No. 99-0062\nVanHool N.V.\nBernard Van Hoolstraat 58\nB-2500 Lier Koningshooikt\nBelgium\nDear Mr. Vleugels:\nThis is in response to your letter dated February 3, 1999, requesting clarification on the transportation\nof \"Sodium Sulfide, hydrated with not less than 30% water, 8, UN 1849, IT\" under the Hazardous\nMatenals Regulations (HMR; 49 CFR Parts 171-180). Specifically, you ask whether the provisions in\n§§ 173.32c (g)(2) and 173.32c (j) concerning bottom outlets and filling density apply to a solid\nmaterial.\nThe bottom outlets and filling density provisions apply to liquid and flowable solid hazardous materials,\nnot to solid or non-flowable solid hazardous materials./ The provisions of § 173.32c (i) were *\ndeveloped to cover liquid and flowable solid hazardous materials transported in IM portable tank t\npackagings. This provision was intended to minimize the risk of accidents resulting from slosh and the\nshift of the center of gravity.\nThis has been further clarified under Docket HM-215C, \"Harmonization with the United Nations\nRecommendations, International Maritime Dangerous Goods Code, and International Civil Aviation\nOrganization's Technical Instructions; Final Rule (64 FR 10742) published March 5, 1999. Under\nDocket HM-215C, § 173.32c (j) has been revised for consistency with the UN Recommendations.\nThe provision excluding non-flowable solids is broadened to include viscous liquids with a low flow\nrate. In § 173.32c paragraph (i) is revised to read \"except for a non-flowable solid or a liquid with a\nviscosity of 2,680 centistokes (millimeters squared per second) or greater at 20 degrees C, an IM\nportable tank or compartment thereof having a volume greater than 7,500 L (1,980 gallons) may not be\nloaded to a filling density of more than 20% and less than 80% by volume. If a portable tank is divided\nby partitions or surge plates into compartments of not more than 7,500 L capacity, this filling restriction\ndoes not apply.\"\nI hope this answers your inquiry.\nSincerely,\nMeth\nDelmer F.
