Implementation of soil stabilization practices and sediment control measures for soil-disturbed <br /> areas of the project site shall be completed, except as provided for below, no later than 20 days <br /> prior to the beginning of the winter season or upon start of applicable construction activities for <br /> projects which begin either during or within 20 days of the winter season. Through the winter <br /> season, the active, soil-disturbed area of the project site shall be no more than five acres. The <br /> Engineer may approve, on a case-by-case basis, expansions of the active, soil-disturbed area <br /> limit. The Contractor shall demonstrate the ability and preparedness to fully deploy soil <br /> stabilization practices and sediment control measures to protect soil-disturbed areas of the <br /> project site before the onset of precipitation. <br /> Throughout the winter season, active soil-disturbed areas of the project site shall be fully <br /> protected at the end of each day with soil stabilization practices and sediment control measures <br /> unless fair weather is predicated through the following work day. The weather forecast shall be <br /> monitored by the Contractor on a daily basis. The National Weather Service forecast shall be <br /> used. If precipitation is predicted prior to the end of the following work day, construction <br /> scheduling shall be modified, as required, and the Contractor shall deploy functioning control <br /> measures prior to the onset of the precipitation. <br /> The Engineer may order the suspension of construction operations which create water pollution <br /> if the Contractor fails to conform to the requirements of this section as determined by the <br /> Engineer. <br /> Collected storm water and groundwater discharged to the City storm water collection system <br /> shall be treated to remove sediment and debris. Sediment removal tanks or basins shall be <br /> constructed that produce a water with no more than 10 mg/I of sediment as measured by <br /> Standard Methods for laboratory analysis. Storm water collection system lines showing <br /> evidence of sediment accumulation due to Contractor work shall be cleaned weekly by flushing <br /> and vacuum truck cleaning to remove sediment to satisfaction of the Engineer. <br /> G. Oil Spill Prevention and Control <br /> The Contractor shall be responsible for prevention, containment, and cleanup of spilling of oil, <br /> fuel, and other petroleum products used in the Contractor's operations. All such prevention, <br /> containment, and cleanup costs shall be borne by the Contractor. The Contractor shall not <br /> discharge oil, fuel, or other petroleum products from equipment or facilities into surrounding <br /> waters or onto adjacent land. <br /> The Contractor shall, at a minimum, take the following measures regarding oil spill prevention, <br /> containment, and cleanup: <br /> Fuel hoses, lubrication equipment, hydraulically operated equipment, oil drums, and other <br /> equipment and facilities shall be inspected regularly for drips, leaks, or signs of damage, and <br /> shall be maintained and stored properly to prevent spills and stored in locked containers to <br /> discourage vandalism. <br /> All land-based oil and products storage tanks shall be diked or located so as to prevent spills <br /> from escaping to the water. Diking and subsoils shall be lined with impervious material to <br /> prevent oil from seeping through the ground and dikes. <br /> All visible oils on land shall be immediately contained using dikes, straw bales, or other <br /> appropriate means and removed using sand, ground clay, sawdust, or other absorbent material, <br /> July 2007 Division III-32 NEI Phase II Water and Sewer <br /> CIP Nos. 7468, 7589, 7590 <br />
