If you operate a restaurant in New York City that does any charbroiling, grilling, frying, or roasting, you are legally required to have a functioning pollution control unit on your kitchen exhaust. This isn't optional — it's NYC Local Law 38, and the DEP enforces it with fines up to $10,000 per violation.
What Is Local Law 38?
NYC Local Law 38 of 2015 (amending Administrative Code Section 24-149) requires all commercial cooking operations that produce grease-laden vapors to install and operate emission control equipment on their kitchen exhaust systems. The law has been enforced since July 1, 2016.
The NYC Department of Environmental Protection (DEP) oversees compliance. They inspect, issue violations, and levy fines.
Who Does It Apply To?
You need an ESP or equivalent pollution control if your restaurant:
- Does charbroiling or grilling of any kind
- Operates deep fryers
- Roasts meat in commercial ovens
- Uses wood-fired or coal-fired ovens or grills
- Produces grease-laden vapors from any cooking process
- Has kitchen exhaust exceeding 2,000 CFM
You may be exempt if:
- You only do light cooking (sandwich assembly, coffee, baking without frying)
- Your exhaust is under 2,000 CFM with no charbroiling
- You operate a food truck or temporary installation (different rules apply)
In practice, the vast majority of NYC restaurants that serve hot food need pollution control.
What Are the Requirements?
Standard Cooking Operations - Pollution control equipment must achieve at least **75% reduction in particulate matter** - An electrostatic precipitator (ESP) is the most common solution - Equipment must be registered with NYC DEP - Maintenance logs must be kept and available for inspection
High-Volume Charbroiling (>875 lbs of meat per week) - Equipment must achieve **95% particulate removal** - **Odor control** is also required (typically a catalytic oxidizer or activated carbon system in addition to the ESP) - More frequent inspections and stricter documentation
What Are the Fines?
| Violation | Fine Range |
|---|---|
| No pollution control equipment installed | $1,000 - $10,000 |
| Equipment installed but not functioning | $1,000 - $5,000 |
| No maintenance logs available | $1,000 - $2,500 |
| Repeat violation | Up to $10,000+ |
| Failure to register equipment with DEP | $1,000 - $2,500 |
Important: Each inspection can result in multiple violations. Not having logs AND having a non-functioning unit = two separate fines in one visit. And the DEP doesn't need to announce inspections — they can show up triggered by a neighbor complaint.
What Equipment Qualifies?
The most common pollution control solutions for NYC restaurants:
- Electrostatic Precipitator (ESP) — collector cells use electrostatic charge to capture grease particles. Most common and cost-effective for typical restaurants.
- Rooftop Ecology Unit — integrated ESP with weatherproof housing, installed on the roof. Very common in NYC.
- Smoke Hog — brand name ESP, so common it's used generically (like "Kleenex"). Now owned by Parker Hannifin / Filtration Group.
- UV Oxidation — ultraviolet systems that break down grease in the exhaust stream. Often used with ESPs.
- Catalytic Oxidizer — burns off grease and odor compounds. Required for high-volume charbroiling.
- Activated Carbon Filters — absorb odor compounds. Used as secondary treatment after ESP.
What Maintenance Is Required?
The law requires you to maintain the equipment — not just install it. A non-maintained ESP that isn't actually collecting grease is still a violation.
Recommended maintenance schedule:
- Monthly: Check indicator lights, inspect pre-filters
- Quarterly: Full ESP cell removal and cleaning, ionizer wire inspection
- Semi-annually: Power supply check, carbon filter replacement, performance verification
- Annually: Comprehensive service with full documentation
You must maintain service logs. When the DEP inspector asks to see your maintenance records, "we clean it sometimes" is not acceptable. Dated, detailed logs signed by the service provider are what they want to see.
What Does Compliance Cost?
ESP installation typically costs $8,000 - $25,000+ depending on the system. Regular maintenance is a fraction of that — and a fraction of a single DEP fine ($1,000 - $10,000+ per violation).
The math is clear: routine quarterly maintenance vs a single fine that could be $10,000. Maintenance is cheaper. Every time. Contact us for a maintenance quote.
