Audits, Permits, Stormwater, Tier II, and SPCC — the 2026 Mechanics

What does an environmental compliance audit cover?

A defensible audit cross-walks six federal statutes at once — Clean Air Act, Clean Water Act/NPDES, RCRA, EPCRA, TSCA, and SDWA where on-site water systems exist — asking four questions for every regulated activity: is this facility subject, do permit limits match what's happening on the floor, are the records complete, and were prior findings corrected. Deliverables are a severity-classified findings register, a corrective action plan with owners and due dates, and an EPA Audit Policy disclosure matrix — the policy still provides up to 100% gravity-based penalty mitigation when violations are disclosed within 21 days and corrected within 60. Facilities that audit on a 24–36 month cycle catch findings at four-figure exposure; facilities that audit after the inspection notice find five-to-six-figure exposure with reduced Audit Policy eligibility.

How long do EPA permits actually take?

Budget against the rate-limiting permit: a state minor-source air construction permit runs 4–6 months; PSD runs 12–24 months with dispersion modeling and BACT analysis. An individual NPDES permit runs 6–18 months; MSGP stormwater NOI coverage takes 30–60 days. RCRA Part B (TSDFs only) is the longest of any EPA permit at 2–4 years — but most industrial facilities only need VSQG/SQG/LQG generator status under 40 CFR 262.13, which is recordkeeping-only, not a permit.

Does your facility need an industrial stormwater permit?

If you're in one of 30 specified industrial sectors with materials or processes exposed to precipitation — yes, via the federal MSGP or your state's parallel permit (TCEQ TXR050000, KDHE Industrial Stormwater, ODEQ OKR05, MDNR General Permit). The operational core is the SWPPP — a living document with drainage mapping, pollutant source inventory, control measures, and quarterly visual inspection logs. Stormwater is the most-cited CWA finding because outfalls are inspectable from public rights-of-way; exposure runs up to $66,712 per day. The 2026 MSGP reissuance adds quarterly PFAS indicator monitoring across 23 sectors — new NOIs are required under the final permit.

Who files Tier II, and when?

Any facility that stored hazardous chemicals above threshold during the prior calendar year: 10,000 lb for ordinary hazardous chemicals with an SDS, or 500 lb / the TPQ (whichever is lower) for Extremely Hazardous Substances like chlorine and anhydrous ammonia. Deadline: March 1, no extensions, to three recipients — SERC, LEPC, and the local fire department. Kansas (kansas.tier2online.com), Missouri (MDNR e-filing), Oklahoma (ODEQ), and Texas (TCEQ STEERS) each run separate portals. Aggregation is by chemical across the whole facility — a one-week inventory peak obligates a full-year report.

Does your facility need an SPCC plan?

Yes, if aggregate aboveground oil storage exceeds 1,320 gallons in containers of 55 gallons or larger and a discharge could reasonably reach navigable waters (40 CFR Part 112). Capacity counts, not contents — eight 250-gallon totes puts a facility over threshold even half-full. Standard plans need Professional Engineer certification; Tier I/II qualified facilities can self-certify. Five-year re-certification is mandatory, material changes trigger immediate amendment, and post-spill inspections almost always cite plan currency and secondary containment sizing (typically 110% of the largest container).

How does multi-state compliance actually get managed?

Federal statutes are mostly delegated, so KDHE, MDNR, ODEQ, and TCEQ each impose their own portals, fees, forms, and data fields — identical facilities in Wichita and Tulsa file through entirely different systems. Environmental compliance is a portfolio problem: 12 sites with 12 independent approaches have 12 failure modes; one compliance calendar, one audit protocol, and one corrective-action register produces one failure mode and twelve early-warning signals. That is the structure iSi's COOP retainer maintains across every site.
