SCS Engineers Landfill Methane Capture
MDE estimates that 32 active and closed MSW landfills in the state will be subject to the rule. The rule is effective June 12, 2023.

 

On June 12, 2023, the Maryland Department of the Environment (MDE) published its final regulation addressing the control of landfill gas (LFG) methane emissions from municipal solid waste (MSW) landfills in the state (promulgated under COMAR 26.11.42). Methane is a potent greenhouse gas (GHG) with a global warming potential more than 25 times greater than carbon dioxide. The rule has been several years in the making and is modeled after similar rules in California and Oregon. The rule also incorporates provisions from the EPA’s federal landfill air regulations under NSPS & EG 40 CFR 60 Subparts Cf and XXX and NESHAP CFR 63 Subpart AAAA and stands among the most stringent in the US.

The new regulation will be submitted to the EPA for approval as part of Maryland’s state plan for MSW landfills (state plan). The state plan will be equivalent to or more stringent than the EPA’s NSPS & EG 40 CFR 60 Subparts Cf and XXX and NESHAP CFR 63 Subpart AAAA and will apply to smaller and mid-sized landfills not currently subject to the EPA’s federal rules. MDE estimates that 32 active and closed MSW landfills in the state will be subject to the rule. The rule is effective June 12, 2023.

Some key provisions of the rule include:

  • The rule applies to active and closed MSW landfills that have accepted waste after 11/8/1987 and that have a design capacity greater than or equal to 2,750,000 tons and 3,260,000 cubic yards, and active and closed MSW landfills that have accepted waste after 12/31/1993 that have less than 2,750,000 tons or 3,260,000 cubic yards of waste but greater than 450,000 tons of waste in place.
  • By September 10, 2023, applicable landfills must prepare an initial waste-in-place report, calculate their methane generation rate, and submit a report to MDE.
  • Closed or inactive landfills, or closed inactive areas of an active MSW landfill, that have commenced installation of solar panels or arrays on or before 1/1/2024 are exempt from the rule if they meet certain requirements.
  • MSW landfills with a calculated methane generation rate greater than 8,548 tons per year must install a gas collection and control system (GCCS).
  • MSW landfills with a calculated methane generation rate between 732 tons per year and 8,548 tons per year can either install a GCCS or evaluate surface methane emission rate, the results of which would determine if a GCCS is required.
  • If required, landfills must operate the GCCS for a minimum of 15 years and until the point that the methane generation rate has reduced to below 732 tons per year.
  • Specific requirements for the use of control devices such as enclosed or open flares. The use of open flares is permitted only until 1/1/2025 unless MDE approves its use in writing. The rule includes minimum control requirements for devices and initial and annual source testing.
  • Evaluation of surface methane emission rates through both instantaneous (500 ppm) and integrated (25 ppm) monitoring requirements and standards.
  • Leak monitoring and standards (500 ppmv) for GCCS components that contain LFG and are under positive pressure.

This rulemaking has been several years in development and is consistent with Maryland’s GHG Reduction Act of 2009 and the recent Climate Solutions Now Act of 2022 that requires Maryland to become “net zero” for GHG emissions by 2045, with an interim goal of achieving 60% GHG reductions by 2031 (over 2006 levels). MDE estimates this rule will achieve a 25-50% reduction in GHG emissions from affected landfills.

Dr. Hostetler will present “A Computational Modeling Approach to Critical Pressure Calculations for Class VI Area of Review Delineation” [Thursday, September 14, 10:30 – Noon, Session Class VI UIC] at the Groundwater Protection Council 2023 Annual Forum in Tampa.

Presentation Category:  Carbon Capture and Underground Storage

Subsurface pressure increases as supercritical carbon dioxide is injected into a deep saline reservoir beneath a confining zone.  If the pressure buildup is great enough, brine could be lifted upward from the injection zone through an inadequately plugged or abandoned well that penetrates the confining zone.  This could result in the endangerment of an underground source of drinking water (USDW).  A Class VI Injection Permit requires a delineation of the Area of Review (AoR). The AoR is the superposition of the area of the buoyant supercritical plume itself, together with the area over which the pressure front is large enough to potentially endanger a USDW through some conduit.  The USEPA Class VI Guidance offers several approaches to calculating critical pressure.  Some of these methods are based on concepts of changes in potential energy in artificial penetration and are very easy to implement.  Unfortunately, they are simplified models and are also very conservative.  The USEPA Guidance also allows for the computation of the critical pressure by computational modeling.  We present a computational modeling approach that is more mechanistic, explicitly addresses uncertainty, can be updated as additional testing and monitoring data become available, and provides a more authentic representation of the critical pressure and hence, the AoR.

SCS Engineers Due Diligence
Depending on the former uses, the number of RECs, and ESA results, some sites are more likely to feel the impact on the potential value of a property.

 

The Environmental Protection Agency (EPA) is proposing to designate perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), including their salts and structural isomers, as hazardous substances. The proposed rule published in the Federal Register designates two per- and polyfluoroalkyl substances (collectively, PFAS) constituents as CERCLA Hazardous Substances. While this is a small subset of PFAS constituents, PFOA and PFOS are reportedly the most commonly used and likely to be detectable. Additional PFAS compounds are certainly on the horizon for consideration by EPA and, in fact, an Advance Notice of Proposed Rulemaking was issued by EPA in April of 2023 to seek input for seven additional compounds for hazardous substance designation.

 

What Could This Mean For Property Transactions and Real Estate Development?

When the CERCLA hazardous substance rule becomes final (anticipated in 2023 or 2024), it will be mandatory to consider these PFAS constituents when performing Phase I Environmental Site Assessments (ESAs) to identify Recognized Environmental Conditions (RECs) in connection with a property. Because of the ubiquitous use of PFAS, often called “forever chemicals,” in residential, commercial, and industrial products, some Environmental Professionals are concerned that PFAS-related RECs will be commonplace.

In their recent paper, “How Will EPA’S Proposed CERCLA Hazardous Substance Designation of PFOA and PFOS Impact the Environmental Due Diligence Practice?” Jeff Marshall, PE, and Mike Miller, CHMM, discuss the anticipated impacts of the PFAS rule on environmental due diligence. Depending on the former uses, the number of RECs, and ESA results, some sites are more likely to feel the impact on the potential value of a property.

As our PFAS knowledge continues to evolve, so will applying this knowledge to the environmental due diligence practice and, ultimately, real estate conditions. Read the technical paper to understand the terminology and types of properties more likely at risk.

Charm Industrial’s (Charm) $53M deal with Frontier to voluntarily sequester bio-oil underground is an example of early market leadership for alternative subsurface deployment methods in the negative carbon emissions market.  SCS was instrumental in developing the pilot programs, initial testing, and regulatory approvals allowing Charm to scale up its processes and deliver on this commitment.

This deal will remove 112,000 tons of carbon dioxide by 2030. Charm’s method involves converting excess organic material, like corn stover, into bio-oil and putting that oil into abandoned oil wells.

Carbon capture has been a focus for Frontier for some time now. Prior to this announcement, they partnered with early-stage startups to remove 9,000 tons of carbon.  This landmark deal is a continuation of Frontier’s efforts to spark growth and bring attention to the industry and is one of the largest legally binding agreements to date.  SCS is thrilled for Charm and Frontier and this huge step forward. See the recent CNBC news article below for more information on this deal and its carbon offset impact.
