## Read the Boilers NESHAP carefully.

-                                                                                                                              The following information helps you determine how your boiler or process heater may be affected by the Boilers NESHAP. However, the Boilers NESHAP is complex and affects units differently based on rated heat input, fuel type, and utilization. Find the Boilers NESHAP and compliance information at www.epa.gov/ttn/atw/boiler/boilerpg.html.

**Affected:**
- Boilers or process heaters located at a major source of hazardous air pollutants (HAP).
**Major source:** Potential to emit 10 tons/year of one HAP or 25 tons/year of all HAP combined. Emissions from the entire facility, including non-boiler or process heater sources, count toward major source status.
**Hazardous air pollutants:** Boilers and process heaters emit HAP such as arsenic, cadmium, chromium, hydrogen chloride, hydrogen fluoride, lead, manganese, mercury, and nickel. Emissions from each boiler or process heater vary. HAP are listed at www.epa.gov/ttn/atw/188polls.html.

***Affected units with no requirements or only initial notification:***
**No requirements:** Existing small units (all fuel types) and new small units (gas fuel) have no emission limits and no requirements: No monitoring, no records, no notifications.
**Initial notification:** Existing large units (gas and liquid fuel), new small units (distillate oil only or combined with gas fuel) have no emission limits and submit only an initial notification. No other requirements.

**NEW UNITS: **Commenced construction** **or reconstruction on or after January 13, 2003
**EXISTING UNITS: **Commenced construction before January 13, 2003

***Which units are affected?***

***Emission limits apply to these boilers or process heaters:***
** **

**Regulated Pollutants**
- Particulate matter (PM) or total selected metals (TSM) as surrogate for metallic HAP. TSM: Arsenic, beryllium, cadmium, chromium, lead, manganese, nickel, selenium
- Hydrogen chloride (HCl) as surrogate for inorganic HAP
- Mercury (Hg)
- Carbon monoxide (CO) as surrogate for organic HAP

**Compliance Alternatives**** **
**	****Units can meet emission limits through a combination of the following:**
- Conduct performance testing for units that have new or existing control devices
- Use emissions averaging (certain units)
- For HCl (measured as HCl and chlorine) and manganese, demonstrate low public risk
- For HCl, TSM, Hg, limit HAP content of fuel, demonstrate compliance through fuel analysis

**SMALL UNITS: **Any firetube boiler (regardless of size) and any other boiler or process heater _<_10 MMBtu/hr
**LARGE UNITS:** Any watertube boiler or process heater >10 MMBtu/hr

| FUEL TYPE | EXISTING UNITS | NEW UNITS |
| --- | --- | --- |
| Solid | PM or TSM
HCl
Hg | PM or TSM
HCl
Hg
CO |
| Liquid | None | PM
HCl
CO |
| Gas | None | CO |

**Solid**:
**Liquid**:
**Gas**:

- Burns any amount of solid fuel
- Burns liquid fuel alone or with gas
- Burns only gaseous fuel

**Read the Boilers NESHAP carefully.**

**Not Affected:**
- Solid waste incineration units covered under section 129 of the Clean Air Act
- Units covered by another NESHAP under 40 CFR part 63 (including hazardous waste units, chemical recovery boilers at pulp mills, secondary lead refining kettles, ethylene cracking furnaces, blast furnace gas fuel-fired units)
- Hot water heaters, blast furnace stoves, temporary boilers
- Direct-fired (contact) combustion units (e.g., direct contact dryers) where the combustion gases come into contact with the process materials
- Research and development units
