Preparation, Analysis and Review of Emission Inventories

Pennsylvania Biofuels.  As a subcontractor to E.H. Pechan, Ms Loomis is managing an ambient air quality study to determine if the mandated volumes of biofuel in fuel sold or offered for sale in the Pennsylvania Commonwealth will achieve and maintain the NAAQS for ozone and fine particulate matter (PM2.5).    Using SMOKE, MOBILE6.2, and CMAQ,   alternate scenarios for biodiesel penetration are being evaluated for 2008 and 2012 to determine the impact of ethanol, biodiesel fuel sales and alternatives.

Hong Kong Air Quality Modeling System.  Ms Loomis is the Alpine Geophysics Project Manager for the development of an enhanced air quality modeling system for the Hong Kong Environmental Protection Department (EPD).  As a subcontractor to ENVIRON, AG is responsible for the incorporation of the emissions modeling systems, including both CONCEPT and SMOKE alternatives.  The modeling system options include MEGAN and BEIS capability, generation of emissions inputs for the CBM4, CB05 and SAPRC99 chemical mechanisms, and motor vehicle emission factor options generated by EMFAC and MOBILE6. Geophysical data used for spatial allocation of emissions, temporal allocation factors and speciation profile data has also been reviewed, updated and incorporated into the modeling systems.  

Denver SIP Modeling.  Ms Loomis has prepared the emissions inventory and emissions modeling for the Denver Metropolitan Area (DMA) and adjacent regions 8-hour ozone modeling analysis in support of the development of an 8-hour ozone State Implementation Plan (SIP) and attainment demonstration.  The Denver 8-Hour ozone SIP modeling includes emissions, meteorological and ozone simulations using a nested 36/12/4 km grid with the 4-km grid focused on the state of Colorado and including the DMA and vicinity.  Key portions of the emissions development include on-road and off road fuel alternatives, and enhanced emissions speciation and spatial allocation for oil and gas emissions.

Visibility Improvement - State and Tribal Association of the Southeast (VISTAS) regional planning organization (RPO).  Developed, modeled and reviewed emissions inventories in support of VISTAS air quality modeling programs. This assignment encompasses the development of 2002, 2009, and 2018 inventories for VISTAS, including the development of national, annual on-road motor vehicle inventories utilizing MOBILE6 and SMOKE, CEM-based EGU emissions inventories, area and point source inventories utilizing NEI and locally updated emissions data, NONROAD based emissions estimates and projections for off-road mobile sources, BEIS3 biogenics, and wildfires.

SIP Strategy Comprehension Plan (SSCP). Examination of the components of an integrated 8-hr ozone and annual PM2.5 modeling study for the five-state Upper Midwest region.  The aim of the SSCP is to allow the Project Sponsors insight and assurance that best modeling practices are being utilized to identify effective emission reduction controls to address the residual nonattainment issues in this region and that if alternate and credible information are developed independently outside of the scope, timelines, or budgets of the RPO recommendation process that these data are introduced to the States in a constructive manner for consideration in SIP development timelines.

Mid-Atlantic Regional Air Management Association (MARAMA).  Provided revision, analysis, and adjustment of the 2002, 2009, 2012, and 2018 base case and control scenario emission estimates for the MANE-VU region.

Ms Loomis has recently provided emissions inventory development and modeling to a number of industrial groups, examining the effects of specific plant alterations, retrofits, and alternate control scenarios on local and regional air quality.

 Ms Loomis has recently developed particulate inventories for national scale modeling, utilizing the EMS-2001/MOBILE6.2 modeling system. She is also involved in the development and QA of SIP quality inventories for particulate and photochemical modeling in California. 

Ms. Loomis has been involved in, and developed inventories for, numerous recent projects examining the effects of the 1999 NOx SIP call budgets and investigating the impacts of budget alternatives, including alternate point, area, and on-road motor vehicle control strategies. These projects have utilized emissions data from a wide variety of sources including the OTAG emissions databases, the EPA’s NEI and NET inventories, data acquired from state and local jurisdictions, continuous emissions monitoring (CEM) data, and facility supplied emissions data.

Ms. Loomis has  prepared PM-10 and ammonia emissions inventories in support of particulate modeling and research in the state of California.  These inventories were prepared for the San Joaquin Valley modeling region, and have required the synthesis of emissions data from a variety of sources, including the NAPAP emission inventories, NEI, California state inventories of air toxics and criteria pollutants (CEIDARS), and other modeling inventories (SARMAP); and the calculation of emissions from available emissions factors and activity data.

Ms. Loomis has developed emissions modeling inventories for use in SIP planning for a number of projects, including:  Pittsburgh-Beaver Valley Ozone Modeling Study, Pennsylvania Stakeholders Ozone Modeling Study, Cincinnati-Hamilton Ozone SIP Modeling Study, Lower Lake Michigan Ozone SIP Modeling Study, Stakeholder Participation in the OTAG/EPA NOx SIP Call Modeling, the South Central Coast Air Basin of California, Ventura County, and Santa Barbara County. These emissions were synthesized from a variety of sources, including emissions inventories developed for OTAG, state and local agency records, and CEM data provide by local utilities.

Ms. Loomis has developed emission inventories to examine the air quality impacts of various alternative motor vehicle fuels and motor vehicle controls strategies, including the Northeast OTC, the Great Lakes region, the Western US, and the South Coast Air Basin in California.  These inventories have included the derivation and development of alternate speciation profiles to examine the impacts of reformulated fuels., the development and application of alternate emission factors, and modeling the effects of new and proposed emission control technologies.

Development of Data in Support of Emissions Processing Tools

Ms Loomis was the project manager for the development of the Consolidated Community Emissions Processing Tool (CONCEPT)  Under contract to LADCO, the CONCEPT model  CONCEPT is a PostgreSQL-based system whose goal is to house all data related to the emissions modeling process under a single data base.  GIS-related functions are managed within the same PostgreSQL data base using the PostGIS plugin.

Ms. Loomis designed and developed the on-road motor vehicle emissions estimation model of EMS-2001, integrating the MOBILE6.2 model into the EMS system.  Ms. Loomis is currently developing national scale on-road motor vehicle emissions for particulate and ozone modeling, using the newly release MOBILE6.2, combined with the EMS-2001 modeling system

Ms. Loomis has been involved in all phases of emissions modeling, including the development of spatial, temporal and speciation factors for CONCEPT, SMOKE, EPS 2.0 and EMS-95 modeling efforts, often in response to specific projects needs.   Examples include the development of speciation profiles for oil and gas seeps off the California coast, development of speciation profiles for reformulated fuels for California and Pittsburgh, development of spatial allocation factors for agricultural emissions in the San Joaquin Valley, development of temporal allocation profiles specific to ammonia emissions, and application of specialized temporal and spatial allocation of shipping and wildfire emissions in both Florida and California.

Technology Transfer Activities

Ms. Loomis has developed and presented a number of training sessions on emissions modeling systems, including training on CONCEPT, EMS-95 and EPS 2.0. Clients include US EPA, California Air Resources Board, Lake Michigan Air Directors, Missouri DNR, Kansas DNR, private industry, and other consultants.  These training sessions include lecture and hands-on application of the selected models, discussion of various approaches and pitfalls common in emissions modeling, discussion of the available modeling alternatives, and selection criteria for appropriate emissions models given project requirements and restrictions.
