11.11 - Safe Disposal and Refrigerant Transfer Reference

Module: Standalone Reference Appendices and Instructor Resources
Purpose: One consolidated reference for refrigerant recovery before appliance disposal, final-disposer/final-processor responsibilities, signed verification statements and contracts, technician certification boundaries, refrigerant ownership transfer and reclamation, cylinder end-of-use handling, and disposal documentation
Regulatory verification date: August 14, 2026
Primary Section 608 authority: 40 CFR §§ 82.154, 82.155, 82.156, 82.157, and 82.161
Additional current HFC cylinder authority: 40 CFR § 84.116, with principal disposable-cylinder requirements taking effect January 1, 2028
Current eCFR status checked: Title 40 displayed as up to date through August 12, 2026
Scope note: This file consolidates the disposal and refrigerant-transfer concepts already taught in Modules 2, 5, 6, 7, 8, 9, and 10. Numerical service evacuation requirements remain fully tabulated in 11.6 - Master Recovery and Evacuation Tables.md.

How to Use This Reference

For an appliance that is leaving service permanently, answer these questions in order:

1. WHAT KIND OF APPLIANCE IS IT?
2. WILL IT BE DISMANTLED ON-SITE
   OR ENTER THE WASTE STREAM INTACT?
3. WHO WILL RECOVER THE REFRIGERANT?
4. WHAT RECOVERY / EVACUATION REQUIREMENT APPLIES?
5. DOES THE PERSON NEED SECTION 608 CERTIFICATION?
6. WHO IS THE FINAL PROCESSOR / FINAL DISPOSER?
7. IS A SIGNED STATEMENT OR CONTRACT REQUIRED?
8. WHAT HAPPENS TO THE RECOVERED REFRIGERANT?
9. DOES REFRIGERANT OWNERSHIP CHANGE?
10. IS RECLAMATION REQUIRED BEFORE REUSE / SALE?
11. WHAT RECORDS MUST BE KEPT?
12. IS A DISPOSABLE REFRIGERANT CYLINDER ALSO BEING DISCARDED?

The central disposal rule is:

RECOVER REFRIGERANT PROPERLY
BEFORE FINAL DISPOSAL

The central refrigerant-transfer rule is:

SAME OWNER
→ recovered refrigerant can generally be returned
   to that owner's applicable stationary appliances
   without reclamation

NEW OWNER / RESALE FOR USE AS REFRIGERANT
→ reclamation generally required
→ check explicit regulatory exceptions

1. Two Disposal Paths

EPA distinguishes two practical disposal situations.

1.1 Equipment Typically Dismantled On-Site

Examples include:

• Retail food refrigeration.
• Central residential air conditioning.
• Chillers.
• Industrial process refrigeration.
• Other field-installed stationary refrigeration/A/C equipment normally dismantled where installed.

For these appliances:

REFRIGERANT
→ RECOVERED IN ACCORDANCE WITH
   THE APPLICABLE SERVICE-PRACTICE REQUIREMENTS
→ BEFORE DISPOSAL / DISMANTLING

The applicable evacuation requirement depends on:

• Appliance pressure category.
• Full charge.
• Recovery-equipment date.
• Whether a qualifying exception applies.

See:

11.6 - Master Recovery and Evacuation Tables.md

for the complete numerical table.

1.2 Equipment Typically Entering the Waste Stream Intact

Examples include:

• Household refrigerators.
• Household freezers.
• Window air conditioners.
• Other qualifying small appliances.
• MVACs.
• MVAC-like appliances.

These appliances may pass through:

OWNER
→ HAULER / RETAILER / COLLECTOR
→ SCRAP RECYCLER / LANDFILL / FINAL PROCESSOR

with the refrigerant circuit initially intact.

For these categories, current § 82.155 creates a special safe-disposal verification system.

2. Final Processor and Final Disposer

Current 40 CFR § 82.155 uses the term:

FINAL PROCESSOR

and defines it functionally as the person taking the final step in the disposal process.

EPA public guidance also uses:

FINAL DISPOSER

or:

FINAL PERSON IN THE DISPOSAL CHAIN

Representative final processors/disposers include:

• Scrap-metal recyclers.
• Landfill operators.
• Other facilities/persons taking the final disposal step.

