The Mizoram State Roads Project includesaugmentation of the capacityand structural upgradationof selectedroad network in the state. A total of 185.71kmroads will be improved/upgraded,and majormaintenance works will be carriedout on 518.615kmroads, in 2 Phases.The projectwas preparedby the ProjectCo-ordinating Consultants (PCC) 1, on behalf of the PWD, Mizoram.As part of the project preparation,environmental/social assessmentswere carried out, as requiredby the WorldBank and the Governmentof India.
In accordanceto the requirementsof the World Bank,the environmental/socialassessments (and the outputs)had beensubjected to an IndependentReview. The independentreview 2 evaluatedthe EAprocesses and outputsin the projectto verify that (a) the EA had been carriedout withoutany biasor influencefrom the projectproponent and/or the PCC,(b) the EA/SAhad beenable to influenceplanning and design of the project;and (c) the outputs, especiallythe mitigation/managementmeasures identified in the EA/SAprocesses are | adequatefor the project.
The followingdocuments (dated May 2001) were available for the Review: * SectoralEnvironmental Assessment (SEA) for both phasesof the project(prepared at the feasibilitystage of the projectand the PhaseI of the project) * DetailedEnvironmental Assessments (EA) for the work programmein PhaseI of the | Project, * EnvironmentalManagement Plan (EMP) for the improvement/upgradationworks in PhaseI. m . Resettlement & Indigenous People's Development Plan (R&IPDP) for the improvement/upgradationworks in PhaseI. * Environmentaland Social ManagementPlan (ESMP) for the major maintenance worksin PhaseI.
As part of the IndependentReview, gaps and deficienciesin these basedocuments were identified. This reportis partlyan outcomeof the IndependentReview, closing the gaps,as perthe information/datasupplied by the PCCand supplemented by field investigationscarried during the Independent Review. This report took into consideration, the comments/observationsmade by the WorldBank on the basedocuments.
The recommendationsfrom the IndependentReview are incorporatedin the SEAand the other PhaseI EA/SAreports (as well as in the EngineeringDrawings, and the Contract Documents).All reportsnow are modifiedand structuredas per the commentsfrom the IndependentReview.

ENVIRONMENTALMANAGEMENT PLAN
1.1 INTRODUCTION The Governmentof Mizoramis seekingloan under the World Bankloan assistance program(WB Loan no. 4114IN) availablewith the Governmentof India,for upgradation and maintenanceof the state road network. The project envisagesthe major I augmentationof capacityas well as structuralupgradation of roadnetwork in the state of Mizoram.The projectpreparation activities including the projectplanning and design is beingcarried out by the PWD,Government of Mizoram,through Project Co-ordinating Consultants(PCC). A StrategicOptions Study (SOS),covering 3534 km of the state road network,was conductedin October1998-January 1999 with the objectiveof determininginvestment prioritiesfor the road improvementprogram and identifyingroads for the Feasibility I Studies. FeasibilityStudies, including engineeringanalysis and design, social and environmentalscreening and economicevaluation were carried out (completedin January2000). Based on the findingsof thesestudies and discussions between PWD and WorldBank, corridors have been identified as candidatesfor improvement/upgradation and for major maintenanceworks. The corridors that have been identified for I improvementin the two phasesof the projectare listedin Table1.

Damdiai- Sialsukvia Hmuifang approximately30km * Sialsuk- Thenzawl- Buangpui approximately35km The characteristicsof theseroad sections are presentedin table2 below.

The section between Damdiai-Sialsuk(via Hmuifang) passes through five main villages (Lungsai,Thiak, Sumsuih,Hmuifang and Chamring),and is popularly known as the"Five Villages Road". It is an unpavedjeepable road without shoulders and with no proper arrangementsfor drainage. The formation width does not generally exceed4m. With a beautiful scenicview to the west, clean air and a generally salubriousclimate, the route offers potential for developingtourism around the area. There are 18 villages (19 settlements2) falling along the project road. I 1.2.1 PROPOSEDIMPROVEMENTS The improvementsworks envisagedfor the priority road (P1-A) are: | Wideningof the roadto an intermediatelane carriageway(5.5m wide) with sidedrains and shoulders; * Construction/replacement/reconstruction3of bridges and culverts; . Constructionof retainingwalls, breast walls and other slope protection works; a Improvementof the roadgeometry and junctions wherever necessary; and, * Provisionof road signsand other roadfurniture required for makingtravel on these roads safeand comfortable. The improvementsproposed under the project are almost exclusivelyalong the existing alignment, except for some minor realignmentto avoid acquisition of properties and for | improvementof the road geometry. 1 The tOOkmroute lengthhas been reduced to 98.7kmafter design (this is a resultof minorimprovement of horizontal/verticalcurves at severallocations). 2 VillageMaubong has two settlements,Damidiai and Lungsai.

I Revised by Lea Associates 2 October2001 (OriginalDocument by ICT,CES, LBII l MizoramState RoadsProject - PhaseI EnvironmentalManagement Plan for P-IA I 1.3 MAJORFINDINGS OF THE ENVIRONMENTALASSESSMENT As part of the project preparationfor the PhaseI of the project, a detailed 3 environmentalassessment of the P1-Aroute was taken up. The major findingsof the EIAare presented in the followingsections: I 1.3.1 STABILITY OF SLOPES Thewidening of P1corridor is beingcarried out by cuttingthe hillsidefor a majorlength * of the project route. The stabilityof the cut slopesis an issueof concerngiven the immaturegeology of the projectarea. 40 vulnerablelocations with respectto landslides and potentialfor severeerosion identified where adequate protection measures need to be workedout. I 1.3.2 DISPOSAL OF CONSTRUCTIONDEBRIS The cutting activitiesshall generate an earthworkof 1.09million cu.m. The disposalof whichis an issueof concern.Even after filling alongthe very shortrealignment stretches (proposedat 29 locations)has been accountedfor, massivequantities of debris (0.74 millioncu.m) shall have to be disposedof. I 1.3.3 IMPACTON BIO-DIVERSrTY: The roadsideslope all alongthe route P1 supportsa varietyof flora speciesincluding ferns, orchids,bryophytes etc. There exist severalstretches with a high degreeof * biodiversity,referred to as EcologicalIdentity Areas.The proposedwidening may affect such EcologicalIdentity Areasidentified by taking up land with in suchareas in some stretchesif adequateprecautionary measures are not takenup. Movementof machinery can also destroy the rare and endangeredplant species(including the endangered Cyathusspecies or tree fern) at the very edge of the road on the valleyside. Also, the lossof medicinalplants is alsoa potentialnegative impact. I 1.3.4 IMPACTON SENSITIVE SURFACEWATER SOURCES INCLUDING WATERFALLS The corridorpasses close to coupleof swamps/marshylands in additionto severalponds | that would be adverselyimpacted due to the proposedwidening activitiesduring constructionand operationstages. The disposalof debris during constructionand contaminationby roadrun-off during operation onto thesesensitive water resources is a significantnegative impact that nededsto be addressed. In addition, severalstreams from the hillside,form beautifulwaterfalls along the | corridor.Any cutting of the hill face is not only likelyto disturbthe drainageof these streamsbut alsodestroy their visualappeal and denyaccess to the localpeople who tap | thesestreams at present.

Since the pangolinis killedfor its scales and meat, the widenedroad increasesthe risks to its alreadydwindling population. During construction,the poachingby labourerscan pose a significantthreat to the creature. I 1.3.6 RESETTLEMENTAND LOSSOF LIVELIHOOD 58 of the 173affected families are beingdisplaced due to the proposedworks. Though the magnitudeof resettlementis not very high in terms of the familiesto be displaced, the projectneeds to addressthe R&Rand lossof livelihoodissues, as the entireaffected populationis tribal. 1.4 ENVIRONMENTALMANAGEMENT MEASURES PROPOSED A descriptionof the variousmanagement measures during the variousstages of the projectis providedin the followingsections. 1.4.1 PRE-CONSTRUCTIONSTAGE | Duringthe pre-constructionstage, the managementmeasures required will include,the clearance of the vegetation,acquisition of the structures/propertieswithin the proposed CoI, measuresfor protecting/replacingcommunity resources such as hand pumpsand other utilities likelyto be impacted.Their enhancementshall alsobe completedbefore constructionactually starts so that the communitycan start using these while the constructionactivity begins. 1.4.2 CONSTRUCTION STAGE This will be the mostcrucial and activestage for the EnvironmentalManagement Plan. This stage would involvehandling huge quantitiesof earthworkfrom the proposed cutting on the hillside for the accommodationof the proposedcross-section.

