SCS Engineers met a tight, non-negotiable regulatory deadline to get the new plant on-line while meeting non-toxic effluent standards.
Everyone enjoys before and after pictures; just look at the results New Hanover County’s program is producing. This and other County programs are helping this North Carolina county reduce reliance on landfill disposal while creating a comprehensive and sustainable solid waste management system that is protective of the environment.
In 2016 a new wastewater treatment plant was commissioned at the New Hanover County Landfill. The new facility processes approximately 65,000 gallons per day (GPD) of leachate using state-of-the-art ultrafiltration (UF) and reverse osmosis (RO) technologies to meet or exceed federal and state treatment standards.
The raw leachate is pre-treated in an existing aerobic lagoon followed by a sequencing batch reactor (SBR) to reduce organic constituents. The pretreated effluent then flows into the membrane system. Using state-of-the-art membrane filtration technology, including ultrafiltration (UF) pictured at lower left, and a reverse osmosis (RO) system, pictured lower right, to produce crystal clear, effluent discharged to an upper tributary of the Cape Fear River.
The new facility can process 75,000 GPD and the Wastewater treated through the new system meets state Drinking Water standards for quality.
Tough surface water discharge standards and predictable performance in cold weather drove the design to use UF/RO systems. The results are impressive; metals including arsenic are BDL, ammonia <0.2 ppm, and TSS < 2 ppm. The system produces approximately 13,000 GPD of RO concentrate that is pumped to the working face and safely disposed of in the landfill. The County has certified operators that have played a big role in getting the plant shaken down and running smoothly.
“New Hanover County is an industry leader in adopting proven technologies to better manage solid waste, and protect the environment. This kind of planning and approach can benefit many other public works departments,” stated Bruce Clark, PE, BCES, LEED AP®, and SCS Engineers National Expert on Waste Conversion.
As Joe Suleyman, the County’s Environmental Management Director put it, “Let’s face it – people move to New Hanover County because they love to be in, on, or near the water. Our technical staff is composed of very talented folks who have environmental science and biology backgrounds. They believe in what they’re doing to help protect our delicate coastal environment, and this state-of-the-art system is a huge stride towards meeting our own expectations and those of the citizens we serve.”

Historic fill is common on properties that were once rural and have become prime redevelopment sites as communities expanded. The fill may include contaminated materials like foundry sand, ash, demo and construction debris, and even municipal waste. In the past, these materials were used to fill wetlands or change the grade of the property before initial development. Today regulations have evolved, and state agencies require property owners to manage these materials appropriately during redevelopment. Also, particular types of historic fill are often not robust enough to structurally support your new building.
There are many different kinds of fill materials – each with different physical properties and different potential contaminants. Knowing what is on your property before you start designing the site layout, and certainly, before you start digging, will help you plan your project to save time and money, and to receive state agency approval.
Before You Buy
The more you know about the property and the earlier you know it, the better prepared you will be to make decisions about how best to protect yourself from potential environmental liabilities and prepare for the environmental and geotechnical issues that historic fill can cause. Since every property is unique, the first thing you need to do is gain a thorough understanding of the property’s history and past use. Invest in a comprehensive Phase 1 Environmental Site Assessment (ESA). Consider it a starting point for clues about the possible types and amounts of historic fill which may be present on the property.
If the results of the Phase 1 ESA warrant it, conduct a Phase 2 ESA and geotechnical study to collect soil, fill, groundwater, and soil vapor samples. The Phase 2 ESA and geotechnical studies will help you understand if fill and contaminants are present and the best options for addressing them during the development planning stage.
Historic fill on a property is no longer the impediment to development that it once was. Take these steps to get ahead of potentially contaminated historic fill, and keep your project on time and budget.
By testing early, performing a proper geotechnical evaluation, and incorporating design adaptations where needed, you can successfully develop projects with historic fill within your schedule and without breaking your budget.

