Chronology of communications with SECL w.r.t. use of ash in backfilling of mines

S.No Date Details Remarks

1. 31.03.2015 JSPL letter to SECL to continue backfilling of Gare

Pelma IV/1 using ash from DCPP

-

2. 02.04.2015 Reply from SECL stating that flyash filling will not be possible

-

3. 24.04.2015 JSPL/ JPL letters to MoEF requesting to allow continuation of use of ash in backfilling of mines pursuant to requests of SECL to exempt them from use of ash

-

4. 13.05.2015 Letters to MoEF requesting to withdraw “exemption of backfilling using ash” granted to SECL for Gare Pelma IV/1 and Gare Pelma IV/2 & IV/3

Exemption to SECL was granted by MoEF&CC vide letter dated 16.04.2015

5. 11.08.2015 Request letter to SECL to use ash from TPP of JPL to

back fill Gare Palma IV/2 & IV/3 Coal mines

-

6. 27.11.2015 Letter to MoEF requesting to permit continuation of use of ash for backfilling of Gare Pelma IV/1

-

7. 09.12.2015 JPL request letter to SECL reiterating to use ash

from the TPP of JPL to back fill Gare Palma IV/2 &

IV/3 Coal mines

-

8. 18.12.2015 Reply from SECL intimating that since litigation

w.r.t. Gare Pelma IV/2 & IV/3 is in process and

hearing of Writ Petitions W.P.(C) 3001/2015 &

W.P.(C) 3002/2015 have been concluded and

judgement reserved, SECL shall wait for the

judgement for any further decision

As long as SECL is a custodian

it is mandatory on the part of

SECL to comply with the

provision of Ash Utilization

notification while

undertaking back filling of

mine

9. 30.07.2016 JPL’s letter to Chief Secretary, Chhattisgarh with a

request to direct SECL to use ash from JPL’s TPPP

while undertaking back filling in Gare Palma IV2 &

IV/3

-

10. 20.08.2016 JPL’s request to CMD, SECL, Bilaspur to use the ash

generated from JPL’s TPP in backfilling of the Gare

Palma IV2 & IV/3 coal mine.

-

11. 17.09.2016 Reply, in relation to Gare IV/2 & IV/3, from SECL

intimating that following points to be considered

before taking decision on the aforesaid subject:

The issues are irrelevant and

SECL cannot run away from

its responsibility to comply

SECL is only custodian of the mine

The matter is subjudice

Unavailability of Overburden

Dual responsibility of operation

Modified EC does not stipulate fly ash backfilling

with the Ash Utilization

Notification

12. 16.10.2016 JPL reply, w.r.t. backfilling in Gare Pelma IV/2 &

IV/3, to SECL that the concern raised are irrelevant

and not in line with the Ash Utilization Notification

-

13. 26.10.2016 JPL letter to Chairman & Member Secretary

Chhattisgarh Environment Conservation Board

Raipur and Joint Secretary ( HSMD) MoEF New Delhi

with a request to direct SECL to use fly ash in line

with Ash utilisation ,1999 ( as amended up to 2016 )

of MoEF from JPL’s TPPP while undertaking back

filling in Gare Palma IV2 & IV/3

*NOx calculations during EIA were done as per World Bank norms of 400 mg/Nm3 for Phase I

and 9kg/ ton of coal for Phase II. The proposed NOx calculations have been estimated

considering new standards for Thermal Power Plant of 300 mg/ Nm3.

#The above estimated emissions after proposed change of fuel is theoretical and the actual

emissions will be much less as evident from the existing emissions below.
