Minn. R. 4720.0550
Section 141.21, paragraph (b), clause (1), of the National Primary Drinking Water Regulations is amended to read:
If a routine sample is total coliform-positive, the public water supplier must collect a set of repeat samples within 24 hours of being notified of the positive result. A supplier must collect no fewer than four repeat samples for each total coliform-positive sample found. The commissioner of health may extend the 24-hour limit on a case-by-case basis if the supplier has a logistical problem in collecting the repeat samples within 24 hours and the problem is beyond the supplier's control. In the case of an extension, the commissioner of health shall specify how much time the supplier has to collect the repeat samples.
Section 141.21, paragraph (d), clause (2), of the National Primary Drinking Water Regulations is replaced with the sentence: "Sanitary surveys will be conducted by the department."
Section 141.21, paragraph (e), clause (2), of the National Primary Drinking Water Regulations is deleted.
