DNREC Issues Corrective Action Permit to Diamond State Port Corporation for Former Chemours Edgemoor Site

The Delaware Department of Natural Resources and Environmental Control has issued a permit to the Diamond State Port Corporation (DSPC) to continue corrective actions at the former Chemours Edgemoor industrial facility in redeveloping it as a shipping container facility. The corrective actions are required under the federal Resource Conservation and Recovery Act (RCRA), with authority for implementing the act delegated to the state of Delaware.

The plant site, located at 4600 Hay Road, Edgemoor, was sold by Chemours to the DSPC in 2017. The plant was demolished by Chemours prior to the sale, and all applicable permits were transferred to the DSPC. The permit issued today by DNREC is a renewal of the prior corrective action permit. It will require asphalt capping of most of the site; contaminated materials management plan during site construction; continued implementation of the post-closure care plan for closed surface impoundments; and establishment of an environmental covenant upon remedy completion.

The site and its associated titanium dioxide pigment production facility has been regulated under the Delaware Hazardous Waste Program throughout its recent operational history. The approximately 115-acre site comprises two parcels. The larger 112-acre parcel is bounded by the Delaware River to the east; by Interstate 495 and Hay Road to the west; by Fox Point State Park to the north and by industrial sites to the south. The much smaller 3-acre parcel is located across Hay Road from the larger parcel and the former facility’s main gate.

The new permit issued to the Diamond State Port Corp. will include the requirements for providing ongoing cap maintenance, environmental monitoring and financial assurance.
The actions required in the permit issued by DNREC today provides additional assurance for protecting human health and the environment during redevelopment of the site and its proposed use as a shipping container facility.

Wilmington Charter School Team C Finishes First

Charter School of Wilmington Team C is the winner of the 2021 Delaware Envirothon, an annual environmental and natural resources education competition for high school students sponsored by the Delaware Association of Conservation Districts in partnership with the Delaware Department of Natural Resources and Environmental Control.

Charter School of Wilmington Team A finished second and Charter School of Wilmington Team B placed third out of a total of 10 teams participating in this year’s competition. In addition to the three Charter School of Wilmington teams, other teams represented Calvary Christian Academy in Dover, Middletown High School FFA, Newark Charter School, Odessa High School FFA, and the Peach Blossom 4-H team from Kent County.

Instead of an in-person competition, students competed virtually over the course of four days. Each team answered questions on topics dealing with aquatic ecology, soils/land-use, wildlife, forestry, air quality, and the current environmental issue, “Water Resources Management: Local Control and Local Solutions.” Charter School of Wilmington Team C will now represent Delaware in the virtual 2021 National Conservation Foundation Envirothon out of Lincoln, Neb., at the end of July.

Each member of the winning team earned a $500 college scholarship from the Delaware Envirothon. The winning team will also receive an award plaque for their school. The second through seventh place teams received more than $1,300 in special team awards and cash prizes. Special cash awards totaling $450 were provided to the top three Forestry teams by the Delaware Forestry Association.

Prizes in the form of gift cards and ribbons were awarded to the top seven teams. The official results are as follows:

First place: Charter School of Wilmington Team C
Second place: Charter School of Wilmington Team A
Third place: Charter School of Wilmington Team B
Fourth place: Peach Blossom 4-H Club
Fifth place: Middletown High School FFA
Sixth place: Odessa Ducks FFA
Seventh place: Newark Charter School Dino Nuggets

Since its inception, the Delaware Envirothon has awarded $6,500 in scholarships to 125 students. The competition is hosted by the Delaware Association of Conservation Districts, a voluntary, non-profit association that coordinates conservation efforts statewide to focus on natural resource issues identified by Delaware’s three local conservation districts.

DNREC Requires Croda to Take Actions Protective of Human Health and the Environment at Atlas Point Facility

The Delaware Department of Natural Resources and Environmental Control announced an agreement today 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 2020, DNREC announced violations at the ethylene oxide (EO) plant, including excess emissions of EO. In January 2021, Croda restarted the facility in order to conduct stack testing. While testing showed that the company was back in compliance with the EO emissions, it revealed violations for nitrogen oxide (NOx) at the ethanol dehydration furnace (EDF). Further violations were detected at the catalytic combustion unit (CCU) for carbon monoxide (CO), volatile organic compounds (VOCs) and particulate matter (PM). Additionally, the agreement with DNREC addresses violations at the Atlas Point facility that Croda disclosed in its July 2020 semiannual report.

According to the settlement agreement between Croda and DNREC, Croda will meet a schedule to complete construction to remove the hotwell as a source of emissions and re-route emissions from the EO scrubber to minimize or eliminate emissions from this source. Croda will apply to increase emissions at the EDF and all increases will be offset with concurrent permitted decreases at a 1:1.3 ratio. Prior to restarting the EO Plant, Croda will replace the catalyst at the CCU to improve operation of this unit and return to compliance. They will install a flue gas analyzer to measure carbon monoxide (CO) to continuously confirm catalyst performance within 30 days of the EO plant restart. Additional stack testing will be conducted within 60 days of restarting the EO plant to set operating conditions and ensure compliance with emissions limits.

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. The agreement between DNREC and Croda can be found on the DNREC website at https://dnrec.alpha.delaware.gov/secretarys-orders/enforcement/.

A virtual public information session will be held March 3 by DNREC to answer questions and take community 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 made on the DNREC website. Croda intends to restart the plant no sooner than the end of next week.

DNREC previously posted a list of questions/answers following a November 2020 public information session – they are available on the DNREC website, as is the Nov. 11, 2020 Notice of Violation issued to Croda.

Investigation of Closed Solvay Polymer Facility

DNREC Reaches Settlement with Company for Investigation, Possible Remediation at Site

The Department of Natural Resources and Environmental Control today announced a settlement with Solvay Specialty Polymers USA, LLC to address perfluoroalkyl and polyfluoroalkyl substances (PFAS) allegedly released from the company’s facility in the Marshallton area of New Castle County.

On Sept. 11, 2020 DNREC notified Solvay that it is a potentially responsible party (PRP) for the alleged PFAS release and offered the company an opportunity to enter DNREC’s Voluntary Cleanup Program (VCP) in accordance with Hazardous Substance Cleanup Act (HSCA) regulations.

Solvay is an international company that recently closed and decommissioned its facility located at 800 Greenbank Road in Marshallton. Solvay processed polytetrafluoroethylene (PTFE) by irradiating the PTFE feedstock, then milling it to a fine powder that was sold as product.

Under the terms of the settlement, Solvay must perform a comprehensive environmental investigation at the site and at potentially affected surrounding areas under the oversight of DNREC’s Division of Waste and Hazardous Substances. Based on the results of the remedial investigation, an appropriate remedy will be proposed to address any soil, sediment, surface water, and groundwater contamination which may be discovered at the site and in the surrounding areas affected by a release from the Solvay plant. At present, DNREC’s soil, sediment, and surface-water testing has not identified any known potential for health concerns for residents in the surrounding neighborhood or along Red Clay Creek.

To view the settlement, visit the DNREC website at https://dnrec.alpha.delaware.gov/secretarys-orders/enforcement/.
