The Kansas Department of Health and Environment (KDHE) is soliciting comments until Jan. 21 on a proposed air quality construction permit for a 94-MW power project of Tradewind Energy.
Tradewind Energy plans to install 10 new spark ignition Wartsila four-stroke lean-burn (4SLB) reciprocating internal combustion engine (RICE) units using pipeline quality natural gas for fuel. Each engine will be nominally rated at 9.4 MW for a combined power output of approximately 94 MW.
The facility will also include a 3 million British thermal units (MMBtu) per hour gas heater, a 150 horsepower (hp) emergency fire pump, a 324 hp emergency diesel generator, up to 4 circuit breakers, and a 309,000 gallon fuel oil storage tank.
The proposed facility, known as the Lacey Randall Generation Facility LLC operation, will be located in Thomas County, approximately 3.5 miles northeast of Colby, Kansas.
A revised December 2013 air permit application, written by consultant Burns & McDonnell, said about the project’s air emissions: “Pre-combustion and controlled combustion systems coupled with state-of-the-art pollution control equipment and consistently achievable emission limitations has been selected as BACT for this Project. Emissions of NOx from the RICE will be limited by lean burn combustion and further reduced and controlled by selective catalytic reduction (SCR) systems. Emissions of CO and VOC will be limited by good combustion practices and further reduced by oxidation catalysts (also referenced as a CO catalyst). Use of clean fuels and good combustion practices will control emissions of PM/PM10/PM2.5. Greenhouse gas emissions will be limited by the use of efficient lean-burn engines, and by use of natural gas as a fuel.”
The application said the Lacey Randall project, located in western Kansas, is in an area that is experiencing significant expansion of both wind energy resources and oil/gas exploration. “The Lacey Randall reciprocating gas engine facility is being developed to meet both of these demands while having little impact to water resources that are vital to the state’s farming interests,” it added.
