Physical Environment
Chongqing is located in the southwestern part of China's inland and the upper reaches of the Yangtze River
Nan’an District is in the main city of Chongqing, is located on the South Bank of the Yangtze River in Chongqing，between E106°3′14″~ 106°47′2″ and N29°27′2″~29°37′2″
Jiulongpo District is in the west of Chongqing, between E106°14′52″~ 106°32′55″andN29°15′29″~29°33′44″.
Nan’an District, situated in the parallel ridge-valley of East Sichuan, showcases a unique geological structure characterized by alternating anticlines and synclines Key formations include the Mingyuexia anticline, Guangfusi syncline, and Tongluoxia anticline, leading to a diverse landscape of mountains, valleys, hills, flatlands, and rivers This varied topography creates a distinctive geomorphology in the region.
Figure 4-1 Nan’an District topographic map
Jiulongpo District is part of the southern extension of the Huayingshan ribbon fold, characterized by its unique geological formations The region features an anticline that creates mountains and a syncline that forms valleys, resulting in middle and low mountains on the anticlinal structure The landscape predominantly consists of open flanks and rounded middle to low hills, as illustrated in Figure 4-2.
Figure 4-2 Jiulongpo District topographic map
Nan’an and Jiulongpo Districts, situated in the Sichuan Basin, experience a subtropical monsoon humid climate characterized by abundant rainfall and warmth The region has a long frost-free period, with cold early springs, hot summers, frequent autumn rains, and foggy winters The annual average temperatures range from 16℃ to 18℃, making it a unique climate zone within the basin.
Surface water resources primarily consist of transit water from rivers and streams, with an annual average of 344.75 billion m³ The Yangtze River is the dominant contributor, while three smaller rivers collectively provide 40.48 million m³, contributing more than other surface runoff sources in the region.
The Yangtze River originates in the southern region and flows east and northeast, collecting tributaries such as Taohuaxi, Motan River, and Daxi River, while generally progressing in a southeast-southwest direction Additionally, the Liangtan River merges with the Jialing River outside the jurisdictional area.
Ecological environment
Nan’an District consists of urban artificial ecosystem and agricultural ecosystem The landscape is dominated by hills and plains The forest coverage rate is 28.2%.
The dominating vegetation in the project area is subtropical evergreen broad-leaved forest. Due to long-term human activities, the zonal vegetation in the project construction area is
The Mountain Ridge area has experienced significant degradation, primarily consisting of artificially planted trees, secondary shrubs, and natural weeds, with no rare plants or ancient trees present This region, situated within the main urban district, is heavily influenced by construction and human activities, leading to a stark decline in wildlife As a result, few amphibians, reptiles, and mammals inhabit the area, and no nationally protected species have been found within 200 meters of the project site during assessments.
Sensitive Areas There are three ecologically sensitive areas, Nanshan National Forest Park,
Liangfengya Municipal Forest Park and the Nanshan-Nanquan Municipal Scenic Area are located in the Nan’an District, with their geographic areas overlapping significantly For a visual representation of these sensitive areas, refer to Fig 4-3.
Figure 4-3 Relative position of sensitive points in Nan’an District
Nanshan National Forest Park, situated between Chongqing's urban district and Chayuan New Area, spans an area of 3,080 hectares and features two mountain ridges Geographically, it lies between 106°34′07″ to 106°39′54″ east longitude and 29°27′50″ to 29°35′36″ north latitude The park measures approximately 6 km in width from east to west and 15 km in length from north to south The current project focuses on upgrading and transforming the existing walking and hiking footpaths within the park, specifically through surfacing improvements, while community and public space regeneration are not part of this initiative.
Chongqing Liangfengya Forest Park, designated as a municipal forest park by the Chongqing Forestry Bureau in 1994, is located at the intersection of Liangfengya Village, Changshengqiao Town, and Lianhe Village, Huangjueya Town Its geographic coordinates are between 106°31′24′′ to 106°31′26′′ east longitude and 29°27′12′′ to 29°27′16′′ north latitude The park borders Nanshan Town to the north, Huangjueya Town to the west, and Changshengqiao Town to the east, while adjacent to state-owned forest land to the south, covering a total area of 1,009.3 hectares The project includes the upgrading and transformation of footpaths within the park, specifically surfacing existing paths, but does not encompass community and public space regeneration.
