Refrigerant management is a key element of environmental compliance. The ozone depletion of legacy refrigerants and the high global warming potential of many modern HFCs have led the Environmental Protection Agency (EPA) and other organizations to implement strict compliance requirements.
Beyond compliance, refrigerant management is also essential to avoid the direct costs, emergency service calls, and unplanned downtime that come with leaks. Creating a strong refrigerant management program (RMP) that balances maintenance and compliance is critical. This blog post provides a comprehensive overview of what refrigerant management means for your team.
Refrigerant management is necessary across a wide range of facilities, industries, and applications. It covers both stationary refrigeration and comfort cooling (or air conditioning), including manufacturers, warehouses, and large commercial and retail buildings. Any facility with high-charge HVAC/R equipment must implement proper tracking and documentation to maintain compliance.
Organizations with the most significant refrigerant management needs include cold storage and temperature-controlled supply chains such as food and beverage processors, supermarkets, and big-box retailers. Industrial facilities of all kinds can need programs to manage refrigeration, chillers, and cooling loops.
Refrigerant compliance is vital for any facility that operates large air conditioning systems. Data centers, hospitals, universities, airports, offices, and other commercial properties often have rooftop AC units that easily pass the threshold for refrigerant compliance and reporting.
In the U.S., the EPA sets requirements for leak repair and reporting. For stationary refrigeration and cooling, requirements under Clean Air Act Section 608 apply to any equipment with a refrigerant charge of 50 pounds or more. Depending on refrigeration systems, equipment typically has a refrigerant charge of 2 to 4 pounds per ton of cooling capacity.
However, as of January 1, 2026, the AIM Act has lowered this threshold to a full charge of 15 pounds for refrigerants that have a global warming potential (GWP) over 53. That includes many of the most widely used refrigerants, including R-410A, R-134a, and R-404A/R-507A.
The scope of Section 608 covers a wide range of high-charge comfort-cooling and refrigeration assets. Large rooftop units, retail refrigeration, chillers, and industrial process refrigeration are all categories that face leak-rate thresholds and other compliance obligations.
Section 608 includes refrigerated trucks and other types of refrigerated transport. However, comfort-cooling in vehicles is covered by Section 609, which sets requirements for approved equipment, maintenance, safe disposal, and documentation.
Section 608 of the Clean Air Act sets requirements for how organizations handle refrigerants in stationary equipment. By mandating proper service practices, responsible recovery, and detailed recordkeeping, the regulation aims to reduce refrigerant releases into the environment.
Some key aspects of Section 608 include prohibiting venting refrigerants to the atmosphere, requiring recovery during service, and requiring disposal using approved recovery equipment. Section 608 ties compliance to qualified technicians, emphasizing best practices such as controlled charging, leak awareness, and proper handling of recovered refrigerant.
Under Section 608, there are specific trigger points that require formal action once a leak reaches a regulated threshold. This applies to stationary appliances with refrigerant charges above the threshold, requiring organizations to implement a refrigerant management program capable of detecting losses, quantifying rates, and responding quickly.
Triggers are based on the current leak rate expressed as the percentage of total charge that the equipment would lose over a year at that rate.

The owner or operator must repair leaks within 30 days of leak detection exceeding the trigger rate. An extended timeline of 120 days may apply in certain situations, such as where an industrial process shutdown would be required to repair. The 30-day requirement can also be waived if the owner or operator develops a one-year retrofit or retirement plan for the leaking equipment within 30 days of discovery.
Leak inspections are required after an appliance has exceeded the applicable trigger rate. Most equipment will require an annual inspection until the rate has stayed below the trigger rate for one year. For equipment with a full charge over 500 pounds, inspections are required every 3 months until the leak rate has remained below the trigger for 4 consecutive quarters. These inspections aren’t required for appliances that are continuously monitored by an automatic detection system that is audited and calibrated annually.
The EPA accepts two methods for calculating refrigerant leak rates. The annualizing method calculates the rate based on the amount of refrigerant added to restore full charge during a single service event. The rolling average method calculates the leak rate using all refrigerant additions over the past 365 days, or since the last successful follow-up verification test.
