Question 1

Under the Emergency Planning and Community Right-to-Know Act (EPCRA), Section 302 requires facilities to notify the State Emergency Response Commission (SERC) if they store:

Accepted Answer

Extremely hazardous substances at or above the threshold planning quantity (TPQ)

Answer

EPCRA Section 302 requires facilities to notify the SERC if they have extremely hazardous substances (EHS) at or above the threshold planning quantity, triggering local emergency planning requirements.

Question 2

Which regulatory program governs the cleanup of contaminated sites that are not on the National Priorities List (NPL)?

Accepted Answer

RCRA Corrective Action program

Answer

RCRA Corrective Action (Section 3004(u)) requires facilities with RCRA permits to investigate and clean up hazardous waste releases, addressing contamination at non-NPL sites.

Question 3

In the CERCLA cleanup process, which step follows the Remedial Investigation (RI) to evaluate cleanup alternatives?

Accepted Answer

Feasibility Study (FS)

Answer

After the RI characterizes site conditions, the Feasibility Study (FS) evaluates remedial alternatives against nine criteria, leading to selection of a remedy in the Record of Decision.

Question 4

The 'toxicity characteristic' under RCRA TCLP (Toxicity Characteristic Leaching Procedure) testing determines if a waste is hazardous based on:

Accepted Answer

Whether leachate concentrations exceed regulatory thresholds for listed contaminants

Answer

TCLP simulates landfill leaching conditions; if the resulting leachate exceeds regulatory limits for any of 40 listed metals or organics, the waste exhibits the toxicity characteristic.

Question 5

Which remediation technology uses injected oxidants to chemically destroy organic contaminants in groundwater in situ?

Accepted Answer

In situ chemical oxidation (ISCO)

Answer

ISCO injects oxidizing agents such as permanganate, persulfate, or hydrogen peroxide directly into the subsurface to chemically destroy contaminants like chlorinated solvents and petroleum hydrocarbons.
