Additional MCM 2 Activities: MSD continued to organize with partner organizations an
annual Plan Area stream clean-up event. Each co-permittee will participate with the
planned event, or participate in their own clean-up activity in the community. With success
and commitment from partners, the event will become an annual event.
Responsibility: Co-permittees
Status: Appendix G contains a summary of the co-permittees’ response to this goal.
Forty-five (45) co-permittees reported participating in a Plan Area clean-up event,
providing labor, equipment, disposal tools, and/or marketing activity.
MSD, with input from the St. Louis municipality stakeholders, is addressing this goal
through the organization of three major annual clean-up areas within the District. MSD
partners with an existing, major clean-up effort currently in place in each area and
organizes the participation of the co-permittees within the area during the clean-up. Three
major clean-ups were chosen as follows: Operation Clean Stream in the Meramec
watershed organized by the Open Space Council, River des Peres Watershed Trash Bash
organized by the River des Peres Watershed Coalition, and the Confluence Trash Bash in
the Missouri and northern Mississippi watersheds organized by various partners. During
the reporting period, Operation Clean Stream and the River des Peres Watershed Trash
Bash resulted in the collection and proper management of 14 tons of trash, 3.7 tons of
recycled metal and plastic bottles, and 275 tires. The Confluence Trash Bash took place
on March 19, 2016 and the results not included in this report period.

MCM 3 – Illicit Discharge Detection and Elimination
Annual Plan Goal: Reach at least 20% of MSD’s industrial customers each year with an
illicit storm water discharges brochure as measured by number of brochures produced
and distributed.
Responsibility: MSD
Status: MSD’s Division of Environmental Compliance Industrial Pretreatment Program,
through their facility inspections, distributed illicit storm water discharges brochures to 404
industrial customers explaining the best management practices for facility maintenance,
fleet maintenance, waste management and spill prevention. The distribution of brochures
to this target group represented 37% of our total industrial users. Note that the MSD
pretreatment program schedules inspections of industrial users on an annual, two-year or
four-year schedule depending on the industry’s regulatory classification.
Annual Plan Goal: Illicit discharge detection surveys of all area streams will continue
with 1,400 miles of open channel inspection reported during the permit term, averaging
280 miles of streams surveyed per year over 5 years. MSD will report stream miles
inspected, the findings of the inspection, and the actions taken.
Status: During the reporting period, the channel inspection team surveyed 146 miles of
stream looking for illicit discharges, waste disposal problems, and infrastructure
maintenance needs.
Sixteen (16) potentially illicit discharges were recorded in the MSD geographic information
system (GIS) database. Nine (9) of those findings were investigated and confirmed to be
illicit discharges, including:
• One (1) broken water line that was repaired by the City of Kirkwood.
• Two (2) discharges related to land disturbance sites that were resolved by the
jurisdictional municipality in one case, and the property owner in another.
• Two (2) discharges of sediment from non-construction sites that were resolved a
property owner and jurisdictional municipality.
Page 10
• Three (3) discharges from failing residential sewer systems. All discharges were
eliminated by the home owners with cost share assistance provided by the City of
Kirkwood’s lateral repair program.
• One (1) non-dechlorinated residential pool discharge that was resolved by the owner.
Seven (7) of the 16 findings were investigated and ultimately classified as permissible
discharges.
Fifty-six (56) waste findings resulting from improper disposal of yard waste (55 findings)
and trash (1 finding) were identified by the stream survey team. In response to these
observations, 61 door hangers were distributed to area residences to educate them on
proper waste disposal techniques and the impacts to streams from yard waste and trash.
While no animal waste was found in a channel, the potential for animal waste runoff was
noted at five sites. Such sites included “hobby” farms and horse stables, and a single
backyard chicken coop. One (1) educational door hanger was delivered to the property
with the chicken coop as a result of its close proximity to the stream channel.
Two (2) blockages were observed and reported to the responsible party for clearing.
Blockages were generally observed where open channels enter the upstream end to an
enclosed storm sewer.
In addition, 103 findings not related to illicit discharges, but to infrastructure maintenance
needs were identified. Fifty-eight (58) exposed or potentially damaged structures
including, but not limited to, sanitary sewer pipes or manholes were identified and referred
to the MSD Engineering Planning Division for asset management purposes. Of these, 29
were also referred to MSD Operations Department for further investigation and/or repair in
order to prevent leaks or reduce infiltration to the sanitary system. Additional
infrastructure findings were as follows:
• Twenty-one (21) active sanitary lines constructed of ductile iron material were
recorded for information only purposes.
• Two (2) missing manhole covers were called into MSD Customer Service, and
MSD Operations Department responded in emergency status to replace them.
• Twenty-two (22) infrastructure findings were unrelated to MSD’s sewer network.
Fourteen (14) of these findings were private wastewater pipes connected to MSD’s
sanitary system. Homeowners with exposed wastewater pipes constructed of
material other than ductile iron were notified of the possible risks of pipe failure and
requirements for meeting local plumbing code.
