Non-Compliance Issue Item #1 During the physical inspection, an assessment was conducted to determine whether the facility and equipment appear to be generally well maintained and in a fit state of repair. A visual examination of unit process equipment indicated that regular routine maintenance was being conducted in a timely manner. However the Southwold (Shedden) Booster re ch orination system was found to have sodium hypochlorite leaks and poor building ventilation which has lead to excessive corrosion of treatment equipment, support fixtures and building components. Additionally, the equipment as installed failed to meet the criteria of duty and stand byfor the chlorination metering pumps as described by the Drinking Water Works Permit issued September 20, 2011.
