The way you label your water
samples tells EPA a lot about the
sample. It also determines whether
your sample results will be credited
to your water system, or if you end
up with a monitoring violation if the
correct sampling location is not
clearly indicated. Everyyear, around
mid-February, EPA sends out the
annual Monitoring and Reporting
Requirements ("To Do" lists), along
with a "schematic" of your water
system. The schematic is an overly
simplified, not-to-scale diagram of
your water system. Instead of
showing individual buildings and
streets as your distribution system, it
has a large pound sign or hash-tag,
that looks like this #. There is also at
least one red star and blue arrow
indicating where a sample should be
collected for Nitrate-Nitrite, other
Inorganic Compounds (lOCs),
Synthetic Organic Compounds
(SOCs), Volatile Organic Compounds
(VOCs), and Radionuclides (RADS) (if
required). In most cases, this is NOT
the sampling point for total coliform,
disinfection byproducts, lead or
copper. There is a note on the
schematic that says "Sample Points
3
(SP) shown on the schematic are
ONLY for Nitrates, RADs, lOCs,
SOCs, and VOCs. If you sample for
other contaminants, please refer to
your individual Site Sampling or
Monitoring Plans."
The following article discusses
labeling requirements onlvfortotal
coliform, nitrate-nitrite, and
triggered Ground Water Rule (TG
GWR) samples. The information is
applicable to all public water
systems (PWSs) but there is no
discussion on how to label samples
for lead, copper, disinfection
byproducts, chemicals, asbestos,
radionuclides or any other
parameters that may be required.
Nitrate/Nitrite Monitoring Location
If your system is required to sample
for nitrate-nitrite per your
Monitoring and Reporting
Requirements, the sampling point on
-------
the schematic is marked as SPxx
(i.e., SPoi or SP04) with a
description of sample point location
(i.e., storage tank). The EPA
database will only accept samples
labeled in this mannerfor nitrate-
nitrite, other lOCs, SOCs, VOCs, and
radionuclides. The SPxx designation
tells EPA that a water sample was
collected AFTER any water
treatment processes and BEFORE it
got to the first consumer and is from
the location we call "the entry point
to the distribution system". Please
note that you may have more than
one sampling point for nitrate-nitrite
due to the number of entry points to
the distribution system representing
separate sources of water. Please
use a certified lab of your choice to
analyze the samples. It isthe PWS'
responsibility to make sure that the
lab analyzing your sample(s) for
compliance is State or EPA certified
for the specific analyte and method
being requested. Make sure the
sampling point and sample point
description (the SPxx number
previously mentioned) is clearly
noted on the lab's chain of custody
or other form that is submitted with
your water sample(s). This will
ensure that the sample result is
accurately recorded in the EPA
database as a sample for
compliance. Without the correct
sample point location, your PWS will
get a nitrate-nitrite
failure to monitor (FTM)
violation.
Total Coliform
Monitoring Location
Total coliform water
sample(s) must be
abeled with a sample location name
that clearly indicates that it is in the
distribution system, preferably with
the letters "DIST" and according to
your Revised Total Coliform Rule
(RTCR) Sample Siting Plan. For
example, "men's restroom-DIST" or
"DiST 123 Main St." Total coliform
samples must be collected within the
distribution system where the water
is used (not at the storage tank or
pump house). If you write on your
sample bottle or laboratory chain of
custody form that a total coliform
sample was collected at SPxx the
sample will be rejected and you will
receive a total coliform failure to
monitor (FTM) violation.
Ground Water Rule (GWR) (Source)
Monitoring Locations
If your water source is a well or
spring, you are required to collect a
groundwater source sample at the
well or spring if your PWS has a
routine RTCR total coliform positive
(TC+) result. Samples must be
collected from all groundwater
sources that were in use during the
collection of the routine RTCR TC+
sample, and they must be analyzed
for total coliformsand E. coti. If you
have a surface water source this
requirement does not apply to your
PWS. If you purchase water from
another system this requirement
does not apply to you either.
However, you must notify the PWS
that you purchase water from, so
that they can take their source water
sample to meet the GWR sampling
requirement.
Collect the source sample(s) at the
groundwater source(s) (well or
spring) BEFORE any treatment. You
are required to have a designated
sample tap at a location that allows
testing from the water source. If
there is no sample tap on your
well(s), you may collect the source
sample from the faucet or tank inlet
closest to the well, and then install a
more appropriate sample tap at the
source. If your groundwater sources
combine before treatment, you may
take a combined source sample, but
make sure to mark the sample
location as "combined" and note the
groundwater sources facility codes
that were combined (e.g., Combined
WL01, WL02, and WL03). This
sample must be labeled as the
Triggered Monitoring Ground Water
Rule sample (or "TG GWR" for short).
You must indicate that it is a source
sample, or collected from the well or
spring so that we know it is not one
of the required RTCR repeat samples
from the distribution system.
Remember: this sample is only
required if you use groundwater for
your source water, and have a
routine total coliform positive result.

