Environmental Regulations, Permits, and Compliance Reporting
What the exam tests
This domain asks whether you can connect a facility activity to the right statute, permit condition, and report, then defend the answer with a deadline, threshold, and record. Expect questions on the Clean Air Act, Clean Water Act, RCRA, CERCLA, EPCRA, and the permit programs that implement them.
Core rules
- A statute authorizes; a regulation specifies; a permit adds site-specific limits. The permit is enforceable even when it is stricter than the regulation.
- NPDES permits govern point-source discharges to waters of the U.S.; Title V permits govern major air sources; RCRA permits govern treatment, storage, and disposal; industrial stormwater permits require an SWPPP and monitoring.
- EPCRA has separate triggers: Tier II inventory reports for hazardous chemicals at or above 10,000 lb, or 500 lb for extremely hazardous substances, and TRI reporting for listed chemicals above activity thresholds.
- CERCLA reportable releases have reportable quantities; notify the National Response Center immediately and follow state and local reporting.
- Compliance reporting is complete only when the correct signatory certifies it, supporting records exist, and deviations are reported under the permit’s rules.
Worked example
A facility begins storing 12,000 lb of a listed hazardous chemical, none of it extremely hazardous. The chemical is not on the TRI list. Tier II is required because the 10,000-lb threshold is exceeded; TRI is not triggered by quantity alone because the chemical is not TRI-listed. If the same chemical were an extremely hazardous substance, the Tier II threshold would be 500 lb. The reasoning is threshold-by-threshold: do not assume one report satisfies another.
Traps
Assuming a permit “shields” all operations; missing that a permit limit can be more stringent than a national standard; treating a benchmark as a limit; late or unsigned reports; reporting only annual totals when immediate release notification is required; and forgetting that records supporting a certification must be retained.
