Environmental Impacts Assessment and Environmental Permit

In the development and construction of the Stanari TPP, all of the environmental impact assessment and environmental permitting conditions required by the effective legislation in Republika Srpska and Bosnia and Herzegovina have been satisfied.

Significant measures include:

  • Obtaining the Resolution on establishing the obligation for implementation of environmental impacts assessment (May 2006)
  • Development of Environmental Impacts Assessment Study (June 2006 – June 2007)
  • Presentation and Public Discussion (June – August 2007)
  • Study Approval (February 2008)
  • Obtaining the Environmental Permit (May 2013)
  • Environmental Permit Extraordinary Audit (July 2015)

An Extraordinary Audit of the Environmental Permit, which was conducted by the competent ministry in Republika Srpska, confirmed that the Stanari TPP conformed to the strict emission limits set out in the Large Combustion Plants Directive 2001/80/EC.

In accordance with the Environmental Impact Assessment, the thermal power plant construction and operation will not bear any significant adverse impact to the environment.

The Stanari TPP currently applies numerous environmental impacts mitigation measures implemented using state-of-the-art technology. The low sulfur content of coal from the Stanari coal deposit further improves environmental outcomes. The desulfurization method applied in flue gases has mitigated the SO2 emissions not only to the standards stipulated by the local legislative but also to the stricter standards defined by the EU Directive 2001/80/EC.

The utilization of a “Low NOx” burner ensures the nitrogen oxides emission levels comply with the EU Directive 2001/80/EC.

The removal of solid matters from flue gases is performed by bag filters with the efficiency of 99, 99%. The Stanari TPP also applies a system for continuous monitoring and controlling of combustion processes and polluting matters emissions.

The application for the renewal of the Environmental Permit should be submitted every five years.

Energy Community

In 2015 the Energy Community Secretariat conducted a full review of the process of developing the Environmental Impact Assessment and issuance of environmental permit for the Stanari TPP.

It concluded that the Stanari TPP had met all the requirements of local regulations as well as relevant EU Directives 85/377/EEC, 2001/80/EC, 2010/75/EU.

Air emissions

Air emissions limit values

The air emissions limit values stipulated by the Environmental Permit:

Parameters (mg/Nm3)

TPP Stanari

200

SO2

200

Solid matters

30

The Stanari TPP applies Continuous Emissions Monitoring system (CEMS) to control the level of air emissions and to optimize coal combustion processes.

Calibration of Emission Measurement

The control of CEMS had been performed prior to the operational commencement of the TPP in accordance with the local regulations and BAS EN ISO 14181 standard with the purpose to implement the calibration process (QAL 2).

The assessment quality for measuring parameters (SO2, NOx, CO, O2, temperatures and flue gas pressure, solid matters concentration) fully satisfied the standard requirements.

Occasional Measurement

The occasional measurements performed within the Stanari TPP by accredited laboratories are summarized as follows:

  • Tests performed in October 2017 with the purpose to measure values of SO2, NOx and solid matters emissions in the air proved that the air emissions had fully satisfied the stipulated limit values
  • Measurements performed in October 2017 to test the air emission values of mercury (Hg), hydrogen chloride (HCl) and hydrogen fluoride (HF) proved that the air emissions had fully satisfied the stipulated limit values
  • Measurements performed in March 2018 with the purpose to test the Stanari TPP operational ability to satisfy the requirements in new the BAT (Best Available Technologies, 31 July 2017) standard in relation to air emissions of SO2 and NOx. These results proved the TPP Stanari may satisfy the stipulated limit values of 150 mg/Nm3 for NOx, 180 mg/Nm3 for SO2, in compliance with new BAT standard and Industry Emissions Directive 2010/75/EU.

The continuous emission measurements performed in the period from the TPP operation commencement has proved that the requirements stipulated by new BAT standard for Limit Emission Values (LEV) for solid matters (10mg/Nm3) was satisfied.
