Existing Source Compliance
September 13, 2007
Existing Source Compliance
March 12, 2005: Submit initial notification.
September 13, 2006: For sources
demonstrating low risk for hydrogen
chloride or manganese, submit eligibility
demonstration.
For sources demonstrating compliance
through fuel analysis, submit site-specific
fuel analysis plan at least 60 days before
demonstrating compliance.
September 13, 2007: Must be in
compliance with all requirements of the
Boilers NESHAP.
Submit Quality Assurance plan and test
plan and notify EPA of performance test at
least 30 days before performance test.
March 11, 2008 (latest date): Conduct
initial performance test and opacity test no
later than March 11, 2008 (advance notice
required).
May 11, 2008 (latest date): Notify EPA of
your compliance status within 60 days of
completing the performance test or initial
compliance demonstration.
July 31, 2008: Submit first semiannual
compliance report.

The Boilers NESHAP was published in the Federal
Register on September 13, 2004. Copies of the

lllG DOIIGTS INtOM/\r CdTGTU I ly. 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 atwww.epa.gov/ttn/atw/boiler/boilerpg.html.
Which units are affected?
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.
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
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.
Emission limits apply to these boilers or process heaters:

Solid: Burns any amount of solid fuel

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 (HCI) as surrogate for
inorganic HAP
• Mercury (Hg)
• Carbon monoxide (CO) as surrogate for
organic HAP
NEW UNITS: Commenced construction or
reconstruction on or after January 13, 2003
EXISTING UNITS: Commenced construction
before January 13, 2003
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
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 HCI (measured as HCI and
chlorine) and manganese, demonstrate
low public risk
• For HCI, TSM, Hg, limit HAP content of fuel,
demonstrate compliance through fuel
analysis
