(A) Rates. The rates of surcharges for BOD and SS shall be as follows.
per lb. of BOD5 | $1.14 |
per lb. of SS | $1.14 |
(B) Charge calculation. The surcharge for BOD5 and SS shall be calculated as follows.
SCBODi = 0.22 (BODi -204) x Qi x 8.34 SCSSi = 0.18 (SSi - 240) x Qi x 8.34 Sci = SCBODi + SCSSI |
Where: Qi = Total monthly flow volume expressed in million gallons per day BODi= Biochemical oxygen demand concentration (five-day, 20° C) of waste expressed in milligrams per liter SSi = Suspended solids concentration of waste expressed in milligrams per liter SCBODi = Monthly surcharge in dollars for biochemical oxygen demand for waste concentrations greater than 204 mg/l SCSSI = Monthly surcharge in dollars for suspended solids for waste concentrations greater than 240 mg Sci = Total monthly surcharge in dollars |
