Home My WebLink AboutMinutes - October 8, 2013 SSLODI CITY COUNCIL SHIRTSLEEVE SESSION CARNEGIE FORUM, 305 WEST PINE STREET TUESDAY, OCTOBER 8, 2013 A. Roll Call by City Clerk An Informal Informational Meeting ("Shirtsleeve" Session) of the Lodi City Council was held Tuesday, October 8, 2013, commencing at 7:02 a.m. Present: Council Member Hansen, Council Member Mounce, Mayor Pro Tempore Katzakian, and Mayor Nakanishi Absent: Council Member Johnson Also Present: City Manager Bartlam, City Attorney Schwabauer, and Assistant City Clerk Robison B. Topic(s) B-1 Status Report on White Slouah Water Pollution Control Facility Discharae Permit (PW) Deputy Public Works Director Larry Parlin provided a PowerPoint presentation regarding the report on the White Slough Water Pollution Control Facility discharge permit. Specific topics of discussion included background, permitting process, key requirements for Waste Discharge Requirements and Master Reclamation Permit, key requirements for the National Pollutant Discharge Elimination System Permit, financial impacts, looking forward, land application expansion study, and pretreatment program update. Mr. Parlin reported that the permits were adopted on October 3, 2013. In response to Council Member Hansen, Mr. Parlin explained that the City has two lengthy permit documents, many of the comments were editorial, and staff worked to ensure consistency in the permit on a region -wide basis so problems in other permits would not trickle down to the rest. In addition, the board had new permit writers who were unfamiliar with Lodi's history. In response to Council Member Hansen, Mr. Parlin stated that groundwater flow is a complex matter and more analysis is necessary to look at background locations, ensure the right wells are there, and to account for issues that might affect flow, such as weather, the Delta, and dairies. In response to Mayor Nakanishi, Mr. Parlin stated the City has two agricultural wells used by the farmers when they need extra water that have been at that location for a long while. In response to Council Member Hansen, Mr. Parlin stated the ponds affect groundwater and flows can change direction, but overall it is manageable. In response to Mayor Nakanishi, City Manager Bartlam stated the City sold approximately 25 acres in easements to Northern California Power Agency (NCPA) and out of 1,000 acres there is construction on roughly 100 acres. Mr. Parlin added that farmers are irrigating approximately 700 acres. In response to Mayor Pro Tempore Katzakian, Mr. Parlin stated two-thirds of the water is committed, leaving a third left for use. Mr. Bartlam stated the water use is seasonally adjusted as there are different needs in winter versus summer. The City typically discharges water in winter because farmers do not take any during those months. In response to Mayor Pro Tempore Katzakian, Mr. Parlin stated that, if it is feasible in the future, the City could store and use the water because flows will increase over time, while still retaining the ability to discharge water if necessary. In response to Mayor Pro Tempore Katzakian, Mr. Parlin stated the Lodi Energy Center is only using 20 percent of the contracted flow amount, which is 1,600 acre feet. Mr. Bartlam pointed out that the City transferred the lease from water based to land -rent based. Mr. Parlin further responded that future growth would not be a significant burden on the flow. In response to Council Member Hansen, Mr. Bartlam stated the City would discuss with NCPA the need for it to build additional storage for its own use. In response to Mayor Nakanishi, Mr. Parlin stated that San Diego is currently working on a project to discharge wastewater into a drinking water reservoir for use and there are similar pilot projects in Southern California and Florida. In response to Council Member Hansen, Mr. Bartlam stated the City owns the conveyance system and it predates the City's activity in that area. In response to Mayor Nakanishi, Mr. Bartlam stated the agricultural leases are worth $100,000 in revenue a year to the City and the Lodi Energy Center is approximately $100,000 a year. In further response, Mr. Parlin stated that the goal is to have full reclamation of water and the new permits are good for five years. In response to Mayor Pro Tempore Katzakian, Mr. Bartlam stated that new transmission lines is one in a series of alternatives, but a greater concern is the affect on groundwater. The ability to use the land for farming is a benefit that many do not have, however, the state could eventually over regulate the City's ability to continue do so. If it becomes too expensive to continue with groundwater, other options will need to be explored. Public Works Director Wally Sandelin stated the Lodi Energy Center stores Title 22 water and the supplemental filtration system and disinfection by the ultraviolet system are very expensive to operate, therefore water that does not go through the system saves the City on power and maintenance. Mr. Sandelin added that the gap in growth between 5.2 million gallons a day (mgd) to 8 mgd could take 30 to 50 years, so plant expansion would not be necessary for decades. In response to Council Member Hansen, Mr. Bartlam stated that, during the permit process, no comments were received from any non-governmental agency, including agencies committed to protecting the Delta, which is significant. In response to Mayor Pro Tempore Katzakian, Mr. Bartlam responded that approximately 60 cents on every dollar goes toward monitoring and testing, which is passed onto rate payers. C.
