2021 ANNUAL FACILITY INSPECTION REPORT
River Sweep
The typical annual DuPage County River Sweep is a county‐wide self‐coordinated stream cleanup and
restoration event. The purpose of the River Sweep is to encourage volunteers to help “sweep our rivers clean”
by picking up debris in and along the local waterways and restoring nearby land back to its natural state. Since
its inception in 1991, over 13,812 volunteers have removed approximately 285 tons of garbage from DuPage
County waterways.
This year because of the Covid‐19 pandemic and social distancing guidelines the typical River Sweep event
could not take place. May was declared as “River Sweep Month” and residents were encouraged to get out
and cleanup the waterways near them. The Conservation Foundation posted a list of forest preserves in
DuPage County that provided river access and the Forest Preserve District of DuPage County offered to haul
away the trash. Participants were asked to take photos of their cleanup and post them on their social media
pages with the location worked at and the hashtag #riversweep and tag The Conservation Foundation. Co‐
permitees promoted River Sweep Month through newsletters and social media posts.
Conservation @Home / Conservation @Work
The Conservation@Home and Conservation@Work programs promote the use of native landscaping, rain
gardens and rain barrels to homeowners, businesses, and developers in DuPage County.
Conservation@Home/Work provides a way to educate the citizens of DuPage County about stormwater and
provides them with the resources they can use to improve water quality on their properties. DuPage County
Stormwater Management sponsors the programs which are conducted by The Conservation Foundation. The
Conservation Foundation staff conducts evaluations and certifications of residential properties, school
campuses and business properties throughout the county as well as provides information and resources for
planting and maintaining certified properties and promotes the program through presentations and
partnerships.
Though in‐person meetings were limited during the reporting year due to Covid‐19, eighteen (18) homes were
certified through the Conservation@Home program. Another thirty‐seven (37) homes are in‐progress sites for
certification in the Conservation@Home program.
Rain Barrels
During the reporting year, one hundred‐eighteen (118) rain barrels were distributed throughout the County.
Large pick‐up events could not be held this year due to Covid‐19.
The rain barrel programs, education, and promotions occurred in the following DuPage County communities
during the reporting year:

B3. Stakeholder Meeting
Goal:
DCSM will host at least two regular water quality stakeholder meetings per year in each of the partnership
area's main watersheds in order to address matters pertaining to pollutant reduction on a watershed level. In
addition, input on water quality impairments will be requested from stakeholders for incorporation into
watershed planning efforts, which may cause the formation of separate stakeholder groups any given year.
Milestone:
Participate in or organize 3 watershed stakeholder meetings per year.
Status:
DuPage County staff held one watershed stakeholder meeting in 2020 before the Covid‐19 pandemic required
a stay at home order and moving to a virtual platform to adhere to social distancing guidelines. On a virtual
meeting platform, we were able to open all workshops to all members of the public in all watersheds.
Attendance at each workshop was increased in the virtual format and we plan to continue hosting virtual
workshops in the future in addition to in‐person events once public health recommendations allow.
Additionally, two public meetings were held for public comment on watershed plans and two water quality
flags were awarded during in‐person ceremonies.

B6. Program Involvement
Goal:
Develop and distribute surveys via an email list, webpage, and on social media to measure citizen views,
behaviors, and concerns pertaining to a variety of topics, including water quality, property management, and
residential pollutant control.
Milestone:
Develop and disperse 1 survey per year.
Status:
Surveys were conducted among municipalities regarding planning of a public meeting and as part of DRSCW
activities. No formal surveys were conducted to the general public during the reporting year. However, the
DuPage County Citizen Reporter App experienced an increase in reports over 2x that of the previous year.
DuPage County staff maintains the “Citizen Reporter App” which provides citizens the opportunity to
participate in the water quality program by identifying areas for water quality improvements. By using the
app, citizens can report water quality issues such as erosion, stream blockages, algae, dumping, sediment,
garbage, and other water quality issues. The Citizen Reporter App can be accessed at:

Goal:
Partner agencies provide a current storm sewer atlas to the DCSM. DCSM will collect, compile, and field verify
storm sewer maps from partner agency data to create a comprehensive storm sewer atlas of the partnership
area (the municipal limits of all participating MS4s). The partner agencies will provide the DCSM with annual
updates of the storm sewer atlas.
Milestone:
Complete the storm sewer atlas for 70% of DuPage County.
Status:
DuPage County Stormwater staff continues to work with townships, municipalities, and other county
departments to update the storm sewer atlas with current storm sewer locations. The following updates were
completed within the reporting year:

