Prince George, B.C.- It has been a little more than two years, but the report on the sources of pollution in Prince George is nearing completion.
Dr. Peter Jackson says the results are preliminary and there will be some tweaking especially when it comes to the contribution from locomotives “ We did the study with the thought locomotives were running 24 hours a day, we now know they only run about 7 hours a day, so when we revise that information, the contribution from locomotives will be reduced.”
He adds that Prince George's air problems aren't the result of increased emissions, rather, by atmospheric conditions which trap the air in the region, "Inversions are like putting a lid on the bowl, trapping the air".
The initial results from the Plaza monitoring system, indicate that for the years 200- 2004, the major contributors are as follows:

Dr. Jackson says the numbers will change as they finalize data, then the report will be handed over to an independent third party for review. That review will likely take about a month, and when that is complete the report will be reviewed again for any possible gaps or errors, and will likely be presented to Prince George City Council in late February or early March.
He also says that since the numbers are from the Plaza 400 site (downtown) the impact of backyard burning or wood burning fireplaces and stoves, may not be fully registered as the equipment isn't in a residential area where such activity is taking place.
The final report will be used to finalize the plans for action in phase three of the Air Quality Improvement implementation plan. The information could also be used by the Ministry of the Environment to make a case for reducing the permitted levels of emissions.

On what basis is this statement being made?
It took this long to get accruate information for locomotives? CN was not very helpful? Why would we trust CN? Why was an on-site survey not conducted similar to traffic studies? Garbage in, garbage out.
