A Presentation by
JHARKHAND STATE POLLUTION CONTROL BOARD
On
25TH June, 2019

2. WHY CEMS
• As per the 1st Revised Guideline for CEMS,
August 2018, CEMS is to Installed at –
1. All the 17 categories of highly polluting industries
along with Bio Medical Waste Incinerators and
Hazardous Waste Incinerators.
2. Installation of online PM10 Analyzer for major air
polluting industries including Railway Sidings,
Coal/ Iron ore/ Bauxite mines/ Hard Coke units
has been made mandatory.

6. CAUSES FOR DATA
UNAVAILABILITY
• Selection of Technology
• Correct installation of CEMS (Isokinetic
sampling points)
• Quality Assurance and control
• Calibration Requirement
• Data Handling System

7. ACTION TAKEN BY JSPCB
• Minimum 85% shall be transmitted to JSPCB
otherwise JSPCB may issue Show Cause
notice, requiring immediate feedback on
corrective action.
• Environmental Compensation shall be
implied on the industries by JSPCB if they
fail to take stringent actions for the
compliance of faulty data/irregularity of data
within period of 1 month.

8. SELECTION OF AN
ANALYSER
• Based on temperature and moisture content in
the stack.
• Dew point of sample gas and corrosive gases.
• Dust content in stack
• Range and maintenance of analyzer

9. CALIBRATION OF CEMS
• The continuous Particulate Matter
monitoring system (PM-CEMS) shall be
calibrated at different operational loads
against isokinetic sampling method at the
time of installation.
• Calibration shall be done once in 06 months
by empaneled laboratories by CPCB using
standard reference methods and at a
frequency specified.
Refer: http://cpcb.nic.in/ocems1/

10. CALIBRATION OF CEMS
• For Gaseous Parameters:- The instruments/
analyzers shall be calibrated with respect to
their functioning, drift, linearity detection limit,
output, operating temperature and other
relevant parameters before installation
• The industries shall ensure tamper-proof
operation of CEMS devices
Refer: http://cpcb.nic.in/ocems1/

11. WAYS TO DEAL WITH
EXCESSES EMISSIONS
• Average emission for initial 30 minutes shall
not be considered during the plant start-up or
batch process.
• Values recorded during calibration/
preventive maintenance shall not be
considered for Exceedance.
• Incase of Exceedance value, SPCB may issue
Show Cause notice, requiring immediate
feedback on corrective action.

12. WAYS TO DEAL WITH
EXCESSES EMISSIONS
• If, the emission quality continuously exceeds
the prescribed norms by 10% of standard and
for duration of 1 hour then
1. Industry shall immediately inform the SPCB
about the control measures initiated by them.
2. Incase of failure, closer of its operation.

13. CEMS DATA FOR REGULATORY
ACTIONS
Data performance
: How much data
received at server
Performance: How
much and for how
long the value
exceeded
Generation of
Performance
Report & Identify
the defaulters
Action Framework:
Action taken as
per Guidelines

14. ACTION FRAMEWORK BY JSPCB
Action
Period of
observation
(No. of Weeks =
X)
Criteria Based
on Data
Performance
JPSCB will send - Show Cause
letter to the client
1 Week Industry is one of 5
with lowest positive
data availability and
mean data
availability is< 85%
OR
Industry has zero
data availability for
at-least X weeks in
the past 4 weeks
JSPCB will send another Show
Cause letter to client and meets
the client & CEMS vendor
2 Week
JSPCB will send the Show Cause
letter for the third time and
conduct a site visit and verify the
stack sample
2 Week
JSPCB Officials may issue
Closure and Environmental
Compensation shall be imposed.
4 Week

15. How could CEMS be made effective?
DATA GENERATION
Industry sends
well-calibrated data,
with high uptime
DATA ANALYSIS
Data quality checked
Summarized to ROs in
an actionable manner
- High instantaneous
emissions
- Clear weekly
summaries
DATA APPLICATION
ROs take measures on industries
as per protocol using CEMS
Data.
