The City, through its legal <br />counsel, is working with Ohio EPA to set the copper and other metals at a reasonable level in <br />the NPDES permit. In the meantime, the City received new findings and orders from the <br />USEPA concerning the city meeting its current NPDES permit limits. <br />Therefore, in accordance with your request, URS is pleased to submit the following proposal <br />to further analyze and determine the source of higher copper readings. <br />Our understanding of the project include the following tasks: <br />Review North Olmsted Wastewater Treatment Plant and Environmental Control Laboratory <br />(EC Labs) procedures for scheduled sampling and lab analysis. This review includes <br />reviewing the study EC Labs is performing per their August 9, 1991 letter. <br />• Review the City's pretreatment program including procedures, individual industries, and <br />sample results obtained by the City. <br />• Design, implement and analyze results of a program to collect samples and tests from <br />various locations through the sanitary sewer collection system. In order to minimize cost <br />while breaking the system into small segments, we propose to perform this task in phases. <br />Phase I would consist of six sites. Phase I results would be analyzed and if one or two sites <br />should have high copper levels, then Phase II would place additional samplers and monitors <br />upstream to further subdivide the area to isolate and identify the source (see description of <br />Phase n. <br />
