DNREC Continues Working to Assess and Clean Up Oil Spill in Delaware Bay and Southern Beaches

The Department of Natural Resources and Environmental Control continues working today to assess and clean up an oil spill that came ashore yesterday at Broadkill Beach and has now affected several more southerly coastal locations, including Beach Plum Island near Cape Henlopen, the Roosevelt Inlet and Lewes.

Some of the oil had been carried out into the Delaware Bay by last night’s high tide night and had dispersed elsewhere on the coast by noon today. DNREC and the U.S. Coast Guard were deploying environmental contractors in the Broadkill area this morning to clean up as much oil as possible before another tide carried more oil out into the bay. Cleanup operations were proceeding under the unified command between DNREC and the U.S. Coast Guard. More cleanup workers from Coast Guard contractors as well as mobilized DNREC staff were expected on the coast throughout the day.

Monday evening’s DNREC estimate of five barrels spilled may grow, but there is no further estimate on the spill’s size at this time, and the source for the oil has not been determined. The cleanup is expected to take multiple days, as globs and pools of oil must be removed from beaches manually.

DNREC Emergency Response has no reported or sighted impacts to wildlife, and also noted the vast numbers of shorebirds and horseshoe crabs that flock to the Bay coast each summer had departed on their annual migration elsewhere. DNREC Secretary Shawn Garvin asked that the public continue to report any oil sighted on- or offshore by calling the DNREC toll-free environmental hotline at 800-662-8802.

While the source of the oil spill was still unknown, DNREC provided samples of the oil today to the U.S. Coast Guard to be analyzed for a “petroleum fingerprint” that might determine where it came from. The oil was described by DNREC Emergency Response as a “heavy fuel oil” likely leaking from an operating vessel, not crude oil from the hold of a tanker.

The spill, which spanned three-quarters of a mile of upper Delaware Bay coastline last evening, was estimated this morning to have spread to up to 7 miles of beach this morning, with DNREC noting that tide had fragmented the oil from larger pooling to smaller-size speckling on the beaches. DNREC’s Emergency Response Team environmental staff gauged the size of the spill Monday after collaborating with Delaware State Police’s Aviation Unit on a reconnaissance flight over the upper Bay.

DNREC will continue to provide updates as more information becomes available.

DNREC Emergency Response Working to Control Oil Spill That Washed Ashore at Broadkill Beach

The Department of Natural Resources and Environmental Control responded this afternoon to reports of an oil spill estimated at five barrels or about 215 gallons of oil from an unknown source that washed ashore at Broadkill Beach. DNREC’s Emergency Response Team was working into the evening to survey impacts and plan a cleanup of the spill.

The spill spanned three-quarters of a mile of upper Delaware Bay coastline, depositing much of the oil that came ashore in the sand at Broadkill. DNREC’s Emergency Response environmental staff gauged the size of the spill after collaborating with Delaware State Police’s Aviation Unit on a reconnaissance flight over the upper Bay. DNREC will provide samples of the oil to the U.S. Coast Guard Tuesday to be analyzed for a “petroleum fingerprint” that might determine its source, and will work with the Coast Guard’s environmental contractor to clean up the spill.

DNREC also cautioned that, with an outgoing tide this evening, the oil is likely to migrate elsewhere along the Delaware coast tomorrow, and asked that residents of coastal communities contact DNREC’s environmental hotline (800-662-8802) to report any oil spotted either on- or offshore. DNREC Emergency Response surveyed other bay beaches this afternoon after the Broadkill spill was reported, but found no evidence that oil had come ashore elsewhere on Delaware Bay. DNREC will provide updates Tuesday morning.

Lewes WWTP, fully operational, ends discharge of partially-treated effluent into Lewes-Rehoboth Canal, Delaware Bay

DOVER – The Department of Natural Resources and Environmental Control was informed today by Tidewater Utilities, Inc. that the Lewes wastewater treatment plant was back online and had resumed normal treatment of effluent following a Dec. 18 system malfunction at the plant. Tidewater Utilities informed DNREC Saturday evening that treatment membranes contaminated during an automated backwashing process which caused the malfunction had been replaced, ending the plant’s system bypass operation that discharged partially-treated effluent for nine days into the Lewes-Rehoboth Canal and the lower Delaware Bay.

Installation today of the new and highly-effective treatment membranes by Tidewater Utilities enabled the Lewes WWTP to treat incoming flow as normal and discontinue bypass pumping. During the bypass operation, DNREC staff was onsite at the plant directing Tidewater Utilities’ sampling of the partially-treated effluent for bacteria levels and monitoring the sampling for possible health risks.

When the system malfunctioned and the bypass operation began, DNREC also ordered immediate closure of shellfish harvest areas in the lower Delaware Bay due to health concerns from partially-treated effluent. The closure of shellfish harvest areas will continue for a 21-day period from the time the bypass situation ended and Lewes wastewater treatment plant’s effluent met required discharge standards. The closure ordered by DNREC is based on US Food and Drug Administration (FDA) Guidelines under the National Shellfish Sanitation Program, and provides adequate public health protection for pathogens of concern, including viruses. The closure applies only to clams, oysters and mussels – crabs, conch and fish species are not affected.

DNREC to conduct water-quality dye test in Murderkill River and Delaware Bay to evaluate bay oyster beds

DNREC LogoDOVER – The Department of Natural Resources and Environmental Control’s Delaware Shellfish Program and Kent County Levy Court will conduct a week-long water quality study starting June 10 in the Murderkill River and Delaware Bay to evaluate the bay’s oyster beds. The study calls for applications of the red dye Rhodamine WT, which is commonly used in water quality and dispersion tests, and is not considered harmful to the public or the environment.

Weather permitting, application of the dye will be made at the Kent County Waste Water Treatment Plant near Frederica into a tributary of the Murderkill River to measure water flow and dispersion in waters where shellfish are harvested, according to DNREC’s Delaware Shellfish Program within the Division of Watershed Stewardship.

DNREC’s shellfish program utilizes a classification system that regulates the harvest of shellfish based on water quality, and which also assesses the potential risk to shellfish harvesting in the event of a wastewater spill. The goal of the red dye study is to help determine the potential impact to oyster beds in the possible event of a wastewater spill or other pollution event.

Dye applications are planned near late-evening low tide on Tuesday, June 11 and will continue until around noon the next day. As a result of the dye applications, portions of the Delaware Bay, Murderkill River and St. Jones River may turn reddish in color. The extent of water discoloration could be fairly widespread but should disperse within 48 hours.

The study – known as hydrographic dye dilution – will be conducted by DNREC in conjunction with the U.S. Food and Drug Administration (FDA) and Kent County Department of Public Works. Results will help to appropriately classify shellfish harvesting waters, assess risk, and facilitate emergency closure provisions in the event of a wastewater spill associated with extreme weather or natural disasters, such as hurricanes, nor’easters, or heavy flooding. Information collected will be used by the FDA and DNREC to evaluate potential water quality impacts and closure of shellfish growing areas in the Delaware Bay under such emergency situations.
