Air Quality Permitting: Southeast Idaho Energy (SIE) Power County Advanced Energy Center (PCAEC)

 

Because of the level of interest from the members of the public and the complexity of this proposed project, DEQ is making the permit to construct (PTC) application materials available in advance of the required public comment period.

Comments are not being accepted at this time.

 
 Proposed Project

Southeast Idaho Energy (SIE) submitted an application for a Permit to Construct (PTC) in July 2007. In April 2008, SIE withdrew that application and submitted a revised PTC application. The revised project is for a facility to gasify coal and petcoke to produce nitrogenous fertilizers and sulfuric acid. Major components and changes include:

 

  • Gasify ~2,000 to 2,300 tons per day of coal and coal/petcoke blends.

    Reduced from 3,000 to 4,000 tons per day proposed in July 2007.
  • Install two GE gasifiers (one for production, one in hot standby as backup).

Revised compared to the single large Conoco Phillips gasifier proposed in July 2007.

  • Proposed products: ammonia, urea, urea ammonium nitrate (UAN), sulfuric acid, and slag/frit for sale for road mix or other uses.

    Deleted production of Fischer-Tropsch diesel fuels and naphtha for this project phase.
  • Power for all facility operations will be supplied by the local utility.

    Deleted on-site power production capability compared to July 2007 proposal.
  • The proposed site is about 6 miles southwest of American Falls, just south of the Lamb Weston potato processing plant.

    No change compared to July 2007 proposal.

July 2008

NEW: SIE submits Addendum No. 1 to add an option to install a Claus Sulfur Recovery Unit instead of a Haldor-Topsoe Wet Sulfuric Acid Plant. This will allow flexibility to produce either (but not both) elemental sulfur or sulfuric acid.

July 2008 DEQ finalizes completeness determination.
August 2008 DEQ issues draft permit and statement of basis for a 30-day public comment period. As already requested by the Shoshone-Bannock Tribes and members of the public, DEQ will hold public information meetings early in the public comment period to explain the technical analysis and the basis for the draft permit conditions.  Exact dates, locations, and times have not yet been set.
