Document Type
MND - Mitigated Negative Declaration

Document Description
The City of Turlock is adding disinfectant at 18 wells and three storage tanks within the City’s water system (21 sites total). Sodium hypochlorite will be injected on the pipe manifold of each well and discharge manifolds for each of the tanks. A sampling port located at least ten pipe diameters downstream from the injection point will draw approximately 10 gallons/hour of water for the chlorine analyzer which will ensure that the level of chlorine in the water entering the distribution system is within the appropriate limits. The waste stream from the analyzers will be discharged to the sewer at a rate of 10 gallons per hour. The sodium hypochlorite will be a 12.5% liquid solution that will be stored in double-contained approximately 250-500 gallon tanks. An approximately 10 foot by 12 foot prefabricated enclosure will be added to each well site to house the sodium hypochlorite and chlorine analyzer. Each of the tank sites have a spare room in the existing pump buildings which will be utilized to house the sodium hypochlorite and analyzers. An eyewash station and shower will also be installed near the chemical storage location in case of emergency.