-------
What if SPxx and/or DIST and/or
TG GWR are the same location?
What if your PWS does not have a
way to collect a sample from the
source (for the TG GWR), or from the
entry point to the distribution
system (for the SPxx for
nitrate/nitrite)? Please discuss this
situation with EPA, and EPA may
designate the first tap within the
distribution system as the same
sampling location for all three water
samples, the TG GWR, the nitrate-
nitrite, and the total coliform routine
sample. If this isthe case, you will
need to rememberto label each
sample bottle differently according
to the naming conventions described
above. Even though the sample
location is the same, the EPA
database will not accept samples
that are labeled improperly.
If a nitrate-nitrite sample is labeled
as being in the distribution system
and says DIST, you will get a nitrate
FTM violation. If the water sample
from the same location is labeled as
"TG GWR", and you intended it to be
a routine total coliform sample, it
will not be accepted as such, and you
will get a monthly total coliform FTM
violation. If a total coliform sample is
labeled as being from SPxx, you will
get a total coliform FTM violation
since the database will think the
total coliform sample was collected
from the entry point to the
distribution system and not from the
distribution system itself. Although
it sounds confusing, if you print out
your Monitoring and Reporting
Requirements, and keep the form(s)
with the correct sample point
code(s) with your sample bottles,
then you can always refer to it for
the proper way to label your
samples. We also recommend
keeping your RTCR Sample Siting
Plan close by so that you remember
where to collect your sample(s) each
month and the proper sample
naming convention to write on your
sample bottles and laboratory chain
of custody.
If you do not have an agreement
with your labto send sample results
to EPA, then please send ALL lab
reports to R8DWU@EPA.GOV as
soon as you receive them from the
lab. You must include your public
water system identification number
(PWS ID# - begins with 08 or WY560
or WY568) and the contaminant that
was analyzed in the email subject
line. If you are unsure which of your
monitoring requirements you have
fulfilled already, please take a look at
your water system on Drinking
Water Watch
(https://sdwisr8.epa.aov/Region8DW
WPUB/). Simply type in your PWS
ID# to search for your water system.
Click on your PWS ID# to bring up
your water system profile. On the

