(a) In addition to user charges based solely on quantity, nonresidential users shall also be subject to a strength surcharge in accordance with § 43-1.8(i). A monitoring program shall be initiated by the department to periodically measure the strength characteristics of wastewater discharges from these users, in accordance with § 43-1.8(k).
(b) The nonresidential user charge schedule applies to domestic strength wastewater having an average suspended solids loading of 200 mg/L. The charge to a nonresidential user whose wastewater loading exceeds 200 mg/L shall be determined by means of the following formula, where SSm equals the measured suspended solids loading for that user and c is the user’s charge per 1,000 gallons of either water usage or wastewater discharge, whichever applies.
(c) All nonresidential users that discharge wastewater having suspended solids loadings greater than 200 mg/L shall be identified by the department and shall be subject to this strength surcharge, effective upon the completion of construction of Phase II, Sand Island sewage treatment plant.
(d) Strength surcharges for BOD5 shall not be levied against nonresidential users until completion of the west and east Mamala Bay secondary treatment facilities, as applicable.
(e) The actual formulas for water usage and wastewater discharge are shown in the sewer service charge schedules listed separately in Appendix 43-A.
