The rates of surcharges for BOD5 and SS shall be as follows:
SCBODi = $0.057 (BODi - 240) × Qi × 8.34
SCSSi = $0.134 (Ssi - 240) × Qi × 8.34
SCi = SCBODi + SCSSi
Where:
Qi = Total monthly flow volume expressed in million gallons
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 240 mg/l ($0.42 per pound over 240 mg/l)
SCSSi = Monthly surcharge in dollars for suspended solids for waste concentrations greater than 240 mg/l ($0.048 per pound over 240 mg/l)
SCi = Total monthly surcharge in dollars
