I was recently interviewed for an article in ACHR’s The News magazine, “EPA’s Proposed Changes to Section 608 Cause Concern in the Industry,” where I provided my perspective on the current state of leak detection, repair and other provisions.

Refrigerant leak response and repair regulations have placed our industry in uncertain waters. As you may know, the Environmental Protection Agency (EPA) has proposed a new rule that rescinds some provisions of its Section 608 mandate, affecting equipment with 50 lbs. or more of hydrofluorocarbons (HFCs) or other substitute refrigerants. These best practices were developed in consultation with the HVACR industry to ensure safety, establish proper reclaim and recycling processes, and of course, reduce carbon emissions.

In November 2016, the EPA extended the scope of Section 608 — from refrigerants containing ozone-depleting substances (ODS) to nonexempt substitute refrigerants such as HFCs. Because the Court of Appeals ruled in 2017 that the EPA could not ban HFCs, the agency has decided that it also did not have the authority to regulate these refrigerants under Section 608.

Establishing best practices

Awareness of the importance of leak detection has grown exponentially in recent years. Today, most companies understand that implementing a leak response and repair program is simply a best practice. And for those companies that have already taken steps to comply with Section 608, the vacating of this rule will have little impact.

I stated in the article: “These procedures not only benefit the environment but also help ensure HVACR equipment operates at peak efficiency, including at the lowest overall cost. One of the benefits of the existing regulations has been to raise the awareness of best practices related to HVACR maintenance. Increased awareness generally leads to broader adoption by those in the industry, regardless of whether regulations are in place.”

Simply put, leak detection and repair programs make good sense, regardless of the regulations in place or the type of refrigerant being used. However, with the reversal of Section 608, equipment operators will no longer be under federal mandate to follow these widely adopted refrigerant management best practices:

  • Conducting leak rate calculations when refrigerant is added to an appliance
  • Repairing an appliance that leaks above a threshold leak rate
  • Conducting verification tests on repairs
  • Conducting periodic leak inspections on appliances that exceed the threshold leak rate
  • Reporting to the EPA about chronically leaking appliances
  • Retrofitting or retiring appliances that are not repaired
  • Maintaining related records
  • Overseeing technicians’ use of certified equipment and the reclamation process

These procedures are already considered to be the optimal standard practice, and end users who are focused on operational excellence are likely doing many (or most) of them today.

Maintaining other key program elements

The absence of a federal mandate for responsible HFC management creates a quandary for our industry. Currently, the EPA is seeking comments about the remaining provisions of Section 608, raising concerns about the potential for overturning other benefits of programs — specifically, guidelines for refrigerant reclaim procedures and technician certification and training programs.

Proper refrigerant reclamation reduces the likelihood of introducing impurities, which could lead to premature failures and increased maintenance costs for owners of HVACR equipment. What’s more, the certification program provides the vital information on how to deal with the ever-growing number of refrigerants. As I stated in the article: “One benefit of certification is that wholesalers are able to sell refrigerants to technicians who have a sufficient background and understanding of their liability under the Clean Air Act.”

Path forward

Already, several states are adopting standards for leak detection and control. Again, as I noted in the article, “We are already seeing some states such as California enact regulations that adopt many of the requirements in Section 608. Other states will likely step in, which may create more headaches for the industry. This could create problems for the industry and lead to a patchwork of inconsistent regulations that would be challenging for manufacturers and service providers to navigate.”

As always, Emerson will help you stay informed about further changes to Section 608. Regardless of the regulatory decisions, we’ll continue to provide guidance and expertise on how to design and implement refrigerant management programs.

An Ounce of Prevention Could Help Save Lives, Reputations and Revenues

This blog is a commentary on an April 2018 article published on Science Daily’s website at which evaluated a recent study on the costs of food borne illnesses in restaurants.

It seems like every month there’s a new story of a high-profile food recall or restaurant shutdown due to food borne illness outbreaks. As if food retailers need to be reminded of the damage these incidents can inflict on a brand, too often we hear of major chains and manufacturers having to close their doors — in part due to food poisoning judgments. Even if these companies do manage to stay in business, the potential for financial, reputation and human costs is significant.