REQUIRED INFORMATION FOR TOTAL COLIFORM LAB REPORTS FOR THE REVISED TOTAL COLIFORM RULE (RTCR)
The EPA Region 8 is required to maintain a considerable amount of information about each Wyoming and Region 8 Tribal
public water system (PWS), including records of tests, measurements, analyses, decisions, and considerations to
determine compliance with the national primary drinking water regulations. This is spelled out in the federal regulations at
40 CFR §142.14.
That means that if the EPA doesn't get correct and complete information from the water system or the lab on each water
sample report from the lab, we need to ask for revisions of the report. This causes additional work for the EPA, the lab and
YOU, the water system! It may even lead to a monitoring violation if we don't receive that information.
Here is a list of the required information we need in orderto process your total coliform sample resultsforthe Revised
Total Coliform Rule (RTCR):
1. Public Water System Identification Number (PWSID)
2. Date and time the total coliform sample was collected
3. Date and time the total coliform sample was received by the lab
4. Sample location (i.e., street address, building name, or room name)
5. Sample type (i.e., Routine, Repeat or Special)
6. Total coliform (TC) and E. Coli(EC) analytical method
7. Water sample analysis result
The following will explain why these elements are required.
1. The Public Water System ID Number (PWSID) is required for a few reasons:
a. PWS's may change names or owners but the PWSID stays the same. For the EPA to track the ongoing water
quality at a site we must have the PWSID on all lab reports.
b. If a PWS has an arrangement with a lab to have their lab results sent electronically to the EPA, we may not
receive the data if there is no PWSID on the chain of custody form. In this case the PWS will get a monitoring
violation when in fact the sample was collected. *Remember: It is the responsibility of the Public Water
System, not the lab, to ensure that data arrive at the EPA by the date they are due.
c. The customer name listed on the lab report is sometimes not the PWS name that we have in the EPA's
database. Instead a consultant or a parent company is listed on the form. So, without a PWSID, the EPA can't
tell which PWS collected the water sample.
2. The date and time the total coliform sample was collected informs the EPA of the correct monitoring period forthe
sample. For example: a sample collected on October 1 cannot be counted forthe September monitoring period.
3. The date and time the total coliform sample was received by the lab is also required for determining compliance
with the Revised Total Coliform Rule since the lab methods only allow 30 hours from the time the sample was collected
to the time the lab starts the analysis on the water sample. If a sample was collected on September 23 and the lab
doesn't receive the sample until September 25 then that is over 30 hours and the lab will reject the sample. The water
system is required to collect another sample before September 30 to avoid a monitoring violation.
4. The sample location (i.e., street address, building name, or room name) is required for comparison with the Sample
Siting Plan and to determine where in the distribution system a total coliform or E, coli positive sample resuit(s) may
have occurred.
5. The sample type (i.e.. Routine. Repeat, or Special) is required to determine if the required samples were collected
that may trigger an Assessment or a monitoring violation. If a Routine sample was marked Special, then it will not be
counted towards compliance and the PWS will get a monitoring violation. If a Repeat sample is marked Routine, then
the PWS will trigger an Assessment. For more information about the correct way to label your water samples for the
-------
Revised Total Coliform Rule (and the Ground Water Rule) please see https://www.epa.qov/reqion8-waterops/rtcr-and-
qwr-sample-labelinq-instructions.
6. The analytical method is the test the lab uses to analyze your water samples. There is a list of approved testing
methods that labs are required to use for total coliform samples. If a lab uses an unapproved method, the EPA will
reject the sample and the water system will get a monitoring violation. Please check with your lab to make sure they
are using an EPA approved test method.
7. The Water sample analysis result, whether positive or negative is critical to determine compliance with the
regulation. If a sample was total coliform positive but E. coli was not analyzed it can trigger further actions or even a
violation.
WATER SYSTEM RESPONSIBILITY
Ultimately, it is your responsibility to make sure you use an EPA certified lab and that the correct information is on all of
your chain of custody forms and sample bottles when they are submitted to the lab.
BE SURE TO WRITE CLEARLY AND NEATLY ON YOUR BOTTLES AND LAB FORMS!!!
Take a few minutes before you collect your sample or before you drop it off at the lab to ensure the correct boxes are
checked and your 2s don't look like 6s or Is don't look like 7s, etc. Likewise, when you receive your sample results you
should look over the lab report and make sure all 7 items described above are on the lab report.
How to Correct A Mistake in a Lab Report for the EPA
If you see a mistake or something missing from your lab report, please work with the lab to get the information corrected
and (re)sent to the EPA. In some cases, it is ok to write the correction on the lab report and then date and initial the
correction. This is okay if a PWSID is missing or the sample location is missing. However, once you receive a lab report you
cannot change the sample type from Routine to Special, especially ifthe result istotal coliform positive (TC+).
If you are revising a lab report, you must include documentation and an explanation as to what the revision was and why it
was necessary. Communication is a large component to keeping your water system in compliance!
REMEMBER: It is MUCH easier to fix a mistake BEFORE a sample is analyzed
than afteryou receive a violation!
A GUIDE TO READING YOUR REVISED TOTAL COLIFORM RULE (RTCR) LEVEL 2 ASSESSMENT
A Level 2 Assessment can be required if a water system has multiple total coliform positive (TC+) sample results or a
combination of routine and repeat TC+ and E. coli positive (EC+) sample results. A Level 2 Assessment includes an on-site
visit by a contractor (paid for by the EPA) to evaluate different components of your water system. Sometimes a second
pair of eyes can help determine what the source of contamination may be. You must make yourself available to walk
through the system with the contractor helping identify possible issues. Part of your responsibility during the Assessment
isto discuss possible due datesfor correcting any problemsthat could be allowing bacteria into the water supply. Ifthe
corrective action section of the Assessment is incomplete, the EPA may assign certain actions and due dates that you will
be responsible for completing.
At this point, you may be thinking to yourself, "This sounds an awful lot like a Sanitary Survey that we have every 3-5 years!
How is it different?"
In a nutshell, a Level 2 Assessment is RE-ACTIVE & a Sanitary Survey is PRO-ACTIVE!

