less of the natural streambed and where the water is returned to
the same stream shall be:
(1) The minimum average flow for a period of seven
consecutive days that would have an average
occurrence of once in 10 years in the absence of the
dam, or ten percent (10%) of the average annual flow
of the stream in the absence of the dam, whichever
is less, if prior to 1 January 1995 the small power
producer was either licensed by the Federal Energy
Regulatory Commission or held a certificate of
public convenience and necessity issued by the North
Carolina Utilities Commission.
(2) The minimum average flow for a period of seven
consecutive days that would have an average
occurrence of once in 10 years in the absence of the
dam, or ten percent (10%) of the average annual flow
of the stream in the absence of the dam, whichever
