A week after Hall County gave its written response to residents sickened by the smell of decaying food waste at a landfill, county officials consider the case looked into, investigated and closed, complete with remedial steps. The county’s review and response, written by County Administrator Randy Knighton and released on Nov. 19, acknowledges zoning laws were broken, but it doesn’t mention who broke the laws and what county officials did and didn’t do to help. None of the Hall County commissioners returned one of several attempts to reach them for comment on Monday.
