Shibl /Jl t. City Solicitor RE: Meeting Agenda -- June 13 1994 DATE: June 6, 1994 1. Sewer Ordinance Amendments (Ordinance attached) 2. Pretreatment Fees (Order attached) 3. Sewer Rate Study Update 4. Executive Session - Negotiations The purpose of this memorandum is to provide you with some background information on the above agenda items. As you are aware, the meeting will take place at 7:30 a.m. on Monday, June 13th in the Third Floor Conference Room at City Hall. 1. Sewer ordinance Amendments - The Ordinance amendments have been proposed as part of ongoing efforts to administer the City's Industrial Pretreatment Program. These technical amendments to the definitions of Excessive Loading and Normal Domestic Sewage are necessary to set an upper limit of oil and grease concentration within those definitions. The reason for this action i n part due to increases in the amount of oil and grease being observed in the City's wastewater. For example, the City recently removed 2 1/2 tons of oil and grease from the K -Mart Pump Station in the Mall area. Staff is working to identify the source of this oil and grease, and this Ordinance change will aid in future enforcement action, if necessary. A related issue, and one that should save money for permit holders due to decreased sampling costs, is an administrative raising of the local limit level of concentration entration for oil and grease to 200 mg/l to correspond to the prohibited discharge level. One of the permit holders has had a difficult time meeting the current 100 mg/l level which has resulted in additional lab costs for each reading above 100 mg/l.The new local limit level, which has been approved by the EPA, should reduce these costs, as well as the Pretreatment Coordinator's administrative coats. Staff would recommend approval Of these technical amendments to the Ordinance. 2. Pretr¢atment Pees - AN you are aware, the new Treatment Plant has been ing and meeting permit requirements for over a year. The Ordinance amendments passed on November 22, 1993 authorized the setting of various fees by Council Order to cover the administrative expenses of the Plant's Pretreatment Program. The EPA requires the City to take steps to cover the costs of the Pretreatment Program. 94-274 _2_ Treatment Plant staff have been able to calculate the coat of certain services and situations that may arise during the administration of the Pretreatment Program. Some of these, such as the surcharges, are based on the actual cost to the City for treating excessive loadings or excess flows based on a year of Plant operating cost data. These surcharges may have to be adjusted in the future depending on the Plant's then current operating costa. The appeal fee covers the costs of organizing, including notification of abutters, an administrative appeal and is the same as filing an appeal of a Court action. The permit fee includes approximately $100 for processing the application, with the remainder assessed to monitoring permit holders and collecting samples. Lab costs for analyzing samples have always been handled in this manner. The permit fee is one that staff felt the current permit holders can absorb while at the same time making an attempt to cover the City's casts. This Order requires a recommendation for action at the June 13th Council Meeting as all permit holders are in the process of applying for new permits. Thus, authorization is needed for the permit fee being assessed. Staff would recommend your approval. 3. Sewer Rate Study Update - CH2M-Hill has provided a draft of the Stormwater Utility part of the sewsor rate study. Staff will be prepared to give a brief summary of staff's thoughts or comments on the draft. CH2M-Hill will address these comments, together with earlier comments on the first part of the Sewer Rate Study, in the Final Report. 4. Executive Session - Staff will update Committee members on the current statue of the Hampden/Hermon Interlocal Agreements. to Attachments pc: Ralph Mishou, MMTP Superintendent Al Jellison, WWTP Pretreatment Coordinator Jim Ring, City Engineer Edward Barrett, City Manager Marie G.
