Summary
EPA required air monitoring at Sims Metal Management because we want the community to have clean air. EPA understands that the community has environmental justice concerns, and we want to be responsive to them. EPA is requiring monitoring to hold Sims accountable while its new controls that will reduce emissions are installed—after which City of Chicago rules will require continued monitoring for PM10. EPA will continue to require air monitoring until the new controls are installed and we determine that the controls are operating as intended. In partnership with Illinois EPA and the City of Chicago, EPA will continue to work with this community to improve air quality.
Background
On April 21, 2022, EPA issued a Clean Air Act 114(a) Request for Information (RFI) to Metal Management Midwest Inc. (doing business as Sims). The RFI required the company to install and operate air pollution monitors at its metal shredding and recycling facility at 2500 S. Paulina Street, Chicago, Illinois. The monitoring will help EPA assess the company’s compliance with the Clean Air Act (CAA).
Under the requirements of the CAA Section 114 RFI, Sims is required to continue monitoring until the new controls are installed and the agency is able to determine that the controls are operating as intended—after which City of Chicago rules will require continued monitoring for PM10. As Sims submits additional data, EPA will continue to evaluate for potential risk.
The pollution monitors:
- continuously monitor real-time PM10—at all five locations, hourly data; and
- sample for eleven multiple metal Hazardous Air Pollutants (HAP)—at three locations (AQ1, AQ2, AQ5), 24-hr sample every third day; and
- sample for Volatile Organic Compounds (VOC)—at three locations (AQ1, AQ2, AQ5), 24-hour sample every third day.
EPA reviewed and approved the company’s monitoring and quality assurance plans and the five monitors began operating on September 23, 2022. EPA inspected Sims on October 4, 2022 to address a citizen complaint and check on the air monitors. The inspection report is available below.
Sims submits monthly reports to EPA with air monitoring, quality assurance, and facility operational data. EPA closely reviews monthly submittals and routinely follows up with Sims as questions arise during EPA’s review of the data. EPA compares the reported PM10, metals and VOC data to health benchmarks, including the National Ambient Air Quality Standards (NAAQS) and Minimum Risk Levels (MRLs).
The NAAQS are established by EPA to protect public health, including the health of sensitive or at-risk groups (including children), with an adequate margin of safety. They are set for six criteria pollutants, including PM, ozone, nitrogen dioxide, sulfur dioxide, and lead. EPA works with states to ensure areas are in attainment with the standards through air quality planning, permitting, and enforcement.
MRLs are an estimate of the level of a chemical that a person can breathe without a detectable risk to health. The acute MRL is based on a 1–14-day exposure for non-cancerous health effects. The chronic MRL is based on an exposure greater than 365 days. MRLs are screening tools used by public health professionals and are not intended to serve as definitive action levels. Exposure to a level above the MRL does not mean that adverse health effects will occur. Rather, it indicates a need to investigate the situation further.
Facility Map and Windrose
The following map identifies the facility boundaries, locations of processes at the facility, and locations of the air pollution monitors. The accompanying wind rose shows the predominant wind directions during the duration of this monitoring study, based on data on wind speed and direction collected on site at Monitor AQ1. The circular format of the wind rose shows the direction the winds blew from and the length of each "spoke" around the circle shows how often the wind blew from that direction. For example, the wind rose below shows that during this sampling period, the wind blew from the southwest more than 15 % of the time, etc. The different colors of each spoke provide details on the speed, in meters per second (m/s), of the wind from each direction.
| Monitor | PM10 | Metals | VOC | Wind Speed and Direction |

