US Regulation of Wood-burning and Indoor Air Pollution

Posted by Rachel Stansel on Wed, Jan 15, 2014 @ 01:39 PM

Recently, the US EPA released their final proposal to update the new source performance standards (NSPS) for new woodstoves and heaters, and to add NSPS for the first time for pellet stoves, furnaces, hydronic heaters, and masonry heaters.   The measures, if approved, would take effect in 2015.  The report states, "Emissions from wood stoves occur near ground level in residential communities across the country, and setting these new requirements for cleaner stoves into the future will result in substantial reductions in exposure and improved public health."

Wood heaters release smoke which increases the levels of various pollutants into the air.  These include volatile organic compounds (VOCs), carbon monoxide and particles (soot), all of which cause serious health concerns.  Those at greatest threat are children, the elderly and those with breathing conditions such as allergies, asthma, emphysema or other lung diseases. 

The proposal states that the tighter regulation will mean heaters burn 80% cleaner than those on the market today. Consumers will see cost savings due to lower fuel consumption and in projected health cost savings.  The total benefits are estimated to be $1.8 to $2.4 billion annually.The proposal is open for comment for 90 days and a public hearing is scheduled for Feb. 26, 2014.  To read the proposal, visit the EPA's website.

While these regulations aim to improve air quality in the US, scientists in India are striving to improve the conditions in India.  In 2012, India was ranked as having the worst air quality of the countries studied and in 2013 they ranked second to last.  Outdoor air pollution led to approx. 165,000 deaths in 2008 (up from ~141,000 in 2004) while internal air pollution claimed ~500,000 in 2004 according to World Health Organization figures.

The largest single source of these pollutants is the traditional cooking stoves, known as chullas.  One can find a chulla, which burns wood, remains of crops or dung, in more than 100 million Indian households.  A high level of smoke is generated due to poor fuel consumption.  The stoves use a great deal of fuel and the required cook times are long.  Since the cooking is done in the home, the poor indoor air quality effects women and children, who spend more time in the home, the most.  Scientists compared daily use of the traditional chulla to smoking 40 cigarettes a day. 

In addition, the environmental impact is high due both to the high consumption of wood as a fuel and the output of toxic smoke. 

Development of a move efficient stove aims to help.  These stoves, sold under the name Annapurna.  In Hinduism, Annapurna is the goddess of food and cooking, and in Sanskrit, the name Anna means “food” and purna means “filled completely.”

The Annapurna stoves have better combustion, require less fuel and cook more quickly, all leading to reduced pollution.  These stoves can run on electricity or can be set up to use a solar charged battery.   The efficiency of the stove comes from the addition of a small fan that draws air into the combustion chamber.  The manufacturer had the stove tested by accredited laboratories and saw a 50% decrease in fuel needs, a 70% decrease in smoke and a 50% decrease in cooking time.  Small changes such as this will make a large impact in the effort to improve air quality throughout India.

EPA Extends Comment Period for new Greenhouse Gas Regulations

Posted by Rachel Stansel on Wed, Nov 21, 2012 @ 09:49 AM

Last week, the EPA announced an extension of the public comment period for "Greenhouse Gas Reporting Program: Proposed Amendments and Confidentiality Determinations for Subpart I."  The initial deadline for comment  was December 17, 2012 and has been extended to January 16, 2013.  In their announcement, the EPA stated that the reason for the extended comment period is the inclusion of two additional pieces of information.  First, the summarization of a conference call the EPA held with the Semiconductor Industry Association in late October.  The second is the EPA response to questions raised during that call about the calculation of Tier 2A emissions factors.

In brief, the amendment proposes changes to some of the calculation methods being utilized, provides some clarification of terms/definitions and adjusts the requirements for reporting.  The amendments affect all manufacturers of electronics including semiconductors, LEDs, MEMS, LCDs and photovoltaic cells.  The full proposal can be viewed here, and you can add your comments to the public record.

The EPA also has a fact sheet, which summarizes the proposal and can be viewed on the EPA site.

American Lung Association Releases "State of the Air" App

Posted by Rachel Stansel on Fri, Jun 29, 2012 @ 10:40 AM

Here in CT, we are entering the months where unhealthy air quality emerges with the heat levels this summer.  The American Lung Association has released an new advertising campaign featuring TV, online and billboard ads announcing the new State of the Air® smartphone application.  The app, available for iPhone and Android, allows users to view EPA collected data on the air quality at their current location or at any other location of choice.  Read this post to learn more about this data.  The app is being praises as a user-friendly resource for people for low air quality affects most profoundly, those living with lung disease (such as asthma, people with heart disease or diabetes and the elderly and children.

ALA of the Northeast President and CEO, Jeff Seyler, was quoted to say, “We are excited to be able to provide this innovative tool so those with lung disease, and without, can effectively monitor their local air quality and limit their exposure to dangerous levels of pollution.”

The State of the Air app provides both the current and next-day air quality forecasts.  Users can set alerts to notify them when the local air quality fails to a code orange, which is unhealthy for sensitive groups.  Along with the quality information, the app provides tips on what activities are to be avoided depending on the current conditions.

The television and online messages are aimed at young people.  They feature Alvin Grimes, an air collector, who collects air samples in glass jars.  The promos tie into the ALA tagline "What are your lungs collecting?"  "Alvin" has his own, twitter account and facebook page where he shares tips and information on air and air pollution.  The TV spots can be viewed on his youtube page (one example below).
