- Abstract
- This document describes interim procedures for use in accepting, for a specific regulatory application, a model that is not recommended in the Guideline on Air Quality Models. The procedure involves a technical evaluation and a performance evaluation, utilizing measured ambient data, of the proposed nonguideline model. The primary basis for accepting the proposed model is a demonstration that it performs better (better agreement with measured data) that the guideline model or the model that EPA would normally use in the given situation. The acceptance procedure may also consider the technical merits of the proposed model and, especially in cases where an EPA recommended model cannot be identified, the performance of the model in comparison to a set of specially designed performance standards. a major component of the procedure is the development of a protocol which describes exactly how the performance evaluation will be conducted and what the specific basis for accepting or rejecting the proposed model will be.
