The Division of Air Quality will conduct a public hearing (Docket #2021-P-A-0014) on an application by Croda Inc. for a federally enforceable 7 DE Admin. Code 1102 construction permit for its facility at 315 Cherry Lane, New Castle. Public comment period closed.

Croda Inc. has requested a federally enforceable 7 DE Admin. Code 1102 construction permit [Permit: APC-2016/0068-CONSTRUCTION (Amendment 4) (NSPS) (MACT) (VOC RACT) (MNSR) (FE)] for modification of a 30,000 ton per year (TPY) ethylene oxide (EO) plant at 315 Cherry Lane, New Castle.

Modifications to the permit, in accordance with the permit application and Settlement Agreement of February 26, 2021, will include:

• Emissions from the Drying Column Hotwell will be rerouted, and no longer emitted. All references to the Hotwell will be removed from the permit.
• Emissions limits from the Vent scrubber will remained unchanged, however the percent VOC reduction shall increase from 95% to 99%, and the scrubber shall be operated within parameters set by performance testing.
• Emissions from the Ethanol Dehydration Furnace (EDF) shall be increased due to an error in the current permit as follows: CO from 0.46 lb/hr and 2.0 tpy to 1.0 lb/hr and 4.5 tpy, NO_X from 0.33 lb/hr and 1.4 tpy to 0.74 lb/hr and 3.2 tpy, SO₂ from 0.014 tpy to 0.0073 lb/hr and 0.29 tpy, VOC from 1.0 lb/hr and 4.5 tpy to 1.3 lb/hr and 5.7 tpy, and PM₁₀ from 0.04 lb/hr and 0.18 tpy to 0.093 lb/hr and 0.41 tpy.

Upon completion of construction, the Department will incorporate the operating conditions and limits of the 7 DE Admin. Code 1102 Construction permit into the facility’s existing Title V permit (Permit: AQM-003/00058) via an Administrative Amendment.
