Reasons for Exemption
The sewer mains in Chocolate Canyon range are approximately 72 to 77 years old and are in need of repair. The mains have been impacted by severe root intrusion, mineral and debris deposition, and substantial erosion of cracking of pipeline walls which have compromised the integrity of several sewer pipeline segments and manholes. Emergency cleaning personnel have captured pieces of broken pipe and debris during cleaning operations. Average daily flow through these pipelines is approximately 0.11 million gallons per day (mgd), with peak flows up to 0.26 mgd. In the event of a sewer spill, a significant amount of raw sewage could reach public waters at Chollas Creek and San Diego Bay, threatening wildlife habitat and public health and safety.
