The steel has ~ <br />rusted and ~ <br />delaminated leaving <br />the liner unsuitable for <br />long-term use. <br />As part of the outlet works repairs, the steel lined pipe sections will be removed and <br />replaced. <br />Planned improvements are intended to provide for the continued safe operations of the <br />dam and provide improved operational flexibility and safety. <br />ANALYSIS OF ALTERNATIVES AND SELECTED ALTERNATIVE <br />The purpose of this project is to implement several repairs and improvements to correct dam safety <br />deficiencies and improve the long-term operations at Milton Dam. The two primary concerns with the <br />outlet works are the degraded state of the upstream outlet gates and the deteriorating condition of <br />sections of the outlet pipes where steel liners were previously required to repair cracks in the original <br />cast iron pipe section. Secondary improvements will be to provide FRICO with the ability to operate the <br />outlet gates remotely. Four alternatives were considered for this project: <br />1) Do nothing <br />2) Replace the upstream outlet gates only <br />3) Repair the outlet conduits only <br />9 <br />
