Outdoor Wood-fired Hydronic Heaters

Voluntary Program

National Air Quality Conference

February 11, 2007

Larry Brockman

U.S. EPA - Office of Air Quality

Planning and Standard


Epa s voluntary residential wood smoke reduction initiative

EPA’s Voluntary Residential Wood Smoke Reduction Initiative

Major components

  • Great American Woodstove Changeout Campaign (Main focus)

  • “Burn Clean” National Education and Outreach Campaign

  • Supporting & Developing Standards (voluntary and/or regulatory) for Fireplaces, Woodstoves and Outdoor Wood-fired Hydronic Heaters

Petition to administrator 8 11 05

Petition to Administrator (8/11/05)

  • 6 northeastern States plus Michigan & NESCAUM

  • Revise woodstove NSPS or new NSPS

  • Federal regulation needed: avoid patchwork

  • Other state, local agencies, and citizens expressed interest


Our 2 part stakeholder strategy

Our 2-Part Stakeholder Strategy

  • Part 1 – EPA OWHH Voluntary Program

  • Part 2 – Model Rule (MR) for States


Part 1 voluntary program

Part 1: Voluntary Program

  • Goal: Reduced emissions from new OWHH sooner than Model or Federal Rule

    • Phase 1: new, cleaner models by 4/2007

    • Phase 2: even more stringent, date TBD


Text label for new owhh

Text “label” for New OWHH

“Test results from XX independent accredited laboratory indicate that this model meets the U.S. Environmental Protection Agency 2007 (Phase 1) voluntary program emissions level for outdoor wood-fired hydronic heaters (OWHH) when tested in accordance with EPA Method 28 OWHH. To minimize smoke, always operate OWHH in accordance with the manufacturer’s instructions found in the owner’s manual. Additional information about EPA’s voluntary program is available at www.epa.gov/woodboilers.”


Voluntary program c omponents

Voluntary Program Components

  • MOU

  • Permanent text on qualifying models

  • Hang tag

  • Table top display

  • Owner’s Manual text

  • EPA website


Benefits of voluntary owhh program

Benefits of Voluntary OWHH Program

  • Manufacturers redesign and market cleaner OWHH much sooner than with Federal rules

    • starting 4/2007

    • ~70% less emissions

  • Meets immediate needs of States and manufacturers


Nescaum model rule components

NESCAUM Model Rule Components

  • New OWH – Phase1

    • Emission limit [Phase 1: 0.44 #/mmBTU heat input]

    • Set-back from property lines [>300 feet]

    • Stack height [>5 feet above structures within 150 feet]

    • Proper operation and maintenance, label, notice to buyers

  • Existing OWH options

    • Shutdown by x date

    • Replace or shutdown prior to sale or transfer of real property

    • Setback of 500 feet & Stack height >5 ft above structures within 150 feet by Y

  • Phase 2 Emission Limit of 0.32#/mmBTU heat output

    • Based on AQ modeling to meet the NAAQS

    • For units that meet the Phase 2 emission limit, the set-back and stack height requirements are dropped


Expected reductions

Expected Reductions

  • Voluntary Program Phase 1 Units by 4/2007

    0.60 #/mmBTU heat input

    ~70% reduction

  • Model Rule Phase 1 as soon as 4/2008

    0.44 #/mmBTU heat input

    ~80% reduction

  • Model Rule Phase 2 as soon as 4/2010

    ~0.32 #/mmBTU heat output

    >90% reduction


Roll out next steps

Roll-out & Next Steps

  • Roll-out 1/29/07:

    • EPA news brief

    • EPA website with information for public

    • MOU packets for partnering manufacturers:

  • Complete infrastructure for manufacturers to deliver cleaner OWHH to market by 4/07