Purpose
Identify and eliminate
contamination pathways that may
be the cause of the positive
bacteriological samples that
currently exist in the water supply.
Routine review of the water
system's design, operation and
maintenance to identify failures,
malfunctions or other issues that

existing failure or imminent failure
in a protective barrier (for example,
treatment, well seal or screen) that
is already in place.
A review of the entire water system
including the following elements:
water source, treatment,
distribution system, finished water
storage, pump facilities and
controls, monitoring and reporting
and data verification, system
management and operation, and
operator compliance.

-------
The Level 2 Assessment Process
After the Level 2 Assessment evaluation, the contractor sends the EPA their draft report and then the EPA determines the
final Sanitary Defects and corrective actions. The EPA finalizes the report and mails a paper copy via certified mail to the
Administrative Contact in the EPA database. A copy is also emailed to the system's Operator, Owner, Legal Entity, the
Wyoming Department of Environmental Quality (WY DEQ), the Wyoming Department of Agriculture and the Wyoming
Association of Rural Water Systems (WARWS). Some of the required corrective actions for the identified sanitary defects
may require a permit from the WY DEQ. If a permit is required, it will be noted in the Corrective Actions document.
The Level 2 Assessment Report Packet
There are potentially six parts to the Level 2 Assessment Packet:
Part 1: A cover letter with background information about the Level 2 Assessment such as the triggering sample event
and important dates.
Part 2: A table of the Sanitary Defects found during the Assessment and the required and recommended corrective
actions and due dates proposed by the water system and those required by the EPA.
Part 3: The finalized Level 2 Assessment Report that was completed with the contractor on site.
Part u\ Photos that were taken during the Level 2 Assessment to document any possible Sanitary Defects.
Part 5: A blank Sanitary Defect Correction Notice to be completed by the water system representative to document
the completed corrective actions and the dates each action was taken and indicates if photo documentation was
included. This must be submitted to the EPA as the corrective actions are completed.
Part 6 (Optional): Supplemental Documents like the Sample Siting Plan template or the Storage Tank Cleaning
Checklist.
How to Read the Level 2 Assessment Report Packet
Once you receive the Assessment packet, you should review each section. You should read through the Assessment
Report (Part 3) and look at the photos that are referenced (Part 4) for clarification of the issue. Then review the Sanitary
Defect corrective actions and due dates (Part 2) and make sure that you understand each requirement and due date. If you
cannot meet any of the due dates listed, it is your responsibility to notify the EPA in writing BEFORE the due date and
request an extension. In the written request you should identify a revised due date and a schedule of actions needed to
meet the requested due date, along with a justification for why an extension is needed. Depending on the severity of the
issue, the EPA may accept or negotiate a different due date.
FAILURE TO REQUEST AN EXTENSION OR MEET A DUE DATE WILL RESULT IN A VIOLATION.
Everyone has the same goal when a Level 2 Assessment is triggered, to ensure the water system gets back to serving
water free of bacteria! Communication with the EPA is the best way to reach that goal!!

