DEQ to move Mobile Command Center out of Bayou Corne for routine maintenance

BATON ROUGE – On Monday, June 30, DEQ will move its Mobile Command Center out of the Bayou Corne area for relocation to DEQ Headquarters in Baton Rouge.

The Mobile Command Center will undergo routine maintenance in preparation for hurricane season. During the tropical storm and hurricane season, the unit is used as a mobile logistical and operational resource in support of DEQ’s emergency response mission.

DEQ environmental scientists will continue to conduct air monitoring, water monitoring and soil testing at Bayou Corne and will continue to work with local, state and federal partners in ensuring for the protection of human health and the environment.  

Upon completion of the maintenance, the Mobile Command Center may return to Bayou Corne should the need arise.
