During New Source Review modeling of proposed major sources of oxides of nitrogen (NO), maximum impacts are often predicted to occur very close to the source. At the same time, current modeling guidance recommends techniques that may be overly conservative in estimating the fraction of nitrogen dioxide (NO) in these plumes. A new technique called the Plume Volume Molar Ratio Method (PVMRM) is being proposed that simulates both chemistry and dispersion to better estimate the fraction of NO. This paper documents the methodology behind the technique. A follow-up pa-per will evaluate its performance against a number of databases. This method is designed to realistically predict NO fraction at close-in receptors yet still provide conservative estimates so that the air quality standards can be protected.
在对拟议的氮氧化物（NO）主要排放源进行新源审查建模时，通常预计最大影响会发生在离排放源非常近的地方。与此同时，当前的建模指南推荐的技术在估算这些烟羽中二氧化氮（NO₂）的比例时可能过于保守。一种名为羽流体积摩尔比法（PVMRM）的新技术被提出来，它能同时模拟化学过程和扩散，以更好地估算NO的比例。本文记录了该技术背后的方法。后续论文将根据多个数据库评估其性能。该方法旨在实际预测近距离受体处的NO比例，但仍提供保守估计，以便保护空气质量标准。
