1174.07 HAZARD POTENTIAL RANKING SYSTEM FOR NON- CONFORMING USES.
   (a)   Any existing uses legally storing, handling using and/or producing Regulated or Hazardous Substances in amounts equal to or less than the requirements under section 1174.06 are considered conforming uses and this section does not apply. Any new use or change of uses shall maintain the conforming status of the property.
   (b)   Existing non-conforming uses shall be permitted to maintain the reported maximum quantity for each reportable Regulated or Hazardous Substance, as determined by peak business cycle. Existing uses and maximum quantities, in combination with a hazard potential rating shall run with the land and be administered in conformance with all other applicable non-conforming provisions of the Village of Granville Code.
   (c)   In order to assess the risk for potential groundwater contamination, a hazard ranking has been developed for various activities categorized by their Standard Industrial Classification (SIC) code. This ranking is based on the kind of materials commonly associated with each use looking only at the most critical hydrologic factors. This ranking, published and updated regularly by the USEPA, is hereby incorporated by reference.
