(iv) Operation and Maintenance Program. The SSMP must include those elements listed below that are appropriate and applicable to the Enrollee's system: (a) Maintain an up-to-date map of the sanitary sewer system, showing all gravity line segments and manholes, pumping facilities, pressure pipes and valves, and applicable stormwater conveyance facilities. The City has a Sewer Atlas that shows the location of all sewer mains, manholes and pumping stations. The City does not have any pressure pipelines in the sewer system. The Atlas also has reference numbers to the particular construction plans that were used to build each portion of the system. The map is created and maintained by the Water Engineering Section. Currently, a Senior Civil Engineer and two Assistant Engineers are responsible for creating and updating all of the sewer maps and related databases. The Senior Civil Engineer also oversees the sewer video inspection program, as well as the sewer main condition assessments. The Senior Civil Engineer reports directly to the FOG Control Program Manager. The City has completed the conversion of all 186 manually drafted map sheets into a digital sewer atlas. The locations of all the storm water conveyance facilities are shown on separate maps prepared by the Public Works Agency Design Division. City sewer maintenance staff members recognize the link between a sewer spill and its travel in a storm drain facility to the receiving waters. The City educates its staff to understand the storm drain network and capture a spill before it has entered the storm drain system. 75A-10
