Is This Guide for Me?
The Stage 1 Disinfectants and Disinfection Byproducts Rule (Stage 1 DBPR) applies to water systems that add a chemical
disinfectant such as chlorine, chloramine, chlorine dioxide, or ozone to their drinking water during any part of the treatment process.
In addition to the basic requirements for all systems that add a chemical disinfectant (covered in the Complying With the Stage 1
Disinfectants and Disinfection Byproducts Rule: Basic Guide EPA Doc. No. 816-B-05-004), this guide covers the additional
requirements for:
Community water systems (CWSs) and non-transient non-community
water systems (NTNCWSs) adding chlorine dioxide during any part of
the treatment process;
Transient non-community water systems (TNCWSs) adding chlorine
dioxide during any part of the treatment process; and
CWSs and NTNCWSs adding ozone during any part of the treatment
process.
Stop!
If you do not add a chemical disinfectant
to your water, the Stage 1 DBPR does not
apply to your system. If you do not use
chlorine dioxide or ozone, the
requirements covered in this supplement
do not apply to your system.
Systems that will typically find this guide useful (if they use chlorine dioxide or ozone) include:
Small towns Home owners' associations
Rural water districts Small private systems
Tribal systems Factories, religious institutions, and schools
Manufactured housing communities with their own water supplies
Subpart H systems that use conventional filtration should obtain Supplement B of this guide or contact their state. Contact
information for Safe Drinking Water Act (SDWA) Primacy Agencies is provided in Appendix E. Tribal contact information is provided
in Appendix F. If your system is a new system or if you are just starting to use a disinfectant, you should work with your state to
determine which requirements apply to you. Your state can also help you figure out how to calculate compliance with the Rule.

Monitoring Requirements for Chlorine Dioxide and Chlorite
DO I HAVE TO MONITOR FOR CHLORINE DIOXIDE AND CHLORITE?
All systems (including TNCWSs) that add chlorine dioxide for disinfection or oxidation must monitor for chlorine dioxide and comply with
the maximum residual disinfectant level (MRDL) listed in Table 2 (40 CFR 141.65). In addition, all CWSs and NTNCWSs using chlorine
dioxide to disinfect or oxidize their water must monitor for chlorite and comply with the maximum contaminant level (MCL) listed in Table 3
(40 CFR 141.64). If you use chlorine dioxide intermittently, you only have to monitor on days or in months when you use it. If you do not
use chlorine dioxide to oxidize or disinfect, this section does not apply to you. Unlike chlorite, excessive levels of chlorine dioxide
can cause acute (i.e., immediate) health effects. Because of this, TNCWSs are required to comply with the chlorine dioxide MRDL even
though they serve transient customers.

Table 3: Chlorite MCL
HOW OFTEN DO I HAVE TO SAMPLE AND WHERE DO I TAKE THE SAMPLES?
Routine and Additional Monitoring
Chlorine Dioxide. Routine monitoring for chlorine dioxide requires one sample per day
taken at the entry point to the distribution system (EPTDS). If a sample exceeds the
MRDL, you must take three additional samples in the distribution system the following
day. Table 4 will help you determine how often you have to sample and how your
system characteristics determine where you must take these samples (40 CFR
141.132(c)(2)(i)). These requirements apply to TNCWSs as well as CWSs and
NTNCWSs.
Chlorite. Routine monitoring for chlorite requires one daily sample at the EPTDS as well as three monthly distribution system samples.
Table 4 explains where to take these samples. If any daily sample exceeds the MCL, you must take additional samples in the
distribution system the following day (40 CFR 141.132(b)(2)(i)). These requirements apply only to CWSs and NTNCWSs. TNCWSs are
not required to monitor for chlorite because it usually causes negative health effects only after long-term exposure.

There is no reduced monitoring for chlorine dioxide (40 CFR 141.132(c)(2)(iii)) or for daily chlorite monitoring (40 CFR
Monthly chlorite monitoring can be reduced to quarterly monitoring after one year of sampling (with prior written permission from the
state) if:
No individual sample taken in the distribution system exceeded the chlorite MCL; and
No individual daily sample taken at the EPTDS exceeded the chlorite MCL.
You must return to routine monitoring if any of your samples (quarterly or daily) exceed the MCL (40 CFR 141.132(b)(2)(iii)(B)).