For this course:

FINAL PROCESSOR
≈ FINAL DISPOSER

when discussing the § 82.155 safe-disposal responsibility.

3. Final-Processor Responsibility

For a:

• Small appliance.
• MVAC.
• MVAC-like appliance.

the final processor must do one of two things.

Path A - Recover Remaining Refrigerant

FINAL PROCESSOR
→ RECOVERS ANY REMAINING REFRIGERANT
→ ACCORDING TO §82.155(a)

or:

Path B - Verify Prior Recovery

FINAL PROCESSOR
→ VERIFIES THAT REFRIGERANT
   THAT HAD NOT PREVIOUSLY LEAKED OUT
   WAS PROPERLY RECOVERED
→ USING A SIGNED STATEMENT OR CONTRACT

The final processor cannot simply assume the appliance is empty.

4. Person Recovering Refrigerant for Disposal

The recovery person and the final processor may be:

THE SAME PERSON

or:

DIFFERENT PERSONS

The required certification depends on the appliance category.

4.1 Certification Summary

Critical Distinction

NO CERTIFICATION REQUIRED FOR
SMALL APPLIANCE / MVAC / MVAC-LIKE DISPOSAL

does not mean:

NO RECOVERY REQUIREMENT

The refrigerant must still be recovered to the applicable level using compliant recovery equipment.

5. Recovery Equipment Still Must Comply

Current § 82.155(a) requires persons recovering refrigerant from small appliances, MVACs, or MVAC-like appliances for disposal to use recovery equipment meeting the applicable standards.

Therefore:

PERSON MAY HAVE A DISPOSAL CERTIFICATION EXCEPTION

while:

RECOVERY EQUIPMENT STILL HAS TO MEET
THE APPLICABLE PERFORMANCE / CERTIFICATION REQUIREMENTS

EPA public guidance emphasizes this distinction.

6. Recovery Before Disposal

6.1 Small Appliances

Before disposal of a small appliance, current § 82.156(b) provides the familiar Type I recovery pathways.

The complete small-appliance definition still applies.

6.2 MVAC-Like Appliances

For disposal, current § 82.156(c) requires the appliance to be evacuated in accordance with:

40 CFR PART 82, SUBPART B

or system pressure reduced to or below:

102 mm Hg VACUUM

6.3 MVACs

For disposal, current § 82.156(d) similarly provides:

SUBPART B EVACUATION

or:

≤102 mm Hg vacuum

Do not substitute the stationary-appliance Table 1 values for this disposal pathway.

6.4 Other Stationary Appliances

For medium-, high-, very-high-, and low-pressure stationary appliances:

§82.156(a)
→ TABLE 1
→ APPLICABLE EXCEPTIONS

control the normal recovery/evacuation requirement before disposal.

See Section 11.6 for the full table.

7. Equipment Dismantled On-Site

EPA specifically identifies equipment such as:

• Retail food refrigeration.
• Central residential air conditioning.
• Chillers.
• Industrial process refrigeration.

as equipment typically dismantled on-site before disposal.

The rule concept is:

DO NOT BEGIN DISMANTLING
IN A WAY THAT OPENS THE REFRIGERANT CIRCUIT
BEFORE REQUIRED RECOVERY / EVACUATION

The responsible technician should:

1. Identify the refrigerant.
2. Determine appliance type/pressure category.
3. Determine full charge where needed.
4. Connect compliant recovery equipment.
5. Recover refrigerant to the applicable level.
6. Document the disposal recovery where required.
7. Route recovered refrigerant appropriately.
8. Only then proceed with refrigerant-circuit dismantling.

8. Intact Waste-Stream Appliances

For a refrigerator, freezer, window A/C, MVAC, or similar appliance arriving at the final processor:

REFRIGERANT STILL PRESENT?

If Yes:

FINAL PROCESSOR
→ RECOVER IT

If No because it was properly recovered earlier:

FINAL PROCESSOR
→ VERIFY PRIOR RECOVERY
→ SIGNED STATEMENT OR QUALIFYING CONTRACT

If No because all refrigerant leaked out before delivery:

FINAL PROCESSOR
→ OBTAIN THE REQUIRED LEAKED-OUT SIGNED STATEMENT

9. Signed Verification Statement

When prior recovery is verified using a signed statement, current § 82.155 requires the statement to include:

NAME OF PERSON WHO RECOVERED REFRIGERANT

ADDRESS OF PERSON WHO RECOVERED REFRIGERANT

DATE REFRIGERANT WAS RECOVERED

EPA public guidance explains that the final person in the disposal chain maintains the signed statement from the person/supplier dropping off the appliance when the appliance arrives without a charge.

