Free Environmental Compliance Inspector Hazardous Waste Management Questions and Answers

Question 1

A Large Quantity Generator (LQG) accumulates hazardous waste in a satellite accumulation area (SAA). The container of non-acute hazardous waste becomes full, reaching the 55-gallon limit. According to 40 CFR 262.15, what is the maximum time allowed for the generator to move this full container to the central accumulation area?

Accepted Answer

Within 3 consecutive calendar days of being filled.

Answer

According to RCRA regulations at 40 CFR 262.15(a)(6), once a satellite accumulation container is full (i.e., reaches the 55-gallon limit for non-acute waste), the generator must mark it with the date it becomes full. The container must then be moved to the central accumulation area (e.g., a 90-day area for an LQG) within three consecutive calendar days.

Question 2

An inspector is reviewing a facility's hazardous waste program and notes that several types of waste are being managed under the Universal Waste Rule (40 CFR Part 273). Which of the following items is NOT federally regulated as a universal waste?

Accepted Answer

Spent lead-acid batteries being sent for reclamation.

Answer

While batteries are a category of universal waste, spent lead-acid batteries that are being reclaimed are managed under a different set of regulations, specifically 40 CFR Part 266, Subpart G. The other items—recalled pesticides, lamps, and mercury-containing equipment—are all specifically identified as categories of universal waste under the federal rules in 40 CFR Part 273.

Question 3

The Land Disposal Restrictions (LDR) program, found in 40 CFR Part 268, establishes three key prohibitions. Which of the following is one of these fundamental prohibitions?

Accepted Answer

The dilution prohibition, which prevents adding soil or water to meet a treatment standard.

Answer

The LDR program is built on three core prohibitions: the disposal prohibition (untreated waste cannot be land disposed), the storage prohibition (waste cannot be stored indefinitely to avoid treatment), and the dilution prohibition. The dilution prohibition (40 CFR 268.3) specifically forbids diluting hazardous waste as a substitute for adequate treatment.

Question 4

A Small Quantity Generator (SQG) has not received a signed copy of the hazardous waste manifest from the designated Treatment, Storage, and Disposal Facility (TSDF) within the expected timeframe. What is the generator's responsibility under RCRA?

Accepted Answer

Contact the transporter and/or the TSDF to determine the waste's status.

Answer

Under 40 CFR 262.42(a), if a Small Quantity Generator (SQG) does not receive a signed copy of the manifest from the TSDF within 60 days of the date the waste was accepted by the initial transporter, the SQG must submit a legible copy of the manifest and a letter explaining the efforts taken to locate the shipment. The first step in this process is to contact the transporter and the TSDF to investigate the status. A Large Quantity Generator (LQG) has a shorter timeframe of 45 days to take this action.

Question 5

A facility mixes used oil with a small amount of a solvent that is a characteristic hazardous waste for ignitability (D001) only. The resulting mixture is no longer ignitable. How must this mixture be managed?

Accepted Answer

As used oil, provided it is destined for recycling.

Answer

According to 40 CFR 279.10(b)(2)(iii), a mixture of used oil and a hazardous waste that is listed solely for the characteristic of ignitability (D001) can be managed as used oil, provided the resulting mixture is not ignitable. This is an important exception to the general rule that mixing used oil with hazardous waste makes the entire volume a hazardous waste. The regulations for used oil are generally less stringent than for hazardous waste.
