What is the purpose of the Subpart 6J Initial Notification Form?
This form is being sent to facilities identified by Mecklenburg County Air Quality (MCAQ) as possibly having
boilers subject to new National Emission Standards for Hazardous Air Pollutants (NESHAP) for Industrial,
Commercial, and Institutional Boilers Area Sources (40 CFR Part 63, Subpart JJJJJJ or 6J). These standards
were promulgated by the US Environmental Protection Agency (EPA) on February 21, 2011. A copy of the rule
can be found at http://www.epa.gov/airquality/combustion/actions.html. The form is designed to help you identify
whether your facility is subject to Subpart 6J. Completion and submittal of the form to MCAQ satisfies
requirements for preparing an initial notification under that regulation.
Am I subject to Subpart 6J?
You are subject to Subpart 6J if you own or operate an industrial, commercial, or institutional boiler that is located
at, or is part of, an area source of HAPs. You must submit an initial notification if you are subject to Subpart 6J.
Boiler means an enclosed device using controlled flame combustion in which water is heated to recover thermal
energy in the form of steam or hot water. Controlled flame combustion refers to a steady-state, or near steadystate, process wherein fuel and/or oxidizer feed rates are controlled (§63.11237).

Commercial boiler means a boiler used in commercial establishments such as hotels, restaurants, and
laundries to provide electricity, steam, and/or hot water.

Industrial boiler means a boiler used in manufacturing, processing, mining, and refining or any other industry
to provide steam, hot water, and/or electricity.

Institutional boiler means a boiler used in institutional establishments such as medical centers, research
centers, and institutions of higher education to provide electricity, steam, and/or hot water.
Major source means any stationary source or group of stationary sources located within a contiguous area and
under common control that emits or has the potential to emit considering controls, in the aggregate, 10 tons per
year or more of any federally regulated hazardous air pollutant or 25 tons per year or more of any combination of
hazardous air pollutants (HAPs). A list of the regulated hazardous air pollutants can be found at
http://www.epa.gov/ttnatw01/orig189.html.
Area source means any stationary source of hazardous air pollutants that is not a major source.
Stationary source means any building, structure, facility, or installation that emits or may emit any regulated air
pollutant or any pollutant listed under the federal Clean Air Act.

