§ 109.714. Filter profile, filter self-assessment and comprehensive performance evaluations.
Public water systems are required to perform or conduct a filter profile, filter self-assessment or CPE if any individual filter monitoring conducted under § 109.301(1)(iv) (relating to general monitoring requirements) demonstrates one or more of the conditions in paragraphs (1)—(3).
(1) If an individual filter demonstrates a condition under § 109.701(e)(2)(i)or (ii) (relating to reporting and recordkeeping), the public water system shall notify the Department within 24 hours of the individual filter turbidity level exceedance and shall report the obvious reason for the abnormal filter performance. If a system serving 10,000 or more persons is not able to identify the reason for the exceedance, the system shall produce a filter profile within 7 days of the exceedance and report to the Department that a filter profile was produced.
(2) If an individual filter demonstrates a condition under § 109.701(e)(2)(iii),the public water system shall notify the Department within 24 hours of the individual filter turbidity level exceedance, shall conduct a self-assessment of the filter within 14 days of the exceedance and shall report to the Department that a filter self-assessment was conducted. A filter self-assessment shall consist of at least the following components:
(i) Assessment of filter performance.
(ii) Development of a filter profile.
(iii) Identification and prioritization of factors limiting filter performance.
(iv) Assessment of the applicability of corrections.
(v) Preparation of a filter self-assessment report.
(vi) For public water suppliers serving fewer than 10,000 persons, if a self-assessment is required, the public water supplier shall report the date that it was triggered and the date that it was completed.
(3) If an individual filter demonstrates a condition under § 109.701(e)(2)(iv),the public water system shall:
(i) Notify the Department within 24 hours of the turbidity level exceedance.
(ii) Arrange for the conduction of a CPE by the Department no later than 30 days following the turbidity level exceedance.
(iii) Ensure that the CPE is completed and submitted to the Department no later than 90 days following the turbidity level exceedance.
(iv) Instead of subparagraphs (ii) and (iii), for public water systems serving fewer than 10,000 persons:
(A) Arrange for the conduction of a CPE by the Department no later than 60 days following the turbidity level exceedance.
(B) Ensure that the CPE is completed and submitted to the Department no later than 120 days following the turbidity level exceedance.
(C) A new CPE is not required if a CPE was completed by the Department within the previous 12 months, or the system and the Department are jointly participating in a program involving a combination of CPE results as the bases for implementing process control priority-setting techniques and maintaining long-term involvement to systematically train staff and administrators at the system.
(D) If a CPE is required, the public water system shall report that a CPE is required and the date that it was triggered.
