Frivolous and insubstantial requests for a hearing may be denied by the secretary. An exemption shall be conditioned on monitoring, testing, analyzing or other requirements to insure the protection of the public health. An exemption granted shall include a schedule of compliance under which the public water supply system is required to meet each contaminant level or treatment technique requirement for which an exemption is granted within a reasonable time as specified by the secretary.L. 1977, ch. 212, § 9; April 14.
