(c) In lieu of the soil standards in Table 600-2, the responsible party may develop site-specific soil remediation standards by evaluating the risk to human health and the environment using the methods described in ASTM Standard E 1739-95 (2010)e1 entitled "Standard Guide for Risk-Based Corrective Action Applied at Petroleum Release Sites" (ASTM E 1739-95), or ASTM E 2081, available as noted in Appendix B, as applicable.
(d) Site-specific soil standards developed pursuant to (c), above, shall:
(1) Demonstrate that leaching of contaminants to groundwater will not result in violations of ambient groundwater quality standards as specified in Env-Or 603.03;
(2) Demonstrate that no significant risk to human health and the environment exists at the site pursuant to the procedures prescribed in ASTM E 1739-95 or ASTM E 2081, as applicable, as noted in (c), above; and
(3) In the evaluation of human health in (2), above, use a cumulative risk approach that compares site-specific information to a cumulative risk of an excess lifetime cancer risk of one in 100,000 and a cumulative non-cancer risk that is a hazard index equal to one pursuant to the procedures prescribed in ASTM E 1739-95 or ASTM E 2081, as applicable, as noted in (c), above.
(e) In lieu of the soil standards in Table 600-2, the responsible party may use an activity and use restriction at a site where a department-approved remedial action relies on the restriction of site activities and uses to eliminate exposure pathways to achieve or maintain protection of human health and the environment pursuant to the procedures outlined in Env-Or 608.
(f) The soil standards in Table 600-2 shall not apply at sites where contamination is at or below background levels.
