Anhydrous Ammonia Inspector Certification Program

Peeling paint on anhydrous ammonia tanks is extremely dangerous. The exposed tank could rust causing a release of anhydrous ammonia.  Tank must have a reflective white or aluminum surface maintained in good condition.

A broken 0-400 PSI gauge will not be able to measure the pressure inside the tank and needs to be replaced.Broken dial graduated 0-400 PSI gauge needs to be replaced.

•	The quick release coupler is installed on the wrong side and is not bolted down properly. A correctly installed quick release coupler would be mounted on the inside of the bracket and be bolted securely down onto the flatbar. Swivel bracket is installed backwards and the flat bar is missing. Intake section should have a bleeder valve installed. Outlet section should have a hydrostatic relief valve.

The Minnesota Department of Agriculture (MDA) was directed by the 2011 Legislature to write rules and create a certification program certifying inspectors to inspect MDA permitted anhydrous ammonia facilities.  These inspectors will be responsible for assessing a facility’s compliance with the state of Minnesota’s anhydrous ammonia laws and rules.  The intent of such assessments is to help facilities comply with applicable regulations, improve operational safety and ultimately reduce the noncompliance issues found by MDA during its regulatory inspections.

The findings that the certified inspectors provide to the facilities will provide the facility with an important, accurate and real-time compliance assessment.  The information will inform the facilities of the out of compliance items and enable them to make needed repairs. 

This is a voluntary program.  These inspectors will not be employees of the MDA and will not have authority through the MDA to enforce rules and laws or assess penalties.  The MDA will receive notice when a facility has received a certificate of compliance.

The MDA will continue to inspect anhydrous ammonia facilities to determine compliance.  The MDA expects that facilities that have previously passed a certified inspection will have fewer violations during MDA inspections and necessitate less MDA enforcement response.  This program will be the first of its kind in the nation, no other state currently certifies anhydrous ammonia facility inspectors. For more information about the program please read the Frequently Asked Questions.

Minnesota Rules part 1514 was adopted on August 22, 2014 and will take effect January 1, 2017. The MDA will now begin the process of developing the anhydrous ammonia inspector certification program per the requirements listed in the newly adopted rule.

Rulemaking Discussions and Documents

Public Discussions

During the spring of 2013 the MDA held six meetings throughout the state of Minnesota.  More information on these meetings including a summary of each meeting. The thoughts and comments that were presented at these meetings were used as the basis for the creation of the first draft of the rules. The first draft of these rules was posted on this website for informal public comments in January 2014. Following the release of the first draft of rules, there was a listening session in January 2014 held in St. Paul, MN.  This session allowed the MDA to present their reasoning behind the rules and hear from the public their thoughts and concerns on the first draft of the rules. The MDA took the ideas given at these meetings and edited the rule as necessary to address them. A second draft of the proposed rules was sent to all interested parties for further comment in March/April 2014. No comments were received on this second draft and the MDA moved forward with the Notice of Intent to Adopt Rules.
