  • Th number of licensed vehicles includes cars, trucks, buses etc and is accelerating faster than the growth of the population as more an dmore pople live in the suburbs and require more cars per household than previously The length of roads in Ottawa is actually greater than the City of Toronto with 4 times the popualtion and a smaller area than Ottawa The estimates of premature deaths due to air pollution have increased from 140- 150 (OMA 2000) to the range 250-300 (OMA 2005 and Toronto MOH 2005) partly because Particulate Matter was added as a cause – and plans are in palce to monitor this pollutant which tends to impact locally and accumulate as opposed to being mixed with the atmosphere as other gaseoius products are, with less health impacts
  • it is notewqorthy that the Enviroemtnal Ass4essment for the East West Light Raail project inclded an assessment ofi the prevailing enviroemnt including air quality. Despite the absence of any actual measurements of air quality in the project area, throught EPA traffic management models (mobility 6) and he use of traffic flow numbers (based mainly on the Origin Detsination Survey in 1995 updated by spot traffic counts), the result for the 56 checkpoints was 47 moderate and 7 poor. The enxt Origin Destination Study is exp[ected to provide updated info on traffic flows and be available in April 2006
  • Pyramid of health effects illustrates that as the severity of the adverse health effect decreases, a larger portion of the population is affected We likely need to rely on severe adverse outcomes (mortality and hospitalization) because administrative records are most reliable and available One approach is to examine non-traumatic morbidity/mortality in the community and use risk coefficients from the literature to estimate what proportion is attributable to air pollution Another approach is to examine local exposures to air pollution and do a quantitative risk assessment (gives predicted risk)
  • Many questions are possible, only a few illustrated here Are cost-effective analysis tools currently available or could they be created to be able to assess the health benefits of various policy options? If we could introduce this type of information at the local level, it could help influence policy in a positive way Currently, analysis of health benefits of policy options is not common at the local level

  • Traffic, Pollution and Health City-wide vehicle emission monitoring plan for Ottawa and Alta Vista Drive pilot project draft – J une 9 , 2006
  • Background
    • are 540,000 licensed vehicles in Ottawa
    • population 850,000 minus under 16 and over 80 (or approx 25%) leaves just over 600,000 or one car for each person
    • Official Plan assumes a population growth of 50% in 20 years - the number of vehicles will also likely grow
    • are 7500 km of road with 100 km of new roads built each year. Annual road spending is $600 M.
    • no road user charges ( gas taxes go to fed/prov and not to roads directly))
    • Only 1 in 5 commuters use transit and they pay about half the total cost of transit ($200 M)through fares ($100 M)
    • Each year air pollution causes 279 premature deaths and direct health costs of $100 M in Ottawa (OMA, 2005; Toronto MOH, 2005)
  • Background -2
    • An assessment of Illness Costs of Air Pollution (ICAP)for the Alta Vista Transportation Corridor (AVTC) as part of the AVTC EA, using the OMA model, showed health impacts of 1 premature death and health costs of $40 K each year (subcontract in 2004 by project consultants, Delcan, to DSS Environmental Consultants)
    • on July 6, 2005 Transportation Committee approved the following motion:
    • "That Public Health measures, including Air Quality, be given appropriate consideration when evaluating alternatives during Environmental Assessments, even allowing for the possibility of eliminating an alternative on that criteria alone, should the public health risks be deemed sufficiently high.“
    • This motion was first applied to the East West Light Rail Transit EA which included the following criteria for option evaluation:
    • a) Local and regional air quality (previously "regional air quality") with the indicator being "comparative assessment of air quality levels for key CAC (CO, NOx, HC and PM) - comparative assessment b) Human health with the indicator being "health effects (OMA)" comparative assessment"

