(3) evaluate the need to resample if previous samples exceeded the intervention limits; (4) evaluate the significance of the exceedance and the source or cause of the constituents exceeding the intervention limits; (5) evaluate the need for immediate corrective action to prevent pollutant concentrations from approaching or exceeding standards at the compliance boundary, surface water compliance boundary, or lower compliance boundary; (6) evaluate the need for changes in water monitoring, including sampling frequencies, constituents analyzed, and installation of additional monitoring points; (7) within 30 days after obtaining the sample results in which an intervention limit was exceeded, submit a written report to the commissioner describing the evaluations and conclusions under subitems (2)to (6) and the actions taken or planned under subitem (8); and (8) take other actions described in the facility's contingency action plan and as required in subpart 15 and part 7035.2615. H. In lieu of the intervention limits and standards under items E and F, the commissioner may establish alternative standards and intervention limits in the facility permit as follows: (1) If the concentration of any constituent in the background ground water at a facility is greater than a standard or intervention limit established in this subpart,the background concentration of the constituent must be used as the standard or intervention limit. For purposes of this subitem, background refers to the condition of ground water that has experienced no change in quality due to migration of constituents from the facility. If the background water quality is inadequately defined,the commissioner may require additional evaluation including sampling, statistical analysis of sampling data, and installation of additional monitoring points.The commissioner may alter the alternative standards or intervention limits if background water quality is changing due to actions or events occurring outside the facility property and beyond the owner's or operator's control.
