NEW CASTLE — The Delaware Department of Natural Resources and Environmental Control on Thursday announced an agreement 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, DNREC announced violations at the ethylene oxide plant, including excess emissions of EO. In January, Croda restarted the facility to conduct stack testing. While testing showed that the company was back in compliance with the EO emissions, it revealed violations for nitrogen oxide at the ethanol dehydration furnace.

Further violations were detected at the catalytic combustion unit for carbon monoxide, volatile organic compounds and particulate matter.

Additionally, the agreement with DNREC addresses violations at the Atlas Point facility that Croda disclosed in its July semiannual report.

According to the agreement between Croda and DNREC, Croda will meet a schedule to complete construction to remove the hotwell as a source of emissions and reroute emissions from the EO scrubber to minimize or eliminate emissions from this source.

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.

A virtual public information session will be held by DNREC on Wednesday to answer questions and take 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 done on the DNREC website.

Croda will start no sooner than the end of next week, DNREC said.
