			 collected at any entry point or distribution system location in accordance with
			 OAR 333-061-0540, the water supplier must report the result to the Authority
			 and all purchasing systems served by the water supplier as soon as possible but
			 no later than 24 hours after receiving the results.
(2) If the cyanotoxin concentration exceeds a
			 health advisory level in a confirmation sample collected at the entry point in
			 accordance with OAR 333-061-0540(2), the water supplier must report the result
			 to the Authority and all purchasing systems served by the water supplier as
			 soon as possible but no later than eight hours after receiving the
			 results.
(3) Water suppliers must
			 ensure that laboratories follow the reporting requirements as follows:
(a) Laboratories using EPA method 546 or the
			 DEQ Method for Determination of Cyanotoxins in Raw and Finished Water by ELISA
			 Method must validate results and report any analysis that exceeds a health
			 advisory level directly to the Authority and to the water supplier as soon as
			 possible but no later than two business days after analysis begins.
			 Laboratories using EPA method 545 must validate results and report any analysis
			 that exceeds a health advisory level directly to the Authority and to the water
			 supplier as soon as possible but no later than three business days after

			 subcontracted laboratory directly to the Authority and the water supplier
			 within one business day after receiving the validated results;
(b) Subcontracted laboratories using EPA
			 method 546 or the DEQ Method for Determination of Cyanotoxins in Raw and
			 Finished Water by ELISA Method must validate results and report any analysis
			 that exceeds a health advisory level directly to the contracting laboratory as
			 soon as possible but no later than two business days after analysis begins.
			 Subcontracted laboratories using EPA method 545 must validate results and
			 report any analysis that exceeds a health advisory level directly to the

			 Authority and the water supplier within one business day of sample validation
			 by the laboratory;
(d) For any
			 entry point sample result collected in response to a raw water sample result
			 with a detection greater than or equal to 0.20 µg/L for total
			 microcystins or 0.30 µg/L for cylindrospermopsin, laboratories must
			 report results to both the Authority and the water supplier within one business
			 day of sample validation by the laboratory;
(e) For any analytical result with a
			 detection greater than or equal to 0.20 µg/L for total microcystins or
			 0.30 µg/L for cylindrospermopsin, laboratories must report results to the
			 Authority and the water supplier within one business day of sample validation
			 by the laboratory;
(f) For all
			 other analytical results with no detection or with total microcystins detected
			 at less than 0.20 µg/L or cylindrospermopsin detected at less than 0.30
			 µg/L, laboratories must report results to the Authority within 10 days of
			 the end of the month in which the sample was collected; and
(g) Analyses required by OAR 333-061-0540  must be uploaded by the laboratory to the Authority in an approved XML format