Supplement A - 8
-------
HOW DO I DETERMINE COMPLIANCE?
Chlorine Dioxide. There are two types of chlorine dioxide violations: acute and non-acute.
Acute violations occur when any routine daily sample taken at the EPTDS exceeds the MRDL and one or more of the samples taken
in the distribution system the following day also exceeds the MRDL (i.e., exceedance of chlorine dioxide in the distribution system).
Failure to take any one of the required additional samples in the distribution system on the day following an exceedance of
the chlorine dioxide (MRDL) at the entry point is also an acute MRDL violation (40 CFR 141.133(c)(2)(i)). For example:
System A's routine EPTDS sample was 0.90 mg/L (> MRDL).
System A's additional distribution system samples the following day were 0.80 mg/L, 0.70 mg/L, and 0.90 mg/L.
System A has committed an acute MRDL violation because one of its additional distribution system samples exceeded
the MRDL.
Non-acute violations occur when two consecutive routine daily entry point samples exceed the MRDL, but none of the additional
samples taken in the distribution system are above the MRDL (i.e., exceedance of chlorine dioxide at the EPTDS, but not in the
distribution system.). Failure to collect the routine entry point sample on the day following an exceedance of the chlorine
dioxide MRDL at the entry point is also a non-acute MRDL violation (40 CFR 141.133(c)(2)(ii)). For example:
System A's routine EPTDS sample was 0.90 mg/L (> MRDL).
System A's routine EPTDS sample on the following day was also 0.90 mg/L, and System A's additional distribution
system samples taken the same day (because of the initial exceedance) were 0.80 mg/L, 0.70 mg/L, and 0.60 mg/L.
System A's routine EPTDS sample on the third day was 0.10 mg/L.
System A has committed a non-acute MRDL violation because two consecutive routine EPTDS samples exceeded the
MRDL, but none of the additional distribution system samples exceeded the MRDL.
Supplement A - 9
-------
Chlorite. Compliance for chlorite monitoring is based exclusively on the average of the 3-sample set taken in the distribution system.
Daily samples must also be taken. If the average of any 3-sample set (either your routine monthly sample set or an additional set taken
due to a daily exceedance) exceeds the MCL, your system has violated the MCL. Even if your routine daily entry point monitoring
result exceeds the MCL and one or more of your additional distribution system samples exceeds the MCL. you are not in
violation unless the average of your three additional distribution system sample exceeds the MCL (40 CFR 141.133(b)(3)).

You have an MCL or MRDL violation if:
Acute violation:
Your routine daily entrance point result is > 0.8 mg/L, and either:
1 . Any additional distribution system sample is > 0.8 mg/L; or,
2. You fail to take any of the additional samples in the distribution
system.
Non-acute violation:
1 . Two consecutive routine daily entry point samples are > 0.8
mg/L, but distribution system samples are < 0.8 mg/L.
2. Your daily sample is > 0.8 mg/L, and you fail to take your
required routine entry point daily sample the next day.
You have an MCL or MRDL violation if:
The average of any 3-sample set is > 1 .0 mg/L.
Note: If your daily entry point sample is above the MCL, you are not
in violation unless the average of your 3 additional distribution
system samples is above the MCL.

Monitoring Requirements for Bromate
DO I HAVE TO MONITOR FOR BROMATE?
Table 6: Bromate MCL
If your system uses ozone for disinfection or oxidation, you must monitor for bromate, a byproduct of
ozonation, and comply with the MCL listed in Table 6 (40 CFR 141.64). A system may choose to monitor
for bromide in order to reduce bromate monitoring and thereby reduce their overall monitoring costs.
DBF
Bromate
MCL (mg/L)
0.010
HOW OFTEN DO I HAVE TO SAMPLE?
Routine and Increased Monitoring
You must take one sample per month for each treatment plant using ozone while the ozonation system is operating under normal
conditions (40 CFR 141.132(b)(3)(i)). There is no increased monitoring for bromate.
Reduced Monitoring
Systems using ozone may reduce their bromate monitoring (with prior written state permission), and thereby reduce overall monitoring
costs, to once per quarter by monitoring for bromide in source water for twelve consecutive months. Because bromate is formed from
bromide, low levels of bromide in your source water indicate low levels of bromate in you treated water. If your running annual average
(RAA) for bromide is < 0.05 mg/L, you may be eligible for reduced bromate monitoring. Contact your state for more information.
If you qualify for reduced monitoring, you must continue to monitor for bromide every month. If your RAA of bromide is ever > 0.05 mg/L,
you must return to routine (monthly) bromate monitoring. NOTE: Monitoring the source water for bromide is optional and is only
necessary if you choose to try to qualify for and remain on reduced bromate monitoring (40 CFR 141.132(b)(3)(ii).
WHERE DO I TAKE THE SAMPLES?
You must take your routine or reduced bromate samples at the EPTDS (see Table 7 for locations) (40 CFR 141.132(b)(3)(i)). If you
choose to sample for bromide to obtain reduced monitoring status, you must sample your source water (40 CFR 141.132(b)(3)(ii)).

