Under California's Generator Improvements Rule adoption (22 CCR §66262.13, effective July 1, 2024), what monthly non-acute hazardous waste generation threshold moves a generator from Very Small Quantity Generator (VSQG) into the Small Quantity Generator (SQG) category?
A. 220 kg or more per calendar month
B. 100 kg or more per calendar month
C. 1,000 kg or more per calendar month
D. 2,200 kg or more per calendar month
Show answer and reasoning
Correct answer: B. 100 kg or more per calendar month
- A: 220 kg/month is not a category breakpoint used in the CA table.
- C: 1,000 kg or more is the LQG threshold, not the VSQG/SQG boundary.
- D: 2,200 kg has no role in the generator-category table.

California's July 2024 hazardous waste regulation update formally adopted the federal term 'Very Small Quantity Generator (VSQG)' in place of the older state term. What is the single most important practical consequence of this change, as clarified by DTSC's FAQ?
A. California VSQGs are now fully exempt from all hazardous waste regulation, matching the federal conditional exemption exactly
B. The change eliminated the SQG category entirely and merged it into VSQG
C. California VSQGs must still comply with Small Quantity Generator (SQG)-level requirements, because California's program does not include the federal VSQG conditions for exemption
D. The change only affects household hazardous waste collection facilities and has no effect on businesses
Show answer and reasoning
Correct answer: C. California VSQGs must still comply with Small Quantity Generator (SQG)-level requirements, because California's program does not include the federal VSQG conditions for exemption
- A: DTSC's FAQ explicitly states California did not adopt the federal conditions for exemption for VSQGs.
- B: SQG remains a distinct, defined category under 22 CCR §66262.13.
- D: The FAQ addresses generator obligations broadly, not just household facilities.

A facility in Ohio and an identical facility in California each generate 90 kg of non-acute hazardous waste in a month, qualifying both as VSQGs by weight. How does their federal-versus-California regulatory burden differ?
A. Both facilities face identical requirements because RCRA is a federally delegated program that CA cannot modify
B. The California facility has fewer requirements because state programs must always be less stringent than federal minimums
C. The Ohio facility has more requirements because Ohio never adopted VSQG rules
D. The Ohio facility can operate under the federal VSQG conditional exemption (40 CFR §262.14) with minimal requirements; the California facility must still meet SQG-level accumulation, labeling, and other requirements because California did not adopt the federal exemption conditions
Show answer and reasoning
Correct answer: D. The Ohio facility can operate under the federal VSQG conditional exemption (40 CFR §262.14) with minimal requirements; the California facility must still meet SQG-level accumulation, labeling, and other requirements because California did not adopt the federal exemption conditions
- A: States may be more stringent than federal RCRA minimums, which is exactly what California did here.
- B: States can never be less stringent than the federal floor under RCRA authorization.
- C: Ohio, like nearly all states, follows the federal VSQG conditional exemption.

Under 22 CCR §66262.16, what is the maximum quantity of hazardous waste a California Small Quantity Generator may accumulate onsite at any time without a permit?
A. 6,000 kilograms (13,200 pounds)
B. 1,000 kilograms (2,200 pounds)
C. 100 kilograms (220 pounds)
D. 13,200 kilograms (29,000 pounds)
Show answer and reasoning
Correct answer: A. 6,000 kilograms (13,200 pounds)
- B: 1,000 kg/month is the generation threshold that defines LQG status, not the SQG accumulation cap.
- C: 100 kg/month is the VSQG generation threshold, not an accumulation cap.
- D: 13,200 kg is not the figure in §66262.16 (13,200 lbs = 6,000 kg is the correct pairing, not kg alone).

How many days may a California Small Quantity Generator ordinarily accumulate hazardous waste onsite without a storage permit under 22 CCR §66262.16?
A. 90 days
B. 180 days
C. 365 days
D. 30 days
Show answer and reasoning
Correct answer: B. 180 days
- A: 90 days is the Large Quantity Generator (federal and CA) accumulation limit, not the SQG limit.
- C: 365 days exceeds any accumulation exemption period.
- D: 30 days is the manifest state-copy submission window, not an accumulation limit.
