The numerical ranking for the site is at or above the action number. Sites which pose a significant threat to human health or the environment cannot pursue monitoring only as a corrective action option and shall define the areal and vertical extent of soil and groundwater contamination to the applicable cleanup levels upon approval by the Division. However, if the conditions posing a significant threat have been eliminated and adequate justification, with supporting documentation, has been provided to the Division to demonstrate the conditions will not reoccur, the site shall be ranked provided the Division approves ranking at the site. Sites which do not pose a significant threat to human health or the environment, shall begin a corrective action program of monitoring the site in accordance with TGD - 007 Monitoring at UST Sites upon approval by the Division. The owner, operator or responsible party shall complete the site ranking required by this Technical Guidance Document each year and submit with the appropriate monitoring report.
