Section Env-Ws 347.02 - Variances and Exemptions from the Maximum Contaminant Levels for Organic Chemicals(a) The required technologies listed in Env-Ws 347.01 shall be the best technology, treatment techniques, or other means available for achieving compliance with the MCLs for organic chemicals specified in Env-Ws 315.01 and Env-Ws 347.03.(b) The department shall require community water systems and non-transient, non-community water systems to install and use any treatment method identified in Env-Ws 347.01 as a condition for granting a variance except as provided in (c), below. If after the system installs the treatment method the system still cannot meet the MCL, the system shall be eligible for a variance.(c) If a system can demonstrate through comprehensive engineering assessments, which may include pilot plant studies, that the treatment methods identified in Env-Ws 347.01 would only achieve a de minimis reduction in contaminants, the department shall issue a schedule of compliance that requires the system being granted the variance to examine other treatment methods as a condition of obtaining the variance.(d) If the department determines that a treatment method identified in (c), above, is technically feasible, the department shall require the system to install and use that treatment method in connection with a compliance schedule issued. The department's determination shall be based upon studies by the system and other relevant information.(e) The department shall require a public water system to use bottled water or point-of-use devices or other means as a condition for granting a variance or an exemption from the requirements of Env-Ws 315.01 to avoid an unreasonable risk to health.(f) Public water systems that use bottled water as a condition for receiving a variance or an exemption from the requirements of Env-Ws 315.01 shall meet the requirements of Env-Ws 308.11 concerning bottled water.(g) Public water systems that use point-of-use devices as a condition for obtaining a variance or an exemption from Env-Ws 315.01 for organic chemicals shall meet the applicableconditions of Env-Ws 308.N.H.
