PS 3 – Resource Efficiency and Pollution Prevention
The operational phase of the project is not expected to generate significant amounts of direct emissions, waste or effluents, considering it mainly involves container off-loading, on-loading, handling, transport and storage within the port premises and managed consistently with the respective local regulations and IFC PSs and WBG general and sector-specific EHS Guidelines. Electricity and water are sourced from the grid, back-up diesel generators are available. MIP is undertaking efficiency measures to reduce resource consumption i.e., electric cranes, LED lightning.
Total GHG emissions (Scope 1 and Scope 2) associated with this project are estimated to be around 11,000 tons of CO2 eq. The key climate risks for the project are identified as sea level rise and extreme heat (under RCP4.5 and 8.5 climate change scenarios). Accordingly, the berth was designed with an allowance of 0.34 m for sea level rise considering the predicted increase in mean sea level between 0.43 m and 0.84 m by 2100 (which is considered a long-term impact). MIP has a stormwater collection and drainage system for the existing facilities. As part of the project, MIP will construct an effective drainage system for the new buildings and other facilities. Going forward, as part of its ESMS, MIP will integrate climate risks to its risk screening & assessment procedure and management plans for identifying and addressing any climate-related risks for its operations including OHS related risks and flood risk management as per ESAP# 6.
The construction phase will generate short-term impacts related to the air quality, noise, seawater quality and sediment. In accordance with the local EIA, air and noise emissions, dredging and marine impact assessment, and the respective management plans. The EPC’s CESMP will include specific requirements to address those issues.
During the construction, the primary air emission sources (PM10, PM2.5) will be associated with dredging activities, vehicle movements (transport of materials and equipment) and earthworks, which will be controlled through implementation of the CESMP to be developed per ESAP#2. Air emissions modelling results showed no exceedance of WHO ambient air quality limit values. MIP will continue monitoring air emissions at its premises as per the existing ESMS, and, if exceedance occurs, MIP will take necessary mitigation measures i.e., use of shore power.
Container loading/unloading, vehicular traffic and cargo handling are the main sources of operational noise pollution. According to the baseline measurement program, noise levels are within the national limits and slightly exceed WBG EHS Guideline limit values for some receptors. Noise modelling studies indicate slight exceedance for one recreational receptor during both construction and operation and only at night. Based on the observations during the site visits and information provided by MIP, no significant adverse impact is expected as the recreational site is not actively used during the night. As per ESAP#7, MIP will undertake a study to identify and characterize the noise pollution within its premises based on which it will implement a Noise Management and Monitoring Plan in line with national regulations, GIIP and the WBG EHS Guidelines. The plan will include a noise monitoring program to periodically measure the noise levels in the sensitive receptors. MIP will provide trainings to lashers, crane operators and any other relevant staff to limit noise emissions while conducting their respective operations.
Within the scope of the project, around 3.3 million m3 capital dredging is expected to be extracted. All dredging works including removal, handling and disposal of the seabed material shall be conducted in compliance with the “Dredging of Marine and Inland Waters Regulation” issued by Turkish Ministry of Transport. MIP carried out a sediment measurement campaign for to be dredged area including inner basin adjoining to the berth, access channel and the disposal site and compared the sample test results carried out by an accredited laboratory with the international (i.e., Australian, Canadian and European countries) and Turkish guideline values. Test results confirm its formation and suitability for the dredging offshore.
The dredging will be performed in the same area that was dredged during the construction of the existing berth in 2013. The monitoring measurement results from the previous dredging activities showed no adverse impacts to the marine environment in the dredging, dumping site and surrounding. The baseline measurement results level for seawater quality at the port area and disposal area indicate no existing pollution. As part of this project, dredging of access channel up to 18.5 m, container berth docking area and turning basin up to 17.6 m and the west docking area up to 10 m will be required to allow for the safe entrance of larger vessels into the port. The container yard area will be reclaimed up to 3 m above sea level along the quay wall length of 880 m. The dredging works will generate about 3.3 million m3 of material and a total area of around 177,000 m2 will be reclaimed. While the option to reuse the dredged material for reclamation was evaluated, due to the poor engineering characteristics, it was found not suitable as filling material. Analytical testing including heavy metals and polychlorinated biphenyls confirmed that the dredged material will not further contaminate the water column and disposal area sediment. Based on the results and multiple exchange with an independent expert, it was concluded that the dredged material is suitable for disposing off-site to Ministry of Environment and Urbanization designated offshore disposal area located around 5 km from the shore at a water depth of between 42-54 m. The disposal site has enough capacity and similar characteristics with to be dredged material.
As specified in ESAP#2, contractor will develop a dredging management and monitoring plan (DMMP) which will spell out the technical specifications considering the potential impacts identified especially with regard to protecting biodiversity with the guidance provided in the biodiversity risk assessment and management plan and other related management plans during the transport of the material in line with the permit conditions, IFC PSs and international good practices. The key mitigation actions while undertaking dredging activities will include but not limited to: a. combining trail suction (TSH) barge and cutter suction dredger for to pre-cut soil that cannot be dredged by TSH; b. the dredged material will be hauled to the disposal area with a leakproof split hopper barge; c. the dredging activities in the approach channel and any area outside of breakwaters will not be undertaken between 1st of April and 30th of September during the breeding season of most fishes and migratory activities of marine turtles; d. the contractor will implement relevant controls to limit turbidity form the dredging activities; e. Turtle deflector (e.g. tickler chains) or similar devices will be used in case turtles are in the vicinity of dredger trailer and there will be a dedicated marine turtles observer staff onboard. Additionally, contractor’s DMMP will comprise of required monitoring and control measures including plume and water quality, biodiversity, navigational safety and specific targeted community engagement regarding dredgers.
The bulk of the wastes managed by MIP as port operator are those generated by ships and from its own operations. MIP has a license to store wastes on site on a temporary basis, after which the wastes are removed by licensed waste management contractors. Solid waste (e.g., plastics, scrap metals, wastepaper) and hazardous wastes (e.g., drums, batteries) are segregated effectively at the site and collected by licensed third-party contractors. Secondary containments were implemented to all waste oil or hazardous materials storage drums/containers.
Bilge water from the vessels is collected and treated on-site. The sludge is disposed by a licensed third-party contractor while the treated wastewater is discharged to the municipality sewage network for further treatment. Sanitary wastewater collected from the vessels by trucks and sanitary wastewater from the office buildings is discharged to the municipality sewage network. Wastewater sourced from canteen and wastewater generated in the workshops are pre-treated on-site (e.g., grease, oil, suspended solids) and discharged to the network for further treatment. Drainage systems are cleaned regularly. As part of the expansion project, the capacity of the waste treatment facility to collect wastewater from the vessels was increased by adding two new sludge tanks (35m3 each). Storm water drainage is collected in catch basins with oil-water separator. The water quality is monitored by yard inspectors and storm water runoff free of contamination is discharged to the sea.
Hazardous Materials Handling
Hazardous materials use during construction phase of the project will be limited. During operations, Hazardous materials are stored in the port’s maintenance yard and typically include oils, diesel fuel and degreasing agents used in maintenance activities, with secondary containment, and material safety data sheets (“MSDS”) posted nearby. Hazardous and flammable cargos, such as industrial chemicals, are stored in an open area within the port and handled in accordance with International Maritime Dangerous Goods Code (IMDG). Proper firefighting equipment is available. Refueling for the ships is provided by fuel companies under the supervision of Mersin Port Authority.