MSD’s Division of Environmental Compliance also responded to 64 complaints related to
illicit stormwater discharges. Nineteen (19) of these complaints were found to be
permissible discharges. The remaining 45 complaints were found to be related to illicit
activity and were referred to and/or remedied by the responsible party.

Annual Plan Goal: MSD will inspect outdoor waste handling areas at restaurants as part
of the interceptor/grease trap inspections, and report the number of inspections and
violations.
Responsibility: MSD
Status: MSD’s Division of Environmental Compliance, through their restaurant
inspections, inspected 1,350 facilities. The Food Service Establishment Inspection form is
the checklist for the inspection and includes an item concerning the acceptability of
outside trash and grease disposal areas. Trash dumpsters are inspected to ensure trash
is properly stored and not leaving the property. Facility contacts are notified of the
requirements and the results of their inspection. Failure to maintain these areas properly
can result in a Notice of Illegal Discharge to a stormwater system as a violation of MSD
ordinance 12559. During the reporting period, two facilities were issued written notice of
violations based on failing the stormwater section of the MSD Food Service Establishment
Inspection. MSD also distributed 1,075 grease interceptor brochures to food
establishments. MSD maintains a database of 4,429 active facilities to track periodic
inspections.
MCM 4 – Construction Site Stormwater Runoff Control
Annual Plan Goal: Municipalities and St. Louis County will report permits issued by
name and area disturbed. This information was requested by MDNR for coordination to
ensure land disturbance program compliance.
Responsibility: Municipalities and St. Louis County
Status: The listing of permits issued are found on the table titled Land Disturbance
Program Regulating Private Development – Permits Issued in each of the co-permittees
attached Reports. A total of 125 permits were issued during the reporting period.
Eighteen (18) municipalities contract with St. Louis County for permitting and code
enforcement. A summary of the reported numbers of co-permittee issued permits is
shown in Appendix H.
Annual Plan Goal: Annually report the number of formal, written notices of violation and
further enforcement actions taken, and the companies they were taken against.
Responsibility: Municipalities and St. Louis County
Status: The listing of NOVs issued is found on the table titled Land Disturbance Program
Regulating Private Development – NOVs and Enforcement Action in each of the co-
permittees attached Reports. A total reported 22 were issued. A summary of the

MCM 5 – Post-Construction Stormwater Management
Annual Plan Goal: MSD will report the number of BMPs approved/installed, and the
number of BMPs inspected to ensure proper operation and maintenance.
Responsibility: MSD
Status: Under MSD’s Rules and Regulations and Engineering Design Requirements for
Sanitary Sewer and Stormwater Drainage Facilities, new development and redevelopment
projects are required to submit for approval, a Stormwater Management Facilities (BMP)
Operation and Maintenance Design Report and Plan, including continuing resources,
procedures and schedules to be used. Since implementation of the water quality BMP
requirements in October 2006, 1,387 projects representing 4,818 BMPs have been
constructed, permitted for construction, or under review by MSD’s Planning Division. The
most frequent of the BMP categories used was bioretention representing 49% of the
BMPs, followed by permeable pavement representing 17% of the BMPs.
All stormwater drainage facilities are inspected by MSD to ensure proper installation prior
to granting construction approval.
Privately owned BMPs are maintained by property owners. MSD follows its BMP O&M
enforcement plan to ensure the owners install, operate and maintain the BMPs according
to the approved plans. The Rules and Regulations require property owners to submit an
annual report of maintenance to ensure compliance with the BMP Maintenance Plan. In a
letter dated December 16, 2016, MSD reminded 714 BMP site owners to submit their
maintenance reports.
The initial MSD BMP inspection frequency contained in the MSD Stormwater
Management Facilities (BMP) Operation and Maintenance Enforcement Response Plan is
three years. MSD initiated 20 enforcement actions resulting from 440 BMP inspections
performed on private BMPs within the MSD service area.

Annual Plan Goal: MSD will report the number of developments utilizing the conceptual
review service.
Responsibility: MSD
Status: MSD offers the development and engineering community a conceptual review
service that will evaluate a project’s sanitary and stormwater requirements early in the
design phase of the project, prior to extensive engineering by the customer, to ensure
acceptability of the conceptual design under MSD’s Rules and Regulations. MSD offers a
quick “Basic” review, and a more “Detailed” review for an additional cost for more complex
projects. Seventeen (17) conceptual reviews were performed.
2007-2008 Plan Goal: Co-permittees will implement procedures to ensure all applicable
private and public projects involving stormwater management are reviewed and approved
by MSD.
Responsibility: Municipalities and St. Louis County
Status: During the 2007-2008 Plan Year, co-permittees were instructed that procedures
must be in place and implemented to ensure that all private and public projects involving
stormwater management are reviewed and approved by MSD. This includes any project
involving stormwater management, any altering of any storm drainage channel, altering of
site drainage or flood plain, any project that connects to the storm sewer system or open
channel, and all land disturbance projects over one acre. Fifty-six (56) co-permittees have
reported completed this goal. The co-permittees’ individual status under this goal is
summarized in Appendix J.
