monitoring and repair on Stevens Gulch Road. The plan should also include subsidence

Panels 24, 26, and 28, to verify BRL's subsidence prediction for the road; and include those
monitoring stations in the list of monitoring stations presented on pages 2.05 -177 and -178 of
the permit application package (Rule 2.05.6(6)(c)).