Nanshan-Nanquan Municipal Scenic Area, approved to be a provincial scenic area by
In 1989, Sichuan Province was designated as a municipal scenic area by the Chongqing Municipal People’s Government in 1999, primarily featuring Mount Nanshan and the South Hot Spring scenic spots Located within the Nanshan-Nanquan Municipal Scenic Area, the Nanshan area is conveniently situated near downtown, covering approximately 5.667 km² with coordinates of 29°12′N and 106°32′ to 106°38′E This region, part of the Tongluoxia Mountains, includes regeneration projects in the Nanshan Sub-district, encompassing the Huangjueya and Zhenwushan communities, as well as various footpaths and hiking trails aimed at renewing and upgrading the existing infrastructure.
Jiulongpo District consists of urban artificial ecosystem and agricultural ecosystem The landscape is dominated by hills and plains The forest coverage rate is 28.2%.
China's vegetation regionalization identifies the project area as part of the subtropical evergreen broad-leaved forest zone, specifically the Sichuan east basin and southwest mountain regions A site survey reveals that the zonal vegetation has significantly degraded due to prolonged human activities The existing flora primarily consists of manually planted trees, secondary shrubs, and natural weeds, with no presence of rare or precious plants or notable ancient trees.
The project site is situated in a densely populated urban area with numerous surrounding construction and human activities As a result, there is a limited presence of amphibians, reptiles, and other wildlife habitats During the survey, no nationally protected amphibian, reptile, or animal species were found within 200 meters of the project area, indicating a lack of wildlife distribution in this zone.
Sensitive Areas The World Bank Financed Project proposes to support Caiyun Lake Wetland
The Park Improvement Subproject focuses on the 110-hectare wetland park established along the Taohuaxi River between 2007 and 2010, managed by the Jiulongpo District Parks Bureau Surrounded by road networks and new residential developments, the park serves as an artificial wetland that provides a living water source for Taohuaxi, enhances ecological protection, purifies water quality, and showcases wetland plant landscapes, all within the city center The planned upgrades for Caiyun Lake Wetland Park will primarily enhance the sightseeing and functional exhibition areas without compromising the park's ecological functions or landscape integrity.
Socio-Economics
The area of Chongqing is 82,400 kilometres According to statistics, the household registered population of Chongqing is 33,921,100 in 2016, the GDP of Chongqing in 2016 is 1,755.925 billion yuan.
In 2016, Nan’an District had a registered household population of 700,100, with a GDP of 74.55 billion yuan and a per capita disposable income of 32,160 yuan for its residents.

Ambient Environmental Quality
The Yangtze River serves as the primary water source for the Nan'an District and Jiulongpo District projects Monitoring data indicates that all assessed factors at the Cuntan, Yuzui, and Fengshou Dam sections of the river meet the Category-III standards outlined in the Environmental Quality Standards for Surface Water (GB3838-2002), confirming that the overall water quality is good.
The ambient air quality in the Nan'an District Project and Jiulongpo District Project meets the standards set by the Ambient Air Quality Standards (GB3095-2012), with monitored levels of SO2, NO2, PM10, and PM2.5 indicating that the overall air quality is good.
The ambient noise levels monitored in both the Nan'an District Project and the Jiulongpo District Project meet the standards set by the Acoustical Environment Quality Standard (GB3096-2008) during both day and night, indicating a good status of acoustic environment quality.
A site survey conducted for the newly proposed park and public space revealed that out of nine locations—eight in Jiulongpo and one in Nan’an—six are small, underutilized land pockets, often used by local residents for vegetable planting due to challenging topography or location Notably, some sites, such as Huayan Riverside Park and Wutaishan, were previously residential or green areas Additionally, the Baitao Road greenbelt currently accommodates a construction material warehouse and a small machinery processing workshop, which poses a low risk of soil pollution.
5.1 "with project" and "without project"
Comparison and selection between “With Project” and “Without Project” have been made on the Nan'an District project and Jiulongpo District project.
The Nan’an District project aims to renovate old communities by upgrading road surfaces and underground pipelines, enhancing convenience and overall design Unified planning of green spaces, along with the installation of energy-saving streetlights and leisure seating, will significantly improve residents' living conditions and the community environment Upon completion, the transformation will fundamentally change the roads, greenery, and public facilities, giving the community a fresh appearance The introduction of a slow-traffic system will encourage more residents to visit the Waterfront Space on Nanbin Road, enhancing safety and increasing road capacity during peak hours Improved public spaces and parks will attract more visitors, while addressing issues like vehicle parking and sanitation Conversely, without the project, the old communities will continue to deteriorate, highlighting the pressing need for these improvements.
