06-096 C.M.R. ch. 585, § 1 - Identification of Fish Spawning Areas
Prior to the licensing or relicensing of any wastewater discharge which may affect the dissolved oxygen content of Class B or C waters, the Department shall request the Commissioner of the Department of Inland Fisheries and Wildlife to identify existing and potential fish spawning areas in the receiving water, according to section 2 of this rule, in which higher concentrations of dissolved oxygen are required to ensure spawning, egg incubation, and survival of early life stages of fish species. In Class B waters that have been identified as fish spawning areas, no activity may cause the dissolved oxygen concentration to fall below a 7-day mean of 9.5 parts per million or a 1 day minimum of 8.0 parts per million during the period October 1 to May 14 of the following year.
