§ 20-5-104. TREATMENT SURCHARGE.

(a)

Generally. In addition to the annual sewer service charge, there shall be charged a treatment surcharge for discharging any wastes into the system which exceed the maximum values of polluting materials established by the surcharge formula in subsection (b) of this section. Such treatment surcharge shall be applicable to all users that discharge directly or indirectly into the system and shall be payable to the county annually.

(b)

Computation of treatment surcharges.

(1)

Treatment surcharges will be based upon the volume and concentration of flow discharged to the system multiplied by factors expressing the cost for treating the constituents covered by the formula.

(2)

The amount of surcharge will be determined by the following formula:

Total treatment surcharge =

V x 8.34 x FA(BOD - 300) + V x 8.34 x FB(TSS - 300);

where:

V = Volume of waste in millions of gallons discharged to the system, such to be expressed to the nearest thousand gallons;

FA = Cost per pound (in dollars) of removing BOD constituents from the sewage, such to be expressed to the nearest tenth of a cent as determined by the Engineer, subject to approval by the County Executive;

FB = Cost per pound (in dollars) of removing suspended solids from the sewage, such to be expressed to the nearest tenth of a cent as determined by the Engineer, subject to the approval by the County Executive.

(3)

A maximum of three hundred (300) mg/l by weight of BOD and TSS are allowable without payment of surcharge.

(4)

Should it become necessary to place a surcharge on other constituents, charges will be computed in the same manner.

(5)

Until a cost can be established for the treatment of each constituent at treatment plants operated by the county or Baltimore City, the cost factor may be based upon the average cost of treating those constituents at other plants having like or similar processes and effluent requirements.