HOW DO I DETERMINE COMPLIANCE?
Compliance with the bromate monitoring requirements is determined by an RAA of your monthly samples (or monthly averages if you
take more than one sample per month), calculated at the end of each quarter. If your RAA exceeds the MCL, your system is in violation.
For example, if System A's monthly results for the last 12 months were 0.015 mg/L, 0.010 mg/L, 0.010 mg/L, 0.012 mg/L, 0.014 mg/L,
0.016 mg/L, 0.010 mg/L, 0.012 mg/L, 0.010 mg/L, 0.012 mg/L, 0.015 mg/L, and 0.013 mg/L, the sum of System A's 12 monthly results
(0.149 mg/L) divided by the number of samples collected (12) equals 0.012 (> MCL). System A has committed an MCL violation.
If you are on reduced monitoring and your RAA for bromate exceeds the MCL, your system is in violation. You must notify the public and
report to the state (40 CFR 141.134) whenever you commit a violation. Table 8 presents compliance criteria and identifies MCL violations
(40 CFR 141.133(b)(2)). The next section of this guide provides information on reporting requirements.

Analysis and Reporting
Supplement A -14

Who Must Analyze My Samples?
The Stage 1 DBPR specifies analytical methods for measuring each relevant water quality parameter covered by the Rule. You must use
analytical methods specified in the Rule or otherwise approved by EPA to monitor and show compliance under the Stage 1 DBPR. For
more information on analytical methods, see 40 CFR 141.131 or refer to the Stage 1 Disinfectants and Disinfection Byproducts Rule:
Laboratory Quick Reference Guide (EPA 16-F-02-021), available online at
www.epa.gov/safewater/publicoutreach/quickreferenceguides.html.
Monthly chlorite sample analysis must be done by a certified laboratory. Your system operator, however, may be able to qualify for state
approval to analyze chlorine dioxide and daily chlorite samples. Bromate sample analysis must be done by a certified laboratory. If you
choose to sample for bromide to attempt to qualify for reduced bromate monitoring, your system operator may be able to qualify for state
approval to collect and analyze bromide samples. Contact your state for more information. Contact information is provided in Appendix
E. Tribal contact information is provided in Appendix F.
Supplement A -15
-------
What Do I Report to the State?
All public water systems (PWSs) required to comply with the Stage 1 DBPR must report routine sampling results to their state within 10
days of the end of each quarter in which they collect samples (40 CFR 141.134(a)). Table 9 shows what information must be included in
your chlorine dioxide and chlorite routine report. Table 10 shows what information must be included in your bromate routine report. You
must also report all MCL, MRDL, and monitoring violations. You must notify the state within 48 hours of a non-acute chlorine dioxide
MRDL violation, a bromate MCL violation, or a chlorite MCL violation. Due to the acute health effects of chlorine dioxide, you must report
acute chlorine dioxide violations to your state as soon as possible, but within 24 hours (40 CFR 141.202(b)(2)).

