ESCATAWPA, Miss. (AP) - Mississippi Power Co. officials say they are on track to complete the installation of two new scrubbers on time at Plant Daniel in Jackson County.

The Mississippi Press reports (https://bit.ly/1gVfA4A) the overall $660 million project has a completion date of April 2016.

Mississippi Power officials have said the flue gas desulfurization system, or scrubber, is needed to keep the plant’s two coal-powered units running.

The investment is necessary to comply with changes to federal environmental regulations and the Clean Air Act.

The scrubber will remove up to 95 percent of sulfur dioxide and other emissions from flue gas by mixing it with water and limestone.

The resulting commercial-grade calcium sulfate gypsum will be sold for use in wallboard, cement and as an additive for soil to increase root mass and reduce soil erosion.

The design and engineering work is about 90 percent complete, project manager Jay Weston said, and the overall project is on track for an April 2016 completion.

“This year we’ll finalize the design, finish procuring materials … and get to peak construction,” he said.

On Monday, there were about 520 construction contractors on site as huge fiberglass stack liners were going inside the 70-foot-wide stack shell and support components and two scrubber units — one for each of the plant’s coal-powered units — progressed.

The first scrubber unit is about 95 feet tall so far, Weston said, but it’ll top out at about 125 feet.

Nearby, work also continued on gypsum ponds that will hold the byproduct of the scrubbing process.

The gypsum will travel a little more than a mile via underground pipelines to three ponds to be stored, Weston said. The ponds will have plastic polyurethane liners and will hold the gypsum as it “naturally dewaters,” he said.

The scrubber project will create 24 new full-time jobs, including operators, maintenance technicians, chemists, planners and others, Plant Manager Valerie Wade said.

Plant Daniel has four generation units: two fed by coal and two fed by natural gas. The two coal units supply about 20 percent of Mississippi Power’s 190,000 customers.

Plant Daniel, located on Mississippi Highway 63, employs about 200 full-time workers and can generate 1,000 megawatts of electricity.
