Which federal law requires manufacturers and importers to evaluate and report risks associated with new chemical substances before they are introduced to commerce?
Answer: TSCA
The Toxic Substances Control Act (TSCA) requires pre-manufacture notification (PMN) for new chemical substances and grants EPA authority to restrict or ban chemicals that pose unreasonable risks.
Under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), what must occur before a pesticide can be legally sold or distributed in the US?
Answer: It must be registered with the EPA and bear an EPA registration number
FIFRA requires all pesticides sold or distributed in the US to be registered with EPA, which evaluates whether the pesticide can perform its intended function without unreasonable adverse effects on humans or the environment.
What is the environmental significance of the 'mixing bowl' rule under RCRA?
Answer: Any mixture of a listed hazardous waste with another solid waste is considered hazardous waste
The RCRA mixture rule states that any mixture containing a listed hazardous waste retains its hazardous waste classification, even if the listed waste is a small fraction of the total mixture.
An industrial facility's wastewater pretreatment system fails, causing an unpermitted discharge to a publicly owned treatment works (POTW). Which regulatory framework most directly governs this situation?
Answer: Clean Water Act pretreatment standards
CWA pretreatment standards under 40 CFR Part 403 regulate industrial discharges to POTWs to prevent interference with treatment operations and pass-through of pollutants to receiving waters.
Which of the following scenarios would most likely trigger the need for an Environmental Impact Statement (EIS) under NEPA?
Answer: A federal agency granting a permit for a major highway construction project through wetlands
NEPA requires an EIS for federal actions that significantly affect the quality of the human environment; a major federally permitted infrastructure project impacting wetlands would qualify as a 'major federal action significantly affecting the environment.'
What is the primary distinction between 'corrective action' under RCRA and 'remediation' under CERCLA?
Answer: RCRA corrective action addresses contamination at permitted facilities; CERCLA addresses releases at abandoned or uncontrolled hazardous waste sites
RCRA corrective action targets contamination at active, permitted treatment, storage, and disposal facilities, while CERCLA (Superfund) addresses cleanup of releases at abandoned sites and uncontrolled hazardous waste locations.
A facility stores 55-gallon drums of flammable solvent waste. According to OSHA and EPA standards, what is the minimum distance that should typically be maintained between a drum storage area and ignition sources?
Answer: 25 feet
OSHA standards (29 CFR 1910.106) and NFPA guidelines generally require that flammable liquid storage areas be located at least 25 feet from ignition sources to reduce fire and explosion risk.
