These manholes shall have a minimum twenty-four-inch diameter opening with cast-iron manhole cover or lockable lid. These sampling manholes shall be located at least 15 feet downstream of any bends, junctions or manholes. Maximum slope of upstream pipe shall be 2%.

B. All manholes shall be installed with flow measuring devices, such as a Parshall flume, Palmer Bowlus flume, subsonic flume or other suitable device as approved by the approving authority. An integral staff gauge shall be provided with each unit with measurements in hundredths of a foot. Flume size and type depends on flow rates anticipated and accuracy desired.

C. A flow metering device shall be provided. The metering device shall be a bubbler, ultrasonic or subsonic device as approved by the approving authority. Flow shall be indicated, totalized and recorded. A 4-20 mA signal or pulse proportional to flow shall be outputted to a sampler for flow proportional sampling.

D. A refrigerated flow proportional sampler shall be furnished, suitable for composite or hourly sampling (twenty-four-hour intervals).

E. Plans for the aforementioned facilities shall be prepared by a licensed professional engineer.

F. Plans, specifications and hydraulic calculations shall be submitted to the approving authority.

G. Control manholes, access facilities and related equipment shall be installed by the person discharging the waste, at his or her expense, and shall be maintained by him or her so as to be in safe condition, accessible and in proper operating condition at all times.

§ 150-38. Hazardous waste notification.

A. Any industrial user, except as specified in Subsection E below, which discharges to the POTW any substance which, if otherwise disposed of, would be a listed or characteristic hazardous waste under 40 CFR part 261, shall notify the POTW, in writing, of such discharge.

B. All hazardous waste notifications shall include:

(1) The name of the hazardous waste as set forth in 40 CFR part 261.

(2) The EPA hazardous waste number.

(3) The type of discharge (continuous, batch or other).

(4) A certification that the user 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.

C. In addition to the information submitted in Subsection B above, industrial users discharging more than 100 kilograms of hazardous waste per calendar month to the POTW shall obtain to the extent such information is known and readily available to the industrial user:

(1) An identification of the hazardous constituents contained in the waste.

(2) An estimation of the mass and concentration of such constituents in the waste stream discharged during that calendar month.

(3) An estimation of the mass of constituents in the waste stream expected to be discharged during the following 12 months.

D. Any notification under this provision need be submitted only once for each hazardous waste discharged, although notifications of changed discharges must be submitted in accordance of this chapter.

E. Industrial users are exempt from the hazardous waste notification requirement during a calendar month in which they discharge 15 kilograms or less of nonacute hazardous wastes. Discharge of any quantity of acute hazardous waste as specified in 40 CFR 261.30(d) and 261.33(e) requires a one-time notification.

§ 150-39. Measurement of flow.

The volume of flow used for computing sewer service charges shall be the metered water consumption of the person as shown in the records of meter readings maintained by the Water Department or Utility, except as noted in § 150-40.

§ 150-40. Metering of waste.

Devices for measuring the volume of waste discharged may be required by the approving authority if this volume cannot otherwise be determined from the metered water consumption records. Metering devices for determining the volume of waste shall be installed, owned and maintained by the person discharging the wastewater. Following approval and installation, such meters may not be removed without the consent of the approving authority.

§ 150-41. Waste sampling.

A. Industrial wastes discharged into the public sewers shall be subject to periodic inspection and a determination of character and concentration of said wastes.

B. The determination shall be made by the industry as often as may be deemed necessary by the approving authority.
