Compliance Corner: Navigating the Regulatory Realm |
The U.S. Environmental Protection Agency (EPA) has introduced significant updates to its Greenhouse Gas Reporting Program (GHGRP) for 2024. Key changes include revisions to subpart W (Petroleum and Natural Gas Systems), subpart C (General Stationary Fuel Combustion Sources), and subpart A (General Provisions). These updates address gaps in emissions data reporting for specific sectors and establish new confidentiality determinations. Additionally, the EPA has updated the global warming potentials (GWPs) and expanded the GHGRP to include new source categories, enhancing data collection and program implementation.
Another notable update is the introduction of the Waste Emissions Charge (WEC) for methane emissions, impacting facilities reporting under subpart W. This proposed rule outlines the charge implementation details, including calculations and exemptions. These updates aim to improve the accuracy and comprehensiveness of greenhouse gas emissions reporting, ensuring better regulatory compliance and environmental protection.
Contact us today to learn how our AQMIS Air Quality Management Solution can be used to ensure compliance with EPA air quality regulations including the recent revisions to Appendix W.
For more details, you can visit the EPA's Rulemaking Notices for GHG Reporting.

Lakes Environmental at A&WMA Conference and Exhibition |
 |
|
We are incredibly grateful to everyone who visited our booth at the A&WMA Annual Conference and Exhibition in Calgary from June 24-27, 2024. It was a pleasure meeting each of you, and we hope you found the conference as enriching and enjoyable as we did.
We're excited about the opportunities to collaborate over the coming year and are already looking forward to reconnecting at the next A&WMA Annual Conference in Raleigh in 2025. See you there!

MODELING TIP |
Run CALMET in Parallel with CALPUFF View |
|
One limitation of the CALPUFF air dispersion model is that it can only be executed on a single processor (i.e., serially). Previous modeling tips have discussed ways around this limitation. For example, executing CALPUFF with a single source will run faster than attempting to model multiple sources at a time. Modelers can then employ CALSUM to assess cumulative impacts. This approach has the added benefit of providing a way to assess individual source contributions.
While the default CALMET executable is also a serial process, Lakes Environmental’s CALPUFF View application has long included the ability to parallelize these runs. This allows modelers to complete CALMET assessments in a fraction of the time. CALPUFF View’s multi-processor functionality for CALMET divides the CALMET run up into pieces that can be executed simultaneously across multiple processors. Users can select the number of processors they want to use with no limits, based on the number of processors available on their machine. To enable CALMET Parallel, follow the steps below.
Step 1: Navigate to the application Preferences under the File menu.
Step 2: Select CALMET under the EPA Models/Limits heading.
Step 3: Enable the Use Multi-Processor Options and select the number of processors to use.
This can also be enabled from the Project Status – CALMET dialog that appears just prior to executing the model.
When executing CALMET Parallel, CALPUFF View will evenly divide the run period amongst the number of processors selected (with a minimum run period of 24 hours per run). Each piece is then run at the same time to complete the full period in record time.