I 1.6 INSTITUTIONAL ARRANGEMENTS The MSRPhas been initiated and is being carried out by the Public Works Department. The PWDthrough the Engineer- in - chief, is responsiblefor the effective implementationof the project activities. To carry out the project prioritisation, and to design for the various improvementsthat are proposed, the PWD has appointed international consultants as the Project Co-ordinatingConsultants (PCC) for the project. To effectively oversee the project preparationand to ensurethe timely implementationof the project, a ProjectImplementation Unit (PIU) has been established.The Project Director heads the Project ImplementationUnit (PIU), which at present includes 3 Executive Engineers, looking into the Procurement, Environment and Social Aspects. Each of these executive engineers are assisted by an Assistantengineer for carrying out their responsibilities.The PIUis expectedto play a key role in implementationof the project including the overall control of constructionactivities and implementationof contracts. During the implementationof MSRP,the PIU will be assisted by a SupervisionConsultant I procured through International Competitive Bidding. The SC will assume the role of the Engineer and ensure construction in an environmentally sound manner through their EnvironmentalSpecialist. The monitoring of ConstructionActivities by the PIU will be carried out in conjunction with the Mizoram Pollution Control Board Officials for the pollution component (Air, Water, Noise). For the implementationof R&Ractivities, & local NGOwill be procured. The roles and responsibilities of the various individuals/agencies responsible for the I implementationof the EnvironmentalProvisions have been worked out and detailed terms of referenceworked out for: * EnvironmentalEngineer of the PIU * AssistantEnvironmental Engineer of the PIU * EnvironmentalSpecialist - SupervisionConsultant I . Non-GovernmentalOrganisations - responsible for maintenanceof the plantationon the valleyside * Environmentalspecialist of the QualityAssurance Consultant | EnvironmentalEngineer of the Contractor. I 1.7 TRAINING 1.7.1 NEED FOR TRAINING The EnvironmentalCell of the PIU is alreadyin place. However,the lack of environmentaland social expertiseand sensitivity of the PWD,though has been mitigated to a certainextent due to the exposure to the preparation of the EnvironmentalAssessments for the MSRP,is a matter of concern.This deficiencyshould be mitigated as soon as possibleto enablethe PWD in integrating the social and environmental issues in its day-to-day operation and in I internalising the environmentaland socialissues in the future road developmentprojects.

GeologicalZoning Criteria Zone A: Vertical Rock cuts in relativelyunweathered bedrocks. If exposedsometimes has a potentialfor rock falls. They are of two broad modes: (i) MassiveBlock falls along joints/beddingplane; and, (ii) Laminated,interlaminated thinly bedded, highly weatheredfaces. They cause heaps of small sized weatheredrock elements. This may not pose any serious | blockage. Zone B: Vertical Exposuresat specificJhoras/ Waterfalls at structurallydisturbed points particularlyon the shaded face of the mountain.They typicallyoccur at concave road * bends in between spurs on the sinusoidalroute of a hilly road. These would demand critical examinationof proper protection.In some cases, one may shift the road curve * outwardto provideadditional space for any occasionalrock fall withoutroad blockage. Zone C: Cuts may be on partly weatheredrock and partly on scree materials.The top scree materialsare often cohesivein characterpermitting near vertical cute. * Zone D: At some location cliff formationsare evident. Historicallythese are associated with structuraldisturbances and / or weatheringeffects on the unfavorablysteep planes | of weakness. Zone E: Sloping Hill faces (steep to moderate)exhibits unconsolidated,non-cohesive scree materialshaving the potentialof sliding. Zone F: Cuts in highly laterisedto partiallylaterised hummocky hill top materials. Zone G: Locations specificallyidentified as structurally disturbed,with faulted weak zonesetc. | Notes: Slopeof cut above 5m (or 1Om in caseof no-problemhard rock) is to be smallerthan the slopes suggestedabove, by a degreeadequate for lesseningthe potentialoverburdens; or provideadequate benching. 1 The slopes are recommendedfor a cut height upto 5m in case of laterisedsoil. For hard rockswith tight joint planes,slope of 900 is recommendedfor a height of 1Om. I l I I MitigationMeasures Suggested Dependingon the practical classification,the type of solution is to be chosen. * In the zoneswhere scree materialsare of incoherent character, non - cohesive, with vulnerable geometrical profile, special treatments in the None of known I solutionsand/ or improvisedlocal solutionsare to be adopted.Timber guards to hold or delaythe slides. * Use of Revetment on specific stretches; sometimes turtfier strengthenedwith I Retaining Walls (open pattern), Breast Walls being of Gravity type are often necessary.