What Do I Report to My Customers?
Letting your customers know what is happening with their water system is part of your legal responsibility. In addition, informed
customers are more likely to understand the need for new treatment systems, infrastructure changes, and rate increases. While you
should try to communicate with your customers on a regular basis, you must provide public notification (PN) in the following situations:
Remember!
You must send your state copies
of all PNs sent to your
customers for Stage 1 DBPR
monitoring, MCL, and MRDL
violations. The copies must be
sent with a letter stating that you
have met all the requirements of
the Public Notification Rule.
This must be done within 10
days of sending out a PN.
PUBLIC NOTIFICATION IN THE CASE OF A VIOLATION
The method and timing of your PN report varies based on the type of violation. If you have a
non-acute chlorine dioxide MRDL violation, a bromate MCL violation, or a chlorite MCL
violation, you must provide Tier 2 PN: that is, you must notify the public as soon as
practicable, but no later than 30 days after you learn of the violation (40 CFR 141.203(b)(1)).
Within 10 days of notifying your customers, you must also submit to the state both a
certification that you have fully complied with the PN regulations and a copy of the PN.
Unless otherwise directed by your state, you must provide notice to each customer receiving
a bill, to other service connections to which your system delivers water, and to other people
regularly served by your system who would not otherwise receive notice (e.g., house renters,
students, nursing home patients, prison inmates). You must use at least one of a variety of
PN methods. You can deliver the notice door-to-door or send it via mail. If you operate a non-community water system, you can also
post the notice in a public place. If any of your customers will not receive the notice through mail, door-to-door delivery, or postings, you
must also use other methods, like a newspaper or radio announcement, to reach these customers (40 CFR 141.203(c)).
Due to the acute health effects caused by chlorine dioxide, the requirements for an acute violation are more stringent. In the case of an
acute chlorine dioxide MRDL or monitoring violation, you must provide Tier 1 PN: that is, you must notify the public as soon as possible,
but within 24 hours using television, radio, posted notices, or hand delivery. Whatever method you choose to use must be designed to
reach residential, transient, and non-transient users (40 CFR 141.202(c)). Your state may establish other or additional methods to help
ensure that your notice reaches all users. Within 10 days of notifying your customers, you must also submit to the state both a
certification that you have fully complied with the PN regulations and a copy of the PN.
All monitoring violations (e.g., failure to take the required number of samples) must be reported to the state and to your customers.
Supplement A -17
-------
Generally, monitoring violations require Tier 3 PN, that is, you must notify your customers within 12 months of the violation. You may
include the notification in your Consumer Confidence Report (CCR) if it is published in time to satisfy the 12-month deadline. Chlorine
dioxide monitoring violations require you to issue a Tier 1 PN and notify the public as soon as possible, but within 24 hours (40 CFR
141.202(c)). Your state has the discretion to impose more stringent PN requirements. Check with your state for more information.
All PNs must include the following specific health effects language (40 CFR Subpart Q, Appendix B):
Acute chlorine dioxide: "Some infants and young children who drink water containing chlorine dioxide in excess of the MRDL
could experience nervous system effects. Similar effects may occur in fetuses of pregnant women who drink water containing
chlorine dioxide in excess of the MRDL. Some people may experience anemia.
The chlorine dioxide violations reported today include exceedances of the EPA standard within the distribution system which
delivers water to consumers. Violations of the chlorine dioxide standard within the distribution system may harm human health
based on short-term exposures. Certain groups, including fetuses, infants, and young children, may be especially susceptible to
nervous system effects from excessive chlorine dioxide exposure."
Non-acute chlorine dioxide: "Some infants and young children who drink water containing chlorine dioxide in excess of the
MRDL could experience nervous system effects. Similar effects may occur in fetuses of pregnant women who drink water
containing chlorine dioxide in excess of the MRDL. Some people may experience anemia.
The chlorine dioxide violations reported today are the result of exceedances at the treatment facility only, not within the
distribution system which delivers water to consumers. Continued compliance with chlorine dioxide levels within the distribution
system minimizes the potential risk of these violations to consumers."
Chlorite: "Some infants and young children who drink water containing chlorite in excess of the MCL could experience nervous
system effects. Similar effects may occur in fetuses of pregnant women who drink water containing chlorite in excess of the
MCL. Some people may experience anemia."
Bromate: "Some people who drink water containing bromate in excess of the MCL over many years may have an increased risk
of getting cancer."

ROUTINE CONSUMER CONFIDENCE REPORTS
By July 1 of every year, you must make a CCR available to your customers (40 CFR 141.152(b)). This report is designed to provide a
"snapshot" of the quality of the water supplied by your system over the past year. In your CCR, you must tell your customers about any
violations, the actions you took to fix the violations, and any potential health effects resulting from the violations. You can find more
information on CCRs on EPA's CCR Web site, www.epa.gov/safewater/drinkingwaterquality/index.html.

Example #1: A Small Surface Water CWS Monitors for Chlorite (Daily)
This example shows how a small surface water system using chlorine dioxide would conduct routine monitoring for chlorite and calculate compliance on a
daily basis. Although it will not be discussed in this example, the system must also monitor and calculate compliance with the chlorine dioxide MRDL.
This surface water system serves 700 persons and is required to perform daily chlorite monitoring at the EPTDS because it uses chlorine dioxide for
oxidation and disinfection. It is also required to perform monthly distribution system chlorite monitoring. Monthly monitoring for chlorite will be covered in
example #3. The system will also have to perform daily chlorine dioxide monitoring. Daily chlorine dioxide monitoring will be covered in examples #4 and
#5.
On April 18, 2005 the daily chlorite sample at the EPTDS is below the MCL. The system's daily EPTDS sample on April 17 (not shown) was also below the
MCL, so no additional monitoring in the distribution system was required. In addition, the system will not be required to take distribution system samples on
April 19, 2005.

