Potential mitigation measures Use of natural gas (currently used, not widely available or cost effective) Burning bans Voluntary programs (currently in progress, success TBD) Woodstove change out program (in progress for over 4 years, highly popular)
Solid Fuel Burning Appliance Change Out Program
Woodstove change out program is currently the “meat and potatoes” Operating since July 2010 Have removed, replaced or repaired nearly 1,600 solid fuel burning appliances Recycled nearly 500 tons of steel Invested over $6 million dollars Current incentive level of $4,000 plus $300 worth of locally manufactured pellets or energy logs
All Removed Stoves Are Destroyed And Recycled (mandatory part of program)

Some More Interesting Than Others!
Some Are Outright Dangerous
So How Effective Are We?
Fairbanks Has A History Of Poor Air Quality During Winter Months Carbon Monoxide (CO) exceed allowable limits in the early 70’s Early attainment plans contained mitigation measures focused on behavior modifications Mandatory I/M Program Not easily accepted by the community Technology proved to be the long term solution
Frequent Sight During Winter Months
Vehicular Emission System Evolution Varieties of emission systems introduced in the late 60’s and through the 70’s 1975 introduced catalytic converters 1980 first widespread use of computer controls for air/fuel ratio, better combustion Tightening of emission standards cold start emission standards 1996 Tier I emission standards, 2000 Tier II
Technology Works Takes years to develop properly Acceptance by end users is normally slow Understanding and training to service industry Better long term solution
