  3. Community Public Water Systems:
    The owner or operator of a community water system shall publish the notice in a daily newspaper of general circulation in the area served by the system. If the area served by the public water system is not served by a daily newspaper of general circulation, the notice shall be published in a weekly newspaper of general circulation serving the area. If the area is not served by either a daily or weekly newspaper of general circulation, notice shall instead be issued by hand delivery or by continuous posting in conspicuous places within the area served by the system. [30 TAC 290.122(2)(A)] (skip to step 4)

  4. The owner or operator of the public water system must issue a notice when the public water system has corrected the violation. This notice must be issued in the same manner as the original notice was issued. [30 TAC 290.122(b)(4)]
  5. Copies of all notifications required must be submitted to TCEQ within ten days of its distribution. [30 TAC §290.122(f)]
