Jim Stover, company representative for Snowcap Coal Company(SCC)was <br /> present for the inspection. The weather conditions were mostly sunny with a light wind. The temperature was <br /> approximately 65 F and the ground was dry. <br /> SUBSIDENCE—Rule 4.20: <br /> The focus of this inspection was to observe the geophysical survey that took place on the Carey and <br /> Fontanari properties near the Carey pond. This investigation is one of the commitments required by SL-08 which <br /> are outlined in Tab 14,page 14-30ii of the permit. <br /> James Pfeiffer and Lincoln Steele of Fugro Consultants, Inc. conducted the investigation. <br /> The day before the investigation,Mr. Stover had 10,000 gallons of water dumped into the suspect cracks on the <br /> Carey and Fontanari properties. Mr. Stover was instructed to do this for the geophysical survey. <br /> The baseline transect was set up approximately 150 feet west and parallel to the Carey pond, oriented south to <br /> north. The first, southern most stake was placed just north of the two-track road and aligned with the southern end <br /> of the Carey Pond. A steel stake was driven in the ground several inches at 10 foot intervals along the transect <br /> (photo 1). 84 stakes were placed on the baseline transect. The length of the baseline transect was extended further <br /> to the north onto land that is not over mine workings to collect data of non-subsided soil. The transect location <br /> was recorded with a GPS receiver. The electrode connector cable was attached to each stake with a spring <br /> connector and then plugged into the switch box (photo 2). The switch box was then connected to the Super Sting <br /> R8 IP Earth Resistivity Meter(photo 3). <br /> A test was performed to determine the conductivity of each electrode stake. Several of the stakes had low <br /> conductivity so salt water was poured at the base of all the stakes to increase the conductivity(photo 4).
