 Essex Junction City Councilors have not yet made a decision on a request for more sound waivers for the Champlain Valley Expo. Officials at the Expo want to upgrade the aging concert venue to help attract bigger artists. Part of that includes getting more waivers to allow for excessive noise. 20 are approved now, but the Expo is looking for 15 more. They presented a plan Wednesday night, but City Councilors want to get more public feedback before making a decision.
