The city reserves the right to enter into special agreements with users, setting out special terms under which they may discharge into the system. In no case will a special agreement waive compliance with a pretreatment standard or requirement. However, the user may request a net gross adjustment to a categorical standard in accordance with 40 CFR Part 403.15. The user may also request a variance from the categorical pretreatment standard from the approval authority. Such a request will be approved only if the user can prove that factors relating to its discharge are fundamentally different from the factors considered by EPA when establishing that categorical pretreatment standard. A user requesting a fundamentally different factor variance must comply with the procedural and substantive provisions in 40 CFR Part 403.13.
