Title: Emergency Planning and Community Right-to-Know Act: Modification to the Threshold Planning Quantity Methodology for the Extremely Hazardous Substances That are Solids in Solution. 
Abstract: EPA is considering an alternative approach for the threshold planning quantity (TPQ) for chemicals on the Extremely Hazardous Substances (EHS) List that are handled as solids in solution. The current TPQ for solids in solution is based on the assumption that the entire quantity of the solid chemical at a facility could potentially be released to air in event of an accident. EPA will propose a rule that would revise the TPQ for solids in solution and seek comment on an alternative approach. EPA is pursuing this proposal in part based on industry's request to revisit the TPQ rationale for the chemical paraquat dichloride (handled as a solid in aqueous solution). If the TPQ for solids in solution is raised, it would result in relieving some facilities (number and type unknown at this time) from the regulatory emergency planning and notification requirements under section 302 to 304 of the Emergency Planning and Community Right-to-Know Act (EPCRA). EPA intends to evaluate various experimental data for accidental air releases of solutions containing solid chemicals when developing revised TPQs. EPA would also seek public comment on the appropriateness of considering aerosol size as a factor for potential off-site exposure to communities.
