INTRODUC1l0N The Ministry of Transport by the Department of Highways planned to widen the primary routes linking the Bangkok Metropolitan Area to each region in order to cope with the rapid increase of the need for transportation. The plan included a total distance of 1,891 kilometers and was completed in 1999. The second phase of widening for further primary routes were proposed.and approved in principle to enhance provincial link within the region in 1995. Th,is plan included a total length of 4,366 kilometers. The mainobjective is to enhance the existing network highways capacity, which consequently. results in road safety improvement and ec.onomic growth stimulation. The widening would generally be undertaken within the existing right of way. Currently, DOH is seeking a World Bank loan for the implementation of the highway-widening project of 5 highway sections, these are:- · Route 4 from Krabi (KM 130+400) to Ao Luk KM 162+200 with a total length of 29.658 kilometres. · Route 24, Amphoe Sikhio Ubon Ratchathani, Section Amphoe Nangrong (KM . 73+283) - Amphoe Prasat (KM 140+000) with a total length of 66.716 kilometres. · Route 201, Amphoe Sikhio - Chaiyaphum, section Amphoe Sikhio (KM 1+400) to Ban Nongbuakhok (KM 52+300), and KM 0+700 - KM 7+948 (Bypass) with a total length of 58.143 kilometres. · Route 331 from Route No.36 Intersection (KM 109+000.000) to Amphoe Sattahip (KM 134+923.537) with a total length of 25.923 kilometers · Route 408 Nakhon Si Thammarat - Songkhla: Section Amphoe Ranot (KM 78+000) to Amphoe Sathing Phra (KM 114+000) with a total length of 36 kilometres. The purpose of the report on environment management plan (EMP) is to identify. potential environmental impact and required management plan to be exeCuted by DOH during the implementation of the proje~t. 2 , j 2. ENVIRONMENTAL MANAGEMENT PLAN To mitigate the potential negative impacts of a highway project, an Environmental M nagement Plan (EMP) is developed typically to identify the mitigation measures to be underta en during construction, and operation stages, including the responsible units. ' I For the highway-widening project, the detailed engineering design hasj been completed at this construction, andt,h,operation. DUring the conceptual and detailed deSign, efforts wer made to . sta,g,e; t,h~r,e,fore e, ,a,cti,~ities.sP,e,~ifie" dinthe E,MPare Ii,mited.,to,thos~, ,',to,be, car,r,ied,~ioutduring I· . . avoid the need for landaequisitidn and compensation, provide adequate safety to road sers, and inform the local public. DOH carried out a formal consultation meeting with local public in January 2009 and a summary of the public consultation report is presented in ch.lipter 8 of the EE report. I The mitigation measures for the environmental impacts have been incprporated into the EMP. DOH will continue to make an effort to ensure that the key mitigation measures that ~n be done during the detailed design stage is incorporated into the final design. Tije EMP requi~ements as minimum environmental requirements will be included into the bidding :!ocument (specifications for highway cdnstructibn). 2.1 NOISE AND VIBRATION Background Noise and vibrationfrom construction activities, and transportation of corstruction materials, and higher traffic volume may impact upon people, property, and other sensitive receptors., ~' Objectives ; , To minimize noise and vibration impacts arising from constr~ction activitie .

