General Overview

  • developing, training, and testing a comprehensive emergency response plan for Maricopa County;
  • developing procedures by which regulated facilities notify the LEPC in accordance with EPCRA;
  • developing procedures for addressing requests from the public under the right-to-know provisions of EPCRA;
