EPA Air, Water and Chemical Reporting (US federal)
A list of checks and obligations with their cadence, ready to add to your agenda.
For US industrial facilities subject to federal environmental permits: Clean Air Act Title V permit, SPCC oil spill plan, NPDES industrial stormwater permit (MSGP), EPCRA Tier II and TRI chemical inventories, and refrigerant management. It does not cover RCRA hazardous waste, which has its own kit, asbestos, individually permitted process wastewater, or occupational safety. Note: nearly all of these programmes are delegated to the states, which may set lower thresholds, their own forms and different deadlines; this kit is the federal baseline only.

Submit the Title V semiannual monitoring report
The holder of a Title V permit must submit reports of all required monitoring to the permitting authority at least every six months, identifying every deviation from permit requirements. The report is certified by a responsible official and monitoring records are kept for 5 years. Applies only to facilities holding a Title V permit (major sources, NSPS or NESHAP sources, acid rain programme): the exact dates of the two annual submissions are fixed in the permit.

File the TRI Form R by July 1
TRI-covered facilities must submit Form R (or Form A where allowed) to EPA by July 1 for each listed chemical used above threshold during the previous calendar year, through TRI-MEweb. Proof is the submitted form plus the threshold calculations and supporting documentation; the chemical list changes almost every year, particularly for PFAS. Applies to facilities in covered NAICS sectors, or federal agencies, with at least 10 full-time equivalent employees that manufacture or process more than 25,000 pounds, or otherwise use more than 10,000 pounds, of a listed chemical; thresholds are far lower for PBTs and PFAS.

Carry out the quarterly routine facility inspection (MSGP)
Operators covered by the industrial stormwater Multi-Sector General Permit must have qualified personnel carry out a routine facility inspection at least once each calendar quarter, checking exposed areas, control measures and signs of pollution; at least once a year the inspection must take place while a discharge is occurring. Proof is the report with date, findings and corrective actions; inactive and unstaffed sites may move to a single annual inspection. Applies to facilities in the listed industrial sectors covered by EPA's MSGP: in most states an equivalent state general permit applies instead, with its own frequencies.

Submit the annual chronic leaker report
If an appliance leaked 125 percent or more of its full charge in a calendar year, the owner or operator must send EPA a report by March 1 of the following year describing the efforts made to find and repair the leak. Proof is the submitted report; because the Part 84 subpart B leak repair provisions apply from January 1, 2026, the first report falls due on March 1, 2027 for 2026 data. Applies only to appliances with a full charge of 15 pounds or more that leaked 125 percent or more of that charge in a calendar year.

Recover the refrigerant before the appliance is scrapped
The trigger is disposal: scrapping, replacement, sending a chiller, heat pump or air conditioner to the yard. The refrigerant must be recovered with EPA-certified equipment by a technician certified under Section 608 before the appliance leaves the site, and deliberate venting to the atmosphere is prohibited: the principle holds for ozone-depleting substances and for HFC substitutes alike, whichever of the two regimes governs periodic inspections. The duty belongs to the owner or operator, who keeps the recovery record and the technician’s certification number; scrapping without recovery also exposes the hauler who accepts the unit.

Hold the annual SPCC discharge prevention briefing
The owner or operator must schedule and hold a discharge prevention briefing for oil-handling personnel at least once a year, covering known discharge events, equipment malfunctions and recent precautionary measures. Proof is the briefing record with the attendance list, kept for 3 years like the SPCC inspection and test records. Applies to all SPCC-regulated facilities, for personnel who handle oil.

Establish which regime each appliance falls under
For every refrigeration or air conditioning system you need two facts: which refrigerant it holds and how much. Those decide the regime — ozone-depleting substances under the historic Section 608 (40 CFR part 82 subpart F), HFC substitutes under the 2024 AIM Act rule (40 CFR part 84) — and therefore which repair, verification and recordkeeping duties actually apply. The 2020 rule narrowed the reach of Section 608 for substitutes, so a sheet written before then may list duties that no longer apply, or miss new ones that do. The annual review of the inventory is an organisational task, but it is what makes every other refrigerant rule here trustworthy.

Perform the quarterly visual assessment of stormwater discharge (MSGP)
Each quarter the operator must collect a stormwater sample at each discharge point during a qualifying storm event, at least 72 hours after the previous one, and assess it visually within the first 30 minutes of discharge for colour, turbidity, odour, foam, oil sheen and settled solids. Proof is the form recording date, time and findings; exceptions for adverse weather and for climates with irregular discharges must be documented. Applies to all MSGP-covered operators, except for documented exemptions for inaccessible discharges or frozen conditions.

Submit the Title V annual compliance certification
The Title V permit holder must certify at least annually compliance with each term and condition of the permit, stating the compliance status and the methods used to determine it. The certification, signed by the responsible official, goes both to the permitting authority and to the EPA Regional Office. Applies to facilities holding a Title V permit: the date is fixed in the permit, which may require more frequent certifications.

Review the SPCC Plan every five years
The owner or operator must complete a review and evaluation of the SPCC Plan at least once every five years, amend it within six months where warranted and implement the amendments within six months of preparation. Proof is the signed review statement attached to the Plan; technical amendments need Professional Engineer certification, and the Plan must also be amended off-cycle whenever the site configuration changes. Applies to non-transportation-related facilities with aggregate aboveground oil storage above 1,320 gallons, in containers of 55 gallons or more, or buried storage above 42,000 gallons, that could discharge into US waters because of their location.

Submit the MSGP annual report by January 30
By January 30 each year the MSGP-covered operator must submit the annual report to EPA through NeT-MSGP, summarising the previous calendar year's routine inspections, visual assessments, monitoring and corrective actions. Proof is the submission receipt for the report. Applies to operators covered by EPA's MSGP: state general permits have their own annual reports with different deadlines.

File the Title V permit renewal application
A Title V permit has a fixed term of up to five years and the operator must file the renewal application within the window set by the state programme, generally not less than six and not more than eighteen months before expiry, to keep the application shield. Proof is the complete application certified by the responsible official. Applies to facilities holding a Title V permit: set the reminder at least 18 months before the expiry date shown on the permit.

File the Tier II chemical inventory by March 1
By March 1 each year a facility holding hazardous chemicals above threshold must submit the Tier II form for the previous calendar year to the State Emergency Response Commission, the Local Emergency Planning Committee and the fire department with jurisdiction. Proof is the submitted form and the three submission receipts; there is no federal extension even when March 1 falls on a weekend. Applies to facilities required to keep an OSHA Safety Data Sheet that in the previous year held at least 10,000 pounds of a hazardous chemical, or an Extremely Hazardous Substance at its Threshold Planning Quantity or 500 pounds, whichever is lower; many states lower the thresholds and impose their own portals and fees.

Refrigerant leak inspections after a leak
When an appliance leaks above the rate that applies to it, the owner or operator must have the leak repaired within the statutory deadline and then have the required verification tests and follow-up inspections carried out until the leak rate is shown to be back below threshold; where permitted, an automatic leak detection system may be used instead, with periodic audit and calibration. Proof is the inspection log with the leak rate calculations and the verification test reports. NOTE on the threshold and the frequency: they depend on which regime applies, and this kit does not publish them as single figures. The historic Section 608 framework (40 CFR part 82 subpart F) covers ozone-depleting substances and was narrowed by a 2020 EPA rule for substitute refrigerants; for HFCs the 2024 AIM Act rule (40 CFR part 84) runs in parallel. Before setting a date, establish which of the two regimes the equipment falls under — the dedicated rule in this kit covers that.
