CEA Risk Management & Environmental Impact 2

Question 1

Which risk assessment methodology uses a matrix combining likelihood and consequence ratings to prioritize environmental risks?

Accepted Answer

Risk Ranking Matrix

Answer

A Risk Ranking Matrix plots likelihood against consequence severity to assign priority scores, enabling auditors to focus on high-risk environmental issues first.

Question 2

Under RCRA, which characteristic makes a solid waste a hazardous waste due to its potential to cause an explosion or fire?

Accepted Answer

Ignitability

Answer

Ignitability (D001) is the RCRA characteristic applied to wastes that can catch fire under standard conditions, posing fire and explosion risks.

Question 3

An environmental auditor identifies that stormwater runoff from an industrial site is discharging to a wetland without an NPDES permit. What is the FIRST corrective action priority?

Accepted Answer

Cease or control the discharge and notify the regulatory agency

Answer

Stopping an unpermitted discharge and notifying regulators is the immediate legal obligation to prevent ongoing Clean Water Act violations and demonstrate good faith.

Question 4

Which concept describes the maximum concentration of a pollutant in air that a healthy adult can be exposed to for a lifetime without appreciable health risk?

Accepted Answer

Reference Concentration (RfC)

Answer

The Reference Concentration (RfC) is EPA's estimate of a continuous inhalation exposure level likely to be without risk of deleterious effects over a lifetime.

Question 5

A brownfield site risk assessment reveals arsenic soil concentrations above residential but below commercial screening levels. What risk management option is MOST appropriate if the site will become a parking lot?

Accepted Answer

No action required since concentrations are below commercial levels

Answer

If concentrations fall below the applicable commercial/industrial screening level for the intended land use, the risk is considered acceptable and no remediation is required.
