Idaho Department of Environmental Quality

The Idaho Department of Environmental Quality will be notified of your planned excavation.   IDEQ’s Dig Line membership covers select environmental cleanup sites which leave behind low levels of contamination in soil or groundwater, which pose little risk if managed properly.  In the interest of health and safety IDEQ sometimes imposes conditions on excavation or the handling of excavated materials at these sites.   If, after reviewing your planned excavation, IDEQ believes the excavation affects one of these sites and will trigger such conditions, they will make every attempt to notify you via phone, fax, or e-mail. If you do not hear from IDEQ you may assume that there is not an issue with the proposed excavation.  IDEQ also recommends that you search the IDEQ Facility Mapper at for your area of excavation, by searching by address or using the pan/zoom tools, to find any cleanup sites and the associated IDEQ contact information.
