1.0 INTRODUCTION
A Consent Decree, with an Effective Date of April 27, 2012, was entered into between the
United States of America, the Missouri Coalition for the Environment Foundation, and the
Metropolitan St. Louis Sewer District (“MSD”) in the matter of The United States, et al. v.
The Metropolitan St. Louis Sewer District, Case No. 4:07-CV-1120-CEJ (E.D. Mo.).
MSD prepared this Semi-Annual Report in compliance with paragraph VIII.72 of the
Consent Decree. The submission date of this Semi-Annual Report is August 15, 2022 and
provides reporting data for the six-month period of January 1, 2022 to June 30, 2022.
This Semi-Annual Report includes the following:
Constructed SSO Activation Data (satisfies Consent Decree requirement VIII.72.a)
Building Backup Data (satisfies Consent Decree requirement VIII.72.b)
Sanitary Sewer Overflow Data (satisfies Consent Decree requirement VIII.72.c)
Metropolitan St. Louis Sewer District
Semi-Annual Report – January 1 to June 30, 2022

2.0 CONSTRUCTED SSO ACTIVATION DATA
Pursuant to the requirements set forth in paragraph VIII.72.a of the Consent Decree, the
Constructed SSO discharge activations that occurred during the six-month reporting period
covered in this Semi-Annual Report are listed in Appendix A.
The Constructed SSO discharge activation data for MSD’s service area is recorded in a
Telog software system. The Telog software has embedded alert formulas that are used to
validate field equipment alarms. Site inspection following field equipment alarms is part
of MSD’s validation process. Constructed SSO discharge activations determined to be
valid are identified in Table A-1. Constructed SSO discharge activations determined to be
excluded from the valid data are identified in Table A-2. Activations were excluded from
the valid data because: (1) the activations did not meet the pre-set overflow level and
voltage requirements for the Telog formula; or (2) a site inspection determined that the
activation was not valid based on certain conditions at the outfall (e.g. low battery, bad
sensor, debris stuck in the valve, etc.).
The Constructed SSO activation data included in this report detail activations of the field
equipment alarms. Please note, however, that there will be instances where there may be
more than one field equipment alarm for a single Constructed Sanitary Sewer Overflow or
discharge. This situation occurs from time to time due to intermittent or variable flow
conditions within the Sewer System. More particularly, the rubber duck bill valves open
and close depending on the amount of pressure provided by the flows within the Sewer
System.
For the Constructed SSO discharge activation data provided, MSD has included: (i) the
Constructed SSO Outfall number; (ii) address; (iii) the start date of the event; (iv) the event
duration; and (v) the estimated volume, if known. The column headings of Table A-1 and
Table A-2 in Appendix A represent the following information:
Bypass Number
The bypass number provided is designated by MSD’s Constructed SSO Outfall
Inventory.
Address, Zip Code
The address and zip code of the site provided is designated by MSD’s Constructed
SSO Outfall Inventory.
Event Start Date, Event End Date
These are the date/timestamps representing the start and stop time recorded for this
event by the Telog software.
Metropolitan St. Louis Sewer District
Semi-Annual Report – January 1 to June 30, 2022

Event Duration (day hh:mm:ss)
This is the information recorded by the Telog software and represents the duration
time of the event. The Telog software measures this time in two and one half
minute increments.
Estimated Volume (gallons)
The estimated volume is reported as “unknown” for the majority of valid
activations that occurred during this reporting period. Most of the existing
monitoring equipment only measures water level, not velocity, which makes any
flow volume calculation inaccurate and highly unreliable. All new and replacement
flow monitors installed after April 27, 2012 include the capability to measure level
and velocity so that a flow rate and subsequent volume may be calculated.
Between March 5, 2022 and May 1, 2022, six (6) Constructed SSO locations (BP-016 at
14 Oakleigh, BP-024 at 2338 Goodale, BP-416 at 9431 Bonhomme Woods, BP-433 at 26
Hill-N-Dale, BP-583 at 842 Louwen, and BP-618 at 9058 Rosemary Ave) experienced
equipment malfunctions resulting in a loss of data. During this time period wet weather
events had occurred.
MSD provides estimated discharge volume when both level and velocity outputs indicate
predictable flow duration curve response during a valid event. Although estimated
discharge volumes can be calculated, the quality of the data is questionable due to the less
than ideal pipe characteristics for placing the flow meter. More particularly and according
to the manufacturer’s recommendations for installation, the flow meter provides the best
results in flow streams with uniform flow (not intermittent or variable flow conditions).
The manufacturer of the flow meter advises that poor channel conditions may cause
incorrect or erratic readings. Areas to avoid pursuant to the manufacturer are:
Outfalls or channel intersections
Flow streams at very low levels with high flow rates
Turbulence
Channel sections that are apt to collect debris or silt
Depths that consistently run below 1 inch
All of the flow meter installations are in areas exhibiting most, if not all, of these poor
channel conditions. As a result, the reported estimated volumes are likely inaccurate. As
of June 30, 2022, MSD has installed twenty-three (23) flow monitors with the capability
to measure level and velocity.
In some instances, the flow data was found to be completely unacceptable and therefore,
was not used for estimating discharge volume. An example of this would be when the
meter records negative or zero-value velocities due to backflow or turbulent conditions.
Another example would be when the meter records erratic level values due to a faulty
sensor. MSD, however, makes good faith and reasonable efforts to obtain accurate volume
data whenever possible.

