Correct answer: A. Corrosivity

Correct. Corrosivity is generally evaluated in part through pH: an aqueous waste with a pH less than or equal to 2, or greater than or equal to 12.5, generally meets the corrosivity characteristic under the RCRA-based framework.

• B: Incorrect. Reactivity concerns properties such as instability, water reactivity, or the tendency to generate toxic gases, not pH level.
• C: Incorrect. Toxicity is generally evaluated through a specific leaching test (the Toxicity Characteristic Leaching Procedure) for specific contaminants, not through pH alone.
• D: Incorrect. Ignitability concerns flash point and related flammability properties, not pH level.

Correct answer: D. Ignitability

Correct. Ignitability is one of the four recognized hazardous waste characteristics under the RCRA-based framework (along with corrosivity, reactivity, and toxicity), used to determine whether a solid waste is a characteristic hazardous waste.

• A: Incorrect. Palatability (taste-related) is not a recognized RCRA hazardous waste characteristic.
• B: Incorrect. Marketability (commercial value) is not a recognized RCRA hazardous waste characteristic.
• C: Incorrect. Portability (ease of transport) is not a recognized RCRA hazardous waste characteristic.

Correct answer: A. The federal Resource Conservation and Recovery Act (RCRA) and its implementing regulations, with Minnesota-specific additions

Correct. Minn. R. chapter 7045 largely mirrors the federal Resource Conservation and Recovery Act (RCRA) hazardous waste generator framework, while adding Minnesota-specific requirements, such as its own generator licensing structure.

• B: Incorrect. The Clean Water Act addresses discharges to waters of the United States; Minnesota's hazardous waste generator rules are grounded in the RCRA framework, not the Clean Water Act.
• C: Incorrect. The Endangered Species Act addresses protection of threatened and endangered species and their habitats, unrelated to hazardous waste generator regulation.
• D: Incorrect. Minnesota's hazardous waste rules are specifically structured around, and largely mirror, the federal RCRA framework, with state-specific additions layered on top.

Correct answer: B. Very small quantity generator (VSQG)

Correct. A facility generating less than 100 kg of hazardous waste and less than 1 kg of acute hazardous waste per calendar month generally qualifies as a very small quantity generator (VSQG) under Minnesota's generator size determination rule, mirroring the federal RCRA threshold.

• A: Incorrect. SQG status applies to generators producing between 100 kg and 1,000 kg of hazardous waste per month, above the threshold described in this scenario.
• C: Incorrect. Minnesota, consistent with the federal RCRA framework, recognizes generator categories below 1,000 kg per month, including the VSQG and SQG tiers.
• D: Incorrect. LQG status applies to generators exceeding 1,000 kg of hazardous waste (or more than 1 kg of acute hazardous waste) per month, a substantially higher threshold than described here.

Correct answer: A. Small quantity generator (SQG)

Correct. A facility generating between 100 kg and 1,000 kg of hazardous waste per calendar month (with no acute hazardous waste generated above the 1 kg threshold) generally qualifies as a small quantity generator (SQG) under Minnesota's generator size determination rule.

• B: Incorrect. 400 kg per month falls below the LQG threshold of more than 1,000 kg of hazardous waste (or more than 1 kg of acute hazardous waste) per month.
• C: Incorrect. Generating 400 kg of hazardous waste per month places the facility within the SQG category with corresponding regulatory obligations; it is not an exempt quantity.
• D: Incorrect. 400 kg per month exceeds the VSQG threshold of less than 100 kg per month.
