19-03-2018 Continuous Effluent/Emission Monitoring Systems (CEMS) of Industries B. R. Naidu Director Central Pollution Control Board Vadodara February 24, 2018 CEMS (Continuous Emission/Effluent Monitoring System) The system composed of Equipment, Instrument to draw, condition, analyze the flue gas sample/wastewater and provide permanent record of emissions/discharge or process control parameters continuously at real time basis is called Continuous Emission/Effluent Monitoring System (CEMS) 1
19-03-2018 Benefits of CEMS � Provides real time data. � Remotely accessible to operator/regulator. � Greater transparency in monitoring of performance. � Continuous performance check of Air Pollution Control Devices / treatment methods of wastewater and optimization of resources used. � Time series analysis possible with continuous data. Reduction in regulatory visits as well as long term monitoring cost. � � Expected better compliance through self regulation by industry hence lower emission.

19-03-2018 DIRECTIONS ISSUED ON 05-02-2014 DIRECTIONS ISSUED BY CPCB to all SPCBs/ PCCs under Section 18 (1)(b) of Water Act and Air Act Date of issue: February 05, 2014 Target Date: March 31, 2015 Target date extended to: June 30, 2015 CPCB ISSUED DIRECTIONS to defaulting Industries (17 Category) under Section 5 of E P Act: after June 2015 DIRECTIONS ISSUED ON 05-02-2014 a. To Install online continuous Stack Emission Monitoring Systems (CSEMS) in 17 categories of highly polluting industries and in Common Hazardous waste and Biomedical waste incinerators for the parameters(industry/sector specific parameter ) specified by CPCB; not later than by March 31,2015 ; b. To install online effluent quality monitoring system at the outlet of effluent treatment plants of the 17 category industries and in CETPs for the measurement of the parameters(industry/sector specific parameter ) like flow, pH, COD, BOD, TSS and other specified parameters specified by CPCB; not later than by March 31, 2015; Contd.. 3
19-03-2018 Contd.. DIRECTIONS ISSUED ON 05-02-2014 c. To connect and upload the online emission and effluent monitoring data at SPCBs/PCCs and CPCB server in a time bound manner but not later than by March 31,2015; d. To ensure regular maintenance and operation of the online system with tamper proof mechanism having facilities for online calibration ; e. To submit bank guarantee of 25 % of the cost of online monitoring systems (emission and effluent whichever applicable) for ensuring timely installation of online monitoring systems within 90 days from the date of receipt of directions issued by SPCBs/PCCs to the industries; Later on the same directions were issued for installation of CEMS and data submission for Grossly Polluting Industries (GPI) on River Ganga basin viz., Textile, Dairy, Slaughter House etc. List of Parameter for Continuous Monitoring as per CPCB Guidelines � All 17 Category of industries has to monitor effluent parameters except Cement industries � pH, BOD, COD, TSS are common parameters to be monitored by most category of industries � Flow meter has to be installed by all category of industries for monitoring effluent discharged. � CCTV camera has to be installed by all ZLD units and units discharging Effluent to CETP and the video feed of the those cameras hat to be submitted to CPCB 4
19-03-2018 Real-time data from Industries- Initiation & Challenges Faced Heterogeneous Systems: � Multiple instruments � Multiple instrument suppliers � Multiple Data formats � Multiple platforms � Multiple Communication protocols � Correctness of Data transmitted ????? � Data collection from heterogeneous systems Approach adopted by CPCB for data collection from CEMS In order to overcome the heterogeneity of the systems different Instrument Suppliers (IS) were allowed to install their physical servers (Govt. data on Cloud was not allowed) in CPCB and asked to fetch the data from all their installations and display real-time data in their respective web-portal (Now with change in policy, servers of private suppliers are removed and is switched to cloud based system) ����������� ������������� �� ����������� ����������� �� �� ������������� ����������� ����������� ����������� �� �� �� ����������� ������������� ����������� ����������� �� �� �� ������� ������� ������� ������� ������� ������� ������� ������� �������� �������� �������� �������� � � � � � � � � ������� ������ ������ ������ ������� � � ������ ������ ������ ������ ������� ������ ������ � � ������� ������ ������ ������ ������ ������ ������ ������� ������� � � ������ ������ ������ 5
19-03-2018 Scenario: Post Directions issued The number of industries installed and started transmitting data gradually increased post directions issues. The following table shows the total number of industries integrated data with CPCB Server since 2010: ���� ���� ���� ���� ��� ��� �� ��� ��� �� �� ���������������� �����!� �� ���������������� �����!� ���������������� �����!� ���������������� �����!� �������������� �������������� �������������� �������������� �������� ��"#� �������� ��"#� �������� ��"#� �������� ��"#� ��������� ��������� ��������� ��������� �$�$��� �$ � �$����� �% & �$����� �$$ ' �$����&�()���*���� ������+ �,$ - �$�&��, �$$ �� �$�,��' �-$$� �'� �$�'��% ��&$ &�� All IS (Technology Provider) servers are shifted to cloud servers and there are no physical servers installed at CPCB now 6
19-03-2018 CPCB Central Portal for CEMS data � Data was available in many IS servers and in different formats. � Access of data from different servers/portals was herculean task � CPCB has developed the common software which gets data from all instrument suppliers’ server and can be access at its Central Portal. � Officials of CPCB and SPCB has access to this central portal � Data on single platform may be used for compliance verification 7
19-03-2018 CPCB Policy for Real Time CEMS data collection CPCB has defined data submission policy for Industry, Instrument Supplier (Technology Provider) and SPCB Data Policy for Industry: � Industry has to make arrangement of data submission through IS which are submitting data to CPCB as per CPCB laid down requirements � Sole responsibility of real time data submission to CPCB lies with the industry. Industry has to ensure that data is received at CPCB portal on real time basis without any interruption and if interruption are observed, IS should be immediately informed and corrective action have to be taken by industry and IS. � Each industry has to ensure 85% of data availability � Industry can migrate to one IS to other while it has to ensure: All previous is migrated to new IS server • Migration information is shared with CPCB along with data details • New IS follows the CPCB requirements/procedures • CPCB Policy for Real Time CEMS data collection contd… Data Policy for Instrument Supplier (Technology Provider): � CPCB does not register any agency as IS/Technology Provider. Any firm either instrument supplier or combination of instrument supplier and software developer can become a Technology provider an submit data to CPCB on behalf of any industry, but as per CPCB requirements/formats � Ownership of real time online continuous emission/effluent monitoring station data collected at the server of IS/technology provider lies with CPCB & SPCB � Once an industry started data submission through any one of the IS/technology provider, it is the responsibility of IS/technology provider to collect, display and forward the data to CPCB Central Portal and SPCB’s or any other portal without delay � IS/technology provider will not charge any additional cost to the industry for transferring this data to any other Govt. Agency or SPCB etc. 8
