Reducing Road Dust
Essar Steel Algoma has launched an aggressive campaign to reduce particulate emissions. Of note, in 2000, the leading source of particulate from the steelworks was road dust. In an effort to curb this source, we introduced a road dust reduction program designed to reduce airborne particulates from roadways by implementing a rigorous paving schedule combined with the use of dust suppressants. By the end of 2013, over 211,000 m2 of roadway were paved within the steelworks. With the implementation of an ongoing road maintenance program, the use of approved dust suppressants on non-paved roadways and regular street cleaning with flusher and vacuum sweeper trucks there has been significant reductions of particulate release from roadways.
In addition, as part of a site wide aesthetic revival, targeted landscaping of open areas through the planting of trees, grass and flower gardens has helped to reduce the amount of air-born dust stirred up by prevailing winds and material movement. In 2011, a surface area of approximately 50,000 m2 was covered using St. Marys Paper Biosolids and hydroseed.
Investing in Additional Emission Controls
To address point source emissions, the next leading source of onsite particulate, Essar Steel Algoma has made several recent investments in baghouse technology on our No. 7 blast furnace and at our dekish facility. These, in addition to existing emission control systems at our steelmaking and cokemaking facilities are extremely effective in capturing particulate matter. The Company has further invested in emission control systems for the Ladle Metallurgy Furnace, a system upgrade for the steel shop hot metal transfer area, dekishing and a Lime Plant baghouse upgrade.
Targeting Fugitive Emissions
There are numerous other targeted initiatives currently underway to address particulate emissions including an aggressive coal dust management program which will reduce fugitive emissions by nearly 50%. This includes the application of specialized dust suppressants and the development and installation of a 80,000 m2 wind berm surrounding the coal piles to deflect wind from blowing over the piles and to reduce wind blown coal dust.
Measuring and Monitoring
Essar Steel Algoma has an extensive system of monitoring stations operated in accordance with Ministry of Environment guidelines. A third party operates the stations which are strategically located off-site, and reports all emissions readings to the Ministry on an ongoing basis.