2020 SPRING WORKSHOPS FOR TRANSIENT WATER SYSTEM OPERATORS AND OWNERS
2020 Spring Workshops for
Transient Water System Operators
and Owners (For Camps, Lodges,
Gas Stations, Restaurants, Rest
Areas and OtherTransient Non-
Community Water Systems)
Consider attending a no cost, half-
day workshop hosted by EPA Region
8 that will specifically address issues
faced by Transient System
operators. The focus of the training
will be understanding the drinking
water regulations that apply to your
water system (the Revised Total
Coliform Rule, the Nitrate Rule and
sanitary surveys) with hands-on
learning
exercises.
The
interactive
training will
include topics
such as
creating total coliform sample siting
plans, seasonal start-up activities,
following up on positive samples, on-
site assessments, and how to
prepare for a sanitary survey. We will
also make time to answer your
questions!
Do not risk your reputation or profits
by failing to monitor according to
drinking water regulations. Providing
unsafe drinking water could sicken
your customers and result in
lawsuits, penalties and more. We are
still working on dates and locations
for two workshops. We will send an
email invitation once the details are
worked out. Stay tuned! If you are an
operator at a
Non-community water system and
are interested in having EPA come to
your area please let us know by
sending an email to

AMERICA'S WATER INFRASTRUCTURE ACT:
NEW REQUIREMENTS FOR RISK ASSESSMENTS AND EMERGENCY RESPONSE PLANS
On October 23, 2018, America's Water Infrastructure Act (AWIA) was signed into law by the US Congress. AWIA Section
2013 requires community drinking water systems serving more than 3,300 people to develop or update risk assessments
and emergency response plans (ERPs). The law specifies the components that the risk assessments and ERPs must
address, and establishes deadlines by which water systems must certify to EPA that their risk assessment and ERP is
complete. Important: only the certification of completion is required to be sent to the EPA, not the documents themselves.
New certifications will be required every five years.
Certification Deadlines
10
-------
Risk and Resilience Assessment Requirements and Assistance Resources
Each community water system serving a population of greater than 3,300 persons shall assess the risks to, and resilience
of, its system. Such an assessment shall include:
1. the risk to the system from malevolent acts and natural hazards;
2. the resilience of the pipes and constructed conveyances, physical barriers, source water, water collection and
intake, pretreatment, treatment, storage and distribution facilities, electronic, computer, or other automated
systems (including the security of such systems) which are utilized by the system;
3. the monitoring practices of the system;
4. the financial infrastructure of the system;
5. the use, storage, or handling of various chemicals by the system; and
6. the operation and maintenance of the system.
The assessment may include an evaluation of capital and operational needsfor risk and resilience management forthe
system.
Emergency Response Plan Requirements
No later than six months after certifying completion of its risk and resilience assessment, each system must prepare or
revise, where necessary, an emergency response plan that incorporates the f indings of the assessment. The plan shall
include:
1. strategies and resources to improve the resilience of the system, including the physical security and cybersecurity
of the system;
2. plans and procedures that can be implemented, and identification of equipment that can be utilized, in the event
of a malevolent act or natural hazard that threatens the ability of the community water system to deliver safe
drinking water;
3. actions, procedures and equipment which can obviate or significantly lessen the impact of a malevolent act or
natural hazard on the public health and the safety and supply of drinking water provided to communities and
individuals, including the development of alternative source water options, relocation of water intakes and
construction of flood protection barriers; and
4. strategies that can be used to aid in the detection of malevolent acts or natural hazards that threaten the security
or resilience of the system.
Community water systems shall to the extent possible
coordinate with local emergency planning committees
established underthe Emergency Planning and Community
Right-To-Know Act of 1986 when preparing or revising an
assessment or emergency response plan underthe AWIA.
Further, systems must maintain a copy of the assessment
and emergency response plan for five years after certifying
the plan to the EPA.
Where to start to meet the requirements?
Visit the EPA Water Resilience Website and take a look at th
tools and resources created by EPA to meet these
requirements. These tools and resources include templates,
interactive web software tools, incident action checklists,
and many more. Please visit the website at
https://www.epa.gov/waterresilience.

