Risk assessment on Hämeenkyrö municipal solid waste incinerator

Risk assessment on Hämeenkyrö municipal solid waste incinerator contains a structured risk assessment of a plan to build a MSWI in Hämeenkyrö. There will be a public vote related to a city planning decision: whether the municipality should plan an area for the plant or not. The vote will be held in November 19, 2006.

PM_2.5 emissions in Hämeenkyrö

PM_2.5 emissions in Hämeenkyrö

Focus:	Existing PM2.5 emissions from all the sources in Hämeenkyrö.
Scope:	Annual emissions. Emissions from the sources in Hämeenkyrö municipality area only.
Description:	PM2.5 means particles with diameter less than 2,5 µm. Generally the most important sources of these fine particles are domestic combustion and traffic. This is most likely the situation also in Hämeenkyrö which is a town of 10200 inhabitants. Industries and energy production are also important sources. There are some quite large industries and power plants (e.g. M-Real Kyro cardboard factory, Finnforest Oyj sawmill and Kyro gas power plant) that also cause fine particle emissions.
Inputs:	Baseline PM2.5 exposure in Hämeenkyrö, Well-being of the population (smells, comfort, noise)
Index:
Definition:
Unit:	tonnes/year
Result:	The sum of the emissions from all the sources (trying to find some numbers here)

PM_2.5 exposure due to MSWI in Hämeenkyrö

Terhi Y

Focus:	Describes the variables affecting the personal exposure to MSWI-produced PM2.5 (and links the exposure to dose)
Scope:	Exact numerical values would require knowledge of the meteorological, geographical etc. data of Hämeenkyrö area and extensive modeling so not included here; certain concentration assumed and dose calculated from it
Description:	Data needed to evaluate the personal exposure Data needed to model the PM2.5 concentration distribution around the MSWI: The emission produced by MSWI Stack height and location of MSWI in relation to municipality Meteorological data: average (e.g. daily) temperatures, wind speeds and directions, solar radiation etc. Geographical data: vegetation, elevations, town build, lakes etc. ... Data needed to convert exposure to dose: inhalable fraction of PM2.5 concentration of PM2.5 around the person in the locations the person moves in times spend in different locations breathing rate of the person weight of the person ... Also required: the background concentration. Some values available for comparison: Urban US highest PM2.5 concs 20-30 mikrog/m3, concentration in Helsinki over several years 8-11 mikrog/m3, non-urban US concs 1-6 mikrog/m3 (Koistinen 2002). Thus, small Finnish town: maybe 7 mikrog/m3?
Inputs:
Index:
Definition:	D = ((IR)(P)(RF)(ET)(EF)(ED))/(BW)(AT) where D = dose (mg/kg.day) IR = inhalation rate (m3/h) P = particle concentration in air (mg/m3) RF = respirable fraction of particles (dimensioless) ET = exposure time (hours/day) EF = exposure frequency (days/year) ED = exposure duration (years) BW = body weight (kg) AT = averaging time (days)(Schwela ym. 2002)

Marjo

Focus:	Baseline dioxin exposure in Hämeenkyrö inhabitants
Scope:	the daily intake and the adipose tissue concentration of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) in Hämeenkyrö population
Description:	Polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs, "dioxins") are ubiquitously present, stable and persistent environmental contaminants. They are fat soluble and thus tend to bioaccumulate in tissue lipid and in the food chain. Food is the major source for human exposure to dioxins, especially fatty food. In Finland the main source is fish, followed by fats and oils.

