07 DRAFT JPH MINUTES PAGE 3 of 1-40. He noted there had been 40 years without failure, but that this trend cannot continue. He continued that conservation methods were only short range solutions for crisis situations and major long term decisions are needed to go beyond the crisis. Wray indicated that the State had done some analysis based on criteria provided by the County Manager. Yield with conservation and with stream flow was reviewed.. Total yield with conservation could run to about 2.,6 mgd with the existing facilities. With no stream flow at all , it would only go up to about 3 mgd. without stream flow, the difference is one only and mgd. He noted the situation becomes more critical y .4 after year with continued growth and there would have to be some outside source for water supply. Some lon range decisions need to be made to get out of the crisis situation. Wray stated that North Carolina is a riian There are a number of state policies and lawsrwhichtdeal with the riparian question. He noted since the construction of the OWASA pipeline in 1977, which was a response to a crisis, there has been a creeping "dewate ring" of the Eno River itself and as we future with upstream diversions, OWASA, move into the System and Hillsborough itself returns onlyaaboutla50nc- 60% of the water to the streams g e percentage does not come back to theaEno River. hire e are more impacts on the river as growth continues. The riparian law states that there is a right to use the water, but there is no ownership of the water. The State has jurisdiction over the water as statutory responsibility and w l Wit well as a h planning and implementation the conflict�between tprudeer r supply and in-stream flow can be resolved but it will be costly. There is a need to determine who pays if something is done. There is also a question of what flow to be released. The State had made a recommendation using 7Q10. Wray continued that 7010 was about 1 .78 for the period 1929 - 1950 ( 1 .462) ; up to 1960 ( .869) ; and up to 1970 ( .67) . The natural 7010 of the Eno River is low. WIIlhoit asked that Wray emphasize that these figures are cubic feet per second rather than million gallons per day. Wray noted that cubic feet or 1 mgd. = 1 .5 cfs. 10 mgd per second x 1 .55 Wiiihoit then noted that theseuwould range from .4sm d to about 1 . 1 mgd. Wray concurred. g Hillsborough permit to discharge wastewaterdwasacoming up for renewal and he asked for comments from Meg Kirk on the renewal of the permit. Meg Kirk stated that the Eno River is stressed at times and this does threaten the fish and other acquatic life. She noted this was an indication of a need for water quality protection.
