CLS Regulatory Compliance & Legal Framework 2 — Questions and Answers
Question 1: Under the Clean Air Act, which type of lubricant additive is most closely regulated due to its contribution to hazardous air pollutants?
- Zinc dialkyldithiophosphate (ZDDP) (Correct answer)
- Polyalphaolefin base stocks
- Ester-based synthetic fluids
- Hydrocracked Group II base oils
Correct answer: Zinc dialkyldithiophosphate (ZDDP)
ZDDP contains phosphorus and sulfur compounds that can form hazardous combustion byproducts, making it subject to scrutiny under the Clean Air Act.
Question 2: Which U.S. agency enforces the Toxic Substances Control Act (TSCA) regulations that affect lubricant chemical inventories?
- OSHA
- EPA (Correct answer)
- DOT
- CPSC
Correct answer: EPA
The Environmental Protection Agency (EPA) administers and enforces TSCA, which requires chemical substances used in lubricants to be listed on the TSCA inventory.
Question 3: A lubrication specialist discovers a used oil storage tank is leaking onto soil. Under CERCLA, who may be held liable for cleanup costs?
- Only the current property owner
- Only the original polluter
- Any potentially responsible party including current owners, past owners, and generators (Correct answer)
- Only the lubricant manufacturer
Correct answer: Any potentially responsible party including current owners, past owners, and generators
CERCLA imposes joint and several liability on all potentially responsible parties (PRPs), which can include current owners, past owners, operators, and waste generators.
Question 4: What is the minimum federal used oil recycling standard that processors must meet under 40 CFR Part 279?
- Used oil must be re-refined to virgin oil quality
- Used oil must be burned for energy recovery only
- Used oil must meet specification limits for flash point, total halogens, and arsenic/lead/chromium (Correct answer)
- Used oil must be rendered non-hazardous before transport
Correct answer: Used oil must meet specification limits for flash point, total halogens, and arsenic/lead/chromium
40 CFR Part 279 defines on-specification used oil by setting limits on flash point (≥100°F), total halogens (≤4,000 ppm), and metals such as arsenic, cadmium, chromium, and lead.
Question 5: Which OSHA standard specifically governs worker exposure to mineral oil mist in machining and metalworking operations?
- 29 CFR 1910.119 (PSM)
- 29 CFR 1910.1000 (Air Contaminants) (Correct answer)
- 29 CFR 1910.132 (PPE)
- 29 CFR 1910.147 (Lockout/Tagout)
Correct answer: 29 CFR 1910.1000 (Air Contaminants)
OSHA's 29 CFR 1910.1000 Air Contaminants standard establishes the permissible exposure limit (PEL) of 5 mg/m³ for mineral oil mist as a ceiling value.
Question 6: When transporting used oil classified as a hazardous waste by a state but not federally, which set of regulations takes precedence?
- Federal DOT hazmat rules always override state rules
- The more stringent of the two regulatory schemes applies (Correct answer)
- State rules are invalid if they conflict with federal rules
- Only the destination state's rules apply
Correct answer: The more stringent of the two regulatory schemes applies
Under the principle of cooperative federalism, states may adopt standards more stringent than federal requirements, and the more protective rules apply to operations within that state.
Question 7: Which document must accompany a shipment of hazardous waste lubricant from a generator to a licensed disposal facility?
- Bill of lading
- Safety data sheet only
- Uniform Hazardous Waste Manifest (Correct answer)
- Certificate of analysis
Correct answer: Uniform Hazardous Waste Manifest
The Uniform Hazardous Waste Manifest is required by RCRA to track hazardous waste from its point of generation to final disposal ('cradle-to-grave' tracking).
