Facilities with refrigeration systems in California may need to comply with the California Air Resources Board (CARB) Refrigerant Management Program (RMP) regulation. Compliance requirements include conducting periodic leak inspections; monitoring and repairing leaks; keeping accurate records; and, if applicable, reporting annually.

Regulated Facilities & Systems

Commercial facilities with stationary, non-residential refrigeration systems that have a full charge greater than 50 pounds of high-GWP refrigerant (i.e., GWP equal to or greater than 150) must adhere to this regulation.

Impacted facilities typically include:

  • supermarkets & grocery stores
  • cold storage warehouses
  • distribution & manufacturing
  • ice rinks
  • oil / gas production

Regulatory compliance requirements are based on facility and system category. Leak detection & monitoring requirements are dependent upon the size category of the system, similarly to the facility category.

Full Charge of SystemLeak Inspection 
≥ 2,000 lbs.Varies (Automatic Leak Detection May Be Required)Or each time an additional refrigerant charge ≥ 5 lbs. or 1% of the refrigeration system’s charge (whichever is greater) is added
200 to 2,000 lbs.Every 3 MonthsOr each time an additional refrigerant charge ≥ 5 lbs. or 1% of the refrigeration system’s charge (whichever is greater) is added
50 to 200 lbs.Every 12 monthsOr each time an additional refrigerant charge ≥ 5 lbs. or 1% of the refrigeration system’s charge (whichever is greater) is added

Certain large refrigeration systems are subject to automatic leak detection (ALD) monitoring requirements. For an ALD to be CARB complaint, it must meet these requirements:

  • An automatic leak detection system which directly detects the presence in air of a high-GWP refrigerant, sensors or intakes must be placed so that they will continuously monitor the refrigerant
  • Must accurately detect a concentration level of 10 parts per million (ppm) of vapor of the specific refrigerant(s) used in the refrigeration system
  • Alert the operator when a refrigerant concentration of 100 ppm of vapor of the specific refrigerant(s) is reached

Bacharach offers numerous solutions that meet CARB’s ALD requirements, including Bacharach’s Multi-Zone, Single-Zone, and MGS-250. What’s more, the Bacharach PGM-IR can be used effectively to track and trace refrigerant leaks on-site.