9.1 Required Information Checklist

• Signed statement.
• Name of refrigerant-recovery person.
• Address of refrigerant-recovery person.
• Date of refrigerant recovery.
• Appliance/shipment identification sufficient for the disposal process.
• Statement retained by final processor as required.

Federal Core Fields

The exact federal core fields explicitly stated in § 82.155(b)(2) are:

NAME
ADDRESS
DATE OF RECOVERY

10. A Sticker Alone Is Not Federal Verification

EPA specifically states that it does not mandate or accept an ordinary disposal sticker as the required verification by itself.

Therefore:

"FREON REMOVED" STICKER
ALONE
→ NOT SUFFICIENT

The final processor still needs:

SIGNED STATEMENT

or:

QUALIFYING CONTRACT

unless the final processor performs the recovery.

A label or sticker may be useful operationally, but it does not replace the required federal verification information.

11. Contract Option

Instead of obtaining an individual signed statement for every appliance/shipment, a final processor may use a qualifying signed contract with a supplier.

The contract must establish that the supplier will either:

RECOVER ANY REMAINING REFRIGERANT
BEFORE DELIVERY

or:

VERIFY THAT REFRIGERANT
WAS PROPERLY RECOVERED
BEFORE THE SUPPLIER RECEIVED IT

EPA explains that the contract option is intended primarily to streamline transactions with regular commercial suppliers.

It is not a good substitute for the individual statement pathway for infrequent individuals or one-time “peddler” deliveries.

12. False Statements

Current § 82.155 makes it a violation for a person to accept a signed statement or contract when that person:

KNEW
OR
HAD REASON TO KNOW

that the statement/contract was false.

Therefore:

PAPERWORK
≠
SAFE HARBOR WHEN OBVIOUSLY FALSE

If the appliance condition indicates that the refrigerant was not properly recovered, the final processor must not simply ignore that evidence.

13. Final Processor Must Notify Suppliers

The final processor must notify suppliers that refrigerant must be properly recovered before appliances are delivered.

The notification may use:

• Signs.
• Letters to suppliers.
• Other equivalent means.

This makes the safe-disposal requirement part of the disposal facility’s normal receiving process.

14. Appliance With All Refrigerant Leaked Out

A special statement applies if all refrigerant has already escaped and recovery is impossible.

The final processor must obtain a signed statement indicating that:

ALL REFRIGERANT
HAD LEAKED OUT
BEFORE DELIVERY

and:

RECOVERY IS NOT POSSIBLE

14.1 What “Leaked Out” Means

Current § 82.155 defines this context as loss caused by:

• System failure.
• Accident.
• Other unavoidable occurrence.

It does not include refrigerant loss caused by:

• Negligence.
• Deliberate acts.
• Cutting refrigerant lines to empty an appliance.

Exam Rule

DELIBERATELY CUTTING THE LINE
→ NOT A VALID "LEAKED OUT" EXCEPTION

15. Final-Processor Recordkeeping

For small appliances, MVACs, and MVAC-like appliances, the final processor must keep copies of the required signed statements or contracts:

ON SITE

in:

HARD COPY
OR
ELECTRONIC FORMAT

for:

3 YEARS

Memory Rule

FINAL PROCESSOR
→ STATEMENT / CONTRACT
→ ON SITE
→ 3 YEARS

16. Technician Disposal Records: More Than 5 and Less Than 50 Pounds

A separate current recordkeeping rule applies to technicians evacuating refrigerant for disposal of appliances within § 82.156(a) that have a full charge:

MORE THAN 5 lb
AND
LESS THAN 50 lb

Records must be kept for:

3 YEARS

16.1 Per-Appliance Records

For each appliance:

• Company name.
• Location of the appliance.
• Date of recovery.
• Type of refrigerant recovered.

