Missoula County maintains a listing of businesses that handle and store potentially hazardous chemicals. This inventory is kept in accordance with Environmental Planning and Community Right-To-Know Act (EPCRA), commonly known as SARA Title III, Tier II. Tier II reporting applies to any facility at which a hazardous chemical, as defined by the Occupational Safety and Health Act, is present in an amount exceeding a specified threshold.  Federal regulations have established reporting requirements of hazardous chemicals to enhance community awareness of chemical hazards and to help develop state and community emergency response plans. The Missoula LEPC asks facilities to voluntarily report chemical storage below federal reporting requirements.

Facilities within Missoula County that handle or store hazardous materials are strongly encouraged to use E-Plan as their basic Tier 2 reporting methodology.

As an alternative, paper forms may be completed using the Tier II Emergency and Hazardous Chemical Inventory Form. This list is maintained through the Local Emergency Planning Committee (LEPC), businesses reporting these materials can click here to email the Office of Emergency Management or can call (406) 258-3631. 

Further guidance and information can be found on the EPA's EPCRA website. Other comprehensive websites that provide additional chemical right-to-know information for Missoula County include Scorecard and RTK Net.
