(b) School officials shall use sampling protocols in subsection (2) of this section to collect samples in all schools from:
(i) No less than twenty-five percent of each type and age of plumbing fixture which is not a "very low lead" plumbing fixture; and
(ii) No less than ten percent of each type of plumbing fixture which is a "very low lead" plumbing fixture.
(c) Schools that are Group A public water systems are not required to do ongoing lead monitoring required by (a) of this subsection if the schools meet the lead monitoring requirements in chapter 246-290 WAC.
(5) Corrective actions. School officials shall:
(a) For all plumbing fixtures with sample results of lead above 0.020 milligrams per liter or 20.0 parts per billion, immediately shut off these fixtures or make them inoperable.
(b) For all plumbing fixtures of the same type and age as any fixture with results above 0.020 milligrams per liter or 20.0 parts per billion:
(i) Take immediate corrective action according to (a) of this subsection; or
(ii) Collect first draw samples within ten business days. Upon receipt of sample results, immediately shut off or make inoperable all plumbing fixtures with results of lead above 0.020 milligrams per liter or 20.0 parts per billion.
(c) To provide drinking water at the location of these fixtures, take one or more of the following remedies:
(i) Bottled water. If bottled water is used, provide bottled water that is produced by a Washington state department of agriculture-approved bottling operation or out-of-state or international bottler whose product meets federal Food and Drug Administration regulations.
(ii) Manual flushing. Manual flushing may be used only as a temporary remedy. If manual flushing is used:
(A) Take flush samples from twenty-five percent of each type and age of the fixtures planned to be included in the flushing program to determine the flushing time necessary to reduce lead to below 0.020 milligrams per liter or 20.0 parts per billion. Start by following the sample collection protocol of first-draw samples described in subsection (2)(b) of this section with the addition of letting the water run for thirty seconds before filling the bottle.
(B) Open the tap of every fixture included in the flushing program every morning before the school facility opens and let the water run for the length of time established in (c)(ii)(A) of this subsection.
(iii) Automated flushing. If automated flushing is used, take samples from twenty-five percent of each type and age of the fixtures included in the flushing program to demonstrate that the automated system reduces lead to below 0.020 milligrams per liter or 20.0 parts per billion.
(iv) Fixture replacement. If individual plumbing fixtures are replaced:
(A) Precondition the new plumbing fixtures by running water through the fixture continuously for twenty-four hours; and
(B) Collect first draw samples after preconditioning and verify sample results of lead below 0.020 milligrams per liter or 20.0 parts per billion. If the preconditioned plumbing fixture does not yield a sample result below this level, (a) of this subsection applies.
(v) Treatment. Before treatment is used, submit an engineering project report to the department, per WAC 246-290-110. Installation of treatment devices will result in the school's designation as a public water supply. School officials shall then ensure they comply with the Group A public water system rules and regulations, chapter 246-290 WAC and water works operator certification rules and regulations, chapter 246-292 WAC.
(6) Notification requirements. School officials shall:
(a) Notify school facility staff, students, parents, and the local health officer within five business days of the school officials receiving lead sampling results above 0.020 milligrams per liter or 20.0 parts per billion.
(b) Make all results available for review upon request.
