Attorney General George Jepsen and Energy and Environmental Protection Commissioner Dan Esty say Connecticut can expect air quality improvements as the result of a new agreement with the country’s largest electric power generator.

Jepsen says as American Electric Power Company retro-fits its coal-fired plants,  it has agreed to a revision of the 2007 consent agreement involving the amount of sulfur dioxide its plants send toward Connecticut and other states downwind.

American Electric Power operates 16 coal-fired power plants in the Midwest and South. Jepsen says instead of a maximim 260,000 tons of sulfur dioxide emissions in 2016,  the new agreement calls for a maximum of 145,000 tons.