PM10 and Production Data Visuals
The graphs below represent all quality-assured daily 24-hour averaged PM10 and production data from Sims. PM10 values that did not meet EPA’s quality assurance/quality controls standards have been excluded from the graphs. The horizontal line indicates EPA’s PM10 NAAQS. To attain the standard, a monitor’s 24-hour average concentration cannot exceed 150 µg/m3 more than once per year over three years.
More information about PM concentrations and health impacts can be found on the Air Quality Guide for Particle Pollution (pdf) (2pp, 197KB) on the AirNow webpage.
The period when smoke from Canadian wildfires may have affected air quality in Chicago has been grayed out. Smoke from wildfires, even from wildfires hundreds of miles away, can significantly affect air quality and impact human health. Smoke is made up of a complex mixture of gases and PM, produced when wood and other organic materials burn. To learn more about wildfires and air quality, visit EPA’s Smoke-Ready Toolbox for Wildfires.
Sims provides EPA with each month’s production information. This includes the hours the shredder and metals recovery plant (MRP) are in operation, and information about the scrap delivery methods (rail, truck, and barge).
Acrolein
After careful review, EPA has determined that the acrolein data are unreliable and should not be used for any analysis. Since 2010, EPA has known that acrolein is difficult to measure in the air. It can react easily with other chemicals to form other compounds that complicate laboratory analysis. Acrolein is not emitted from metal shredders, like Sims, and there are no nearby facilities that emit acrolein. For transparency, EPA is posting the acrolein data reported by Sims and is requesting that Sims flag future acrolein data. EPA will continue to analyze future acrolein levels for accuracy.
Long-Term Health Impacts
Now that over a year of data has been collected, EPA has evaluated whether the measured levels of PM10, metals, or VOC could cause any long-term health effects. EPA has found that if monitoring data collected over the last year represent typical levels, emissions from Sims would not cause either short- or long-term health effects for the community near the facility. To make this determination, EPA compared the monitoring results to current health benchmarks. Monitored concentrations of pollutants were below both short- and long-term health benchmarks. EPA will continue to assess the potential for any health impacts with each new data submission from Sims.

May 2023 Data Summary (posted on 09/20/2023)
Production Data: In response to EPA’s request for information, each month, Sims provides EPA with information about hours the shredder is in operation, scrap delivery methods and times, etc. EPA has made this information available:
May 2023 Production-Rail-Truck Barge (xlsx)
VOCs: Concentrations for all measured pollutants are below levels that would cause human health effects from short-term exposure to the air in the area around the facility. As noted above, there is one sample collected and analyzed in May that contained an elevated value of one air pollutant called acrolein.
EPA is carefully assessing whether the acrolein data being reported is accurate. Since 2010, EPA has been aware of challenges associated with measuring ambient air concentrations of acrolein, which may be affected by canister cleaning methods and gas standards1. Given the challenges of accurately measuring acrolein, EPA is verifying these concentrations with the laboratory. EPA will update this website as additional information is known.
Acrolein is a chemical that can enter the air when trees, tobacco, gasoline, or oil are burned. Cigarette smoke and automobile exhaust also contain acrolein. EPA identified one sample of acrolein that measured 4.16 ppb on May 15, 2023, which exceeded the acute (short term) Minimum Risk Level (MRL) of 3 ppb. This is the second monitored exceedance of the MRL for acrolein during this monitoring effort: the first exceedance of 4.60 ppb occurred on November 7th, 2022.
PM10: All 24-hour average PM10 concentrations collected in May are below EPA’s health-based PM10 standard of 150 µg/m3 over a 24-hour period.
Lead and other metals: Concentrations of lead, manganese and chromium were detected below levels that would cause short- or long-term health impacts. As Sims submits additional data on metal hazardous air pollutants, EPA will evaluate for potential risk.

February 2023 Update (posted on 02/13/2023)
On January 28, 2023, EPA received Sims’ monitoring and sampling data for December. Additionally, on February 7, 2023, EPA received hourly PM10 data for February 4, 5 and 6 to evaluate potential air quality impacts from a scrap pile fire at the facility on Saturday, February 4.
The available, quality-assured monitoring data shows no pollutant concentrations that would cause human health effects from short-term exposure to the air in the area around the facility. More data is needed to evaluate long-term risks. As Sims submits additional data, EPA will continue to evaluate both short- and long-term risks.
Update on Sims’ February 4, 2023 fire: On February 6, 2023, U.S. EPA contacted Sims about air emissions from the scrap pile fire that occurred at about 4:00pm on Saturday, February 4. Although Sims is not required to provide U.S. EPA with February air monitoring data until March 30, Sims provided all available air monitoring data for February 4, 5, and 6, 2023. PM10 concentrations at the north monitor were elevated for a two-hour period that coincided with the fire, but the 24-hour PM10 average remained below EPA’s health-based standard. All other PM10 monitors were not elevated, which corresponds to the wind direction during the fire.
Samples of VOCs, lead and other metals are collected every third day on a set schedule. The fire occurred on a day when these samples were not collected, so data for these pollutants during the fire will not be available.
A U.S. EPA inspector visited Sims on February 6, and confirmed that the fire has been extinguished. The inspector also checked for any fire-related odors or smoke and did not observe any.