Example #2: A Small Surface Water CWS Monitors for Chlorite (Daily)
This example shows what would happen if a routine daily entry point sample taken by the surface water system in example #1 exceeded the chlorite MCL,
but the average of the three distribution system follow-up samples did not exceed the MCL.
The system collects its routine daily entry point sample on April 19, 2005. No additional distribution system monitoring is required on April 19 because the
daily entry point sample collected on April 18, 2005 did not exceed the MCL (see example #1). The routine daily sample result collected on April 19 (1.2
mg/L) exceeds the MCL (1.0 mg/L). The system must take additional distribution system samples the next day (April 20) at each of the following three
locations: the first customer, the location of ART, and the MRT. The system must take the three sample set in addition to the routine daily entry point
sample required on April 20, 2005.
On April 20, the system takes its routine daily entry point sample (0.7 mg/L), which is below the MCL. The system will not have to take additional samples
in the distribution system on April 21, 2005. The system also takes the three additional samples required by the exceedance of the MCL at the EPTDS on
the previous day (April 19). The average of the three April 20 additional samples is below the MCL, so the system remains in compliance, even though the
sample at the first customer (1.1 mg/L) is above the MCL:

Example #4: A Surface Water CWS Monitors for Chlorine Dioxide (Non-acute Violation)
This example shows how a surface water system using chlorine dioxide collects routine daily entry point samples and commits a non-acute chlorine dioxide
MRDL violation based on consecutive daily entry point samples. Although it will not be discussed in this example, the system would also be required to
monitor and calculate compliance with the chlorite MCL.
This surface water system serves 1,000 persons and is required to perform daily chlorine dioxide monitoring at the entrance to the distribution system
because it uses chlorine dioxide as a disinfectant. On March 29, 2004 the system takes its required sample at the EPTDS. The sample (0.7 mg/L) is below
the MRDL (0.8 mg/L), and no additional monitoring is required.
On March 30, the system takes its required daily sample at the EPTDS. The sample (0.9 mg/L) exceeds the MRDL, and the system must perform
additional distribution system monitoring on March 31. Since two samples collected on consecutive days have not yet exceeded the MRDL (the routine
entry point sample for March 29 was below the MRDL), the system has not yet committed a violation.
On March 31, the system takes its required sample at the EPTDS and its three additional distribution system samples required by the March 30 entry point
sample result. Since the entry point sample (0.9 mg/L) exceeds the MRDL, the system must perform additional monitoring on April 1. Now, because two
routine daily entry point samples in a row exceed the MRDL (March 30 and 31), the system has committed a non-acute MRDL violation and must report to
the state within 48 hours and to its customers within 30 days. Because the system does not operate booster chlorination stations after the first customer,
the additional distribution system three sample set taken on March 31 (due to the MRDL exceedance on March 30) is taken as close as possible to the first
customer. The samples are taken at least 6 hours apart from one another. None of the additional distribution system samples exceed the MRDL. Based
on the entry point sample result for March 30 and the distribution system monitoring for March 31, the system has not committed an acute MRDL violation
(but does have a non-acute violation).
On April 1, the system collects its routine daily entrance point sample. The sample (0.7 mg/L) does not exceed the MRDL. No additional monitoring in the
distribution system will be required on April 2. Still on April 1, the system collects the additional distribution system samples required because of the
exceedance at the entry point on March 31. None of the additional distribution system samples exceed the MRDL. The system has not committed an
acute violation.

Example #5: A Surface Water CWS Monitors for Chlorine Dioxide (Acute Violation)
This example shows how the surface water system in example #4 commits an acute MRDL violation based on additional distribution system samples.
Although it will not be discussed in this example, the system will also be required to monitor and calculate compliance with the chlorite MCL.
On April 2, the system continues to collect its routine daily chlorine dioxide entry point sample. The sample (1.1 mg/L) exceeds the MRDL (0.8 mg/L). The
system must conduct additional distribution system monitoring the following day (April 3) to determine whether it has committed an acute MRDL
violation.
On April 3, the system collects its routine daily entry point sample. The sample (0.8 mg/L) does not exceed the MRDL (0.8 mg/L). No additional distribution
system samples are required on April 4. Still on April 3, the system conducts follow-up sampling because of the routine daily exceedance on April 2. Two
of the samples taken at the first customer in the distribution system (1.1 mg/L, 0.9 mg/L) violate the MRDL. The system has now committed an acute
violation since, in combination with the previous day's entry point exceedance, any single violation of the MRDL during follow-up distribution system
sampling constitutes an acute violation. The system must report to the state as soon as possible (but no later than 24 hours after learning of the violation)
and issue a PN within 24 hours (starting at 6 a.m., the time the first sample violated the MRDL). The system reports the violation to the state and the public
on April 3.
The routine daily entry point sample for April 4 (0.6 mg/L) does not exceed the MRDL. The system has not committed a non-acute violation. No additional
follow-up distribution system samples are required on April 5. The additional distribution system samples taken on April 4 because of the routine daily entry
point exceedance on April 3 do not exceed the MRDL. The system has not committed another acute MRDL violation on April 4.

