The name of the hazardous waste as set forth in 40 CFR Part 261, <br /> B. The EPA Hazardous waste number; and <br /> C. The type of discharge (continuous,batch, or other). <br /> D. If an industrial user discharges more than 100 kilograms of such waste per <br /> calendar per month to the sewer system, the notification shall also contain the <br /> following information to the extent it is known or readily available to the <br /> industrial user: <br /> (1) an identification of the hazardous constituents contained in the wastes, <br /> (2) an estimation of the mass and concentration of such constituents in the <br /> wastestreams discharged during that calendar month, and <br /> (3) an estimation of the mass of constituents in the wastestreams expected to <br /> be discharged during the following 12 months. <br /> These notification requirements do not apply to pollutants already <br /> reported under the self-monitoring requirements. <br /> Whenever the EPA publishes final rules identifying additional hazardous <br /> wastes or new characteristics of hazardous waste, a user shall notify the <br /> City of the discharge of such a substance within 90 days of the effective <br /> date of such regulations. <br /> In the case of any notification made under this paragraph, an industrial user shall certify <br /> that it has a program in place to reduce the volume and toxicity of hazardous wastes <br /> 39 <br />
