To facilitate review of the draft 2022v1 data, LADCO developed a web application to compare emissions across recent inventories (2016-2022) for different pollutants. A description of the two apps are below, followed by a description of the data sources.
The R-Shiny web apps generate stacked bar charts of inventory data. The segments in each bar show the annual emissions (tons/year) for different inventory sectors. The user interface of the charts allows the selection of multiple inventory pollutants, a single state, and multiple inventory years. Click on each link below to launch the apps.
State Bar Charts and Tables (click to launch)
Each bar shows the total annual emissions for the selected pollutant, state, and inventory year. Users can select multiple pollutants, a single state, and multiple inventory years to populate the chart. A table of data in each chart is included below the charts. The table can be filtered using the “Search” box or sorted by clicking on the header of each column.
State Difference Charts (click to launch)
Each bar shows the difference in annual emissions for the selected pollutant, state, and two inventory years. Users can select multiple pollutants, a single state, and two inventory years to populate the chart. The top chart shows the absolute difference between the inventory years (e.g., 2022 – 2016) and the second chart shows the percent difference between the years (e.g., (2022 – 2016)/2016 * 100). To interpret these difference charts, find the zero line on the y-axis to identify the sectors that increased or decreased across the two selected years.
The data in these charts are from the U.S. EPA 2022v1 draft emissions modeling platform. The specific data file behind these charts is the state-EISSectorGroup-trends spreadsheet that is available from the 2022v1 draft data files and summaries.

Location: Virtual (Online)
Instructors: Chris Dresser
Course Registration Link – Register by May 13, 2024
Who Should Attend: This course is intended for those who will be involved with the development of NEPA, SIP, and regional conformity emissions estimates or will be reviewing of such analyses. Participants must bring their own laptops with MOVES4 installed. The model is available from EPA’s website: https://www.epa.gov/moves/latest-version-motor-vehicle-emission-simulator-moves#download
About the Course: The purpose of this training is to provide attendees with an overview of EPA’s MOVES4 mobile source emissions model. It will cover the functionality of the model, input requirements, output processing, and will address relevant EPA and FHWA guidance documents. The course also includes hands-on exercises that will demonstrate several realistic modeling scenarios applicable to GHG, conformity (regional and project-level), and NEPA analyses. The intended audience are those who use (or expect to use) MOVES or those who will be reviewing MOVES-based analyses.
Course Delivery: This is a virtual, instructor-led training.
How to Register: See the U.S. EPA LMS Frequently Asked Questions for how to create an account, register for a course, and other common functions.

]]>Back in 2005-2006 during the first Regional Haze implementation period, on behalf our member states, LADCO contracted projects to review candidate emissions control measures for particulate matter (PM) and PM precursors, including VOC and SO2. The white papers and reports from these projects are available on the Reports -> Policy Support section of the LADCO website. Some of these rules were adopted by some of the LADCO states at the time. The Phase II Final Report in this archive is linked to on several industry websites in reference to LADCO VOC limits.
A list of state contacts to whom inquires about current state VOC limits should be directed are provided on the LADCO Policy Support page. If you have questions about VOC rules for a particular solvent or chemical, use those contacts to directly contact the state agency.
