26 action. If the CONTRACTOR fails or refuses to comply promptly, the OWNER may issue an order stopping all or part of the work until satisfactory corrective action has been taken. Stop Work orders to achieve compliance with environmental regulations shall not be justification for extension of time or for any costs or damages to the CONTRACTOR. D. CONSTRUCTION IMPACT ON THE ENVIRONMENT Construction activities and methods shall minimally impact the environment surrounding the project, including dust, air and noise pollution and prevention of entrance or accidental spillage of solid matter, contaminants, debris and other pollutants and wastes into any water course, and/or any underground water sources. Such wastes include, but are not limited to, eroded soils, refuse, garbage, cement, concrete, sanitary waste, industrial waste, oil and other petroleum products, chemicals, mineral salts and spirits, and thermal pollution. 1.4 RUBBISH CONTROL Maintain the site of the Work in a neat and clean condition, free from any accumulation of rubbish. At regular intervals, collect and dispose of all rubbish and waste materials. Provide trash bins or otherwise control the collection, storage and transport of rubbish and waste materials so as to preclude blowing of loose trash due to high winds. Furnish, at a minimum, one covered dumpster at the project site. The dumpster shall be emptied at least once per week, or more frequently, whenever the dumpster is full. Keep roadways free from dirt, rubbish, and obstructions during construction operations. 1.5 CHEMICALS AND PETROLEUM BASED PRODUCTS A. APPROVED CHEMICALS All chemicals used during project construction or furnished for project operation shall show approval of either the U.S. Environmental Protection Agency or the U.S. Department of Agriculture. Use of all such chemicals and disposal of residues shall be in strict accordance with the printed instructions of the manufacturer. Submit Material Safety Data Sheets (MSDS) for any hazardous material proposed to be used in the construction of the Work. Follow the information on the MSDS to assure safe use, handling, storage and environmentally acceptable disposal of the material used. B. FLAMMABLE AND COMBUSTIBLE MATERIALS Storage and handling of flammable and combustible materials and provisions for fire prevention shall be in accordance with the latest applicable OSHA requirements. C. CHEMICAL STORAGE AND HANDLING All chemicals and petroleum based products stored in drums or tanks on site shall be provided with secondary containment facilities meeting Federal, State, and local laws, ordinances, regulations and permit conditions. All spigots shall be positioned so that secondary containment ENVIRONMENTAL PROTECTION DECEMBER

27 facilities catch any drips. All-weather temporary roofs or covers shall be provided over such containers and secondary containment facilities to the satisfaction of the ENGINEER. D. DISPOSAL OF WASTE PETROLEUM PRODUCTS All waste petroleum based products shall be contained in sealed containers and disposed of at approved recycling facilities, and, if not recyclable, shall be disposed of at an approved dump site. Any spills shall be promptly cleaned up and waste, spillage, and contaminated materials disposed of at an approved dump site. Proof that a spill is cleaned up adequately shall be done to the satisfaction of the OWNER, the ENGINEER, and appropriate regulatory authority. 1.7 NOISE CONTROL Maintain noise below levels proscribed by the Occupational Safety and Health Administration. All construction equipment operated at the site shall be equipped with manufacturer's standard noise control devices such as mufflers, lagging, and/or engine enclosures which normally achieve compliance with noise limits. Inspect construction equipment regularly to ensure proper maintenance and presence of noise control devices such as mufflers and shrouding. Monitor construction equipment noise to ensure compliance to the required noise limits. Maximize the distance between noisy construction activities and noise-sensitive land uses. Noisy temporary equipment, such as pumps and air compressors, shall be located on the construction boundary most distant from nearby occupied structures. 1.8 WELDING Notify all occupants of nearby buildings prior to welding activities within their visual range. Safeguard construction workers and all others from welding activities. 1.9 CLEANUP AND DISPOSAL OF EXCESS MATERIAL Keep the site of operations in a clean and neat condition. Dispose of all construction residue at an appropriate disposal site or facility. Remove and haul away any surplus excavated material, broken pavement, lumber, equipment, temporary structures and any other refuse remaining from the construction operations. Leave the entire site of the work in a neat and orderly condition. Burning at the project site for the disposal of refuse and debris will not be permitted PROTECTION OF WATER RESOURCES A. TREATMENT OF CONTAMINATED WATER Protect all streams, wetlands, and groundwater resources from environmental pollution resulting from operation of equipment, materials storage, or other construction activity in or near such water resources. Water used for washing or processing, from dewatering operations, or that contains oils or sediments, shall not be discharged directly to any waters of the State of Colorado or indirectly through any storm sewer or temporary drainage channel. Contaminated or polluted waters shall be diverted through a settling basin, filter, or other treatment process acceptable to ENVIRONMENTAL PROTECTION DECEMBER

28 the Colorado Department of Public Health and Environment prior to discharge off-site. Place all erosion control measures in an area prior to any construction activity in that area. B. EROSION CONTROL Provide positive means of erosion control such as shallow ditches around construction to carry off surface water. Erosion control measures, such as silt basins, hay check dams, mulching, jute netting and other equivalent techniques, shall be used as appropriate. Offsite surface water shall be diverted around the site, to a downstream channel ahead of silt barriers. Flow of surface water into excavation areas shall be prevented. Ditches around construction area shall also be used to carry away water resulting from dewatering of excavated areas. At the completion of the work, ditches shall be backfilled and the ground surface restored to its original condition PROTECTION OF LAND RESOURCES A. GENERAL Land resources within the project boundaries and outside the limits of permanent work shall be restored to a condition, after completion of construction that will appear to be natural and not detract from the appearance of the project. Confine all construction activities to areas shown on the Drawings. Protect monuments and markers with fences or barricades before beginning operations near them. B. PROTECTION OF VEGETATION Outside of areas requiring earthwork for the construction of the new facilities, maintain and protect trees, shrubs, and other vegetation. Do not remove or cut trees or shrubs without prior approval. Where trees may be defaced, bruised, injured, or otherwise damaged by construction equipment or operations, protect such trees by placing fences or barricades around them. Restore any trees or other landscape feature scarred or damaged by construction equipment or operations as nearly as possible to its original condition. Trees that are to remain, either within or outside established clearing limits, that are damaged by the CONTRACTOR and are beyond saving in the opinion of the ENGINEER, shall be immediately removed or replaced PROTECTION OF AIR QUALITY A. DUST CONTROL Dust control shall be performed as the work proceeds and whenever a dust nuisance or hazard occurs, as determined by the OWNER. Control fugitive dust from all excavations, embankments, stockpiles, access roads, waste areas, and borrow areas by sprinkling with water or other similar methods.
