EPA v. MIDFIELD AVIATION LLC

Case summary

Region 10 Settles with Midfield Aviation, LLC, for Clean Water Act (CWA) Violations (Caldwell, ID) On November 3, 2021, EPA Region 10 filed an industrial non-filer expedited settlement agreement resolving CWA NPDES violations by Midfield Aviation, LLC for their operation at the City of Caldwell's Industrial Airport in Caldwell, Idaho. EPA Region 10 determined Midfield Aviation, LLC required coverage under the EPA Stormwater Multi Sector General Permit (MSGP). EPA Region 10 made this determination following an October 2019, inspection conducted by Idaho Department of Environmental Quality (IDEQ) on behalf of EPA, which also resulted in EPA Region 10 issuing an administrative compliance order on consent with the City of Caldwell. EPA Region 10 alleged that Midfield Aviation, LLC violated the NPDES program of the CWA at the Airport by failing to obtain coverage under EPA?s MSGP. Midfield Aviation, LLC has obtained coverage under IDEQ's industrial stormwater permit and began implementing its requirements. The estimated cost of injunctive relief is $600. Actions taken by the facility should reduce discharged pollutants from industrial activities associated with airports into receiving waters.
