The Challenges of Using AERMOD to model the cumulative impact from Projects located near Environmental Justice Areas

USEPA’s AERMOD atmospheric dispersion model can be used to document that under specific operational conditions stationary sources will neither cause nor contribute to conditions of air pollution and will comply with the National Ambient Air Quality Standards (NAAQS). Results from AERMOD modeling typically form the basis for emission limits in a stationary source air permit. While analyses for addressing Environmental Justice concerns involve combining information on nearby stationary sources of pollution and mobile sources. Projects must assess the baseline health of the community; account for multi-pollutant exposure; analyze alternatives; and assess the effectiveness of any mitigation measures.

The Off-Shore Coastal Dispersion (OCD) Model and an Off-Shore Wind Farm: When the Future Must Conquer the Past

Construction of offshore wind farms in federal waters requires permits that confirm that ambient air quality is not adversely impacted both during construction and during ongoing operations. This paper discusses current challenges in preparing suitable meteorological datasets of acceptable quality for federal regulatory authorities as required for these over-water modeling applications. Specifically, we compare air modeling results of traditional observational data in an over-water modeling application with data generated from the Weather Research and Forecasting (WRF) model processed using the Mesoscale Meteorological Interface Program (MMIF).

WRF-MMIF versus Observational Meteorological Data Challenges in an Overwater Environment

Over the past five years, offshore wind has re-emerged, with several procurements on the east coast of the United States. The construction of a wind farm in federal waters requires an Outer Continental Shelf (OCS) permit, and (because construction emissions are counted) can trigger Prevention of Significant Deterioration (PSD) requirements. One of the requirements of a PSD permit is the documentation that ambient air quality is not adversely impacted by the construction and operation of an offshore wind farm using air dispersion modeling.
