Section 333-061-0560 - Reporting

(1) If the cyanotoxin concentration exceeds a health advisory level in an initial sample 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 analysis begins. Laboratories must report any analysis received from a 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 contracting laboratory as soon as possible but no later than three business days after analysis begins;

(c) For any analytical result used to determine whether an advisory may be lifted pursuant to OAR 333-061-0570(4), laboratories must report results to both 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 or submitted in a format approved by the Authority.

(4) Every sample collected from a raw water sample point, entry point or from the distribution system and analyzed for cyanotoxins by an ORELAP accredited laboratory or the Oregon Department of Environmental Quality using an analysis method identified in OAR 333-061-0550 must be reported to the Authority according to this rule.
