HSE Environmental Compliance and Protection 4

Question 1

Which federal law requires manufacturers and importers to evaluate and report risks associated with new chemical substances before they are introduced to commerce?

Accepted Answer

TSCA

Answer

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.

Question 2

Under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), what must occur before a pesticide can be legally sold or distributed in the US?

Accepted Answer

It must be registered with the EPA and bear an EPA registration number

Answer

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.

Question 3

What is the environmental significance of the 'mixing bowl' rule under RCRA?

Accepted Answer

Any mixture of a listed hazardous waste with another solid waste is considered hazardous waste

Answer

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.

Question 4

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?

Accepted Answer

Clean Water Act pretreatment standards

Answer

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.

Question 5

Which of the following scenarios would most likely trigger the need for an Environmental Impact Statement (EIS) under NEPA?

Accepted Answer

A federal agency granting a permit for a major highway construction project through wetlands

Answer

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.'