Consequently, it is likely to generat~ the sanitary roblems if tne construction camp is not well controlled. Objectives To obtain good sanitary conditions for construction workers. Contractor should plan arid set up Contractor During i Inclu~ed in a construction camp following the criteria construttion cons~ruction I below: period I bud t I · Location of the camps - the area s for locating the, camps should be at least 50 m from waterway and within the service area of electricity and water supply. · Waste management - garbage tank should be provided throughout the construction camp. Garbage tank should be regularly emptied and cleaned. Other disposal method should be approved and in line with local regulations. · Sanitation - safe and clean drinking water should tie provided to all construction workers at all times. Construction camp should be kept clean at all times. Clean restrooms are provided at least 1 restroom per 15 workers. · Management of sewage - wastewater from construction camp will be contained and treated via on site septic tank prior to discharge off. · Safety - all workers should be trained in safety precaution and emergency plan prior to the construction. Adequate first aid kit should be provided. · Removal of the camps and facilities - all camps and facilities will be removed when the construction is completed. The areas will be restored as close as possible to the original conditions. 7 2 Regular inspection of construction camp Contractor, During Included in a should be held to ensure that all Project Engineer construction construction requirements are met. period budget 2.5 SOIL AND EROSION Background Highway construction comprises many activities that are likely cause soil erosion, e.g. excavation, earthworks, and soil aggregate. Large areas of topsoil may be exposed to wind and runoff, which primarily causes soil loss. Soil erosion is, therefore, the major contributor to the build-up of sediment in the water streams.. Objectives · To protect exposedsoil surfaces from erosion To protect and conserve soils. To protect watercourses and downstream water bodies from siltation, sedimentation and water pollutants. DOH should specify additional requirements Contractor, DOH During Included in a for controlling of soil erosion as following: construction construciion · Do not disturb or strip vegetation. If it is period budget necessary to remove the vegetation cover, strip the topsoil immediately after clearing, stockpile and re-use the topsoil to rehabilitate the areas that has been disturbed. · Minimize the area of land disturbed and period of exposure at any points. · Keep stockpiles of construction materials clear of drainage lines. · Protect embankment from runoff and erosion. Embankment protection and control devices include silt fences, mulch or temporary plant covers. · Contain and equip construction materials storage area with drainage system. · Prevent the transport of sediment from material stockpiles. · Stabilize and cover the entrance and exit of construction material storage areas by temporary vegetation or gravel. .....-. -,_______........,. _________----....... l-"'--·_· ----"""""...,-,~,- "'ijl~_' ------~-r---~-. 8 areas prior to any site disturbance. · Restrict vehicle movement over cleared areas. 2 All drainage structures and erosion controls Contractor, During Included in a should be monitored and repaired Highway District construction construction· periodically. and o~eration and Phase 3 Sediment structures and drainage paths Highway District Operation should be maintained through regular Phasti cleaning and flushing out of sediment and' litter, in order to retain maximum effectiveness 4 Grassing cover should be maintained over Highway District side slope to prevent soil erosion from runoff Ph during rainy season. 2.6 TRANSPORTATION Background Highway construction will result' in a noticeable increase in the volume of traffic by transportation of construction materials! equipment. The increased traffic could reduce the level of road safety if not properly managed in particular to on site workers, road users, and surrounding communities. Road accidents may occur that could result in inju~ies, deaths, iand other I environmental damage. Objectives To minimi.ze impacts from potentially increased traffic volum~ on .Iocal To ensure the safety of construction personnel and the pu Contractor construction plan, activities, and appropriate alternative roads, in advance. 2. The contractor has to strictly fullow the traffic Contractor management plan as described beloW: · The contractor constructs first stage at area outside edge of existing roadway. construction 9 Interruptions to traffic flow on existing roadway are not allowed. If the contractor requires area on shoulder of existing roadway for construction, permission has to be obtained from the project engineer. · . The contractor shall provide preventive measures against accident and inconvenience to the road user. The measure shall include installation of traffic sign, marking, .signal, lighting, and other incidental conforming to DOH. · After complete the first stage construction up tO,binder course layer, this layer will be opened to traffic serve. Then, the second stag~ construction will be commenced. · No space allowed on first stage construction area for second stage construction. · Afterpnishing the second stage construction with all incidentals, all traffic will be diverted to use these areas, and then wearing course layer shall be placed in first stage construction area with all incidentals. · Lane blocking at any place and any time are not allowed. Except the necessary area, blocking may be allowed at night time. During blocking time, both direction of traffic flow shall be maintained at least one lane and preventiye measures against accident shall be provided. 3.

Phase' 2.7 SOCIO-ECONOMIC Background Socio-economic impacts can consist of positive and negative impacts to human life ithin local communities. Economic impacts occurred during construction such as increase local income or loss of business opportunities. Sodal impacts are the other impacts to social syste s such as restriction in access to transport, recreation and work. noise and otherenvironmenf I impacts affectingthe community. ?ocial impacts can be managed through a publi~ involvement process. Objectives To maintain existing social systems and networking during cc;>nstruction. , · To manage community issues proactively and ensure stakl3holdersatisflilction with the public involvement process. To ensure that construction schedule is not delayed du~ to social or economic issues. I 1. Local public will be informed prior the Contractor Begihring of commencement of civil work regarding construction temporary inconveniences during the period construction period. 2.

