NOE - Notice of Exemption
Document Description
Emergency cleaning by City forces of a 43-year old sewer line for a distance of approximately 20,430 feet. Severe grease buildup, heavy root infiltration, cracks, sagging pipe sections, and rocks have been noted via recent televising of this line. Sewer overflows have been reported along this line on 2/15/2000, 9/21/2000, 3/5/2001, 5/21/2001, and 8/21/2001. The pipe size varies from 8 to 18 inches in diameter and is made of vitrified clay and PVC. Construction will be needed in this canyon to approximately 104 manholes. Access to additional manholes may be required during emergency cleaning. These construction activities include grading, repair of maintenance access, and installation of water crossings, if needed. Once this is completed, other side canyon areas may need to be accessed and sewer lines cleaned depending upon the results of further inspections. All work will be coordinated with the community and be monitored by a biologist.

Reasons for Exemption
This 43-year old sewer pipeline shows evidence of severe grease, cracks, heavy root intrusion, and debris and rocks in the line. Several seweroverflows have been noted in 2000 and 2001. The average daily flow is approximatel 0.52 million gallons per day (mgd) and the peak flow, 0.92 mgd. In the event of a sewer overflow, a significant amount of sewage can reach Lake Murray, Alvarado Creek, the San Diego River, the pacific Ocean, threatening wildlife habitat and public health and safety. Emergency cleaning is needed to prevent imminent spills and to avert further spills.
