K.P. Kauffman Company was notified of the potential historial release around the Nelson H. Milton F #1 flowline. On September 9, 2015, K.P. Kauffman investigated the area by boring 11 holes surrounding the area of concern. It was discovered that there were multiple borings around the flowline that showed signs of contamination at depths of 1-3 feet. KPK has performed a pressure test on all flowlines in the vicinity, including the flowline that could have caused the historical release. 400897272 false 2015-09-09T00:00:00-06:00 40.121841 -105.016428 FEE 0 0 0 false <_x0032_7_approved>false I false 0 Unknown Unknown 0 0 false true true false false 0 2015-09-09T12:11:38.233-06:00 400897272 400897347 TOPOGRAPHIC MAP MILTON H.