However, some plants will be rem~:>ved and.can result in the loss of vegetation from that site. Any loss of threatened vegetation wilrreduce the chances for the long term survival of that species. Objectives · To ensure that maximum vegetation is retained on-site. To ensure that any rare species are not damaged by the construction activities. The contractor has to follow the requirements as Contractor ' During Included in a described below; construction construction period budget · Avoid disturbing the vegetation in areas outside the construction zone. · Contact the Forest Industry Organization before removing teaks from the construction areas (if any). · Transplanting shall be considered as much as possible. 12 I 3. ENVIRONMENTAL MONITORING PROGRAM DOH will bear full responsibility for ensuring that the project complies ~ith best environmental practices and meets the mitigation and monitoring requirements as described in this port. To ensure highly effective EMP, a monitoring program has been dev~loped comp ising two , I elements: environmental quality monitoring and monitoring of conttactor's environmental performan'ce. : I' . i, ; I , '(a) Environmental Quality can be assessed bycommon monito~ing paramete such as :rota1 suspend~d,' part~cl,e, ,(TSP), .an,d noise and, vibratio~, level. GiV,en thee~ent of e,nv ro~me,ntal f ,Impacts aSsociated With the proJect, however, the environmental qua will no! be s gmficantly deteriorated. The impacts of highway widening are minor in nature short in d, ration. In 'addition, the results of public consultation indicated that p.ublicrath:er concern ~bout their convenience and safety as they rarely experience the severe irnpadts on dust, ~oise, and vibration nuisance. Furthermore, Environmental Management Plan has b~en developed to ensure the Contractor's good environmental practices. However, the Contractor will be rqUired to conduct the environmental quality monitoring as advised by the Engineer or the E vironment Group. This could be a result from periodic monitoring of the Contractor's env ronmental performance if any major deficiency of good practices is observed. I , , , (b) The Contractor's Environmental Performance is the crucial factor conlibuting to environmental quality. Therefore, ,a constructive monitoring on the c~ntractor's environmental performance has been set up. Environmental Management Monitoring Checklist {see Annex I) has been developed for periodic monitoring by the DOH's Engineers, and DOH's EfVironment Group. This checklist comprises five forms: project description, monitbring log she t, monthly check, and non-compliance and corrective and preventive action. I ,I " I : Form 1: Project description includes the detailed information of the proje:ct title, location, Contract period, DOH's Engineers, and The Contractor. This form will be completbd by DOH's ~ngineer at , , , the first monitoring and maintained throughout the period of contract. , Form 2: Monitoring log sheet records the monitoring date and present ~he aCknOwle~gement of the Contractor regarding the monitoring results. DOH's Engineer will filII this format the end of each monitOring to record the monitoring date and Contractor's acknowl~dgement. Form 3: Monthly check covers all common construction activities, which could result in adverse environmental impacts. The Engineer will monitor ,the Contractor's en~ironmental m~nagement against issues included in this form every ,month. ' Form 4: Non-compliance and corrective and preventive action is a record of non-compliance identified from the periodic monitoring. This is to ensure that effectiv~ action is established to rectify any ,improper env,ironmental manag,ement, or,practices. At the end,: ofeach molitoring" the Engineer will discuss with ,the Contractor's Project Engineer regarding poor en ironmental practiced being observed. The Contractor will be required to set up dorrective and preventive I action plan, set the target date, and agree with the Engineer. The E~gineer will fo ,lOW up the action plan when it is due. Close up can be either complete or incory,plete depending on the correction and improvement undertaken by the Contractor. Incomplete close up ~ill' result in another action plan and the process will be repeated until the action plani is completely closed. 13 DOH's Engineers will monitor the Contractor's environmental performance at leas.t once a month. The Contractor w.iII be required to complete Non-compliance and corrective and preventive action form if inappropriate practices are observed. A monthly report, which contains completed monitoring checklist, summary of findings, and corrective and preventive actions will be submitted to DOH's Environment Group. DOH's Environment Group will conduct biannual monitoring (audit) on the Contractor's environmental performance at least twice a year (during dry and wet season). TheContractor and DOH~s Engineers will be present throughout the monitoring. If any major. deficiencies in good environmental practices are observed during monitoring, the Contractor will be responsible for the monitoring:of environmental quality (dust, noise, vibration, w'ater qualitY,\E!tc)as advised by the Engineer in consultation with the Environment Group.The results ofenvironmental monitoring will be compared with relevant environmental standards, issued by enforcing~uthorities,.e~g. ~the " ' ,:', . , ' " ' Pollution Control Department. Appropriate correction .· will be·. carried out accordingly. The summary of monitoring results wil\1 be sent to the World Bank for.informatioh. . l' ' , , ,"I," 4. PUBLIC CONSULTATION DOH will make appropriate arrangement to inform local PFlople and local communities about the project, including final design, proposed mitigation plan and construction schedule prior to road construction. During construction, construction plan will also be informed to local people and communities periodically. ~~------~----.-----.-.*---.--.------------------------~---------- 14 .
