A multimillion dollar expansion at a Pleasants County chemical plant could bring dozens of new jobs to the Mid-Ohio Valley.

A three-phase expansion at Solvay's Willow Island plant was announced Wednesday.

The work will take place at the Willow Island plant the company acquired when it purchased Cytec in 2015.

The first expansion, a $45 million project, will double the capacity of the plant's HALS production unit. It is expected to be completed in the first quarter of 2019, creating 30 to 40 jobs.

In all, the three expansions are to cost $70 million, to take place over three years.

According to Solvay's corporate website, the Willow Island site is already one of the company's largest manufacturing facilities, supplying global markets in the paint, coatings, adhesives, plastics, automotive and packaging industries.

The Belgian-owned company also employs about 300 people at the former BP-Amoco complex in Marietta that it acquired in 2001. That plant produces compounds for Solvay Specialty Polymer Polysulfones such as RadelⓇand UdelⓇ.
