Title: Boiler Area Source Rule


1
Boiler Area Source Rule
  • Kenya Stump,
  • Environmental Assistance Branch Manager, DCA

2
Who We Are?
  • Environmental Compliance Assistance Program
    (ECAP)
  • Located in Division of Compliance Assistance
    (DCA)
  • Provides assistance on air, water, and waste
  • Detailed assistance available to small businesses
  • Kenya Stump, Chad Von Gruenigen, Emily Ohde

3
Terminology?
  • The Boiler MACT covers boilers and process
    heaters located at major sources of hazardous air
    pollutants (HAP). Subpart DDDDD
  • The Boiler Area Source Rule covers boilers at
    area sources of HAP. Subpart JJJJJJ
  • Rule does NOT apply to boilers that are gas-fired
    (approximately 1.3 million units, or 87 of all
    area source boilers) or process heaters.
  • Most units that are covered by this rule will be
    required to conduct a tune-up every other year
    and will not have to install pollution control
    equipment.
  • Boilers burn fuel to produce steam that is used
    for heat or electricity
  • Process heaters heat raw or intermediate
    materials during an industrial process
  • A major source is a facility that has the
    potential to emit 10 or more tons per year (tpy)
    of any single HAP or 25 tpy or more of any
    combination of HAP.
  • An area source is a facility that has the
    potential to emit less than10 tons per year (tpy)
    of any single HAP or less than 25 tpy of any
    combination of HAP.
  • HAP Hazardous Air Pollutant
  • KyDAQ Division for Air Quality
  • EPA Environmental Protection Agency

4
Why Do We Have These Rules?
  • These rules satisfy Clean Air Act requirements
    for air toxics
  • EPA is legally bound to issue these rules
  • Developed under Clean Air Act sections 112 and
    129
  • Require EPA to set technology-based standards for
    toxics
  • Reflect levels achieved by best-performing
    existing sources
  • Generally may set less stringent standards for
    boilers at area sources.

5
What if Sources Need Help?
  • DCA and DAQ are providing ongoing compliance
    assistance
  • U.S. Dept. of Energy (DOE) and the U.S. Dept. of
    Agriculture (USDA)
  • DEP and UK Compliance Assistance Partnership
  • KPPC

6
Questions to Answer First!
  1. Do I have boiler?
  2. Is my boiler subject to the rule?
  3. Am I a major source for HAPs?
  4. What size are my boilers?
  5. What type of boiler do I have?
  6. What fuel do I combust?
  7. What are my installation dates on my boilers?

7
Who is affected by the rules?
  • Owners or operators of an industrial, commercial,
    or institutional boiler or process heater
  • Boiler means an enclosed device using controlled
    flame combustion and having the primary purpose
    of recovering thermal energy in the form of steam
    or hot water.
  • Process heater means an enclosed device using
    controlled flame, and the unit's primary purpose
    is to transfer heat indirectly to a process
    material (liquid, gas, or solid) or to a heat
    transfer material for use in a process unit,
    instead of generating steam.

8
Items Not Covered
  • Gas-fired boilers (a boiler that primarily burns
    gas is still considered a gas-fired boiler even
    if it also burns oil or other liquid fuel during
    periods of gas curtailment, gas supply
    interruption, startups, or for periodic testing
    not to exceed 48 hours during any calendar year)
  • Boilers that burn solid waste (these boiler are
    subject to incinerator standards)
  • Hot water heaters
  • Waste heat boilers
  • (heat recovery steam generators)
  • Temporary boilers
  • Residential boilers
  • Electric boilers
  • Electric utility steam generating units (EGUs)

9
Existing Or New?
  • New source means that you commenced construction
    or reconstruction of the boiler or process heater
    after June 4, 2010 and you meet the applicability
    criteria at the time you commence construction.
  • Existing source means you commenced construction
    or reconstruction of the boiler or process heater
    on or before June 4, 2010.

