Each covered public water system shall submit a service line\ninventory, in a format to be developed by the department, that\nidentifies the location, material composition, and other details of all\nservice lines connected to its distribution system. Each covered public\nwater system shall also submit an inventory summary form, in a format to\nbe developed by the department, summarizing the data identified in the\nservice line inventory. Notwithstanding subdivisions three and four of\nthis section, the development of service line inventories and inventory\nsummary forms shall comply with requirements promulgated by the United\nStates environmental protection agency.\n 3. Each service line shall be listed in service line inventories. Each\ncovered public water system shall include for each service line the\ninformation listed in this subdivision. The covered public water system\nmay mark "unknown" where documented evidence is not currently available:\n (a) street address;\n (b) town;\n (c) zip code;\n (d) if known, whether a gooseneck, pigtail, or connector made of lead\nis present;\n (e) if known, the material composition of both the public portion and\ncustomer portion of the service line;\n (f) if known, whether the public portion or customer portion of the\nservice line was ever made of lead;\n (g) the verification method used to determine the material composition\nof both the public portion and customer portion of the service line;\n (h) if known, the installation or replacement date of both the public\nportion and customer portion of the service line;\n (i) if known, the diameter of both the public portion and customer\nportion of the service line;\n (j) if known, whether lead solder is present;\n (k) if known, the building type; and\n (l) if known, whether a point of use or point of entry treatment\nsystem is present.\n 4. Inventory summary forms shall include, but not be limited to, the\nfollowing information about each covered water system:\n (a) water system name and identification number;\n (b) contact information for the owner or licensed operator of record\ncompleting the form;\n (c) the total number of service lines in the distribution system;\n (d) the total number of lead service lines, including the total number\nof lead public service line portions and the total number of lead\ncustomer service line portions;\n (e) the total number of galvanized service lines requiring replacement\nas defined in 40 CFR 141.84, including the total number of galvanized\npublic service line portions requiring replacement and the total number\nof galvanized customer service line portions requiring replacement;\n (f) the total number of non-lead service lines, including the total\nnumber of non-lead public service line portions and the total number of\nnon-lead customer service line portions;\n (g) the total number of service lines of unknown material, including\nthe total number of unknown public service line portions and the total\nnumber of unknown customer service line portions;\n (h) the total number of public service line portions identified by\nhistorical records, field inspections, customer identification with\nphoto or other verification, excavation, sequential sampling,\nstatistical analysis/predictive modeling, or other method determined by\nthe covered public water system to accurately identify service line\nmaterials;\n (i) the total number of customer service portions identified by\nhistorical records, field inspections, customer identification with\nphoto or other verification, excavation, sequential sampling, and\nstatistical analysis/predictive modeling, or other method determined by\nthe covered public water system to accurately identify service line\nmaterials;\n (j) a description of how the service line inventory will be accessible\nto the public; and\n (k) a certification verifying the accuracy of the information.\n 5. Each covered public water system shall electronically submit to the\ndepartment an initial service line inventory and an initial inventory\nsummary form no later than October sixteenth, two thousand twenty-four.\nThe department may prescribe data management means and methods for\nelectronic submissions by covered public water systems for uniformity\npurposes.\n 6. Covered public water systems whose inventories contain any service\nlines classified as lead, galvanized requiring replacement as defined in\n40 CFR 141.84, or unknown shall electronically submit updated service\nline inventories and inventory summary forms to the department at least\nannually. Updated service line inventories and inventory summary forms\nshall reflect information gathered during any service line replacements\nor service line material inspections that may have been conducted.\nUpdated inventory summary forms shall additionally include:\n (a) a description detailing the steps being taken to determine the\nmaterial composition of unknown service lines;\n (b) the total number of service lines classified as lead, galvanized\nrequiring replacement, or unknown that were replaced over the course of\nthe previous year; and\n (c) the total number of service lines classified as unknown that were\ndetermined to be lead, galvanized requiring replacement, or other\nmaterial over the course of the previous year.\n 7. Each covered public water system which operates its own website\nshall make its most recent service line inventory and inventory summary\nform available to the public on its website.\n 8. No later than one hundred twenty days after receiving initial and\nupdated service line inventories and inventory summary forms, the\ndepartment shall make such inventories and inventory summary forms\navailable to the public through the department's website. Each local\nhealth department shall include a link on its website to the website\nmaintained by the department for hosting service line inventories and\ninventory summary forms.\n 9. No later than October sixteenth, two thousand twenty-six, the\ndepartment shall make the information from the service line inventories\nof covered public water systems serving more than ten thousand people\nand fewer than two million people available to the public on the\ndepartment's website in the form of an interactive map or maps. Such\ninteractive map or maps shall include, for each service line:\n (a) material classification, including the material classification of\nboth the public and customer portions of a service line;\n (b) street address; and\n (c) the verification method for the service line classification.\n 10. The department's interactive map or maps shall be searchable by\naddress, and color-coded where applicable to designate material\nclassification. The department's interactive map or maps shall be\nupdated at least annually, in conjunction with the submission of updated\nservice line inventories by covered public water systems. The department\nmay choose not to create an interactive map when a covered public water\nsystem certifies that it maintains and updates its own interactive map,\nand shall include a link to such interactive map on the department's\nwebsite.\n 11. The department shall adopt such rules and regulations as it deems\nnecessary and proper to implement the provisions of this section.\n