2008-2009 Plan Goal: MSD and partners will begin distributing educational materials to
municipalities, developers and design engineers on MSD’s urban BMPs, and to promote
the use of non-structural credits and the benefits of stormwater management planning
prior to land disturbance.
Responsibility: MSD
Status: Under a 2008-2009 goal, MSD and partners developed an educational tool titled
Site Design Guidance-Tools for Incorporating Post-Construction Stormwater Quality
Protection into Concept Plans and Land Disturbance Permitting. Co-permittees were
instructed in a letter dated April 27, 2009 to implement the Site Design Guidance
document or an equivalent procedure to ensure they are in compliance with second term
permit language in section 4.2.5.1 to assess site characteristics at the beginning of the
construction design phase to ensure adequate planning for stormwater compliance to
mimic pre-construction runoff conditions on all new development and utilize water quality
strategies on all redevelopment projects to the maximum extent practicable. Fifty-four (54)
co-permittees reported that they have implemented the “Site Design Guidance” or an
equivalent procedure. See Appendix K for a summary of co-permittee responses.
However, Black Jack is known to contract with St. Louis County for land disturbance plan
review and code enforcement, and St. Louis County Highway Department has
implemented the Guidance under their SWPPP review, which is conducted for this
contract city. Therefore, the actual total is 55 co-permittees implementing a procedure.
Page 14
2008-2009 Plan Goal: Municipalities and St. Louis County will adopt and implement at
least one additional directed growth planning and zoning strategy to protect water quality,
such as green space and buffer criteria in overlay zoning and PUDs, or stream buffers
from the P&Z booklet or equivalent conservation method. Cities that have previously
implemented ordinances or procedures that require better site design, such as stream
buffers or minimum open space requirements or maximum impervious surface
requirements utilizing at least two strategies throughout their community will have satisfied
this goal.
Responsibility: Municipalities and St. Louis County
Status: See Appendix I for co-permittees listed post-construction ordinances/strategies.
Forty-nine (49) co-permittees reported at least two planning and zoning strategies to
require better site designs to protect water quality.
MCM 6 – Pollution Prevention/Good Housekeeping for Municipal Operations
Annual Plan Goal: Training in BMPs will continue as refresher seminars and workshops,
and as BMP introduction for new employees as co-permittees implement their ongoing
employee training programs. MSD will provide BMP refresher workshops for the co-
permittees. Co-permittees will report on the number of employees trained.
Responsibility: Co-permittees
Status: Forty-nine (49) co-permittees provided refresher training to their employees on
stormwater BMPs. A summary of the number of co-permittees’ employees trained is
included in Appendix L.
MSD hosted four Phase II Stormwater Refresher
workshops for municipal employees on good
housekeeping and pollution prevention in
municipal operations at the City of Maryland
Heights Government Center; Two (2) on
November 16, 2016 and two on December 6,
2016. The workshops were an hour and thirty
minutes, and provided training on stormwater
good housekeeping BMPs for municipal
operations. One-hundred-seventy-four (174)
employees representing 27 co-permittees were in
attendance. December 6, 2016 MSD Training Workshop
As reported in the 2012-2013 annual report, MSD ceased the pre- and post-tests for the
municipal stormwater pollution prevention training. The tests were given to measure
effectiveness of the training. The eleven-question test measured understanding of
pollution sources and BMPs in municipal operations. In the 2012-2013 Annual Report, an
average increase of 1% in test scores was noted on the post-test score from attendees of
the MSD refresher workshops, based on 192 tests. The average post-test score was
90%. These test results were evidence that stormwater BMP training has been effective
and that knowledge is being retained by co-permittee employees attending the training.
Page 15
MSD encouraged co-permittees to borrow a DVD package for their use when training their
employees. The stormwater pollution prevention training DVD was made available by
MSD on loan to co-permittees to review with their employees. Three (3) municipal co-
permittees provided in-house training to their employees using the DVD, reaching 70
employees.
In a letter dated December 12, 2016, MSD mailed out the MSD workshop handout
material and the DVD package availability offer to co-permittees not attending the
November and December BMP workshops.
As part of MSD’s efforts to maintain employee awareness and training, under MSD’s
Operation and Maintenance Program for Stormwater Pollution Prevention, MSD provided
277 employees classroom training on July 13, September 20, 21, 28, 29, and October 19,
20, 2016.
In addition, a total of 26 MSD staff attended webinars on stormwater management and
green infrastructure.
Annual Plan Goal: All co-permittees will inspect their facilities to ensure implementation
of best management practices and report the number of inspections annually. Inspection
findings will be incorporated into the co-permittee’s program review and employee training
program.
Responsibility: Co-permittees
Status: Thirty-three (33) co-permittees reported performing inspections. Appendix M
contains a summary of the co-permittees’ response to this goal.
