Governor John Carney joined state and city employees ahead of Earth Day today to remove invasive plant species and dead vegetation at Mirror Lake in Dover. The event was organized by the Delaware Department of Natural Resources and Environmental Control and the city of Dover 10 years after a successful environmental cleanup and habitat restoration at the site was undertaken by DNREC’s Watershed Assessment and Management Section and WATAR (Watershed Approach to Toxics Assessment and Restoration) team.

The 2013 cleanup used an innovative carbon technology to sequester (bind) carcinogenic polychlorinated biphenyls (PCBs) and remove them from the ecosystem in Mirror Lake. The work helped to improve the natural beauty of the lake, increase the lake’s ecological function, and made the fish there safer for human consumption.

“The Mirror Lake restoration project was an opportunity for our community to come together to tackle important environmental and water quality concerns,” said Governor Carney. “I want to thank DNREC and the city of Dover’s continued efforts to monitor and improve the health of this beautiful lake.”

“What was accomplished at Mirror Lake, though smaller in scope, was monumental as a springboard for similar projects to be conducted by our WATAR team, and others across the nation, since 2013,” said DNREC Secretary Shawn M. Garvin. “I am proud in knowing that DNREC was an early adopter of this promising remedial technology, and that we now confidently use it in other areas of the state where appropriate to help us continue making gains with water quality and in restoring fish and wildlife habitat.”

Dover Mayor Robin R. Christiansen said, “Mirror Lake speaks to Dover’s civic pride. Over the last decade it has evolved into a beautiful event venue that includes private weddings. We are thankful for the partnership with DNREC and the state of Delaware in achieving it, while being able to maintain the beauty of Mirror Lake for the neighbors and our community.”

With Mirror Lake continuing to rebound from longtime environmental ills as it empties into the St. Jones River, the wetland now plays an important role in improving water quality in the St. Jones Watershed, which spans the southern half of Kent County and Delaware’s capital city, including nearby Legislative Hall and the Tatnall Building housing the Governor’s Office, and DNREC’s downstate campus in the circa 1863 Richardson & Robbins Building which borders Mirror Lake.

The environmental cleanup at Mirror Lake in Dover garnered national acclaim through use of a first-of-its kind activated carbon product called SediMite™. The project also was featured in an article in the scholarly Journal of Environmental Engineering, co-authored by several project participants, including two DNREC scientists. Titled “Full-Scale Application of Activated Carbon to Reduce Pollutant Bioavailability in a 5-Acre Lake,” the article noted that between 2013 and 2018 the project achieved approximately 80% reduction in PCB concentrations in sediment porewater, which is the water trapped between grains of sediment in the bottom of body of water. The study also documented an approximate 70% reduction in PCB concentrations in Mirror Lake’s resident fish.

DNREC scientists are currently working with project partners to develop a plan for a comprehensive 10-year post-remediation study of Mirror Lake carbon project, to include sediment, porewater, surface water and fish tissue sample analysis. Results from the study are planned to be released concurrently with DNREC previously planned fish tissue monitoring of the entirety of the St. Jones River system in the fall of 2024.

DNREC Shuts Down Polly Drummond Yard Waste Site Following a Second Suspicious Ground Fire in a Week

The Delaware Department of Natural Resources and Environmental Control announced today that a second ground fire of unknown origin at the Polly Drummond yard waste site within a week’s time has caused DNREC to shut the northern New Castle County site until further notice.

The second fire drew local fire companies to the yard waste site this morning, forcing its immediate closure for public health and safety concerns at least until DNREC can determine the cause of the fires. DNREC also is looking into how a recurrence of these blazes might be prevented on the Delaware State Parks’ land where Polly Drummond is sited in what is essentially a residential area.

In an abundance of caution, DNREC is closing the site earlier than originally planned (January 17) until the Department can determine how to best address what’s become a real and threatening problem to keeping the yard waste site open in the future – or for reopening it in the spring.

The safety issue behind the closure was magnified today because of the site’s accepting Christmas trees for recycling into organic mulch – and the possibility that a blaze could break out again and threaten residents who had come to the site to dispose of their trees after the holidays.

DNREC has operated the Polly Drummond site since 2008 when it opened seasonally – from spring to fall, and then after the holidays – for use by the public. The Polly Drummond site was one of three “demonstration” yard waste drop-off sites in northern New Castle that the General Assembly put under DNREC’s administration after yard waste was banned from Delaware landfills in 2007. Polly Drummond is the last of those sites remaining, and the only one currently in operation.

