(B) In addition
to the reporting and recordkeeping requirements in paragraph (1)(d)(A) of this
rule, a public water system which provides conventional filtration treatment or
direct filtration serving at least 10,000 people must report monthly to the
Authority the information specified in subparagraphs (1)(d)(B)(i) and (ii) of
this rule. Public water systems which provide filtration treatment other than
conventional filtration treatment, direct filtration, slow sand filtration, and
diatomaceous earth filtration, regardless of population served, must also meet
the requirements of paragraph (1)(d)(A) of this rule and must report monthly to
the Authority the information specified in subparagraph (1)(d)(B)(i) of this
rule. For the purposes of this rule, filter profile means a graphical
representation of individual filter performance, based on continuous turbidity
measurements or total particle counts versus time for an entire filter run,
from start-up to backwash inclusively, that includes an assessment of filter
performance while another filter is being backwashed.
(i) Turbidity measurements as required by OAR
333-061-0036(5) must be reported within 10 days after the end of each month the
system serves water to the public. Information that must be reported includes:
(I) The total number of filtered water
turbidity measurements taken during the month;
(II) The number and percentage of filtered
water turbidity measurements taken during the month which are less than or
equal to the turbidity limits specified by OAR 333-061-0030(3)(b)(A) through
(D);
(III) The date and value of
any turbidity measurements taken during the month which exceed 1 NTU for
systems using conventional filtration treatment or direct filtration, or which
exceed the maximum level set by the Authority specified in OAR
333-061-0030(3)(b)(D).
(IV) The
date and value of any turbidity measurements taken during the month which
exceed 5 NTU for systems using slow sand filtration or diatomaceous earth
filtration.
(ii) Water
systems must maintain the results of individual filter monitoring for at least
three years. Water systems must report that they have conducted individual
filter turbidity monitoring within 10 days after the end of each month the
system serves water to the public. Water systems must also report individual
filter turbidity measurement results within 10 days after the end of each month
the system serves water to the public only if measurements demonstrate one or
more of the conditions in subparagraphs (1)(d)(B)(ii)(I) through (IV) of this
rule. Water systems that use lime softening may apply to the Authority for
alternative exceedance levels for the levels specified in subparagraphs
(1)(d)(B)(ii)(I) through (IV) of this rule if the water system can demonstrate
that higher turbidity levels in individual filters are due to lime carryover
only and not due to degraded filter performance.
(I) For any individual filter that has a
measured turbidity level of greater than 1.0 NTU in two consecutive
measurements taken 15 minutes apart, the water system must report the filter
number, the turbidity measurement, and the date(s) on which the exceedance
occurred. In addition, the water system must either produce a filter profile
for the filter within seven days of the exceedance (if the water system is not
able to identify an obvious reason for the abnormal filter performance) and
report that the profile has been produced or report the obvious reason for the
exceedance.
(II) For any individual
filter that has a measured turbidity level of greater than 0.5 NTU in two
consecutive measurements taken 15 minutes apart at the end of the first four
hours of continuous filter operation after the filter has been backwashed or
otherwise taken offline, the system must report the filter number, the
turbidity, and the date(s) on which the exceedance occurred. In addition, the
system must either produce a filter profile for the filter within seven days of
the exceedance (if the system is not able to identify an obvious reason for the
abnormal filter performance) and report that the profile has been produced or
report the obvious reason for the exceedance.
(III) For any individual filter that has a
measured turbidity level of greater than 1.0 NTU in two consecutive
measurements taken 15 minutes apart at any time in each of three consecutive
months, the water system must report the filter number, the turbidity
measurement, and the date(s) on which the exceedance occurred. In addition, the
water system must conduct a self-assessment of the filter within 14 days of the
exceedance and report that the self-assessment was conducted. The self
assessment must consist of at least the following components: assessment of
filter performance; development of a filter profile; identification and
prioritization of factors limiting filter performance; assessment of the
applicability of corrections; and preparation of a filter self-assessment
report.
(IV) For any individual
filter that has a measured turbidity level of greater than 2.0 NTU in two
consecutive measurements taken 15 minutes apart at any time in each of two
consecutive months, the water system must report the filter number, the
turbidity measurement, and the date(s) on which the exceedance occurred. In
addition, the water system must arrange to have a CPE by the Authority or a
third party approved by the Authority conducted no later than 30 days following
the exceedance and have the evaluation completed and submitted to the Authority
no later than 90 days following the exceedance.
(iii) If at any time the turbidity exceeds 1
NTU in representative samples of filtered water in a system using conventional
filtration treatment or direct filtration, the system must inform the Authority
as soon as possible, but no later than the end of the next business
day.
