STEEL AUTHORITY OF INDIA LIMITED BOKARO STEEL PLANT Modernization-cum-expansion of Bokaro Steel plant by up-gradation of existing SMS-I(1.306 MTPA), debottlenecking of SMS-II (3.35 MTPA) & existing CRM complex (1.66 MTPA), installation of new kiln of 450 TPD in Lime plant, a new Sinter Plant(3.7MTPA) and Oxygen plant (1250 TPD on BOO basis) without increasing the overall production capacity of 5.77 MTPA hot metal.

PROJECT SUMMARY

1. INTRODUCTION

Bokaro Steel plant (BSL) has already been accorded EC on 16.10.2008 by MoEFCC for expansion of its capacity from 4.0 MTPA to 7.0 MTPA of crude steel vide memo no. J-11011/99/2007-IA II(I). Extension of the EC was accorded for a period of five years w.e.f. 15.10.2013 vide memo no. J- 11011/99/2007-IA.II(I) dtd. 24.01.2014. Further, this earlier EC (valid until 14.10.2018) has been granted an amendment by MoEFCC for modifications in some existing plant facilities of BSL along with reduction of overall plant production capacity to 4.606 MTPA Crude Steel (5.77 hot metal) vide MoEFCC letter F.No J-11011/99/2007-IA.II(I) dated 28.11.2014.

The proposed modifications to the project will be carried out within the existing plant premises of Bokaro Steel Plant which is located in vicinity of BIADA industrial estate of Bokaro Steel City, Sub-division Bokaro of Bokaro District in Jharkhand, at longitude 86°02' to 86°10’ E and latitude 23°38' to 23°42' N. The plant is situated 215 to 243m above MSL gently rolling towards River Damodar, flowing west to east.

In addition to the above, BSL has been granted EC amendment vide MoEFCC’s letter J-11011/99/2007- IA II(I) dated 13.12.2017 for development of an alternate water pipeline system for drawl of raw water from Damodar river. The existing water source, i.e. Tenu Canal, which is also the only source of water for all plant activities as well as township of BSL, is over 50 years old and requires immediate repair as well as restoration works in view of recent breakdowns.

Post EC amendment granted on 28.11.2014, BSL has been progressively installing the different projects of the amended expansion-cum-modernization program, which are presently at an advanced stage of implementation. However, for completion of phase-1 up-gradation of SMS-1 and installation of the new Sinter plant-II of 3.7 MTPA capacity, more time is requested as inordinate delay has occurred because of procedural delays in design & engineering activities as well as site clearance activities necessary for enabling subsequent construction activities for SMS-1 up-gradation as well as installation of Sinter Plant-II.

In addition to the above, only (01) one out of the (02) two 1250 TPD Oxygen plants envisaged originally during the expansion of Bokaro Steel plant from 4 MTPA to 7.0 MTPA (reduced to 4.606 MTPA crude steel later) could be installed. The other 1250 TPD Oxygen plant (BOO basis) has been included in the proposed modernization-cum-expansion program.

It is also proposed to improve the performance of existing steel-making as well as downstream facilities by execution of some of the debottlenecking facilities which will augment the existing facility of steel making at SMS-II from 3.3 MTPA to 3.35 MTPA resulting in increase overall capacity of crude steel to 4.656 MTPA and existing CRM complex from 1.2 MTPA to 1.66 MTPA.

Further, the development of alternate water pipeline system will require more time to complete due to delays in project execution activities. In view of the above, BSL proposes to include the aforementioned activities in the proposed modernization-cum-expansion program.

2. PRESENT PROPOSAL

In view of modernizing and improving the existing facilities of Bokaro Steel Plant, BSL has contemplated the up-gradation of existing units, execution of debottlenecking activities as well as addition of some new facilities in the proposed modernization-cum-expansion programme. The overall hot metal production capacity will not change from 5.77 MTPA as per earlier EC and its amendments

granted thereof. The modifications, up-gradations and capacity enhancements of various units envisaged in the proposed modernization-cum-expansion program of BSL is mentioned below:

3. PROJECT DESCRIPTION

3.1 Site Location

The proposed modernization-cum-expansion of existing Bokaro steel plant will be carried out within the plant premises of existing Bokaro Steel (BSL) plant which is located at Bokaro Steel city, Sub-division Bokaro of Bokaro District in Jharkhand, between longitude 86° 02’ to 86°10’E and latitude 23°38’ to 23°42’ N near River Damodar.

3.2 Land & R&R Issues

No additional land acquisition is required for the proposed modernization-cum-expansion programme of BSL as the proposed modernization-cum-expansion of existing Bokaro steel plant will be carried out within the plant premises of existing Bokaro Steel (BSL) plant. Consequently, no R&R issues are involved.

3.3 Water

Water demand shall be met from the existing water allocated to BSL and no additional water source will be required for the proposed modernization-cum-expansion program. An alternate system of drawl of raw water from Damodar River through pipelines will be developed along with existing Tenu Canal.

3.4 Pollution load, effluent and solid waste generation and utilization

The proposed modernization-cum-expansion of existing Bokaro steel plant will be carried out without increasing the overall production capacity of 5.77 MTPA of hot metal as per earlier EC and its amendments granted thereof. The solid waste generation, effluent generation and the total pollution load will marginally increase due to ~1% increase in overall crude steel production from 4.606 MTPA (CS) as envisaged at EC stage to 4.656 MTPA (CS) as proposed now. The re-utilization/disposal pattern of solid waste as well as effluent management will be done as per applicable rules and statutory guidelines.

3.5 Project Cost Estimates

The estimated project cost for the proposed modernization-cum-expansion of Bokaro Steel plant is approximately Rs. 2276.01 Crores. This broadly covers the cost of Civil & Structural work, Main plant facilities and related environmental protection equipment.