16.2 Monthly Recovery Totals

For each calendar month:

• Total quantity recovered.
• Organized by refrigerant type.
• From all disposed appliances covered by the rule.

16.3 Transfer for Reclamation / Destruction

Records also include:

• Quantity transferred.
• Refrigerant type.
• Whether transferred for reclamation and/or destruction.
• Person to whom it was transferred.
• Date of transfer.

Exact Boundary

>5 lb
AND
<50 lb

not:

5 to 50 lb inclusive

Exactly 5 lb and exactly 50 lb are outside this particular § 82.156(a)(3) range.

17. Large ODS Appliance Disposal Records

For a current § 82.157-covered appliance with:

50 lb OR MORE

of a class I or class II refrigerant or a blend containing an ODS, owner/operator records include applicable disposal information.

For each covered disposal event, records include, as applicable:

• Appliance identity and location.
• Date of disposal.
• Part(s) disposed.
• Type of disposal work.
• Name of person performing the work.
• Amount and type of refrigerant removed.
• Full charge.

The general § 82.157 record-retention period is:

AT LEAST 3 YEARS

unless a longer period is specified.

Detailed § 82.157 recordkeeping is consolidated in:

11.7 - Leak Repair Recordkeeping and Regulatory Reference.md

18. What Happens to Recovered Refrigerant?

Recovered refrigerant does not automatically become waste.

After recovery, it may be:

• Returned to an eligible appliance of the same owner.
• Recycled for same-owner reuse where appropriate.
• Sent to a consolidator.
• Sent to an EPA-certified reclaimer.
• Sent for destruction when appropriate.

The correct path depends on:

• Refrigerant identity.
• Contamination.
• Ownership.
• Intended future use.
• Whether it will be sold/distributed.
• Applicable refrigerant-management requirements.

19. Recover, Recycle, and Reclaim at Disposal

Recover

REMOVE REFRIGERANT
+
STORE IN EXTERNAL CONTAINER

No purity improvement is necessarily performed.

Recycle

RECOVER
+
CLEAN FOR REUSE

using processes such as oil separation and filter-driers, without meeting the full reclamation purity/verification requirement.

Reclaim

REPROCESS TO REQUIRED PURITY
+
VERIFY PURITY

using the applicable federal reclamation standard and analytical protocol.

Disposal Chain

APPLIANCE
→ RECOVER
→ SAME OWNER REUSE / RECYCLE
   OR
→ CONSOLIDATOR / RECLAIMER
   OR
→ DESTRUCTION

20. Same-Owner Refrigerant Reuse

Current § 82.156(h) provides that refrigerant may be returned:

TO THE APPLIANCE
FROM WHICH IT WAS RECOVERED

or:

TO ANOTHER APPLIANCE
OWNED BY THE SAME PERSON

without being recycled or reclaimed, except for the separate MVAC/MVAC-like framework.

High-Priority Rule

SAME OWNER
→ RECLAMATION GENERALLY NOT REQUIRED
FOR THIS STATIONARY-APPLIANCE TRANSFER

The technician still must ensure:

• Correct refrigerant identity.
• Appropriate system compatibility.
• No intentional venting.
• Proper charging/service practices.

The rule does not make contaminated refrigerant technically suitable for reuse merely because the owner is the same.

21. Ownership Change and Reclamation

EPA’s current Section 608 guidance summarizes the general rule as:

RECOVERED / RECYCLED REFRIGERANT
CHANGES OWNERSHIP
→ RECLAIM BEFORE RESALE / USE BY NEW OWNER

Current § 82.154(d) states that used class I, class II, or non-exempt substitute refrigerant generally may not be sold/distributed for use as refrigerant unless it has been reclaimed by an EPA-certified reclaimer, subject to explicit exceptions.

Exam-Level Rule

USED REFRIGERANT
→ NEW OWNER
→ RECLAIM

unless the scenario clearly fits a regulatory exception.

22. Explicit Used-Refrigerant Transfer Exceptions

Current § 82.154(d) contains exceptions to the general used-refrigerant reclamation-before-sale rule.

22.1 MVAC / MVAC-Like Recycling Path

Used refrigerant may follow the exception when it:

• Was used only in an MVAC or MVAC-like appliance.
• Will be used only in an MVAC or MVAC-like appliance.
• Is recycled in accordance with Part 82, Subpart B.

