SUPPLEMENTARY INFORMATION: On October 20, 2010, the Pennsylvania Department of Environmental Protection (PADEP) submitted a revision to its SIP for the control of particular matter (PM) emissions from the operation of outdoor wood-fired boilers (OWBs).

I. Background On July 18, 1997 (62 FR 38652), EPA amended the National Ambient Air Quality Standard (NAAQS) for PM to add a new standard for fine particles, using fine particulates equal to or less than 2.5 micrometers in diameter (PM2.5) as the indicator. EPA set the health-based (primary) and welfare-based (secondary) PM2.5 annual standard at a level of 15 micrograms per cubic meter ([mu]g/m3) and the 24-hour standard at a level of 65 [mu]g/m3. The health-based primary standard is designed to protect human health from elevated levels of PM2.5, which have been linked to premature mortality and other health effects. The secondary standard is designed to protect against major environmental effects of PM2.5 such as visibility impairments, soiling, and materials damage. On October 17, 2006 (71 FR 61236), EPA revised the primary and secondary 24-hour NAAQS for PM2.5 to 35 [mu]g/m3 from 65 [mu]g/m3.

A significant and growing source of PM2.5 emissions in the Commonwealth of Pennsylvania is from OWBs. OWBs, also referred to as outdoor wood-fired furnaces, outdoor wood-burning appliances, or outdoor hydronic heaters, are free-standing fuel burning devices designed: (1) To burn clean wood or other approved solid fuels; (2) specifically for outdoor installation or installation in structures not normally intended for habitation by humans or domestic animals, such as garages; and (3) to heat building space or water by means of distribution, typically through pipes, of a fluid heated in the device, typically water or a water and antifreeze mixture. They resemble a small shed or mini-barn with a short smokestack on top. OWBs are being sold to heat homes and buildings; produce domestic hot water; heat swimming pools or hot tubs; and provide heat to agricultural operations such as greenhouses and dairies.

A concern associated with certain OWBs is the air pollution they may produce. Smoldering fires and short smokestacks may create heavy smoke to the ground that sometimes causes a neighborhood nuisance or an adverse impact on public health and the environment. Smoke from OWBs which forms from incomplete combustion, contains emissions from fine particle pollution, carbon monoxide, and other organic products, such as formaldehyde, benzene and aromatic hydrocarbons, all of which can cause cancer. When inhaled, fine particles from smoke emissions are carried deep into the lungs and can impair lung function and aggrevate existing medical conditions such as asthma, lung, or heart disease. Individuals particularly sensitive to PM2.5 exposure include older adults, people with lung and heart disease, and children.

Unlike indoor wood stoves that are regulated by EPA, OWBs are not required to meet a Federal emission standard, and the majority of them are not equipped with pollution controls. EPA initiated a voluntary program that encourages manufacturers of OWBs to improve air quality through developing and distributing cleaner-burning, more efficient OWBs. Through this voluntary effort, OWBs are certified and labeled to meet EPA emissions performance levels in two phases. Phase 1 of the program was in place from January 2007 through October 15, 2008. To qualify for Phase 1, manufacturers were required to develop an OWB model that was 70 percent cleaner-burning than unqualified models by meeting the EPA air emission standard of 0.6 pound PM per million British thermal unit (Btu) heat input as tested by an independent accredited laboratory. Phase 1 OWB models are labeled with an orange tag. Phase 1 Partnership Agreements ended when Phase 2 Partnership Agreements were initiated on October 16, 2008. To qualify for Phase 2, manufacturers must develop an OWB model that is 90 percent cleaner-burning than the Phase 1 OWBs and meet the EPA air emissions standard of 0.32 pound PM per million Btu heat output. The Phase 2 OWB models, just like the Phase 1 OWB models are also tested by an independent accredited laboratory. Phase 2 OWB models are labeled with a white tag. Additional information about the EPA voluntary OWB program is available on EPA’s Web site at http:// http://www.epa.gov/burnwise. Furthermore, the Northeast States for Coordinated Air Use Management (NESCAUM), which is a regional air pollution control organization, comprised of the air program directors of all the New England states, New York and New Jersey, in coordination with a number of states and EPA, developed a model rule for regulating OWBs (also known as outdoor hydronic heaters (OHHs)). The model rule was released in January 2007 and is available at http://www.nescaum.org/topics/outdoor-hydronic-heaters. The purpose of the model rule is to assist state and local agencies in adopting requirements that will reduce air pollution from OWBs. The model rule establishes emission limits and labeling requirements for new OWBs and contains the following components for both new and existing OWBs: setback requirements from property lines, structures, and homes; stack height requirements; and distributor and buyer notification requirements.

II. Summary of SIP Revision The SIP revision adds definitions and terms to Title 25 of the Pennsylvania Code (25 Pa. Code) Chapter 121.1, relating to definitions, used in the substantive provision of this SIP revision. In addition, the SIP revision adds a new regulation to 25 Pa. Code Chapter 123 (Standards for Contaminants) Particulate Matter Emissions, Section 123.14 (Outdoor Wood-Fired Boilers). The emission standard established in this SIP revision is the Phase 2 emission standard described in the EPA voluntary OWB program. The SIP revision is also based on the NESCAUM model rule.
