PCS/Waste Management Method Used

Operational measures, such as limiting engine idling tome and shutting down equipment when not in use;

Remarks

These measures will be applied in different project phases as may be applicable

Regular preventive maintenance to prevent emissions increases due to engine problems Use of low-sulfur and low aromatic fuel meeting PCAA standards for  motor vehicle Diesel fuel; Use of low-emitting Diesel engines meeting federal emissions standards for construction equipment if available; Use either water application or chemical dust suppressant application to control dust emissions from unpaved surface travel an unpaved parking areas; Use vacuum sweeping and/or water flushing of paved road surface to remove buildup of loose material to control dust emissions from travel on the paved access road (including adjacent public streets impacted by construction activities) and paved parking areas Cover all trucks hauling soil, sand, and other loose materials, or require all trucks to maintain at least two feet of freeboard; Limit traffic speeds on unpaved surfaces to 25 mph; Install sandbags or other erosion control measures to prevent silt runoff to roadways; Watershed Management will be implemented Re-plant vegetation in disturbed areas within a reasonable period of time; within a 10-hectare area surrounding the source during the operation and maintenance phase of  the project  As needed, use gravel pads along with wheel washers or wash tires of all trucks exiting construction site that carry track-out dirt from unpaved surfaces; Mitigate fugitive dust emissions from wind erosion of areas disturbed from construction activities (including storage piles) by application of either  water or chemical dust suppresant and/or use of wind breaks Liquid allow natural drainage of flood water or water used for hydrotesting and disinfection of source box, ground tank and pipelines by land application allow settling to occur after maintenance activity has been performed as natural treatment for turbidity cement preparation will be made some distance from the creek to avoid contamination of water body and to allow natural treatment of the creek before resumption of domestic use monitoring of water quality by taking sample for analysis at the laboratory or conducting on-site testing before and after the hydrotesting and disinfection of pipes Solid

Instruct employees and subcontractors on identification of solid waste and hazardous waste and proper disposal procedures, and Wherever possible, minimize production of solid waste materials. Dumpsters of sufficient size and number will be provided to contain the solid waste generated by the project and properly serviced regularly maintain clean construction sites and minimize the exposure of waste to storm water. Properly labelled trash receptacles will be provided in the materials yard and at locations where workers congregate for lunch and break periods. These containers will be transported at the Material Recovery Facility in the area. Only watertight dumpsters will be used on-site. Solid waste storage areas should be located at least 50-feet from drainage facilities and watercourses and should not be located in areas prone to flooding or ponding. the CRM and should be removed from the site every two weeks or  directed by the Engineer or CRM. Segregate potentially hazardous waste from non-hazardous construction site waste. Make sure the toxic liquid wastes (e.g., used oils, solvents, and paints) and chemical (e.g., acids, pesticides, additives, curing compounds) are not disposed of in dumpsters designated for construction debris. For disposal of hazardous waste, see section on Hazardous Waste

hydrotesting and disinfection works will be done after construction of source collection box and concrete ground tank, and after pipelaying works has been completed

Management. Have hazardous waste hauled to an appropriate disposal and/or recycling facility. Salvage or recycle useful vegetation debris, packaging and/or surplus building materials when practical. For example, trees and shrubs from land clearing can be converted into wood chips, then used as mulch on graded areas. Wood pallets, cardboard boxes, and construction scraps can also be recycled. Noise

workers will be advised to put on ear plugs especially operators of the noise generating equipments noise barriers will be constructed in areas where a community may be located

project area is mostly composed of open spaces construction activities in the timberland area area are reduced to the receiving point since the vegetation serve as natural noise barriers