C2. Regulatory Control Program
Goal:
DCSM will revise the IDDE ordinance as needed and provide language to partner agencies.
Milestone:
Review and amend the Ordinances, as needed to reflect new information and regulations.
Status:
The Illicit Discharge Detection and Elimination (IDDE) Ordinance was approved by the DuPage County
Stormwater Management Planning Committee and County Board in May 2009. Following approval, the IDDE
Ordinance was added to the DuPage County Code as Chapter 16. Upon review of the Code during this
reporting year, staff determined that the numbering system and wording had been automatically changed to
comply with the standard Municode system when incorporated into the County Code. In January 2021, the
DuPage County Stormwater Management Committee and County Board approved an amendment to the
DuPage County IDDE Ordinance to mirror the numbering system and language used in the Code. The
provisions of the IDDE Ordinance did not change.

C3. Detection/Elimination Prioritization Plan
Goal:
Compile information pertaining to the ten‐step prioritization plan identified in the DuPage County IDDE
Program Technical Guidance.
Milestone:
Complete Salt Creek Outfall Prioritization
Status:
After completing steps 1 and 2 in the DuPage County IDDE Program Technical Guidance outfall prioritization
plan in 2016, we were scheduled to complete steps 3 and 4 in 2017. County staff adjusted the prioritization
plan goal to complete outfall prioritization for the watershed that is scheduled for monitoring that year.
Because Salt Creek watershed was scheduled for outfall monitoring in 2020, outfall prioritization was
completed for Salt Creek using the following steps:
Step 3 – Determine which of the Reach Illicit Discharge Risk Factors and Subbasin Illicit Discharge Risk Factors
are going to be used for prioritization
Step 4 – Gather data required to compute the Reach Illicit Discharge Risk Factors and Subbasin Illicit Discharge
Risk Factors
Step 5 – Compute Reach Illicit Discharge Risk Factors
Step 6 – Compute Subbasin Illicit Discharge Risk Factors
Step 7 – Compute Subbasin Illicit Discharge Risk Scores
Step 8 – Create Prioritization Scoring Map and Table
Step 9 – Perform Critical Review
Step 10 – Review Prioritization
Steps 3‐5: The reach illicit discharge risk factor we selected was the number of outfalls per stream mile (≥30).
We considered outfalls located within 20ft of the SC_Stream_Miles GIS layer to be within the stream. Number
of outfalls per stream mile (≥30) came to 0 priority outfalls.
The subbasin illicit discharge factors selected for inclusion were land use and high nutrients. 16 subbasins
contain at least 50% industrially zoned land use, which resulted in 29 priority outfalls. We included outfalls
located in areas of high nutrients, dissolved materials, or heavy metals not associated with POTWs as listed in
the “Biological and Water Quality Study of Salt Creek and Tributaries 2013‐16” by Midwest Biodiversity
Institute Center for Applied Bioassessment & Biocriteria. Those outfalls in the high nutrient areas and within
20ft of the stream were included. However, we excluded sample locations with Phosphorous exceedances
only, as Phosphorous is high throughout the watershed. This accounted for 69 new priority outfalls.
DUPAGE COUNTY NPDES PERMIT # ILR400502
32
2021 ANNUAL FACILITY INSPECTION REPORT
Historic discharge complaint locations were included as illicit discharge risks. The DuPage County Department
of Health provided discharge and septic complaints from the last 5 years. Within the Salt Creek Watershed, we
created 500 ft buffers surrounding the complaint locations and prioritized any outfalls within the buffer, which
accounted for an additional 4 priority outfalls.
Unresolved Areas of Concern within the Salt Creek watershed were included as priorities. These are outfalls
which previously received a discharge complaint, but the source was not identified, or the issue not resolved.
This provided no priority outfalls.
Steps 6‐8 were modified to score anything that met the criteria of an illicit discharge risk factor as a priority
outfall.
This prioritization process resulted in the classification of 102 priority outfalls out of a total of 1,231 MS4
outfalls in the Salt Creek Watershed.

