FIELDS OF EXPERIENCE:

Ms. Loomis specializes in emissions inventory preparation and emissions modeling for regional and urban scale photochemical and particulate modeling applications, environmental database design and implementation, and the statistical analysis of sampling data. She has experience in using all of the major emissions modeling systems, including SMOKE, EMS-2001, EMS-95, EMS-95/PM, SMOKE, GEMAP, EPS2.0 and FREDS. She has also developed and presented user training classes in emissions modeling. Her areas of expertise include the following:

Emissions Inventory Modeling

Ms. Loomis has prepared emissions inventories for photochemical and particulate modeling using SMOKE, EMS-2001, EMS-95, EMS-95/PM, GEMAP, EPS 2.0 and FREDS.

Ms. Loomis has been involved in all phases of emissions modeling, including the development of spatial, temporal and speciation factors for 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.

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, 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 recently 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.

Training

Ms. Loomis has developed and presented a number of training sessions on emissions modeling systems, including training on both EMS-95 and EPS 2.0. Clients include US EPA, California Air Resources Board, 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.
