The 2010 CEAA Screening Study for Terry Fox Road Part B contains a manditory section that summarizes the effects of the project on air quality.
Amazingly, the road is assessed as having No Significant impact due to tailpipe emissions and resultant smog and Greenhouse Gas (GHG) effect!
The US Environmental Protection Agency, however, measures vehicle emissions based on the distance driven. By creating more roads, our cities expand the opportunity for vehicles to drive (generating more GHG in proportion to the length of the road) and create a disincentive for using public transit – roads are more convenient.
By investing in Terry Fox Drive (TFD), the City has also created an opportunity cost of $47+ M by not putting the same amount of money into public transit. As an example of the impact of this opportunity cost, currently there is some concern over the cost of student bus passes that are now manditory. An expenditure of less than $5 M is probably sufficient to allow all students to ride the bus for free. The $47 M being spent on the road would have enabled students to ride the bus for free for over 9 years!
The City should have disclosed that TFD will result in a net total annual emission of 90,324 Tonnes of GHG per year.
The calculation for this is:
- GHG increased by volume of traffic x amount of time of traffic on road.
- Use avg traffic volume x 24 hrs x avg GHG emission per hour per vehicle
- Assuming peak to average ratio is 10:1 and that peak hour volume is 2 hours x morning & afternoon
- US EPA: light duty vehicle (incl passenger car but not SUV and miniVANs) = 337 gCO2 per mile
- US EPA: SUV, miniVAN, pickup trucks are approx 1.3 x worse
- US EPA: Combined Cars & Trucks = 1.13 x passenger = 1.13 x 337 = 380.81 gCO2 per mile driven
- 380.81 x 1.6 = 609.296 gCO2 per km per vehicle = 0.6 kg CO2 per km
- TFD is 4.8 Km long = 0.6 x 4.8 = 2.88 Kg CO2 per vehicle
- Using unconstrained modal split disclosed in the 2004 EA Traffic Study of 8950 vehicles per hour (In+Out) 8950 x 2.88 = 25776 Kg CO2 per peak hr
- 8 x 25776 / 1000 = 206.208 tC per day from peak plus 16 x .1 x 25776 / 1000 = 41.2416 tC non-peak per day
- 206.2 + 41.24 = 247.44 tC per day x 365 = 90,315.6 tC per annu
- GHG absorption decreased by loss of forest cover due to clear-cutting for the road:
- Use hectares removed by road times GHG absorption per hectare
- 4.67 ha Dry-Fresh Sugar Maple-Ironwood Deciduous Forest
- 0.34 ha Dry-Fresh White Ash-Hardwood Deciduous Forest
- 5.61 ha Fresh-Moist White Pine-Hardwood Mixed Forest
- 0.37 ha Young Deciduous Forest
- 4.67 + 0.34 + 5.61 + 0.37 = 10.99 ha
- 10.99 x 0.75 = 8.2425 Tonnes Carbon absorbed per year
- According to David Suzuki Foundation, other GHG removal per hectare of forest is 60 kg/ha = 0.06 t/ha
- 0.75 + 0.60 = 1.35 GHG per ha
- 10.99 x 1.35 = 14.8365 Tonnes of GHG per year
- Use hectares removed by road times GHG absorption per hectare
Net change in GHG = 90315.6 + 8.24 = 90323.84 Tonnes per year
The analysis used in the previous section is based on the City of Ottawa’s own traffic study statistics which are based on unreasonable traffic volumes. Nonetheless the City was obligated to disclose the impact based on the numbers that they used to justify the road.
The Canadian Environmental Assessment Agency (CEAA) was also obligated to ensure that the disclosure was accurate. How could they have accepted an error of over 90 MegaTonnes of GHG emission?
We deserve much more responsibility and accountability from our public servants at both the Municipal and Federal levels!
