Box 382, 4232 West White Pine County Rd 44\nRuth, NV 89319\nReference No. 16-0177\nDear Mr. Thompson:\nThis letter is in response to your October 17, 2016, letter requesting clarification of the\nHazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to shipping a\nhazardous substance. You provide a scenario in which a hazardous substance (molybdenum\nconcentrate) in a bulk package is offered for transportation by highway.\nWe have paraphrased and answered your questions as follows:\nQI. Is a hazmat endorsement on a commercial driver's license (CDL) required to transport\nmolybdenum concentrate in a bulk package?\nAl. The answer is no. Section 172.504(t)(9) states that a CLASS 9 placard is not required for\ndomestic transportation. Therefore, the Federal Motor Carrier Safety Regulations\n(FMCSR) would not require a driver to have a hazmat endorsement on a CDL.\nQ2. Is a driver required to have hazmat training in accordance with Subpart Hof Part 172 if\nthe driver has a hazmat endorsement on a CDL?\nA2. In accordance with§ 177.800(c), each driver who .is a hazmat employee is subject to the\ntraining requirements in Subpart H of Part 172) and the driver training requirements in\n§ 177.816, regardless of whether a hazmat endorsement is required. However, the\ntraining required to obtain a hazmat endorsement may be used to satisfy the training\nrequirements of the HMR to the extent that such training addresses the training\ncomponents of§ 172.704(a).\nQ3. In the scenario provided, are placards required on each bag of molybdenum concentrate,\nas well as the outside of the transport vehicle?\nA3. See Al. Placards are not required on each bag or the transport vehicle. However,\nidentification number markings are still required on each bulk package in accordance\n'\"\"·\n\n<<<PAGE 2>>>\n\nQ4. A4. Q5. A5. with § 172.302. In accordance with § 172.332, a placard, an orange panel, or a white\nsquare-on-point are all acceptable methods of displaying the identification number.\nFurthermore, § 172.33 l(c) states that ifthe identification number marking on a bulk\npackage is not visible because it is contained inside a transport vehicle or freight\ncontainer, the identification number marking must be displayed on each side and each\nend of the transport vehicle.\nWhen is a driver required to meet the training requirements in the HMR?\nDrivers meeting the definition of a \"hazmat employee\" in accordance with § 171.8 are\nsubject to the training requirements in the HMR.\nWhat are the requirements for shipping 16 bags of molybdenum concentrate weighing\n3,000 pounds each?\nA material that meets the definition of a hazardous material is subject to all applicable\nrequirements of the HMR unless specifically excepted, including, but not limited to:\npackaging, hazard communication (e.g., shipping papers), and training requirements.\nI hope this information is helpful. Please contact us if we can be of further assistance.\n\n<<<PAGE 3>>>\n\n\"'=-- - - •\n...\n0KGHM\n~1 -\"7')_ SOD.\nPl Q-Conc!L()£\n)lo-Ol l'l\n17 October 2016\nU.S. DOT\nPHMSA Office of Hazardous Materials Standards\nAttn: PHH-10\nEast Building\n1200 New Jersey Avenue, SE.\nWashington, DC 20590-0001\nDear Office of Hazardous Materials Standards,\nI would like to kindly request an interpretation rega rding shipment requirements\nfor molybdenum concentrate. The Robinson Nevada Mining Company produces this\nproduct on site in Northern Nevada and ships to end users in different parts of the\nUnited States. The molybdenum concentrate is shipped in bags that weigh\napproximately 3,000 pounds each. A \"sales lot\" shipment is typically made up of 16\nbags that are shipped at once via a flatbed truck.\nRobinson's molybdenum concentrate is currently classified as class 9, UN3077,\nPacking group Ill, RQ and is flagged as an environmentally hazardous substance\nsince arsenic and phosphorus are contained within .\nBased on the above classification, I respectfully request an interpretation on the\nfollowing:\n1. Is a Hazmat endorsement on a CDL license required to transport this\nmaterial in the quantities stated above?\n2. Does a Hazmat endorsement on a CDL override the PHMSA introductory\ntraining class?\n3. When shipping this product, are placards required on the bags as well as on\nthe transport truck? Would placards only attached to each bag suffice?\nRobinson Nevada Mining Company\nRobinson Mine\nP.O.