C5. Illicit Source Removal Procedures
Goal:
Distribute educational materials pertaining to illicit discharges to DuPage County residents and businesses.
DuPage County maintains a partnership area‐wide Illicit Discharge Detections and Elimination Hotline as well
as an online Citizen Reporter Application, where the public is able to report suspect discharges in addition to
other water quality concerns, such as erosion or stream blockages. Publications and notices advertising these
resources are created, updated, and distributed.
Milestone:
Advertise or promote the IDDE Hotline or Citizen Reporter App 5 times through publications, notices, and
events.
Status:
County staff has created 22 brochures and flyers for distribution as discussed earlier in the education and
outreach section of this report. Many of these include a link to the Citizen Reporter App. These publications
are distributed at each event the County attends as an exhibitor (also discussed in education and outreach
section). These documents are available on our website at:

2021 ANNUAL FACILITY INSPECTION REPORT
C7. Visual Dry Weather Screening
Goal:
Perform the visual screening of MS4 outfalls discharging to Waters of the State during dry‐weather conditions.
Milestone:
Inspect, during dry weather, all known outfalls within the West Branch DuPage River watershed that fall within
the partnership area. Additionally, priority outfalls will be inspected.
Status:
Salt Creek was the target watershed for the 2020/21 monitoring season. 560 outfalls were visually inspected
for illicit discharges within Salt Creek. While inspecting the outfall sites, we determined several of the pipes
were not actually outfalls, but were daylighting of streams, sump pump pipes, or some other non‐MS4 use.
Therefore, of the 560 sites inspected, only 533 were determined to be actual outfalls. Additionally, all 151 East
Branch Priority Outfalls and 104 West Branch Priority Outfalls were monitored. We also monitored the outfalls
in Lemont, which added an additional 168 outfalls. DuPage County staff continued using the ESRI Arc Collector
app for outfall inspections. This allows us to track outfall inspections digitally, eliminating the need for
paperwork. Outfall inspection and testing information is entered directly into the database, which is also
linked to the outfall map. The storm sewer inventory has also been converted into the Arc Collector app. This
allows staff to view the storm sewer atlas on a tablet or smartphone, which increases efficiency in illicit
discharge tracing.
Kayaks increased outfall monitoring efficiency along the main stem of Salt Creek and the East Branch DuPage
River. Observing outfalls from the water proved much faster and safer than driving and hiking to the
riverbank. In addition, observers were able to record river conditions that are not visible when inspecting
outfalls from the shoreline.
Additional IDDE inspections conducted by Co‐Permittees:
MS4 Details
Addison
Addison staff conducted multiple inspections of the Village’s 21 primary
outfalls during this reporting period. See the attached summary for 2020
Primary Outfalls.
The Village of Addison had identified 122 outfalls, and each was visually
inspected and the conditions recorded during the reporting period. All
outfalls were normal, and records of the inspections are available for review
in our office.
There were several investigations performed over the past year related to
pollution in the storm sewer system and local streams:
DUPAGE COUNTY NPDES PERMIT # ILR400502

2021 ANNUAL FACILITY INSPECTION REPORT
On 3/3/20, Environmental Services investigated an odor complaint
coming from a storm water basin. The septic system at 19W640 Army Trail
Rd. failed and sewage has saturated the backyard. The DuPage Co. Health
Dept. has been notified and are working with the resident.
On 5/18/20, Environmental Services received a complaint from the
resident at 740 W Seventh Ave. The complaint was concerning the flooding
issues brought, allegedly, about by the resident at 19W620 Byron.
Community Development was notified, and meetings will follow to
determine a resolution to the problem.
On 6/1/20, Environmental Services received a call from the EPA
concerning a complaint against a company located at 300 W Fay. The
company was inspected, and no evidence was found of any illegal dumping.
A spill control plan, as well as waste manifests to ensure compliance, were
requested by the Village of Addison. The company was also warned that only
storm water may enter our storm sewer system. Any semi‐tractors washed
on site must have containment for the wash water. Monitoring of the issue
has continued.
On 6/13/20, Environmental Services received was notified of an oil
and grease spill at 1050 N Rohlwing Rd. The grease spill was caused by the
business at 1070 N Rohlwing Rd. IPT personnel supervised the cleanup to
ensure compliance with our storm water codes.
In July 2020, flooding issues on Addison Rd. were investigated by
Environmental Services. The area affected by flooding is directly in front of
875 Addison Rd. A missing restrictor in a storm water manhole owned by a
company just south of the Addison city limits was identified. The company at
880 N Addison Rd. has been instructed by the Village of Villa Park to re‐install
the restrictor. The other cause of the flooding is the right of way located
behind the businesses at 50 – 80 Fay. The renters of the property have paved
the area with gravel thus creating large amounts of storm water runoff that
travels to the east onto Addison Rd. causing flooding. We are working with
all parties involved to quickly stop these flooding issues.
On 9/1/20, Environmental Services was notified about a dig near 4N
242 6th St. The truck on‐site leaked hydraulic fluid onto the street. IPT
personnel covered the spill with oil absorbing materials and were able to
remove the hydraulic fluid before entering the storm system.
On 9/15/20, 1470 W Bernard Dr. was witnessed dumping their floor
washings outside. Upon further investigation, the company was also draining
their reverse osmosis water purification system outside. The company was
informed of the penalties for their illegal discharges and have since, ceased.

