HRS rule, page 51626, Section 220.127.116.11
18.104.22.168: Observed release of a specific hazardous substance to surface water in-water segment. Section 22.214.171.124.1 specifies the criteria for assigning values to the observed release factor for the ground water to surface water migration component. With regard to an individual hazardous substance, consider an observed release of that hazardous substance to be established for the surface water in-water segment of the ground water to surface water migration component only when the hazardous substance meets the criteria both for an observed release both to ground water (see section 126.96.36.199.1) and for an observed release by chemical analysis to surface water (see section 188.8.131.52.1).
If the hazardous substance meets the section 184.108.40.206.1 criteria for an observed release by chemical analysis to surface water but does not also meet the criteria for an observed release to ground water, do not use any samples of that hazardous substance from the surface water in-water segment in evaluating the factors of this component (for example, do not use the hazardous substance in establishing targets subject to actual contamination or in determining the level of actual contamination for a target).