And if those weren’t enough incentives, restaurants also have regulatory drivers for food safety. The Food Safety Modernization Act (FSMA), for example, seeks to push for improved traceability throughout the food supply chain.

Foodborne illness outbreaks can certainly be major setbacks for restaurants, but to date, the impacts of these incidents on bottom lines have been difficult to quantify. Many restaurant retailers are not fully aware of the potential financial costs of these incidents. Knowing this information can help them determine how much to invest in appropriate food-safety measures.

Study shows costs are proportionate to the size of the outbreak

A recent study by Johns Hopkins Bloomberg School of Public Health suggests that just one outbreak can cost millions in lost revenue, fines, lawsuits, legal fees, insurance premium increases and more.

Based on computer simulations used in the study, a foodborne illness outbreak can have a large impact, regardless of the size of the restaurant or the outbreak. A fast food restaurant could incur anywhere from $4,000 for a single outbreak in which five people get sick to $2.5 million for a single outbreak in which 250 people fall ill (taking into account lost revenue, lawsuits, legal fees and fines).

According to the Centers for Disease Control and Prevention (CDC), the annual occurrences of foodborne illness are more common than we may think:

  • Approximately 48 million people get sick
  • 28,000 are hospitalized
  • 3,000 die from food-related illnesses, which are often referred to as food poisoning

Pathogens that caused outbreaks in restaurants from 2010–2015 include listeria, norovirus, hepatitis A, E. coli and salmonella.

Preventative actions are the cure

The question then becomes: What’s causing these pathogens to arise? Often, the leading causes can simply be traced to not adhering to basic food safety best practices: cross-contamination; time and temperature excursions; cleaning; and sanitation.

Of course, Emerson can play an integral role in helping retailers minimize temperature deviations and maintain optimal conditions throughout the supply chain. We know that out-of-tolerance temperatures over prolonged periods of time can contribute to many of the threats posed to food quality. Our capabilities in temperature management, tracking and recording at all stages of food’s journey have become increasingly important for cold chain operators.

Our GO Real-Time temperature trackers for the cargo space provide live monitoring and reporting of perishable product cargo container temperature and location from anywhere in the world. The solution captures and stores data in a cloud-based monitoring portal, then sends alerts and status reports via email or text message to help stakeholders ensure product freshness and safety at every step.

Designed for restaurants and supermarkets, our Cooper-Atkins products and solutions offer temperature management and monitoring products for both spot inspections and fixed locations where food is handled, prepared and stored. These powerful products give people the ability to access food conditions and predict, preempt and control any issues related to quality or safety. These real-time temperature trackers can be accessed anytime, anywhere with a network connection, helping retailers ensure only the freshest and safest products reach customers.

Potential loss outweighs the cost

The Johns Hopkins study reinforces what we already knew: that there is a significant potential for health, human and revenue losses from outbreaks of foodborne illnesses. With today’s advances in digital, connected technologies, operators all across the cold chain have the tools at their disposal to prevent these incidents.

As one of the experts cited in the report, “Paying for and implementing proper infection control measures should be viewed as an investment to avoid these costs, which can top a million dollars.”

Refrigerant Leak Detection and Regulatory Update

Proper refrigerant leak detection is essential for retailers, potentially saving them thousands of dollars annually and helping to meet regulatory requirements. For the full article, click here.

Refrigerant leaks can cause both economic and environmental disruptions for retailers. Today, the average supermarket has two to four refrigeration racks charged with approximately 3,500 pounds of refrigerant. According to the Environmental Protection Agency’s (EPA) GreenChill research, about 25 percent (875 pounds) of that refrigerant is lost each year due to leaks. At $7 per pound, this loss equates to an annual expense of about $6,100 — more than $600,000 annually over a chain of 100 stores. And that’s just the financial aspect. In the same 100-store example, nearly 70,000 pounds of refrigerant are leaked into the atmosphere.

Introduced in the 1990s to address emissions of ozone-depleting substances such as chlorofluorocarbon (CFC) and hydrochlorofluorocarbon (HCFC) refrigerants used in stationary refrigeration and air conditioning units, Section 608 of the Clean Air Act was revised in 2016 to include hydrofluorocarbon (HFC) refrigerants. This revision also introduced more stringent requirements for repairing leaks in larger appliances as well as new record keeping, reporting and disposal mandates.

