Correct answer: C. 270 days

40 CFR 262.16 extends the standard 180-day SQG accumulation limit to 270 days when the generator must transport its waste a distance of 200 miles or more.

• A: 90 days is the standard LQG accumulation limit, not the extended SQG limit for long-distance shipments.
• B: 180 days is the standard SQG accumulation limit for shipments under 200 miles, not the extended limit.
• D: 365 days is not a recognized RCRA accumulation time limit for SQGs under any circumstance.

Correct answer: B. Missouri has been authorized by EPA to administer RCRA under its own state program

Under RCRA, EPA may authorize a state to administer its own hazardous waste program in lieu of the federal program, and Missouri has received this authorization, with the Missouri Department of Natural Resources (MDNR) as the implementing agency.

• A: No state is exempt from RCRA; the federal program still applies as a baseline that authorized state programs must meet or exceed.
• C: RCRA is a federal law that applies nationwide regardless of geography; there is no such east/west limitation.
• D: States cannot unilaterally opt out of federal environmental law; authorization is a formal EPA process, not a state's own choice to disregard federal law.

Correct answer: B. Incorporate and mirror federal 40 CFR standards, with Missouri-specific citations and any state additions

10 CSR 25 incorporates the federal 40 CFR Parts 260-279 framework by reference (with Missouri-specific numbering) and administers it through MDNR, sometimes adding state-specific provisions.

• A: An EPA-authorized state program must be at least as stringent as the federal program; it does not simply replace federal substance with unrelated state-only rules.
• C: The regulations apply broadly to hazardous waste generators, transporters, and treatment/storage/disposal facilities operating in Missouri, not only to federal grant recipients.
• D: Household hazardous waste is generally exempt from RCRA generator regulation; 10 CSR 25 governs regulated hazardous waste from businesses and institutions, not household waste.

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

Under 40 CFR 262.13, a generator producing under 100 kg of non-acute and under 1 kg of acute hazardous waste per month qualifies as a Very Small Quantity Generator (VSQG).

• A: LQGs generate more than 1,000 kg of non-acute hazardous waste per month, far above this generator's volume.
• B: SQGs generate between 100 and 1,000 kg of non-acute hazardous waste per month, above this generator's stated volume.
• D: VSQGs still have regulatory obligations, including ensuring waste is sent to an authorized facility; they are not entirely unregulated.

Correct answer: B. Small Quantity Generator (SQG)

SQGs generate more than 100 kg but less than 1,000 kg of non-acute hazardous waste per calendar month, which fits this facility's 400 kg output.

• A: VSQG status applies only below 100 kg per month; 400 kg exceeds that threshold.
• C: LQG status begins at 1,000 kg per month of non-acute hazardous waste; 400 kg is well below that threshold.
• D: A generator producing 400 kg per month is squarely within RCRA's regulatory scope as an SQG, subject to specific accumulation and management standards.
