The overall structure of the Total Pollutant Load Control System (“TPLCS”)

Chapter 1 Need for the TPLCS

1.1 Overview of the TPLCS
Water pollution occurs when the balance of nature is lost due to the increase of pollutant discharge load resulting

from human activities. A countermeasure for addressing this loss is to reduce pollution load effluent. The Total

Pollutant Load Control System ("TPLCS") is an effective scheme for that purpose.

1.2 Structure of the TPLCS

(1) Types of water pollution

Water pollution can be categorized into four main types: health damage caused by harmful substances, problems

related to public sanitation concerning bacteria, organic contamination, and eutrophication. The TPLCS principally

addresses organic contamination and eutrophication.

(2) Measures for preserving aquatic environment

Measures for preserving an aquatic environment are categorized into source measures, which aim to reduce the

amount of pollutant load effluent from sources, and direct purification measures, which aim to purify the

environment directly within water areas. The TPLCS focuses on source measures.

(3) Policy measures implemented by the administration and the structure of the TPLCS

Implementing source measures through the voluntary initiatives of emitters is impossible. Some political

involvement is needed. The TPLCS seeks to regulate the effluent load released from emitters as well as

comprehensively taking various measures, such as the construction of sewage systems, and providing administrative


1.3 Experiences and lessons of Japan

Along with high economic growth, Japan has seen an increase in pollutant loads, occurring in terrestrial ecosystems

and flowing into aquatic systems. Japan has also experienced serious water pollution, which it has overcome through

measures such as the TPLCS. It is important to promptly undertake measures where they are most practicable.

1.4 Necessity to introduce the TPLCS

As enclosed water areas have limited water exchange and easily accumulate pollutant load, the need is to reduce

and control the total amount of pollutant load. The TPLCS can be utilized as effective pollution reduction measures

for those water areas with severe water pollution as well as a method for controlling pollutant load in areas that are

expected to be developed in the future. There has been an increasing need for this system as a measure for conserving

water quality in countries where economic growth has been accelerating.

1.5 Basic principles of the TPLCS

(1) Basic principles of the TPLCS

To quantitatively measure all pollutant discharge load that flows into water areas, analyze its relationships with the

water quality of water areas, set quantitative reduction goals, formulate control plans and, step by step, pursue the


(2) Points to allow the TPLCS to function effectively

It is important to quantitatively control and reduce the pollutant discharge load, formulate total pollutant load

control plans for all pollutant load sources from a comprehensive perspective, and pursue reduction and control

pollutant load should be implemented within the environmental capacity of the water area in

the first instance.

v) For factories and business establishments, total pollutant control should be conducted on the

pollutant discharge load. For newly built factories and business establishments, environmental

measures for existing factories and business establishments should be pursued, as far as

possible, to allow for the regional development, and a specific amount of new development

activities should be authorized on condition that they introduce state-of-the-art environmental

technology, considering the margin compared with the target load5.

vi) Both the objective for managing the discharge load, considering the status of water quality and

the variation of discharge load, and the total pollutant load control plan should be reviewed.

5 This depends on the type of institution employed for constructing new factories and business
establishments. Japan adopts a notification procedure, and when the contents of the notification do not
meet the effluent standard or total pollutant control standard, the concerned prefectures provide
instructions or program change orders. In the Seto Inland Sea, permits are given for the construction of
factories and business establishments under the Law concerning Special Measures for Conservation of
the Environment of the Seto Inland Sea.

Chapter 3 Development of institutions and frameworks for effective
operation of the TPLCS

Water quality examination and assessment on the current status of the industrial structure or the

regional characteristics need to be conducted to implement the TPLCS. It is important to design the

TPLCS and to arrange for various related frameworks by making full use of available information.

Since, in principle, the total pollutant load control addresses all sources and related administrative

sectors cover a broad range, it is also important to establish coordinating and cooperative

relationships with these sectors.

Table 3.1 summarizes the main related frameworks and institutions that need to be established for

the implementation of the TPLCS.
