"Noise pollution" means noise emitted from any excessive noise source in excess of the maximum permissible sound levels.
"Off-hour roadwork" means any roadway construction between the hours of 6:00 p.m. and 7:00 a.m., which would require a variance from the director. For the purpose of this definition, roadway construction shall be limited to any activity, necessary or incidental to reconstruction or resurfacing of public or private highways or roads.