On 12/7/20, the resident at 4N153 Catalpa received a “cease and
desist” letter and was given 30 days discontinue discharging raw sewage into
the storm system by fixing their septic tank or providing the proper
paperwork necessary for annexation and permits to request access to Village
utilities. The resident is in the process of submitting paperwork and payment
to Community Development to annex into the Village.
On 2/10/21, a garbage truck had a hydraulic fluid leak on Church,
Natoma, May, and Army Trail. IPT personnel inspected the spill. The
contractor was contacted and informed to return to the site to properly
clean the spill. The contractor responded and completed the work.
On 2/16/21, the Addison Fire Department requested Environmental
Services at 100 W. Lake St. IPT personnel responded to a diesel spill caused
by a punctured saddle tank on the side of a truck. The driver called Maximum
Towing and Recovery for a clean‐up in the parking lot. Hazchem responded
to vacuum out the storm basins and to place booms in the storm water
manholes. IPT personnel remained on site to ensure compliance.
Finally, the Village also performed periodic grab sampling and analysis
at 21 of the 121 outfall points. A total of 61 screening samples were collected
and 462 different field analyses were performed. Parameters tested included
Metals, D.O., Temperature, Ammonia, Nitrate, Phosphate, Turbidity and pH.
A summary of the monitoring data collected is attached in Section C. There
were no high levels reported during the testing.

D1. Regulatory Control Program
Goal:
Soil erosion and sediment control regulations for DuPage County are regulated by the DuPage County
Countywide Stormwater and Flood Plain Ordinance.
Milestone:
Review and update the Ordinance as needed to ensure that sediment and erosion control provisions are up to
date and reflect the current best practices.
Status:
Article VII of the DuPage County Stormwater and Flood Plain Ordinance outlines sediment and erosion control
requirements. No revisions were made to Article VII during the reporting year. Co‐permitees within DuPage
County follow the Countywide Ordinance. Those MS4s whose boundaries fall outside the DuPage County
limits may follow County or municipal Ordinances, all of which must be as stringent as the ILR40 soil erosion
and sediment control regulations at a minimum.
DUPAGE COUNTY NPDES PERMIT # ILR400502
46
2021 ANNUAL FACILITY INSPECTION REPORT
D2. Erosion and Sediment Control BMPs
Goal:
The DuPage County Countywide Stormwater and Flood Plain Ordinance requires temporary and permanent soil
erosion and sediment control for developments over one acre to prevent the discharge of pollutants into
waterways.
Milestone:
Require sediment and erosion control on 100% of development sites over one acre.
Status:
DuPage County co‐permitees have enacted the construction site erosion control and post‐construction best
management practice regulations of the DuPage County Countywide Stormwater and Flood Plain Ordinance or
regulations at least as stringent as those in the DuPage County Ordinance. Municipalities elect to have DuPage
County review development permits on their behalf (non‐waiver community) or waive the County review and
perform these reviews in house by qualified staff (complete waiver community) or defer to the County for
certain development reviews such as those involving floodplain or wetlands (partial waiver community). The
waiver status of each co‐permittee is listed below. DuPage County reviews all site development permits in
Unincorporated DuPage County which includes the Townships. Communities whose jurisdictions extend
beyond the DuPage County limits may opt‐in entirely to the DuPage County Stormwater Ordinance, opt‐out
into the neighboring county's regulations, or enforce both county's regulations.
During the reporting year, each co‐permitee that issued development permits required soil erosion and
sediment control for sites over one acre (and in many cases all size developments) to minimize the discharge
of pollutants into waterways. Records are kept within each regulatory agency office.

