Unless I'm mistaken, the data extracted for the quest only records these as "tower" so it doesn't specify if it's a chimney or a communications tower, many of the other data points are for chimneys so I think it's very likely this one is for the chimney.

On the Esri imagery the shadows cast to the west, so if there was a comms tower there you'd expect to see a shadow but there's none, only the chimney.

On Bing to me it just looks like some stockpiled equipment on the ground.

Either way if in doubt probably best to not map it and leave a note or fixme.
