With regard to thresholds in mixtures, how is reporting under Sections 311 and 312 handled if a facility has a number of different mixtures on-site and each is under 10,000 pounds but the mixtures contains an aggregated quantity of an extremely hazardous substance (EHS) that exceeds its reporting threshold? If…
If a facility purchases more than 10,000 pounds of a hazardous chemical for which OSHA requires an MSDS in a calendar year but never actually receives or stores more than the 10,000 pound threshold at one time, must the facility report under EPCRA Sections 311 and 312? The MSDS and…
The definition of "facility" for EPCRA Sections 311 and 312 does not include "motor vehicles, rolling stock and aircraft." Do hazardous chemicals present in cars, trucks, forklifts and other vehicles need to be considered for Sections 311 and 312 reporting as present in the "facility?" Hazardous chemicals present in vehicles…
Do you apply the whole weight of an acid mixture towards the threshold under EPCRA Sections 311 and 312 or just the percentage of acid stated on the material safety data sheet (MSDS)? Aqueous acids are considered mixtures under EPCRA Sections 311 and 312. The acid itself is the hazardous…
Why does EPA recommend submitting a list rather than Material Safety Data Sheets (MSDS) to meet the requirements of Section 311? Lists will minimize the paperwork burden for state and local governments and local fire departments. In addition, the list can be used as an index to inventory forms required…
A facility storing hazardous chemicals on site permanently ceases operations and notifies the State Emergency Response Commission (SERC). Since the facility will no longer be in operation on March 1 of the following year, must the owner/operator of the closed facility submit a Tier I or Tier II hazardous chemical…
What determines whether a "Regulatory Synonym" is listed for a substance in Table 302.4 of 40 CFR 302.4? In general, no entry is made in the "Regulatory Synonym" column of 40 CFR 302.4, Table 302.4 for a substance if only one chemical name is used to identify that substance under…
Can the "de minimis" concept used in determining the threshold planning quantities in mixtures be applied in the determination of the reportable quantity for emergency release notification? No. The "de minimis" quantity was set in place for threshold planning quantities simply to make the calculation of the total amount of…
What is the relationship between CERCLA hazardous substances and the U.S. Department of Transportation's (DOT) Hazardous Materials Regulations? CERCLA section 306(a), as amended, requires the DOT to list and regulate as hazardous materials all CERCLA hazardous substances. Thus, all CERCLA hazardous substances are covered by the DOT's Hazardous Materials Regulations…
How is the term "release" defined? CERCLA section 101(22) defines "release" as any "...spilling, leaking, pumping, pouring, emitting, emptying, discharging, injecting, escaping, leaching, dumping, or disposing into the environment (including the abandonment or discarding of barrels, containers, and other closed receptacles containing any hazardous substance or pollutant or contaminant)...."
Section 304 covers all releases of listed hazardous or extremely hazardous substances, including those involved in transportation in excess of the reportable quantity (RQ). Owners or operators of transportation facilities may call 911 or the local telephone operator, in order to satisfy Section 304 notification requirements when a release occurs…
A medical facility uses liquid nitrogen for the nuclear magnetic resonance spectrometer. The spectrometer is used for medical diagnostic purposes. In addition, the facility is required by the Occupational Safety and Health Administration (OSHA) to have a material safety data sheet (MSDS) available for the liquid nitrogen. Is the liquid…
Is there a concentration cutoff below which it is not necessary to report a release, even though a Reportable Quantity (RQ) might have been exceeded over a 24-hour period? No. There are no concentration cutoffs for the RQs (i.e., a lower-bound concentration below which reporting would not be required). Unless…
Would disposal of a hazardous substance into a Resource Conservation and Recovery Act (RCRA) Subtitle C permitted facility or interim status facility be reportable? No. The disposal of hazardous substances into a disposal facility in accordance with EPA regulations is not subject to CERCLA notification provisions. Where the disposal of…
