Adam Karpa: One of the dirtiest plants I’ve ever worked in, ash EVERYWHERE, it rains through the plant all day.

Terry Haldin: I worked there in E & I ,2007 to 2014. They were replacing the ash pipes with ceramic lined pipes to extend their life. That place used enormous amounts of compressed air. And the ash transport was by air.

Is the white "cloud" peaking over the top of the mountain from the Conemaugh Power Plant?

I presume the long building stores coal because that coal pile is small.

Even though there is an active railroad (former Pennsy) next to the plant, it appears their coal is delivered by trucks instead of rail.

I originally thought it used trucks because it got its coal from the Conemaugh Power Plant, which is just down the road. Instead, "Seward sources its primary fuel from the 60+ million tons of waste coal reserves spread throughout the region. This unique supply chain enables Seward Generation to operate as one of the lowest cost solid fuel power plants in the PJM (Pennsylvania/New Jersey/Maryland) Region. Seward Generation is also currently one of the most environmentally friendly power plants in the country. Unlike traditional solid fuel plants, Seward Generation utilizes circulating fluidized bed technology (CFB) which enables the plant to burn up to 100% waste coal and lower harmful emissions. Alkaline-rich ash, a beneficial byproduct from the process, is returned to the mine sites and utilized in environmental reclamation projects. Through this process, Seward Generation has removed more than 40,000,000 tons of refuse from the Pennsylvania landscape since operations commenced." [robindale]

I presume that waste coal piles are like petco piles in that wind blows black dust off of them. That would explain why they have the long building for storage.

Before Unit 4, the units were small and the building that housed them has been torn down.
