EPA Section 608 Regulation Explained
The legal heart of the EPA Section 608 program is a federal regulation called 40 CFR Part 82, Subpart F. It is organized into numbered sections, and exam questions are really just those sections turned into scenarios. This page walks through Subpart F section by section, in plain language, so you can see how the rules fit together. It is a study aid in our own words — not the official legal text. For the exact wording, read Subpart F on ecfr.gov or see our EPA resources page.

§ 82.150 — Purpose and Scope
The opening section explains why the regulation exists and what it covers. Subpart F implements the part of the Clean Air Act that restricts the release of refrigerants during the service, maintenance, repair, and disposal of appliances. In short, this section sets the stage: it tells you the regulation applies broadly to people who work with regulated refrigerants, and that its goal is to keep those refrigerants out of the atmosphere.
§ 82.152 — Definitions
Definitions are easy to skip and a mistake to skip. This section gives precise legal meanings to terms the rest of the regulation depends on — appliance, small appliance, refrigerant, recover, recycle, reclaim, technician, self-contained recovery equipment, and many more. A large share of exam mistakes come from mixing up recovery, recycling, and reclaiming, or from not knowing the exact definition of a small appliance. When a question turns on what a word means, this section is the source of truth.
§ 82.154 — Prohibitions
This section lists what you may not do. The central rule is the venting prohibition: it is illegal to knowingly release regulated refrigerant while servicing, maintaining, repairing, or disposing of appliances. It also restricts who may buy refrigerant, prohibits using uncertified technicians, and bars other practices that would undermine the program. If you remember one section number, make it this one — the prohibitions are the backbone of Section 608.
§ 82.155 — Safe Disposal of Appliances
This section covers appliances headed for disposal — refrigerators, window units, and similar equipment going to a landfill or scrap yard. It places responsibility on the people in the disposal chain to make sure refrigerant is recovered before the equipment is scrapped, and it addresses the documentation that verifies recovery happened. This is the legal basis for the disposal-focused questions common in the Type I section.
§ 82.156 — Proper Evacuation of Refrigerant
One of the most technical sections. It sets the required practices for getting refrigerant out of an appliance before it is opened for service or disposal — how deep a vacuum must be pulled, and how much refrigerant must be recovered. The requirements depend on the type and size of the appliance and on when the recovery equipment was manufactured. This section is where the small-appliance recovery percentages and the high-pressure and low-pressure evacuation levels live.
§ 82.157 — Appliance Maintenance and Leak Repair
This section governs leaks. It defines the leak rate thresholds that different categories of equipment may not exceed, the deadlines for repairing leaks once a threshold is crossed, the verification testing that must follow a repair, and the option to retrofit or retire chronically leaking equipment instead. The 2026 updates that lowered the covered charge size and extended coverage to HFCs work through this section. For the full breakdown, see our leak repair requirements guide.
§ 82.158 — Standards for Recovery and Recycling Equipment
This section sets the performance standards that recovery and recycling equipment must meet, and requires that such equipment be certified. It is the reason you cannot legally recover refrigerant with just any improvised pump — the equipment itself has to be built and certified to do the job to a defined standard.
§ 82.160 — Approved Equipment Testing Organizations
Recovery and recycling equipment is not certified by the EPA directly. This section describes how an independent organization becomes approved to test and certify that equipment against the standards in § 82.158. For a technician, the takeaway is simply that certified equipment has been independently tested.
§ 82.161 — Technician Certification
This section establishes the technician certification program itself — the Type I, Type II, Type III, and Universal certifications, the requirement to pass an EPA-approved exam, and the rules that approved certifying organizations follow. It is the legal basis for the credential you are studying to earn. See the exam overview for how the certification types work in practice.
§ 82.164 — Reclaimer Certification
Reclaiming refrigerant — reprocessing it to a like-new purity standard so it can be sold to a new owner — is a regulated activity. This section sets out how a reclaimer becomes certified, including meeting the purity standard and following recordkeeping and reporting rules. It explains why only certified reclaimers, not field technicians, can produce refrigerant that is fit for resale.
§ 82.166 — Reporting and Recordkeeping
Compliance has to be provable, and this section says what must be written down and kept. It covers records related to leak repair, refrigerant added to and removed from appliances, verification tests, chronic-leaker reporting to the EPA, and similar documentation. The practical lesson: if you add refrigerant to a system, the paperwork is part of the job, not an afterthought.
§ 82.169 — Suspension and Revocation
Finally, the regulation has teeth. This section describes how certifications — for technicians, equipment owners, or reclaimers — can be suspended or revoked when the rules are violated. It is a reminder that Section 608 certification carries ongoing responsibility, not just a one-time test.
Two short sections are not detailed above: § 82.162 is reserved (no current content), and § 82.168 incorporates outside technical standards into the regulation by reference. Neither is a common exam focus.
How to Use This With the App
As you practice, notice which section a question really comes from. A venting question is § 82.154. A recovery-level question is § 82.156. A leak question is § 82.157. Training yourself to map a question back to its section makes the whole exam feel smaller and more organized. Then open the app and drill that section's topic until it is automatic.
