I. INTRODUCTION
The Azerbaijan Water Supply and Sanitation Investment Program is being cofinanced by the Government of Azerbaijan and the Asian Development Bank through a multitranche financing facility (MFF) involving several tranches. The Tranche 1 Nakhcivan subproject of the Investment Program included partial construction of Water Supply and Sewerage (WSS) network of the City and construction of a new Water Treatment Plant (WTP). The Tranche 2 Nakhcivan subproject of the Investment Program, which was signed on 06 June 2012, aims construction of remaining WSS network of the City and construction of a new Waste Water Treatment Plant (WWTP). The Asian Development Bank (ADB) assisted The State Amelioration and Water Management Committee (SAWMC) of Nakhcivan AR for the Water Supply and Sanitation Subproject- Tranche 1 through its financing under Loan 2571-AZE and Subproject-Tranche 2 through its financing under Loan 2842-AZE. Two procurement packages existed under Loan 2571-AZE in Tranche 1 and one procurement package currently exists under Loan 2842- AZE in the Tranche 2:
- Tranche 1 Contract-1 (L-42408-ICB-2.02): Construction of 21.5 km of water network with fire fighting hydrants and house connections, 18.3 km of sewage network with manholes and house connections, and a 10,000 m3 concrete water reservoir. Contract-2 (L-42408-ICB-2.03): Construction of Nakhcivan City water treatment plant with 40,000m3/day capacity
- Tranche 2 Contract-3 (MFF-033-T2-ICB-1.04): Construction of 76.9 km of water network with fire fighting hydrants and house connections, 65.5 km of sewage network with manholes and house connections.
The construction works under Contract-1, was succesfully completed in September 2011. The construction works under Contract-2 started in December 2011, and is expected to end by April 2013. The Contract-3 has signed on 7th of June 2012, and pre-construction works (i.e. mobilization, material stocking etc) have just started. This Report (Bi-Annual Environmental Monitoring Report) is prepared considering the time period from January 2012 to June 2012.

The Project’s Environmental Impact Monitoring and Mitigation is carried out in accordance with the Environmental Management Plans prepared by the PIU / Consultant. The possible construction activities affecting the environment are as follows: (1) Trenching (2) Removal of soil (3) Pipe installation (4) Backfilling and compaction (5) Asphalt/concrete roadway patching paving (6) Concrete works (7) Slope protection and other miscellaneous works. The following items are monitored during the implementation of the project. (1) Noise (2) Water Quality (3) Air Quality (4) Flora - Fauna (5) Waste disposal The water treatment plant site (Contract-2) is owned by SAWMC and is clear of human habitation. In addition, the subproject construction sites under Contract-3 are located in existing roads’ right of way. There are no protected areas, wetlands, mangroves, or estuaries. There is no land acquisition and relocation of people. Trees, vegetation (mostly shrubs and grasses), and animals in the subproject sites are those commonly found in built- up areas. The geological structure of the area is stable and no potential land subsidence is foreseen.
A. Construction activities and Project Progress during previous 6 months
The activities which were carried out by the Contractors in the past 6 months (January 1 to June 30, 2012) comprised mainly of construction of treatment plant building (i.e. pretreatment, pump station, mechanical treatment and membrane treatment zones) and adjacent administration & laboratory building. Other works which were carried out are incidental items comprised of earth grading and installation of water treatment plant raw water drain line of approximately 50 meters. The Works under Contract 3 did not start in field yet. By the end of June 2012, preparation & mobilization period was ongoing. 6
B. Environmental Management Team
An environmental management team exists under the PIU of SAWMC. The team consists of Mr. Ibrahim Mammadov as Manager and Mr. Humbet Bakhshev as Environmental Control Official (ECO). The consultant has also a construction specialist and field inspectors on site for help SAWMC on supervision and monitoring of the Environmental Management Plan. The following works were performed by the environmental management team
● explain the contents of the Environmental Management Plan (EMP) to the contractor, the site staff, the supervisors and any other relevant personnel.
● be on site on daily to supervise environmental actions associated with construction activities.
● monitor and implement the EMP as the most important function.
● ensure that the contractor understands what is to be done to rectify and address any problems that have arisen from the monitoring.

II. ENVIRONMENTAL MONITORING
During the last six months no environmental issues or complaints from the local residents were received. Indeed, there are no residential areas within a radius of 500 m to the water treatment plant site. The access route to the WTP site has is not a common road used by local residents. Only a few farmers who have farmlands on the south side of the WTP site use that road. Random consultations with those farmers showed that construction works do not create any problems or issues for them. The Contractor kept records of contractors safety; environmental considerations of construction sites; air quality, noise and waste management; and public complaints in accordance with Contractors obligations under the Contract. Within this report period, no 7
public complaints or adverse environmental impacts related to the works has been noted or observed.
A. Noise
The Contractor has employed practical means to minimize noise resulting from construction work. Noise was minimized through proper maintenance of equipment and vehicles. All construction tasks were carried out during unrestricted hours (09.00 to 18.00) Monday to Saturday, excluding general holidays All heavy vehicles and mechanical equipments used for the purpose of the Works were fitted with exhaust silencers, which are being maintained in good and efficient working order. No diesel heavy construction equipment are kept running idle for more than five minutes. Machines in intermittent use were being shut down in the intervening period between works or throttled down to a minimum. The Contractor had organized his operations at the start of the project with regard to the positioning of plant and movement of vehicles to minimize noise adjacent to properties. This organization was planned to continue until the end of the project. Special consideration have been provided to protect workers from harmful and long exposures to noise originating from construction machinery such as the wearing of earmuffs for operators. Handling of construction materials were done during daytime.
B. Water Quality
No construction work took place around natural bodies of water like rivers, streams, etc. All works have been undertaken in a manner that will minimize the silting of any body of water and no debris, slash, wood chips, organic debris, soil, petroleum, diesel fuel, oil, grease, ashes, or other substances deleterious to environment was allowed to enter any water bodies. Solid Construction material and spoil stockpiles were covered to reduce material loss and run-off and stockpiles were not located nearer to any water bodies. Natural drainage patterns have been maintained or controlled throughout the entire construction operation to minimize silt release into streams or other water bodies.
C. Air Quality
In cases where dust may occur; the surfaces were sprayed with water using water trucks equipped with sprinklers or any other appropriate means. This procedure was executed to effectively control the excessive spreading of dusts particularly during dry and windy days. 8
30 km/h speed limit was set for movement of heavy construction vehicles on access roads and in the WTP site. All excavation works, and loading/unloading operations were stopped when wind speed exceeded 12 km/s. Dust emission created by concrete plants were collected by their dust collection system or cloth filters to control the excessive dust. All construction activities were executed in such a way that will minimize if not totally eliminate the spreading of dust or any inconvenience and nuisance to nearby communities.
D. Flora and Fauna
The Contractor did not encounter any Flora or Fauna at the WTP site, there is no Flora during the execution of the Works.
E. Waste Disposal
All solid wastes were properly packaged, and disposed at the designated waste disposal site of the City. The site was designated by MENR, and was located 8 km north-west of the City. Waste containers were placed in every construction site and worker camps. These containers were daily collected and disposed lawfully.