VOCs: Concentrations are below levels that would cause human health effects from short-term exposure to the air in the area around the facility. EPA needs more data to evaluate long-term risks. As Sims submits additional VOC data, EPA will continue to evaluate both short- and long-term risks.
PM10: All 24-hour average PM10 concentrations are below EPA’s health-based PM10 standard of 150 µg/m3 over a 24-hour period. EPA did observe a limited number of hourly values that were above 150 µg/m3. Though still below the health-based standard, EPA is analyzing the cause of these higher values. As Sims submits additional PM10 data, EPA will continue to compare the reported levels with the health-based standard.
Lead and other metals: Air samples did not have lead concentrations high enough to be detected. “Not detected” should not be interpreted as meaning that the pollutant is not present. Rather, the pollutant could be present, just not at levels that the monitors could detect. “I’” indicates an issue with the sample collection or analysis that prevents results from results from being interpreted.
Since 24-hour lead concentrations were below the detection level of 0.035 µg/m3, they are also well below EPA’s health-based standard 0.15 µg/m3 over a three-month average. The other metals concentrations were also below detection limits. As Sims submits additional data on metal hazardous air pollutants, EPA will evaluate both short- and long-term risks.

September 2022 Data Update (posted on 11/21/2022)
On October 31st, EPA received Sims’ monitoring and sampling data for September 23 - 30, 2022. Below is EPA’s review of the data. Separately, EPA has noted some instances where the monitoring equipment was not operating properly, and we have provided this information to Sims so that they can address the problems.
The available, quality-assured monitoring data from September shows no pollutant concentrations that would cause human health effects from short-term exposure to the air in the area around the facility. More data is needed to evaluate long-term risks. As Sims submits additional data, EPA will continue to evaluate both short- and long-term risks.
Health Impacts and Results: The primary pollutants of concern from metal shredders are volatile organic compounds, or VOCs, and particulate matter, or PM, which can contribute to respiratory illness. PM emissions can also include hazardous metals – particularly lead. EPA’s Clean Air Act 114(a) information request required Sims to monitor these air pollutants before installing its new pollution-control equipment. This control equipment will help achieve significant reductions in VOC and PM emissions.
VOCs: EPA reviewed the September VOC data and concluded that the concentrations are below levels that would cause human health effects from short-term exposure to the air in the area around the facility. EPA needs more data to evaluate long-term risks. As Sims submits additional VOC data, EPA will continue to evaluate both short- and long-term risks.
PM10: EPA concluded that the September 24-hour average PM10 concentrations are all well below EPA’s health-based PM10 standard of 150 µg/m3 over a 24-hour period. The 1-hour concentrations were also all below this level. As Sims submits additional PM10 data, EPA will continue to compare the reported levels with the health-based standard.
Lead and other metals: September’s air samples did not have lead concentrations high enough to be detected. Since lead concentrations were below the detection level, they are also well below EPA’s health-based standard. The other metals concentrations were also below detection limits. As Sims submits additional data on metal hazardous air pollutants EPA will evaluate both short- and long-term risks.
September 2022 Data Summary (posted on 11/04/2022)
On October 31st, EPA received Sims’ monitoring and sampling data for September 23 - 30, 2022. Consistent with the terms of EPA’s April 2022 request for air data, Sims provided VOC and metal HAP sample results for three days from three locations and continuous PM10 monitoring data from five locations.
EPA has reviewed the September VOC data and concluded that there are no public health effects from short-term exposure to the air in the area around the facility. Not enough data is available at this time to evaluate longer-term risks. As Sims submits additional VOC data, EPA will continue to evaluate both short- and longer-term risks.
After reviewing the September metal HAP and PM10 data, EPA has concerns that the monitoring equipment did not work as designed. Specifically, EPA is concerned that the monitoring equipment may have pulled in either too much or too little air, potentially invalidating the results. Air flow rate is important for accurate monitoring results because it is used to calculate the final concentrations of pollutants. EPA has not received October data and does not yet know if the October data will present similar concerns. The October data is due to EPA by November 30.
EPA will continue to evaluate the September metal HAP and PM10 data to determine if it can be used. EPA is also working to ensure that future data will meet quality standards. EPA is in discussions with Sims and its third-party monitoring contractor to address these issues and is arranging an on-site technical assistance visit.
