Universal Citation: 179 NE Admin Rules and Regs ch 17 ยง 002

Current through September 17, 2024

002.01 These regulations establish requirements for filtration and disinfection that are in addition to criteria under which filtration and disinfection are required under 179 NAC 13. The regulations in this chapter establish or extend treatment technique requirements in lieu of maximum contaminant levels for the following contaminants: Giardia lamblia, viruses, heterotrophic plate count bacteria, Legionella, Cryptosporidium, and turbidity. Each surface water system or ground water under the direct influence of surface water system serving at least 10,000 people must provide treatment of its source water that complies with these treatment technique requirements and are in addition to those identified in 179 NAC 13-003. The treatment technique requirements consist of installing and properly operating water treatment processes which reliably achieve:

1. At least 99% (2-log) removal of Cryptosporidium between a point where the raw water is not subject to recontamination by surface water runoff and a point downstream before or at the first customer for filtered systems, or Cryptosporidium control under the wellhead protection program for unfiltered systems.

2. Compliance with the profiling and benchmark requirements under the provisions of 179 NAC 17-004.

002.02 A public water system subject to the requirements of 179 NAC 17 is considered to be in compliance with the requirements of 179 NAC 17-002.01 if:

1. It meets the requirements for avoiding filtration in 179 NAC 13-004 and 179 NAC 17-003 and the disinfection requirements in 179 NAC 13-005 and 17-004; or

2. It meets the applicable filtration requirements in either 179 NAC 13-006 or 179 NAC 17-005 and the disinfection requirements in 179 NAC 13-005 and 179 NAC 17-004.

002.03 Systems are not permitted to begin construction of uncovered finished water storage facilities.

002.04 Systems using surface water or ground water under the direct influence of surface water that did not conduct optional monitoring under 179 NAC 17-004 because they served fewer than 10,000 persons when such monitoring was required, but serve more than 10,000 persons prior to January 14, 2005 must comply with 179 NAC 17-002, 17-003, 17-005, 17-006, and 17-007. These systems must also consult with the Director to establish a disinfection benchmark. A system that decides to make a significant change to its disinfection practice, as described in 179 NAC 17-004.03A items 1 through 3 must consult with the Director prior to making such change.

002.05 All surface water systems must provide filtration.
