Marafeq Qatar is proposed for the construction of SNG Farm to supply Synthetic Natural Gas (“SNG”) to customers including residential and commercial buildings through a city-wide gas distribution network. This SNG Farm shall deliver energy of 200 MWh of SNG and the construction of the farm is planned to complete in two phases.
SCOPE OF WORK
Construction Environment Management Plan has been developed for the proposed construction of SNG Farm at Wadi-2 District of Lusail City. The document will cover all the possible impacts to environment due to the various construction activities as per the project description and also their mitigation and monitoring measures within the site. The various waste generated due to these activities will be accounted and the necessary management plant corresponding to each stage of the project is dealt in accordance with the Marafeq guidelines and Governing laws.
CEMP shall cover effects to environment due to all equipment / items identified for the installation, replacement and demolition and also their management plan. All associated works related to piping, instrumentation, electrical, civil, and structural and loss prevention disciplines shall be also covered under facility.
ENVIRONMENTAL RISK REGISTER
For the development of this CEMP, the Environmental Risk Register (ERR), which was developed as part of the EPIC, was used as guidance. The current controls and additional controls that are identified as part of this register have been compared to the control measures from the Environmental Permit and included as mitigation or management measures. The Environmental Risks identified within the EPIC will be added to the Project Risk Register and updated where required.
The risk assessment matrix includes the consequences for people, asset damage & business losses, environmental effect and reputation impact.
CONSTRUCTION ENVIRONMENTAL MANAGEMENT PLAN
CEMP will detail the minimum impacts & measures that should be achieved for general operations that would fall outside the risk assessment/method statement procedure designed to cover the majority of construction activities. This would cover the following sections detail the key controls that will put in place to address these aspects to minimize the overall environmental impacts of the proposed construction and demolition works.
- Air Quality and Emissions
- Dust and other Emission Controls
- Noise and Vibrations
- Soil Quality
- Water & Wastewater
- Hazardous and Non-Hazardous Waste
- Ecology
- Visual Amenity
- Management of Sensitive areas
WASTE MANAGEMENT PLAN
Waste management is of primary importance in pollution prevention. Whenever waste is properly managed, the adverse impacts on health and/or losses to the environment are minimized and the risk of future liability and claims are reduced.
Petroserv shall ensure that all wastes produced as a result of work are identified as industrial, hazardous or domestic waste and shall be handled and disposed-off in accordance with the Client specifications for Waste Management and all related Qatar regulatory standards related to waste management. Petroserv shall coordinate all waste management activities with Client.
Waste management shall be organized in line with the basic principles defined in relevant Petroserv, such as:
- Use of 3-Rs for waste avoidance and/or reduction, i.e.: reduction of waste production from the design, through construction to commissioning stage of the project, re-use of waste material and recycle and recover of waste material
- When all above mentioned options have been exhausted and a residual waste remains, the optimal treatment process should be identified, depending on the type and quantity of the same.
Waste generated (including wastewater) during construction activities will be identified, quantified, characterized, and waste management practices shall be selected for each waste category and implemented. Disposed quantity of segregated waste shall be monitored and recorded in the Waste Consignment Note.
Dispose Non-Hazardous waste (Cartons & paper waste, plastic waste, construction debris etc.,) to MoECC / Client approved facility. Hazardous liquid waste shall be stored in a secure area with an impervious bunded base that has the capacity to contain 110% of the total volume of stored materials. Dispose the Hazardous waste (used oil / chemical containers, used batteries, used filters, oil soaked cloth etc.,) to the MoECC / Client approved facility by MoECC / Client approved collecting and transporting agencies
CONCLUSION OF THE STUDY
The key findings of the study are:
Main impact sources during site construction activities include
- Emission from construction equipment (such as JCBs, bulldozers & cranes) and vehicles.
- Dust emissions: dust generation from activities including movement of vehicles on unpaved areas, earthmoving operations, material stockpiles
- Fugitive emissions from fuel storage tanks or chemical storage area and Others like painting and insulation activities
- Potential impacts from noise are caused by the construction machines, vehicles and earth moving equipment on-site. Construction activities and particularly use of heavy-duty vehicles will cause noise that will increase the environmental noise levels at the working environment
- Continuous Vibration- Machinery, steady road traffic, continuous construction activity (such as tunnel boring machinery)
- There is no potential risk of groundwater contamination by site activities.
- The project area is located in the residential/ commercial area, where there may be very low disturbance to flora and fauna. There is no trees in and around the site was identified
- Various categories of hazardous & non-hazardous wastes will be arising at different operations of demolition & construction
Mitigation Measures Suggested
- Daily Visual Inspection of dust and black smoke & Monitoring of workplace dust and Verification of road worthiness certificate for vehicles
- Selection of products (painting) shall take into consideration Material Safety Data Sheets (MSDS) contents, in particular choose “low VOC” or “zero VOC” emitting products
- Stockpiles will be kept to a minimum practical size and height and will be constructed with gentle slopes
- Monthly noise monitoring at points near noisy machinery and project boundaries.
- Noise from machinery and equipment used during construction, will not exceed the manufacturer’s specifications.
- Proper Personal Protective Equipment (PPE) will be provided to all personnel
- Vehicle washing prior to service or maintenance should be carried out at a dedicated vehicle washing facility to be constructed by Company or Contractor
- Any wastewater shall be tested for physical parameters like suspended solids and turbidity before discharging them into the authorized discharge points.
- Visual inspection of construction site shall be carried out on regular basis
- Daily and weekly site inspections/ visual monitoring will be carried out by HSE Officer to check for the following:
- Spills/ leaks/ stains on the soil
- Hydraulic oil /fuel storage at pre-identified locations only
- Availability of spill kits in fuel/oil storage area
- Availability of drip trays for storage of all hazardous materials
- Spillage of wastes around the waste storage bins
- Vehicles used for to-and-fro transportation of materials are fully covered and have sufficient free board, so as to avoid any spillage along the transport route
- Contractor shall engage services of the licensed transporter of both non-hazardous and hazardous waste to deliver at the respective QatarEnergy waste treatment / handling centers.