[Attach sheet or add rows to the table for additional boilers, as necessary.]
a If
the facility has an air quality permit, use IDs that are consistent with those reported in the permit. If the facility
does not have an air quality permit, create an ID for the boiler (e.g. #1, #2, etc.).
b mmBtu/hr
refers to million British thermal units per hour. Boilers often have a nameplate listing the rated heat
input capacity on the unit. This rated capacity may have also been reported to the entity insuring the boiler or a
state labor and safety inspector.
c Report
all fuels that can possibly be used by each boiler (e.g., natural gas, bituminous coal, #6 fuel oil, #2 fuel
oil, bark, lumber, etc.).
5. Facility-wide Gas-fired Boiler Exemption - For your facility, indicate if either of the following two
scenarios is true. No more than 1 scenario could apply to your facility. These scenarios may not apply
at all to your facility.
Place a check () in the box if Scenario 1 or Scenario 2 is applicable to your entire facility.
Scenario 1 - All boiler(s) at my facility burn gaseous fuels. That is they only burn natural gas,
process gas, landfill gas, coal derived gas, refinery gas, hydrogen, biogas, or liquefied petroleum
gas (LPG). No solid or liquid fuels are/would be burned.
OR
Scenario 2 - All boiler(s) at my facility primarily burn gaseous fuels such as natural gas, process
gas, landfill gas, coal derived gas, refinery gas, hydrogen, biogas, or liquefied petroleum gas
(LPG). Some or all have the capability to burn liquid fuels; however, liquid fuels are/would be
burned only during periods of gas curtailment, gas supply emergencies, or periodic testing on
liquid fuels not to exceed 48 hours/year. No solid fuels are burned.
If you checked that either Scenario 1 or Scenario 2 applies to your facility, then you own
or operate gaseous fired boiler(s) under Subpart 6J. Subpart 6J does not apply to you.
Subpart 6J Initial Notification Form
Page 6
Skip ahead to Section No. 11.
If you did not check Scenario 1 or Scenario 2 for your facility, then you own or operate
at least one liquid or solid fueled boiler. Proceed to Section No. 6.
6. Boiler Type Exemptions – The following boiler types are not subject to Subpart 6J. For your
facility, identify if any boilers fall into these categories.
a. Gas-fired boiler. If your boiler burns gaseous fuels (e.g., natural gas, process gas, landfill gas, coalderived gas, refinery gas, hydrogen, or biogas) not combined with any solid fuels, or if your unit
burns liquid fuel only during periods of gas curtailment, gas supply emergencies, or periodic testing
it is a gas-fired boiler. Periodic testing of liquid fuel shall not exceed a combined total of 48 hours
during any calendar year in order to maintain your status as a gas-fired boiler.
b. Hot water heater – Means a closed vessel with a capacity of no more than 120 U.S. gallons in
which water is heated by combustion of gaseous or liquid fuel and is withdrawn for use external to
the vessel at pressures not exceeding 160 pound-force per square inch gauge (psig), including the
apparatus by which the heat is generated and all controls and devices necessary to prevent water
temperatures from exceeding 210 degrees Fahrenheit (99 degrees Celsius). For example, many
hot water heaters at an affected source that are used to heat bathroom or dishwashing water have
capacities no more than 120 U.S. gallons and meet the pressure requirements of this exemption.
c. Waste heat boiler - Means a device that recovers normally unused energy and converts it to usable
heat. Waste heat boilers are also referred to as heat recovery steam generators.
d. Boilers subject to other NESHAP standards. If your boiler is specifically listed as, or included in the
definition of, an affected source in another National Emission Standard for Hazardous Air Pollutants
(NESHAP) standard(s) under Part 63. This is not common for area sources.
e. Boilers that are used as control devices for other NESHAP standards. If your boiler is used as a
control device for another process that is subject to Part 63 and at least 50 percent of the heat input
to the boiler is provided by the gas stream that is regulated under another subpart, the boiler is
exempt from this rule. This is not common for area sources.
f.
Research and Development boilers. If your boiler is used specifically for research and development
it is exempt; for example, many universities or boiler manufacturers may have test boilers to
develop new designs or combustion modifications. This exemption does not include boilers that
solely or primarily provide steam (or heat) to a process or for heating at a research and
development facility. This exemption does not prohibit the use of the steam (or heat) generated
from the boiler during research and development, however, the boiler must be concurrently and
primarily engaged in research and development for the exemption to apply.
g. Boilers subject to section 129 of the Clean Air Act as solid waste combustion units. If your boiler is
specifically listed as an affected source in another standard(s) under section 129 (e.g.,
Hospital/Infectious Medical Waste Incinerators, Commercial/Industrial Solid Waste Incinerators,
Sewage Sludge Incinerators) you are subject to a section 129 rule instead of this rule.
h. Hazardous Waste Boilers. If your boiler is required to have a permit under section 3005 of the Solid
Waste Disposal Act or if your boiler is covered by 40 CFR part 63 subpart EEE you are a hazardous
waste boiler.
i.
Are any boilers at your facility used as identified above in items a-h?
Yes
No
(If No, you have boilers subject to Subpart 6J. Skip to Section No. 7)

to Subpart 6J. Complete Sections 7, 8, 9 and 10 below and sign the Certification Statement.
7. Is your facility a major source of HAP? (check one)
Yes. My facility is a major source of HAP*.
No. My facility is an area source of HAP.
*Note: A major source is a facility that emits or has the potential to emit 10 tons or more per year of
any one HAP or 25 tons or more per year of multiple HAPs. All other sources are area sources. If your
facility is a major source, 40 CFR 63 Subpart DDDDD applies to your boiler(s) instead of Subpart 6J.
Indicate major source status above and return this form to MCAQ using the address listed in Section
no. 12.
8. Does your facility have new or existing sources under Subpart 6J?
New source means that you commenced construction or reconstruction of the affected boiler after June
4, 2010.
Existing source means you commenced construction or reconstruction of the affected boiler on or
before June 4, 2010.
