CITY ENGINEER/UTILITIES DIRECTOR 150 N.LAKESHORE DRIVE•OCOEE,FLORIDA 34761 (407)656-2322 MEMORANDUM DATE: February 24, 1994 TO: The Honorable Mayor and Board of City Commissioners FROM: James W. Shira, P.E. City Engineer/Utiliti Director SUBJECT: Contract Award - Corrosion Control Study On June 7, 1991, the U.S. Environmental Protection Agency published final national primary drinking water regulations for lead and copper in the Federal Register. These regulations have collectively become known as the Lead and Copper Rule. This Rule describes a series of sampling and testing actions that a water utility must take to determine the level of lead and copper found within the water source, within the distribution system, and at the consumer's tap. The Rule established a concentration for each of these elements which, if exceeded, triggers further action by the utility. These concentrations are called Action Levels, and are 0.015 mg/L for Lead , and 1.3 mg/L for Copper. The City of Ocoee has completed both the initial and follow-up rounds of tap water sampling, and like many other inland utilities, has found that the number of tap samples that exceed the Action Level for Copper is above the number allowed by the Rule. We sampled water drawn directly from the wells, and also from the distribution system, and found that none of these samples exceeded the Action Level for either lead or copper. This means that the raw water we draw from the ground, as modified by its chemical interaction with the distribution system, is slightly corrosive to copper. This slight corrosiveness causes leaching of copper from plumbing pipes and fixtures which then shows up in the tap samples. Utility systems that exceed the Action Level for copper must initiate a Corrosion Control Study to determine which one, or which combination of the several available methods of corrosion control treatment will provide the most effective reduction in the corrosiveness of the water. This is referred to as the Optimum Corrosion Control Method. The Florida Department of Environmental Protection requires that this study be completed, and the results reported to FDEP with a recommendation for an Optimal Corrosion Control Treatment Plan, by July 1, 1994. Ott' THE PRIDE OF WEST ORANGE gfr,ibk We recently solicited proposals from interested fines for the preparation of an Optimal Corrosion Control Treatment Plan, and received three proposals and one "no bid" response. The fines which responded, and their proposed fees are C/P Utility Services Company, Inc., $9,600.00; Malcolm Pirnie, Inc., $9,500.00; and Hartman & Associates, Inc., $8,900.00. The "no bid" response was received from Conklin, Porter and Holmes-Engineers, Inc. The proposal submitted by C/P Utility was deficient in several major areas, and cannot be considered to be a complete response. Both Malcolm Pimie and Hartman submitted detailed proposals that addressed the areas of concern to Ocoee, and both firms have proposed project teams comprised of qualified professionals. However, after a careful review of both proposals, and discussions with the references provided by both firms, it is my opinion that the city will derive the greatest benefit from the services offered by Malcolm Pirnie, Inc. The information submitted by both firms indicates that the project team proposed by Malcolm Pirie has a much broader base of experience in lead and copper corrosion control and water quality issues than the team proposed by Hartman. In addition, Malcolm Pimie, as a prime consultant to the U.S. Environmental Protection Agency, was involved extensively in the development of the Lead and Copper Rule and its associated Guidance Documents. This gives the firm an intimate knowledge of the Rule, and of the means and methods that are most likely to satisfy the requirements of the Rule. I recommend that the City Commission award the contract for preparation of an Optimal Corrosion Control Treatment Plan to Malcolm Pimie, Inc. in an amount not-to-exceed $9,500.00, and authorize the Mayor and City Clerk to execute the contract documents. wesowocswcu12a \ • •_ : City of Ocoee 150 N.