The construction of the Jiulongpo District project will significantly enhance the walking experience and promote walking as a preferred mode of travel, leading to reduced reliance on motor vehicles This initiative aims to improve traffic accessibility and integrate regional public spaces, strengthening community connectivity and public transport links Additionally, the project is expected to boost land value in surrounding areas, increase urban landscaping, and improve the ecological micro-system and microclimate By alleviating the urban heat island effect, it will contribute to the advancement of urban ecological civilization.
Improving the living environment in Jiulongpo District enhances residents' happiness and community vitality Conversely, failing to implement the project will hinder these improvements, leading to increased disadvantages that will become more pronounced over time Therefore, the negative impact of not executing the project on the external environment is evident.
The projects will enhance residents' livelihoods, with their benefits significantly surpassing any drawbacks They will greatly improve the living environment and quality of life in Nan’an and Jiulongpo Districts, positively shaping the urban landscape while promoting sustainable economic, social, and environmental development in the city.
Road design
According to the information of this project, the urban connecting road of Hugui Road has alternatives to compare.
The design of Hugui Road presents three alternative routes: the Turning Back Curve Route (Alternative 1), the Three-Layer Helical Interchange (Alternative 2), and the Taichang Road East Extension (Alternative 3) Among these options, the Turning Back Curve Route is recommended for its effectiveness.
In comparing the three alternatives, Alternative 1 stands out due to its shorter route, equal road design standards, and lower engineering costs, while Alternative 3 offers enhanced traffic functionality Environmentally, Alternative 1 occupies the least land, requires significantly less earthwork than Alternative 3, and has fewer nearby sensitive points, leading to a reduced noise impact Although all alternatives show similar effects on land use and the atmospheric environment, Alternative 1 is comparatively more favorable Consequently, the environmental impact assessment endorses Alternative 1 as the recommended plan for its superior engineering and environmental benefits.
Figure 5-1 Selected alternative for Hugui Road
6 ASSESSMENT OF IMPACTS AND MITIGATION MEASURES
The proposed project aims to enhance residential quality and foster social and economic development in the area, yielding substantial positive environmental and social benefits However, it is important to acknowledge that the project will also result in adverse environmental and social impacts during both the construction and operational phases.
Table 6-1 Potential Negative Impacts during Construction and Operation
Potential Environmental and Social Impacts during Construction
Potential Environmental and Social Impacts during Operation
Construction spoil and solid waste management
Impact on physical cultural resources
Noise impact of road operation
Air quality impact from road operation
Impact on surface water and groundwater from park operation
The environmental impact assessment indicates that the project's impacts are manageable, limited in scope, and can be effectively mitigated through proper construction and operational management The Environmental Management Plan (EMP) and Resettlement Action Plan (RAP) outline adequate measures to address these concerns Overall, the project is expected to have no significant adverse effects on the environment or society, will not lead to considerable degradation of natural habitats, and will not adversely impact physical cultural resources The mitigation strategies detailed in the EMP are designed to avoid, minimize, or compensate for potential environmental and social impacts.
Impacts during Construction Stage
Land Acquisition and Resettlement
The project will significantly impact the Liujiagang Community, Liuhulan Village, Tushan Town in Nan’an District, and the Guihuayuan Community, Lianhua Village, and Shanghao Community in Longmenhao Sub-district It involves the permanent acquisition of 14.2 mu of rural collective land, affecting 14 households comprising 36 individuals Additionally, the project will result in the demolition of 1,450 m² of rural houses, 539 m² of urban residences, 4,464.32 m² of non-residential structures on state-owned land, and 4,636.8 m² of houses with limited property rights, impacting a total of 31 households and 90 people.
A Resettlement Action Plan (RAP) has been developed for the Nan’an component to mitigate the effects of land acquisition and resettlement, in compliance with Chinese laws and World Bank OP 4.12 on Involuntary Resettlement, and has received World Bank approval Additionally, there is no expected land acquisition for the Jiulongpo district activities, and due diligence reports have been prepared for any land acquired prior to the project.
6.1.2 Impact on traffic and communities
The construction project in densely populated neighborhoods has led to social disturbances, including dust, noise, vibrations, nighttime illumination, and blocked access roads, raising significant safety concerns The mechanical operations and transportation of materials generate noise from machinery and vehicles, impacting residents' daily lives and travel efficiency However, these inconveniences are temporary and will cease once construction is completed.