DNREC Encourages Delawareans to Recycle Christmas Trees

Commercial Yard Waste Sites Available Statewide for Convenient Drop-off

After the holidays, the Department of Natural Resources and Environmental Control encourages Delawareans to keep their real Christmas trees out of the state’s landfills by recycling them at any of the many yard waste recycling sites located throughout the state. Tree mulch is great for helping conserve and enhance First State soil by sequestering carbon that both fertilizes the soil and helps it retain moisture.

Christmas tree recycling also saves valuable space in Delaware’s landfills. More than 176,000 tons of yard waste – which includes grass, leaves, brush, trees (Christmas trees prominent among them) and other lawn/landscape materials – was recycled in 2021. Prior to Delaware’s yard waste ban, many of these materials – considered reusable resources – were sent to landfills, taking up space rather than being handled through local markets for mulch and home composting.

Residents have the option to choose from among many sites in Delaware to drop off their Christmas tree. Some of these sites accept trees at no cost, while others charge for the service. Before residents drop off their tree, call the site in advance to see what restrictions are in place and whether there is a charge for accepting a tree to be recycled. Residents who pay for curbside collection service should call their waste hauler to see if they offer Christmas tree pickup. If pickup is unavailable from haulers, check the list of yard waste drop-off sites on the DNREC website at de.gov/yardwaste.

Trees may be accepted as soon as Dec. 26 and as late as Jan. 28, 2023, but. as each yard waste facility has its own schedule, calling ahead or checking the DNREC website is advised. Likewise, commercial haulers or landscapers should call a facility prior to delivering loads of Christmas trees to be mulched. Christmas trees are not accepted for recycling at Delaware State Parks and it is illegal to leave or dump them on dunes or beaches, or anywhere within a state park.

Whether dropping off a Christmas tree or having it collected, prepare the tree for recycling into mulch by stripping off all decorations and lights, removing any flocking (fake snow) and detaching tree stands.

Delawareans also are reminded that Sunday, Jan. 15, 2023 is the last day to drop off materials, including Christmas trees, at the Polly Drummond Hill Road yard waste site in northern New Castle County. The DNREC-administered site will close at sundown Sunday, Jan. 15 and will reopen for spring on Saturday, March 25. More information can be found at de.gov/yardwaste.

DNREC Relaunches ‘Recyclopedia’ to Improve Recycling in State

Instant Recycling Info, Waste Disposal Help at Delawareans’, Visitors’ Fingertips

In recognition of America Recycles Day on Nov. 15, the Delaware Department of Natural Resources and Environmental Control today relaunches an improved online resource to assist Delawareans and visitors alike in knowing what is acceptable for recycling in the First State. Recyclopedia, administered by the DNREC Division of Waste and Hazardous Substances, helps users determine the best way to manage waste, whether by recycling or proper disposal. Recyclopedia can be an environmental asset for residents and visitors, whether at home, work, school or while on vacation.

The web-based application at de.gov/recyclopedia offers an easy-to-navigate, pictorial guide for more than 375 common items – providing an instant response on how and where these items can be most efficiently recycled or disposed of, and directing app users to the nearest locations for either consumer action. Recyclopedia information can be retrieved by PC, tablet, cell phone, or other devices.

“The updated Recyclopedia search tool continues to leverage the latest technology enabling DNREC to help residents and Delaware visitors reduce the amount of recyclables and other waste sent to our landfills,” said DNREC Secretary Shawn M. Garvin. “One of our continuing challenges in improving the recycling rate in Delaware is the uncertainty about where, what and how to recycle. The new state-specific Recyclopedia helps us meet that challenge with better guidance for Delawareans on knowing what, how and where to recycle or to properly dispose of waste.”

Using Recyclopedia helps with citizens adhering to Delaware’s Universal Recycling Law on whether items should be placed in a curbside recycling cart, taken to a drop-off location, or put in the trash or dumpster. For example, typing “milk jugs” into the Recyclopedia product slot will get a reply that they are “Acceptable” to be put in the curbside recycling cart – Recyclopedia also informs the user to keep the cap on the jug when recycling it. Meanwhile, a search for “coffee cups” and what should be done with them in Delaware results in “Not Acceptable” for the recycling cart and that these cups should go in the trash.

