ODS Requirements for Refrigerant Recycling

EPA-Ozone Depleting Substance language

Certifications:

In accordance with 40 CFR 82.154, 82.156 and 82.166, technicians performing maintenance, service, repairs or disposal of HVAC and other refrigerant-containing equipment must be trained and certified through an EPA-approved program, as required and specified at 40 CFR 82. Copies of the certifications shall be maintained at the technician’s place of business and/or carried as a wallet card by the technician and a copy provided to the CES EV manager.

Equipment:

In accordance with 40 CFR 82.158 and 82.162, the Contractor shall provide and use certified refrigerant recycle/recovery equipment that meets the requirements of 40 CFR 82. The Contractor shall provide the Equipment

Owner Certification Statement to the Regional EPA office and keep a copy readily available on file. The

Certification Statement shall include manufacturer, model number and serial number for the equipment.

Inventory:

In accordance with the Environmental Protection Agency federal regulations, an up-to-date inventory of all regulated ODS-containing equipment at the WNY must be maintained. The Contractor shall maintain an accurate inventory of the HVAC and other refrigerant-containing equipment included in the contract, specifically those having 50 pounds or more of refrigerant when fully charged.

The inventory should include, at a minimum, the following information:

• Equipment identification (name, number, or other identifier)

• Name of the manufacturer

• Model number

• Type of equipment

• Type of refrigerant used

• Maximum refrigerant capacity of equipment

• If the equipment has multiple independent circuits and how many

• The capacity of each circuit in a multiple circuit unit

• Date of equipment installation; and

• Description of physical location of equipment within the facility

Changes and updates to this inventory are to be submitted to the Environmental Division monthly.

Small Equipment Leak Repair:

Whenever 5 pounds or more of refrigerant is added to an appliance normally containing < 50 pounds charge, the technician must investigate the unit for leaks. Contractor shall repair all refrigerant leaks within 48 hours of discovery. If the leak cannot be repaired within 48 hours, the Contractor must notify the Environmental Division within 24 hours of discovery. Contractor shall record leaks during PM’s and service calls and keep these records for inspection.

Contractor shall remove refrigerants prior to turn in of scrap or unserviceable HVAC and refrigeration equipment.

Contractor shall affix label to equipment and complete equipment disposal form.

The Contractor shall reclaim/recycle all refrigerants. Technicians are required to return recycled refrigerant to the purity levels specified by EPA prior to reuse in Air Force equipment. If the contractors recover any refrigerant and store it in cylinders for later use, records must be maintained stating:

• The type of refrigerant

• Amount of refrigerant added to the cylinder

• The identification number of the cylinder; and

• Where the cylinder is stored

If the refrigerant is not reused in equipment, all excess Class I ODS & HCFC-22 refrigerant shall be recycled by depositing in the Navy’s portion of the ODS Reserve in accordance with specified procedures

(www.dla.mil/Aviation/Offers/Services/AviationEngineering/OzoneDepRsrv.aspx). No Class I ODS or HCFC-22 refrigerant shall be transferred to the Contractor.

Technicians who handle refrigerants shall track all refrigerant usage that they transfer to or from any equipment or facility. Each time refrigerant is purchased, input or removed by the technician, the Contractor shall maintain a record of this activity. The Contractor shall maintain all maintenance and service records for the repair and disposal of all equipment, as well as for the use and recycle of all refrigerants. Each technician shall maintain a notebook with their completed logs either in their work truck or a secure workroom unless it is requested for audit purposes.

All technician-held records must be maintained for at least 5 years from the date of service.

Large Equipment Leak Repair:

For large HVAC and other refrigerant-containing equipment that normally hold 50 pounds or more of refrigerant, the Contractor shall investigate the unit for leaks for any amount of refrigerant addition or other measured indication of loss. If a leak is identified and repairs are not completed as part of the maintenance action, the Contractor must notify the Environmental Division within 24 hours of discovery. The leak must be brought down below EPA action levels (see below) within 30 days of discovery. If the repair cannot be made within this timeframe, an extension from the regulator must be applied for or the equipment must be taken offline (refrigerant evacuated and contained) until the repair can be made or the equipment is replaced.

EPA Action Levels for HVAC/Refrigeration Equipment Normally Containing 50 or More Pounds of Refrigerant:

• Commercial refrigeration - 35% (loss of total charge over 12-month period)

• Industrial process refrigeration - 35%

• Comfort cooling - 15%

• All other equipment - 10%

After leaks are repaired, the Contractor shall perform an initial leak verification test prior to replacing the full charge if the equipment was evacuated. If the equipment was not evacuated, the Contractor shall perform initial verification test as soon as practicable after repair. The Contractor shall also perform a follow-up leak repair verification test within 30 days of the equipment’s return to normal operation. The Contractor shall report all failed verification tests to the CO and Environmental Division within 24 hours.

Recordkeeping:

The contractor records (with records being provided to the CES Environmental Program Manager) when repairs are made to regulated appliances (equipment containing 50 lbs of refrigerant or more) that include the following:

• Date of the service

• Type of repair made to the unit

• The type and quantity of refrigerant added to each appliance

• The name of the technician servicing the unit

• The serial number and model (or other distinguishing information) of the unit serviced

• If more than one circuit in the unit, which circuit is serviced

• The leak rate for the repair

• The date, method used, and result of the initial verification test; and

• The date, method used, and result of the follow up verification test

If the contractor is unable to make a repair on a unit, they must contact the 11 CES POC outlined in the PWS. The data from field tickets, including the information provided above, should be entered into a central Excel spreadsheet that tracks the repairs of all ODS equipment. The contractor and CES Environmental Program Manager must keep all records for a minimum of 3 years.

Monthly Deliverables:

The central Excel spreadsheet that tracks all repairs performed on regulated ODS-containing equipment should be provided to the PWD Environmental Program Manager monthly. In accordance with the Environmental Protection

Agency federal regulations, the spreadsheet shall be provided to CE Air Program Manager monthly via email.

Submit records to 11 CES outlined in the PWS
