PARKERSBURG, W.Va. (AP) — West Virginia emergency officials say a warehouse fire that began last week is nearly out.

Lubeck Fire Chief Mark Stewart estimates that the fire in South Parkersburg is "90 percent" extinguished from ongoing efforts by firefighters.

The goal is to finish overnight Friday and Saturday, then monitor it for up to two days for possible flare-ups.

The 420,000-foot (130,000-meter) warehouse property where the fire broke out Saturday is owned by Columbia, Maryland-based Intercontinental Export Import Inc., which says on its website that it buys and sells an array of recycled plastics worldwide.

The Department of Environmental Protection has been measuring air quality around the site and was expected to post more results later.

The DEP ordered the company to provide a detailed inventory and properly dispose of debris.
