NPDES Permits

The Department of Natural Resources and Environmental Control, Division of Water, hereby gives notice of the following proposal regarding National Pollutant Discharge Elimination System (NPDES) permits:

Croda Inc has applied for reissuance of its NPDES Permit No. DE0000621 (State Number WPCC 3127F/74) permit to discharge non-contact cooling water and storm water to the Delaware River and Magazine Ditch from its facilities located at 315 Cherry Lane, New Castle, New Castle County, Delaware.  The facility produces ethylene oxide from ethanol in a continuous process.  Side-streams include technical grade monoethylene glycol and polyglycols, and carbon dioxide.  The ethylene oxide is then used at the facility in the production of ester-type and alkoxylate-type surfactants, and blended surfactant mixtures.  An analytical lab and research & development activities which support the surfactant business are also present on the site. The permittee has identified 26 discharge points at the facility (Outfalls 001A, 001B, 003, and 1 through 23) in the permit application.  Outfalls 001A, 001B and 003 consist of non-contact cooling water and storm water.  Outfalls 1 through 23 consist of storm water only.  All of the discharges go directly or via Magazine Ditch to the Delaware River.  Process wastewater is directed to the New Castle County wastewater collection system and pretreatment program.

Based on a preliminary staff review and application of lawful standards and regulations, the Department proposes to re-issue this permit, subject to certain effluent limitations and conditions.  The proposed determinations are tentative. Persons wishing to comment upon or object to the proposed determinations are invited to submit same in writing to the Surface Water Discharges Section of the Division of Water, at the address listed below, no later than 30 days from this notice.  All comments received prior to said date will be considered in the formulation of final determinations regarding this application.

A public hearing on the above will NOT be held unless the Secretary of DNREC receives a request by 4:30 pm December 22, 2017, or if the Secretary determines that a public hearing is in the public interest.  A request for a hearing shall be in writing and shall state the nature of the issues to be raised at the hearing.  It must also show familiarity with the proposal and a reasoned statement of the permit's probable impact.

The applications, fact sheets, and permits are available for inspection or copies may be obtained by contacting:
