Ozone Depleting Substances
Ozone in the stratosphere protects the Earth from the sun's ultraviolet radiation (UV) by reflecting it. Chlorine from chlorofluorocarbons (CFCs) reacts with the ozone, breaking it down. This allows the UV rays to pass through to the earth's surface.
An increase in UV radiation causes an increase in skin cancer, cataracts, weather pattern changes, smog, damage to plastics and cloth, suppresses the human immune system, decreases green plant growth.
The United States banned CFCs in all non-essential aerosols in 1978. The Montreal Protocol was signed by 23 nations in 1987. It limits the production of CFCs.
July 1, 1992 venting refrigeration became illegal. The Environmental Protection Agency established standards and requirements for the use and disposal of Class I and Class II ozone depleting substances (ODS). These regulations also apply to substitute refrigerants.
Definitions
MVAC - Motor Vehicle Air Conditioner
Appliance - Any household or commercial devise that uses a Class I or Class II
refrigerant, including air conditioners, refrigerators, chillers, or freezers.
Class I ODS Turn-In Procedures
All Class I ozone depleting substances that are recovered or new and are no longer required as well as empty cylinders and containers must be turned back into the Defense Reserve. Call Environmental at 269-6669/3201 to schedule a turn-in of these materials.
Examples of Class I ODSs include:
- R-11
- R-12
- Halon 1211
- Halon 1301
- Carbon tetrachloride
- Methyl chloroform (1,1,1-trichloroethane)
- Methyl bromide
Class II Odss include HCFCs. Examples of Class II ODSs include:
- R-22
- R-134A
- R-404
Record Keeping Requirements
There are record keeping requirements in the Class II permits to demonstrate we are not exceeding our operating limits or exceeding the minor source emission thresh holds. All records will be kept on-site in a single, readily accessible location.
Logbooks
Logbooks must be a hard copy log, not computer files. Monthly reports of the information contained in the logbooks may be sent in electronically, faxed, or hand-delivered. Logbooks must be maintained on the following equipment, permitted or not:
- Paint booths/spray painting operations
- Generators
- Blast cabinets
- Gear Arresters
- Boilers
- Chillers
- Water heaters (not electric)
Every month units with permitted equipment that have operating limits turn in usage information from the equipment log book. This information is entered into a database and the usage for the past 12 months are calculated. Monthly records are kept on file to demonstrate compliance with limits.
Units that are required to turn in monthly usage logs are required to submit the information to the Environmental Department the Friday of the first full week of the month. Reports can be emailed, faxed, or hand delivered. These records are due the Friday of the first full week of each month.
Miscellaneous Material Usage
Each month units turn in the material usage for the previous month. This report includes all materials such as solvent, adhesives, paint, oils, etc. The only items that are not report are office supplies and commercially available janitorial supplies. These reports are due the Friday of the first full week of the month.
EPA Method 9 Opacity Testing
Each month opacity emissions from generators and boilers are taken to ensure we meet the 20% opacity limit. This is also referred to as "reading smoke".
Technician Certification Records
Technicians must have a copy of their certifications on them. Keep a copy in your records on all current technicians. Forward a copy of technician certifications to Environmental, Air Quality. Keep a copy of past employee certifications.
ODS Inventory (Keep on hand for at least 5 years)
- Pounds of ODS procured/purchased by type
- Pounds of ODS disposed of by type
- Pounds of ODS in storage by type
- Manufacturer
- Model
- Serial number
- Capacity in tons
- Full charge
- Refrigerant type
- Location
Records documenting the date and type of service and the amount of refrigerant added to an appliance containing 50 pounds or more of refrigerant. Keep on hand for at least 5 years.
Recovery or Recycling Equipment Inventory (Keep on hand for at least 5 years)
- Manufacturer specifications
- Manuals
- EPA Refrigerant Recovery or Recycling Devise Acquisition Certification Form
Call Environmental immediately at 269-6669/3201 and fax a copy of the report by the end of the following business day to 269-5216.
Reclamation Records (Keep on hand for at least 5 years)
Receipt stating amount turned in in pounds, name address and phone number of reclaimer.
Appliance Disposal Report
Keep on hand for at least 5 years.
Technician Certification
Anyone who installs or performs maintenance on an appliance or disposes of an appliance and may reasonably be expected to release a Class I or Class II ozone depleting substance must be certified through an EPA-approved certification organization. There are four levels of certification, depending on what type of appliance you will be working on:
- Type I for small appliances
- Type II for high-pressure, very high-pressure
- Type III for low-pressure appliances
- Universal for low-pressure and high-pressure appliances
- For MVAC and MVAC-like appliance the technician must be Type II certified or be certified in accordance with 40 CFR 82.40
