  1. Under the Emergency Planning and Community Right-to-Know Act (EPCRA), what threshold quantity of an extremely hazardous substance triggers Tier II reporting?

    Answer: Above the substance-specific threshold planning quantity (TPQ) or 500 lbs, whichever is less

    EPCRA Section 312 Tier II reporting is triggered when an extremely hazardous substance is present in quantities at or above 500 lbs or the threshold planning quantity (TPQ), whichever is lower.

  2. Which labeling element is NOT required on a GHS-compliant lubricant container label under OSHA's HazCom 2012 standard?

    Answer: Manufacturer's production lot number

    GHS/HazCom 2012 requires signal words, pictograms, hazard statements, precautionary statements, product identifier, and supplier information — but not the production lot number.

  3. What is the storage time limit for hazardous waste at a Small Quantity Generator (SQG) facility before the waste must be sent to a permitted facility?

    Answer: 180 days

    SQGs may accumulate hazardous waste on-site for up to 180 days (270 days if the nearest permitted facility is more than 200 miles away) without a storage permit.

  4. A plant uses a chlorinated solvent-based parts washer fluid that is also used as a metalworking lubricant. Under which EPA regulation would the used fluid most likely be regulated?

    Answer: 40 CFR Part 261 (Hazardous Waste Identification)

    Chlorinated solvent waste is typically listed as hazardous waste (F002 list) under 40 CFR Part 261, and mixing it with used oil may cause the mixture to be regulated as hazardous waste rather than used oil.

  5. Which standard provides internationally recognized guidelines for biodegradability and aquatic toxicity testing of lubricants and base oils?

    Answer: OECD 301B and OECD 202/203

    OECD 301B (Ready Biodegradability — CO2 Evolution Test) and OECD 202/203 (Aquatic Toxicity) are internationally accepted methods for assessing lubricant environmental fate and effects.

  6. Under the Clean Water Act's NPDES permit program, which lubricant-related discharge is most likely to require a specific permit condition?

    Answer: Stormwater runoff from an area where lubricants are stored or handled

    Stormwater discharges from industrial facilities — including areas where lubricants are stored or used — are regulated under NPDES industrial stormwater general permits.

  7. What is the key regulatory distinction between 'used oil' and 'used oil that has been mixed with hazardous waste' under RCRA?

    Answer: Used oil mixed with listed hazardous waste is presumed to be hazardous waste unless tested otherwise

    Under the used oil mixture rule (40 CFR 279.10), used oil mixed with a listed hazardous waste is presumed to exhibit hazardous characteristics and is subject to full hazardous waste regulations.
