Findings 14 findings

F1 Page 12
The City of Redding Wastewater Treatment facilities are financially self-supporting.
F2 Page 12
Both plants were clean and relatively odor free.
F3 Page 12
Staff was friendly, cooperative and knowledgeable.
F4 Page 12
In accordance with Resolution 68-16 the State Water Resource Control Board will cite the City if it uses blending under non-emergency conditions. 12
F5 Page 13
Several engineers stated that if it came down to blending effluent or dumping raw sewage during high inflow, both of which could result in a fine, the City would elect to blend.
F6 Page 13
Employees stated that additional filtration capacity would alleviate the need for blending; however, additional filtration was removed from the original facility plan due to cost.
F7 Page 13
At this writing, the project plan is being modified to include additional filtration which should eliminate the need to blend.
F8 Page 13
The City failed to secure the Board’s written approval for the blending process in the initial design.
F9 Page 13
The City has no staff engineers that are expert in wastewater treatment technology. Consequently, it has no in-house capability to fully evaluate the merits of engineering designs.
F10 Page 13
Construction oversight was assigned to a division of the company that performed the engineering design. This created at least an appearance of a conflict of interest.
F11 Page 13
The City has a program to repair collection mains to reduce inflow and infiltration, but none to address faulty or improperly plumbed laterals. Implementing a program would reduce the problem caused by rain and groundwater.
F12 Page 13
The macerators (grinders) installed within the last two years require excessive maintenance. The manufacturer’s warranty has expired; however, the firm is re-engineering the unit at no cost to the City, at least this time.
F13 Page 13
There is a comprehensive procedures manual which includes operational data forms that are not being utilized. However, required information is gathered and recorded, utilizing locally generated forms.
F14 Page 13
The Clear Creek plant emits a significant amount of methane gas which is flared (burned) on site.
