This document outlines the process for developing an inventory for Class II Increment Analysis in New Mexico. It details the selection of point and non-point sources, emphasizing the importance of using allowable emissions as a screening tool and refining with actual data where necessary. It also covers key data handling aspects, such as tracking emissions, incorporating mobile and area sources, and addressing missing data using AP-42 estimates. Collaboration with interstate and tribal entities is encouraged for comprehensive emissions tracking.

Building an Inventory for Class II Increment Analysis in New Mexico Mary Uhl, New Mexico Environment Department
Selecting Point Sources for the Inventory • Use allowables as a “screening” analysis • Refine with actuals where available/necessary • Include major and minor sources within 50 km of the radius of impact • Include sources located in the AQCR for more than 1 year
Selecting “Non-Point Sources” for the Inventory • Include mobile and area sources in areas of growth • Include “intermittent” sources that have significant emissions
Missing Data • Use allowables where available • Assume full increment available at minor source baseline date • Use AP-42 estimates/historical information about industry class to “construct” baseline
Database Requirements • Track short-term and annual emission rates • Ability to segment emissions within the facility • Designation for increment consuming, expanding and baseline emissions • Ability to track stack parameter changes • Interstate/tribe coordination possible
