Correct answer: A. Very Small Quantity Generator (VSQG), because it generates less than 100 kg (about 220 lbs) of hazardous waste per calendar month

Correct. Generator category is based on the amount of hazardous waste generated in a calendar month; less than 100 kg (about 220 lbs) per month is the VSQG threshold under 40 CFR 262.13, which applies directly in Iowa.

• B: Incorrect. SQG status begins at 100 kg (220 lbs) per month, not at any generation above zero; this facility's 150 lbs/month is below that threshold.
• C: Incorrect. LQG status is defined by generating more than 1,000 kg/month or accumulating more than 6,000 kg on-site, not by the 1,000 kg accumulation figure alone in isolation from the monthly generation rate.
• D: Incorrect. VSQGs are still regulated (waste determination, accumulation limits, disposal at an authorized facility); the category is not an exemption from all hazardous waste rules.

Correct answer: B. 180 days (or 270 days if the waste must be transported more than 200 miles to its designated facility)

Correct. SQGs may accumulate hazardous waste on-site for up to 180 days, extended to 270 days when the waste must travel more than 200 miles to its designated treatment, storage, or disposal facility.

• A: Incorrect. The 90-day limit applies to Large Quantity Generators, not SQGs.
• C: Incorrect. No generator category is allowed a full year of on-site accumulation under the standard accumulation provisions.
• D: Incorrect. SQGs are subject to a defined accumulation time limit; exceeding it without a proper extension converts the facility into a storage facility requiring a permit.

Correct answer: C. 90 days

Correct. LQGs may accumulate hazardous waste on-site for a maximum of 90 days under 40 CFR 262.17, which applies directly in Iowa because Iowa is not an EPA-authorized RCRA state.

• A: Incorrect. 270 days is the extended SQG limit for waste traveling more than 200 miles, not the LQG standard.
• B: Incorrect. 180 days is the standard SQG limit, not the LQG limit.
• D: Incorrect. 45 days is not a recognized RCRA accumulation time limit for any generator category.

Correct answer: D. Mark the container with the date the 55-gallon limit was reached and move it to a central accumulation area within 3 days

Correct. Once the satellite accumulation limit is reached, the generator has 3 days to mark the container with the date and move it to a central (main) accumulation area, where the standard 90/180/270-day accumulation clock then begins.

• A: Incorrect. On-site disposal without a manifest and without proper authorization is never permitted for hazardous waste, regardless of accumulation area type.
• B: Incorrect. Reaching the 55-gallon (or 1-quart acute) limit triggers an affirmative duty to date and move the container; simply keeping it labeled at the point of generation is not sufficient once the limit is exceeded.
• C: Incorrect. No same-day DNR notification or variance request is required for exceeding the satellite accumulation limit; the generator's obligation is procedural (dating and moving the container), not a regulatory filing.

Correct answer: A. Iowa is one of only two states (with Alaska) that has never received EPA authorization to operate its own RCRA hazardous waste program in lieu of the federal program, so EPA Region 7 directly implements and enforces the federal hazardous waste regulations in Iowa

Correct. Iowa and Alaska are the only two states that lack EPA authorization to administer the base RCRA hazardous waste program; EPA Region 7 (Kansas City/Lenexa) directly implements and enforces the federal hazardous waste regulations in Iowa, even though the Iowa DNR administers related state waste programs.

• B: Incorrect. Iowa has never received base RCRA authorization; this is the opposite of Iowa's actual status.
• C: Incorrect. There is no interstate RCRA authorization compact between Iowa and Illinois; each state's RCRA authorization status (or lack of it) is determined individually by EPA.
• D: Incorrect. Hazardous waste regulation in Iowa involves the Iowa DNR (state waste programs) and EPA Region 7 (federal RCRA enforcement), not the Iowa Department of Agriculture.
