Q12) Is there information on the type of rock on Site 1?

A12) The Geotechnical Report for the project by Schnabel Engineering, dated May 21, 2018 describes the site geology and characterizes how the elevation to “rippable rock” and to bedrock were determined. The Geotechnical Report was included with the solicitation documents. The Geotechnical Report provides seismic profiles taken on site 1 which give good information in the immediate vicinity of the seismic line shown in the report. The report notes that variability of the rock surface can be substantial and that there is also the possibility of large boulders which would require breakup and disposal as rock. Note that blasting is not allowed on site. The CLIN for rock is a good faith estimate of the rock that is likely to be encountered to establish a unit price for the excavation and hauling of the rock.

Q13) What is the frequency of fuel deliveries to the power plant Building 714?

A13) Fuel is generally delivered not more than once per week. Shut down of the roadway to the north and west of Building 714 can be accommodated for 2‐3 days at a time.
