Regulatory Compliance and Standards

This domain tests whether you can map facility activities to the correct OSHA, EPA, and DOT requirements, apply quantity thresholds correctly, and meet notification and permit deadlines.

The statutory map

  • OSHA: the General Duty Clause, OSH Act Section 5(a)(1), covers recognized hazards without a specific standard. 29 CFR 1910 covers general industry, 1926 construction, 1904 recordkeeping.
  • EPA programs are media-based: Clean Air Act (Title V permits, 40 CFR 68 Risk Management Program), Clean Water Act (NPDES permits, SPCC under 40 CFR 112), RCRA (40 CFR 260–273), CERCLA release notification and reportable quantities, EPCRA community right-to-know, TSCA.
  • DOT 49 CFR 171–180 governs hazmat classification, packaging, marking, labeling, shipping papers, and training, which must be recurrent every three years.

Thresholds you must know

  • RCRA generator status by monthly generation: very small quantity generator under 100 kg/month, small quantity generator 100–1,000 kg/month, large quantity generator over 1,000 kg/month. Accumulation limits: 90 days for large quantity generators, 180 days for small quantity generators (270 days if the waste travels over 200 miles).
  • SPCC plan required when aggregate aboveground oil storage exceeds 1,320 gallons, or buried capacity exceeds 42,000 gallons; plans are reviewed every five years.
  • EPCRA: emergency planning notification within 60 days of exceeding a threshold planning quantity; SDS and Tier II inventory by March 1 each year; TRI Form R by July 1.
  • PSM under 1910.119 applies at 1,500 lb chlorine or 10,000 lb anhydrous ammonia; RMP thresholds differ, for example 2,500 lb chlorine.
  • Recurring written programs: LOTO (1910.147), permit-required confined space (1910.146), HazCom with GHS labels and SDS (1910.1200), HAZWOPER (1910.120) with an annual 8-hour refresher.

Worked example

A water plant keeps a maximum of 5,000 lb of chlorine on site. Compare inventory to each threshold: 5,000 lb exceeds the 1,500 lb PSM threshold, so a full process safety management program is required, and it exceeds the 2,500 lb RMP threshold, so a Risk Management Plan must be submitted to EPA. The governing number is the maximum intended inventory, not annual consumption - a plant buying 40,000 lb a year in small cylinders can still trip the threshold. If inventory later drops below 1,500 lb, document the basis for de-registration and update the RMP.

Traps that cost marks

  • Confusing PSM thresholds with RMP thresholds.
  • Using annual throughput instead of maximum inventory on site.
  • Forgetting that Tier II is an annual March 1 filing.
  • Calling a consensus standard voluntary when a permit or incorporation by reference makes it enforceable.
  • Missing immediate notification to the National Response Center for a CERCLA reportable quantity release.
