RECOMMENDATION Staff recommends adoption of the Ordinance on First Reading. At its February 23, 2006 meeting, the Water Board unanimously approved the modifications. EXECUTIVE SUMMARY The proposed modifications pertain to the following wastewater industrial discharge provisions of the City Code: • Section 26-206 Definitions Grab Sample—As directed by the EPA,the definition will be updated to be consistent with the EPA definition. This modification will be more restrictive as a time limitation will be specified where one did not previously exist. Zero-Discharge - A definition of zero-discharge permit will be added to Code. RV Wastewater- A definition of RV wastewater will be added to Code. • Section 26-318 Sampling and analysis As recommended by the EPA, the required period of records retention for industrial pretreatment will be changed from three to five years. • Section 26-343 Discharge limitations Language will be added to provide the General Manager with authority to request records from dental practices and obsolete language concerning date of mercury program initiation will also be deleted. This modification does not increase requirements on dental offices but does clarify the General Manager's authority. • Sections 26-308 and 26-309 The Code will be modified to state that, when applicable, a zero-discharge permit may be issued as the result of an industrial discharge permit application. The modification does not increase or relax existing permit application requirements. May 1, 2007 -2- Item No. 14 The United States Environmental Protection Agency(EPA)has given approval for the modifications and completed a thirty day public notification process for them. BACKGROUND Section 26-206 Definitions: Grab Sample—As directed by the EPA, the definition has been updated to be consistent with the EPA definition. The EPA definition specifies a time limitation of fifteen(15) minutes or less for collection of a grab sample. This time limitation will be added in the proposed modification. The definition currently in City Code does not specify a time limitation. Language will also be added clarifying that a grab sample is an individual sample. This modification will be more restrictive as a time limitation will be specified where one did not previously exist. Zero-Discharge-A definition of zero-discharge permit has been added to Code and language added to the Pretreatment definition to include zero-discharge as a potential pretreatment or treatment requirement. The legal authority to issue a permit prohibiting any discharge from a particular industrial process will enable the City to verify and enforce zero-discharge requirements when applicable. A zero-discharge permit would be appropriate in a situation where an industry elects to recycle process wastewater or has the wastewater taken offsite for treatment instead of discharging the wastewater to the sanitary sewer. In certain situations the City could find it necessary to require zero-discharge of a toxic process waste. This modification will provide a mechanism to regulate these types of industrial wastewater. It will provide a more direct means to address these types of wastewater but will not result in existing policy becoming more or less restrictive. RV Wastewater - The City was directed by EPA in December 2004 to regulate commercial RV wastewater dump sites. The City began issuing discharge permits to RV dump sites in 2005. Existing City Code does not provide a definition of RV wastewater. This modification will add a definition of RV wastewater. In order to avoid possible confusion,the septage waste definition will be modified to clarify that the City does not define RV wastewater to be septage waste. Section 26-308 Industrial discharge permit application and Section 26-309 Existing industrial discharge user discharge permit application In order to provide legal authority for issuing zero-discharge permits, the Code will be modified to state that, when applicable, a zero-discharge permit may be issued as the result of an industrial discharge permit application submitted from either a new or existing industrial user. A permit application is required when a new industrial discharge permit is issued or when an existing permit is renewed. This modification adds language that includes zero-discharge permits with the May 1, 2007 -3- Item No. 14 existing requirements for discharge permit application. The modification does not increase or relax existing permit application requirements. Section 26-318 Sampling and analysis The required period of records retention has been changed from three to five years in order to be in agreement with EPA biosolids records retention requirements. Section 26-343 Discharge limitations Modifications will be made to the code language regulating mercury discharge from dental offices. Obsolete language concerning date of program initiation has been deleted. Language will be added to allow disposal of dental amalgam waste as hazardous waste. Existing Code limits amalgam waste disposal to recycling of the waste. This modification relaxes requirements as it provides an additional means to dispose of waste amalgam. A modification will be added to provide the General Manager with authority to request records regarding installation and operation of equipment,or the purchase,use,storage,recycling or disposal of dental amalgam if the records are related to compliance enforcement of the dental mercury control program. This modification does not increase requirements on dental offices but does clarify the General Manager's authority to request records pertaining to existing requirements. ATTACHMENTS 1.

The Utilities uses these annual raw water rates and charges for the purpose of charging for various uses of its raw water. These uses include rental to agricultural users,meeting certain raw water delivery obligations and use by other City departments. Consistent with the last few years,staff is again proposing two separate categories for raw water rates and charges. The first category includes only those sources for which an active rental market exists. The second category includes sources with a limited rental market or which are used primarily to irrigate City facilities(parks,golf courses, etc.). The Board was provided with tables showing actual and proposed figures for assessments,rental rates, and delivery charges for the years 2003-2006. Dennis shared that the early snow pack is encouraging and that the City will continue to monitor its supply when making surplus raw water available for rental this year. The first priority will be to insure that adequate supplies will be carried over into 2007,although current projections indicate that the City will have ample surplus supplies available for rental this year. Board member John Bartholow made a motion, seconded by Reagan Waskom to recommend to City Council the staff's proposed raw water rental rates and delivery charges for the 2006 season. The motion passed unanimously. Q}nrnimagrAdmO ent Code C umm and Memiry Undate Ron Russell,Acting Technical Services Supervisor provided an overview of the wastewater code additions and modifications as follows: 1. Update grab sample definition -The definition will be revised to read: An individual sample which is taken from a waste stream on a one-time basis with no regard to the flow in the waste stream and over a period of time not to exceed fifteen(15)minutes. 2. Add definition of RV dump stations—RV wastewater shall mean domestic wastewater from a boat or recreational vehicle such as a camper, motor home or trailer used for traveling or recreational purposes. An addition to the septage waste definition will be made to clarify that RV waste is not septage waste. 3. Authority to issue Zero Discharge permits- Zero process discharge permits will be issued to industrial users who generate prohibited or high strength process wastewater, but discharge none of the process wastewater to the sanitary sewer. This type permit will enable the City to enforce and verify zero discharge conditions are in place at the permitted industry. 4. Change records retention requirement from 3 to 5 years. 5. Addition of an option to manage waste amalgam as a hazardous waste. Water Board Meeting Minutes February 23,2006 Page 3 Board member Reagan Waskom made a motion seconded by Board member Eileen Dornfest to approve the Code additions and modifications of the Wastewater Code with the added language to empower the General Manager to(request documentation from dentists as needed.
