Success in such projects helps municipalities move closer to achieving their sustainability goals. These two Maryland projects provide value to their communities by lowering greenhouse gas emissions, providing renewable energy and environmental integrity, and creating jobs and savings for taxpayers. That’s a win for Maryland and its citizens.
Closed landfills require significant maintenance and environmental compliance expenditures for many years, more often decades. Recent changes in federal tax law under the Inflation Reduction Act have dramatically improved opportunities for public and private sector landfills to convert a liability to an income-producing asset. The Inflation Reduction Act includes provisions for a 30% investment tax credit for solar projects with other provisions that can increase this incentive to as much as 50%. There are also equivalent provisions for direct payment to non-taxpaying entities such as cities and counties. An excellent summary has been prepared by the law firm of Holland & Knight and is available here.”
Two Maryland counties are among recent SCS Engineers’ clients who are converting their idle properties into revenue-generators that serve their communities—they are installing solar farms, a growing trend on closed landfills. The Oaks Landfill in Montgomery County, MD, is one.
The Oaks Landfill Photovoltaic Array project will be a 6-megawatt (MW) system on 170 acres of the closed landfill, the largest solar project on county property. Governed through a power purchase agreement, two MWs are allocated for the County. The other four MWs are for a community solar project, with 100% of the electricity generated, provided to low and moderate-income subscribers. In total the solar energy system is expected to generate 11.4 million kilowatt hours of electricity each year – enough to power 930 homes. The solar power is expected to reduce greenhouse gas emissions as much as taking 1,740 cars off the road.
It will be one of the largest solar farms nationwide to allocate all power to disadvantaged communities. The array is on schedule to operate in 2023.
Siting solar energy installations
Ideal sites for these facilities are fairly flat (preferably less than 15% slope) with open spaces conducive to photovoltaic system installation. Favorable sites are also in close proximity to utility connection points providing developers a viable means to bring their product to market and consumers. While properties like closed landfills provide ideal locations, the projects command a robust multidisciplinary redevelopment approach. Important skills for successfully engineering and permitting these projects include landfill engineering expertise and experience with state and local permitting processes.

On December 5, 2022, the EPA released a memo providing direction under the NPDES permitting program to empower states to address known or suspected discharges of per- and polyfluoroalkyl substances (PFAS). Note that the list of Applicable Industrial Direct Discharges (page 2, paragraph A.1) includes landfills. The memo cites state programs in Michigan and North Carolina that other states may want to replicate. These approaches and others could help reduce PFAS discharges by working with industries, and the monitoring information they collect, to develop facility-specific, technology-based effluent limits.
As stated in its memo, the EPA’s goal is to align wastewater and stormwater NPDES permits and pretreatment program implementation activities with the goals in EPA’s PFAS Strategic Roadmap. The memo recommends that states use the most current sampling and analysis methods in their NPDES programs to identify known or suspected sources of PFAS and to take actions using their pretreatment and permitting authorities, such as imposing technology-based limits on sources of PFAS discharges.
The Agency hopes to obtain comprehensive information by monitoring the sources and quantities of PFAS discharges, informing other EPA efforts to address PFAS. The EPA will need this information since new technologies and treatments are in development but remain unproven to work successfully in specific industries.
Other proposed actions by the Agency include designating two PFAS as Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) hazardous substances and an order under EPA’s National PFAS Testing Strategy requiring companies to conduct PFAS testing and nationwide sampling for 29 PFAS in drinking water starting in 2023.
In a letter to Congress, SWANA and NWRA associations request that regulation under CERCLA for addressing PFAS contamination assign environmental cleanup liability to the industries that created the pollution in the first place. Both associations note that landfills and solid waste management, an essential public service, do not manufacture nor use PFAS. Therefore, the general public should not be burdened with CERCLA liability and costs associated with mitigating PFAS from groundwater, stormwater, and wastewater.

Joan the Utility Solid Waste Activities Group (USWAG) at its 9th Annual Coal Combustion Residuals (CCR) Workshop, April 17-19, at the New Orleans Marriott.
The CCR Workshop is designed to provide attendees with an understanding of the CCR Rule, a key regulatory compliance.
Abstract: CCR groundwater monitoring programs require routine detection monitoring around regulated units. The purpose of routine detection monitoring is to identify situations where groundwater quality could be impacted by contaminants mobilized from CCR. Background data are collected to characterize the statistical distributions of groundwater quality parameters in the aquifer where there is no potential impact from regulated units. During operational, closure, and post-closure care activities the same groundwater quality parameters are sampled periodically downgradient from the regulated unit and compared to these background data. Any statistically significant increases over background are investigated as a potential result of CCR leachate impacting groundwater quality.
The procedure for design and implementation of a groundwater monitoring plan foresees that all routine detection monitoring program will generate false positive results, and the EPA Unified Guidance recommends that the monitoring plan be designed to minimize the site-wide false positive rate. For CCR monitoring programs, the number of well/parameter pairs and sampling frequencies are fixed by site-specific and regulatory requirements. This leaves the CCR permittee with two focus areas to minimize the site-wide false positive rate. The first is a robust characterization of background that captures both the spatial and temporal variability at the site. The second is a complete characterization of leachate composition, including unregulated constituents, and the incorporation of correlation into the statistical comparison to background. These two focus areas can be used to minimize costly assessment and corrective action activities.
Top 3 things audience will learn:
1) Routine groundwater detection monitoring will generate false positive results.
2) There are two areas that a CCR groundwater monitoring program should focus on to minimize false positives: (1) robust characterization of background; and (2) robust characterization of leachate composition
3) Building a CCR groundwater monitoring program upon these two focus areas will ultimately help reduce costly assessment and corrective action activities resulting from false positives.
In 2014, the Environmental Protection Agency (EPA) finalized regulations addressing the disposal of coal combustion residuals (CCR) generated by electric utilities and independent power producers. The rule regulates CCR as non hazardous waste under the Resource Conservation and Recovery Act (RCRA) and establishes national minimum criteria for existing and new CCR landfills and surface impoundments, including location restrictions, design and operating criteria, groundwater monitoring and corrective action, closure and post closure care, and recordkeeping, notification and internet posting requirements. Because the rule is self implementing, it is critical that owners and operators of CCR management units and engineering consulting firms possess a thorough understanding of the rule in order to ensure consistent compliance with these new federal standards.
