These wells <br />are located between cavities 5H. 611, and IA. There has been no indication of subsidence in 4A-5M <br />since installation. Subsidence well 3M- fDR was drilled late in 2003. Two of the four TDR cables in <br />3M-TDR subsidence well appear to have water infiltration damage. In 2009. readings were again <br />taken and data was gathered from cables two and three. In addition to the monthly NSI readings, the <br />2009 Annual Report 7 of 33