Recordkeeping and reporting are key elements of a compliant refrigerant management program. The EPA expects documentation related to the equipment’s full charge, refrigerant type, service dates, work performed, and quantity of refrigerant added or removed during each service event.
Organizations must also submit reports to the EPA in certain scenarios. If an appliance leaks 125% or more of its full charge in a calendar year, the owner or operator must submit a report describing the discovery of the leak and the repair efforts by March 1.
To ensure audit readiness, teams should also include inspections and both initial and follow-up verification tests associated with repairs in their reports. Supporting attachments, such as invoices and work orders, can further enhance report submissions.
Under Section 608, any person who could reasonably be expected to open or otherwise access a stationary refrigerant circuit during service, repair, or disposal must be certified. They must hold an EPA technician certification issued by an EPA-approved certifying organization after passing an exam. These credentials do not expire.
There are several Section 608 certifications, each aligned with different equipment types. Type I covers small appliances; Type II, medium, high, and very high pressure; and Type III, low-pressure chillers. Technicians can also receive a Universal certification covering all types. Technicians must also use EPA-certified recovery/recycling equipment during service and disposal.
Organizations must maintain technician profiles that include their certification type, certificate number, issuing organization, and proof on file. That includes both internal staff and third-party vendors. Linking technicians to specific facilities and work orders makes it easy to quickly see who performed each task and confirm that they were authorized to work on that system type.
Section 608 isn’t the only rule organizations must follow to maintain compliance. Other regulations may apply depending on the state of operation, the specific refrigerants used, the industry, and other factors. Your facility could face additional obligations or reporting requirements under these frameworks.
The EPA’s Greenhouse Gas Reporting Program (GHGRP) targets large direct emitters and certain suppliers. The program doesn’t apply to simply operating HVAC/R equipment. Industrial gas suppliers may be subject to fluorinated-gas reporting requirements under Subpart OO. Reporting is also necessary when importing or exporting pre-charged equipment under Subpart QQ.
State and local rules can also add registration, leak inspection, and reporting duties. California’s CARB Refrigerant Management Program is the most notable example, with Washington, New York, and New Jersey also having their own programs.
The 2020 AIM Act has set new requirements for a phasedown of hydrofluorocarbons (HFCs), targeting an 85% reduction in production and consumption by 2036. Various refrigerants face phaseouts and strict allowance allocations over the coming years, along with the 15-pound threshold for refrigerants with a high GWP. You can read ERA’s full blog post on the AIM HFC phasedown for all the details.
Creating an effective refrigerant management program is vital to maintain compliance and ensure efficient operations. Standardizing how you handle equipment, capture data, respond to leaks, maintain documentation, and prepare reports enables you to stay on top of refrigerant management across your entire organization.
The first step is to assign an overall program owner, such as an EHS manager or another leader. Depending on the size of your organization, you’ll also need to assign an individual at each site to own the day-to-day execution. Clearly define who is responsible for maintaining the refrigerant asset list, reviewing service documentation quality, and meeting leak response and required reporting deadlines.
You should create a document covering who is assigned to these roles across your facilities. This document should also include relevant maintenance personnel, outside contractors, and any other supplier or procurement details.
From there, you can create a standardized refrigerant management documentation workflow to ensure proper recordkeeping during service, repairs, leak response, or equipment changes. In general, such a workflow can follow these steps.
You should also have a clear workflow in place for employee and contractor onboarding. Make sure to collect the required certification proof from the start. Laying out expectations for ticket fields and attachments is also vital, and using standardized forms across your organization can ensure consistency when working with different contractors.
Setting up a refrigerant management program is just the first step. From there, you need to keep it going to maintain compliance. Setting up scheduled reviews will help prevent missed tickets or overlooked equipment, and an annual audit of your asset list will help ensure long-term accuracy.
Creating a simple compliance calendar around inspections, verification tests, and reporting deadlines is an effective strategy. Be sure to assign owners to all these recurring tasks, and use automated reminders to prevent them from slipping through the cracks. Keeping an eye on contractor work by periodically evaluating ticket quality is another important step.
