The requirements of this section are to identify over-arching restrictions when working with refrigerant, MVAC, MVAC-like, or halon containing appliances. Unless otherwise noted, the requirements are applicable to University staff, contractor, and vendors. The University must only employ the services of contractors or vendors that adhere to the regulatory requirements of 40 CFR 82 and this program.
It is unlawful for any person, in the course of maintaining, servicing, repairing, or disposing of an appliance or industrial process refrigeration, to knowingly release or dispose of any Class I (including halons) or Class II substances, or non-exempt substitutes including blends and mixtures into the environment. Further, it is unlawful for any person to knowingly release a Class I or Class II refrigerant or a non-exempt substitute refrigerant including blends and mixtures after its recovery from an appliance.
De minimis releases associated with good faith attempts to recycle or recover refrigerants are not subject to this prohibition. Except for exempt substitutes, refrigerant releases are de minimis only if the release occurred while following all work practices of the requirements in 40 CFR 82. Contact the Air Quality Compliance Manager (AQCM) in the Environmental Quality Management Department (EQM) for further investigation if a release is thought to be de minimis.
Any person who could be reasonably expected to violate the integrity of the refrigerant circuit and release refrigerant to the environment during the maintenance, service, repair, or disposal of appliances must pass an EPA technician certification exam offered by an EPA approved technician certification program. Persons that dispose of small appliances, motor vehicle air conditioners (MVAC), or MVAC-like appliances are not required to be certified. Similarly, apprentices are not required to be certified if closely and continually supervised by a certified technician.
Activities reasonably expected to violate the integrity of the appliance refrigerant circuit include but are not limited to attaching or detaching hoses and gauges to and from the appliance; adding or removing refrigerant; adding or removing components; and cutting the refrigerant line. Activities such as painting the appliance, rewiring an external electrical circuit, replacing insulation on a length of pipe, or tightening nuts and bolts are not reasonably expected to violate the integrity of the refrigerant circuit. Activities conducted on appliances that have been properly evacuated are not reasonably expected to release refrigerants unless the activity includes adding refrigerant to the appliance.
The University must only use in-house technicians, contractors, or vendors that have current EPA certification. A copy of all University employee technician certifications must be retained on file with the technician’s specific Department. A copy must also be submitted to the AQCM. Employees of contractors and vendors must verify appropriate technician certification to the University as part of the contract procurement process when the work is reasonably expected to violate the integrity of the appliance refrigerant circuit or when the work includes recycling or disposal of the appliance or refrigerant.
The table below lists the required certifications needed to work on refrigerant appliances. Certified technicians may only work on appliances for which they have been properly certified.
The University may only sell unused cylinders of refrigerants, or unused cylinders of refrigerants used in MVAC or MVAC-like appliances to buyers that provide proof that the buyer, or at least one employee of the buyer, is a certified technician through the appropriate Subpart F (Recycling and Emissions Reduction) or Subpart B (Motor Vehicle).
The University may only sell used cylinders of refrigerant if the refrigerant was reclaimed by a certified reclaimer (refer to Section 4.4); is being transferred between one University facility to another; or for MVAC, was used only in a MVAC or MVAC-like appliance and will be used in a MVAC or MVAC-like appliance and was recycled with the requirements of Subpart B.
The University may sell refrigerant that is sold as part of an appliance with a fully assembled refrigerant circuit or an appliance component.
Records of refrigerant sales must be kept for three years. The invoice must include the name of the purchaser, the date of sale, and the quantity of refrigerant sold. The University must keep the documentation provided by the buyer to demonstrate employment of a person certified under Subpart F or Subpart B for sales of refrigerants which are not contained in an operable refrigerant circuit.
In order to purchase refrigerants other than in an operable refrigerant circuit, the University must employ a certified technician. As is the case in Purchasing/Stores, the seller may specify the certified technician be employed by a particular Department rather than the University as a whole.
The University does not reclaim refrigerant for sell to outside buyers. If the procedure changes, a process to meet the following requirements of 40 CFR 82.164 must be developed.
No person may alter the design of certified refrigerant recovery and/or recycling equipment in a way that would affect the equipment's ability to meet the certification standards of §82.158 without resubmitting the altered design for certification testing.
The University must use recovery and/or recycling equipment that meets the following:
