4/9/2020 Gastineau, Janet <[email protected]> Mon, Apr 6, 9:18 AM (3 days ago) to Mike, Kyle FOr determining compliance with the requirement to keep the percent of readings less than or equal to 0.3 NTU you only need to count the 15 minute CFE readings, not what happens between them. So if the highest of the 15 minute readings was not this value, please revise the MOR and resubmit. Thanks!

Should we use one of the 96 readings for the daily highest?

According to this, there should be at least one 15 minute reading included. Please make the correction to the turbidity data page 1 of 2 and submit it no later than 4/10/2020.
