8 CCR 1202-5-11 - SYSTEMS MOUNTED ON FARM EQUIPMENT (IMPLEMENTS OF HUSBANDRY) FOR THE APPLICATION OF AMMONIA

This Section applies to systems mounted on farm equipment and used for the field application of ammonia. All General Rules of Section 2 apply to this Section unless otherwise noted.

11.1. Design of Containers

11.1.1. The minimum design for containers shall be in accordance with Rule 3.1.

11.2. Mounting of Containers

11.2.1. All containers shall be securely mounted.

11.3. Container Valves and Appurtenances

11.3.1. Each container shall have a fixed maximum liquid level gauge.

11.3.2. The filling connection shall be fitted with combination back-pressure check valve and excess-flow valve; one double or two single back-pressure check valves; or a positive shut-off valve in conjunction with either an internal back-pressure check valve or an internal excess-flow valve.

11.3.3. An excess-flow valve is not required in the vapor connection, provided the controlling orifice is not in excess of seven sixteenths (7/16) of an inch in diameter and the valve is a hand-operated (attached hand wheel or equivalent) shut-off valve. To assist in filling applicator tanks, it is permissible to bleed vapors to the open air, providing the preceding requirements are met.

11.3.4. Metering devices may be connected directly to the tank withdrawal valve. A union type connection is permissible between the tank valve and metering device. Remote mounting of metering devices is permissible using hose which meets with specifications set out in Appendix B of this Rule. When the applicator tank is trailed and the metering device is remotely mounted, such as on the tractor tool bar, an automatic break-a-way type, self-closing, coupling must be used.

11.3.5. No excess-flow valve is required in the liquid withdrawal line provided the controlling orifice between the contents of the container and the outlet of the shut-off valve (see 2.5.5) does not exceed 7/16 inch in diameter.