Semi-Annual Report – January 1 to June 30, 2022

Pursuant to subparagraph V.C.15.e of the Consent Decree and in the event MSD cannot
obtain accurate velocity data within six months of installation, the equipment can revert to
the level-only monitoring setup. Although MSD identified flow meter installations
meeting this condition more than a year ago (i.e., MSD was unable to obtain accurate
velocity data), MSD elected to leave all flow monitors installed to date in service. MSD
has historically gone above and beyond Consent Decree obligations regarding the
maintenance of the flow meters at these Constructed SSO locations. Due to the concern
over flow meter data quality, MSD has maintained two separate systems at the Constructed
SSO locations (flow meters and level-only sensors with rubber duck bill valve sensors).
However, as the number of area velocity meter locations increase and the amount of
accurate velocity data decreases, MSD believes that it is prudent to reduce the time and
effort spent on maintaining two separate systems. Moving forward, MSD will invoke
subparagraph V.C.15.e of the Consent Decree by actively removing the flow meters in
locations that do not provide accurate velocity data within six months of installation. Based
on our most recent evaluation, MSD has identified a number of flow meter installations
that cannot obtain accurate velocity data and will be removed pursuant to the Consent
Decree.
MSD did not remove any flow meters during this reporting period, January 1, 2022 through
June 30, 2022 as a result of inaccurate velocity data.

3.0 BUILDING BACKUP DATA
Pursuant to Consent Decree requirement VIII.72.b, Building Backups that occurred during
the six-month period covered in this Semi-Annual Report are listed in Appendix B.
The Building Backup data included in Table B-1 was generated from MSD’s computerized
maintenance management system. Due to certain limitations with MSD’s computerized
maintenance management system, however, a Building Backup in a multi-unit building
with different numerical street addresses for each unit within the same building (e.g., an
apartment building) are reported as separate occurrences. MSD reports these Building
Backups as separate occurrences even though the Building Backup occurred in a single
building at the same time. During this reporting period, there were also Building Backups
which resulted from water main breaks. Those Building Backups are not included in this
report because an investigation by MSD led to the conclusion that these backups were the
result of private property defects and did not result from blockages, flow conditions or
malfunctions within the Sewer System. Additionally, this data includes occurrences that
were the result of the failure of a sewer separation device within a private lateral. Although
these backups are the result of a failed sewer separation device, they are reported as
Building Backups when caused by blockages, flow conditions, or malfunctions within the
Sewer System.
Ongoing investigations may result in the cause or causes of certain Building Backups to be
reclassified (i.e. blocked main, sewer separation failure, overcharged main, pump station
failure, etc.). These changes will not be addressed in the narrative, however may be
apparent in future reports should reoccurring Building Backups happen at a given address.
When Building Backups occur in the last weeks of a reporting period, they are sometimes
not resolved in sufficient time to be included in their respective Semi-Annual Report.
Customers have 30 days to report a possible backup and MSD has 30 days to evaluate the
backup claim. This total of 60 days exceeds the reporting deadline for Semi-Annual
Reports that are due 45 days after the reporting period. MSD identified two (2) Building
Backups that occurred during the July 1, 2021 to December 31, 2021 reporting period that
were not included in the February 15, 2022 Semi-Annual Report. These two (2) Building
Backups are included in Table B-1 of this report and are identified with an asterisk.
For the Building Backup data provided, MSD has included: (i) street address at which the
Building Backup occurred; (ii) identification of the Watershed/Treatment Plant Service
Area in which the Building Backup occurred; (iii) cause or causes of the Building Backup,
if known; (iv) call date(s) of any Building Backup(s) that have previously occurred at the
same address since the Effective Date of April 27, 2012; and (v) an indication for those
Building Backups that have resulted in a discharge to waters of the United States
(“WOTUS”). The column headings of Table B-1 in Appendix B represent the following
information:

