8020 Appendix T1
Ozone-Depleting Substances (ODS) for
This appendix provides Jefferson Lab with technical information regarding ozone-depleting substances (ODSs); and information with which to meet environmental needs and obligations regarding purchasing, using, storing, and disposing of ODSs.
Based on Executive Order 13423, the use of ODSs in new equipment and facilities is not authorized unless there is no safe, cost- effective replacement available. The use of ODSs in existing equipment is to be phased out as it reaches its expected service life. ODS replacements is allowed as long as the equipment can be maintained effectively in accordance with Environmental Protection Agency (EPA) regulations. Less harmful substances shall be used whenever practicable.
This technical appendix addresses all aspects of purchasing, storing, using, and disposing of ODSs at Jefferson Lab.
To the extent practicable, new contracts which require the use of ODSs conform to the requirements listed herein.
Regulation of ODSs used for experimental purposes are covered within ES&H Manual Chapter 3120 The CEBAF Experiment Review Process and ES&H Manual Chapter 3130 FEL Experiment Safety Review Process.

4.0 Process Steps
4.1 Substances identified by Title VI of the Clean Air Act Amendments (CAAA) of 1990:
· Class I Substances:
o Chlorofluorocarbons: used as refrigerants in air conditioning units and chillers [Includes R-11 and R-12, etc. in Group 1 and R-13, R-111, and R112, etc. in Group III.]
o Halons: used as fire suppressants in fire extinguishers
o Carbon Tetrachloride: used as a solvent
o Methyl Chloroform (1,1,1 Trichloroethane): used as a solvent
· Class II Substances:
o Hydrochlorofluorocarbons: used as refrigerants
· Other Regulations:
o Ozone-depleting substance phase out (CAAA 604 - 606) (T2-various)
o Prohibitions on venting ODSs (CAAA 608) (T2-4.2.1)
o Refrigerant recycling and recovery (CAAA 608) (T2-4.2.1)
o Servicing of motor vehicle air conditioning (Labeling Requirements CAAA 611) (T2-4.3.1)
o Safe alternatives policy (CAAA 612) (T2-4.3.)
4.2 Planning and Preparing for Phase Out of Class I Substances:
4.2.1 ODS replacements to keep existing equipment operating is allowed as long as the equipment can be maintained effectively in accordance with EPA regulations.
4.2.2 Lower hazardous substances are utilized whenever practical. (example: Hydrochlorofluorocarbon (Class II) compounds are used to replace Chlorofluorocarbon (Class I) compounds.)
4.2.3 New equipment containing/using ODSs are evaluated to determine if safe cost-effective alternatives are available, and if so the alternative is used.
4.2.4 Other plant-oriented needs are evaluated by the Facilities Management & Logistics (FM&L) Director:
ESH&Q Division monitors site-wide ODS inventory and consumption to ensure planned reductions are being met.
4.4 Class II Use
4.4.1 Jefferson Lab replaces equipment using Class I ODS prior to replacing Class II equipment. Class II ODSs are regulated but are less hazardous than Class I ODSs.
4.5 System and Equipment
4.5.1 Refrigerant Recycling and Recovery
Jefferson Lab abides by 40 CFR Part 82 and the following requirements addressed therein:
· Prohibits venting of Class I and II substances when used as a refrigerant. No person maintaining, servicing, repairing, or disposing of appliances shall knowingly vent or release a Class I or II substance.
· Contact the FM&L Service Desk at ext. 7400 for assistance with reclamation and containment of compounds prior to attempting to vent any device.
4.5.2 Equipment Maintenance
18.104.22.168 FM&L coordinates and oversee all maintenance, repair, service work of equipment utilizing Class I or II substances, and the disposal of any such equipment or appliances.
· Maintenance, service, or repair work plans include:
o Recovery and recycling of the Class I or II substances using equipment certified for that type of application.
o Evacuating the refrigerant in the unit according to specifications listed in the regulations.
o The use of a person being certified to use the recovery or recycling equipment.
· Class I or II substances are evacuated from equipment, according to requirements for servicing, prior to disposal.
· Owners of appliances containing 50 pounds or more of Class I or II substances keep service records documenting the date, type of service, type and quantity of refrigerant added. Such appliances would include chillers and large air conditioners.
· Existing closed ODS systems may continue to receive routine maintenance from available supplies for the system’s design life. Replacement substitutes shall be considered as early as possible where system performance and cost of substitutions are acceptable. Once design life is reached, safe cost-effective alternatives are evaluated.
· R-22 (Class II) is currently an acceptable substitute for use in central chiller plants. Some large central chillers have used R-11 and R-113 (both Class I) in the past and, at the present time, there is no known drop-in substitute. Substitution with R-22 requires the complete replacement of major system components.
4.6 Motor Vehicles
4.6.1 All motor vehicle air conditioning utilizing ODSs are serviced off site by trained and certified technicians.
4.7 Administration of ODSs
· Jefferson Lab requires warning labels on products purchased after 1991 containing or manufactured with Class I and Class II substances in accordance with Section 611 of the CAAA.
· Any Class II ODS bought by Jefferson Lab after January 1, 2015 will have labeling in accordance with Section 611 of the CAAA. Products not properly labeled will not be accepted by Jefferson Lab. Any of these products purchased by Jefferson Lab must have an advisory label that states the name of the substance and that it is harmful to the stratospheric ozone layer.
4.7.2 Alternative Materials
Jefferson Lab identifies alternatives for ODSs wherever possible.
4.8 Excess Materials Transfer/Disposal
4.8.1 Owners of equipment containing ODSs are responsible for using them properly and efficiently. When use is no longer necessary or feasible, excess material is turned over to the Jefferson Lab Property office (ext.5430) for proper disposal and/or transfer to the Department of Energy (DOE) central repository or to the Department of Defense as designated by the DOE.
Information on “environmentally friendly” alternatives for air pollutants other than ODSs is available through Environmental Department (ext. 7308).
