Protect Our Environment and Controlling Climate Change

SCS Engineers Environmental Consulting and ContractingThe ISWA World Congress attracted 1,200 participants this year despite the pandemic and received major coverage in the news while heating up social media channels. The Business Times Singapore published an 8-page supplement and a feature article about James Law and his views as Chair of the ISWA Landfill Group on what we, as individuals and communities, can do to protect our environment.

Featured speakers included Alex Stege and his Solid Waste Emissions Estimation Tool (SWEET) used in a project in Tyre Caza, Lebanon. SWEET allows solid waste planners to compare emissions from implementing different programs and quantify the effectiveness of available waste management options in reducing emissions of GHGs and air pollutants.

Alex presented during the Waste Management In An Era Of New Energy track. His discussion covered Evaluating the Energy Potential of 16 Landfill Gas to Energy Projects in China to be financed by the International Finance Corporation (IFC). There are 24 landfill gas-to-energy projects in China, including ten sites already under operation. In 2021, IFC hired SCS Engineers to evaluate the NCWI estimates and prepare a report providing independent LFG generation and recovery projections for the 16 landfills. The project developer (NCWI) provided IFC with waste data and LFG generation and recovery projections for 16 of their project site landfills from the report indicating a sufficient supply of recoverable LFG to support their planned facility capacities.

SCS Engineers was asked to comment to the NWRA and SWANA industry groups in their October 6 letter to U.S. Environmental Protection Agency on the proposed new EPA rule changes for GHG reporting. SCS’s deep expertise and knowledge of GHG monitoring and reporting, especially GHG rule k values, help inform the revisions and determinations for data elements under the Greenhouse Gas Reporting Rule.

It is wonderful to see ISWA and SWANA in leadership roles to help us meet a global challenge!

Article published in the January 2020 edition of Waste Advantage Magazine.

At the Federal level, GHG emission reporting has become part of the standard regulatory requirements; however, on the west coast, GHG programs continue to develop and evolve from reporting to reduction programs beyond federal requirements. Solid waste facilities can be impacted by all of these reporting mechanisms directly as a landfill located in the state in question, opting in for C&T as part of the LCFS in California, or in limbo, as the courts work out the legality of Washington’s Clean Air Act. More stringent federal GHG requirements are unlikely with the current administration, however, that could change with the 2020 election. In general, GHG rules and legislation keep developing and updating to account for and reduce GHG emissions.

Our latest SCS Technical Bulletin summarizes the EPA federal mandatory greenhouse gas (GHG) reporting program (GHGRP) into two pages of the most vital information. The new reporting requirements for Subparts HH and A discussed in our bulletin are effective January 1, 2017.

2016 GHG emissions reports due on March 31, 2017, must be completed in accordance with the updated Rule.


Remaining updates will be phased in from 2017 to 2019. These updates include, but are not limited to, revisions to the reporting regulation for all reporters including Subpart A Administrative Requirements, Subpart C Stationary Combustion Sources, and Subpart HH Municipal Solid Waste Landfills the three most common reporting sectors for MSW landfills. SCS Engineers will continue to post timely information, resources, and presentations to keep you well informed.