D5. Public Information Handling Procedures
Goal:
DuPage County Citizen Reporter App allows residents throughout the partnership area to report water quality
issues, including soil erosion and sediment control complaints. The County addresses complaints within
unincorporated and non‐waiver areas. Complaints generated from Full Waiver or Partial Waiver Communities
are forwarded to the Municipality. The County and Municipalities also receive and respond to soil erosion and
sediment control concerns sent directly from the public.
Milestone:
Investigate and track all soil erosion and sediment control reports to the County and Municipalities each year.
Status:
Reports regarding soil erosion and sediment control from developments are submitted to the County as well
as municipalities. Co‐permitees communicate with one another to share reports and locate possible sources
from development sites. All soil erosion and sediment control complaints were investigated by the County or
the municipality during the reporting year. Records are kept within each regulatory agency office.

D6. Site Inspection/ Enforcement Procedures
Goal:
Inspect all development sites to ensure the soil erosion and sediment control requirements are being met.
Milestone:
County and Municipal inspectors enforce soil erosion and sediment control regulations and conduct regular
inspections to ensure compliance. Inspection reports are kept within each regulator agency for tracking and
reporting purposes. Continue with site inspections and code enforcement procedures. Ensure staff has proper
qualifications to conduct soil erosion and sediment control inspections.
Status:
Under the DuPage County Countywide Stormwater and Flood Plain Ordinance, co‐permitee villages and cities
may elect to review and inspect development sites for soil erosion and sediment control, or they may elect to
defer oversight to DuPage County. Each co‐permitee that issued development permits inspected for soil
erosion and sediment control measures at sites over one acre (and in many cases all size developments) to
minimize the discharge of pollutants into waterways. Records are kept within each regulatory agency office.

E. Post‐ Construction Runoff Control
E2. Regulatory Control Program
Goal:
The post construction runoff rate is restricted through the Countywide Ordinance which requires all
developments increasing impervious area by 2,500 square feet or more to include Post Construction Best
Management Practices.
Milestone:
Continue to require post construction best management practices in accordance with the Countywide
Ordinance. Implementing and utilizing the DuPage County BMP Manual will reduce post construction runoff
pollutants and will ensure discharge from developed sites will be treated. Work through the Municipal
Engineers Group to update Technical Guidance regarding Post Construction BMPs. Review and revise the
Ordinance and/ or BMP Manual as needed to reflect new information and standard practices.
Status:
The DuPage County Countywide Stormwater and Floodplain Ordinance (DCCSFO) is continually reviewed to
determine if updates are needed. As the DCCSFO is a countywide ordinance, the regulations apply to the
entire county and all municipalities must be at least as stringent as the DCCSFO. Following review and
discussions, staff determined the BMP section of the DCCSFO will require an update. This revision is being
discussed and evaluated with cooperation from co‐permitee agencies and revision is planned for 2021.
A subgroup to the DuPage County Municipal Engineers group was created to provide technical assistance and
guidance materials. This subgroup generated sample specifications for a dry well, permeable paver system,
and rain garden which has been made available online. The samples are used as a template for the design of
these practices on residential properties. The group continues developing inspection checklists for long term
maintenance and monitoring which are scheduled for completion in 2021.

2021 ANNUAL FACILITY INSPECTION REPORT
E3. Long Term O&M Procedures
Goal:
The Ordinance requires site runoff storage facilities to be put into an easement. All Post Construction BMPs
with a tributary area greater than one (1) acre require a three‐year maintenance and monitoring period.
Milestone:
Require and accept easements over site runoff storage facilities and maintenance and monitoring periods for
BMPs with a tributary area of one acre or more.
Status:
Under the DuPage County Countywide Stormwater and Flood Plain Ordinance, co‐permitee villages and cities
may elect to review and inspect development sites or they may elect to defer oversight to DuPage County.
Each co‐permitee that issued development permits required easements over site runoff storage facilities and
required three‐year maintenance and monitoring periods for BMPs on sites with a tributary area of over one
acre (and in many cases all size developments) to minimize the discharge of pollutants into waterways.
Records are kept within each regulatory agency office.

E4. Pre‐Construction Review of BMP Designs
Goal:
The DuPage County Countywide Stormwater and Flood Plain Ordinance requires developments to provide post
construction BMPs when impervious cover thresholds exceed 2500 square feet.
Milestone:
The DuPage County BMP Manual provides guidance on the design and implementation of development
practices that prevent stormwater quality degradation and enhance the overall quality of stormwater. The
BMP Manual promotes and gives guidance on the installation of vegetated filter strips, vegetated swales,
infiltration systems, permeable pavers, manufactured structures, and stormwater detention BMPs such as dry
detention basins, wet detention basins, constructed wetland detention basins, and underground detention
basins. Review site development plans for compliance with the BMP sections of the Ordinance and document
number of reviews
Status:
Under the DuPage County Countywide Stormwater and Flood Plain Ordinance, co‐permitee villages and cities
may elect to review and inspect development sites or they may elect to defer oversight to DuPage County.
Current waiver status is shown in the table in Section D.2. Each co‐permitee that issued development permits
required post construction BMPs on sites when impervious cover thresholds exceeded 2500 square feet (or
less in some communities). Records of numbers of reviews are kept within each reviewing agency.

