From The Daily Standard:

  A manure digester located in Oregon is similar in scope and operation to a facility that Optional Energy Partners of Florida wants to build near Celina, according to those involved.
Hooley Digester, a public facility owned by the Port of Tillamook Bay, was constructed in 2003 to process manure from Tillamook County into electricity and other bio-products.
The plant cost about $4 million when $2.5 million in studies, permits and legal wrangling are accounted for, according to George DeVore, operator of the Hooley Digester.
The ultimate goal, according to Port of Tillamook Bay commissioner Jim Young, is better manure management. There are 30,000 dairy cows in Tillamook County and most dairy farmers spray liquefied manure on their fields.
