The state Department of Environmental Protection will take air-quality readings in Monessen in advance of the restarting of a coke works that is expected to provide 160 jobs in the city.
The air sampling will continue after ArcelorMittal resumes operations at the plant formerly owned by Wheeling-Pittsburgh Steel Corp. as the DEP considers the need for permanent air monitoring around the operation, department spokesman John Poister said.
A mobile analytical unit already is in the city to gather readings. The unit detects small changes in air quality and has the ability to sample for a large number of compounds.
The plant could open later this week, Poister said.
It has been on “hot idle” status since it last operated in May 2009, he said.
