Concentration ( level )Load ( the amount contained )Restriction background :• Technology & economic feasibility• Environmental capacity ( e.g water )9SETTING ENVIRONMENTAL QUALITY STANDARD(A) Ideal approach :-Load carrying capacity pollution
Quota principal propositionally for every
pollution source(B) Practical approach
Best Practicable Technology,gy, there are middle
technology and economically appropriate

SETTING ENVIRONMENTAL QUALITY STANDARD

Principles(1) Practical approach• Effective, could decrease pollution load
• Administrative, administratively easy to implement• Economy, will not cause high cost economy

SETTING ENVIRONMENTAL QUALITY STANDARD

Principles(2)Technology based, measurable environmental standard
implementation can be changed gradually(3) The use of key parameter, specific and important parameter,
economically easy to control and monitor(4) The used of load concept, not affected by dilution
