From the Purpose: "The purpose of these documents is to improve preparedness for response and recovery operations following an acute waterway debris incident in coastal Mississippi. The term acute waterway debris incident is used to describe an incident - either natural or anthropogenic - that results in the release of large amounts of waterway debris. The 'Comprehensive Guidance Document' and complementary 'Field Reference Guide' outline existing response structures at the local, state, and federal levels to facilitate a coordinated, well-managed, and immediate response to potential waterway debris incidents impacting the state of Mississippi. Organization roles and responsibilities are presented in a consolidated one-page flowchart which functions as a decision tree for waterway debris response. Additionally, permitting and compliance requirements for waterway debris removal have been synthesized in a one-page reference handout"
