Specifically, you ask several questions regarding the inspection and testing of nurse tanks when securely mounted to a field truck, farm wagon, or an applicator trailer. We have paraphrased your questions and answered them in the order you provided. Q 1. You ask whether a nurse tank securely mounted on a field truck is required to be tested in conformance with the§ 180.407(h) leakage test, as prescribed in§ 173.315(m)(3)(ii). A 1. The answer is yes. When securely mounted to a field truck, a nurse tank must comply with the provisions in§ 173.315(m)(3), which include the applicable testing and inspection requirements for an MC 331 cargo tank under subpart E of part 180, (Qualification and Maintenance of Cargo Tanks). See§ 173.315(m)(3)(ii). Q2. You ask whether the leakage test in § 180.407(h) applies to all nurse tanks regardless of their placement on a field truck, farm wagon, or applicator trailer. A2. The answer is no. Only nurse tanks securely mounted on a field truck in accordance with § 173.315(m)(3) are subject to a leakage test as prescribed in§ 180.407(h). Q3. You ask whether rollover protection, prescribed in§ 178.337-10 as "accident damage protection," for an MC 331 cargo tank motor vehicle is required on a nurse tank mounted on a farm wagon, applicator trailer, or field truck. <<>> A3. The answer is no. The HMR do not require accident damage protection for non- specification nurse tanks under § 173 .31 S(m). I hope this information is helpful. Please contact us if we can be of further assistance. Sincerely, T. Glenn Foster Chief, Regulatory Review and Reinvention Branch Standards and Rulemaking Division <<>> £ c;lrv-L~ ?J /8CJ.
