(a) shall contain no substances, whether alone or in combination with other substances, that are toxic, carcinogenic, mutagenic or teratogenic, other than those of natural origin, at levels and conditions which pose an unreasonable risk to the public health;(b) shall contain no other constituents at levels and conditions which pose an unreasonable risk to the public health;(c) shall not discharge to surface water causing a violation of surface water quality criteria or biological integrity; and(d) naturally occurring levels as used in subparagraph (a) of this paragraph shall include the natural minerals, mining wastes, and the reaction products of oxidation and reduction associated with these materials in Unusable Ground Water in an Acid Production Zone from Mining Activities. These substances shall not pose an unreasonable public health or safety risk to the public. Physical barriers and institutional controls satisfy that requirement.Tenn. Comp. R. & Regs. 0400-40-03-.08
