The Indiana Department of Environmenta Management on Dec. 2 approved an air permit for a small power project in Elkhart County to be fired by biogas.
On Aug. 12, the department’s Office of Air Quality (OAQ) received an application from Green Cow Power LLC related to the construction and operation of a new electricity generating facility, combusting biogas produced from anaerobic digestion of animal manure and other non-hazardous biologically-based wastes.
The Green Cow Power (GCP) energy center and two Martin dairy farms are located on adjoining properties. The Martin dairy farms will send all of their manure to the GCP energy center through a manure pumping system and by truck. GPC and the Martin dairy farms have different owners. The owner with the largest percent of ownership in the GCP energy center, Organic Power Consulting LLC, has no ownership interest in the Martin dairy farms. The sole owner of the two dairy farms, Brent Martin, has only a 1/6 ownership interest in the GCP energy center.
The electrical output of the energy center is to be distributed to the grid through NiSource, the purchaser of the electricity. None of the electricity generated by GCP is distributed directly to the Martin dairy farms. A secondary product of the energy center is digested liquid waste which can be used as fertilizer.
The project includes three digester gas-fired engines, identified as EU-01, EU-02 and EU-03, each with a maximum capacity of 1,573 horsepower (9.7 MMBtu/hr), each using acatalytic oxidizer for carbon monoxide and formaldehyde control, and exhausting to stacks S-01, S-02 and S-03, respectively.
