      (a)      Except as otherwise prohibited in subsection (b) of this section, the Department may issue a permit that allows the use of chlorine or chlorine compounds in treatment of wastewaters discharged from any publicly or privately owned sewage treatment plant to any surface waters of this State only if the treatment of the wastewaters includes dechlorination.

      (b)      (1)      This subsection is not effective unless matching federal funds are available to implement the provisions of paragraph (4) of this subsection.

            (2)      This subsection does not apply to sewerage treatment facilities that discharge an amount of treated sewage less than 1 percent of the 7-day, 10-year low flow of the receiving stream.

            (3)      The Department may not issue a permit that allows the use of chlorine or chlorine compounds in the treatment of wastewaters discharged into any waters of this State that are designated by the Department as natural trout waters and their tributaries.
