ITEM #27 CITY OF COLTON AGENDA REPORT FOR THE CITY COUNCIL AND COLTON UTILITY AUTHORITY MEETING OFJUNE 5, 2007 TO: HONORABLE MAYOR AND MEMBERS OF THE CITY COUNCIL, HONORABLE CHAIRPERSON AND UTILITY AUTHORITY MEMBERS FROM: ERIC R. FRASER, DIRECTOR OF WATER & WASTEWATER OPERATIONS SUBJECT: APPROVAL TO AMEND THE EXISTING CONTRACT WITH G & G ENVIRONMENTAL COMPLIANCE, INC. FOR INDUSTRIAL PRETREATMENT PROGRAM SERVICES THROUGH FISCAL YEAR 09/10 IN AN AMOUNT NOT - TO -EXCEED $98,175 FOR FISCAL YEAR 07/08 AND SUCCEEDING YEARS. DATE: MAY 10, 2007 BACKGROUND: The City of Colton's Pretreatment Program is required under existing federal pretreatment program regulations (40CFR403) and NPDES Permit No. CA0105236. California Regional Water Quality Control Board, Santa Ana Region adopted Order No. R8-2005-0075 on September 30, 2005. The adopted Order issued the NPDES Permit, which states that the City is to maintain a Program that provides inspection, monitoring, enforcement, reporting, commercial and industrial user plan check, waste strength determinations used to calculate commercial and industrial discharge rates and activities to ensure compliance with the discharge requirements of the NPDES Permit. Domestic (residential), industry, and treatment plant sample data will be collected to gather the necessary information. The new information will then be analyzed to determine the best strategies for allocating pollutant limitations in a manner that creates the least impact on our commercial/industrial users. DISCUSSION/ANALYSIS: The City's Wastewater Reclamation Facility (WRF) has added treatment capacity since the previously issued permit and the discharge limits, contained in the new NPDES Permit No. CA 0105236, have changed to reflect new water quality standards established by the State of California. As a result of the aforementioned changes, the permit requires the City to re-evaluate the existing local discharge limits for commercial and industrial discharges to ensure adequacy and that the limits reflect current conditions. G&G Environmental Compliance, Inc. has completed the initial review for "pollutants of concern" which is the first stem in this re-evaluation process. The existing contract with G&G Environmental Compliance, Inc. expires on June 30, 2007. The local limits evaluation process is a 5-6 month process which involves, collecting additional treatment plant monitoring data, analyzing the data to determine treatment plant pollutant removal rates, inhibition (interference) rates for the biological processes, developing a draft local limits document, meeting with affected commercial/industrial dischargers to discuss the potential impacts on their operations, review and approval of the State and US EPA, Public Hearing(s) and adoption of the approved limits by the City of Colton.