Symptoms\ninclude severe shortness of breath, weakness, and weight loss and the\nsilicosis can lead to fatal respiratory failure.\nChronic Toxicity of Respirable Silica\nInhalation: Chronic silicosis can occur after 1 O or more years of exposure at\nrelatively low concentrations of respirable crystalline silica. Symptoms\nmay not be obvious but as the disease progresses, shortness of breath\nduring exercise and poor oxygen/carbon dioxide exchange are\nprevalent, in addition to fatigue and chest pain. Lung damage occurs\nfrom inhalation of particles < 10 microns in diameter (micron or\nmicrometer== one one-thousandth of a millimeter). Accelerated silicosis\ncan develop after 5-10 years from first high exposures. Severe\nPage 3 of 7\n\n<<<PAGE 8>>>\n\nInterim Final\nIssue Date: February 3, 2006\nshortness of breath, weakness, and weight loss occur from silicosis.\nThe fibrosis of the lungs is often diffuse and irregular.\nCarcinogenicity:\nRespirable crystalline silica has been identified by NIOSH as a potential\noccupational carcinogen. NIOSH's Hazard Review of the Health\nEffects of Occupational Exposure to Respirable Crystalline Silica states\nthere are studies which support lung cancer is associated with\noccupational exposures to crystalline silica (2002). ACGIH (2005) lists\nsilica crystalline quartz as a suspected human carcinogen.\nAcute Toxicity of Molybdenum:\nInhalation:\nOral (ingested):\nPotential irritant to the eyes and lungs (Occupational Health Guideline\nfor Molybdenum and Insoluble Molybdenum).\nLimited information. An FDA study indicated there were no observed\nchanges in rats over a 4-week period following inhalation exposures to\nmetallic molybdenum at 25,000 to 30,000 mg/m3 or to molybdenum\ndioxide at 10,000 to 12,000 mg/m3 for one hour. Workers exposed to\n60 to 600 mg/m3 of molybdenum reported increase of non-specific\nsymptoms such as weakness, fatigue, headache, anorexia, and joint\nand muscle pain (NIOSH-IDLH Documentation).\nLimited information. A toxicity study (Fairhall et al. , 1945) reported in a\nPublic Health Bulletin that no fatalities in animals occurred from\ningestion of large doses of molybdenum disulfide (NIOSH-IDLH\nDocumentation).\nChronic Toxicity of Molybdenum:\nInhalation: Oral (ingested):\nACGIH (American Conference of Governmental Industrial Hygienists)\nhas listed the basis for the Threshold Limit Values (2005) for\nmolybdenum metal and insoluble compounds as critical effects to the\nlungs and central nervous system. EPA's Integrated Risk Information\nSystem database for molybdenum does not have information for\ninhalation risk. Long term exposure effects are not known, according to\nthe Occupational Health Guide for Molybdenum and Insoluble\nMolybdenum (U.S. Department of Health and Human Services and\nU.S. Department of Labor).\nStudies of human and animal ingestion suggest that molybdenum has\nan adverse effect on copper homeostasis that can change the level of\nserum ceruloplasmin. An increased level of serum ceruloplasmin and\nurinary excretion of copper observed in some human studies indicates\nhigh levels of molybdenum maybe associated with potential mineral\nimbalance (US EPA Integrated Risk Information System).\nMolybdenum intake of 0.14 mg/kg-day may result in serum uric acid\nlevels elevated above the average range of the adult population. This\nlevel is designated as the LOAEL (lowest observed adverse effect\nlevel) and a reference dose for chronic oral exposure (RfD) of 5E-3\nmg/kg-day (US EPA -Integrated Risk Information System (IRIS,\nrevision of August 1, 1993)).\nCarcinogenicity:\nACGIH lists soluble molybdenum compounds as confirmed animal\ncarcinogen in high doses with unknown relevance to humans.\nPage 4 of 7\n\n<<<PAGE 9>>>\n\nInterim Final\nIssue Date: February 3, 2006\nAvailable evidence does not suggest that soluble molybdenum\ncompounds are likely to cause cancer in humans except under\nuncommon or unlikely routes of exposure. No data available on metal\nand insoluble compounds (ACGIH, USEPA, ATSDR, NIOSH).\nMutability:\nLimited information available; human effects undetermined at this time.\nSection XII\nEcological Information\nMolybdenum is an essential, trace element for animals and plants. Compounds of molybdenum form\nsome of the scarcer constituents of the earth's crust -approximately 3 times more abundant than gold.\nThe exposure routes of molybdenum to animals are inhalation, ingestion, and physical contact. High\nintake of molybdenum can produce a condition known as molybdenosis in animals. A study to compare\nthe effects of various molybdenum compounds showed that 500 mg of molybdenite (MoS2) ingested daily\nwas non-toxic, but animals receiving molybdenum trioxide, calcium molybdate, and ammonia molybdate\nshow anorexia, listlessness, and weight loss (Marston, H.R., Cobalt, Copper, and Molybdenum in the\nNutrition of Animals and Plants, Physiol. Rev. 32, 66 (1952).\nThe element molybdenum is a component of a pterin coenzyme essential for the activity of xanthine\ndehydrogenase, xanthine oxidase, sulfite oxidase, and aldehyde oxidase-moco dependent human\nenzymes. Xanthine dehydrogenase catalyzes the conversion of hypoxanthine to xanthine, and xanthine\nto uric acid. It also catalyzes the reactions of purine end metabolism. Molybdenum is essential in the\nmetabolism of sulfites to sulfates-sulfite being toxic to the nervous system (Information from National\nAcademy of Sciences/National Research Council, PDR Health publication, part of Thomson Healthcare,\nand Merck Manual -Section 1, Chapter 4, Mineral Deficiency and Toxicity).