Environment Ministry notifies revised standards for Common Effluent Treatment Plants (Cetps) Across industrial clusters
The
Ministry of Environment, Forest & Climate Change has notified the
revised standards for Common Effluent Treatment Plants (CETPs) operating
at various industrial clusters in the country. The primary aim of the
revised standards is to minimise water pollution. These standards were
finalised after extensive consultations with industries and other
stakeholders and detailed deliberations with the Central Pollution
Control Board (CPCB). The revised standards were notified on January 1,
2016.
The revised standards will help in significantly improving the
performance of CETPs through implementation of design inlet quality,
addressing the problems of the coastal pollution due to industrial
discharges and keeping a close watch on the impact of discharge of
industrial effluent on soil and ground water quality.
A provision of soil and groundwater quality monitoring twice a year
(pre- and post-monsoon) has been introduced in the standards to study
the impact of disposal of treated effluent on land, in case of mode of
disposal as ‘on land for irrigation’. This monitoring will be carried
out by the respective CETP management.
The mode of ‘Discharge into sea’ (marine outfalls) providing very high
dilution will qualify for a relaxed maximum permissible concentration of
Chemical Oxygen Demand (COD). The maximum permissible concentration of
Fixed Dissolved Solids (FDS) by constituent units to CETP has been
specified in terms of maximum allowable contribution value.
The State Pollution Control Boards are empowered to prescribe standards
for Inlet quality of effluent in respect of Bio-chemical Oxygen Demand
(BOD), Chemical Oxygen Demand (COD), Total Suspended Solids (TSS) and
Total Dissolved Solids (TDS) considering CETP design and local needs
& conditions. This provision will help in enforcing the norms for
treated effluent quality for the CETP constituent industrial units.
The draft standards had been uploaded on the website, seeking
views/comments of stakeholders including general public. The standards
were also studied by an Expert Committee, consisting of representatives
of the Ministries concerned, environment experts and social scientists.
