The groundwater protection standard (GWPS) is generally limited to Appendix VIII constituents. Appendix IX constituents not in Appendix VIII can be included in a facility’s GWPS by the omnibus authority of RCRA 3005(c)(3) if the Regional Administrator determines they pose a threat to human health or the environment. Removing an Appendix IX constituent from a facility’s GWPS requires a permit modification. Appendix IX constituents not in Appendix VIII are eligible for a variance or an alternate concentration limit (ACL).
