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.
Table 1 attached to Ordinance 11-97 lists site hazard potential by land use activity (source) on a scale of one (1) to nine (9), with one (1) being a low hazard and nine (9) a very high hazard. This rating is based on the intrinsic hazard posed by different land uses and is related to the materials commonly used or stored on the site or the types and amounts of wastes commonly discharged.
If the two tables referenced above indicated different site hazard potential ratings for the SIC-coded land use activity and the materials found on-site, the higher of the two scores is the rating for the site.
