RE: Cooling Tower Inlet Testing Question
Hi. Kevin and Ned, our measurement experts, say that both the sampling locations are fine. 
 
Best of luck with the testing and thank you for your efforts.

Subject: Cooling Tower Inlet Testing Question
 
Good afternoon Dr. Jones,
 
We are preparing for the cooling tower inlet test the week of October 24th.  Per Appendix P Section 5.1.1.3, samples should be drawn from either the vertical section near the base of the riser pipe (from the inside of the elbow to the riser) or the top of a horizontal section prior to the riser pipe at a location where the pipe will be completely full.  At Clairton, the by-products water-cooling tower piping system has a main header that splits into two, approximately equal flow, pipes that feed the east and the west sides of the water-cooling tower.  There is no accessible location for the main water-cooling tower header and no existing ports prior to the bases of the east or west risers.  There are existing access ports on the horizontal sections prior to the risers where the pipe will be completely full.  However, only one of these ports, the west side, has access to the top of the pipe conforming with Section 5.1.1.3.  The east side's access port is approximately 90 degrees from top or parallel to the ground.    
 
U. S. Steel will move forward with testing both the east and west sides of the water cooling with the existing access port locations.  Flows can be determined for both locations and are expected to be approximately the same for both the east and west sides.  Please let us know if the EPA prefers testing as proposed or to test only the access port that meets the Method where the results could be applied to the other side.
 
Thanks,
