Chapter 1General
1.1Project Background
World Bank-financed Jiangxi Poyang Lake Basin and Ecological Economic Zone Small Town Development Demonstration Project is a demonstration project of Jiangxi Province, which aims to promote the harmonious development of ecological protection and urban construction, to improve urban and rural infrastructure, and to accelerate the urban and rural integration of the province by introducing international experiences with loan project as carrier, and according to Chinese urbanization development strategy as well as the urbanization demand of Jiangxi Poyang Lake Basin and Ecological Economic Zone.This Annex is the Environmental Codes of Practice for the source water transmission pipeline engineering and water (transmission) distribution engineering under the safety drinking water project in LuxiCounty urban area and surrounding towns and villages. Project content: Construction of total around 5.5km DN800 water transmission pipeline; construction of main and branch pipes for water distribution within the newly increased water supply scope, as well as the main pipes for water distribution and branch pipes for water distribution, excluding the pipes accessing households. The newly increased water supply pipeline is 32.5km in total.
This Annex includes the specific environmental impact analysis and corresponding Environmental Codes of Practice for the water transmission and supply pipeline subproject; and together with the Environmental Codes of Practice for Small Civil Works (Annex 1.1), it forms the complete Environmental Codes of Practice for the water transmission and supply pipeline subproject. The geographic location is shown in Figure 1. In preparing this ECOP, we made reference to Detailed Rules of Jiangxi Province on Safe Construction, EHS Guidelines, operational policies and safeguard polices of the World Bank and other materials.
Chapter 2 Construction Site Management
As the main content of the Environmental Codes of Practice, this chapter brings forward the special environmental protection measures to be adopted by contractor in municipal pipeline subproject and the basic requirements on environmental management. This chapter briefly introduces the requirements on management of construction site, mainly including the construction nameplate, construction enclosure, curb fender, and interim road. Construction unit must observe the management regulations of local environmental protection department, and accept the frequent inspection of environmental supervisor.
2.1 Setting of Construction Nameplate
(1)On construction nameplate, the construction unit shall provide the information on construction and engineering schedule, service interruption, traffic detours and interim public traffic lines, and relocation, etc.;
(2) Limit construction activities at night;
(3) If necessary, control the impacts of construction at night on surrounding areas, and notify the surrounding communities in advance so that the people there can take necessary actions;
(4) Inform the public of service interruption (including of water, electricity, fuel gas, and public traffic lines) at least five days ahead by putting up a notification at project site, public traffic stops, as well as affected residents and enterprises.
2.2 Setting of Construction Enclosure
(1)The enclosure set up shall be straight, orderly, clean, beautiful, and damage-free, and the appearance shall be harmonious with surrounding environment;
(2)The enclosure constructed on road shall be within 5m range of visibility at crossroad. Straight and rigid enclosure of metal mesh panel shall be set up without blocking the visual line of drivers and pedestrian, and in the precondition of guaranteeing traffic safety. Within 5m range of visibility, it’s forbidden to stack any article.
(3)In case the enclosure is equal to or less than 5m from residence, or the construction point is equal to or less than 15m from sensitive buildings like residence, hospital and school, etc., proper measures shall be taken to lower the noise, such as raising the enclosure, etc., and the enclosure in sensitive areas shall be up to 3m high; and the scope of 5m outside the enclosure shall be kept clean.
(4) Never stack materials, tools, and earthwork, etc. within the scope of 1m inside the enclosure.
(5)For engineering with construction period of more than 30 days, the boundary of construction site shall be enclosed and have color plate enclosure; the enclosure shallbe at equal to or more than 2.5m/ 3m at construction site of common areas/ key areas respectively;
(6)Metal shape shall be adopted for supporting and consolidating the lower end of covering steel plate in case the excavation width of ditch (pit) is equal to or more than 0.8m;
(7) Never use the enclosure as retaining wall or the support of other facilities and equipment;
(8)For pipeline engineering in key areas, the boundary of construction site shall be closed down, and shall have enclosure.
2.3 Setting of Construction Curb Fender
(1)There shall be curb fender at the construction boundary for road-occupied pipeline engineering with construction period equal to or more than 30 days;
(2)Never use red and white flag, safety isolation rope, or other materials to replace the construction curb fender.
(3) Enclosure shall be closed down continuously when construction curb fender is used; and all construction curb fenders shall be fastened solidly and uniformly, and maintained clean and damage-free;
(4)In case hidden well cover is opened or raised for construction on urban road maintained open to traffic, folding construction curb fender shall be adopted at the boundary of construction area;
(5)The setting of construction curb fender shall surely make the long-side section of channel steel on the foundation face towards construction area; in case construction passageway is set up between construction curb fender and construction area, the passageway shall be equal to or more than 0.6m wide;
(6)Construction unit’s name shall be printed horizontally on construction curb fender. Never use construction curb fender non-accordant with the unit’s name at construction site;
(7) In case the external surface of buildings (structures) is painted, refurbished, or cleaned, construction curb fender shall be used as fully-closed enclosure at the boundary of construction area, and various mechanical equipment, tools, and materials shall be placed within the scope of enclosure;
(8)Never remove construction curb fender before the road construction takes interim passing measures or the engineering is completed;
(9)In key areas, road pipeline shall be constructed by means of “excavating a section, paving a section, and renovating a section”, and the whole pipeline shall never be excavated simultaneously.
2.3 Setting of Interim Road
(1)For construction occupying urban road, the construction unit shall observe relevant regulations of public security, traffic department, and road administration department, handle relevant examination and approval formalities, and set up interim road according to specifications;
(2)Construction unit shall observe the license regulations on construction period strictly, and shall never execute construction by occupying road or exceeding the licensed construction period;
(3) Set up interim road according to regulations for construction occupying urban road and impacting the travelof vehicles and pedestrian;
(4)For construction occupying footway, the construction unit shall build up solid, flat and continuous pedestrian shortcut with safety edge enclosure at the access sideneighboring to school, commerce, enterprises, office building or residence, etc., and dispatch special personnel to guide the traffic at peak period of traveling, in order to guarantee the safe passing of the pedestrian;
(5) The construction unit shall adopt sheet flattening method for construction in case the ditch or pipeline slot is excavated on urban road which is used as traffic road, and the work can not be completed on the very day;
(6)The supporting and consolidation scheme shall pass safety argumentation, and be reported to construction unit for approval; the steel plate covering road shall be at least equal to or more than 0.03m thick. The edge of the steel plate and metal slope rack adopted shall be burnished to remove sharp edges and burrs, in order to ensure the safety of personnel and vehicles;
(7)Metal shape shall be adopted for supporting and consolidating the lower end of covering steel plate in case the excavation width of ditch (pit) is equal to or more than 0.8m.
