The Hatfield Ferry Power Station in Pennsylvania was given permission, through three permits, this week by the state’s department of environmental protection to expand the site.

The permits allow the expansion of the landfill to the station, and to collect and treat all leachate – contaminated water that collects from landfills and a water obstruction and encroachment permit to fill in a wetland and build a replacement.

The expansion will allow a scrubber system to operate which, while significantly reducing the amount of air pollution, will generate a three-fold increase of waste.

Scrubbers, also known as wet flue gas desulfurization systems, reduce the amount of particulate matter and sulfur dioxide emitted from power plants.

Hatfield will cut 255,000 tons of sulfur dioxide, or SO2, and 1,900 tons of particulate matter each year after the units are installed.

The site, which is run by Allegheny Energy Supply, uses just over 9000 tonnes of coal a day and employees about 168 people.