\nA study of Lin Xian, a small region in Honan Province of China, found that the low presence of\nmolybdenum in the soil contributed to the nitrates in the soil being converted to nitroamines instead of\namines. Nitroamines are known carcinogenic substances. Nitrates in the soil require a molybdenum -\ndependent enzyme (n itrate reductase) to reduce the nitrates to nitrogenous substances for plant nutrition.\nThis province area of China had one of the highest incidences of esophageal cancer until the soil was\nenriched with molybdenum. It is believed that the incidence of cancer is declining with the introduction of\nthe molybdenum enriched soil (PDR Health publication, part of Thomson Healthcare).\nIt has also been reported that high concentrations of molybdenum can be injurious to plants, depending\non the concentration and species. Oats exposed to concentrations of 50 mg/L of molybdenum exhibited\na slight effect where as at 200 mg/L of molybdenum the oats exhibited stunted growth. Soybeans and\nflax exhibited toxic effects at a concentration of 10-20 mg/I molybdenum (Water Quality Criteria,\nPublication 3-A, reprinted 1973, California Water Resources Control Board).\nStudies of fish and other aquatic life also show variability in the deleterious concentration of molybdenum\nand molybdenum compounds depending on the hardness of the water and the species. Several species\nof algae concentrate molybdenum from water by a factor of 2 to 15. A species of Daphnia tolerate\nconcentrations of 1000 mg/L of molybdenum without perceptible injury (Water Quality Criteria,\nPublication 3-A, reprinted 1973, California Water Resources Control Board).\nSection XIII: Disposal Considerations\nIf spilled material cannot be reused in the process, it is recommended to sample and analyze for metals,\nprior to disposal. Follow national, regional or local regulations governing the disposal of waste materials.\nPage 5 of 7\n\n<<<PAGE 10>>>\n\n·--:;-..\nInterim Final Issue Date: February 3, 2006\nSection XIV: Transportation Information\nShip as: Environmentally hazardous substance, solid, n.o.s., (arsenic, phosphorus), Marine Pollutant\n(copper), 9, UN 3077, Ill RO.\nReportable Quantity for Arsenic and Phosphorus is 1 pound in 49 CFR 172.101-Hazardous Materials\nTable, Appendix A and in 40 CFR 302, Table 302.4.

Molybdenum is not on the list of specific toxic chemicals (40\nCFR 355.65) subject to applicable reporting and notification under the\ntoxic chemical release reporting (Form R) section of the EPA\nregulations (40 CFR 372.85).\nConventional/Non-Conventional Pollutant under Section 307(a) of\nCWA; 40 CFR Part 122, Appendix D, Table IV.\nMolybdenum is not a substance regulated under 40 CFR 141.86 and\n141 .88.\nMolybdenum is not on the list for toxicity characteristics under the\nRCRA regulations (40 CFR 261 .24). Other metals associated with\nmolybdenum are on the list for toxicity characteristics, such as but not\nlimited to arsenic, cadmium, and lead. If any molybdenum cannot be\nrecycled or reused in the process, it is recommended to sample and\nanalyze for metals, prior to disposal. In addition, a check of the state\nand or local regulations should be performed as some state and/or local\ndisposal requirements are more stringent than Federal requirements.\nMolybdenum is not listed as a hazardous air pollutant under Section\n112 (b) of the CAAA. Fine mineral fibers are listed under this section\nand are described as including manufacturing or processing rock of\naverage diameter 1 micrometer or less. Other metal compounds are\nincluded on the hazardous air pollutant list and any unique chemical\nsubstance containing the other metal compounds on the list are to be\nconsidered in the metal's infrastructure.\nSection XVI:\nMSDS =\nNA=\nTLVs®=\nOther Information:\nMaterial Safety Data Sheet\nNot available\nThreshold limit values for airborne chemicals\nPage 6 of 7\n\n<<<PAGE 11>>>\n\n--\n., ,.. ...\nInterim Final\nIssue Date: February 3, 2006\nBEls®=\nTWA=\nSTEL=\nPEL=\nCAS =\nCFR=\nIDLH =\nNFPA=\nACGIH® =\nNIOSH =\nSARA=\nOSHA=\nCERCLA =\nRCRA=\nTSCA=\nEPA=\nIRIS=\nACGIH =\nRfD =\nATSDR =\nN.O.S. =\nBiological exposure indices\n8 hour, time weighted average for a 40 hour workweek over a lifetime.\nShort-term exposure limit\nPermissible exposure limit\nChemical Abstracts Service\nCode of Federal Regulations\nImmediately Dangerous to Life or Health Concentration Value\nNational Fire Protection Association\nAmerican Conference of Governmental Industrial Hygienists\nNational Institute for Occupational Safety and Health\nSuperfund Amendments and Reauthorization Act\nOccupational Safety and Health Administration\nComprehensive Environmental Response, Compensation, and Liability Act\nResource Conservation and Recovery Act\nToxic Substances Control Act\nU.S. Environmental Protection Agency\nIntegrated Risk Information System\nAmerican Conference of Governmental Industrial Hygienists\nReference Dose\nAgency for Toxic Substances and Disease Registry\nNot Otherwise Specified (means a shipping description from 49 CFR § 172.101\ntable)\nThe information contained herein is based on the data available at the time this MSDS was\nprepared and is believed to be correct.