Indicator variables

• Decisions related to Hämeenkyrö case
• Possible indicators (optimising variables) in Hämeenkyrö

Well-being of the population (smells, comfort, noise)

Kari Auri

Focus:	Factors or issues affecting peoples living comfortability in Hämeenkyrö.
Scope:	The basic factors, like a noise, smell, social factors, etc., that affect the comfortability of inhabitants in Hämeenkyrö. Some of these factors can be measured and some are based on a experience and/or common beliefs and thoughts of inhabitants in Hämeenkyrö, like in other places where the municipal solid waste incinerator have been planned earlier (in Viljakkala).
Description:	1.The noise: From the building phase of the municipal solid waste incinerator From operation time of the municipal incinerator From the traffic Things that should take account: Comparing the noise from the incinerator to the noise coming from the birds, the traffic and activities in a landfill The incinerator has planned to build in the existing industrial place. What is the present level of the noise in that site? What is the distance from the industrial site to the settlement? The noise disturbs the comfortability of the living 2. The smell: Probable less disturbing comparing it to the dump site. Inhabitants, who live near the landfill, think that the smell decreases the living comfortability a lot. 3. The social factors: Increasing a employment grade Decreasing the value of the property (houses, lands, summer cottages) Fear of the birds (the influenza) 4. Landscape: A minor effect 5. Other things that will not occur with the municipal solid waste incinerator: Diseases coming via the rats or birds? (This is a wild assumption) Hazardous components leaching to the ground water and/or surface water will decrease.(The incinerator processes are controlled and monitored) The inhabitants can pick berries and mushrooms with good feelings, without the fear of the hazardous components coming from the wastesite (like from the landfill).

Effects on economy (esp. gas energy plant)

Effects on economy

Focus:	Factors related how plant affects to economy in Pirkanmaa and Kyrönkoski area
Scope:	10 - 20 years?
Description:	How new municipal solid waste incinerator affects to economy? Waste incinerator is going to be a quite significant employer in Hämeenkyrö. It is also noted that price of gas energy is rising so it might be necessary to build the waste incinerator to guarantee low priced energy for M-real cardboard factory and Finnforest sawmill. Shutdown of either of these factory could be devastating to Hämeenkyrö's economy (employs over 300 persons). Shutdown of gas energy plant is not crucial (employs only 24 people).
Inputs:	Data Persons employed gas energy plant (24 person) starting phase of the municipal solid waste incinerator (50 - 60 person-year) working phase of municipal solid waste incinerator (60 - 70 persons) M-Real cardboard factory (335 persons) Finnforest Sawmill (? persons) Tax incomes directly to Hämeenkyrö directly to Pirkanmaa indirect taxes (Sawmill, cardboard factory and waste incinerator)
Index:
Definition:
Unit:	€ or employed persons
Result:	Worst-case scenario: No waste incinerator or bioplant, shutdown of both factories and gas plant Over 300 person less are employed Best-case scenario: Waste incinerator is builded, both factories and gas plant remains over 70 persons more are employed OK-case scenario: Waste incinerator is builded, both factories remains, gas plant is shut down about 50 persons more are employed

Health effects

Focus:	effects of dioxins and PM2.5 on human health
Scope:	potential short-term and long-term health effects among Hämeenkyrö inhabitants caused by dioxins and PM2.5 originating from the Hämeenkyrö municipal solid waste incinerator
Description:	Dioxins are a group of polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs). 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) is the most toxic PCDD/Fs congener, and it is classified as a known human carcinogen by the International Agency for Research on Cancer (IARC). Health effects related to long-term exposure impairment of the immune system impairment of the developing nervous system impairment of the endocrine system impairment of reproductive functions increased cancer risk (evidence from animal studies, weak carcinogens in humans) Sensitive subgroups: foetuses, newborns, individuals with high fish consumption, individuals working in incineration plants etc. (For health effects related to short-term exposure R↻ ) PM2.5 are fine particles less than 2.5 μm in diameter. Health effects related to short-term exposure respiratory symptoms adverse cardiovascular effects increased medication usage increased number of hospital admissions increased mortality Health effects related to long-term exposure (more relevance to public health) increased incidence of respiratory symptoms reduction in lung function increased incidence of chronic obstructive pulmonary disease (COPD) reduction in life expectancy increased cardiopulmonary mortality increased lung cancer mortality Sensitive subgroups: children, the elderly, individuals with heart and lung disease, individuals who are active outdoors
