The IU shall notify: the Director of Public Works; the Director of the Regional Waste Management Division of the United States Environmental Protection Agency; and the Director of the Solid and Hazardous Waste Management Administration of the Maryland Department of the Environment, in writing, of any discharge into the POTW of a substance, which, if otherwise disposed, would be a hazardous waste under 40 CFR Part 261. City Code, 1976/83, art. 25, §7(c)(1)(1st sen.) Ord. 91-775

Such notification shall include: the identity of the waste as set forth in 40 CFR Part 261; the EPA hazardous waste number; the type of discharge (batch, continuous or other); and if the IU discharges more than 220 pounds (100 kilograms) of such waste per calendar month to the POTW, the notification shall also contain the following information, to the extent each information is known and readily available to the user:an identification of the hazardous constituents contained in the wastes; an estimation of the mass and concentration of such constituents in the wastestream discharged during the calendar month; and an estimation of the mass of constituents in the wastestream expected to be discharged during the following 12 months. City Code, 1976/83, art. 25, §7(c)(1)(2nd sen.), (2) Ord. 91-775

Users who commence discharge after August 23, 1990, shall provide the notification no later than 180 days after the discharge of the listed or characteristic hazardous waste. Any notification under this subtitle needs to be submitted only once for each hazardous waste discharged. However, notification of changed discharges must be submitted in accordance with 40 CFR 403.12(j). City Code, 1976/83, art. 25, §7(c)(3), (4) Ord. 91-775

In the event of new regulations under § 3001 of the Resource Conservation Recovery Act identifying additional characteristics of hazardous wastes or listing any additional substance as a hazardous waste, the user must notify the individuals listed in § 6-1 above, or their authorized representatives, of the discharge of such substance(s) within 90 days of the effective date of such regulation. City Code, 1976/83, art. 25, §7(c)(7) Ord. 91-775

In the case of any notification made under this subtitle, the user must certify that a program has been implemented to reduce the volume and toxicity of hazardous waste generated, to the degree it has been determined to be economically practical. City Code, 1976/83, art. 25, §7(c)(8) Ord. 91-775

This notification does not apply to pollutants already reported under self-monitoring requirements of 40 CFR 403.12(b), (d), and (e). Users are exempt from the requirements of this subtitle during a calendar month in which they discharge no more than 33 pounds (15 kg) of hazardous wastes, unless the wastes are acute hazardous waste as specified in 40 CFR 261.30(d) and 261.33(e). Discharge of more than 33 pounds (15 kg) of non-acute hazardous waste in a calendar month, or of any quantity of acute hazardous wastes as specified in 40 CFR 261.30(d) and 261.33(e), requires a 1-time notification. Subsequent months during which a user discharges more than such quantities of any hazardous waste do not require additional notification. City Code, 1976/83, art. 25, §7(c)(5), (6) Ord. 91-775