Over years of working on operations and maintenance of landfill gas collection and control systems and leachate management systems, SCS found that too many times data is collected and no one has the time to review and analyze it for improved decision-making.
As an industry-wide issue, SCS developed systems to streamline the process using technology and our field expertise to help perform routine and sometimes complex data analysis and to automatically push reports and alerts to operators, engineers, and project managers.
The improvements are dramatic; by removing human error from reviewing pages of data we now focus our time and energy on what really matters, using what the data tells us to make informed decisions. Let’s put the technology into the context of everyday operations – identify, troubleshoot, and solve landfill gas and leachate challenges.
This SCS paper illustrates several sites using integrated systems for data collection and analysis and how they are used to identify, troubleshoot, and solve real problems in an effective and efficient manner.

By October 17, 2016, coal combustion residual (CCR) landfills subject to the Environmental Protection Agency’s (EPA) CCR regulations published at 40 CFR 257, Subpart D, also known as the Federal CCR Rule, were required to prepare a Run-on and Run-off Control System Plan. Your plan documents how you have designed and constructed your landfill to prevent storm water from running onto or off the active landfill. But, what’s next?
Have you addressed run-on and run-off control system operation and maintenance?
Spring is a great time to review your storm water control plans and, more importantly, your storm water controls. The snow is gone now and spring rains are on their way, so knowing that your storm water controls are working and water is going where you intend it to go should be part of your spring inspection routine. Don’t want to waste money managing clean storm water with your leachate management system, or put your facility at risk by allowing unintended runoff from the landfill. A few basic inspection tasks will help ensure you don’t.
A spring run-on and run-off control system inspection should include the following:
Don’t let spring rains catch you off guard. SCS Engineers can help you assess the effectiveness of your run-on and run-off control systems. For help conducting storm water inspections as well as studies to review leachate, contact water, and storm water minimization and reuse opportunities, or for questions about run-on and run-off control system inspections or more information about minimization and reuse studies, please contact:

Did you know Wisconsin has more than 80,000 properties with a history of contamination or remediation? What if you could transform even the most challenged property into a center of economic prosperity? You can with three well-established reimbursement programs.
PECFA
The Petroleum Environmental Cleanup Fund Award (PECFA) program is administered by the Wisconsin Department of Natural Resources (WDNR) and is funded by a petroleum inspection fee. PECFA has provided funding for investigation and cleanup of petroleum contamination from petroleum product storage systems at tens of thousands of properties in Wisconsin since it started in the 1980s.
The WDNR estimates there are more than 100 eligible, enrolled sites that have stalled and are at risk of not being reimbursed for eligible costs. If you have an open PECFA project, and especially if you have a stalled PECFA project, act now or you may lose your funding. The program is closed to new applicants and will sunset on June 30, 2020. No claims will be accepted after this date.
ACCP
The Agricultural Chemical Cleanup Program (ACCP) provides financial assistance for agricultural chemical investigations and cleanups to property owners and people who have caused or own/control spilled agricultural chemical(s). Companies that apply for ACCP funds include ag-chem cooperatives, ag-chem transport companies, farm enterprises, and other ag-chem suppliers and users. Cleanup costs can be reimbursed at 75% of eligible costs between the deductible and the $400,000 discharge site maximum with a proposed increase to $600,000 per site maximum in the Governor’s 2017 budget. To qualify, you typically need a site investigation and remediation by a professional engineer and hydrogeologist.
DERF
The Dry Cleaner Environmental Response Fund (DERF) provides financial protection for Wisconsin dry cleaner owners if contamination occurred from their operations. The program began in 1997 and is funded by fees on dry-cleaning receipts and the solvents used in the dry-cleaning process. The maximum award is $500,000 per facility. DERF is closed to new applicants; however, eligible owners can still receive reimbursements for site investigation and remediation activities. The estimated reimbursement time is two to three years from claim submittal.
Thousands of Wisconsin property owners have used PECFA, ACCP, and DERF to address contamination on their properties. Contact SCS Engineers to learn how you can use these programs to ease your redevelopment costs.

There is no single best approach to financing fleet replacement costs. With the financial challenges facing local governments today in providing cost-effective and timely solid waste management services, evaluation of these various approaches should be made focusing on ways to minimize costs while providing value-added services to the public.
Marc Rogoff discusses a number of alternative vehicle/equipment purchasing programs, which are being used by solid waste agencies to preserve cash. Each of the financing methods described has its own particular advantages and disadvantages, which can be influenced by local municipal circumstances.