22.2 Refrigerant Contained in a Complete Appliance

Used refrigerant may be transferred with:

AN APPLIANCE
SOLD WITH A FULLY ASSEMBLED REFRIGERANT CIRCUIT

The refrigerant is part of the appliance sale.

This is different from selling loose recovered refrigerant in a cylinder.

22.3 Parent Company / Subsidiary Transfers

The rule provides an exception for transfers:

BETWEEN OR AMONG
A PARENT COMPANY
AND ITS SUBSIDIARIES

or among subsidiaries having the same parent company.

22.4 Federal Agency Transfers

The rule provides an exception for transfers:

BETWEEN / AMONG
A FEDERAL AGENCY OR DEPARTMENT
AND FACILITIES OWNED BY
THE SAME FEDERAL AGENCY / DEPARTMENT

23. Sending Recovered Refrigerant to a Reclaimer

A technician does not personally have to reclaim refrigerant in the field.

EPA explains that contractors/technicians can return recovered refrigerant to:

• A refrigerant manufacturer.
• Supplier.
• Wholesale distributor.
• Refrigerant recovery/consolidation company.
• EPA-certified reclaimer.

A consolidator can package/prepare refrigerant before reclamation.

Practical Chain

TECHNICIAN
→ RECOVERY CYLINDER
→ DISTRIBUTOR / CONSOLIDATOR / RECLAIMER
→ EPA-CERTIFIED RECLAMATION
→ FUTURE RESALE / USE BY NEW OWNER

Reclamation is a specialized process, not ordinary job-site recycling.

24. Selling Recovered Refrigerant

A technician may not simply recover refrigerant from Customer A and sell that unreclaimed refrigerant for use by Customer B.

General current rule:

CUSTOMER A USED REFRIGERANT
→ NEW OWNER / CUSTOMER B
→ RECLAIM FIRST

EPA specifically advises that used refrigerant must be reclaimed by an EPA-certified reclaimer before it can be sold for use as refrigerant, unless a regulatory exception applies.

A reclaimer or some distributors may accept or purchase recovered refrigerant for reclamation.

That transaction is not the same as selling unreclaimed refrigerant directly for use in another owner’s appliance.

25. Same Customer Versus New Customer Example

Example A - Same Owner

A contractor recovers R-22 from one rooftop unit owned by Building Owner A and later returns that refrigerant to another compatible stationary appliance owned by Building Owner A.

General Section 608 result:

SAME OWNER
→ RECLAMATION NOT REQUIRED
under §82.156(h)

subject to refrigerant identity, compatibility, and the separate MVAC/MVAC-like limitation.

Example B - New Owner

A contractor recovers R-22 from Building Owner A and wants to charge it into Building Owner B’s stationary equipment.

General result:

OWNERSHIP CHANGES
→ RECLAMATION REQUIRED
BEFORE USE / RESALE

unless a specific § 82.154(d) exception applies.

26. Avoid Refrigerant Mixing

During disposal recovery:

DO NOT MIX KNOWN DIFFERENT REFRIGERANTS
IN A CLEAN RECOVERY CYLINDER

Mixing can:

• Prevent simple same-owner reuse.
• Increase reclamation difficulty/cost.
• Reduce refrigerant value.
• Create uncertain pressure/composition behavior.
• Require special handling.

If refrigerant identity is uncertain:

IDENTIFY
OR
SEGREGATE AS UNKNOWN / CONTAMINATED

according to the reclaimer/distributor procedure.

27. Recovery Cylinder Is Not a Disposable Cylinder

Recovery Cylinder

REFILLABLE
→ DESIGNED / AUTHORIZED FOR REPEATED RECOVERY SERVICE

Disposable Refrigerant Cylinder

SUPPLY CONTAINER
→ NOT REFILLABLE
→ NEVER USE AS A RECOVERY CYLINDER

Do not confuse:

DISPOSING OF AN APPLIANCE

with:

DISPOSING OF A REFRIGERANT CYLINDER

The federal rules and safety issues are different.

28. End-of-Use Recovery Cylinders

A refillable recovery cylinder that is damaged, out of qualification, or being retired should not simply be:

• Intentionally vented.
• Cut open while refrigerant remains.
• Placed into ordinary scrap with pressure/refrigerant still inside.

