Alholma sawmill Situated on the coast of Ostrobothnia near Pietarsaari at the port
of Alholma, the UPM Pietarsaari complex comprises the Pietarsaari pulp mill, Alholma sawmill and UPM Metsä’s Ostrobothnia offi ce. UPM Metsä is responsible for wood procurement to, and mill monitoring, at UPM Pietarsaari and the Alholma sawmill. Wood handling in the mill complex is now the responsibility of Oy Adolf Lahti Xypila Ab, which took over from Fin-Terpuu Oy at the end of 2012.
The most noticeable change in 2012 was the purchase by the Swedish company BillerudKorsnäs Finland Oy of the kraft paper mill which operated adjacent to the pulp mill since 1962. The change of ownership was implemented in the latter half of the year.
A third change took place at the port of Alholma involving the ownership arrangements of the port operator handling ship-ments of UPM products. The previous port operator was Oy Bot-nia Shipping Ab, which, since the change in ownership, contin-ues operations at Alholma under the name of Eurports Pietarsaari Oy Ab.
This environmental report refers to the UPM Pietarsaari pulp mill and Alholma sawmill. Issues pertaining to UPM Metsä are cov-ered in the UPM Metsä statement.

is sold, as before, as pulp stock to the paper mill that is now owned by BillerudKorsnäs Finland Oy. Some of the paper pro-duction is sold to the Walki factory operating in the same facility for further processing.
The Alholma sawmill also experienced signifi cant changes last year in terms of its business structure and operations. The sawmill aims to optimise and maximise its production of sawn pine and spruce. Approximately one quarter of the products undergo fur-ther processing.
2012 saw the introduction of an occupational safety campaign, which has reduced the number of work-related accidents at both the Pietarsaari pulp mill and the Alholma sawmill. Occupational safety is directly related to managing the effi ciency of processes
and minimising the environmental impact of the operations. UPM has also introduced a Clean Run programme at the Pietarsaari facility.
The UPM Pietarsaari pulp mill and Alholma sawmill production lines are responsible for their own environmental issues, which are coordinated and monitored by the UPM Pietarsaari Environmen-tal Manager.
The common goal of the pulp mill and the sawmill is to avoid put-ting further strain on the environment and keeping emissions below the statutory permitted levels while increasing production levels.

