T/CECRPA 017-2025 Implementation Standards for Ecological Environment Monitoring during the Construction Period of Urban Rail Transit Projects
T/CECRPA 017-2025 Urban rail transit construction period ecological environment monitoring implementation standards
Basic Information
Scope
Scope: This standard specifies the environmental monitoring sites, monitoring items and frequencies, monitoring methods, monitoring results and evaluation, and the content of monitoring reports during the construction period of urban rail transit projects. This standard applies to ecological environmental monitoring work during the construction period of new, modified, and expanded urban rail transit projects. This standard does not apply to online monitoring and emergency monitoring. Main technical content: 3. Terms and definitions The following terms and definitions apply to this document. 3.1 Urban rail transit Refers to an urban public passenger transportation system mainly guided by wheel-rail systems. Depending on the volume of traffic and mode of operation, urban rail transit includes subway, light rail, trolleybus, and monorail trains. 3.2 Monitoring Refers to the long-term, continuous collection and acquisition of information reflecting the environmental conditions, change characteristics, and development trends of the construction route and surrounding environmental objects of the project through instruments, on-site inspections, or remote video monitoring, as well as the analysis and feedback of this information. 3.3 Depot A basic production unit for parking vehicles, managing vehicle operation and maintenance, conducting inspections, and undertaking major overhauls or repair work. 3.4 Parking lot A basic production unit for parking assigned vehicles and managing vehicle operation and maintenance. 3.5 Water-sensitive sites Surface water bodies such as rivers, lakes, and reservoirs that may be affected by construction wastewater from urban rail transit projects. 3.6 Environmental air and sound-sensitive sites Hospitals, schools, government agencies, scientific research units, residences, and sanatoriums within a certain distance of urban rail transit projects. 3.7 Ecological environmental sensitive areas Areas that may