In order to mitigate the impact of traffic and community disturbances, mitigation measures have been involved in the environmental management plans, including:
To optimize construction plans, all construction units must focus on busy roads and intersections, expedite progress, and keep residents informed about project developments through multiple communication channels.
Construction activities must be carefully regulated, ensuring that construction vehicles and equipment operate solely within designated areas It is essential that these operations do not disrupt the normal flow of traffic outside the construction zone Additionally, for construction intersections that are not easily identifiable, it is necessary to assign guards to manage and direct on-site traffic effectively.
To enhance safety measures, all construction sites must install prominent warning signs urging vehicles to reduce speed Additionally, "single lane" signs should be positioned at both ends of the construction area to ensure clear communication with drivers.
Emergency management should be strengthened, emergency rescue equipment and vehicles be completed, and fast and efficient handling be ensured in case emergencies and dangerous situations occur.
6.1.3 Road safety and disturbance near school
Tushan Branch Road in Nan’an District, adjacent to Tushan Campus of Longmenhao Primary School, currently ends at the school gate, serving students and staff Plans are in place to extend the road along the east side of the school, connecting it to an existing dead-end road, which will improve access for students and school personnel to nearby residential areas, replacing the current dirt trails However, potential negative impacts include road safety concerns and construction nuisances due to the road's proximity to the school Measures will be implemented to minimize these impacts.
To ensure the safety of students and school staff during construction, a designated access road should be clearly marked, fenced, and signed to keep them protected from construction vehicles Additionally, the contractor must appoint specific personnel to manage and direct traffic on-site.
To optimize construction scheduling, it is essential to plan activities during summer and winter breaks and avoid work near schools 15 days before and during college and senior high school entrance examinations.
(3) A closed hard fence shall be installed on the road section near the teaching building before construction, no lower than 1.8m;
(4) During school hours, the road construction must be paused until all students leave the road.
Noise predictions indicate that construction activities will produce daytime noise exceeding Category 2 standards within 150 meters and nighttime noise surpassing these standards at 200 meters from the main construction machinery, unless effective mitigation measures are implemented.
To mitigate noise impacts on nearby communities, a series of mitigation measures have been developed in the EMPs, including:
，1，High-noise construction sites shall be located in areas far away from the environmental sensitive points;
Effective construction organization requires a strategic layout of machinery and careful management of construction intensity To minimize disruption, it's essential to position construction equipment away from sensitive areas and to locate high-noise machines thoughtfully on-site Additionally, erecting fences around the construction area and setting up temporary enclosures for loud equipment, such as air compressors and diesel engines, can further mitigate noise impact.
，3，Choose low-noise equipment that meets national standards, strengthen the maintenance of such equipment, and avoid the high noise pollution caused by the abnormal working of such equipment;
，4，In accordance with the Emission Standard of Environment Noise for Boundary of
According to the Construction Site regulations (GB12523, 2011), construction activities must be scheduled thoughtfully, prohibiting the use of loud machinery near residential areas during nighttime hours (from 10:00 PM to 6:00 AM) In exceptional cases where continuous construction is required, prior approval from relevant authorities is mandatory, along with necessary communication with local residents.
Night construction activities that generate noise pollution, except for urgent repairs and emergency rescues, are prohibited in areas with a high concentration of noise-sensitive buildings for 15 days leading up to and during the college entrance and senior high school entrance examinations Additionally, any construction operations that could produce environmental noise pollution are banned within a 100-meter radius of examination rooms during these critical testing periods.
During the construction phase, it is essential to coordinate the movement of construction vehicles to minimize disruptions in busy traffic areas Effective communication and collaboration between the construction unit, construction party, and traffic administration are crucial to preventing traffic jams Additionally, during nighttime transportation, measures such as reducing speed and prohibiting honking will be implemented Regular maintenance of construction machinery will also be prioritized to ensure efficient operations.
During the construction project, certain existing roads will be utilized for transporting materials such as earth and stone It is crucial to schedule transportation times appropriately to minimize disruption Additionally, when vehicles traverse road sections near residential areas and schools, it is important to implement measures that enforce reduced speed and prohibit honking to ensure safety and maintain a peaceful environment.
Impacts during Operation Stage
Noise Impact
During the operational phase, noise primarily originates from public spaces and road traffic, with public noise levels ranging from 70 to 80 dB(A), typically aligning with the acoustic environment's functional requirements and causing minimal external disturbance However, without mitigation measures, traffic noise is expected to escalate over the years, leading to heightened daytime and nighttime noise impacts on sensitive areas as traffic flow increases.
