Current through Vol. 41, No. 19, June 17, 2024

Section 252:730-5-20 - Fish consumption

(a)General. The surface waters of the state shall be maintained so that toxicity does not inhibit ingestion of fish and shellfish by humans. The numerical criteria and values for substances listed in the column "Fish Consumption" in Table 2 of Appendix G of this Chapter shall apply to surface waters designated as Warm Water Aquatic Community, Cool Water Aquatic Community, or Trout Fishery.

(b)Water column criteria to protect for the consumption of fish flesh. The water column numerical criteria (total recoverable) identified in the "Fish Consumption" column in Table 2 of Appendix G protect human health for the consumption of fish, shellfish and aquatic life. Water column numerical criteria to protect human health for human consumption of fish flesh are considered long-term average standards. For purposes of permitting discharges for attainment of these standards, the permitting authority shall use long-term average receiving stream flows and complete mixing of effluent and receiving water to determine appropriate permit limits.

(c)Fish tissue levels. Surface waters of the state shall be maintained to prevent bio-concentration of toxic substances in fish, shellfish, or other aquatic organisms to levels that become a risk to human health.
