Document Description
PG&E proposes to construct two additional Class II surface impoundments (Ponds 6R and 7R) in the same location as the two former ponds at their Hinkley Compressor Station facility. The two new surface impoundments would increase the existing surface impoundment area by an additional 2.48 acres for a total of 7 acres of surface impoundment. New ponds 6R and 7R would be designed to meet all requirements for Class II surface impoundments and would employ an engineered alternative liner system that would include two layers of 60-mil high density polyethylene (HDPE) geomembrane, with an integral drainage layer overlying a low permeability geosynthetic clay liner (GCL) to provide protection against leakage. A drainage layer and leak detection system is proposed between the two liners with a leachate collection and removal system.
