Effective Monday, August 14, 2023, motorists can expect inspection and maintenance changes that will impact the registration of their vehicles, especially in Sussex County.

On January 11, 2023, the Delaware Department of Natural Resources and Environmental Control (DNREC) revised the Motor Vehicle Inspection and Maintenance regulations in Delaware in an attempt to reduce emissions and improve air quality.

The amendments to Regulation 1126 and Regulation 1131 include:

• OBD-II* testing for vehicles model year 1996 to 2007 with a MGVWR** up to, 8,500 lbs. in all three counties including Sussex County.
• OBD-II testing for vehicles model year 2008 and newer with a MGVWR up to 14,000 lbs. in all three counties including Sussex County.
• Vehicles model year 1995 and older will require a curb idle and gas cap test in all three counties including Sussex County.
• Stricter penalties for removing or modifying the emission control system in a vehicle in all three counties.

Currently, there are more than one million vehicles registered in the State of Delaware, with 323,576 vehicles registered in Sussex County. Residents, especially in Sussex County, are urged to give themselves extra time for registration renewal, particularly if they believe their vehicle will need repair under the new regulations. Motorists can renew their registration up to 90 days prior to its expiration.

The Delaware Department of Natural Resources and Environmental Control (DNREC) announced Friday that it has authorized the ethylene oxide plant at the Croda Atlas Point facility near New Castle to restart solely for the purpose of conducting an emissions test, then will shut down and await a department decision on a path forward. The EO plant had a failed emissions test, known as a “stack test” in September that led to a recently issued Notice of Violation (NOV) for air emission and equipment violations associated.

The EO plant will start up the first week of January and the test will be conducted the second week of January, as the plant must be fully operational for the test. Operation for the purpose of the testing will not include the hotwell or use of the unpermitted emission source. During the operation, the company must monitor water circulation and pressure through the scrubber. The tanks will also be monitored for pressure and temperature. These operational parameters will be reported to DNREC. During the test, DNREC staff will be on site and ethylene oxide levels and scrubber performance will be known in real time. The operational data will also be collected.

The EO plant will shut down following the completion of the testing. DNREC continues to work from its regulatory purview to determine the path forward for Croda to resume operations at the EO plant.

A public information session was held virtually with about 75 participants on November 19 to answer questions and take comments about Croda’s operations and about the NOV. DNREC on Friday released a list of questions that came up at the session with responses for the community, available at https://dnrec.alpha.delaware.gov/croda-atlas-point/.