BROMATE
Example #6: A GWUDI System Monitors for Bromate
This example discusses bromate monitoring, reporting, and compliance issues for a system using ozone.
This GWUDI system uses ozone for disinfection, so it must monitor for bromate each month. On April 18, 2005 the system takes its monthly sample at the
EPTDS. Since compliance is calculated at the end of each quarter, no further action is required. The system continues to collect one bromate sample
each month.
June 2005 marks the end of the second quarter of 2005. After collecting its sample for the month, the system must calculate its running annual average to
determine compliance using monthly results for the last 12 months. The monthly results for July of 2004 through June of 2005 are as follows: 0.012 mg/L,
0.006 mg/L, 0.009 mg/L, 0.008 mg/L, 0.009 mg/L, 0.012 mg/L, 0.009 mg/L, 0.009, 0.015 mg/L, 0.009 mg/L, 0.010 mg/L, and 0.011 mg/L. Since the system
did not collect a sample in May, it only has 11 samples available to calculate its running annual average. To determine whether the system has violated the
MCL, the system sums all available monthly samples for the last 12 months (12 samples) and divides it by the total number of samples taken (12):
0.012+0.006+0.009+0.008+0.009+0.012+0.009+0.009+0.015+0.009+0.010+0.011 mg/L
= 0.010 mg/L < MCL
12
Four of the individual monthly results in the last four quarters exceed the MCL. However, the system is in compliance because none of these results cause
the RAAto violate the MCL (0.010 mg/L). No further action is required except to report to the state on or before the 10th day after the end of the quarter.
For this example, the routine monitoring report is due on July 10, 2005. The system reports to the state on July 1, 2005, the same day it issues its CCR.

Appendix B: Sample Monitoring Worksheets
The following worksheets are designed to help you keep track of your Stage 1 DBPR sampling and results. These worksheets are designed
to allow you to record both the results from your routine monitoring and the results from additional monitoring (where applicable). While
these worksheets may be a useful management tool, system operators should also keep the original laboratory results on file.
The worksheets can help you ensure that you collect the right number of routine samples in each monitoring period and that you calculate
compliance correctly. The worksheets will also remind you of corrective actions you will have to take if you violate the MCL or MRDL.
Each worksheet includes an explanation of how to complete it and how to use it to calculate compliance. Review the examples in Appendix
A to help you understand how the worksheets would be used in real-world situations.
Note: Some states may have their own monitoring worksheets that small drinking water systems are required to complete. The
worksheets contained in this section are presented as learning tools and should not replace monitoring forms required by the
state.

chlorine dioxide samples must be taken at the EPTDS.
Step #3 Record result.
In the column labeled 'Result,' record the sample analytical result, including units of
measure.
If your result is < MRDL, no further action is required.
If your result is > MRDL, you must take 3 additional samples the next day and
complete the 'Additional Monitoring' portion of the worksheet (circle the result).
If two consecutive daily samples exceed the MRDL, you have committed a non-acute
violation. Check the box labeled 'Non-acute.' You must notify your state and your
customers.
Step #4 Monitoring report.
All systems must report to their state after each quarter in which they collected samples.
Systems that commit a violation must also report to the state. Enter the date you send
your report to the state in the column labeled 'Date Report Sent to State.' Also note the
type of report and violation and the submission date.
Systems monitoring for chlorine dioxide must submit a report within 10 days of the
end of each quarter.
Step #5A Record date, location, and result of additional samples.
If your daily sample exceeds the MRDL, you must take 3 additional distribution system
samples the following day. Record the day, month, and year you took the samples in
the column labeled 'Additional Sample and Date.' Where you take the samples depends
on what type of system you operate. Record the location of each sample in the column
labeled 'Location or Time.'
Systems not operating a booster chlorination station after the first customer must take
3 samples in the distribution system as close to the first customer as possible with at
least 6 hours between samples. Enter one sample on each available line (marked 1,
2, and 3).
Systems operating booster chlorination stations after the first customer must take one
sample at the EPTDS, one at the point of ART in the distribution system, and
one at the point of MRT in the distribution system. Enter one sample on each
available line (marked 1, 2, and 3).
In the column marked 'Result,' enter the analytical result of each additional
distribution system sample on the line corresponding to the appropriate sample
location. Circle any results above the MRDL.
Step #5B Determine compliance for additional samples.
Compare all three results to the MRDL. In the column labeled 'Violation Type:'

