Mr. Blair Bennett July 15, 1996 Page 2 from other HDR offices reviewed the nature of the problem and the regional water quality conditions); and the hiring of an outside contractor to perform all required clearing. HDR has repeatedly been in communication with PWS to clearly ascertain their perception of the extent of clearing that will be required. The original clearing was to 650' msl, and the secondary clearing was initially targeted by PWS for that same level, but as HDR reviewed the language of the rules governing public water supply it appeared that a case could be made to limit the secondary clearing to 646' msl, the "normal operating pool." Discussions with PWS led to acceptance of the 646' level, which substantially reduced the County's secondary clearing obligations. Having established the elevation of clearing requirements, HDR flagged representational elevations for reference by the contractor. The 646' level was also included in the draft specifications/clearing plan, which was presented to PWS for their review. Task 200 - Communications/Coordination Efforts for Approval and Implementation of Clearing Plan At the secondary clearing meeting held at the Coddle Creek Water Treatment Plant on July 1, 1996, Terry Gross of PWS approved the draft specifications/clearing plan that included both the 646' level for clearing and the concept of approving clearing by sections. The prospective contractors who have examined the site had expressed concern that there might be a need for multiple clearings of portions of the reservoir if there was some regrowth in areas before the whole project was complete. The acknowledgment by PWS that sections may be checked off as complete enabled the contractors to more precisely estimate the extent of the work, and thereby lower the cost estimate. Leading up to, and following, the meeting of July 1, HDR has worked on behalf of the County to solicit qualified contractors to informally bid to perform the secondary clearing. By the date of the meeting, HDR had called and/or met with numerous contractors to discuss this 'project. Three contractors/contractor teams that were most qualified ultimately submitted estimates to do the work. HDR has had ongoing communication with the County regarding these developments, and has visited the site with the contractors on repeated occasions as they have sought to clarify the parameters for their bids. Through discussions with Mr. Fletcher Hartsell, HDR has also reviewed the prospect of using the original clearing contractor; that consideration, however, was ultimately proven untenable. To date, two of the three contractors that presented an informal bid for the secondary clearing have followed up with a revised final estimate; the third contractor's estimate is expected within the next few days