To mitigate noise impacts on nearby communities, a series of mitigation measures have been developed in the EMPs, including:
，1，This Environmental Impact Assessment suggests that the project should plant protective green belts along both sides of the road;
When developing land adjacent to roads, buildings in the first row should cater to low noise standards, including commercial and public spaces, to serve as effective sound barriers The design of these structures should adopt a U-shaped layout oriented away from the road, minimizing noise exposure It is crucial to avoid placing bedrooms facing the road, while non-residential areas such as kitchens and bathrooms can be positioned towards the street to reduce noise disturbance.
To mitigate the impact of operational phase noise on residents and schools, it is essential to allocate special funds for noise monitoring and treatment Strengthening noise monitoring during this phase is crucial In cases where noise levels disturb the community, affected residences and schools should be fitted with sound insulation windows that can reduce noise by 15 to 20 dB(A), significantly decreasing the adverse effects of traffic noise.
During the operational phase of the project, the primary source of air pollution is vehicle exhaust emissions from road traffic, characterized as a dispersed and flowing line source with low emission height Pollutants tend to diffuse within a limited area, with daytime pollution levels being higher due to varying traffic flows To mitigate this impact, it is recommended that relevant authorities enhance management practices and enforce vehicle exhaust emission standards, while also planting green belts alongside the road to improve air quality Overall, the volume of vehicle exhaust generated is minimal and is unlikely to significantly alter the atmospheric environment function zone, resulting in a minor impact.
During the operational phase, the primary source of new wastewater is the sanitary sewage generated by urban residents in public spaces This sewage is collected and transported via gravity flow into the municipal sewage pipe network, eventually reaching the sewage treatment plant After treatment and compliance with discharge standards, the wastewater is released without negatively impacting the water environment.
The project operation is expected to generate domestic waste in parks and public spaces, with an estimated daily production of 0.24 tons in Nan’an district and 0.36 tons in Jiulongpo Municipal sanitation units will ensure timely collection and disposal of these wastes, preventing any waste management issues.
Impacts on Sensitive Areas
The project will involve such three sensitive areas, including:
• Liangfengya Municipal Forest Park; and
• Nanshan-Nanquan Municipal Scenic Area
See Figure 6-1 for the positional relation between the project and the sensitive areas See Figure 6-
2 for the site survey of the sensitive areas.
The project supported neighborhood revitalization, hiking footpaths, and slow-walking footpaths fall into the sensitive areas Specifically,
Nanshan Hill features a flat topography that encompasses Nanshan Street Committee, where a revitalization project aims to enhance two aging communities comprising 1,740 households Although these communities are situated within the Nanshan-Nanquan Scenic Area, the construction will occur in an already developed region, ensuring that the ecology and landscape of the scenic area remain unaffected.
Hiking footpaths, typically 1-2 meters wide, serve as essential trails linking communities on and around Nanshan Hill while also offering recreational opportunities This project aims to enhance these trails by connecting specific segments, adding pavement, installing resting facilities, and providing necessary illumination The design process has carefully considered the surrounding landscape and ecological conditions, ensuring that the improvements are minimal and will not significantly affect sensitive areas.
Slowing walking footpaths are typically wider and offer improved walking conditions compared to trails Additionally, the existing slowing walking paths located in sensitive areas are not expected to significantly impact these environments.
Figure 6-1 Positional relation diagram of the project and the sensitive points
Figure 6-2 Site survey of the sensitive points
The "Improvement to Caiyun Lake Wetland Park" subproject aims to enhance the public recreational facilities within Caiyun Lake National Wetland Park Proposed activities include the construction of landscape features such as corridors and pavilions, protective works, activity sites, and squares, along with the installation of water and electricity networks Additional enhancements will involve landscape art, functional buildings like restrooms and management rooms, public furniture, road paving, and signage This project seeks to expand existing facilities, further enriching the park's offerings for visitors.
The park reconstruction will preserve the park's natural integrity and functional services, with only short-term environmental impacts during construction The project emphasizes "Taoyuan (Peach Flower Origin) culture" through the planting of peach trees and diverse flora, enhancing the wetland park's ornamental value and biodiversity By incorporating native species, the initiative aims to mitigate the risks posed by invasive alien species, resulting in a positive influence on both the natural and cultural environments of the park.
