§ 1114-b. Service line inventories and mapping. 1. Definitions. For
the purposes of this section:

(a) "Service line" means any piping connecting a water main to a
building inlet.

(b) "Gooseneck, pigtail, or connector" means a short section of
piping, typically not exceeding two feet, which can be bent and used for
connections between rigid portions of a service line, as defined in 40
CFR 141.2.

(c) "Galvanized service line" means iron or steel piping that has been
dipped in zinc to prevent corrosion and rusting.

(d) "Covered public water system" means (i) a public water system that
serves at least fifteen service connections used by year-round residents
or regularly serves at least twenty-five year-round residents; or (ii) a
public water system that regularly serves at least twenty-five of the
same people, four hours or more per day, for four or more days per week,
for twenty-six or more weeks per year.

2. Each covered public water system shall submit a service line
inventory, in a format to be developed by the department, that
identifies the location, material composition, and other details of all
service lines connected to its distribution system. Each covered public
water system shall also submit an inventory summary form, in a format to
be developed by the department, summarizing the data identified in the
service line inventory. Notwithstanding subdivisions three and four of
this section, the development of service line inventories and inventory
summary forms shall comply with requirements promulgated by the United
States environmental protection agency.

3. Each service line shall be listed in service line inventories. Each
covered public water system shall include for each service line the
information listed in this subdivision. The covered public water system
may mark "unknown" where documented evidence is not currently available:

(a) street address;

(b) town;

(c) zip code;

(d) if known, whether a gooseneck, pigtail, or connector made of lead
is present;

(e) if known, the material composition of both the public portion and
customer portion of the service line;

(f) if known, whether the public portion or customer portion of the
service line was ever made of lead;

(g) the verification method used to determine the material composition
of both the public portion and customer portion of the service line;

(h) if known, the installation or replacement date of both the public
portion and customer portion of the service line;

(i) if known, the diameter of both the public portion and customer
portion of the service line;

(j) if known, whether lead solder is present;

(k) if known, the building type; and

(l) if known, whether a point of use or point of entry treatment
system is present.

4. Inventory summary forms shall include, but not be limited to, the
following information about each covered water system:

(a) water system name and identification number;

(b) contact information for the owner or licensed operator of record
completing the form;

(c) the total number of service lines in the distribution system;

(d) the total number of lead service lines, including the total number
of lead public service line portions and the total number of lead
customer service line portions;

(e) the total number of galvanized service lines requiring replacement
as defined in 40 CFR 141.84, including the total number of galvanized
public service line portions requiring replacement and the total number
of galvanized customer service line portions requiring replacement;

(f) the total number of non-lead service lines, including the total
number of non-lead public service line portions and the total number of
non-lead customer service line portions;

(g) the total number of service lines of unknown material, including
the total number of unknown public service line portions and the total
number of unknown customer service line portions;

(h) the total number of public service line portions identified by
historical records, field inspections, customer identification with
photo or other verification, excavation, sequential sampling,
statistical analysis/predictive modeling, or other method determined by
the covered public water system to accurately identify service line
materials;

(i) the total number of customer service portions identified by
historical records, field inspections, customer identification with
photo or other verification, excavation, sequential sampling, and
statistical analysis/predictive modeling, or other method determined by
the covered public water system to accurately identify service line
materials;

(j) a description of how the service line inventory will be accessible
to the public; and

(k) a certification verifying the accuracy of the information.

5. Each covered public water system shall electronically submit to the
department an initial service line inventory and an initial inventory
summary form no later than October sixteenth, two thousand twenty-four.
The department may prescribe data management means and methods for
electronic submissions by covered public water systems for uniformity
purposes.

6. Covered public water systems whose inventories contain any service
lines classified as lead, galvanized requiring replacement as defined in
40 CFR 141.84, or unknown shall electronically submit updated service
line inventories and inventory summary forms to the department at least
annually. Updated service line inventories and inventory summary forms
shall reflect information gathered during any service line replacements
or service line material inspections that may have been conducted.
Updated inventory summary forms shall additionally include:

(a) a description detailing the steps being taken to determine the
material composition of unknown service lines;

(b) the total number of service lines classified as lead, galvanized
requiring replacement, or unknown that were replaced over the course of
the previous year; and

(c) the total number of service lines classified as unknown that were
determined to be lead, galvanized requiring replacement, or other
material over the course of the previous year.

7. Each covered public water system which operates its own website
shall make its most recent service line inventory and inventory summary
form available to the public on its website.

8. No later than one hundred twenty days after receiving initial and
updated service line inventories and inventory summary forms, the
department shall make such inventories and inventory summary forms
available to the public through the department's website. Each local
health department shall include a link on its website to the website
maintained by the department for hosting service line inventories and
inventory summary forms.

9. No later than October sixteenth, two thousand twenty-six, the
department shall make the information from the service line inventories
of covered public water systems serving more than ten thousand people
and fewer than two million people available to the public on the
department's website in the form of an interactive map or maps. Such
interactive map or maps shall include, for each service line:

(a) material classification, including the material classification of
both the public and customer portions of a service line;

(b) street address; and

(c) the verification method for the service line classification.

10. The department's interactive map or maps shall be searchable by
address, and color-coded where applicable to designate material
classification. The department's interactive map or maps shall be
updated at least annually, in conjunction with the submission of updated
service line inventories by covered public water systems. The department
may choose not to create an interactive map when a covered public water
system certifies that it maintains and updates its own interactive map,
and shall include a link to such interactive map on the department's
website.

11. The department shall adopt such rules and regulations as it deems
necessary and proper to implement the provisions of this section.