E5. Site Inspections During Construction
Goal:
The DuPage County Countywide Stormwater and Flood Plain Ordinance requires that permitting authorities
utilize a qualified person with expertise in plant ecology for design review and construction observation of Post
Construction BMP installations which rely on vegetation for water quality or runoff volume reduction and a soil
scientist or geotechnical engineers or equivalent be utilized for infiltration BMPs. Each permitting agency
reserves the right to inspect the construction site during construction to verify proper BMP installation for
enforcement purposes.
Milestone:
DuPage County Stormwater will provide annual training opportunities for all permit partners staff to ensure
that all MS4 employees and contractors who manage or are directly involved in routine maintenance, repair, or
replacement of public surfaces in current green infrastructure or low impact design techniques applicable to
such projects to ensure that they are able to identify proper BMP installation during construction. Appropriate
staff of each partner agency shall attend training on green infrastructure and low impact design.

Maintenance is conducted at our yard. inspection and maintenance are conducted on a
regular schedule. Several areas of turf grass were converted to native vegetation, including
the Schick Road Bike Path, the Road District yard, Glenwood and Waynewood, in addition to
several other smaller bioswale areas.
The Wayne Township Road District is committed to leading the township in water quality,
primarily by installing and maintaining green infrastructure practices throughout our area.
Many of these areas were erosion issues before conversion, and they now provide filtration
and infiltration of water and pollutants. Maintain Road District owned property on which
native vegetation was established for pollutant control purposes. These properties typically
contain riparian, wetland, or floodplain areas or post‐construction best management
practices. The Township will also be converting more areas to native vegetation and they will
be maintained as part of this BMP.
Westmont The Village has completed a regional detention facility at Cass Avenue and 61st Street

F4. Municipal Operations Waste Disposal
Goal:
The ILR40 permit requires that procedures be developed for properly disposing of waste removed from the
separate storm sewers and areas such as dredge spoil, accumulated sediments, floatables and other debris.
Milestone:
Following storm sewer maintenance and cleanout activities, waste must be properly disposed of. DuPage
County Public Works offers a Regional Vactor Receiving Station. The station is part of a shared services
initiative. It reduces the cost of disposal of public works waste and aims to keep pollutants out of area water
supplies. The station processes the debris collected by public works and transportation vacuum tanker trucks.
The waste is then separated into liquids and solids. The liquids are treated through the county’s waste water
treatment facility, while the solids are dried and eventually transferred to the garbage dump.
Status:
During the first reporting year, co‐permitees continued current practices to properly dispose of waste
generated from storm sewer maintenance and cleanout. DuPage County continued to offer disposal facilities
such as the Regional Vactor Receiving Station.

F6. Other Municipal Operations Controls
Goal:
Evaluate and encourage pre‐wetting and anti‐icing measures to reduce chloride runoff into waterways from
roads and public surfaces.
Milestone:
Deployment and use of pre‐wetting and anti‐icing measures by partner agencies. Survey partner agencies on
pre‐wetting and anti‐icing practices.
Status:
During the reporting year, DuPage County and co‐permitees continued current practices for snow and ice
removal on roads and public surfaces. More information on the chloride reduction efforts can be found in the
DRSCW and co‐permitee attachments.
As monitoring ambient chloride concentrations has proven an imperfect metric for tracking efficiency trends
in winter salt use the DRSCW has attempted to track adoption of sensible salting BMPs in the program area
since 2007. Tracking target BMP adoption in the program area provides opportunities to evaluate the impacts
of the chloride management workshops, identify material for future workshops, and form suppositions about
salt use per unit of service expended inside the program area relative to 2006 levels.
In 2007, 2010, 2012, 2014, 2016, and 2018 the DRSCW distributed a questionnaire to approximately 80
municipal highway operations and public works agencies to obtain information about deicing practices
throughout the program area. Findings of the 2018 questionnaire were include in the 2018 Annual Report. A
new questionnaire will be distributed in spring of 2021 and the results will be supplied in the 2021 MS4
