Section Env-Ws 308.02 - Point-of-Entry Treatment(a) Point-of-entry (POE) treatment shall be used only where: (1) There are no non-contaminated sources reasonably available; and(2) Centralized treatment is not feasible .(b) To obtain approval to install POE treatment, the owner of the water system shall submit the following in writing to the department:(1) The name, location, and EPA identification number of the system;(2) The contaminant(s) proposed to be treated by the POE devices;(3) An explanation of the system's attempts to locate non-contaminated sources; and(4) An explanation, with supporting documentation, of why centralized treatment is not feasible.(c) The department shall approve a POE treatment concept if it determines that: (1) A non-contaminated source is not available to the water system;(2) Centralized treatment is not feasible; and(3) The POE devices will provide equivalent treatment.(d) The public water system owner shall operate and maintain each POE treatment unit.(e) The public water system owner shall develop a monitoring plan consistent with Env-Ws 320 through Env-Ws 329 and obtain department approval for that plan before installing any POE device. Under the plan approved by the department, POE devices shall provide health protection equivalent to central water treatment. The monitoring plan for POE devices shall also include physical measurements, observations such as total flow treated, the mechanical condition of the treatment equipment, the microbiological purity of the water, and a maintenance schedule.(f) The design submittal for the POEtreatment shall include the following certifications: (1) The owner shall certify the performance, field testing, and, if not included in the certification process, shall conduct an engineering design review of the POE devices for all contaminant categories, at all relevant flow rates; and(2) The certification of the design and application of the POE devices shall consider the tendency for an increase in heterotrophic bacteria concentrations in water treated with activated carbon.(g) The layout of the installation shall insure that all consumers shall be equally protected. Every building connected to a system for which a POE treatment is allowed shall have a POE device, which is installed, maintained, and adequately monitored. The owner shall submit data documenting that every building is subject to treatment and monitoring. If POE treatment is used, it shall remain a permanent part of the supply and shall not be separated by sale, lease, or other conveyance of the property.N.H. Code Admin. R. Env-Ws 308.02
