(4) A Type 8 outlet inspection shall consist of a <br />complete Type A inspection, a close Inspection of the Interior of the <br />conduits, outlet wells, and access ways, and testing of the outlet <br />valve(s) throughout the full operating range. In cases where the <br />conduits are too small for a person to safely enter, the owner shall <br />provide for an Inspection using video. or other remote sensing <br />equipment capable of detecting flaws or Imperfections within the <br />conduit. A written report of Inspection findings, including the <br />opinion of the owner's engineer, must be submitted to the State <br />Engineer unless waived by the State Engineer for good cause. A Type 8 <br />Inspection of the normally inundated outlet conduit of a dam without <br />upstream guard gates shall be requried only when existing baseline <br />data available to the State Engineer is inadequate 'to permit an <br />evaluation of the condition of the outlet conduit.
