US District Judge issues Consent Order canceling April 14th hearing.

County's statement on order:

Marietta, GA -- The County has mutually agreed with Sterigenics to maintain the status quo under the existing Temporary Restraining Order (TRO), in light of the ongoing pandemic health crisis and emergency orders. A hearing on the TRO will occur at some point in the future regarding the operating status of the facility and its necessary occupancy and hazardous classifications.  

The County stands behind the work exhibited by our Fire Marshal and Chief Building Official in their continued efforts to protect the County’s public from potential hazards and harms, regardless of origin.   Public Safety has always been, and will remain, the County’s focus regarding this issue.

Consistent with county code and internal county procedures, Cobb County officials plan to allow Sterigenics to conduct previously-delayed negative air pressure testing on their building.   This test does not involve the use of ethylene oxide and is not a prelude to the facility re-opening.

“We recognize that Sterigenics could assist the community in combating COVID 19,” said County Manager Rob Hosack.  “However, several critical steps must be completed before Sterigenics can safely reopen and comply with fire safety codes and other county ordinances as has been shared with Sterigenics.”

Sterigenics may conduct this testing in the next few days, the results of which will go to the state Environmental Protection Division officials who will then analyze the results.

Cobb County officials are waiting on the results of a third-party expert’s investigation into Sterigenics’ operation and how the facility can comply with the latest fire codes.

“We understand the gravity of the current situation,” Hosack said, “but we also need to ensure the safety of our residents and with that in mind we need to carefully move forward.”

Cobb County issues a statement regarding the ongoing investigation into Sterigenics' Certificate of Occupancy

There have been conflicting statements made about work going on at the Sterigenics facility and the current status of operations there.

Any work that has happened at the facility since construction permits were pulled in October of 2019 were tasks that do not require permitting.  Any business in the county is allowed to do routine maintenance on their buildings in most cases without getting any permission from the county.

The airflow testing Sterigenics requested last month was an operation that did not require permitting and did not involve the use of any ethylene oxide. 

Prior to the test, county officials and Sterigenics began a discussion about removing ethylene oxide from the facility and those discussions continue.  The airflow test was subsequently canceled.  

The issues surrounding whether Sterigenics can store and use ethylene oxide at that site, and if so how much, is the subject of continuing work by a third-party expert.   That analysis has proven to be more complicated than initially thought.  The results of the report will determine the path forward in regards to Sterigenics’ Certificate of Occupancy at that site and any pending construction permits.

Please remember that there are no current sterilization operations at the facility due to the actions of the county.  The safety of our residents is our utmost concern and we are taking every step possible to ensure compliance with all applicable fire and building codes.  But it is a long and complicated process that continues.


February 19, 2020

A scheduled airflow/negative air pressure test at the Sterigenics facility on Olympic Industrial Drive will not happen Thursday as originally planned.  Officials with the state Environmental Protection Division reached out to county officials seeking a new authorization for the test after receiving conflicting information about whether further permitting or inspections were needed.  County Manager Rob Hosack indicated it would take some time to specifically address the concerns. 

The planned test did not involve the use of ethylene oxide and was not a prelude to the company resuming operations.  The test addressed issues with state environmental emissions regulations per a consent order.  Work between Sterigenics and an independent third-party engineering firm to address fire code and safety issues with Cobb County continues.  The third-party expert has not yet generated a report and there is no timetable for completion of the highly-technical report. Both parties are still trading information as part of that investigation. No sterilization is occurring at the facility.  

Cobb Chairman Mike Boyce expressed frustration with the situation and reiterated residents need to be notified farther in advance before any action at the plant takes place.

Commissioner Bob Ott, who represents the area in District 2, released the following statement:

I found out late last night about the proposed testing by Sterigenics.  I immediately reached out to the Governor’s office to get EPD to stop this testing and force Sterigenics to comply with county rules and codes.  Although the testing involves a test of the negative pressure system of the facility and is not using any ethylene oxide, it is unacceptable for Sterigenics to proceed without approval or permits from the county and the state.

Through the efforts of the governor’s office and with coordination of Ga EPD the testing has been canceled pending Sterigenics obtaining the necessary permit and inspections of the negative pressure system.  I will continue to keep you informed of the situation as it progresses.


Georgia Environmental Protection Division has postponed a planned negative air pressure test at the Sterigenics facility.  Information from EPD:


On October 9, 2019, EPD issued a letter to Sterigenics outlining testing protocols that must be fulfilled prior to issuance of a permit,  That letter requires Sterigenics to obtain necessary approvals from Cobb County prior to any testing activity. 