UPM Corporate ENVIRONMENTAL statement2012UPM pulp and paper mills
This publication, UPM Pietarsaari Environmental Performance in 2012, is the mill’s appendix to the shared environmental report 2010 for UPM paper and pulp mills. This publication, together with the mill appendices, form UPM’s joint EMAS statement. The environmental report of the UPM pulp and paper mills is available at www.upm.com. UPM’s next joint EMAS statement will be published in the spring of 2014.
The images in this environmental report illustrate the different construc-tion stages of the new effl uent treatment plant in 2012. The fi rst invest-ment phase comprised the construction of a new aeration basin (width 68 m, length 135 m, depth 12 m, volume 110,000 m3), a pumping plant, a compressor room, a pre-sedimentation basin (diameter 60 m) and a belt fi lter press. The pre-sedimentation basin and fi lter press were commissioned in October 2012, and the related aeration basin, pump-ing plant and compressor room were commissioned in May 2013. In the second stage, the current aeration basin will be modifi ed into a containment basin effl uent and an adjacent storage basin for effl uent will be built. Furthermore, the post-sedimentation basin will be modern-ised and a new screen commissioned. All of the equipment included in stage 2 will be commissioned by the end of 2013. The project work-load is approximately 150 man-years. National and local contractors have been very successful in the competitive biddings: the contracts will be carried out exclusively by a Finnish labour force, with virtually all the companies from the local economic area.
Achievement of environmental goals in 2012
The most important long-term goal for the pulp mill is the increase in produc-tion levels without placing any further strain on the environment. UPM has also established environmental goals to be achieved by the year 2020.
At the beginning of 2012, the company decided to construct a new effl uent treat-ment plant in Pietarsaari. The new effl u-ent treatmu-ent plant will be constructed in stages. The new pre-sedimentation basin was opened in the autumn of 2012 fol-lowed by a new aeration basin in the spring of 2013. The autumn of 2013 will mark the second phase, with modifi cation of the current aeration basin into a con-tainment and storage basin.
Completion of the new waste treatment plant will ensure the opportunities for fur-ther development of the pulp and paper mill in compliance with the effl uent treat-ment plant long-term environtreat-mental goals of the mill.
Effl uent discharge volumes from the mill remained at the same level as in the pre-vious year. Emissions into the sea calcu-lated in terms of specifi c emissions remained clearly within the BAT levels. Emissions into the air in 2012 were con-siderably higher compared to previous years. Foreign particles weakening the drainability of lime emerged in the lime circulation as a result of a malfunction-ing device in the recovery line of the mill. Autumn rainfall adversely affected the quality of untreated water, bringing with it foreign particles into the lime circulation and exacerbating the problems caused by the weakened lime drainability.
Sulphur compounds entering the lime kiln due to the poor lime cleaning process accounted for higher levels of sulphur emissions from the mill between the end of August and the beginning of Decem-ber.
The mill received several complaints about noise in 2011 and particularly at the beginning of 2012. In June, sound absorbers were installed in the exhaust pipes of the vacuum system at the paper mill. As a result, the mill did not receive any further complaints about noise for the rest of the year.
Pulp mill
The UPM Group programme, Clean Run, began at the end of 2011 with the aim of improving standards and enhancing environmental performance.
In the spring of 2012, the Clean Run pro-gramme for reporting common emission disturbances was introduced at all UPM pulp mills. In compliance with the pro-gramme, the Pietarsaari mill will also pay even more attention to the reduction of emission levels.
The autumn shutdown saw the successful start-up of the recently completed pre-sedi-mentation section that was constructed as part of the fi rst phase of the new effl uent treatment plant. Construction of the aera-tion basin and pumping plants of the treat-ment plant was also started. They were be commissioned in the spring of 2013. Improvements to the environmental report-ing relatreport-ing to the new effl uent treatment plant began in 2012 and will be com-pleted in the spring of 2013.
Surveys on the recycling of solid waste were initiated. Some improvements in the instructions on waste collection points for regular and hazardous waste were made. The project will be concluded by the end of 2013.
Implementation of the development pro-gramme for saving energy continued.
Goals for 2013
The Clean Run programme continues. The goal here is to increase the number of observations regarding environmen-tal non-conformances so that they can be addressed and rectifi ed in a more sys-tematic manner. The programme does not allow more than two major level 3 envi-ronmental non-conformances at the mill. Construction work on the new effl uent treatment plant will continue until the end of 2013. The goal is to start up the aera-tion basin without disturbances and inci-dental emissions.
The environmental report for the pulp mill will be updated in January 2014. Surveys into the recycling of solid waste will continue. The goal is to reduce levels of waste bound for the landfi ll.
Implementation of the development pro-gramme for saving energy will continue. Alholma sawmill
In the spring of 2012, the staff of Alholma sawmill attended training ses-sions on sorting waste. Recycling ers were renewed, labelling of contain-ers updated and their locations revised throughout 2012.
LED lighting was introduced in the drying plants and outdoor areas in the autumn. The plan is to introduce more LED lighting elsewhere, provided that the experiences from the current LEDs are favourable. A conditions evaluation of the drying plants was implemented during the sum-mer shutdown of 2012.
The water consumption in log irrigation was reduced by modifying the irrigation cycle in the summer of 2012 (the con-sumption level fell by approximately 20%).
Goals for 2013
The UPM Group Clean Run programme will begin at Alholma sawmill. The goal is to record and process all observed envi-ronmental non-conformances.
Thresholds will be installed in equipment rooms to minimise the spreading of any hydraulic leaks.
Improvements will be made in sorting of the waste from the operations and moni-toring of waste management.
In the summer of 2013, the control automatics in the drying area will be updated. The automation will further improve monitoring of energy consump-tion. The tightness of doors to the drying area will be studied during the shutdown. The amount of LED lighting will be increased if their use is shown to have been effective.

EMISSIONS INTO THE AIR FROM PULP PRODUCTION IN 2012 (recovery boiler and lime kiln)
DESTRUCTION OF MALODOROUS GASES, % of time
Emissions into the air
As a result of problems at the chemicals recovery island of the pulp mill, produc-tion levels of electricity were lower than in previous years. As in previous years, the pulp mill had a surplus of electricity merely from the energy obtained from combus-tion of black liquor. The surplus electric-ity was sold to the electricelectric-ity network via UPM Energy.
The pulp mill and sawmill sold bark from debarked wood fi bres and pulpwood to Alholmens Kraft for converting into energy. Emissions into the air measured with the specifi c emission coeffi cients were accept-able according to the BAT* standards.
The emissions remained below the per-mitted levels converted into specifi c emis-sions.
Due to the problems experienced at the recovery island, emissions into the air were higher than for the previous year except for solid particle emissions. Malo-dorous sulphur compound (TRS) emissions and nitrogen oxides were somewhat lower than in 2011. Sulphur dioxide emissions were clearly higher than in 2011. Uptimes and downtimes relating to planned and unplanned shutdowns caused some malodours in areas close to the mill.
Content levels specifi ed in the permits were not exceeded during normal opera-tions at the beginning of the year. How-ever, the permitted level for TRS content was exceeded from the end of August to the beginning of December at the lime kiln. This was due to a malfunction of the green lime fi lter, which considerably dete-riorated the quality of untreated water. As a result of the malfunction, there were plenty of impurities in the lime circulation, which clearly affected the results of wash-ing the lime. When the lime that had not been properly cleaned was burned in the lime kiln, the TRS content of the combus-tion gases exceeded the permitted levels. Emissions of fossil carbon dioxide per pulp tonne produced exceeded the tar-get level, although they were still rela-tively low.
The long-term goal is to achieve a pulp and paper mill free of carbon dioxide. The percentage of biofuels during pulp production remained high as in the previ-ous years, i.e. at 98.4%.
The combustion of malodorous gases in the soda recovery boiler was successful at the beginning of the year and the coef-fi cient of utilisation was high. Because of the high disturbance levels at the end of the year, strong malodorous gases had to be channelled for combustion into the reserve burner more frequently than nor-mal. This caused a considerable rise in the sulphur dioxide emissions from the pulp mill. Strong odorous gases were channelled via the reserve burner 4.4% of the time. The corresponding fi gure for 2011 was 2.9%. Thus, the 2012 fi gure is noticeably higher.
Work on the base of the pre-sedimentation section was well in progress by July. This construction project required about 1,200 m3 of concrete.
This pre-sedimentation section was commissioned in October.

Air quality in the Pietarsaari region Local air quality is continuously monitored at two surveillance points: one is located in Pietarsaari near the town centre, the other in Vikarholmen, Larsmo. Except for airborne particles (PM 10), the impurities remained well below the specifi ed permit guideline values.
Airborne particles exceeded the permitted limit value of 50 μg/m3 on 12 days (the maximum permitted amount is 35 days). Traffi c-related levels of nitrogen oxide were quite high, as in the previous years. The daily permit guideline value specifi ed for malodorous sulphur compounds (10 μg S/m3) was never exceeded at either sur-veillance point. The highest average daily levels of malodorous sulphur compounds recorded were 3.3 μg S/m3 near the town centre in August and 1.6 μg S/m3 in Vikarholmen in June. The highest aver-age hourly levels recorded were 13.3 μg S/m3 near the town centre in August and 23.9 μg S/m3 in Vikarholmen in August.

Water
Untreated water sourcing
UPM Pietarsaari acquires untreated water for mill operations from the Larsmo Lake. Total untreated water consumption at the pulp mill and sawmill was approximately 47,000,000 m3, of which a little less than half was used for cooling operations while the rest served as process water at the pulp mill. The percentage of untreated water used at the Alholma sawmill is neg-ligible; below 0.1%.
Emissions into the sea
The long-term goal is to maintain the 1999–2003 level for effl uent loads in spite of the increased levels of production.
Permit levels were not exceeded at any time in 2012 and the target levels were achieved.
Quantitative levels of effl uent from the mill area remained at the same level as in 2011.

Waste
The UPM Pietarsaari landfi ll is located in the mill complex. Solid waste in 2012 amounted to 18,684 t. The amount was around the same as in 2011. Because of the problems experienced in the recovery process, the amount of green lye sludge transferred to the landfi ll was noticeably greater than in 2011. This was caused by large quantities of lime being used as a fi ltering additive. Towards the end of the year, lime in the lime circulation had to be replaced, which led to a large quantity of lime being transferred for tem-porary storage. The lime will be used in 2013 in lime washing.
Some of the instructions at the collec-tion points for solid waste and hazard-ous waste were improved. In 2013, new guide signs will be installed at the waste collection points in compliance with the new instructions.
55 tonnes of hazardous waste was trans-ferred elsewhere for processing, including 44 tonnes of lubricants and grease.

Accredited verifier Inspecta Sertifiointi Oy (FIN-V-001), has audited the UPM Pietarsaari environmental management system and the Environmental Performance report for 2012 along with information regarding the environmental report for UPM paper and pulp mills for 2012. On the basis of this audit, it has been stated on 3 June 2013 that the Environmental Management System of UPM Pietarsaari and the updated information of the EMAS Statement comply with the requirements of the EU’s EMAS Regulation (EEC) No. 1221/2009.
DECLARATION OF APPROVAL
In 2011 the average temperature (3.0°C) in Kronoby was close to 3.4°C, the average temperature for the 1971– 2000 reference period. The months of January, February and December were colder than average, while the months of March and November were clearly above the average tem-perature. The air temperature from April to July was cooler in Kallan than in Kronoby – as is generally the case.
Total rainfall for the year (744 mm) in Korplax in Kokkola was about 40% higher than normal (521 mm). February, April, May, August and October were particularly wet months. For instance, the amount of rainfall in October was more than twice the normal level for that month of the year.
The heavy rainfall was noticeable in discharges from the Larsmo Lake. Water fl ows were almost twice as great as dur-ing the reference period (1999–2005). The impact of brown lake water containing plenty of humus could be seen in the surface level of the sea throughout the year. The salt content at the water surface was 2–2.5% in the coastal areas, com-pared to 3–3.5% in deeper waters and in the entire water column further out to sea.
Spring fl oods occurred in April and May. Thereafter, waters containing nutrients from the Larsmo-Öja Lake were dis-charged into the sea until the end of the year. The nutri-ent load caused by the effl unutri-ent from the mill complied with the permitted levels. The effl uent discharged into the sea increased the nutrient load most noticeably in the summer. The phosphorus load in the sea was about one third greater than in the previous decade.
In February, the Hästgrundet and Gertruds sluices were closed but the fi shing routes were open. Water fl ows from the end of the year were channelled into the sea mainly through the Gertruds sluice to avoid having to take the water contain-ing humus that would reduce the quality of the water used at the mill.
During the winter, lake and effl uent spread as a thin layer below the ice surface, which makes the surface water brown and lowers the salt content. In the summer, there was a clear difference between the level of nutrients and chlorophyll – i.e. eutrophication – in the inner and outer sea areas. The nutrient levels were higher in areas close to lake and effl u-ent discharge points and shallow areas in the Larsmo archi-pelago, where the exchange of water is poor. In the summer of 2012, sea water close to the lake and effl uent discharge points had relatively normal levels of nutrients, while nutrient levels in the outer sea area were lower than normal. The sum-mer’s highest chlorophyll contents, which are descriptive of the eutrophication of the water area, were recorded close to the discharge points at the beginning of August.
The water quality off the coast of Pietarsaari was also assessed in compliance with the national classifi cation system. The ecological classifi cation system is based on seabed fauna and other biological factors. Many other issues – such as the nutrient content, the depth up to which the water is transparent when the sea is not frozen and the chlorophyll content – infl uence the ecological status assessment. The goal is good water quality.
Separate classifi cations have been determined for water quality in the inner (Ps) and outer (Pu) coastal areas within the Bay of Both-nia. The quality of water in the sea area off the coast of Pietarsaari was classifi ed in accordance with levels and parameters established in the ecological classifi cation. Results from 2012 show that water quality was satisfactory at all survey points closest to the effl uent dis-charge area into the inner coastal area (Ps). By contrast, water qual-ity at all survey points in the outer coastal area (Pu) was classifi ed good. In terms of the seabed fauna, the ecological status of the sea area was deemed satisfactory or good in the inner coastal area and good or excellent in the outer coastal area. The situation remained virtually the same as in the previous year.
The quality of water in bathing areas along the coast by Pietarsaari was classifi ed good based on samples taken. Although results did reveal minor instances of blue-green algae in July and August at a national algae survey point in Ådön, no actual blooming algae was found.
Priority areas in environmental protection
The most important environmental goals of the pulp mill are success-ful commissioning of the new effl uent treatment plant and updating environmental reporting.
Improvement of the energy effi ciency levels at the mill will continue in compliance with the energy-saving agreement.
The sawmill’s focus areas include recycling waste and improving the waste recycling instructions along with optimising energy effi ciency. The environmental parameters for the consumption of raw materials and energy are expressed in total fi gures for the UPM Group in the 2012 environmental report for UPM pulp and paper mills.
