24x7 Real Time Monitoring of Pollution from Industries
“24x7 Real Time Monitoring of Pollution from various industries is a
major revolution brought in by the NDA Government. Earlier method of
physical sampling and lab testing was found to be inadequate as it could
not capture pollution levels all 24 hours. With on-line monitoring the
situation has completely changed and monitoring can be done
continuously. The industries now are taking steps to install new
equipment to meet environmental norms. We shall also bring about
necessary changes in law to enable use of on-line data as legal
evidence” – Prakash Javadekar.
In 2015, notices were issued to 3145 highly polluting industries under
17 categories for installation of 24x7 continuous effluent/emission
monitoring systems, out of which 1475 have already been installed these
devices and 805 industries shall complete the process by the end of
March, 2016. Thus by March end, 2280 industries will be equipped with
24X7 monitoring systems.
321 industries are currently closed and orders are being issued to
ensure that they reopen only after installation of these devices.
Closure orders have been issued to 141 industries and action is being
initiated against the rest 403 industries.
24x7 continuous monitoring systems cover emission parameters like PM
(Particulate Matter), SO2 (Sulphur Di-oxide), NO2 (Nitrogen Di-oxide),
CO (Carbon mono-oxide), Ammonia, etc. and effluent parameters like
flow, pH, BOD (Bio-chemical oxygen demand), COD (chemical oxygen
demand), TSS (Total suspended solid), Ammonical Nitrogen etc. Data
connectivity has been established with 1101 units of 17 categories with
CPCB and SMS alerts and emails are automatically generated whenever
standards are exceeded for more than 15 minutes. On average, around 1000
SMSs for exceedances are being generated on daily basis beside emails
and these SMSs are being sent to Stake holders (CPCB, SPCB and
Industry). Industries are taking action based on the information
received to control emission and effluent and report this action taken
on an email id cems.cpcb@nic.in.
Some of the industries like oil refineries and petrochemical have
requested time up to June 30, 2016 since in installation of online
monitoring systems for parameters like PM and CO requires shutdown which
is carried out as per schedule decided by Ministry of Petroleum. Power
plants have also requested time up to June 30, 2016 for installation of
online monitoring system.
Substantial progress has been made so far in the direction of online
monitoring of industrial pollution. However, industries which have not
installed CEMS as yet need to do so immediately and avoid the necessity
of closure directions. Moreover, those industries which have not yet
established connectivity need to ensure it without any further delay.
CPCB is maintaining constant watch on the progress to ensure that no
industry required to install these devices is left out.