4.0 SANITARY SEWER OVERFLOW DATA
Pursuant to Consent Decree requirement VIII.72.c, all known Sanitary Sewer Overflows
that occurred during the six-month reporting period covered by this Semi-Annual Report
are listed in Appendix C.
The known Sanitary Sewer Overflow data (other than Constructed SSO activations and
Building Backups) is included in Table C-1 and was generated from MSD’s computerized
maintenance management system. Per the Consent Decree definition of Sanitary Sewer
Overflow, the data only includes overflows, spills, diversions and releases of wastewater
from or caused by MSD’s sanitary sewer system. The data does not include overflows for
MSD’s combined sewer system. Copies of all unpermitted CSO discharge reports
submitted to MDNR will be provided with the Consent Decree Annual Report.
MSD, on occasion, receives initial notification of a Sanitary Sewer Overflow occurrence
reported by an MSD customer or by a third party. MSD responds as expeditiously as
possible, normally within four (4) hours. Instances with extended response times are
typically due to the Sanitary Sewer Overflow being first identified as a different problem,
such as an odor complaint from a customer.
For the Sanitary Sewer Overflow data provided, MSD has included: (i)
Watershed/Treatment Plant Service Area where the Sanitary Sewer Overflow occurred; (ii)
location description; (iii) facility type; (iv) volume, if known; (v) reason such as blockage,
broken pipe, weather conditions, power outage, vandalism, third-party cause, Mississippi
River backflow; (vi) cause such as debris, grit, grease, high river flow; (vii) the amount of
time to commence investigation of each SSO, as reported; and (viii) the amount of time to
correct and/or cleanup each SSO, as necessary. The column headings of Table C-1 in
Appendix C represent the following information:
Work Order Start Date
This is the date of the initial notification to MSD’s Division of Environmental
Compliance (“DEC”) after an MSD Operations Crew has arrived onsite and
determined that an SSO occurred. DEC records information related to the overflow
using a work order in MSD’s computerized maintenance management system.
Watershed/Treatment Plant Service Area
The watershed indicated is a wastewater collection area upstream of one (1) of the
seven (7) MSD wastewater treatment plants.
Service Address
This is the work order service address location information that has been recorded
in MSD’s computerized maintenance management system. This information
represents the best address that a MSD Staff member who responded on site
Metropolitan St. Louis Sewer District
Semi-Annual Report – January 1 to June 30, 2022
11
determined relates to the overflow. The service address includes a street number,
street name and zip code.
Location Description
The location description listed is an MSD collection system structure such as a
manhole, gravity main or pump station. These MSD collection system structures
denote respective GIS coordinates, when available.
Facility Type
The facility type indicates the type of MSD collection system structure determined
to be source of the Sanitary Sewer Overflow.
Estimated Volume (gallons)
The estimated volume of the Sanitary Sewer Overflow is indicated in gallons, if
known. The estimated volume provided is determined to the best of MSD’s ability,
which accounts for the period of time MSD knew about the overflow and the
estimated dry weather flow for the sewer from which the Sanitary Sewer Overflow
is released. Other factors are used to make this estimation when appropriate.
Reason/Cause
The reason and the cause for the Sanitary Sewer Overflow are indicated in this
combined field under a single column heading.
Time To Commence Investigation (day hh:mm)
This is the duration of time starting at the initial notification of an SSO up until an
MSD Operations Crew has arrived on site to investigate the problem. If the time
to commence the investigation is zero that is due to the fact that the Sanitary Sewer
Overflow was discovered by an MSD crew or staff member.
Time To Correct and/or Cleanup (day hh:mm)
This is duration of time starting from when the MSD Operations Crew arrives on
site to correct the problem and/or cleanup (as necessary) until the time the Sanitary
Sewer Overflow as defined by the Consent Decree has ceased and/or the cleanup
effort is completed whichever is later.
During this current reporting period there were eight sanitary sewer failure events that
resulted in the release of wastewater at multiple locations. Although each event was
attributable to a single sanitary sewer failure, MSD has separately listed each of the
multiple locations having a wastewater release. During the period of January 1, 2022 to
June 30, 2022, a total of seventy-two (72) events caused overflows at one hundred-thirty-
one (131) locations. The details of these events that overflowed at more than one location
are described as follows:
Metropolitan St. Louis Sewer District
Semi-Annual Report – January 1 to June 30, 2022
12
On January 10, 2022, a force main and gravity sewers in the Lemay
Treatment Plant service area overflowed due to a private contractor that
broke the force main. The corrective action to repair the broken force
main required taking pump stations off line, which caused the overflows
from the gravity sewers to occur. The broken force main and the pump
stations taken off line resulted in overflows being released from two (2)
locations (GIS-1607929 and E40336). Two (2) entries on Table C-1 are
related to this one (1) event.
On February 7, 2022, MSD responded to a vent pipe overflow in the Lemay
Treatment Plant service area due to a broken gravity sewer main. The
corrective action to repair the broken main required a diversionary pumping
operation around the broken pipe, and daily vactoring out of the vent pipe.
A discharge from the vent pipe and the pipe repair site resulted in sewage
being released from two (2) locations: (GIS-2405075 and GIS-1556396).
Two (2) entries on Table C-1 are related to this one (1) event.
On February 7, 2022 thru February 9, 2022, a force main and gravity sewers
in the Missouri River Treatment Plant service area overflowed due to a
break that occurred in the force main. The corrective action to repair the
broken force main required taking pump stations off line, which caused the
overflows from the gravity sewers to occur. The broken force main and the
pump stations being taken off line resulted in sewage being released from
eighteen (18) locations (E73450, GIS-1641116, GIS-10379496, GIS-
1544347, GIS-1544348, GIS-1544346, GIS-1544129, GIS-1544128, GIS-