Per the 2016 revision to Section 608, the next iteration of these requirements will take effect on January 1, 2019, and include the following changes:

Lower leak thresholds. The new thresholds are 30 percent (from 35 percent) for industrial process refrigeration (IPR), 20 percent (from 35 percent) for commercial refrigeration equipment (CRE), and 10 percent (from 15 percent) for comfort-cooling equipment.

Required inspection and monitoring. Section 608 now requires quarterly/annual leak inspections or the use of automatic, continuous monitoring devices for refrigeration and air conditioning equipment that have exceeded the threshold leak rate.

 New reporting requirements. Owners and operators must maintain hard or electronic copies of reports documenting the full charges of appliances and the types of automatic leak detection systems used. For chronically leaking appliances, owners/operators must also submit reports if their systems contain 50 or more pounds of refrigerant and leak 125 percent or more of their full charge in one calendar year.

 Disposal requirements. Technicians must keep a record of refrigerant recovered during system disposal from systems with charge sizes ranging from 5 to 50 pounds.

With all of these revisions on the horizon, it’s important to note that the EPA takes enforcement very seriously. The consequence of noncompliance can be significant: the agency is authorized to assess fines of $37,500 per day for violations.

We recommend that companies implement effective refrigerant leak detection programs to minimize refrigerant leaks and plan a response strategy in the event of a leak. Direct leak detection technology includes fixed or portable monitors installed on-site, which detect the concentration of refrigerants in the air. These can be set close to the anticipated leak airstream, in enclosed spaces and in areas near the floor where leaked refrigerants collect.

 The renewed regulatory focus on reducing refrigerant leaks has caused retailers to put more emphasis on developing efficient and effective leak detection strategies. Leak detection programs not only allow retailers to stay on top of regulations; they can potentially save costs associated with lost refrigerant, the degradation of refrigerated system performance and food loss.

Understanding Your EMS and Identifying Trends on the Horizon

Squeezing the most efficiency out of your energy management system (EMS) can be a pivotal part of your operation. Many store and franchise operators are only using around 10–20 percent of the overall power of their EMS. Optimizing your systems and getting your “money’s worth” out of your EMS can reduce energy and maintenance costs and potentially lower energy consumption.

Understanding Your EMS and Identifying Trends on the Horizon

To fully understand what an EMS does and how it can benefit you, a helpful comparison can be made by looking at the progression of automotive technologies. For example, today we are accustomed to our cars nearly being able to drive themselves (some can). That evolution began as industry leaders started incorporating electronics into vehicles to benefit drivers — things like an analog braking system that was connected to engine control modules which were connected to traction control systems. Manufacturers are blending these systems together, improving communication and thereby optimizing vehicles.

An EMS, essentially, follows the same sort of ideology, tying together key systems and the architectural layers of your operation. These start with the control layer, where electronics take sensor inputs and determine what actions to take with that information (turning on/off compressors, fans, etc.). Next, the supervisory layer handles things like data logging, bringing the data from different systems together and storing it for you to evaluate and analyze over a given time frame (days, weeks, months, etc.) — and generating alarms for anomalies and other problems.

Finally, the remote layer, or remote system, is a software platform (or something similar) that communicates with your on-site equipment and gathers data that you can view via a remote user interface to see trends in your operations. Obviously, this is key to your ability to manage all this information from a location away from your actual operation.

As your EMS continually collects data, it is important for you to make the most of that data and understand how your EMS can help you identify trends and improve the way your facility operates. Optimizing your EMS grants you visibility into what’s happening at any particular site within your building/enterprise. Average operational expenses for a supermarket are incredibly high, so knowing how to interpret data provided by an EMS allows you to solve your problems quickly and efficiently.

Several trends regarding smart buildings and EMS technology have emerged in recent years, including: building energy management hitting the “cloud,” increased demand for smart building products, the convergence of building communications protocols, and the blurring of the interface between smart buildings and the smart grid. These trends tend to drive innovation in four key areas: user interface and usability, integration, cloud connectivity, and extensibility and apps.
