A. INTRODUCTION
The Northeast Maryland Waste Disposal Authority (“Authority”) is a multi-county agency created by the
State of Maryland to assist participating member jurisdictions (“Member Jurisdictions”) with solid waste
management systems. Member Jurisdictions include Baltimore City and Anne Arundel, Baltimore, Carroll,
Frederick, Harford, Howard, and Montgomery Counties. Maryland Environmental Service, an
instrumentality of the State of Maryland, is an ex-officio member. More information on the Authority can
be found at: www.nmwda.org
The Authority is issuing a Design, Build and Operate Request for Expressions of Interest (“REOI”) to assist
its Member Jurisdictions with Beneficial Use of Landfill Gas for mainly Small, Closed and/or Rural Landfills:
Utilizing Mobile Turbines or Engines, Compressed Natural Gas/Renewable Natural Gas Systems and/or
Direct Landfill Gas to Energy Power Purchase Services (e.g., Power Purchase Agreements or “PPAs”)
(“Services”). These Services would cover the responsibilities for managing any landfill gas (“LFG”) after it
runs through the Member Jurisdiction blower system (for existing flares onsite), for the landfills with flares
and blower systems. Member Jurisdiction existing landfill gas operation, monitoring and maintenance
staff/contractors would be expected to perform their existing functions, as is, for the existing landfill gas
collection system and for all gas before it reaches the blower onsite, as applicable. The Authority is seeking
interest in these Services for landfills within the Member Jurisdiction footprint. This REOI is being issued
in order to help gain an understanding of companies or other entities (“Contractors”) that would be
interested in performing these Services. If the Authority determines that there is sufficient interest and
ability to provide these Services, the Authority may issue a Request for Proposals (“RFP”) to provide that
Service or negotiate a contract directly with an interested Contractor that has responded to this REOI.
This REOI is not intended to provide sufficient detail in order to select a Contractor for the Service. The
Authority and its Member Jurisdictions are open to receiving proposed amendments as part of the
Contractor’s response to any/all of the sections provided in this REOI, including Section C Current Small,
Closed and/or Rural Landfills, Equipment Needed and Operational Requirements of Service. Any specific
requirements listed herein are open to consideration and amendment, in order to create the best working
model and Service for all entities involved. As part of its response, the Contractor must describe how they
would best manage this type of operation and detail the logistics required for each Member Jurisdiction.
Responses to the REOI are due by Thursday, January 25, 2024, at 4:00 pm (local time). Submission
requirements are shown below in Section D. The Authority will make a determination as to whether to
progress to a RFP process, enter into competitive negotiations with one or more Contractors, or to
discontinue with the REOI. All Contractors that respond to the REOI will be notified of the Authority’s
determination in writing.

B. THE OPPORTUNITY
The Authority’s Member Jurisdictions continue to pursue 1) greater macro scale landfill greenhouse gas
(methane) and other emission reduction efforts, 2) higher destruction capability of particulate matter on
a micro (local) scale by implementing systems with higher burning temperatures, allowing for less
nonmethane organic compounds (“NMOC's”), volatile organic compounds (“VOCs”), nitrogen oxides
(“NOx”) and hydrogen sulfide (“H2S”) to be emitted, (more specifically, “many of the technologies and
practices that reduce methane emissions also reduce associated emissions of volatile organic compounds
(VOCs), odors and other local air pollutants…Burning LFG to produce electricity destroys most of the non-
methane organic compounds (including hazardous air pollutants and VOCs) that are present at low
concentrations in uncontrolled LFG, which reduces possible health risks from these compounds. In
addition, gas collection can improve safety by reducing explosion hazards from gas accumulation in
structures on or near the landfill,1”) and 3) related beneficial community projects (such as recycling and
trash collection, annual, bi-annual or quarterly, etc. litter/illegal dumping cleanups and related anti-
litter/recycling signage placement at those landfills transformed into public trails/parks), as well as
additional infrastructure services/renewable energy projects, such as solar installations, on both active
and closed landfills. Some Authority Member Jurisdictions have existing landfill gas to energy facility
services (“LFGTE”), with some operated by the private sector or Member Jurisdiction staff. The Authority
would like to provide more Service options to its Member Jurisdictions by providing the ability to initiate,
expand and supplement existing beneficial use of landfill gas Services and potentially improve on the
landfill sites, for the public good, by sponsoring optional site improvement services, as described above.
If Designated Landfills (as defined below) or other identified landfills are later determined to no longer be
suitable candidates for beneficial reuse of landfill gas, due to low gas levels, poor gas quality, etc., the
awarded Contractor is allowed to pursue the option, including feasibility studies, of additional renewable
energy projects at the Designated Landfills or other identified landfills, such as solar installations, as
referenced above, if approved in writing by the Member Jurisdiction.
Services can include, but are not limited to, the following concepts in order to streamline implementation
timelines (including combined projects of different types of Services and Contractors): direct power
purchase agreements, self-sustaining modular designed, easily deployable micro grids using engines,
turbines and/or renewable natural gas (“RNG”)/compressed natural gas (“CNG”) applications powering
electric/RNG vehicle charging/fueling stations, facility heat and power onsite, leachate and water
treatment onsite, decentralized data processing using modular data centers (inside a C Container, shed or
similar small structure) that can continue to act as scalable systems for future growth (e.g., cryptocurrency
mining, graphics rendering, AI modeling, other data processing centers, etc.), including any potential
opportunities as an interconnect for grid connections nearby and/or related to E-RINs and/or
carbon/greenhouse gas credits. For PPA projects, the Authority may request the per therm or per kWh
cost from the Contractor and may request a fixed cost (as there may be different starting rates if there is
a fixed rate versus an escalating rate over the term of the Master Service Agreement (defined below)).
