Do you represent one of the 10,000 companies in the U.S. doing business in California that will be affected by sweeping new climate-related disclosure requirements recently signed into law?
California requirements for public disclosures cover corporate climate-related financial risk (SB 261) and corporate GHG emissions/targets (SB 253). While these state climate disclosure laws are subject to court challenges, they are still in effect, so companies are collecting data now.
The requirements will impact public and private companies in the U.S. doing business in California, including companies headquartered outside of the state.
If you reply yes to the questions below, you must report your company’s Climate Disclosure starting in 2026.
This live educational webinar will highlight these new disclosure requirements for climate disclosures, apply the standards, and provide the related assurance requirements for each. This one-hour webinar is free and relevant to all industries. Meet our panelists.
Our panelists will explain the carbon accounting expectations, materiality considerations, and what to do now to prepare. We’ll provide an update on the net impact of timely court decisions affecting California requirements, as well as the impact of similar disclosure requirements under the CSRD rules of the European Union.
Start or refine your roadmap for the journey to mandatory reporting and reflect upon the relationship of these disclosures to U.S. firms remaining globally competitive.
This live webinar will run longer than an hour to answer questions posed by those attending. You and your company have the option of asking questions anonymously to protect your privacy. If you must leave early, we will send those registered a recording. SCS Engineers provides educational webinars without a sales pitch and never shares your contact information.

Addition of PFAS with final toxicity values
On January 3, the U.S. Environmental Protection Agency announced the automatic addition of nine per- and polyfluoroalkyl substances to the list of chemicals covered by the Toxics Release Inventory. The nine PFAS were automatically added for reporting due to EPA having finalized a toxicity value during 2024, and whose identity is not claimed as confidential business information. These nine PFAS are:
Addition of PFAS no longer claimed as confidential business information
Under NDAA section 7321(e), EPA must review CBI claims before adding a PFAS to the TRI list if the chemical identity is subject to a claim of protection from disclosure under 5 U.S.C. 552(a). EPA previously identified Acetic acid, [(γ-ω-perfluoro-C8-10-alkyl)thio] derivs., Bu esters for addition to the TRI list based on the NDAA’s provision to include specific PFAS upon the NDAA’s enactment. Due to CBI claims related to its identity, this PFAS was not added to the TRI list at that time. The identity of this chemical was subsequently declassified in an update to the Toxic Substances Control Act Inventory in May 2024. Because its identity is no longer confidential, it was added to the TRI list.
These nine newly added PFAS, along with the previous 196 TRI-listed PFAS, are also subject to EPA’s action in October 2023 to classify all PFAS subject to TRI reporting as chemicals of special concern. Among other impacts, this removes the use of a reporting exemption that allowed facilities to avoid reporting information on PFAS when those chemicals were used in small concentrations.

EPA updated its Compliance and Emissions Data Reporting Interface (CEDRI) for the electronic reporting of air emissions under the NESHAP related to MSW landfills. Three new reporting templates were added on October 15, 2024, each linked to its corresponding Excel spreadsheet template. These include the
The Semi-Annual report is the most significant because MSW landfills have 90 days to begin using the Excel template. Reports due January 13, 2025, or any time after that must include this electronic filing.
EPA’s color-coded template provides a bit of instruction.
The gray tab (Company Information) contains general information likely to be unchanged from report to report. After completing the gray tab, you may save the workbook as a site-specific template to use in subsequent reports to limit subsequent data entry.
Complete the green tabs (Certification, CMS Info, Description of Changes, Exceedances, and Number of Exceedances) as appropriate to complete the semi-annual report.
Complete the blue tabs (Deviation Detail, Deviation Summary, CMS Detail, and CMS Summary) if deviations or CMS out-of-control periods or downtime periods occur according to §63.10(e) and as defined in §63.1990.
The orange tabs (Well Expansion, Operational Statements, Site Specific Treatment, Enhanced Monitoring, Bypass CDT Not Operating, and Corrective Action Analysis) cover information required by the semi-annual report requirements of §63.1981(h); be sure to complete the requisite tabs.
Professionals at SCS Engineers will post more guidance but plan to continue preparing our clients’ semi-annual reports as we do now, and completing and submitting this spreadsheet. Please work with your air emissions specialist or project manager, or contact us for support.

This Air & Waste Management Association specialty conference is the perfect event to provide an important basis for future development and advancements in the air quality modeling field. It will also provide in-person opportunities for stakeholders and regulators to discuss the challenges and techniques to model ever-tightening air quality standards.
The technical program will include an opening plenary session devoted to invited presentations by EPA’s Office Air Quality Planning and Standards (OAQPS) Air Quality Modeling Group (AQMG). Multiple sessions will cover key modeling topics, and the popular Town Hall Meeting will include an interactive Q&A format with high-level regulators and stakeholders.
Determining actual fugitive landfill gas/methane emissions from the landfill surface is hard to quantify. Drone methane and surface emission monitoring conducted on the landfill surface can determine methane concentrations at receptor points around the landfill surface. These receptor concentrations can be used to run an air dispersion model in reverse to solve for the emission rate of the entire landfill surface. This method also allows you to determine a more accurate control efficiency of the gas collection and control system at the landfill based on landfill gas/methane flow to the combustion device. Want to know more?
Jeff Leadford, PE, of SCS Engineers, is presenting “Modeling Fugitive Methane Emissions With Drones” – a not to miss session! Jeff puts his years of experience in the air quality field, with a focus on air dispersion modeling, air permitting and GIS together with advanced drone technology and modeling techniques demonstrating the effectiveness of combining them, especially for landfill owners and operators.
