FREE Environmental Compliance Inspector Federal Environmental Regulations Questions and Answers

Question 1

Under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), who must be notified immediately if a facility releases a hazardous substance in an amount equal to or greater than its Reportable Quantity (RQ)?

Accepted Answer

The National Response Center (NRC)

Answer

CERCLA Section 103(a) requires that the person in charge of a facility must immediately notify the National Response Center (NRC) as soon as they have knowledge of a release of a CERCLA hazardous substance in a quantity that equals or exceeds its RQ within a 24-hour period. While the SERC and local authorities are notified under EPCRA, the initial federal notification for a CERCLA release goes to the NRC.

Question 2

A facility generates 1,200 kg of non-acute hazardous waste and 0.5 kg of acutely hazardous waste in a calendar month. Under the Resource Conservation and Recovery Act (RCRA), how would this facility be classified?

Accepted Answer

Large Quantity Generator (LQG)

Answer

A facility is classified as a Large Quantity Generator (LQG) if it generates 1,000 kg or more of non-acute hazardous waste per month OR more than 1 kg of acutely hazardous waste per month. Since this facility generates over 1,000 kg of non-acute hazardous waste, it falls into the LQG category, which has the most stringent regulatory requirements.

Question 3

An inspector is reviewing a manufacturing plant's obligations under the Clean Air Act (CAA). The plant is planning a modification that will significantly increase its emissions of a regulated pollutant. Which CAA program is specifically designed to set technology-based emission standards for such new or modified stationary sources?

Accepted Answer

New Source Performance Standards (NSPS)

Answer

The New Source Performance Standards (NSPS) program, established under Section 111 of the Clean Air Act, sets nationally uniform, technology-based emission standards for new, modified, and reconstructed stationary sources. The goal is to ensure that new sources of pollution incorporate the best demonstrated control technologies.

Question 4

A facility that stores 12,000 pounds of a hazardous chemical (that is not an Extremely Hazardous Substance) is required to submit a Tier II form by March 1st each year. Which federal regulation mandates this reporting?

Accepted Answer

Emergency Planning and Community Right-to-Know Act (EPCRA)

Answer

The Emergency Planning and Community Right-to-Know Act (EPCRA) Section 312 requires facilities that store hazardous chemicals above certain thresholds to submit an annual Tier II inventory form. The threshold for most hazardous chemicals is 10,000 pounds. These reports are submitted to the SERC, LEPC, and local fire department to aid in emergency planning.

Question 5

Which of the following activities would most likely require a National Pollutant Discharge Elimination System (NPDES) permit under the Clean Water Act?

Accepted Answer

A manufacturing facility discharging treated wastewater from a pipe directly into a river

Answer

The Clean Water Act's NPDES program regulates discharges of pollutants from a point source (like a pipe) into waters of the United States. A manufacturing facility discharging directly to a river is a classic example of a point source discharge requiring an NPDES permit. Discharges to a POTW are regulated under pretreatment standards, and construction activities generally require a permit only if they disturb one or more acres.
