1 LEHDER Environmental Services Limited has attempted to obtain an updated MSDS. No update is available for the reason identified below: Manufacturer/supplier confirms this to be an uncontrolled product, and as such, three year updates are not required by law. Manufacturer/supplier confirms that this is the most recent MSDS available. Manufacturer/supplier has not responded to our request for an updated MSDS prior to project completion schedule. MSDS now available for individual product lines. LEHDER requires identification of specific product. Manufacturer/supplier will not send MSDS to third party.

2 Material Safety Data Sheet Coal: Sub Bituminous Revised ( ) 6 pages Section 1: CHEMICAL PRODUCT and COMPANY IDENTIFICATION 1.1 Product Name Coal: Sub Bituminous C Chemical Family Sub Bituminous Coal, naturally occurring mineral Chemical Family Carbon 1.2 Manufacturer Cloud Peak Energy Resources LLC 505 South Gillette Avenue Gillette, Wyoming (307) Emergency Contact (307) (Cloud Peak Energy Resources) (800) (CHEMTREC) Section 2: COMPOSITION, INFORMATION ON INGREDIENTS 2.1 Chemical Ingredients C.A.S. Number % by Weight Coal Carbon: Fixed % Volatiles Not Applicable % Moisture Not Applicable % Ash Not Applicable 3 9 % Sulfur % Silica % Coal composition (% by weight) varies among different deposits of coal. Section 3: HAZARDS IDENTIFICATION 3.1 Physical Hazards: Combustible black dust which may release CO x, SO x, or Methane upon combustion. Difficult to extinguish when burning.

3 3.2 Health Effects Inhalation: Avoid inhalation of dust Acute Effects: May cause irritation to respiratory system due to inhalation of high dust levels well above the 8-hour occupational exposure limits. Chronic Effects: Repeated exposure over years may cause: Coal Worker s Pneumoconiosis or Silicosis. Ingestion: Relatively harmless Skin Absorption: Unlikely to occur Eye Contact: Contact with eyes by production of dust may cause irritation Skin Contact: Prolonged or repeated contact may cause irritation due to abrasiveness Carcinogenicity: Coal contains small amounts of Silica (Quartz). The International Agency on Research for Cancer (IARC) has classified Silica (Quartz) as a Group 1, known human carcinogen. However, IARC have also concluded that there was inadequate evidence in humans and in experimental animals for the carcinogenicity of coal dust, and that coal dust cannot be classified as to it s carcinogenicity to humans. Section 4: FIRE & EXPLOSION HAZARD DATA 4.1 Flammable Properties Flashpoint: Not Applicable (Solid) Flammable Limits: LEL: N/A (Solid) UEL: N/A (Solid) 4.2 NFPA Rating Health 0 Flammability 0 Reactivity Extinguishing Media: Water Spray (Fog), Foam, CO Fire & Explosion Hazards: Combustible Solid; Slightly explosive when exposed to flame. Avoid dust generation to minimize explosive hazard. Eliminate ignition sources in areas of dust generation and accumulation to avoid explosion. 4.5 Combustion Hazards: May produce CO x, SO x, and Methane upon combustion 4.6 Fire Fighting Equipment: Wear pressure demand Self-Contained Breathing Apparatus (SCBA) and full protective gear.

4 Section 5: ACCIDENTAL RELEASE MEASURES 5.1 Spill Cleanup Measures: Spray lightly with water to avoid creating dust and sweep/shovel into suitable container. 5.2 Personal Precautions Wear appropriate respiratory protection for dust generation above occupational exposure limits. Refer to Section Environmental Precautions Coal is not classified as a hazardous waste. Dispose of in an approved landfill or incinerate according to national and local standards. Section 6: HANDLING AND STORAGE 6.1 Handling and Storage Prevent exposure to high temperatures and flames Precautions Prevent exposures to strong oxidizers 6.2 Hygienic Practices Avoid creating dust. Wash exposed skin and clothes daily. Section 7: FIRST AID MEASURES 7.1 Inhalation If irritation or discomfort exists, remove the exposed individual to fresh air. 7.2 Skin Not hazardous Wash exposed skin for hygienic purposes. 7.3 Ingestion Not hazardous Avoid ingestion may cause irritability of digestive system. 7.4 Eyes If irritation or discomfort exists, flush eyes lightly with water to Remove dusts. Section 8: STABILITY & REACTIVITY 8.1 Chemical Stability Stable 8.2 Hazardous Polymerization Will not occur 8.3 Hazardous Decomposition Products Releases carbon monoxide, carbon dioxide sulfur monoxide, sulfur dioxide and methane upon combustion. 8.4 Incompatibility Strong Oxidizers; May cause fires 8.5 Conditions to Avoid Contact with strong oxidizers, especially when heated. High temperatures or flame.

For levels above the listed occupational exposure limits wear an appropriate NIOSH approved respirator Personal Protective Equipment: Gloves: Protective Clothing: Eye/Face Protection: None required None required: Confine work clothing to workplace and wash daily None required 10.3 Occupational Exposure Limits Chemical OSHA PEL TWA ACGIH TLV TWA NIOSH REL Coal Dust (as respirable fractio < 5% SiO 2 (Silica) 2.4 mg/m mg/m 3 None Established Coal Dust (as respirable fractio > 5% SiO 2 (Silica) 10 mg/m 3 % SiO mg/m 3 None Established 10.4 Engineering Controls: Use sufficient ventilation to maintain exposure levels below occupational exposure limits

6 Section 11: TOXICOLOGICAL INFORMATION 11.1 Routes of Exposure Inhalation 11.2 Medical Conditions Aggravated None expected; may aggravate pre-existing respiratory conditions such as bronchitis or asthma due to nuisance dust nature Carcinogenicity Coal contains small amounts of Silica (Quartz). The International Agency on Research for Cancer (IARC) has classified Silica (Quartz) as a Group 1, known human carcinogen. However, IARC have also concluded that there was inadequate evidence in humans and in experimental animals for the carcinogenicity of coal dust, and that coal dust cannot be classified as to it s carcinogenicity to humans Teratogenicity Not Available 11.5 Mutagenicity Not Available 11.6 Sensitization Not Available Section 12: REGULATORY INFORMATION OSHA Hazard Communication Rule Toxic Substance Control Act (TSCA): Some constituents in this product are considered to be hazardous and should be included in the employer s hazard communication program.
