Correct answer: D. 180 days

Correct. 40 CFR 262.16(b) allows a Small Quantity Generator to accumulate hazardous waste on site for up to 180 days without a storage permit, provided applicable conditions are met (up to 270 days if waste must be transported more than 200 miles for treatment, storage, or disposal).

• A: 365 days is not the SQG accumulation limit; a full-year accumulation period is not recognized under the standard SQG exemption.
• B: 60 days is shorter than the SQG accumulation limit set by this rule.
• C: 90 days is the accumulation limit for Large Quantity Generators under 40 CFR 262.17, not Small Quantity Generators.

Correct answer: D. 40 CFR Parts 260-279 (Resource Conservation and Recovery Act hazardous waste regulations)

Correct. OAC 252:205, Oklahoma's Hazardous Waste Management chapter, incorporates the federal hazardous waste management regulations at 40 CFR Parts 260 through 279, administered by DEQ's Land Protection Division under its EPA-authorized RCRA program.

• A: Clean Water Act permitting regulations govern water discharges, not hazardous waste generator, storage, or disposal standards.
• B: OSHA's general industry standards address workplace safety, not the hazardous waste generator classification and management scheme found in RCRA.
• C: Air quality standards under 40 CFR Parts 50-99 are a Clean Air Act program, unrelated to RCRA hazardous waste management, which OAC 252:205 governs.

Correct answer: D. Very Small Quantity Generator (VSQG)

Correct. Under 40 CFR 262.13-262.14, a facility generating 100 kg or less of hazardous waste per month (and no more than 1 kg of acute hazardous waste) is classified as a Very Small Quantity Generator, formerly termed Conditionally Exempt Small Quantity Generator (CESQG).

• A: A TSDF is a facility permitted to treat, store, or dispose of hazardous waste, a distinct regulatory role from a generator classified by monthly waste volume.
• B: LQGs generate 1,000 kg/month or more of hazardous waste, or smaller amounts of acute hazardous waste; this far exceeds the 100 kg/month VSQG threshold.
• C: SQGs generate more than 100 kg but less than 1,000 kg of hazardous waste per month, above the VSQG threshold described in the question.

Correct answer: C. Greater than 100 kg but less than 1,000 kg per month

Correct. Under 40 CFR 262.16, a Small Quantity Generator generates more than 100 kg but less than 1,000 kg of hazardous waste in a calendar month.

• A: Greater than 10,000 kg per month is far above the SQG range and would place a facility well into LQG territory.
• B: Less than 1 kg per month is far below even the VSQG threshold; it does not describe the SQG range.
• D: The SQG category is a range, not a single fixed quantity; 1,000 kg/month or more actually marks the start of the LQG category, not the SQG threshold itself.

Correct answer: A. 1,000 kg or more per month, or more than 1 kg per month of acute hazardous waste

Correct. Under 40 CFR 262.17, a Large Quantity Generator generates 1,000 kg or more of hazardous waste per calendar month, or more than 1 kg per month of acute hazardous waste, or more than 100 kg per month of acute hazardous waste spill residue or contaminated soil.

• B: 5,000 kg is not the LQG threshold; the LQG category begins at 1,000 kg per month, a lower figure than this option states.
• C: 100 kg or more per month marks the boundary between VSQG and SQG status, not the LQG threshold.
• D: 500 kg per month falls within the SQG range (greater than 100 kg but less than 1,000 kg), not the LQG threshold.
