The Delaware Department of Natural Resources and Environmental Control (DNREC), along with state and federal partners, will hold a virtual meeting at 6 p.m. Wednesday, April 13 regarding ethylene oxide (EtO) – with the meeting’s focus on public health and safety concerns over Croda, Inc.’s EtO production in the New Castle area. Information will be presented by DNREC, the U.S. Environmental Protection Agency, the Delaware Division of Public Health, and Croda Inc., which manufactures EtO at its Atlas Point facility.

The information will include health data, risk estimates, facility updates and ongoing activities to address the emissions from Croda’s EtO plant. Afterward, attendees will have the opportunity to ask questions and have them answered by staff from DNREC and partnering agencies, and by Croda officials. Questions also can be submitted prior to the virtual meeting by email to daqpermittinginfo@delaware.gov.

Additional information about EtO and the virtual meeting is available at de.gov/EtO.

The Delaware Department of Natural Resources and Environmental Control announced an agreement today with Croda Inc., that requires the company to take actions protective of human health and the environment in addressing recent violations at Croda’s Atlas Point facility near New Castle.

In November 2020, DNREC announced violations at the ethylene oxide (EO) plant, including excess emissions of EO. In January 2021, Croda restarted the facility in order to conduct stack testing. While testing showed that the company was back in compliance with the EO emissions, it revealed violations for nitrogen oxide (NOx) at the ethanol dehydration furnace (EDF). Further violations were detected at the catalytic combustion unit (CCU) for carbon monoxide (CO), volatile organic compounds (VOCs) and particulate matter (PM). Additionally, the agreement with DNREC addresses violations at the Atlas Point facility that Croda disclosed in its July 2020 semiannual report.

According to the settlement agreement between Croda and DNREC, Croda will meet a schedule to complete construction to remove the hotwell as a source of emissions and re-route emissions from the EO scrubber to minimize or eliminate emissions from this source. Croda will apply to increase emissions at the EDF and all increases will be offset with concurrent permitted decreases at a 1:1.3 ratio. Prior to restarting the EO Plant, Croda will replace the catalyst at the CCU to improve operation of this unit and return to compliance. They will install a flue gas analyzer to measure carbon monoxide (CO) to continuously confirm catalyst performance within 30 days of the EO plant restart. Additional stack testing will be conducted within 60 days of restarting the EO plant to set operating conditions and ensure compliance with emissions limits.

In addition, Croda will pay a penalty of $300,000 and install a community alarm system to the north of Interstate-295, expanding the environmental emergency notification range should the facility be responsible for hazardous releases in the future. The agreement between DNREC and Croda can be found on the DNREC website at https://dnrec.alpha.delaware.gov/secretarys-orders/enforcement/.

A virtual public information session will be held March 3 by DNREC to answer questions and take community comments about Croda’s operations and about the agreement with DNREC. Questions from the public can be emailed in advance to daqpermittinginfo@delaware.gov. Registration for the public information session can be made on the DNREC website. Croda intends to restart the plant no sooner than the end of next week.

DNREC previously posted a list of questions/answers following a November 2020 public information session – they are available on the DNREC website, as is the Nov. 11, 2020 Notice of Violation issued to Croda.

DOVER – The Delaware Department of Natural Resources and Environmental Control (DNREC) and Croda, Inc. have entered into a settlement agreement that resolves environmental violations arising from the Nov. 25, 2018 ethylene oxide release (EO) at Croda’s Atlas Point facility.

Croda, Inc.’s facility located at 315 Cherry Lane, New Castle, Del., manufactures surfactants that promote mixing of oil- and water-based ingredients in consumer products such as pharmaceuticals and shaving cream. At 4:23 p.m. on Sunday, Nov. 25, the EO release by Croda was responsible for a seven-hour shutdown of the Delaware Memorial Bridge while emergency responders – including DNREC’s Emergency Prevention and Response Section and Environmental Crimes Unit – worked throughout the area to ensure that there was no threat to public health and safety.

Croda’s subsequent investigation found that the release was due to the failure of a gasket made of unsuitable material for processing EO at the plant. The accidental release resulted in 2,688 pounds of the highly flammable EO gas escaping into the environment. A water deluge system, deployed by Croda to minimize the risk of ignition or explosion of the EO that was released, caused almost 700,000 gallons of deluge water to overflow a spill sump and to discharge into the ground and a wooded area behind the sump.

The settlement agreement includes a DNREC Secretary’s Order issued on March 4, 2019, citing Croda for Division of Air Quality violations for the EO release and for the improper maintenance and operation of the Atlas Point facility. The Division of Water cited Croda for the unpermitted release of deluge water in violation of its NPDES (National Pollutant Discharge Elimination System) permit. The settlement agreement also directs Croda to pursue a plan of sampling and remediation, pursuant to HSCA (the Delaware Hazardous Substance Cleanup Act), administered by the Division of Waste and Hazardous Substances’ Site Investigation and Restoration Section (SIRS).

Through the settlement agreement, DNREC Secretary Shawn M. Garvin issued a Notice of Penalty Assessment and Order to Croda, Inc., for the violations of Delaware air quality regulations and the company’s NPDES permit. The Secretary’s Order assesses a penalty of $246,739 to Croda, which includes $16,489 for DNREC cost recovery from responding to and investigating the incident.

In the settlement with the State of Delaware and DNREC, Croda, Inc. also has agreed to resolve all violations arising from the operation of Croda’s new EO plant as permitted by DNREC, both prior to and including the Nov. 25 incident. The settlement agreement also calls for DNREC and Croda to define further Croda’s environmental obligations for the Atlas Point facility. With Croda having accepted those obligations set forth by DNREC and agreed to necessary remedial actions required by the Department for public health and safety, the settlement with DNREC provides a path forward to resume production of ethylene oxide at the Atlas Point facility upon final approval from DNREC.

The settlement agreement and Secretary’s Order can be found on the DNREC website at https://dnrec.alpha.delaware.gov/secretarys-orders/.