Delaware’s Recyclopedia tool is dynamic and will be updated based on both user interaction and DNREC staff research. For more information, visit de.gov/recyclopedia.

Reminder: DNREC to Hold Public Hearing Oct. 26 on Proposed Biogas Facility in Southern Delaware

Public Comment to be Accepted Before, During and After Hearing on Bioenergy Devco’s Expansion Plans for Existing Composting Operation

The Delaware Department of Natural Resources and Environmental Control will hold a virtual public hearing Wednesday, Oct. 26 at 6 p.m. on the proposed expansion by Bioenergy Devco (BDC) of its existing composting facility in Seaford, Del. to transform organic waste into renewable energy. The proposed project will require multiple permits from DNREC, spanning several of the Department’s divisions, including Air Quality, Waste and Hazardous Substances, and Water. Detailed information about the project and additional related resources – including English, Spanish and Haitian Creole versions of both the DNREC public notice about the hearing and the presentation made at a DNREC virtual community workshop held Sept. 28 – can be found at de.gov/biodevco.

The public hearing will allow attendees who have pre-registered with DNREC to offer comments on Bioenergy Devco’s permit applications to be entered into the public record. All public comments made directly to DNREC – whether received verbally at the public hearing or in writing before or after the hearing – have the same weight and will be considered equally by the DNREC Secretary in making a decision on whether to grant the permits that BDC would require for proceeding with its expansion plans. It is not necessary to submit comments elsewhere – and only comments made to DNREC and entered into the public record will be considered by the Department as part of the permit decision process. Closed captioning, in languages including English and Spanish, is available as an option for comments from the community. Registration and connection information for the hearing can be found on DNREC’s Bioenergy Devco public hearing webpage.

BDC’s facility is currently permitted by DNREC to accept organic waste from approved poultry industry sources for composting. The proposed facility expansion would give BDC the capacity for receiving and processing up to 250,000 tons per year of permitted organic waste. In addition to the proposed anaerobic digestion system, the expansion plans also include construction of a wastewater pre-treatment system and a biogas upgrading plant. There is also a proposed emergency generator in the expansion plans.

Byproducts from the process would include pipeline-grade renewable natural gas (RNG) and digestate, which would be dewatered and is proposed for use in the adjacent compost facility – or to be marketed in the future as a soil amendment that can be turned into compost (and which would require a distribution and marketing permit that is not part of the current proposed project and permit applications).

Specifically, the DNREC permits BDC has applied for include:

  • A resource recovery facility permit from the DNREC Division of Waste and Hazardous Substances to construct an anaerobic digestion system, biogas upgrading plant, and compost facility, designed to process poultry industry wastes into digestate, pipeline-grade renewable natural gas (RNG), and compost. Wastes the facility will accept include poultry litter, hatchery waste, dissolved air flotation (DAF) solid cake and liquid sludge, offal, waste activated sludge, and fats, oils, and greases.
  • Two 1102 Natural Minor air pollution permits from the DNREC Division of Air Quality to construct a natural gas-fired emergency generator with a standby power rating of 1,082 kilowatts (kW) (1,451 horsepower) and four anaerobic digesters with associated biogas upgrade and air pollution control equipment. The engine used in the proposed generator set is certified to comply with, and will be required to adhere to, U.S. Environmental Protection Agency regulations.
  • Two wastewater facility construction permits from the DNREC Division of Water to construct an anaerobic digestion system and a wastewater pre-treatment system as part of the proposed resource recovery facility that processes poultry industry wastes into digestate, pipeline-grade renewable natural gas and compost. The anaerobic digestion system and wastewater pretreatment system will include three 0.208-million-gallon (MG) pretreatment tanks, and four 1.95 MG fermentation tanks, a Membrane Bioreactor System (MBR), a 0.198 MG anoxic tank, a 0.412 MG aerobic reactor, a 0.198 MG ultrafiltration feeding tank and ultrafiltration and reverse osmosis treatment systems. The treated wastewater will be pumped and hauled to the Seaford wastewater treatment and disposal facility. BDC plans for a future construction phase will eliminate the need to transport the wastewater via truck by constructing a sanitary sewer pump station and force main that will connect to a future city of Seaford force main located in front of the BDC biogas site on Seaford Road.

BDC’s permit applications and supporting materials can be found in detail on the DNREC website, de.gov/biodevco.