10
Are you an area source?
  • You must be an area source for Hazardous Air
    Pollutants (HAPs).
  • Check your permit for your classification.

Boiler MACT Tune-up Requirement
  • Subpart JJJJJJ NESHAP for area sources
  • Subpart DDDD- NESHAP for major sources

Chad Von Gruenigen Compliance Assistance
Specialist
16
  • The elephant in the room.

17
Boiler MACT
  • December 20, 2012 the EPA finalized the Boiler
    MACT.
  • This means the rules officially take affect.
  • The good news is there is time.

18
What is a NESHAP?
  • National Emission Standards for Hazardous Air
    Pollutants

19
What is a MACT?
  • Maximum Achievable Control Technology.
  • The Boiler MACT effects major and area sources
    for hazardous air pollutants (HAP)

20
Now what are major and area sources?
  • Major source- emits 10 tons per year of any
    single HAP or 25 tpy of any combined HAPs.
  • Area source- any stationary source of HAPs that
    is not a major source.

21
Whose not subject?
  • Any gas-fired boiler
  • Hot water heaters
  • Temporary boilers (used for less than 12 months)
  • Residential boilers
  • Electric boilers
  • Waste heat boiler (heat recovery steam
    generators)
  • Boilers used as control devices for other
    standards
  • Research and development boilers
  • Boilers subject to other NESHAP standards.

22
Is a tune-up required?
Heat Capacity ( Btu/Hr) Existing Biomass Units New (June 4th 2010) Biomass Units Existing Seasonal or limited use units New (June 4th 2010) Seasonal or limited use units
gt10 MM Yes Yes Yes Yes
lt10 MM Yes Yes Yes Yes
Provided the boiler uses an oxygen trim system
that maintains an optimum air-to-fuel ratio,
otherwise tune-ups required biennially.  
23
What is Seasonal or Limited Use?
  • Seasonal- boiler that undergoes a shutdown for at
    least 7 consecutive months each 12 month period.
  • Limited Use- boiler that burns any amount of
    solid or liquid fuels and has a federally
    enforceable average annual capacity of no more
    than 10 percent.

24
How frequently must I perform a tune-up
  • If the boiler is equipped with an oxygen trim
    system, is a seasonal or limited use every 5
    years.
  • Boilers without an oxygen trim system, arent
    seasonal or limited use every 2 years.

25
Initial Notification of Applicability
  • Submit no later than January 20, 2014
  • This one is easy and its hardcopy!

26
Where do I send the initial notification form?
  • This one is a hard copy.
  • Mail to
  • Kentucky Division for Air Quality
  • Program Planning Branch
  • Attn Jim Eubank
  • 200 Fair Oaks Lane, 1st Floor
  • Frankfort, Kentucky 40601
  • Jefferson County (only for Jefferson Co.
    facilities)
  • Louisville Metro Air Pollution Control
    District

27
Why perform a tune-up?
  • The overall savings outweigh the initial costs.
  • Less biomass burned less time, money and
    product wasted.
  • A tune-up extends the life of your boiler.
  • Not to mention its a requirement.

28
(No Transcript)
29
What if I already perform a tune-up
  • If you conduct the tune-up early the next tune-up
    is due no later than 25 months or 61 months as
    applicable. (This is the same time frame allowed
    for new boilers)
  • If the boiler is shutdown the tune-up must be
    conducted within 30 days of start up.

30
Who can perform a tune-up?
  • There is no certification requirement to conduct
    a boiler tune-up.
  • You will likely need someone that has boiler
    experience.