Appendix C: Monitoring Plan Worksheets and Examples
MONITORING PLAN REQUIREMENT
Under the Stage 1 DBPR, each regulated system must develop and follow a monitoring plan that describes specific locations and schedules for collecting
samples to fulfill monitoring requirements and the methods the system will use to calculate compliance with the MCLs, MRDLs, and treatment techniques.
If approved for monitoring as a consecutive system or if providing water to a consecutive system, the plan must reflect the entire distribution system. The
plan must have been made available to the state and to the public by January 31, 2004. Subpart H systems serving between 3,300 and 10,000 people
must have submitted the plan to the state by April 10, 2004 (40 CFR 141.132(f)). Developing a monitoring plan helps ensure that your system meets the
sampling requirements for the Stage 1 DBPR even if there are changes in your system's personnel. Consult Complying With the Stage 1 Disinfectants
and Disinfection Byproducts Rule: Basic Guide for more information on the monitoring plan requirements, including information on completing the basic
portions of a monitoring plan and additional blank worksheets. If you have not already developed a monitoring plan, you should contact your state for
assistance
In the pages that follow, you will find completed monitoring plan examples for chlorine dioxide, chlorite, and bromate you can use for reference. The
examples are followed by blank monitoring plan forms you can use to develop a monitoring plan.
Remember!
Your state may have additional monitoring plan requirements that are not covered in this worksheet. Check
with your state for more information.

Monitoring Plan Example #1: A Surface Water System Using Chlorine Dioxide to Disinfect
Mountain View, a surface water system serving 850 persons and using chlorine dioxide to disinfect, was required to develop and maintain a monitoring
plan and make it available for state inspection by January 31, 2004. The operator of the system, Carl Piper, completed a monitoring plan providing an
overview of system characteristics as well as individual monitoring plans for the disinfectant (chlorine dioxide) and disinfection byproducts (chlorite,
TTHM, and HAAS) for which it will be monitoring. Together, these plans present basic system information and describe where and when samples will be
collected and how the system will determine compliance with the MCLs and MRDL. Although this information exceeds the minimum information required
in a monitoring plan as described in 40 CFR 141.132(f), the operator is providing it to assist with long term, consistent operation and maintenance of the
system.
First, the operator enters system contact information, including the system's name, address, and PWSID number, and the operator's phone number and
email address. This information can be useful for state officials or customers who need to contact the system. Next, the operator enters the number of
customers (850) and the number of service connections (285) Mountain View serves. This information can help state officials who are unfamiliar with the
system determine the Stage 1 DBPR requirements with which the system must comply.
Next, the operator enters the system characteristics, including the type of system (CWS) and types of filtration (none) or disinfection used. He also
indicates that the system does not operate a booster chlorination station in the distribution system. All of these can determine which Stage 1 DBPR
requirements the system is required to meet and where it is required to collect its samples. Since Mountain View is a CWS using chlorine dioxide for
disinfection, it is required to monitor for chlorine dioxide, chlorite, TTHM, and HAA5.
The operator then makes note of the system's source and source type (i.e., surface water), its purpose (primary), its period of operation (year-round), and
how it is treated (with chlorine dioxide at Mountain View Water Treatment Plant). This information will give the state a better understanding of how and
when the system operates and how the system's source water characteristics affect its Stage 1 DBPR compliance requirements. This information is also
useful should Mountain View hire a new operator who is less familiar with the system.

Monitoring Plan Example #2: Mountain View's Chlorine Dioxide and Chlorite Monitoring Plans
Mountain View's monitoring plans for chlorine dioxide and chlorite serve as both sampling plans for the system operator and staffs own reference, and as
guides for the state to determine whether the system is sampling at the correct frequency and locations. Mountain View's operator determined that the
system is required by the state to include sampling site locations, sampling schedules, and a description of compliance determination methods in its
monitoring plans.
First, the operator indicates how often the chlorine dioxide and chlorite samples will be taken ('Sample Frequency') and at which sites ('Sample Location').
The system is required to take one daily sample for chlorine dioxide and one daily sample for chlorite, both at the EPTDS. The system is also required to
take three samples for chlorite consisting of one sample as close as possible to the first customer, one sample at the point of ART, and one sample at the
point of MRT.
Next, the operator notes the scheduled sample times. For daily samples, the operator will attempt to take the samples as early in the morning as possible.
The system will take its three monthly samples near the end of the month, because, should the system have to take additional distribution system samples
as a result of an exceedance of the MCL at the EPTDS, it can substitute the results of the additional distribution system samples for its three monthly
samples.
The operator also notes sampling locations and develops a sampling schedule for additional chlorine dioxide and additional chlorite monitoring should a
routine daily entrance point sample exceed the MRDL or MCL, and for reduced monthly chlorite monitoring, should the system qualify. In this example, the
EPTDS and the first customer locations are the same, since the WTP uses its own finished water for toilets, showers, and drinking fountains. Next, the
operator writes down a brief description of how the system will determine compliance with the chlorine dioxide MRDL and chlorite MCL. Lastly, the operator
fills in the date on which the monitoring plan was completed in the 'Date Last Modified' area. If at any point the operator needs to modify the monitoring
plan (e.g., because the state determines that the system must change its sampling locations, the system wants to take additional compliance samples, etc.)
he will indicate the date that changes were made as a reference for system staff and the state.

