The Louisiana State Police (LSP), Emergency Services Unit (ESU), is the primary agency in the state of Louisiana with both the regulatory and statutory authority for hazardous material and explosives. Each unit conducts enforcement activities which are supported by either administrative or criminal provisions within each set of regulations. Technicians assigned to ESU respond to, mitigate and often remediate hazardous material and explosive incidents throughout the state of Louisiana on a 24-hour basis, 365 days a year. The job of an ESU Technician is to ensure the citizens of Louisiana are not exposed to any undue risk of hazardous materials or explosives through proactive enforcement and by strictly enforcing and investigating infractions in the hazardous material and explosives laws.
The Hazardous Materials Hotline, 1-877-925-6595, is staffed by Right-to-Know personnel and is the central repository for chemical spills or hazardous material emergency notifications. Transporters, manufacturers, storage facilities and/or persons handling regulated hazardous materials must contact the LSP Hotline immediately to report an incident.
Hazardous Materials
Through Act 83 of the 1979 Legislative session, the Department of Public Safety, Office of State Police was authorized to promulgate rules and regulations and to oversee compliance governing the transportation, storage and manufacturing of hazardous materials in Louisiana. The legislation specifically directed the Louisiana State Police to provide emergency response to chemical emergencies at industrial sites or sites related to transportation throughout the state. With this statute, the LSP was provided statutory authority as the on-scene coordinator for all hazardous material incidents in Louisiana.
Laws passed by the legislature also required manufacturers and storage facilities to report any releases of hazardous materials into the environment. The LSP was subsequently tasked with enforcing criminal and civil infractions of the laws regarding hazardous material releases.

Explosives Control
In 1970, the Legislature passed Louisiana’s first laws governing explosives. Consequently, the State Police Explosive Control Unit was formed in 1971. Under the newly written laws, the Department of Public Safety and Corrections, Office of State Police was now tasked with regulating, both criminally and civilly, the explosives industry throughout the state of Louisiana. The Louisiana State Police was now the only state police agency in the country with regulatory authority over the explosives industry. Shortly thereafter, several states followed the path paved by the Louisiana State Police.

Right-To-Know (RTK), Tier II
Act 435 of the 1985 legislative session established the RTK laws whereby owners and operators are responsible for filing inventory forms for all hazardous materials manufactured, used, or stored at their facilities and for immediately reporting releases of certain hazardous materials in certain reportable quantities to the Louisiana State Police, Hazardous Materials Unit.
In October of 1986, the Federal Government enacted the “Emergency Planning and Community Right-To-Know Act” under SARA Title III. The formation of SARA Title III, a complex federal law with a simple purpose to protect lives and property by enabling all segments of the community to have access to timely detailed information about hazardous material in their community and use that information to plan for potential chemical emergencies. These efforts lead to the formation of the Department’s “Right-to-Know” Section. RTK currently maintains records in a data base known as the “Tier II” data base. Tier II is a comprehensive information system containing specific data regarding both the presence and location of hazardous materials in Louisiana.
