    (e)The potential for migration off-site;

     

    (f)The type of contaminant;

     

    (g)The size of the release (number of gallons of regulated substance lost);

     

    (h)Whether the leak is continuing or has been contained;

     

    (i)Whether publicly owned lands are impacted;

     

    (j)The degree to which human health, safety, or welfare may be affected by exposure to the contamination;

     

    (k)The size of the population or area affected by the contamination; and

     

    (l)The time that has elapsed since the release was detected.

     

    6405.2The priority list of sites shall be based on an ordering of scored sites that the highest scored site(s) will be of highest priority for response action and the lowest scored site will be of lowest priority for response action.

     

    6405.3The Director may adjust the priority list as necessary based upon changing environmental conditions, public health needs, cost effectiveness, efficiency, and available resources.

     

    6405.4Regardless of the position of a site on the priority list, the Director may initiate emergency action for those sites that, in the judgment of the Director, present an imminent hazard to human health and safety or where failure to prevent migration of a regulated substance would cause irreversible damage to the environment. Site classification pursuant to § 6206 shall be completed to evaluate the need for additional assessment or development of a corrective action plan.
