Importance: High
Attached is a draft violation notice to the City of Flint regarding the exceedance of the drinking water standard
for total trihalomethanes (TTHM) based on the latest round of samples collected in February 2015.
As predicted, the levels from the latest round are all very low, but the annual average calculation for 2 sites
remains above the maximum contaminant level standard.
We plan to get the letter out on Thursday so please provide any by Wednesday
3/4. An electronic copy of the signed letter will be provided to Maggie/Sarah for forwarding to legislative
members in the Flint area as was done with the last violation notice from December.
Again, if you have any questions, please contact me directly.

Dear Mr. Wright:
SUBJECT: Violation Notice - Maximum Contaminant Level for Total Trinalomethanes
Operational Evaluation — Total Trihalomethanes
1*' Quarter 2015 Monitoring Period
The Department of Environmental Quality (DEQ), Office of Drinking Water and
Municipal Assistance (ODWMA), records show that the City of Flint is in violation of the
Safe Drinking Water Act,1976 PA 399, as amended (Act 399); R 325.10610, Maximum
contaminant levels (MCL) for disinfection byproducts, of the 1979 Administrative Code.
In accordance with R.325.10610, MCLs for disinfection byproducts, of the 1979
Administrative Code, the MCL for disinfection byproduct total trihalomethanes (TTHM) is
0.080 milligrams per liter (mg/L) as a Locational Running Annual Average (LRAA) at
each monitoring location. As listed in the table below, our records show that the City of
Flint’s hignest TTHM locational running annual average (LRAA), based on the last four
quarters, ending February 28, 2015, is 0.105 mg/l which exceeds the standard, and that
two of the eight sample site locations exceed the standard of 0.080 mg/L.
Further, in accordance with R325.10719l, Disinfection byproducts: operational
evaluation levels, of the 1979 Administrative Code, when an operational evaluation level
(OEL) at a monitoring location for TTHM exceeds 0.080 mg/L, a supply shall conduct an
operational evaluation and submit a written report of the evaluation to the department
not later than 90 days after being notified of the analytical result that causes the supply
to exceed the operational evaluation level. As listed in the table below, our records
show that TTHM operational evaluation levels for the City of Flint exceed 0.080 mg/L at
one of the City’s eight sample site locations.

Our investigation consisted of a review of ODWMA files for laboratory reports received
for compliance monitoring. Our investigation is considered complete. This violation
began on March 1, 2015, and will continue until TTHM LRAA is below the MCL at all
sample sites.
We are encouraged by the results from the most recent round of compliance samples
collected on February 17, 2015, which now show individual TTHM levels at less than
half of the 0.080 mg/L standard at all locations throughout the City’s system.
Operational Evaluation Reports from December 2014 and February 2015 have
identified possible causes and corrective measures for the previous elevated TTHM
levels which we encourage the City continue implementing. These modifications have
likely contributed in part to the reduction in TTHM levels reported in the most recent
quarter, and suggest the City may be able to achieve compliance with the TTHM
standard at all sites by continuing these efforts.
Our office is currently reviewing the Operational Evaluation report dated February 27,
2015, and will provide the City and their consultant comments as needed to help
address this MCL violation.
Water systems that exceed the OEL must complete and submit an Operational
Evaluation in accordance with Administrative Rule 7191 (R325.107191) within 90 days of
being notified of the violation. An updated Operational Evaluation report, which
incorporates the most recent sample results, must now be completed and
received by our office by no later than Friday May 29, 2015.
If you have any other factual information you would like us to consider regarding the
violation identified in this Violation Notice (VN), please provide them in a written
response by March 19, 2015.
Administrative rule R 325.10403 of Act 399 requires that suppliers provide public notice
(PN) as soon as practical, but no later than thirty (30) days after the supplier learns of
this type of violation, by mail or direct delivery and by any other means reasonably
xxxEND_PAGE:deq20_b01_001_057_48
calculated to reach customers not normally reached by mail. Enclosed is a sample PN
which contains the minimum required language. The City is encouraged to include
additional information regarding its response efforts to this violation. Please notify
your consumers by April 1, 2015, and send us a signed and dated copy of the
notice that you issued within ten (10) days of distributing the public notice. This
violation must also be included in your 2015 Consumer Confidence Report (CCR), due
by July 1, 2016. The PN must be repeated every quarter until you no longer exceed the
TTHM standard. Failure to issue a PN for this violation will result in a fine of at least
$1,000 per event, with a maximum of $5,000 per violation.
We anticipate and appreciate your continued cooperation in resolving this matter. If you
have any questions regarding this VN, please contact us at the numbers below.

IMPORTANT INFORMATION ABOUT YOUR DRINKING WATER
City of Flint Did Not Meet Treatment Requirements
Our water system recently violated a drinking water standard. Although this incident was not an
emergency, as our customers, you have a right to know what happened and what we are doing to correct
this situation.
We routinely monitor for the presence of drinking water contaminants. Samples were collected for total
trinalomethanes (TTHM) analysis from eight locations on a quarterly basis (May 21, August 21,
November 20 of 2014 and February 17, 2015). The average of the results at ANY of the eight locations
must not exceed the maximum contaminant level (MCL) for TTHMs, otherwise our water system exceeds
the Maximum Contaminant Level (MCL). The standard for TTHMs is 80 ug/L. The location reporting the
highest TTHM level was 105 ug/L; thus, our water system exceeds the TTHM MCL.
What should | do?
e There is nothing you need to do unless you have a severely compromised immune system, have
an infant, or are elderly. These people may be at increased risk and should seek advice about
drinking water from their health care providers.
e You do not need to boil your water or take other corrective actions. If a situation arises where the
water is no longer safe to drink, you will be notified within 24 hours.
What does this mean?
This is not an emergency. If it had been an emergency, you would have been notified within 24 hours.
People who drink water containing trihalomethanes in excess of the MCL over many years may
experience problems with their liver, kidneys, or central nervous system, and may have an increased risk
of getting cancer.
What is being done?
We are currently working on solutions to correct the problem. We anticipate resolving the problem in
2015. Our most recent individual sample results were all less than half the 80 yo/L_ standard, however
since compliance is calculated using a locational running annual average (LRAA) of the most recent 4
quarters, we are still out of compliance with the MCL at 2 of 8 locations.
For more information, please contact Mr. Brent Wright at 517-787-6537 or the Flint Water Plant at
4500 North Dort Highway, Flint, MI 48505.
Please share this information with all the other people who drink this water, especially those who may not
have received this notice directly (for example, people in apartments, nursing homes, schools, and
businesses). You can do this by posting this notice in a public place or distributing copies by hand or mail.
This notice is being sent to you by the City of Flint.
CERTIFICATION: WSSN: 02310
| certify that this water supply has fully complied with the public notification requirements
in the Michigan Safe Drinking Water Act, 1976 PA 399, as amended, and the
administrative rules.
