Tier I information may be obtained from state emergency response commissions or local emergency planning committees during normal working hours.
Tier II information for a specific chemical at a facility may be obtained by sending a written request to the state emergency response commission or the local emergency planning committee. If they do not have the requested Tier II information, they must obtain it from the facility. For chemicals present below 10,000 pounds, the response is discretionary by either the state emergency response commission or the local emergency planning committee and depends on the justification of need by the requestor. The facility must make the information available to the SERC or LEPC if they request it on behalf of the individual.
