obtained through its implementation.
(6) This provision does not create a right to discharge any substance not otherwise permitted to be discharged by this chapter, a permit issued thereunder, or any applicable federal or state law. (Ord. 445-N, §1, 2014)
