PART 3

EXECUTION

3.1 Dust Control

3.1.1 Control techniques for fugitive dust sources shall involve watering. For arid region and dusty work area, dust control shall include water application with soil binders that is environmental sustainable and non-toxic. The methods utilized shall be cost effective, water conservation, and appropriate for the size and scope of the fugitive dust source. Methods and controls shall not have adverse effects on plant and animal life, ecosystem, and facility air intakes, or contaminate the treated material.

3.1.2 Methods shall be repeated at such intervals as to keep all parts of the disturbed area treated at all times, and the Contractor shall have sufficient competent equipment on the job to accomplish control techniques. Products shall provide a method to reduce dust-related environmental concerns and aid in complying with applicable regulations. Products shall not in any form produce any adverse environmental effects through their use and shall provide an effective, clean, safe control of airborne dust and protection against soil erosion.

3.1.2.1 Preventative Techniques

The reduction of source extent, the incorporation of process modifications, or adjusted work practices, which reduce the amount of dust-generation, are preventative techniques for the control of fugitive dust emissions. These techniques could include, for example, the elimination of mud and dirt carry-out onto paved roads at construction sites.

3.1.2.2 Mitigation Techniques

Mitigation measures entail the periodic removal of dust-producing material. Examples of mitigation control measures include clean-up of spillage on paved or unpaved travel surfaces and clean-up of material spillage at transfer points.

3.2 Materials Handling

The Contractor shall take the following minimum precautions to limit fugitive dust emissions from material handling and transportation to achieve control of dust emissions to the extent practicable:

3.2.1 Stockpiles

The Contractor shall apply water with approved soil binder. Other alternatives shall include laydown top soil with organic matters that are removed from the disturbed area or placing a compounded fiber erosion control blanket to cover material stockpiles and other surfaces which can create airborne dust. BMP perimeter controls around the stockpile shall be placed at least 10 feet away from the toe of stockpiled material.

3.2.2 Transportation

At a minimum, complete covering, maintaining a minimum 12 inch free-board space, and moistening of materials hauled from the construction site is required. The open truck bed creates airborne particulate matter is prohibited. Additional application of water with approved soil binder shall be required if additional controls are considered necessary by the Contracting Officer.

3.2.3 Off-Site Tracking

Dust control shall be performed as the work proceeds to minimize vehicle off-site tracking of sediment and generation of dust. If necessary, temporary paved roadway shall be made to keep vehicles from tracking soils from the construction site. Gravel construction access roadway shall be at least 80 feet long and 30 feet wide for construction site five acres and larger. The access roadway gravel blanket shall be 6-inch minimum in depth with gravel size of 3-inch minimum. The gravel blanket is overlaying on two layers of 6-mil thick geo-textile fabric or a single layer of 10-mil thickness.

Dust generation shall be controlled by water sprinkling. For water conservation, water could be applied with approved soil binder.

3.3 Construction and Demolition

The Contractor shall control dust resulting from demolition and construction activities. No person may cause, suffer, allow, or permit a structure, road, street, alley, or parking area to be constructed, altered, repaired, or demolished, or land to be cleared without taking minimum precautions to achieve control of dust emissions.

3.3.1 Demolition

The amount of dust resulting from demolition shall be controlled to prevent the spread of dust to occupied portions of the construction site and to avoid creation of a nuisance in the surrounding area. The use of water, oil or chemical treatment for control of dust in the demolition of structures, in construction operations, in work performed on a road, parking area, or in the clearing of land is required.

3.3.2 Sandblasting

Adequate methods and enclosure of work areas and debris to prevent airborne particulate matter during sandblasting of structures that contain paint or other similar operations shall be utilized.

3.4 Access Roads and Parking Lots

No person may cause, suffer, allow, or permit any public, industrial, commercial, or private road, street, or alley to be used without taking precautions to achieve control of dust emissions.

In addition to mitigation and control techniques, the removal of soil or other materials shall be periodically performed by mechanical sweepers or their equivalent. The Contractor shall also spot clean dirty roadways and parking lots. These activities shall be performed as deemed necessary. Sand applied for the specific purpose of snow or ice control shall be removed as soon as such control is no longer necessary.

3.4.1 Access Roads

The use of temporary asphalt or uniform gravel covers (as described above for control of Off-Site Tracking) with wheel wash is an acceptable method of dust control for roads leading to and from the area of construction activity.

3.4.2 Parking Lots

Parking surfaces with more than five parking spaces shall be paved. Temporary parking area(s) to be used 30 calendar days or more for the Contractor's equipment or personal vehicles shall be paved with temporary asphalt. Temporary lots used for less than one month may use uniform gravel, if required by Corps Area Office Contracting Officer (AOCO), applying water with approved soil binder may be necessary.

3.5 Control Structures

Activities performed under this Contract shall conform with the specifications described herein along with other technical specifications, particularly Sections 01 35 35 - ENVIRONMENTAL PROTECTION and 01 57 24.00 44 - STORM WATER POLLUTION PREVENTION PLAN.
