The Master Matrix must be completed by operations applying for a construction permit, unless they can meet one of the following two exemptions:

• The county, where the operation is located or will be located, has not adopted the construction evaluation resolution or does not have a valid construction evaluation resolution when the application is submitted; OR
  
  
• The operation was first constructed prior to April 1, 2002 and is expanding to an animal unit capacity (AUC) of 1,666 AU or less. This exemption applies in all counties.

Note: producers must also submit the supporting master matrix documents (e.g. design, operation and maintenance plans as written in certain matrix items).
