Not Much Is Being Said About A Proposed Expansion At Royal Moulding’s Bristol Tennessee Plant. Last Month, The Texas Based Company Has Filed A Construction Permit Application With The Tennessee Department Of Environment And Conservation’s Division Of Air Pollution Control. The Application Is Reportedly For Internal Construction. Bristol Plant Manager Brad Colburn Told The Bristol Herald Courier Newspaper That Expansion Plans Are On The Horizon But Declined To Discuss Them. This Would Be The Fourth Such Expansion In 16 Years.