  • Local Air Quality Management Areas (UK) http://www.airquality.co.uk/archive/laqm/laqm.php
    • Since 1997 local authorities in the UK have been carrying out a review and assessment of air quality in their area. The aim of the review is to assist authorities in carrying out their statutory duty to work towards meeting the national air quality objectives. If a local authority finds any places where the objectives are not likely to be achieved, it must declare an Air Quality Management Area there
    • This Local Authority has declared an Air Quality Management Area
    • This Local Authority currently has no Air Quality Management Areas
  • City of York, UK - Real time PM, NO2 monitoring http://www.york.gov.uk/environment/airquality/monitoring.html
    • Air quality monitored at 9 sites, using accurate real time monitoring equipment giving pollutant concentrations per minute
    • City of York in northern England, population 181,094 (2001), area 272 km2 – about ¼ of Ottawa’s pop and 1/10 the area
    • 33 Learian Streetbox monitors to be integrated with existing reference equipment and traffic monitors.
    • Nitrogen dioxide is also monitored at an additional 325 sites using the simpler diffusion tube monitoring method.
  • First Stage Review and Assessment of Air Quality http://www.york.gov.uk/environment/airquality/summary.pdf
    • highlighted potential for the air quality objectives for nitrogen dioxide to be exceeded due to the influence of both traffic and stationary source emissions.
    • further stages of review should include:
    • influence of power stations and other major sources of nitrogen dioxide on air quality
    • data obtained from past and current diffusion tube surveys .
    • Use modelling to predict pollution levels from most heavily trafficked streets and relate current levels of pollution to vehicle flow.
    • real time monitoring equipment in the following locations:
    • roadside junction of the inner ring road with a major radial route into the city
    • roadside area where housing is affected by influence of both the outer ring road, industry and out of town shopping
    • major shopping/tourist area with hourly exposure times of large number of people
    • background location close to the city centre
    • rural background location
    • computer model to predict future pollution levels and identify most effective traffic/ planning measures to reduce pollution. This model should be calibrated using actual real time monitoring data collected in the city.
  • Technical Breach Areas - City of York http://www.york.gov.uk/environment/airquality/Tech_breach.pdf
    • In York the five areas of concern are located on or near to the inner ring road, characterized by their enclosed nature and long periods of congested traffic
    • In each case there are residential properties located within 5m of the kerbside which constitute ‘relevant’ locations for the purpose of Local Air Quality Management.
    • Relevant locations can be defined as outdoor, non-occupational locations (e.g. schools, care homes, hospitals and residential properties) where members of the public are likely to be regularly exposed to pollutants over the averaging time of the air quality objectives.

    • In May 2003, NO2 was measured for 14 consecutive days at 67 sites across the city using Ogawa passive diffusion samplers.
    • Concentrations ranged from 4.9 to 21.2 ppb (median 11.8 ppb)
    • I n multiple regression analyses,
    • * distance from the nearest highway,
    • * traffic count on the nearest highway
    • * length of highways and
    • * major roads within 100 m, and
    • * population density showed significant associations with NO2 (multiple correlation >70%)
    • These analyses confirm the value
    • of land-use regression modeling to
    • assign exposures in large-scale
    • epidemiologic studies.
    • IMPLICATIONS
    • Accurate assessments of exposure to
    • traffic-related air pollution are critical

  • East West Light Rail Env Assessment Project Area
  • GRIMM Model 1.107 Mini Environmental PM Monitoring Station
    • The Grimm 1.107 monitor performs particulate size measurements by 90-degree laser light scattering . Air with multiple particle sizes passes through a flat laser beam produced by an ultra low maintenance laser diode. A 15-channel pulse height analyzer for size classification detects the scattering signals. Due to the lack of a sample heater inlet even aerosols and semi volatile liquid particles can be identified. These counts from each precisely sized pulse channel are converted to mass using a well-established equation and the data is then formatted for USA EPA categories of PM10 and PM2.5. The user can also program several averaging functions.

