  • Experience

    • Iatan Project: Provided on-site day-to-day legal support to the owner's project management team regarding contract negotiation, contract administration and dispute resolution throughout the life cycle of the project for the purpose of maximizing financial and operational performance (i.e. cost and schedule control) and minimizing legal risk. The Iatan Project included the construction of a new 850 MW (net) supercritical, pulverized coal unit that burns Powder River Basin (“PRB”) coal. The new unit included emissions control equipment that met the Best Available Control Technology (“BACT”) standards, including a selective catalytic reduction system (“SCR”) for NOx control, a wet flue gas desulfurization system (“Scrubber”) designed to use a limestone slurry solution for SO2 control, and a pulse jet fabric filter (“Baghouse”) for particulate control. Additionally, a powdered-activated carbon system was installed to remove mercury. The project received recognition by Power Magazine as 2011 Plant of the Year.
    • Developed the regulatory strategy for construction of Iatan Unit 2, drafting the pre-filed testimony and associated data request responses, providing significant witness preparation support, and drafting the post-hearing brief for construction prudence issues in rate making hearings before the Missouri Public Service Commission and the Kansas Corporation Commission. Based on the strength of the construction project documentation and evidentiary presentation in the rate case, both states only disallowed approximately $20 million (or approximately 1%) of the Iatan Unit 2 project costs from rate base.
    • Obtained an arbitration partial award of over 91% of the owner's costs in a multi-million dollar construction dispute.
    • LaCygne Environmental Retrofit Project: Currently providing on-site day-to-day legal support to the owner's project management team regarding contract negotiation, contract administration, and dispute resolution for an environmental retrofit of two existing units composed of a coal-fired unit nominally rated 810 MW gross that uses a supercritical, cyclone-fired boiler (Unit 1) and a pulverized coal-fired unit nominally rated at 715 MW gross that uses a subcritical, wall-fired boiler (Unit 2).
