The Interplant Digester Gas Pipeline (IDGP) was installed in 1993 to connect Plant No. 1 and Plant No. 2 with the dual purpose of providing both gas transmission between the plants and gas storage. The IDGP is approximately 20,160 linear feet in length and the original steel pipeline ranges from 12 to 18 inches in diameter.
