Evidence does not exist to categorically attribute the damage to a specific cause; therefore, judgment has to be applied.

Gerity, P.E., Pioneer Rrn;n~^*±g, provided the T~tums with a "Progress Report ce ThttmtHouse Subsidence Issues" ce April 12, 1995. 'Therein, he reference3 the .~.ttwooll Report, characteriz- ing it as having concluded that "mining related subsidence could have caused the problem.° (GPSity Report at 1.) In his opinion, OSM "used an incorrect model in their catfuter subsidence analysis. 'The wrrect model indicates that mine-influenced ground mcvet~nt could certainly have affected the Tatum house." ~. II~ reviewed both of these reports and in a marorand~an dated April 14, 1995, Pendleton stated: All the professionals irnolved agree that the Tatum resi- dence is evidencing extreme structural distress. In -n5' opin- ion the conclusion of Messrs. Gerity and Attwooll is that it hasn't been exhaustively demonstrated that subsidence did not cause the phenamna observed. I have discussed these reports with Mike Rosenthal of the OSM. Based on our professional experience in subsidenr~ observation aryl evaluation, both Mr. Rosenthal and I are of the opinion that there is insuf- ficient evidence for us to conclude that subsidence caused the pt~s~a observed at the Tatum residence.

At page 4-5, he stated: "We understand that other isrvestigators have concluded that surface movem°nts due to coal mine subsidence are a lilaely reason for much of the damage to the house.
