A. The City may enter into special agreements with users to authorize discharges compatible with the POTW at concentrations greater than those typical of domestic wastewater. Users with BOD or TSS levels higher than three hundred (300) mg/L or FOG higher than two hundred (200) mg/L must have such an agreement before commencing discharge. Within such agreements, the City may establish terms of the user’s discharge to the POTW including maximum flow rates and concentrations. The City may also establish fees to recover costs associated with treating such wastes and monitoring schedules in such agreements. In no case will a special agreement waive compliance with State or Federal pretreatment standards or requirements including Categorical Standards.

B. Users discharging or intending to discharge pollutants other than BOD and TSS in a significant amount and claiming compatibility must prove, to the satisfaction of the City, that such pollutants are compatible with the POTW. The City may require any claim of compatibility to be approved by the DOE in writing.

C. The City reserves the right to enter into special agreements with users that the City feels may be a minor user, SIU, middle tier SIU, nonsignificant SIU or zero discharge SIU setting out different terms under which a user may discharge. The user may request a net/gross adjustment to a Categorical Standard, in accordance with 40 CFR 403.15; they may also request a variance from the Categorical Pretreatment Standard from the DOE in accordance with 40 CFR 403.13.
