WATER qUALITY STANDARDS

Pur~ ~uant to the provisions of Section the 1967 S~pplement t6 the General Statutes of Connec notice was published in the Connecticut Law Journal 26, 1970 that the W.ater Resourc~s~ Commission ado on November 17, 1969 Water Quality Standa~d~s for all and intrastate waters in the State of Connecl that, under the Federal Water Pollution Control Act of Interior approved said standards in th~ir’~antirety on Apri~l 21, 1970 insofar as the said standards apply to interstate wa~er9.

The Commission~ reserves the right to amend or extend the followin~ criteria as improved standard methods are developed or revisions consistent with the enhancement of water quality are justified.
