community right-to-know reporting (Sections 311 and 312) toxic chemical release reporting (Section 313) Under the emergency planning sections of EPCRA, facilities must identify whether there are Extremely Hazardous Substances (EHSs) present on site. A list of EHSs is provided in 40CFR Part 355 and also in Appendix F of this Response Plan. For each EHS there is a threshold planning quantity (TPQ). If facilities have greater than a TPQ of an EHS present on site, they must notify the Local Emergency Planning Committee (LEPC). Upon review of existing information for the Yankee Gulch Project, this EPCRA requirement will apply only to sulfuric acid. The TPQ for sulfuric acid is 1,000 pounds, which equates to about 65 gallons (assuming a density of 15.35 pounds per gallon). American Soda plans to store approximately two 55-gallon drums (110 gallons) of sulfuric acid at the Parachute Site. Another EHS that could be present at both sites is cyclohexylamine. It is a minor ingredient in one of the boiler feed water treatment chemicals. cyclohexylamine will not be present in levels above the TPQ, which is 10,000 pounds. An EHS review will be performed again prior to startup. If a regulated chemical is released into the environment at a level greater than the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA)- defined Reportable Quantity (RQ), the facility must notify the appropriate regulatory agencies as required by EPCRAs emergency notification section. The list in Appendix F also contains RQ values. Therefore, if American Soda has a sulfuric acid spill of greater than the RQ of 65 gallons (which is also the TPQ), notification must be made to applicable regulatory agencies. The RQ of cyclohexylamine is 1 pound (which is much less than the TPQ), which equates to 4,055 gallons of the boiler feed water treatment chemical. Since only two 280-gallon totes (560 gallons) of the chemical will be on site, the RQ cannot be exceeded. Several components of unleaded gasoline and diesel fuel also have regulated RQs. Releases of these chemicals above the RQ would also be reportable. Under Section 311, facilities must provide either a list of OSHA Hazardous Chemicals or copies of Hazardous Chemical MSDSs to the LEPC. Under Section 312, facilities must complete annual inventory reports (Title III, Tier I or Tier fI reports) that identify OSHA hazardous chemical storage quantities, conditions, and locations. The reporting threshold for the inventory report is 500 pounds for EHSs and 10,000 pounds for other OSHA hazardous chemicals. These are the right-to-know requirements of EPCRA. America Soda will submit their OSHA hazardous chemical list or copies of MSDSs to the LEPC for each site prior to startup. American Soda will be required to file the Tier I or Tier I[ report for at least sulfuric acid, sodium carbonate, and sodium bicarbonate. Reports are due each March 1 for the previous calendar year. Amore comprehensive review of material storage information will be performed prior to startup.
