* Note 1:
The health-based concentration limits for appendix VIII part 261 constituents for which a health-based concentration is not provided below is 2xE−06 mg/kg.
Note 2:
The levels specified in this appendix and the default level of 0.002 micrograms per kilogram or the level of detection for constituents as identified in Note 1 of this appendix are administratively stayed under the condition, for those constituents specified in § 266.112(b)(1), that the owner or operator complies with alternative levels defined as the land disposal restriction limits specified in § 268.43 of this chapter for FO39 nonwastewaters. See § 266.112(b)(2)(i).
