HMMH successfully delivered two highly complex Environmental Assessments (EAs) for the FAA: Greener Skies over Seattle and Houston Optimization of Airspace and Procedures in the Metroplex (OAPM).
The Finding of No Significant Impact (FONSI) and Record of Decision (ROD) for the Greener Skies EA (November 2012) served as the final agency determination and approval for the proposed action which implements new Area Navigation procedures at Seattle-Tacoma International. HMMH led the consulting team and served as the technical lead for most impact categories.
The FONSI and ROD for the Houston OAPM EA (June 2013) approved proposed actions consisting of development of air traffic control and airspace procedures to establish and maintain safe and efficient handling and movement of traffic into and out of the Houston, Texas Metroplex airspace. HMMH managed the EA and served as the technical lead for all impact categories.
