The 2010 Federal Boiler MACT Rule forced universities throughout the Midwest powered by boilers to comply with the new air emissions regulation. The new rule placed demands on the mercury and particulate matter emitted in order to meet new limits on hydrogen chloride and other acid gases.

In order to comply, The University of Northern Iowa requested sealed bids to add a common hydrated lime based Dry Sorbent Injection (DSI) System to the flue-gas breaching for Units 3 and 4 at the University Power Plant site. 

The DSI turnkey system also included a sorbent storage silo, feed equipment, and conveying equipment and piping. As part of a $2.28 million genera contract, Carl A. Nelson & Company was responsible for design, supply and installation of the storage silo and the related piping, electrical equipment, cables, conduit, controls, supports, enclosures, CMU electrical room, concrete retaining wall, pavement, supplemental steel, foundations, platforms, and concrete.