-------
Work with your Wyoming Local Emergency Planning Committees (LEPCs) to see if there is information available that can
be used forthe required documents. Underthe Emergency Planning and Community Right-to-Know Act (EPCRA), LEPCs
must develop an emergency response plan, review the plan at least annually, and provide information about chemicals in
the community to residents and water systems. A list of LEPC contacts can be found at the Wyoming Office of Homeland

If you submitted a vulnerability assessment underthe Bioterrorism Preparedness and Response Act of 2002 (Bioterrorism
Act), that older document may be a useful starting point for this new effort. You can ask EPA to return your community's
2002 vulnerability assessment by sending an email to WSD-Outreach@epa.gov. Otherwise EPA will retire these older
documents by the deadline dates listed above.

LEAD AND COPPER RULE PROPOSED REVISIONS
The EPA's comment period on the proposed Lead and Copper Rule Revisions (LCRR) closes on February 13, 2020. Please
remember that there is no need to change what you are currently doing for lead and copper compliance monitoring or
corrosion control treatment. The LCRR is a proposed rule change and is not yet effective. For additional information,
please visit https://www.epa.gov/ground-water-and-drinking-water/proposed-revisions-lead-and-copper-rule.
CHANGES TO CHEMICAL SAMPLING REQUIREMENTS: INORGANIC AND SYNTHETIC ORGANIC CHEMICAL
MONITORING AND THE NEW REQUIREMENTS TO SAMPLE FOR TOTAL POLYCHLORINATED BIPHENYLS (PCBs)
Synthetic organic chemical (SOC) monitoring is conducted
by community water systems and non-transient non-
community water systems. The requirements to sample
are based on the number of persons served, and all
systems monitor every
three years.
Systems serving 3,300
persons or less collect one
sample every three years.
Systems serving more
than 3,300 persons collect
two samples every 3
years. This monitoring
schedule can create some
confusion because the two samples must be collected in
different quarters in one year. This meansthat although a
sample is collected in one quarter and the second sample
is collected in a different quarter, the two quarters should
fall within twelve months during that 3-year compliance
period.
Your community water system or non-transient non-
community water system had been granted a waiver from
EPA that did not require you to monitor for total
polychlorinated biphenyls (PCBs). That waiver expired on
December 31, 2019. You are now required to sample for
total PCBs, along with the other SOCs. Many
laboratories already analyze for PCBs as part of the SOC
suite. Please see the complete list of twenty-nine
regulated SOCs on our website at
https://www.epa.gov/region8-
waterops. and use a laboratory that is
certified for PCB analysis.

