Dear Mr. Meister:
This is in response to your letter, and subsequent telephone conversation with Diane LaValle, of my staff, requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). 1 apologize for the delay in response.
Your questions are answered as follows:
Ql. Are nurse tanks with a capacity of 3000 gallons or less that meet construction specifications required at the time of manufacture authorized for the transportation of anhydrous ammonia?
A. As provided by § 173.315(m) a nurse tank transporting anhydrous ammonia, operated by a private carrier exclusively for agricultural purposes does not have to meet the specification requirements of 49 CFR Part 178 if, among other criteria, it meets the requirements of the ASME code in effect at the time it was manufactured.
Q2. As provided by § 173.315(m)(5), a nurse tank transporting anhydrous ammonia may be loaded to a filling density no greater than 56 percent. Using the water weight factor of 8.32828 pounds per gallon, would a 3000 gallon tank loaded to 56% by weight have a maximum loaded weight of 13,991.51? [3000 X 8.32828 X 56%]
A. The maximum weight of anhydrous ammonia authorized in this cargo tank is 13,991 pounds which does not include the weight of the cargo tank and motor vehicle.
Q3. There is a difference in the maximum permitted filling densities in § 173.315(a) and § 173.304. Please explain the difference.
A. Section 173.315 pertains to cargo tanks, whereas § 173.304 pertains to cylinders.
Q4. What are the requirements of the Compressed Gas Association's (CGA) pamphlet S1.2?
A. Pamphlet S1.2 may be purchased from the CGA. They may be contacted at (703) 412-0900.
I hope this information is helpful.
Sincerely,