Before retirement:

1. Determine refrigerant contents.
2. Route refrigerant to appropriate reuse, reclamation, or destruction.
3. Follow current cylinder owner/supplier and DOT/PHMSA requirements.
4. Follow state/local waste or scrap-facility requirements.
5. Ensure the cylinder is rendered safe only by a lawful procedure appropriate to the cylinder/material.

This course does not establish one universal federal “scrap preparation” method for every refillable cylinder.

Cylinder specification and local handling requirements vary.

29. Disposable Refrigerant Cylinders in 2026

The specific disposable-cylinder heel-management requirements in 40 CFR § 84.116 have a principal compliance date of:

JANUARY 1, 2028

Therefore, do not teach the future 15 in. Hg disposable-cylinder heel requirement as a current 2026 Section 608 appliance-disposal rule.

Current safe practice remains:

• Never refill a disposable cylinder.
• Do not use it as a recovery cylinder.
• Do not intentionally release remaining refrigerant.
• Follow refrigerant supplier/reclaimer and current applicable transport/waste requirements.

30. January 1, 2028 AIM Act Disposable-Cylinder Rule

Starting January 1, 2028, current 40 CFR § 84.116 applies when a person uses a disposable cylinder and:

1. The cylinder contains a regulated substance under Part 84.
2. The cylinder was used in servicing, repair, or installation of refrigerant-containing equipment or fire-suppression equipment.
3. The person does not intend to use the cylinder in future servicing, repair, or installation.

The user must send the cylinder for further processing to remove the remaining refrigerant:

HEEL

31. 2028 Disposable-Cylinder Destination Options

Unless an exception applies, a qualifying disposable cylinder may be sent to:

• An EPA-certified refrigerant reclaimer.
• A fire-suppressant recycler when applicable.
• A final processor capable of removing the heel.
• A refrigerant supplier capable of removing the heel.

A final processor/supplier removing the heel must then route the removed regulated substance to the required reclaimer/fire-suppressant-recycler pathway.

32. 2028 Certified-Technician 15 in. Hg Alternative

Current § 84.116(e) provides an alternative disposal path starting January 1, 2028.

A qualifying disposable cylinder may be discarded to a final processor without the ordinary heel-processing pathway when:

1. The heel was removed by a certified technician.
2. The heel was evacuated to:

15 in. Hg VACUUM

3. The technician provides a signed certification statement.
4. The statement is delivered to the final processor with the cylinder.

32.1 Required 2028 Certification Statement

The statement must:

• Certify that the heel was evacuated to 15 in. Hg vacuum.
• State the certified technician’s name.
• State the certified technician’s address.
• State the date the cylinder(s) were evacuated.
• Be signed by the certified technician.

The final processor must keep the signed statement for:

3 YEARS

33. Do Not Mix the 2028 Cylinder Value With Appliance Evacuation Values

This is one of the most important current-versus-future distinctions in Module 11.

15 in. Hg vacuum
UNDER §84.116(e)
→ FUTURE DISPOSABLE-CYLINDER HEEL ALTERNATIVE
→ JAN. 1, 2028

It is not:

• Type I small-appliance recovery requirement.
• Universal Type II appliance endpoint.
• Type III low-pressure appliance endpoint.
• Current 2026 cylinder rule.
• General recovery-cylinder disposal requirement.

For appliance evacuation values, use:

11.6 - Master Recovery and Evacuation Tables.md

34. 2028 Small-Can Exception

Current § 84.116(g) excludes qualifying small cans from paragraphs (b) through (f) of the disposable-cylinder rule when the cans:

CONTAIN NO MORE THAN 2 lb

and meet the small-MVAC-can sales exemption referenced in:

40 CFR §82.154(c)(1)(ix)

Do not apply this exception to every small disposable cylinder.

The can must satisfy the referenced regulatory conditions.

39. Worked Disposal and Transfer Examples

Example 1 - Household Refrigerator at Scrap Recycler

A household refrigerator arrives at a scrap recycler with refrigerant still present.

Result:

FINAL PROCESSOR
→ MUST RECOVER REMAINING REFRIGERANT

or otherwise cannot complete final disposal under the prior-recovery verification path because refrigerant is still present.

