OAR 333-061-0520
Definitions

In addition to the definitions in OAR 333-061-0020 (Definitions), the following definitions apply to OAR 333-061-0510 (Applicability of Cyanotoxin Rules) to 333-061-0580 (Record Keeping):
(1) “Confirmation sample” means a water sample taken after exceeding a health advisory level at the entry point on a different day but the same location.
(2) “Cyanobacteria” are photosynthetic bacteria that share some properties with algae and are found naturally in freshwater and saltwater. Some species of cyanobacteria can produce toxins, which are known to be harmful to human health above certain concentrations.
(3) “Cyanotoxins” means total microcystins and cylindrospermopsin produced by cyanobacteria.
(4) “Detected” or “detection” means an analytical result that is equal to or greater than the reporting limit for the analytical method being used.
(5) “Distribution sampling points” means representative points in the distribution system.
(6) “Entry point” means a location where water is introduced into the distribution system of a public water system and intended for distribution and consumption without further treatment, except as necessary to maintain water quality in the distribution system, such as for example, booster chlorination. This location is a regulatory point where water is known to be fully treated and does not refer to the point at which water is delivered to a purchasing water system.
(7) “Harmful algal bloom” means a dense colony of cyanobacteria that can rapidly multiply in surface waters when environmental conditions are favorable for growth.
(8) “Health advisory level” is the concentration of a cyanotoxin determined by the US Environmental Protection Agency, as specified in OAR 333-061-0530 (Health Advisory Levels)(1), at or below which adverse health effects are not expected to occur if consuming water containing cyanotoxins at this concentration for up to 10 days.
(9) “Monitoring” means collecting a sample, having it analyzed by an accredited lab, and ensuring results are reported to the Authority.
(10) “Raw water sampling point” means a sampling point on a water source intake in use prior to any treatment, or another raw water sampling point acceptable to the Authority.
(11) “Recreational use health advisory” means a health advisory issued by the Authority for a water body when cyanotoxins are determined to be above any recreational use value for total microcystins, cylindrospermopsin, saxitoxin, or anatoxin-a.
(12) “Vulnerable people” means infants, children under the age of six, pregnant women, nursing mothers, those with pre-existing liver conditions, and those receiving dialysis treatment.
