2. Emissions Calculation & Regulatory Analysis Workbook
The APCD has developed a form to assist you in completing your emissions calculations and regulatory analysis, and closely reflects internal forms used for the same purpose. The use of this form is optional, and this form does not necessarily include all types of equipment or all possible regulatory scenarios. This form is updated periodically. 
3. Complete Attachments A through J for your application.
Your APEN will be rejected if it is filled out incorrectly, is missing information, or lacks payment for the filing fee. The re-submittal will require a new filing fee. See our Application Rejection Frequently Asked Questions page for more information.