Acute Violations
If a routine daily entry point sample exceeds the MRDL and one of the required additional distribution system samples exceeds the MRDL as well, the
violation is acute.
If two consecutive routine daily samples (collected at the entrance point to the distribution system) exceed the MRDL, but none of the additional
distribution system samples exceed the MRDL, the violation is non-acute. If a routine entry point sample is missed the day after a routine entry point
sample exceeds the MRDL, it is considered a non-acute MRDL violation. If an additional sample (i.e., distribution system sample) is missed the day
after a routine entry point sample exceeds the MRDL, it is considered an acute violation.

Monitoring Plan Example #3: A Surface Water System Using Ozone to Disinfect
Blue Pines, a surface water system serving 1,725 persons and using ozone to disinfect, was required to develop and maintain a monitoring plan and make
it available for state inspection by January 31, 2004. The operator of the system, Mary Creek, completed a monitoring plan providing an overview of
system characteristics as well as individual monitoring plans for DBFs (bromate, TTHM, and HAAS), and any additional substances (bromide) for which it
will be monitoring. Together, these plans present basic system information and describe where and when samples will be collected and how the system
will determine compliance with the MCLs. Although this information exceeds the minimum information required in a monitoring plan as described in 40 CFR
141.132(f), the operator is providing it to assist with long term, consistent operation and maintenance of the system.
First, the operator enters system contact information, including the system's name, address, and PWSID number, and the operator's phone number and
email address. This information can be useful for state officials or customers who need to contact the system. Next, the operator enters the number of
customers (1,725) and the number of service connections (523) Blue Pines serves. This information can help state officials who are unfamiliar with the
system determine the Stage 1 DBPR requirements with which the system must comply.
Next, the operator enters the system characteristics, including the type of system and types of filtration (none) or disinfection used. All of these can
determine which Stage 1 DBPR requirements the system is required to meet. Blue Pines is a CWS using ozone for disinfection. Therefore, it is required to
monitor for bromate, TTHM, and HAA5.
The operator then makes note of the system's source and source type (i.e., surface water), its purpose (primary), its period of operation (year-round), and
how it is treated (with ozone at Blue Pines WTP). This will give the state a better understanding of how and when the system operates and how the
system's source water characteristics affect its Stage 1 DBPR compliance requirements. This information is also useful should Blue Pines hire a new
operator who is less familiar with the system.

Monitoring Plan Example #4: Blue Pines' Bromate Monitoring Plan
Blue Pines' monitoring plan for bromate serves as both a sampling plan for the system operator and staffs own reference and as a guide for the state to
determine whether the system is sampling at the correct frequency and in the correct locations. Blue Pines' operator has determined that the system is
required by the state to include sampling site locations, sampling schedules, and a description of compliance determination methods in its monitoring plans.
First, the operator indicates where she is sampling for bromate or bromide. Next, she indicates the sites at which bromate samples will be taken ('Sample
Location'). The system is required to take one monthly sample for bromate at the EPTDS (in this case, the water treatment plant). The system will also be
taking one monthly sample for bromide (at the source water) to attempt to qualify for reduced bromate monitoring.
The operator then notes the frequency of sampling and the number of samples that will be taken. Next, the operator notes the scheduled sample dates.
Whenever possible, the operator selects dates early in the sampling period to allow for time to address any compliance problems or lab capacity issues.
The operator also notes sampling locations and develops a sampling schedule for reduced bromate monitoring should the system qualify.
Next, the operator writes down a brief description of how the system will determine compliance with the bromate MCL.
Lastly, the operator fills in the date on which the monitoring plan was completed in the 'Date Last Modified' area. If at any point the operator needs to
modify the monitoring plan (e.g., because the state determines that the system must change its sampling locations, the system wants to take additional
compliance samples, etc.) she will indicate the date that changes were made as a reference for system staff and the state.

Compliance Determination
When on a routine monitoring schedule, Blue Pines will sample monthly for bromate and monthly for bromide. At the end of every quarter, Blue Acres
will sum the monthly bromate results taken in the last 12 months and divide the result by the number of months in which samples were collected. If the
result is greater than the MCL, the system has committed a violation.
When on a reduced monitoring schedule, Blue Pines will calculate the RAA at the end of every quarter using the quarterly results from the most recent 4
quarters. If the result is greater than the MCL, the system has committed a violation.
Blue Pines will calculate the bromide RAA to determine eligibility for reduced monitoring for bromate using the same method. At the end of every
quarter, Blue Pines will sum the monthly bromide results taken in the last 12 months and divide the result by the number of months in which samples
were collected. If the result is lower than the level required to qual fy for reduced monitoring status, Blue Pines will contact the state to request written
permission to begin reduced monitoring for bromate.
