Recommendation for Council action: NOTE and FILE the May 8, 2006 Bureau of Sanitation (BOS) report and supplemental materials submitted in Committee on June 21, 2006 relative to sewer odor control, inasmuch as this report and supplemental materials are _for information only and no Council action is required. Fiscal Impact Statement: Not applicable Summary: At its regular June 21, 2006 meeting, your Committee considered a May 8, 2006 BOS report and supplemental materials submitted in Committee relative to sewer odor control. According to the BOS, all sewers generate a rotten egg-odor caused by hydrogen sulfide which is produced by bacteria in the sewage. Significant amounts of hydrogen sulfide gas are produced where sewers bend, change slope, construct, and pass through junction and drop structures. This gas can escape from the sewer system through maintenance holes and sewer laterals in areas with high sewer gas pressure. The pressure usually increased as the sewer levels rise each day. Large sewers with high flows are particularly susceptible to odor problems caused by the release of hydrogen sulfide gas. The BOS then provided an overview of its policies for the investigating and responding to sewer odor complaints and stated that wherever possible, the BOS will take corrective action. In complicated problems are referred to engineers who review the field investigations and sewer design and perform field tests to develop plans to reduce or eliminate the odors. The BOS also provided an overview of its maintenance program for minimizing sewer odors. Finally, the BOS stated that in 2001, extensive monitoring and testing was done to pinpoint the high sewer pressure areas in large sewers located near La Cienega Boulevard, Jefferson Boulevard and Rodeo Road. Three Air Treatment Facilities (ATFs) were planned and will begin construction to discharge treated sewer gas pressure. Interim carbon scrubbers are being used at these locations until the ATFs are completed. Additional ATFs are also planned for four locations on the recently completed ECIS and NEIS sewers in anticipation of higher sewer gas pressure (a map detailing the locations of the proposed ATFs is attached to the Council file). After further consideration and having provided an opportunity for public comment, the Committee moved to note and file the May 8, 2006 Bureau of Sanitation (BOS) report and supplemental materials submitted in Committee on June 21, 2006 relative to sewer odor control, inasmuch as this report and supplemental materials are for information only and no Council action is required. This matter is now forwarded to the Council for its consideration.
