Reasons for Exemption
This 48 year old trunk sewer line has not been accessed for cleaning and maintenance for many years. In addition, recent inspection has shown: deteriorated, broken, and sagging pipelines; heavy root intrusion; displaced joints; multiple cracks; and signigicant sludge buildup in many sections of the line. Due to these reasons there is a high potential for sewage spills. The average daily flow is approx. 0.16 million gallons per day (mgd) and the peak flow is a high as 0.37 mgd. Therefore, in the event of a sewage spill, a signigicant amount of flow would reach Mission Bay (public waters) jeopardizing public health and safety.
