CHAPTER 4.1-37 ANHYDROUS AMMONIA FACILITIES
4.1-37-01. Anhydrous ammonia safety rules. The agriculture commissioner shall adopt rules necessary to implement this chapter and
adopt the 2014 American national standard safety requirements for the storage and handling of anhydrous ammonia. The commissioner may adopt rules that deviate from the 2014 American national standard safety requirements if certain provisions of the standard impose undue hardship or if literal adherence to the provisions fails to provide adequate safety.
4.1-37-02. Definitions. As used in this chapter, unless the context otherwise requires: 1. "Anhydrous ammonia storage facility" means a bulk anhydrous ammonia storage
facility with a capacity exceeding six thousand gallons [22712.47 liters] which is owned or operated by a user or vendor of anhydrous ammonia.
2. "Mobile storage container" means a United States department of transportation class MC-331 cargo tank, or an American society of mechanical engineers code constructed and national board registered mobile storage container, approved by the United States department of transportation, used for the temporary storage of anhydrous ammonia to be downloaded into a nurse tank.
4.1-37-03. License required - Anhydrous ammonia facilities and mobile storage container.
The owner or operator of an anhydrous ammonia storage facility or a mobile storage container shall apply to the agriculture commissioner and to the board of county commissioners for a license to site and operate the facility or mobile storage container. Neither an anhydrous ammonia storage facility nor mobile storage container may be operated without a license issued by the agriculture commissioner and the board of county commissioners of the county in which the facility is located. Any permanent anhydrous ammonia storage facility constructed before July 1, 1985, is exempt from the siting requirements of this chapter and may receive a license under this chapter regardless of noncompliance with the siting requirements. The commissioner or the board may deny a license for failure to remit the proper fee for failure to comply with the siting requirements of this chapter and rules adopted under this chapter if constructed after June 30, 1985, or for failure to comply with local siting requirements. The agriculture commissioner also may deny a license if the facility does not meet the initial inspection standards required by this chapter and by any rules adopted under this chapter. To obtain a license, an applicant shall submit with the application two sets of drawings or photographs showing, and two signed affidavits stating, the facility or mobile downloading site has been measured and meets the siting requirements. The drawings or photographs must show the proposed location of the tank and the surroundings in all directions. A set of drawings or photographs must be provided to the agriculture commissioner and a set must be provided to the board of county commissioners. An applicant for a mobile storage container license also shall submit a certification from the United States department of transportation.
4.1-37-04. State license fee. The agriculture commissioner shall charge a one-time twenty-five dollar fee for a private
anhydrous ammonia storage facility or a mobile storage container license, and a one-time one hundred dollar fee for a retail anhydrous ammonia storage facility or a mobile storage container license. Expansion of an existing anhydrous ammonia storage facility does not require reapplication for licensing, but all siting requirements must be met. The license is valid indefinitely but may not be transferred. A new license is required when an anhydrous ammonia storage facility changes ownership.

a. Which is a liquid transfer hose and is not drained of liquid upon completion of transfer operations must be equipped with an approved shutoff valve at the discharge end.
b. Must have a hydrostatic relief valve or equivalent must be installed in each section of hose or pipe in which liquid ammonia can be isolated between shutoff valves to relieve the pressure that could develop from the trapped liquid. If an equivalent pressure relief device is used, the maximum accumulated pressure possible within the system may not exceed the limits of the system. A hydrostatic relief valve must be installed between each pair of valves in which liquid is trapped. The start-to-discharge pressure setting of the relief valve must not be less than three hundred fifty pounds per square inch [2413.18 kilopascals] gauge nor more than four hundred pounds per square inch [2757.92 kilopascals] gauge.
c. Must have etched, cast, or impressed on the outer coating all of the following: (1) The words "ANHYDROUS AMMONIA". (2) The maximum working pressure of the transfer hose. (3) The name of the manufacturer of the hose. (4) The date of manufacture or the expiration date of the hose.
d. Which is cut, scraped, cracked, or weathered so that the inner white cord is visible must be replaced. A transfer hose with an expiration date printed on the hose must be replaced prior to that date. Transfer hoses without an expiration date must be replaced as follows: (1) Rayon hoses must be replaced within two years of the date of manufacture. (2) Nylon hoses must be replaced within four years of the date of manufacture.
