DNREC Issues Croda NOV for Air Quality Permit Violations

Information Session on Path Forward for EO Plant Set for Thursday, Nov. 19

The Delaware Department of Natural Resources and Environmental Control (DNREC) has issued a Notice of Violation (NOV) to Croda, Inc. for air emission and equipment violations associated with the operation of the ethylene oxide (EO) plant at Croda’s Cherry Lane Facility near New Castle.

The violations include: connecting and routing an unpermitted source into an air pollution control device (scrubber); exceeding the annual emission limit for ethylene oxide at the scrubber; failure to meet the volatile organic compound (VOC) removal efficiency at the scrubber; and operation of an unpermitted source of ethylene oxide at the hotwell, which collects and condenses vapors from the purification and vacuum distillation of crude ethylene glycol. The violation notice can be found at http://www.dnrec.delaware.gov/Admin/Documents/croda-nov-20201111.pdf.

The violations at the EO plant outlined in the notice were discovered through a source testing event conducted Sept. 17 by the company and observed by DNREC staff. Croda submitted results of the testing to the Department in a report dated Oct. 5. Following receipt of the report, DNREC has been working to accurately quantify Croda’s emissions that resulted in the NOV issued by DNREC, as compared to the emissions Croda is allowed under conditions of its air permit for the EO plant. For example, while some fugitive emissions are associated with the hotwell, ethylene oxide was detected there during the stack test, and is not permitted at this location.

The ethylene oxide plant has not operated since the date of the test.

An NOV is the first step in a process that can lead to DNREC taking further enforcement actions. DNREC is currently working from its regulatory purview to determine the path forward for Croda’s resuming operations at the EO plant.

DNREC will hold a virtual information session at 6 p.m., Thursday, Nov. 19 to describe the violations and answer questions from the community nearby to the Croda facility. The public may join the video meeting via WebEx at https://stateofdelaware.webex.com/stateofdelaware/onstage/g.php?MTID=e4c89abf0bc79ce0f842c2b6e9d0eb72b with event number 173 655 4144 and password CrodaInfoSession, or to join by audio conference only, by calling 408-418-9388.

DNREC announces that Croda, Inc. can resume ethylene oxide production at company’s Atlas Point facility

Approval granted for operation of Croda’s EO plant after company fulfills Delaware accidental release prevention requirements

DOVER – Department of Natural Resources and Environmental Control Secretary Shawn M. Garvin announced today that the Department has granted approval to Croda, Inc. to resume ethylene oxide (EO) production at the company’s Atlas Point facility. Croda received DNREC approval by fulfilling its obligations to improve safety at the facility through actions required by DNREC’s accidental release program. DNREC issued its requirements after investigating the Nov. 25, 2018 accidental release of EO, the volatile chemical substance used in the manufacturing of Croda’s products.

DNREC Secretary Garvin ordered Croda to complete seven accidental release prevention action requirements before the Department would approve the resumption of EO production at Croda’s new ethylene oxide plant. At DNREC’s direction, Croda completed an internal incident investigation report; a focused process hazard analysis of all EO release points; a fire water system hazard analysis; fire water system procedures training; fire department manifold connection to Croda’s fire water system supply tank; employee training for EO plant operation and emergency procedures; and a safety validation process – also known internally by Croda as the pre-startup safety review.

In addition to DNREC’s requirements, Croda installed automated purge and isolation valves, 26 additional fixed ethylene oxide gas detectors and eight additional closed circuit TV cameras, as well as upgraded its vapor suppression capabilities.

After coordination with DNREC and the New Castle County Office of Emergency Management, Croda also decided to install an emergency siren system to be used in conjunction with several other notification systems for alerting the public in the event of an accidental release by the facility. The system will be installed on or about Jan. 31, 2020.

Within a month of the Nov. 25, 2018 incident, DNREC, along with numerous state and local government agencies and Croda officials, held a public information meeting to review the incident and governmental agencies’ response. Other agencies included Delaware’s Department of Homeland Security, Delaware Emergency Management Agency (DEMA), Division of Public Health, State Emergency Response Commission (SERC), and the New Castle County Department of Public Safety and Local Emergency Planning Committee (LEPC). DNREC also held a second public meeting in August with Croda to update the surrounding community on the required accidental release prevention actions and obtain additional community input.

After Croda established that it had met all of DNREC’s requirements, including resulting upgrades and safety improvements for both Croda employees and the community, Secretary Garvin announced today that the company could begin operating the ethylene oxide plant again at the Atlas Point facility.

DNREC determines deluge water used to contain Croda, Inc.’s 2018 ethylene oxide release did not impact the environment

DOVER – The Department of Natural Resources and Environmental Control (DNREC) has concluded that there was no increased risk to human health or safety from deluge water used to contain the Nov. 25, 2018 ethylene oxide (EO) release at Croda’s Atlas Point facility. DNREC’s conclusion was made from a soil and groundwater sampling report required of Croda by the Department as part of a settlement agreement with DNREC in the aftermath of the EO incident.

The full report, prepared by an environmental consultant on Croda’s behalf and reviewed by DNREC’s Site Investigation & Restoration Section, can be found on the DNREC website. The DNREC-Croda settlement agreement requiring the report from Croda assessed a penalty of $230,000 to Croda for air, hazardous waste and water quality violations stemming from the EO incident, and additional steps to be completed by Croda before the EO plant can resume operations.

Data in the soil and groundwater report was based on the amount of deluge water that exceeded a containment sump at Croda’s facility in New Castle. Terms of the settlement agreement required soil and groundwater sampling by Croda to determine if EO-contaminated deluge water had impacted the area west of Croda’s EO production unit. EO was not detected in any of the soil or groundwater samples from Croda, according to the report.

Another compound associated with Croda’s operations, 1,4-dioxane, considered a contaminant, was detected in two soil samples, as well as the groundwater sample from the company. For the site’s intended manufacturing use, the reported concentrations of 1,4-dioxane in the groundwater samples do not pose an unacceptable risk to health and safety. The reported concentrations of 1,4-dioxane, the locations of detections noted during sampling, and past detections of 1,4-dioxane by DNREC at the site led the Department to conclude that there is a very low probability that last year’s EO release was the source of the 1,4-dioxane concentrations sampled. Based on the levels and location, no further action is required to address this portion of the site.

A DNREC letter to Croda reiterated that the Nov. 25, 2018 EO release does not change remedial actions already required by DNREC in addressing site contamination at the Atlas Point facility and that are ongoing as directed by the Department.
