Refrigerant Policy

Facilities Services Idaho State University

Date: February 1, 2013

Mission:

The Facilities Services of Idaho State University is setting a policy in writing to comply with the U.S. Environmental Protection Agency's "No Vent Law", which prohibits venting of refrigerants into the atmosphere for any reason. Our mission is to reduce refrigerant emissions into the atmosphere to the lowest achievable and practical levels. We also intend to reuse recovered, recycled and reclaimed refrigerant to its maximum potential. It is our intention in good faith to develop maintenance and operational service practices that prevent refrigerant releases, and to recover or safely dispose of any substance using EPA regulations for proper refrigeration technology.

Responsibilities of the Maintenance and Operations Department, Facilities Services, Idaho State University

EPA Technician Certification:

As per the Clean Air Act Amendments Section 608, the four types of certifications for stationary equipment are as follows:

Type of equipment serviced Level of required certification
Small equipment (<5lbs) Type I
High and very-high pressure equipment Type II
Low pressure equipment Type III
All types Type IV Universal*

* Type IV Universal does not include automobile air conditioning systems.

For more details on technician certification refer to the following EPA web pages:

Evacuation Requirements:

Service technicians must evacuate air-conditioning and refrigeration appliances as per EPA Section 608 Refrigerant Recycling Rule.

Required Levels of Evacuation for Appliances** (Except for Small Appliances, MVACs, and MVAC-like Appliances)

Type of appliance serviced Inches of mercury vacuum using equipment manufactured*
Before Nov. 15, 1993 On or after Nov. 15, 1993
HCFC-22 appliance, or isolated component of such appliance, normally containing less than 200 pounds of refrigerant. 0 0
HCFC-22 appliance, or isolated component of such appliance, normally containing 200 pounds or more of refrigerant. 4 10
Other high-pressure appliance, or isolated component of such appliance, normally containing less than 200 pounds of refrigerant (CFC-12, -500, -502, -114). 4 10
Other high-pressure appliance, or isolated component of such appliance, normally containing 200 pounds or more of refrigerant (CFC-12, -500, -502, -114). 4 15
Very High Pressure Appliance (CFC-13, -503). 0 0
Low-Pressure Appliance (CFC-11, HCFC-123). 25 25mm Hg absolute

* Relative to standard atmospheric pressure of 29.9 inches of Hg.

Refrigerant Leaks:

Pursuant to EPA Section 608, appliances with refrigerant charges of greater than 50 pounds are required to repair leaks in the equipment when those leaks together would result in the loss of more than a certain percentage of the appliance's charge over a year. For the commercial and industrial process refrigeration sectors, leaks must be repaired when the appliance leaks at a rate that would release 35 percent or more of the charge over a year. For all other sectors, including comfort cooling, leaks must be repaired when the appliance leaks at a rate that would release 15 percent or more of the charge over a year. Preventive maintenance shall be performed to test for leak integrity and a yearly refrigerant audit will be performed by M&O HVAC Team.

Leaks must be repaired within 30 days of discovery. If the Maintenance and Operations Department of the Facilities Services develops a one-year retrofit or retirement plan for the leaking unit, then the 30 days repair requirement is waived. Industrial process refrigeration appliances requiring an industrial process shutdown qualify for 120 days to repair a leak.

For more details on refrigerant leaks refer to the following EPA web pages:

Safe Disposal:

All appliances with refrigerants, recovery equipment, recycling equipment, and refrigerant cylinders must be disposed of as per the "Safe Disposal Requirements of EPA Section 608" (copy attached).

For more details on safe disposal refer to the following EPA web page:

Labeling:

As per Air Conditioning and Refrigeration Institute Guidelines, all refrigerant containers of class I or class II substances must be labeled:

CFC/HCFC Warning
