1 Technical Director s Report June 2, 212 Plant Loading and Operations Summary May 212 Biochemical Oxygen Demand, 5-Day (Avg. 37,5 lb./day) Total Suspended Solids (Avg. 81,8 lb./day) Average Daily Flow (25.1 million gallons/day) Maximum Daily Flow (34.1 million gallons/day) 55 percent of design 74 percent of design 61 percent of design 27 percent of design Permit Limits (avg./max.) Reported Values Violations CBOD 5, mg/l 2/4 2/3 TSS, mg/l 25/45 7/8 NH 3 -N, mg/l 1.5/3. <.48/2.16 Fecal coliform per 1 ml 4* 29 Chlorine Residual, mg/l.5* <.5 Dissolved Oxygen, mg/l 6. (minimum) 6.2 *Effluent disinfection is required May 1 through October 31. No violations of NPDES permit limits occurred in May. The total amount of stabilized sludge sent to storage at the Wyckles Road Land Application Facility in May was 819 tons. Waste sludge totaling 168 tons was destroyed using the anaerobic digester stabilization process. Methane utilized to generate electricity saved the District an estimated $672 for the month in electrical costs. Activities District staff met with Tate & Lyle on May 11 and with Tate & Lyle and Amyris representatives on June 4 to discuss financing for the receiving station construction. Discussions are ongoing. The District s nickel consultant provided a report to be used as an attachment for the site-specific water quality standard petition. We expect to file the petition with the Pollution Control Board before the end of June. We are continuing to discuss options for recovering the value of our digester gas with representatives of Golden Energy Services, Inc. Golden has provided a proposal outlining options for partnering with them on this project. Donohue and Associates are proceeding with design work for the digester mixer project. Final plans are scheduled to be produced around the end of July. J & B Waste, contractor for the South Sludge Lagoons dewatering project, began work for the year in early May and dredging is proceeding quickly. Around half of the sludge has been removed from Lagoon 8.

3 SANITARY DISTRICT OF DECATUR 51 DIPPER LANE, DECATUR, IL MEMORANDUM TO: Tim Kluge DATE: 6/1/12 FROM: Larry Arnold SUBJECT: Laboratory activities for May 212 Routine : Monitoring of treatment plant, industrial users, and receiving stream samples for compliance purposes and process monitoring continued. Sampling and analysis of influent, effluent, and sludge for quarterly and annual NPDES requirements was conducted. Laboratory personnel continued monitoring H2S and other odor causing chemicals within the covered areas of the activated carbon treatment units. Laboratory personnel continued to perform additional ammonia and nitrate analysis to monitor the effect of changes made by ADM in their wastewater treatment to help prevent the floating solids problem here at the plant. Analysis was continued to confirm water quality of plant groundwater and groundwater near the 7 th Ward CSO facility in conjunction with the district s dissolved solids strategy. Chloride analysis of industrial users continued in support of this strategy, as well. Safety meetings have continued and there was no first report of injury in the laboratory during this period. Non-Routine : 1) The laboratory continues to investigate the potential role of amounts of incoming Total Kjeldahl Nitrogen (Ammonia plus forms of Organic Nitrogen) in affecting the plant s nitrification ability. Incoming Total Kjeldahl Nitrogen concentrations during the month of April were generally under our plant s loading capacity for it. We did observe higher than normal NH3-N levels in the plant effluent during the month which did not seem to be attributable to TKN loadings. 2) The laboratory continued additional analyses of the supernatant returned from Wyckle s sludge lagoons. This study was at the request of Black and Veatch and is related to the reclaimed water study and potential future EPA plant performance requirements. This will also be of significance in determination of return plant loadings via sludge lagoon supernatant generated by the Tate and Lyle/Amyris project which commenced in November. The number of analytes evaluated were increased in February to include anions and metals for comparison with pre-amyris discharge results obtained for the supernatant for these parameters last year. 3) Work continued on a laboratory manager position standard operating procedure. A generic calendar was setup indicating at what time of year certain actions need to be taken in relation to infrequent events and also indicates primary daily activities. This effort is related to transition planning for the laboratory.

4 4) Laboratory management began a periodic review of existing laboratory procedures. During this review process, we completed linking job safety analysis data with the laboratory procedures and setting access for all laboratory personnel to these documents on the district intranet. The US EPA laboratory methods update includes other new requirements that will have to be interfaced in upon federal register publication which is now scheduled for mid June 212. Laboratory management is reviewing these updates and determining what additional quality control requirements will have to be added to analyses done for Clean Water Act (CWA) purposes. We are also used this opportunity to compile potential test questions for a laboratory position classification system testing program. This program will be used in conjunction with performance and longevity to yield a career path for laboratory personnel similar to that used in other laboratories and to that used by the district s operations and maintenance departments. Results towards this effort to date have been forwarded to upper management at the district. 5) Work was completed on the 212 US EPA DMR-QA performance evaluation samples. All data is due to be reported by July 6, 212 and has already been entered in the performance evaluation sample vendor s E-data system. 6) Laboratory management continued updating the district lab data handling manual as part of the transition effort. Pretreatment Activity during May 212 Verbal Notices We issued a Verbal Notice to Stripmasters Services, Inc. on May 16, 212 because they failed to submit three documents required by their discharge permit by the May 15, 212 due date. We issued a Verbal Notice to Akorn, Inc. on May 31, 212 because they discovered in their own self-monitoring that they discharged wastewater that exceeded their permit limit for acetone on May 9, 212. Warning Notices We did not issue any Warning Notices during May 212. Violation Notices We did not issue any Notice of Violations during May 212. Executive Orders We did not issue any Executive Orders during May 212. Penalty Assessment We did not assess any industrial penalties for May 212. General Activity 1. We monitored thirteen commercial and industrial users (IU) and we performed eleven industrial user inspections during May 212.

5 2. We continued to monitor the H2S level under the SDD headworks and PE channel covers during May We provided more samples to River Bend Labs for testing related to the ongoing ADM nickel reduction project. 4. I attended the NACWA Pretreatment and Pollution Prevention Workshop from May 9-11, We received permit applications from Bulkmatic Transport and Canadian National/Illinois Central Railroad during May because their existing permits are due to expire in August. 6. We sent wastewater hauler permit applications to Gulliford s Septic Service, St. Claire Services of Illinois, and Zeschke Septic Cleaning LLC during May because their existing permits are due to expire on July 21, 212. New permits are pending. 7. I met with representatives of Argenta s water plant during May in preparation of them discharging into our system. I determined that they would not be a significant industrial user.

6 SANITARY DISTRICT OF DECATUR 51 Dipper Lane Decatur, Illinois (217) I&C Shop Monthly Activity Report For March 212 Work Order Activity Completed 39 Corrective Work Orders Completed 153 PM Work Orders Completed 11 Safety Work Orders Completed 1 Project Work Order Completed 3 Process Work Orders Completed 2 Training Work Orders I&C Shop Projects I&C assisted in the startup of the Argenta pump station and assisted Bodine Electric with the Eastside Booster pump station; final programming and checkout will be done in June. SCADA has been upgraded, minor issues are still being corrected. Project is 95% complete. The new blowers are running and being monitored for any issues, data is being gathered to determine what will be needed for the control scheme program. The camera project is moving forward, as part of the project we have reconfigured the controls for the front gate to add SCADA control for Operations and a new Comcast business class modem for Plant internet access. Testing of the new modem is now underway, after a two week test we will switch over to the new system.