On February 14, 2020, Sterigenics notified EPD that Sterigenics will be conducting the flow and pressure testing of the negative pressure system on February 20, 2020.  This is in reference to Condition #5 in the October 9th letter, “Demonstrate that the Indoor Air System enclosure meets 100% capture.”  This test does not include the use of ethylene oxide.    

EPD is seeking confirmation from Cobb County that Sterigenics has the necessary county approvals to conduct this testing.   


We are waiting on word from Cobb County that all necessary approvals have been met.  We don’t expect that today, so the testing will not occur tomorrow.


February 18, 2020

We are aware that Sterigenics plans a test of a system that does not require the use of ethylene oxide.  This test is being done to fulfill state requirements and will not involve the use of ethylene oxide. 

Cobb County will not allow Sterigenics to resume the use of ethylene oxide for any purpose until the County has completed all of its Public Safety diligence.  

This does not change anything about the current work of the third-party expert investigating Sterigenics occupancy status at that facility, and the county’s belief that a “high hazard” status is warranted.  That work continues and Sterigenics currently does not have the county’s approval to resume operations.


February  4, 2020

In response to some inquiries, the work involving an independent third party and Sterigenics over fire code issues is continuing.  No report has been generated yet as that expert continues to request more information from the company.


December 2, 2019

In reference to some recent questions about activity at the Sterigenics facility on Olympic Industrial Drive. 

Cobb County officials are aware that workers are finishing some minor modifications to their facility. This work involves the building’s HVAC system and is necessary to allow for future inspections of the facility.  The company and county officials have been in contact concerning the work.  Work to sort out issues surrounding the facility’s Certificate of Occupancy continues.  

The facility has not been cleared to resume operations.

Commissioner: Cobb Requires Sterigenics to Remain Shut Down Pending Review
Fire Marshal’s change of Occupancy Status likely to bring new requirements

Marietta - Sept 26 |  District 2 Commissioner Bob Ott says county officials will send Sterigenics a formal notice mandating that the company remain shut down during a review of the permitting process and fire protection standards.

“The review is fairly technical,” Commissioner Ott said, “so what the Fire Marshal is doing is bringing in an outside consultant per the National Fire Protection Standards (FPS) and that person will help the county determine exactly what the fire protection standards need to be and that will be passed on to Sterigenics.”

Ott believes the reviews could take several weeks.  Sterigenics voluntarily shut down in late August to begin work on installing advanced equipment to reduce their emissions of ethylene oxide.  The chemical is used in a medical sterilization process but has recently been classified as a carcinogen by the EPA.

Ott said the Fire Marshal noticed the company’s occupancy status was outdated when they recently applied for a construction permit.  The change to an “industrial” status could bring with it additional code requirements that could apply to Sterigenics.

An Oversight Committee compromised of members from Smyrna, Cobb County, and the City of Atlanta formed to conduct independent air testing around the plant.  Smyrna Mayor Max Bacon, the committee’s chair, said today the testing effort will remain paused until Sterigenics resumes operations.

VIDEO UPDATE - The Oversight Committee formed to conduct independent air monitoring around Cobb’s Sterigenics plant received their first report today.  The environmental engineering company GHD briefed the group on the first three days of testing. Watch the video to find out more. Some important details:

• The tests were conducted while the Sterigenics plant was NOT operating.

• 80% of the monitors positioned in Smyrna, Cobb, and Atlanta did NOT detect ethylene oxide.

• Those monitors that DID detect ethylene oxide matched what is considered “background” readings found in much of the country.

• Testing has paused but will resume after the Sterigenics facility resumes normal operation.

The independent air testing effort has temporarily halted due to Sterigenics construction and operations shutdown.   Smyrna Fire Chief Roy Acree:  "In our efforts to conduct independent air sampling, we currently have a full week of data. We will resume ambient air sampling after production resumes at Sterigenics."


September 6, 2019

Sterigenics plans to expedite construction on emissions controlling measures, meaning production will largely be halted until next month.

Cobb Statement: 

Smyrna, GA (September 6, 2019) -- Sterigenics officials had notified the Smyrna - Cobb County - City of Atlanta oversight committee about their proposal to suspended production during construction work at their facility this month.  The planned work is not expected to significantly alter the task force’s work to independently monitor the air for ethylene oxide emissions.

Smyrna Mayor Max Bacon, who is chairing the Oversight Committee, said the Task Force conducting the testing had already made provisions for this situation.

“We’re aware of the operational shutdown at the facility,” Mayor Bacon said.  “The Task Force had already taken this into account during their planning and those involved assure us it will not negatively impact our efforts.”

The Task Force, working with the firm GHD Services, began positioning air monitors this week.  Smyrna, Cobb County, and the City of Atlanta have joined to form the effort to independently test the amount of ethylene oxide in the air surrounding the Sterigenics facility.

