NYSDEC Part 494: What Owners and Operators Need to Know
New York State has significantly expanded its refrigerant reporting requirements under NYSDEC Part 494. Last year, owners and operators were required to register refrigeration and HVAC equipment with refrigerant charges exceeding 1,500 lbs. This year, that threshold drops sharply: any equipment containing more than 50 lbs. of refrigerant must now be registered with the state on an annual basis, and the penalties for non-compliance are steep.
These new requirements make it increasingly difficult to continue operating with synthetic refrigerants. Notably, even the newer A2L refrigerants fall under this mandate. The only path to exemption is switching to equipment that uses CO₂ or ammonia, as natural refrigerants are not subject to annual reporting.
This post summarizes who must comply, what must be reported, which refrigerants are affected, and the potential consequences of non-compliance.
Who Must Comply?
These requirements apply to owners and operators of refrigeration and HVAC equipment located in New York State that:
- Contain a refrigerant charge greater than 50 lbs., and
- Use a refrigerant with a 20-year Global Warming Potential (GWP) greater than 10
Important: New York State uses 20-year GWP values, not the more commonly referenced 100-year GWP values.
Which Refrigerants Are Subject to Reporting?
- Subject to reporting: All synthetic refrigerants, including HFCs and A2L refrigerants
- Exempt: Natural refrigerants such as CO₂, ammonia, and propane
What Must Be Reported Annually?
1. Equipment Information
Owners must provide baseline information for each regulated piece of equipment, including:
- System details: Equipment type, manufacturer, and model
- Charge capacity: Maximum refrigerant charge (lbs.)
- Substance used: The specific regulated refrigerant currently in the system (e.g., R-448A)
2. Service and Leak Repair Data
A primary objective of Part 494 is to track and reduce refrigerant emissions from leaks. Required reporting includes:
- Leak rate: Calculated using the rolling average method
- Inspection dates: When leak inspections were performed
- Detection events: When leaks were discovered
- Repair history: When service or leak repairs were completed
3. Refrigerant Purchase and Usage
Owners must track the flow of regulated refrigerants through their facility, including:
- Purchases: Total weight purchased, including supplier name and address
- Usage: Amount charged into equipment and amount recovered
- Inventory: Total weight of regulated substances stored on-site or off-site as of December 31
- End-of-life disposal: Total weight shipped for reclamation or destruction, including the receiver’s name and address
4. Administrative Updates
The following changes must be reported annually:
- Contact information: Updates to the designated facility contact
- Component replacement: Information on specified components replaced in registered equipment during the year
Penalties for Non-Compliance
Failure to comply with NYSDEC Part 494 can result in significant civil penalties. Because these regulations fall under Article 19 (Air Pollution Control) of the New York Environmental Conservation Law (ECL), they follow the penalty structure in ECL § 71-2103.
Per NYSDEC DAR-24 Policy (updated January 2024):
| Violation | Base Penalty | Continuing Penalty |
|---|---|---|
| First violation | $500 to $18,000 | Up to $15,000/day |
| Subsequent violations | Up to $26,000 | Up to $22,500/day |
| Knowingly venting refrigerants | Major violation | Up to $37,500/day (federal CAA) |
What Triggers Penalties?
- Missed registration deadlines: March 31, 2026, for large systems installed in 2025; March 31, 2027, for medium systems installed in 2026
- Record-keeping failures: Failing to maintain service logs, leak inspection records, or supplier invoices for five years
- Reporting failures: Not submitting the Annual Facility Stationary Refrigerant Report by March 31
- Leak management failures: Not calculating leak rates or completing required repairs within the mandated 14-day window
Additional Enforcement Actions
Beyond financial penalties, NYSDEC has the authority to:
- Issue injunctions: Legally compel a facility to cease using certain equipment or perform immediate repairs
- Issue administrative orders: Require facilities to enter into an Order on Consent, which typically includes a mandatory compliance schedule and public disclosure of the violation
The Bottom Line
This regulation should serve as a clear signal to operators using synthetic refrigerants, including A2Ls, that New York State is serious about its push toward natural refrigerants. Yes, natural refrigerant systems often carry higher upfront costs. But that calculation changes when you factor in the ongoing resources required to track compliance, manage reporting deadlines, pay for increasingly expensive synthetic refrigerants, and absorb higher energy costs, all before any penalties come into play.
