Any user that is discharging more than 15 kilograms of hazardous wastes as defined in 40 CFR 261 (listed or characteristic wastes) in a calendar month or any facility discharging any amount of acutely hazardous wastes as specified in 40 CFR 261.30(d) and 261.33(e) is required to provide a one-time notification in writing to the County, EPA Regional Waste Management Division Manager, and the Southwest Regional Director of the Department of Ecology. Any existing user exempt from this notification shall comply with the requirements contained herein within 30 days of becoming aware of a discharge of 15 kilograms of hazardous wastes in a calendar month or the discharge of acutely hazardous wastes to the POTW.
Such notification shall include:
A. The name of the hazardous waste as set forth in 40 CFR Part 261;
B. The EPA Hazardous waste number; and
C. The type of discharge (continuous, batch, or other).
D. If an industrial user discharges more than 100 kilograms of such waste per calendar month to the POTW, 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 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.
These notification requirements do not apply to pollutants already reported under the self-monitoring requirements.
Whenever the EPA publishes final rules identifying additional hazardous wastes or new characteristics of hazardous waste, a user shall notify the County of the discharge of such a substance within 90 days of the effective date of such regulations.
