Natrona County Local Emergency Planning Committee

• Natrona County Hazardous Materials Emergency Response Plan - Available to first responders and to the public, this plan outlines roles and responsibilities during hazardous materials incidents in Natrona County.
• Emergency Response Guidebook (ERG) - The "orange book" carried by first responders.  Designed to give quick information on what to do during the first 30 minutes of a hazardous materials incident.  Has a PDF, computer, and mobile versions.  Printed copies are available for first responders through Natrona County Emergency Management.
• Wireless Information System for Emergency Responders (WISER) - Both a download and web tool for computers and mobile devices.  Combines several different hazardous materials tools, including searching for chemicals by symptom.

If you are the owner/operator of a facility in Natrona County, WY that stores more than 10,000lbs of hazardous substances, or lower quantities of Extremely Hazardous Substances (EHS), you are required by EPCRA to report annually to the Natrona County LEPC using a Tier II Report.  Reports must be received by March 1st of each year to report on substances stored in the previous calendar year.  Natrona County LEPC only accepts electronic Tier II reports produced from the EPA's Tier2 Submit software program, which can be downloaded here.  Reports should be submitted to the Wyoming SERC through the Aristatek web portal.  Learn more about EPCRA, Tier II Reporting, and find the EPA's "List of Lists" containing all designated hazardous materials and EHS here.

EPCRA Section 304 requires facilities to report hazardous materials spills over certain threshold quantities to their LEPC, State Emergency Response Commission (SERC), and the National Response Center (NRC). Facilities having a hazardous materials spill that are required to report should do the following:

1.  IMMEDIATELY DIAL 9-1-1 to inform emergency responders of the situation and enact your facility emergency plan.

2.  Work with emergency responders to safely contain the situation.

3.  AS SOON AS POSSIBLE notify the Natrona County LEPC by calling 307-235-9205 of the spill and provide the following information:

• The chemical name
• An indication of whether the substance is extremely hazardous
• An estimate of the quantity released into the environment
• The time and duration of the release
• Whether the release occurred into air, water, and/or land
• Any known or anticipated acute or chronic health risks associated with the emergency, and where necessary, advice regarding medical attention for exposed individuals
• Proper precautions, such as evacuation or sheltering in place
• Name and telephone number of contact person

4.  When practical, notify the State Emergency Response Commission (SERC) of the spill at 307-777-4900.

5.  If the hazardous material released is a CERCLA chemical and meets release thresholds, contact the National Response Center (NRC) at (800) 424-8802.
