15.14.055 Hazardous/dangerous waste notification.
A. Any user that proposes to discharge any volume of hazardous waste as defined in 40 CFR 261 (listed or characteristic wastes) or dangerous waste as defined Chapter 173-303 WAC, or any facility that proposes to discharge any amount of acutely hazardous wastes as specified in 40 CFR 261.30(d) and 261.33(e), is required to provide a request in writing to the director. Discharging such waste without the director’s approval as provided herein is prohibited. The request shall be provided with the initial wastewater discharge approval application and repeated with each subsequent reapplication. Any user who the director has determined to be exempt from this requirement pursuant to Chapter 173-303 WAC shall comply with the requirements contained herein within 30 days of becoming aware of a discharge of hazardous or dangerous wastes in a calendar month or the discharge of acutely hazardous wastes to the city sewer system. Such notification shall include:
1. The name of the hazardous waste as set forth in 40 CFR Part 261 or the dangerous waste as set forth in Chapter 173-303 WAC;
2. The EPA/state hazardous/dangerous waste and/or site ID number;
3. The type of discharge (continuous, batch, or other); and
4. The estimated quantity of discharge of the hazardous, dangerous, or acutely hazardous waste.
B. If a user discharges such waste to the sewer system, the notification shall also contain the following information to the extent it is known or readily available to the industrial user:
1. An identification of the hazardous or dangerous constituents contained in the wastes;
2. An estimation of the mass and concentration of such constituents in the waste streams discharged during that calendar month; and
3. An estimation of the mass of constituents in the waste streams expected to be discharged during the following 12 months.
C. 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 or dangerous waste discharged to the degree it has determined to be economically practical and shall describe that program and reductions obtained through its implementation.
D. Any industrial user shall notify the EPA Regional Waste Management Division Director and the Washington State Department of Ecology, in writing, of the discharge into the POTW of a substance which, if otherwise disposed of, would be hazardous or dangerous waste under 40 CFR Part 261 and meets the reporting criteria specified at 40 CFR 403.12(p). Notification to the Washington State Department of Ecology and EPA is the responsibility of the industrial user and shall be made as required under 40 CFR 403.12(p). The industrial user shall copy the city on all notifications made to the Department of Ecology and EPA.
E. The discharge of any waste which classifies as a dangerous waste per Chapter 173-303 WAC and/or 40 CFR Part 261 is prohibited per BMC 15.14.020(B)(20), except as authorized by the director pursuant to subsections (A) through (D) of this section. Wastewater which would be a dangerous waste even if excluded from regulation under the domestic sewage exclusion (WAC 173-303-071) must be identified within each wastewater discharge approval application and subsequent reapplication.
F. Whenever the EPA/ECY publishes final rules identifying additional hazardous or dangerous wastes or new characteristics of hazardous or dangerous waste, a user shall notify the director of the discharge of such a substance within 90 days of the effective date of such regulations.
G. This reporting does not replace or render unnecessary the requirement for any other approvals and reporting that may need to occur or be required for the user per other federal, state, or local laws. These notification requirements do not apply to pollutants already reported under the self-monitoring requirements. [Ord. 2020-07-016 § 1; Ord. 2019-11-032 § 1].
