§ 53.056. ADMISSION OF INDUSTRIAL AND COMMERCIAL WASTE.

All users of the sanitary sewers shall recognize and comply with the following:

(A)

The economy and desirability of the combined treatment of industrial and commercial wastes and sanitary sewage is recognized. However, not all types and quantities of industrial and commercial wastes can be so treated. It shall be the City's policy to admit the types and quantities of industrial and commercial wastes that are not harmful or damaging to the structures, processes or operation of the sewage works or are not specifically prohibited. In all cases, a special permit will be issued which will state specific conditions and requirements to be maintained. It is also recognized that to provide this service, additional facilities or treatment are required. The cost of which must be borne by the user receiving the benefits.

(B)

(1)

Approval in advance by the City is required for the anticipated admission into the public sewers of industrial or commercial wastes where the surcharge limits will be exceeded for the following:

CBOD;

COD;

Suspended Solids;

Oil/Grease Content.

(2)

The user shall provide chemical analyses of the discharge according to a schedule to be established by the City and continued discharge shall be subject to approval of the City.

(C)

Samples shall be collected so as to be a representative sample of the actual quality of the wastes. Samples for analysis may be collected by the user or his representative. Analysis shall be made by a registered sanitary engineer or graduate chemist whose qualifications are acceptable to the City or a wastewater treatment plant operator licensed and registered in the State, or a water testing laboratory certified by the State, using the laboratory methods for the examination of wastewater as set forth in 40 CFR 136.

(D)

When required by the Director, any establishment discharging industrial or commercial wastes into the sewer system shall construct and maintain at its sole expense a suitable control manhole or other suitable control station downstream from any treatment, storage, or other approved works to facilitate observation, measurement and sampling of all wastes including all domestic sewage from the establishment. The location and methods of construction of the control station shall be approved by the Director. The control station shall be maintained by the establishment so as to be safe and accessible at all times. If any establishment wishes to meter its waste discharge into the sewer system to verify in-product water retention or other uses of metered flow, they may, at their sole expense, install a flow-metering device as approved by the Director. The control station shall be accessible to City personnel at all times for sampling. When required, construction of those facilities shall be completed within ninety (90) days following written notification by the City.
