15.64.020 Estimated industrial surcharge for strength group.
A. The city shall classify minor user establishments as commercial customers. Commercial customers shall be assessed a variable user charge in accordance with the wastewater user charge in $/HCF for "Non-Residential" as specified in the most current city of Petaluma wastewater service rate schedule based on the strength of the wastewater: low, medium, or high.
B. If an establishment contains operations from more than one of the strength groups, and the city determines that the surcharge rate for a particular strength group would not adequately compensate the city for its cost of treatment, the city may:
1. Assess a surcharge rate based on a proportional average of the strength group rates involved.
2. Require the establishment to be billed for an industrial surcharge computed under Section 15.64.010.
C. The owner or agent of the owner of an establishment classified into a strength group may elect to have the permitted industrial user surcharge billed directly under Section 15.64.010 rather than under this section by making application to the city, receiving the city’s approval and paying the required sampling costs.