7 ENVIRONMENTAL AND SOCIAL IMPACT MANAGEMENT
The framework applies to the project Component 1 District Regeneration Planning and
The Nan'an District is set to implement a Community-Led Bottom-Up (CLBU) approach for the regeneration of three pilot neighborhoods: Nanping, Huayuanlu, and Nanshan This innovative strategy aims to enhance the revitalization process, with funding for the regeneration efforts allocated under Component 2 of the project.
The screening of technical assistance activities during project preparation revealed that these initiatives operate at a macro level and are not directly tied to immediate investments The project embraces a "new urbanization approach," focusing on a "people-centered" model rather than traditional "green field" development, which typically involves expansion and demolition This approach emphasizes enhancing existing facilities and services while fostering community participation in planning and implementation Consequently, it is essential to integrate environmental and social considerations into the scope of work and Terms of Reference (TORs) for these technical assistance activities.
The Subcomponent 1e initiative in Nan'an District implements a Community-Led Bottom-Up (CLBU) Approach for the regeneration of three neighborhoods—Nanping, Huayuanlu, and Nanshan—integrating physical regeneration efforts with comprehensive management procedures outlined in the Environmental and Social Management Framework (ESMF) This framework addresses potential environmental and social impacts through systematic screening, safeguard documentation, consultation, disclosure, and ongoing monitoring and reporting Additionally, the ESMF incorporates a capacity-building plan to enhance community engagement and ensure sustainable development practices.
8 PUBLIC CONSULTATION AND INFORMATION DISCLOSURE
Public consultation and information disclosure have adhered to national laws and World Bank safeguards policies During the preparation phase, two rounds of consultations were conducted, utilizing public meetings, field interviews, and questionnaire surveys within the communities affected by the project.
Before the consultations, essential project details, potential environmental impacts, and proposed mitigation measures were made available on the website (http://www.cqmsy.com/) Additionally, informational posters were displayed in key communities within the project areas After this disclosure, public consultations took place, engaging affected communities through field interviews, public meetings, and questionnaire surveys.
The project has garnered significant public support, with many expressing a desire for expedited infrastructure and environmental improvements The primary concern among the public is noise pollution, followed by issues related to the ecological environment, waste residues, exhaust gas, and wastewater, all of which the proposed project aims to address The project owners are committed to implementing the prevention and control measures outlined in the Environmental Impact Assessment to minimize environmental pollution during construction Public concerns have been carefully integrated into the project design and environmental protection strategies.
Public concerns have been thoroughly addressed in the project design and Environmental Impact Assessment (EIA), leading to the development of effective mitigation measures within the Environmental Management Plans (EMPs) to prevent, reduce, or compensate for any adverse impacts.

Environment monitoring report
During project implementation, project owners and PMOs must submit environmental monitoring reports to the Nan’an and Jiulongpo Environmental Protection Bureau (EPB) and the World Bank, with support from the Independent Environmental Consultant This reporting aims to ensure the effective execution of Environmental Management Plan (EMP) mitigation measures, detect potential issues early for timely corrective actions, and gather insights to inform future projects.
The main contents of the report include:
2) Environmental management organization setup and responsibilities;
3) Key construction activities, associated environmental impacts and actual implementation of EMP mitigation measures, including any problems and remedial actions or plans;
4) Implementation of environmental monitoring plan and key results;
5) Any public complaints (records, resolution and public feedback);
During construction, contractors and supervision engineers are required to provide periodic environmental reports to the project owners.
Environmental Training Plan
Environmental capacity training is crucial for effective project environmental management, targeting PMO staff, project owners, contractors, and supervision engineers Before construction begins, the Chongqing PMO will conduct comprehensive environmental training for contractors, workers, supervision engineers, and project management personnel to ensure compliance and enhance environmental stewardship.
EMP Budget
A budget has been allocated for the implementation of the Environmental Management Plan throughout both the construction and operational phases This total budget encompasses environmental mitigation measures, monitoring, and management, along with primary works aimed at reducing and eliminating adverse environmental impacts It is important to note that many of these mitigation measures are management practices integrated into the overall contract, and may not be explicitly itemized in the budget.
The environmental protection investment for the Nan’an District Project is estimated at RMB 8.5 million, representing 0.44% of the total project investment of RMB 1,942,460,000.
The Jiulongpo District Project has allocated an estimated RMB 3.7 million for environmental protection, which represents 1.46% of the total investment of RMB 25,270,000.
