Section 335-7-11-.10 - Monitoring Waivers

A small system that meets the requirements of this rule may apply to the state to reduce the frequency of monitoring for lead and copper to once every nine years.

(a) The system must submit a materials survey showing the system is free of lead and copper containing materials as detailed below.

1. It contains no plastic pipes which contain lead plasticizers, or plastic service lines which contain lead plasticizers; and

2. It is free of lead service lines, lead pipes, lead soldered pipe joints, and leaded brass or bronze alloy fittings and fixtures, unless such fittings and fixtures meet the NSF Standard 61 Section 9.

3. The system contains no copper pipes or copper service lines.

(b) The system must have completed at least one six-month round of standard tap water monitoring for lead and copper demonstrating that the 90th percentile levels for all rounds of monitoring conducted since the system became free of all lead-containing and copper-containing materials were less than or equal to .005 mg/L for lead and 0.65 mg/L for copper.

(c) A system that has been granted a waiver must monitor for lead and copper at the reduced number of monitoring sites specified in Table 11-1 every nine years. The system must also submit a materials survey along with the monitoring results.

(d) A system must return to monitoring for lead and copper at least every three years if the system no longer meets than materials criteria, has a 90th percentile level for lead greater than .005 mg/L or a 90th percentile level for copper greater than .065 mg/L.

(e) The system shall notify the Department within 60 days after determining the system is no longer free of materials that contain lead or copper.
