  1. What is the required minimum thickness of secondary containment for a diked area surrounding aboveground oil storage tanks under SPCC regulations?

    Answer: The containment must hold 110% of the largest tank volume

    SPCC regulations require secondary containment sized to hold the entire contents of the largest single tank plus freeboard, which is commonly interpreted as 110% of the largest tank's capacity.

  2. Under OSHA's Process Safety Management (PSM) standard, which threshold quantity of chlorine in a piping system triggers full PSM compliance?

    Answer: 1,500 pounds

    Chlorine has a PSM threshold quantity of 1,500 pounds; facilities that process, handle, or store chlorine at or above this amount must comply with OSHA's PSM standard (29 CFR 1910.119).

  3. Which record must be maintained for at least three years by a technician who purchases refrigerant for use in EPA Section 608-regulated equipment?

  4. When a steamfitter contractor generates more than 220 pounds of hazardous waste per month at a job site, what generator category applies under RCRA?

    Answer: Small Quantity Generator (SQG)

    Generators producing between 220 and 2,200 pounds (100–1,000 kg) of hazardous waste per month are classified as Small Quantity Generators (SQGs) with specific storage time and manifest requirements.

  5. A steamfitter must dispose of spent flux and solder waste containing lead from a plumbing retrofit. What is the FIRST step to determine proper disposal?

    Answer: Conduct or obtain a TCLP (Toxicity Characteristic Leaching Procedure) test to characterize the waste

    Before disposing of any potentially hazardous waste, RCRA requires generators to characterize the waste, typically using a TCLP test to determine whether lead leaches above regulatory thresholds.

  6. Which provision of the Clean Air Act requires facilities with large steam boilers to obtain an operating permit and comply with emission limits for NOx, SO2, and particulate matter?

    Answer: Title V — Operating Permits Program

    Title V of the Clean Air Act requires major sources of air pollution, including facilities with large industrial boilers, to obtain a federally enforceable operating permit that consolidates all applicable air quality requirements.

  7. Under what circumstance is a steamfitter legally permitted to intentionally vent refrigerant from a system to the atmosphere?

    Answer: Intentional venting of any regulated refrigerant is never permitted under EPA Section 608

    EPA Section 608 prohibits the knowing release of any class I or class II refrigerant or substitute refrigerant during the maintenance, service, repair, or disposal of refrigeration equipment.
