Current through Register Vol. 54, No. 25, June 22, 2024
(a) This subchapter establishes treatment technique requirements that include requirements for corrosion control treatment, lead service line replacement and public education. These requirements are triggered, in some cases, by samples collected at consumers' taps which exceed a lead or copper action level.(b) This subchapter applies to community water systems and nontransient noncommunity water systems. For purposes of this subchapter, the systems are classified as either large, medium or small, based on the population served by the system. A large water system serves more than 50,000 persons. A medium water system serves more than 3,300 and fewer than or equal to 50,000 persons. A small water system serves 3,300 or fewer persons.(c) A community or nontransient noncommunity water system which is a consecutive water system shall comply with this subchapter regardless of the compliance status of any public water system from which finished water is obtained. Each interconnection with a public water system from which finished water is obtained is considered source water for the receiving public water system and is subject to the monitoring, corrosion control treatment and source water treatment requirements under this subchapter.