Example 2 - Refrigerator Already Recovered

A homeowner delivers a refrigerator that was properly evacuated earlier.

The final processor did not perform recovery.

Required verification:

SIGNED STATEMENT
→ NAME
→ ADDRESS
→ DATE OF RECOVERY

or a valid contract pathway where appropriate.

Example 3 - Sticker Only

A refrigerator arrives with a sticker reading:

"REFRIGERANT REMOVED"

but no required signed statement or qualifying contract.

Result:

STICKER ALONE
→ NOT SUFFICIENT FEDERAL VERIFICATION

Example 4 - Deliberately Cut Line

A supplier cuts a refrigerator’s refrigerant line before delivering it and signs a statement that the refrigerant “leaked out.”

Result:

NOT A VALID LEAKED-OUT CONDITION

because the loss resulted from a deliberate act.

Example 5 - Failed Appliance Lost Charge in Accident

An appliance suffered accidental damage and all refrigerant escaped before delivery.

Result:

The final processor may use the special leaked-out statement pathway when the facts satisfy the current rule.

Example 6 - Central Split System Being Replaced

A residential split system is disconnected and dismantled at the building.

Result:

RECOVER / EVACUATE
TO APPLICABLE §82.156 LEVEL
BEFORE REFRIGERANT-CIRCUIT DISMANTLING

The Type II disposal technician must have the appropriate certification.

Example 7 - Same Owner Reuse

A technician recovers refrigerant from one stationary appliance and returns it to another compatible appliance owned by the same person.

General result:

RECLAMATION NOT REQUIRED
under §82.156(h)

The technician must still ensure refrigerant identity and technical suitability.

Example 8 - Different Customer

A technician recovers refrigerant from Customer A and wants to use it in Customer B’s appliance.

General result:

NEW OWNER
→ RECLAIM BEFORE RESALE / USE

unless a specific §82.154(d) exception applies.

Example 9 - Technician Sends Refrigerant to Reclaimer

A contractor has a recovery cylinder containing used R-22 that is not needed for same-owner reuse.

Appropriate path:

SEND / RETURN TO
CONSOLIDATOR OR EPA-CERTIFIED RECLAIMER

Reclamation occurs before later resale/use by a new owner.

Example 10 - Disposable Cylinder Used as Recovery Receiver

A technician proposes to recover refrigerant into an empty one-time supply cylinder.

Result:

DO NOT DO THIS

Disposable cylinders are not refillable recovery cylinders.

Example 11 - 20-lb Stationary Appliance Disposed

A technician evacuates refrigerant from a covered stationary appliance with a 20-lb full charge for disposal.

Because:

20 lb
→ >5 AND <50

the technician keeps the §82.156(a)(3) disposal records for:

3 YEARS

Example 12 - 2028 Regulated-HFC Disposable Cylinder

After January 1, 2028, a technician has finished using a qualifying disposable cylinder containing a regulated HFC and does not intend to use it again.

Result:

The §84.116 heel-processing requirements apply unless an exception applies.

One option is the certified-technician alternative:

EVACUATE HEEL TO 15 in. Hg VACUUM
+
SIGNED CERTIFICATION STATEMENT
+
DELIVER TO FINAL PROCESSOR

40. High-Priority EPA 608 Exam Associations

FINAL DISPOSER / FINAL PROCESSOR
→ RESPONSIBLE FOR FINAL SAFE-DISPOSAL VERIFICATION

SMALL APPLIANCE / MVAC / MVAC-LIKE
DISPOSAL
→ TECHNICIAN CERTIFICATION EXCEPTION

CERTIFICATION EXCEPTION
≠
RECOVERY EXCEPTION

SIGNED PRIOR-RECOVERY STATEMENT
→ NAME + ADDRESS + DATE

STICKER ALONE
→ NOT SUFFICIENT

GENUINELY LEAKED OUT
→ SIGNED LEAKED-OUT STATEMENT

DELIBERATE LINE CUTTING
→ NOT "LEAKED OUT"

FINAL-PROCESSOR STATEMENTS / CONTRACTS
→ 3 YEARS

DISPOSAL RECORDS
>5 AND <50 lb
→ 3 YEARS

SAME OWNER
→ RECOVERED STATIONARY REFRIGERANT
   CAN GENERALLY BE REUSED WITHOUT RECLAMATION

NEW OWNER / USED REFRIGERANT SALE
→ RECLAIM FIRST
unless explicit exception

DISPOSABLE CYLINDER
→ NEVER REFILL

JAN. 1, 2028
→ PART 84 DISPOSABLE-CYLINDER HEEL RULE

41. Common Mistakes and Confusing Points

Mistake 1 - Assuming the Owner Who Discards the Refrigerator Is Always the Final Processor

The final processor is the person taking the final disposal step, such as the scrap recycler or landfill operator in many cases.