(iv) If at any time the
turbidity in representative samples of filtered water exceed the maximum level
set by the Authority as specified in OAR 333-061-0030(3)(b)(D) for filtration
technologies other than conventional filtration treatment, direct filtration,
slow sand filtration, or diatomaceous earth filtration, the water system must
inform the Authority as soon as possible, but no later than the end of the next
business day.
(C) In
addition to the reporting and recordkeeping requirements in paragraph (1)(d)(A)
of this rule, a public water system which provides conventional filtration
treatment or direct filtration treatment serving less than 10,000 people must
report monthly to the Authority the information specified in subparagraphs
(1)(d)(B)(i) of this rule and the information specified in subparagraph
(1)(d)(D) of this rule. Public water systems which provide filtration treatment
other than conventional filtration treatment, direct filtration, slow sand
filtration, and diatomaceous earth filtration regardless of population served
must also meet the requirements of paragraph (1)(d)(A) of this rule and must
report monthly to the Authority the information specified in subparagraph
(1)(d)(B)(i) of this rule.
(D)
Water systems must maintain the results of individual filter monitoring for at
least three years. Water systems must report that they have conducted
individual filter turbidity monitoring within 10 days after the end of each
month the system serves water to the public. Water systems must also report
individual filter turbidity measurement results within 10 days after the end of
each month the system serves water to the public only if measurements
demonstrate one or more of the conditions in subparagraphs (1)(d)(D)(i) through
(iii) of this rule. Water systems that use lime softening may apply to the
Authority for alternative exceedance levels for the levels specified in
subparagraphs (1)(d)(D)(i) through (iii) of this rule if the water system can
demonstrate that higher turbidity levels in individual filters are due to lime
carryover only and not due to degraded filter performance.
(i) If the turbidity of an individual filter
(or the turbidity of the combined filter effluent (CFE) for systems with two or
less filters that monitor CFE in lieu of individual filter monitoring) is
greater than 1.0 NTU in two consecutive measurements taken 15 minutes apart,
the water system must report to the Authority by the 10th day of the following
month the filter number(s), the turbidity value(s) that exceeded 1.0 NTU, the
corresponding date(s) of occurrence, and the cause (if known) for the elevated
turbidity values. The Authority may request the water system produce a
turbidity profile for the filter(s) in question.
(ii) If the turbidity of an individual filter
(or the turbidity of the combined filter effluent (CFE) for systems with two or
less filters that monitor CFE in lieu of individual filter monitoring) is
greater than 1.0 NTU in two consecutive measurements taken 15 minutes apart for
three consecutive months, the water system must conduct a filter
self-assessment within 14 days of the date the turbidity exceeded 1.0 NTU
during the third month, unless a CPE is performed in lieu of a filter
self-assessment. Systems with two filters monitoring the CFE must conduct a
filter self-assessment for both filters. The self-assessment must consist of
the following components: assessment of filter performance; development of a
filter profile as defined in paragraph (1)(d)(B) of this rule; identification
and prioritization of factors limiting filter performance; assessment of the
applicability of corrections; and preparation of a filter self-assessment
report. When a self-assessment is required, the water system must report the
date the self-assessment was triggered, the date the self-assessment was
completed, and the conclusion(s) of the self-assessment by the 10th of the
following month or 14 days after the self-assessment was triggered only if the
self-assessment was triggered during the last four days of the month.
(iii) If the turbidity of an individual
filter (or the turbidity of the combined filter effluent (CFE) for systems with
two or less filters that monitor CFE in lieu of individual filter monitoring)
is greater than 2.0 NTU in two consecutive measurements taken 15 minutes apart
for two consecutive months, the water system must report these turbidity
results to the Authority by the 10th of the following month and arrange to have
a CPE by the Authority or a third party approved by the Authority conducted
within 60 days of the date the turbidity exceeded 2.0 NTU during the second
month. The CPE report must be submitted to the Authority no later than 120 days
following the date the turbidity exceeded 2.0 NTU during the second month. A
CPE is not needed if the Authority or approved third party has conducted a CPE
within the last 12 months or the Authority and the water system are jointly
participating in an on-going Comprehensive Technical Assistance (CTA) project
as part of the Composite Correction Program with the water system. When a CPE
is required, the water system must report that a CPE is required and the date
that the CPE was triggered by the 10th day of the following month.
(e) The water supplier
for water systems using a surface water source or a groundwater source under
direct influence of a surface source which does not provide filtration
treatment shall report according to subsection (1)(d) of this rule in addition
to the requirements of this subsection. Monthly reporting must begin no later
than six months after the Authority determines a source to be GWUDI.
