Subsequently, the work related to the digester gas plug valves at the Egan WRP was deleted from the project because Digesters A, B, C, and D at the Egan WRP can not be individually isolated for this work. The work will be added to Project 11-403-3P, Membrane Gas Holder Replacement and Digester Cleaning, EWRP. The estimated cost of this project is to be decreased from $7,500,000.00 to $6,500,000.00.

1. Removal and replacement of the digester gas plug valves.
2. Installation of pneumatic actuators and associated electrical controls.
3. Installation of an air receiver, pressure regulators, and associated piping.
The purpose of this project is to improve the routing of the digester gas piping to provide more accurate flow measurement and prevent the build-up of condensation and debris; replace the digester gas valves that have reached the end of their useful life; replace air handling units and improve the efficiency of the circulating systems; and provide new actuators on digester gas valves to ensure the safety of the plants and personnel.

2. Egan WRP -install a new flow meter for the digester gas pipeline that feeds the emergency generator; and install a drip leg on the digester gas line in the gas compressor room.
The estimated cost of the project is $6,500,000.00.
The revised tentative schedule for this contract should be as follows:
