Monitoring programme - Linköping power plant

• Recipient monitoring (air, water)
• External inspections (boiler, CFC-inst. etc.)
• Reporting
• Annexes (drawings of
  boilers, emission points, treatment plants and
  coal storage area)

• General information
• Description of the plant and its emissions
• Permit conditions
• Environmental monitoring
• Process monitoring (instructions and recording)

The plant and its emissions

• Waste and hazardous waste disposal
• Noise
• Fuels (amounts, types and storage)
• Chemicals (urea for NOx reduction, boiler and
  water treatment chemicals)

• Location
• Coal-, oil-, wood boilers and turbines
• Air emission sources and its control
• Description of water system and water treatment

Air emission monitoring of coal boiler

• Continuous monitoring of nitrogen oxides, sulphur
  dioxide, dust, oxygen, and carbon monoxide
• Once a year as part of external inspections are
  dinitrogen oxide, ammonia and phthalates
  monitored
• Lead, cadmium and zinc once a month on a
  collective sample and during inspections

Air emission monitoring of oil boiler

• Continuous monitoring of nitrogen oxides, oxygen,
  and carbon monoxide
• Once a year as part of external inspections are
  dinitrogen oxide, ammonia and dust monitored
• Sulphur is monitored in oil at every delivery

Monitoring of condensate from wood boiler

• Continuous monitoring of ammonium nitrate, pH and
  water flow
• Twice a year and in addition as part of external
  inspections are suspended solids measured

Monitoring of water from ash handling, cooling
and oil storage

• Suspended solids, pH and total sulphur is
  monitored in water from ash separator once a year
• Flow (continuously) and total extractable organic
  compounds during water pumping from oil storage
  by spot samples
• Daily average flow of cooling water during
  periods of power generation (May-Sept.)

Process monitoring

• Recording of operational parameters
• Recording of calibrations and maintenance
• Recording of disturbances in the production of
  importance for the environment

• Instructions for operation and maintenance of
  boilers
• Instructions for operation and maintenance of air
  emission control equipment
• Instructions for calibration of monitoring
  equipment

Environment quality monitoring

• Joint ambient air quality monitoring through the
  Association for Air Quality in the County to
  which the company contributes
• Water recipient quality monitoring through Motala
  Ström Water Association

External inspections

• Measurement of combustion and air emission
  parameters on all boilers and spot samples on all
  waste waters
• Report on all inspected objects. Results,
  evaluation, defects and planned changes

• Inspection of installations and records. Changes
  in production etc. which influence emissions are
  recorded
• Monitoring of noise is made
• Inspection and calibration of monitoring equipment

Reporting

• Regular reporting every three months not later
  the 2 months of the end of the period
• Reporting on inspections within 2 months after
  inspection
• Reporting on disturbances and accidents
  immediately
• Yearly reporting within 2 months after end of
  year

Yearly reporting

• Monitoring results and emissions, accuracy of
  installed monitoring equipment
• Comments on permit conditions and possible
  actions
• CFC-reporting
• Signature

• General information
• Description of operations
• Permits and permit conditions
• Environmental report
• Production time and conditions
