Integrated wastewater discharge standard
1 Application scope
This standard specifies the terms and definitions of water pollutant discharge, standard grading, pollutant discharge control requirements, pollutant
monitoring requirements, implementation and supervision.
This standard is applicable to the discharge management of water pollutants in the existing pollutant discharge units [Translator note. ?€?unit?€? refers to an organization/entity] of Tianjin, as well as the environmental impact assessment of construction projects, the design of environmental protection facilities of construction projects, the completion acceptance, the discharge management after commissioning.
This standard applies to the discharge of water pollutants permitted by law. The location of newly-established pollution sources and the management of existing sources in special protection areas shall be in accordance with the Laws of the People's Republic of China on the Prevention and Control of Water Pollution, the Law of the People's Republic of China on Marine Environmental Protection, the Law of the People's Republic of China on Environmental Impact
Assessment, as well as other laws, regulations and provisions.
In accordance with the principle that the integrated discharge standards and industrial discharge standards are not cross-executed, where there are national or local industry water pollutant discharge standards, it shall implement the corresponding industrial water pollutant discharge standards in accordance with their scope of application. For other pollutant-discharge units, the water pollutant-discharge units shall implement this standard.
The water pollutant-discharge control requirements as specified in this standard are applicable to the discharge of water pollutants directly or indirectly by the pollutant-discharge unit outside its legal boundary.

3.6
Indirect discharge
The behavior that pollutant discharge units discharge water pollutants into the public sewage treatment system.
3.7
Public sewage treatment plant
The enterprise or institute which collects wastewater through sewage
pipelines (canals) and so on, provides waste water treatment services to more than two pollutant discharge units, and whose discharge can meet the requirements of relevant discharge standards, including urban sewage
treatment plants of various scales and types, regional (including various industrial parks, development zones, industrial agglomeration zones)
wastewater treatment plants and so on. Its wastewater treatment grade shall reach grade II or above.
3.7 [should be 3.8]
Industrial park
Various industrial parks, development zones, bonded zones, export
processing zones, eco-industrial demonstration zones, industrial
agglomeration zones, etc. which are approved by the State or Tianjin
Municipality with clear geographical boundaries.
4 Standard grading
4.1 This standard is divided into three grades in accordance with different discharge destinations and different functions of wastewater, of which the grade I and grade II are direct discharge standards, the grade III is indirect discharge standard.
4.2 For the wastewater which is discharged into the water-body of category IV (inclusive) and above in GB 3838 and the water-body within its impoundment area, as well as the wastewater which is discharged into the category II and category III sea areas in GB 3097, it shall implement the grade I standard. 4.3 For the wastewater which is discharged into the water-body of the category must not negotiate for discharging.
5.4 Other provisions
5.4.1 The base water-displacement of the unit-product from each industry shall implement the corresponding national and local standards.
5.4.2 In addition to the discharge limits as specified in this standard, the discharge of water pollutants shall also meet the control limits of total pollutant discharge which are approved or specified by the national or local
environmental protection administrative department.
6 Pollutant monitoring requirements
6.1 For the sampling of wastewater as discharged from the pollutant discharge unit, it shall, in accordance with the types of the monitored pollutants, be performed at the specified monitoring location of pollutant discharge. The pollutant discharge unit shall follow the relevant requirements of the national technical specifications on pollution source monitoring to arrange the sampling port, it shall provide a permanent marking of pollutant discharge outlet at the monitoring position of pollutant discharge.
6.2 For the requirements of the installation of automatic pollutant discharge monitoring equipment, for new (rebuilding, extending) construction units and existing units, it shall be implemented in accordance with the relevant laws and the provisions of ?€?Administrative measures for automatic monitoring of pollution sources?€?.
6.3 The pollutant discharge unit shall monitor the discharge status and keep the original monitoring records in accordance with the requirements of relevant laws and regulations.
6.4 The frequency, sampling time, quality control and other requirements for monitoring the pollutant discharge shall be implemented in accordance with the provisions of the national and local relevant technical specifications on pollution source monitoring as well as the requirements of the environmental protection administrative department.
6.5 The concentration of water pollutants is determined by using the method standards listed in Table 3.
6.6 After this standard is issued-implemented, if there are new standards for methods monitoring the pollutants as listed in Table 3, then, such standards are also applicable to the determination of corresponding pollutants of this discharge standard.
