[en] This document describes the design, drilling and construction of the well RRL-2B and piezometer nest RRL-2C at the RRL-2 location. Well RRL-2B will act as the discharge well for performing large-scale hydraulic tests in units of the Grande Ronde Basalt. Piezometer nest RRL-2C will act as the primary observation points in the vicinity of the RRL-2 location. Water levels will also be measured in RRL-2C as part of the piezometer baseline monitoring program. Well RRL-2B is completed as a 12.25-in. (31.12-cm) open hole at the interim depth of 2858 ft (871.1 m). On completion of testing the Rocky Coulee flow top, the well will be deepened to the next horizon for testing. 33 refs., 25 figs., 4 tabs
