Money has been approved in Redding to determine the cause of cracks in the foundation of the waste treatment plant.  The Board of Selectmen signed off on $3,300 for Milone and MacBroom to do the initial assessment of the cause and how big of a problem the cracks pose.  A study will be needed to determine scope of repairs, the cost of which has not yet been determined.  Members of the Water Pollution Control Commission, told the selectmen yesterday that it's possible the subsoil has degraded over time since the building was put in in 2008.
