a) Restricted status is defined as the Agency determination, under Section 39(a) of the Act and Section 602.105, that all or part of a community water supply facility may no longer be issued a construction permit without causing a violation of the Act or Board or Agency rules. Board rules whose violation can result in a restricted status determination include rules establishing maximum contaminant levels, treatment techniques, source water quantity requirements, treatment unit loading rates, storage volume requirements, and minimum pressure for a distribution system.
- 1) When the Agency cannot issue a construction permit to a community water supply because that issuance would extend an existing violation of the Act or Board or Agency rules, the Agency must place the community water supply on restricted status.
- 2) Except as specified in Section 602.105(a)(6), the Agency must not issue a permit for water main extension construction when the water main would extend an existing violation of the Act or Board or Agency rules.
- b) The Agency must publish on its website and in the Environmental Register and update, at intervals of not more than three months, a comprehensive list of community water supplies subject to restricted status. This list will be entitled the "Restricted Status List".
- c) The Agency must notify the owners or official custodian and Responsible Operator in Charge of a community water supply when the community water supply is initially placed on restricted status by the Agency.
- d) The restricted status list must include a statement of the potential or existing violation of the Act or Board rules that caused the community water supply's inclusion on the list.
- e) Owners or official custodians of community water supplies that have been placed on restricted status must notify any person requesting construction of a water main extension of this status.
