DOVER – Delaware’s Recycling Public Advisory Council (RPAC) will meet at 1 p.m. Wednesday, May 1, at DNREC’s State Street Commons Offices located at 100 W. Water Street, Dover, DE 19904. The RPAC meeting agenda can be found on the state’s Public Meeting Calendar.

The Recycling Public Advisory Council was enacted into law by Senate Bill 234 in May 2010, and charged with advising the Governor’s Office, the Department of Natural Resources and Environmental Control, and the Delaware Solid Waste Authority on all aspects of recycling, including: methodology for measuring recycling rates; development of grant criteria and selection of applications; and possible outreach activities designed to achieve higher recycling rates.

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.

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/.
A DNREC Q&A about the Nov. 25 incident and the Department’s investigation into it can be found at https://dnrec.alpha.delaware.gov/croda-questions-answers/.

DOVER – The Delaware Department of Natural Resources and Environmental Control’s Division of Air Quality and the Tank Management Section within DNREC’s Division of Waste & Hazardous Substances will hold two public workshops next month on proposed vapor emission recovery and vapor emission control at gasoline-dispensing stations and on changes to Delaware’s Underground Storage Tank (UST) Regulations as required by new federal UST regulations.

Both workshops will be held Tuesday, April 16, with one upstate workshop and one downstate, as follow:

• New Castle County: 10 a.m., at DNREC’s Lukens Drive field office, 391 Lukens Drive, New Castle, DE 19720; and
• Kent and Sussex Counties: 6:30 p.m., DNREC Auditorium, Richardson & Robbins Building, 89 Kings Highway, Dover, DE 19901.

At the workshops, staff from the Division of Air Quality and the Tank Management Section will discuss proposed regulatory changes to:

• Phase out Stage II vapor recovery systems at Delaware gasoline dispensing facilities;
• Ensure gasoline USTs remain vapor tight once Stage II systems are removed; and
• Review changes required due to promulgation of new federal UST regulations.

For more information on the workshops, please visit the Delaware Public Meeting Calendar at https://publicmeetings.delaware.gov/Meeting/62548 and https://publicmeetings.delaware.gov/Meeting/62549

Additionally, you may contact Frank Gao at in the Division of Air Quality and/or Eileen Butler in the Division of Waste & Hazardous Substances’ Tank Management Section.