  • Some Policy Questions of Local Significance Monica Campbell, Environmental Protection Office, Toronto Public Health http://www.irr-neram.ca/about/May%2019%20Workshop/Monica%20Campbell%20talk.ppt
    • How does health burden shift if:
    • Network of surface designated transit lanes introduced?
    • Road congestion pricing is introduced?
    • Bicycle network is created that reduces space for cars?
    • Older vehicles are required to be retrofit or retired?
    • Zoning is changed to reduce urban sprawl?
    • Existing point sources are required to meet health-based air quality standards?
    • Comprehensive energy conservation plan is implemented?
    • Coal-fired power plants are replaced with natural gas?
  • City Monitoring Proposal ( 1 of 2)
    • 1. Obtain 10 monitoring units from Learian Streetbox at $7 K each or Grimm Model 1.107 at $20 K each (cost < $200 K)
    • 2. Install 5 along the 417 east-west between St Laurent and Bayshore at 5 km intervals. Install 2 each on major arterial roads: St Laurent, Hunt Club, Woodroffe, Wellington, Bank, Bronson as well as major collector roads crossing residential areas, such as Alta Vista Drive, Heron Road, Carling Ave etc
    • 3. Obtain hourly data for at least one year from each unit, stored in memory at remote units, transferred via phone line to central PC at monthly intervals
  • City Monitoring Proposal 2 of 2
    • 4. Identify periods when PM 2.5 readings exceed 50 micro gm/m3 and compare relationship between all monitor readings and with MOE AQI station at Wurtemburg/Rideau
    • 5. From results of 2005 Origin Destination Survey, determine relationship between traffic volume and average daily PM reading at monitor sites. Identify additional sites where new readings are needed and surplus old sites where measurements can be adequately estimated from nearby readings. If no surplus sites are identified, obtain new monitoring equipment for new requirements
  • Project Plan - Alta Vista Drive Monitoring Pilot
    • Obtain funding for two monitoring units ($ 7K each)
    • the COMMUNITY ENVIRONMENTAL PROJECTS GRANTS program (which has about $50 K a year available for community sponsored projects that have an environmental thrust).
    • - requires detailed proposal and budget for one year project, noting benefits to local community environment
    • - requires AVDRA to form a project team to oversee project. Contact Mr. Onno Ganderesse, CEPG lead
    • b) Request to Medical Officer of Health , outlining public health hazard from traffic emissions on AVD, city wide monitoring proposal and opportunity to have a pilot project in Alta Vista. Make presentation to Health and Social Services Advisory Committee to obtain support. Contact Dr. D. Salisbury, MOH and Vice Chair, HHSAC, Mr Philip Brown.
    • 2. Identify optimum sites (Heron and AVD?, AVD and Kilborn? Smyth and AVD?) based on likelihood of high pollution episodes during day and year and on known traffic flow patterns (research past transportation projects and traffic surveys)
    • 3. Purchase and install unit, begin data collection in consultation with City Staff. Contact Ms. Natty Urquizo Environmental Management Branch
  • Alta Vista Pilot project- Options
    • Option A (now)- AVRDA expression of support for city wide monitoring network and calling for action (which hopefully would include AVD) - add to existing planned request for Traffic Management Study and send separate request to Medical Officer of Health - can be prepared in a week, sent for action to the Mayor and Hume - would mean 2-3 hours of review and drafting by 3-4 people on AVDRA who are familiar with city processes
    • Option B (due July 06)- formal application for Community Environmental Projects Grant to get two automatic roadside monitor to measure pollution along AVD for a year - funding decisions made annually (fall) out of  $50 K grant budget by grant review committee
    • - carefully prepare application, project plan and budget: 2 people, 2-3 hrs/week for 1-2 months
    • - might take 6 months to get approval (from July- Oct 06) and then another year to watch over the project
    • Option C (ASAP but lasting a year) - informal traffic counts from which one could estimate pollution - give us a good idea of traffic, without any money costs and within a short time - ask for 4 or 5 volunteer &quot;traffic counters&quot; to count traffic over a one hour period during A.M. and P.M. rush hours at preselected points along AVD.
    • - take a count for one minute, repeat 15 minutes later, get hourly flow by multiplying by 60 
    • - could start with a count one day per week for a month then wait 3 months and do it again - this would give us all a feel for where and when the traffic is heaviest and prepare for what else follows (including vest site to have emissions monitor)
    • Option D – do all three, starting with Option A, then C then B in terms of order
  • Next Steps - summary
    • Spring 2006 - Draft Project Plan and obtain funding
    • Summer 2006 - Obtain 10 monitoring stations
    • Xmas 2006 - Identify sites and install equipment, begin measurements
    • Fall 2007 Analysis of PM data for readings above 50 micro gm/m3 (Dec 06 to Sep 07)
    • Xmas 2007 Final report and recommendations (incorporate 1 full year of data) including plan for city-wide traffic management/reduction to eliminate high pollution periods
  • The End Any Questions?