Mistake 2 - Thinking a Disposal Sticker Is Required

EPA does not require a sticker as the federal verification mechanism.

A sticker alone does not replace the signed statement or contract.

Mistake 3 - Thinking the Signed Statement Needs Only a Signature

The federal core information includes:

NAME
ADDRESS
DATE OF RECOVERY

of the recovery person.

Mistake 4 - Treating Any Empty Appliance as a Valid “Leaked Out” Appliance

The special rule does not cover negligence or deliberate acts such as cutting refrigerant lines.

Mistake 5 - Thinking Disposal-Certification Exception Means Venting Is Allowed

It does not.

Recovery requirements still apply.

Mistake 6 - Applying Small-Appliance Disposal Rules to a Split System

A residential split system is typically dismantled on-site and follows the applicable §82.156 Type II service-practice pathway.

Mistake 7 - Using the 4 in. Hg Small-Appliance Value for Every Disposal

The 4 in. Hg alternative belongs to the small-appliance recovery rule.

Other appliances use their own applicable recovery/evacuation requirements.

Mistake 8 - Assuming Recovered Refrigerant Must Always Be Reclaimed

Same-owner stationary reuse is generally permitted without reclamation under §82.156(h).

Mistake 9 - Assuming Recycled Refrigerant May Be Sold to Anyone

Used refrigerant sold/distributed for use by a new owner generally must be reclaimed first unless a specific regulatory exception applies.

Mistake 10 - Treating “Same Customer” as a Casual Business Relationship

The controlling concept is:

SAME OWNER / SAME PERSON

not merely:

• Same contractor.
• Same service company.
• Same building manager.
• Same refrigerant type.

Mistake 11 - Forgetting the Parent/Subsidiary and Federal Exceptions

The detailed regulation contains specific used-refrigerant transfer exceptions.

Do not replace the legal rule with an oversimplified “every ownership change always requires reclamation” statement.

For EPA exam preparation, however, the safe default is:

NEW OWNER
→ RECLAIM

unless the stem clearly establishes an exception.

Mistake 12 - Using a Disposable Cylinder as a Recovery Cylinder

Never refill a disposable cylinder.

Mistake 13 - Applying the Future 15 in. Hg Cylinder Rule in 2026

The §84.116 15 in. Hg heel alternative has a principal compliance date of:

JANUARY 1, 2028

It is not the current 2026 appliance-disposal endpoint.

Mistake 14 - Calling the 2028 Cylinder Heel a Type II Evacuation Requirement

It is a disposable-cylinder end-of-use rule under Part 84, not a Type II appliance Table 1 value.

42. Final Safe-Disposal Checklist

Before an appliance enters final disposal:

• Appliance type identified.
• Refrigerant identified if possible.
• On-site dismantling versus intact waste-stream path identified.
• Required recovery/evacuation level identified.
• Required technician certification identified.
• Compliant recovery equipment used.
• Refrigerant recovered before circuit destruction/dismantling.
• Recovery cylinder appropriate and not overfilled.
• Recovered refrigerant kept segregated.
• Same-owner reuse versus ownership transfer identified.
• Reclamation arranged when required.
• Final processor identified.
• Signed statement or contract obtained where required.
• Sticker not relied on as sole verification.
• Leaked-out statement used only for genuine unavoidable loss.
• Final processor supplier-notification system in place.
• Final processor records retained 3 years.
• >5 and <50 lb technician disposal records completed where applicable.
• ≥50 lb ODS owner/operator disposal records handled where applicable.
• Disposable cylinders not refilled.
• Future §84.116 requirements distinguished from current 2026 requirements.
• Cylinder/waste/transport requirements checked separately.
