§ 52.109. NOTIFICATION OF HAZARDOUS WASTE DISCHARGE.
Latest version.
(A) The industrial user shall notify the POTW, the EPA Regional Waste Management Division Director, and state hazardous waste authorities in writing of any discharge into the POTW of a substance which, if otherwise disposed of, would be a hazardous waste under 40 C.F.R. pt. 261. The notification must include the name of the hazardous waste as set forth in 40 C.F.R. pt. 261, the EPA hazardous waste number, and the type of discharge (continuous, batch, or other). If the industrial user discharges more than 100 kilograms of the waste per calendar month to the POTW, the notification shall also contain the following information to the extent the information is known and readily available to the industrial user: an identification of the hazardous constituents contained in the wastes, an estimation of the mass and concentration of the constituents in the wastestream discharged during that calendar month, and an estimation of the mass of constituents in the wastestream expected to be discharged during the following 12 months. All notifications must take place within 180 days of the effective date of this chapter. Industrial users who commence discharging after the effective date of this chapter shall provide the notification no later than 180 days after the discharge of the listed or characteristic hazardous waste. Any notification under this division (A) need be submitted only once for each hazardous waste discharged. However, notifications of changed discharges must be submitted under 40 C.F.R. pt. 403.12(j). The notification requirement in this section does not apply to pollutants already reported under the self-monitoring requirements of 40 C.F.R. pt. 403.12(b), (d), and (e).
(B) Dischargers are exempt from the requirements of division (A) above during a calendar month in which they may discharge no more than 15 kilograms of hazardous wastes, unless the wastes are acute hazardous wastes as specified in 40 C.F.R. pts. 261.30(d) and 261.33(e). Discharge of more than 15 kilograms of nonacute hazardous wastes in a calendar month, or of any quantity of acute hazardous wastes as specified in 40 C.F.R. pts. 261.30(d) and 261.33(e), requires a one-time notification. Subsequent months during which the industrial user discharges more than the quantities of any hazardous waste do not require additional notification.
(C) In the case of any new regulation under § 3001 of RCRA identifying additional characteristics of hazardous waste or listing any additional substance as a hazardous waste, the industrial user must notify the POTW, the EPA Regional Waste Management Waste Division Director, and state hazardous waste authorities of the discharge of the substance within 90 days of the effective date of the regulations.
(D) In the case of any notification made under this section, the industrial 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.
