The important metrological factors which affect thedispersion of a pollutant are the average wind speedat the source level at stack height, cloud cover, andambient temperature. Using data from theWashington Dulles International Airport and theRonald Reagan National Airport, the wind speed atthe stack height may be calculated.

GROUND PLUME LEVEL CONCENTRATION

RR = relevant risk of disease due toinhalation of pollutantX = pollutant concentration, (μg/m3)X0 = background concentration in D.C.β = lung cancer coefficient,ex. [PM2.5] = 0.2322

Develop load simulations for different charging scenarios. This allows us to determine if electric vehicle projections are feasible. Create dispersion models for all PEPCO power plants and for each pollutant, including effects of changing fuel mixes through 2040 Correlate health impacts (risk of illness, disease, cancer) with pollutant inhalation Consideration of resident versus commuter driving patterns

people live in urban vs.

rural areas[3].

The Potomac Electric Power Company (PEPCO)has developed projections for their Marylandservice territory [1], which was used to establishpredictions for Washington, D.C. This data iscorrelated with information provided by the DOTOffice of Highway Statistics [2] to calculate thetotal number of vehicles present through 2040.

A survey was distributed to residents of D.C. in order to assess charging habits and build a foundationfor our charging scenarios. EnergyPlus™ is used to model grid capabilities.

WASHINGTON DC SURVEY RESULTS

CO2 DISPERSION FOR NIH

COGENERATION FACILITY

We seek to test the hypothesis that the

adoption and usage of low emission

vehicles positively influences both the air

quality and hence human health in urban

environments. This correlation will impact:

urban planning

transportation and environmental policy

electrification of the transportation sector

Example simulation

using the EPA’s

airborne diffusion

simulation software
