FONSI/ ROD Conditions Monitoring Report


September 30, 2022

On March 21, 2022 the Federal Aviation Administration (FAA) issued a Finding of No Significant Impact (FONSI) / Record of Decision (ROD) for the Trenton-Mercer Airport Terminal Area Improvements Environmental Assessment (EA).  As a condition of the FONSI/ROD the FAA required that all permit requirements/mitigation measures be tracked and monitored and that updates would be provided biannually.  The FAA also required the updates to be posted on a project-specific website in a manner that is readily accessible to the public.


In accordance with the requirements of the FONSI/ROD, Mercer County has assembled the Conditions Monitoring Tracking Log. The log will identify environmental conditions and associated planning, design, permitting, mitigation, and construction activities that require environmental permitting and/or mitigation.


During the first reporting period, which was through the end of September 2022, many of the project elements have little or no activity. This was the result of a Notice to Proceed (NTP) being issued by Mercer County  for design of the terminal on October 17, 2022. As a result, no design, permitting, construction, site investigation, or mitigation activities occurred through the period ending September 30, 2022.


As the design proceeds, coordination with agencies overseeing environmental permitting will occur. Such agency coordination will involve the following:

  • Meetings with the reviewing agencies

  • Development of exhibits

  • Development of permitting documents; that will incorporate agency comments and the requirements for each permit such as mitigation measures.


As progress is made with the reviewing agencies, corresponding design, and permit application documents, the County in conjunction with their design team will update the Conditions Monitoring Tracking Log.  Following the completion of essential task and milestones,  this log will be updated by the County and the construction management team. These updates will be based upon implementation of the plan,  permitting documents developed, and mitigation requirements.
