RICHMOND WWTP AND COLLECTION SYSTEM MONTHLY OPERATING REPORT OCTOBER 2013 EXECUTIVE SUMMARY General • Back up Dystor cover installation is progressing well. The parts and materials began arriving in late October and installation is expected to be complete by the middle of November. • A capital project to replace aging and deteriorating bulk chemical (sodium hypochlorite) storage tankage is being developed and will be proposed to the City. This is an important safety project with a Task Authorization (TA) expected to be submitted in November. • The treatment plant remains in need of capital improvements for both the grit removal system and electrical infrastructure (among other processes). Cost estimates and task authorizations have been developed and submitted to the City for these projects. Funding needs to be identified and the projects remain critical wastewater treatment reliability concerns. • A project proposal to clean the treatment plant’s grit channels and influent wet well is being developed by Synagro and will be presented to the City. • The US Peroxide H2S/Odor/Corrosion Reduction Pilot Study has been approved and we are moving forward with the installation of chemical feed skids (for hydrogen peroxide feed) and other project components. Start-up should occur during the third week of November. WWTP Operations • There was a single NPDES permit violation during the month; the issue was a residual effluent chlorine exceedance on October 15th caused by a failure of the # 3 water system which resulted in a violation of the permit. • There were no blending events during the month. • The monthly bioassay passed with 100% survival of the fathead minnows. • 2 phoned in Odor complaints were received during October. The locations of the calls were from a single address. Investigation found that the odor was suspected coming from a rental Veolia Water North America 601 Canal Blvd., Richmond, California 94804 Tel: 510-412-2001 Fax: 510-235-3354 www.veoliawaterna.com Portable Toilet that needed cleaning and possibly from an adjacent animal enclosure. An investigation and follow up with the resident were completed. • A summary table of the 12 H2S alerts follows; the highest level of H2S measured was 85 PPB peak on October 5th and the remaining peaks were 69 PPB or below. Plant investigations following up the alerts did not link the H2S to the treatment plant or otherwise determine their cause however it was noted that high heat and low winds occurred during the month.

Expect resolution in mid-November. We are able to run in a bypass situation if needed to balance influent flows. • New fiberglass safety grating has been installed in various locations in the facility, more grating has been ordered to continue replacement. • Plant Maintenance Department installed back-up pumping system for sludge transportation. Only a few small items left to complete this task. • Carollo Engineering is working with the Facility to design a Crossover Piping System between Digesters #1 and #2 to allow for more retention time of solids before transport. Collections Sanitary System Activities • We achieved our longest period without an SSO of 89 days. In late October we had 2 SSOs that were mainline blockages, both discharged into homes. One was caused by two massive sycamore trees on W. Richmond Ave; the roots from those trees caused the blockage that emitted SSO into basements on that street. The second SSO was found that there is a 350’ section of pipe that downsizes to 4” from 6” before upsizing back up to 6”. • Year to date there have been 23 SSOs where the Baykeeper Agreement imposes a limit of 33 SSOs • All the sewer lines in the NE quadrant have been cleaned with the exception of the easement lines which were root foamed in July. Those easement lines will be the focus of cleaning in November. • Veolia Richmond is moving forward with expanding the City’s Smartcover remote sewer monitoring network. Five additional Smartcover monitors will be installed at various hot spots (frequent sewer blockages) and known areas in the system where surcharging occurs during heavy wet weather events. • Courtesy clean-up by collections crews were done for each of 6 private lateral service calls. Each homeowner was given a lateral notice. • We have designated an employee to inspect prior SSO manholes and hotspot lines one day a week. For the month of October he observed 9 surcharged manholes that were then cleared 3 by cleaning crews. This performance measure kept the 9 surcharged manholes from becoming SSOs. • There were 21 service calls that Veolia responded to 6 calls were caused by private lateral issues, which Veolia provided courtesy cleaning. • We have a major reduction on plant inflow since we did a repair on 500 Ohio Street. Approximately 1mgd is what we are less treating. • We reviewed with all staff the new regulations concerning the reporting of SSO by category.

We reported this information to the City with a proposal for repair. • Held meeting between City and Veolia staff and Management led by Chad Davisson to discuss how to improve the communication process of the group as a whole. • Staff ordered 16 storm grates from Albany Steels and it is in the process of our accounting department issuing a PO. Installed 5 remaining storm grates in Birmingham Dr/Groom Dr area. • Completed about 80% of the CCTV project planned for the month of October. 20% is inaccessible for various reasons. 4 Storm Calls 7 Point Repairs 0 Manhole Repairs 0 Manhole Inspections 75 CCTV (ft) 1,310 GPS Surveys 0 Storm Pipe Cleaning (ft) 160 Storm General Maintenance Cleaning 32 (V-Ditches, Catch Basins, Culverts, Storm Pump Stations) Gizzard (trash capture device) 1 Cleaning/Inspections Flap Gate/Duck Bill Inspections 0 Lift Station PMs 99 Capital Improvement Program • No Updates 5 VEOLIA WATER SANITARY PIPE CLEANING, OCTOBER 2013 PIPE DATE CLEANED UPSTREAM DOWNSTREAM LOCATION LENGTH DEBRIS 1 DEBRIS 2 DEBRIS 3 10/31/2013 G12MH1016 G12MH209 BECK ST 243 GREASE GRIT 10/31/2013 F12MH201 F12MH2022 POTRERO 402 H GRE GREASE ROOTS 10/31/2013 F12MH826 F12MH827 750 CARLSON BLVD 240 H GRE GRIT 10/31/2013 F12SF254 F12MH825 750 CARLSON BLVD 206 H GRE GRIT 10/31/2013 E14MH1970 E14MH2799 5526 ALAMEDA AVE 496 GREASE GRIT ROOTS 10/31/2013 E14MH2750 E14MH1970 5812 ALAMEDA AVE 699 GREASE GRIT ROOTS 10/30/2013 F11MH1234 F11MH1235 686 30TH S ST 244 GREASE GRIT 10/30/2013 F11MH1233 F11MH1234 690 31ST S ST 301 GREASE GRIT 10/30/2013 F12MH1232 F11MH1233 717 32ND S ST 276 GREASE GRIT 10/30/2013 G7MH340 G7MH341 SANTA FE 148 H ROOT 10/30/2013 F12MH816 F12MH1232 722 33RD S ST 249 GREASE GRIT 10/30/2013 E14MH1971 E14MH2747 5843 BAYVIEW AVE 682 GREASE GRIT 10/30/2013 G7MH341 G7MH340 SANTA FE 127 H ROOT 10/30/2013 H12MH2784 H12MH1037 100 37TH STREET 338 H GRE H GRIT 10/30/2013 H12MH2784 H12MH1037 100 37TH STREET 338 H GRE H ROOTS 10/30/2013 G7SF997 G7MH660 W.RICHMOND 133 ROOTS 10/29/2013 H12MH2784 H12MH1037 100 37TH ST 338 H GRE H ROOTS GRIT 10/29/2013 G11MH1210 G11MH1212 123 31ST S ST 470 GREASE GRIT 10/29/2013 I13SF75 H13MH623 4330 ROOSEVELT AVE 481 10/29/2013