Chemical Phase II/V Rule Manager,

Composite Sampling
The EPA permits public water systems to reduce the total
number of chemical samples that must be analyzed, and
therefore potentially decrease sampling costs, by allowing
the use of sample compositing [described in the
regulations at 40 CFR 141.23(a)(4) and 40 CFR
141.24(^(14)]. Compositing meansthat water samples
from separate sampling points are combined into a single
sample by a certified laboratory, then the single sample is
analyzed ratherthan all of the separate samples.
Composite sampling is allowed for the inorganic chemicals
(lOCs), synthetic organic chemicals (SOCs), and volatile
organic chemicals (VOCs).
Samples must be composited at the laboratory. An
operator may not composite the samples in the field. The
laboratory that performs the analysis must be EPA
12
-------
certified arid meet detection limits that are less than
one-fifth of the MCLfor the methods that are used for
analyses.
The maximum number of samples that are allowed to be
composited are five samples. That means that up to five
entry points to the distribution system can be sampled
by the operator and submitted to the lab for
compositing.
If the population served is greater than 3,300 persons,
then composting is only permitted within a single system
at up to five entry points to the distribution system
following treatment. If the population served is lessthan
or equal to 3,300 persons, then compositing may be
permitted among up to five different public water
systems, but you must first contact the EPA to obtain
approval for this second approach.
If any of the chemicals are detected in the composite
sample, then additional sampling from each separate
sampling point included in the composite sample must be
conducted within 14 days. If the lab still has the original
sample taken from each sampling point used in the
composite sample and the holding times have not been
exceeded, these may be used instead of resampling. EPA
will provide guidance and will determine compliance
based on the follow-up sample results.
Public water systems should contact the laboratory to
inquire whether the laboratory can composite samples.
Not all of the SOCs can be composited because of the low
detection limits that must be met to composite drinking
water samples, in addition, some labs may charge a fee to
composite samples.
If a decision is made to composite samples and the
laboratory is able to do so, the operator must clearly
identify each of the separate sampling points on the lab's
chain of custody form. This enables the laboratory to
identify and document all of the sampling point locations
that that are to be composited on the laboratory report
that is submitted to EPA. Composite samples should be
taken earlier in the monitoring period in the event that
additional samples are required to demonstrate
compliance priorto the end of the -monitoring period.

Rule Manager, with any questions at (303) 312-6145 or

DISINFECTION BY-PRODUCT SUBMITTAL FORMS
quarterly monitoring must submit their sample results
along with a DBP Locational Running Annual Average
(LRAA) form and possibly an Operational Evaluation Level
(OEL) form.
In the past, submitting the two separate LRAA and OEL
forms has been a back and forth process to ensure
compliance with these regulations. Recently, this process
was streamlined through combining the LRAA and OEL
calculations into one single form, which is called the
Stage 2 LRAA OEL Form.
The new Stage 2 LRAA OEL Form walks the user through
the evaluation processto ensure all possible requirements
are met for their DBP submittal. If the OEL calculations
exceed 80 ppb for TTHMs or 60 ppb for HAA5S, an
Operational Evaluation Report (OER) is required. The
All Community Water Systems and Non-Transient Non-
Community Systems adding chlorine are required to
sample Disinfection Byproducts (DBPs), as Total
Trihalomethanes and 5 Haloacetic Acids (TTHMS/HAA5S).
These DBPs are formed when chlorine interacts with
organic matter present in the drinking water.
Systems sample these contaminants on either a quarterly,
annual, or triennial basis. For systems on annual or
triennial monitoring, only the sample results are required
to be submitted to the EPA. However, systems on

-------
Operational Evaluation Report is a self-assessment of the
public water system to identify operational changes
required to ensure regulatory compliance. The Stage i
LRAA OEL Form will directly inform the public water
system whether an OER self-evaluation is required.
The new Stage 2 LRAA OEL Form is available in either a
pdf or Excel version. The pdf version has the instructions
for individualsto fill out the form manually. The Excel
version has the instructions for individualsto fill outthe
form using the automatic embedded calculations.
The DBF forms can be found at
https://www.epa.gov/region8-waterops/reporting-forms-
and-instructions-reportinq-forms#dbpr2. If you want
more information or need assistance, please contact the