Sterigenics plans plant operation changes during construction:

"In order to expedite the installation of enhancements at its Atlanta facility, Sterigenics is altering production schedules at the facility to ensure timely execution on construction.  During this period, Sterigenics periodically will shut down production and/or reduce production as construction needs dictate.   We are working with our customers during this period to minimize any impact on the supply of sterile medical products to healthcare professionals and the patients who need them."

Cobb County statement responding to Sterigenics plan to alter production schedules:

"Sterigenics has agreed to provide the joint Smyrna/Cobb/Atlanta Oversight Committee with the dates and times of altered production schedules that could affect emissions and alter the Committee's intentions when it comes to the timing of independent air testing.  The committee, working with the GHD company, will address the situation accordingly."

Cobb Leaders Join Smyrna Effort to Test Air Near Sterilization Plant
An Oversight Committee will seek experts to do independent testing

Smyrna, GA - August 6, 2019 |  Cobb County leaders say they’ll accept an invitation from Smyrna’s mayor to join an effort to conduct independent air testing near a medical sterilization plant in District 2.   Smyrna Mayor Max Bacon asked County Manager Rob Hosack and Commissioners Bob Ott and Lisa Cupid to join an Oversight Committee that will include residents, business leaders and others from both the city and county.

The effort comes after a report raised concerns about Ethylene Oxide released from the Sterigenics Plant off Atlanta Road.  The EPA considers Ethylene Oxide a cancer-causing chemical, but Georgia’s Environmental Protection Division has said Sterigenics is “in compliance with current federal requirements for control of ethylene oxide emissions.”

“We need to make sure the community is protected, that people are safe,” said Mayor Bacon.  “The key is getting this going, getting the air tested and see where we go from there.”

The committee will include city and county officials, health experts, and other local stakeholders who will work with an Independent Air Quality Task Force of private technology experts to quickly implement a plan to test the air near Sterigenics and analyze the results.

A small group met with representatives of GHD, the company who did independent testing around the Sterigenics plant in Willowbrook, Illinois.  The company said testing could be set up in a few weeks, with some initial results a few weeks after that.  The committee will also reach out to officials in Atlanta to see if they would like to expand testing there.

“This is a great opportunity for the City of Smyrna and Cobb County to work together to give residents what they’ve been asking for; independent testing,” said Cobb Commissioner Bob Ott.  “This quick action shows the great relationship between the city and county.”

Statement from State Senator Jen Jordan on Sterigenics

As I indicated yesterday, disturbing reporting by Georgia Health News and WebMD revealed that Georgia’s Environmental Protected Division (“EPD”) has kept the public in the dark about an elevated cancer risk caused by the emission of ethylene oxide in the metro-Atlanta area.

This morning, with Rep. Erick Allen, I spoke with the President of Sterigenics and he has represented to me that the company will be submitting an application to Georgia EPD within 7 to 14 days that will seek EPD's approval for Sterigenics to install new emissions-reducing technology in its Cobb County plant that the company believes will significantly reduce emissions and bring down any emissions to an acceptable level.

If its application is approved by EDP, Sterigenics believes that the installation of the new emissions-reducing technology would then take approximately 12 weeks to complete. The company has said that it would put out a formal statement by the end of the day. Rep. Allen and I will post the statement once we have it in hand.

To be clear, these initial overtures are welcome, but they are just the beginning and will not cut off my office's efforts to ensure that the people that live in my district are not being harmed. I know that there is a lot of troubling information out there, but just know that we are working to get answers and solutions.


July 23, 2019

Commissioner Bob Ott’s office has reached out to state Environmental Protection Division officials after residents expressed concern about a medical equipment facility operating in a nearby Heavy Industrial area.

A recently-published article indicated the Sterigenics facility off Atlanta Road near the Chattahoochee River emits a gas that has been linked to cancer.  

“The county understands the concerns of people who live in the area,” said Commissioner Ott.  “Both my assistant and others with the county have had multiple conversations with Georgia EPD officials since the article came out and want to make sure the state is doing everything it can to monitor emissions from the plant.”

Ott’s office confirmed the Sterigenics facility is operating legally in an area zoned for heavy industrial use.  The company did not receive any incentives or tax breaks to locate there.

Georgia EPD officials tell us the company is currently in compliance with state regulations and has told them they are installing additional emission controls at their own cost.

The concerns were raised not because the plant is releasing more ethylene oxide gas, but because the US Environmental Protection Agency recently identified the gas as a carcinogen.  State EPD officials told Commissioner Ott’s office that since that change, new testing and analysis has been underway with results expected in the next few months.

“Even though the state has authority in monitoring emissions coming from the plant, I think it is important the county makes sure residents in the area get their questions answered and are briefed on any new results as soon as possible,” Ott said.