31
Before you begin
  • Preparation
  • Identify intent
  • Assemble boiler information
  • Identify environmental regulations
  • Identify measurement location
  • Establish tune-up timeframe etc.
  • Make as-found observations

32
Document tune-up
  • As-found conditions
  • Post tune-up conditions
  • Modifications and repairs completed
  • Recommended investigations and modifications
  • Identified shortcomings of equipment

33
Step 1
  • Inspect the burner / boiler and clean or replace
    components necessary.

34
Step 2
  • Inspect the flame pattern and adjust the burner
    to optimize the flame pattern.
  • A hot water heater is basically a small boiler.
    (Not regulated)

35
Step 3
  • Inspect the air-to-fuel ratio to ensure it is
    calibrated and functioning properly, if such a
    system is installed on the boiler.

This can even be done on a hot water heater as
shown in the picture
36
Where do I get a meter?
  • For around 1,800 dollars you can get everything
    you need.

37
Step 4
  • Optimize total emissions of carbon monoxide.

This can even be done on a hot water heater as
shown in the picture
38
Step 5
  • Measure the effluent stream of carbon monoxide
    and oxygen before and after adjustments.

This can even be done on a hot water heater as
shown in the picture
39
Step 6
  • Maintain a report containing information
    highlighted in 40 CFR 63.11224

This can even be done on a hot water heater as
shown in the picture
40
Initial Tune-up Compliance
  • Complete no later than March 21, 2014
  • Deadline for submitting the notification of
    compliance status (NOCS) July 19, 2014
  • (This submittal will be electronic)

41
Yes I said the notification of compliance status
(NOCS) is electronic.
  • Compliance and Emissions Reporting Interface
    (CEDRI)
  • Central Data Exchange (CDX)
  • www.epa.gov/cdx

42
What questions can you expect?
  • Information about the tune-up conducted as
    described above. (comments / corrective actions)
  • Carbon Monoxide (CO) levels (ppmv)
  • Oxygen (O2) (by volume)
  • Fuel used or delivered 12 months preceding tune-up

43
Initial Tune-up Compliance
  • Maintain records of dates and procedures of each
    boiler tune-up and the fuel used by the boiler.
  • Required information highlighted in 40 CFR
    63.11224
  • Maintain records on-site for the first two yeas
    and keep record for at least five years.

44
Subsequent Tune-up Compliance
  • Conduct the same performance tune-up as the
    initial tune-up in 40 CFR 63.11223
  • Complete the compliance certification for each
    tune-up. Currently this does not have to be
    submitted but now that submittal is electronic
    this will likely be a required submittal.

5. Energy Conservation Measures 6. Energy Savings
Comprehensive tune-ups and correcting excessive air losses, high stack temperatures, and excessive smoking Can result in fuel savings up to 20.
Installing insulation on hot water and steam pipes over 120F Ensure excessive heat is not lost in transmission
Combustion efficiency analyses A 3 decrease in flue gas O2 typically produces boiler fuel savings of 2.
Reset hot water supply temperature For every 11 deg F that the entering feed-water temperature is increased, the boilers fuel use is reduced by 1.
65
5. Energy Conservation Measures 6. Energy Savings
An upgraded boiler maintenance program including optimizing air-to-fuel ratio, burner maintenance, and tube cleaning Can save about 2 of a facilitys total energy use with an average simply payback of 5 months
An upgraded boiler maintenance program including optimizing air-to-fuel ratio, burner maintenance, and tube cleaning Every 40 deg F reduction in net stack temperature (outlet temperature minus inlet combustion air temperature is estimated to save 1 to 2 of a boilers fuel use.
An upgraded boiler maintenance program including optimizing air-to-fuel ratio, burner maintenance, and tube cleaning Removing a 1/32 inch deposit on boiler heat transfer surfaces can decrease a boilers fuel use by 2 removal of a 1/8 inch deposit can decrease boiler fuel use by over 8.
66
5. Energy Conservation Measures 6. Energy Savings
Installation or conversion to combined heat and power systems (co-generation) Use heat generated instead of heat dissipation to cooling towers (wasting energy)
Installation or conversion to combined heat and power systems (co-generation) Use for comfort/space heating or process heat, replacing other energy inputs
