Dr.Peter Jackson  details the results of the report in a presentation to the PG AIR  Annual General Meeting.
 
Prince George, B.C.- The final report on the four year study of Prince George Air Quality indicates the top four contributors to PM2.5 at the Plaza 400 site downtown are:
1.      Permitted users (industry 18%)
2.      On road dust (mobile sources, 15%)
3.      Locomotive sources 12% and
4.      Commercial restaurants 11%.
 
The report indicates the  results for restaurants seem to be unusually high, so that will be revisited. Residential heating accounted for 8%. 
 
These results differ from the study released in 2007 which used a different method to track pollutants. That report listed the top three offenders as:
·       pulp emissions
·       wood-burning emissions
·       mobile (including vehicle) emissions
 
The new report also suggests the PG Air Improvement Roundtable, may want to take another look at its goals. The target set by PG AIR is to reduce PM 2.5 annual concentrations to the annual 5ug/m3 by 2016. The study says all major source categories would have to have a 75% reduction in order to reach that target. It suggests perhaps a 65% reduction is more realistic.
 
Report Co -author, Peter Jackson, says the science may not be perfect, but the numbers in the new study are the best they have to work with.
 
The report helped form the draft plan for Phase Three of the Prince George Air Quality Management Plan. That draft carries 47 recommendations for action in five sectors, Industry, commercial, transportation, residential and research & education.
The draft plan will be up for public consultation and input at a special session set for December 8th at 6 p.m. in room 208 at the Civic Centre.
 
Some of the recommendations include:
Industry:
-review and implement operational procedures to reduce emissions
- new industry in the community to locate in suitable areas
-Continuous improvement of regulatory protocols for permitted facilities
Commercial:
-reduce emissions from space and comfort heaters,
-Reduce idling at drive- thrus
-Reduce PM emissions from commercial restaurants
Transportation:
-Reduce road dust thru improved City street sweeping practices
-Encourage winter tire use to reduce quantities of road aggregate needed
-Education strategy to reduce vehicle idling
-Improve transportation infrastructure that results in decreased emissions
-Encourage alternative transportation
Residential:
-reduce emissions from recreational vehicles which create   fugitive dust
-reduce residential emissions from improper use  or burning of the following:
               Open burning, BBQ-ing, food smoking, recreation fires,
Research, Education Other:
-hire clean air ambassador
-hire air quality coordinator

Good job. On the research part, an environmental model of polution can be constructed and the visualisation run on the HPC machines.
Research, Education Other:
-hire clean air ambassador
-hire air quality coordinator

More city staff with big pay and little or nothing still done about air quality. Why hire more people who can't do anything?? City Hall staff will soon outnumber the rest of us.
Good to see the final results of the report, now hopefully we can fix some of the problem areas and quit finger pointing. Unlike the comment above I think a coordinator would be useful.
As a long term resident of PG who has not plans to move I am very thankful that air quality is being addressed and I thank everyone who is working on trying to improve the air for all us. I should stop here,....BUT

I am a bit concerned about using the Plaza 400 site as the place to measure air quality. Not a lot of people live downtown. Lots of people work there but their air quality is highly dependent on their office building HVAC system.

I think they should focus on the data they get from the locations where people live and kids go to school (Gladstone and Lakewood). I have absolutely no data to back up my claim but I bet the % of particulate in those areas coming from road dust & parking lot maintenance is a lot higher than 15%. It may be better for the health of our kids to encourage the big box stores and malls to sweep periodically in the winter when possible rather than focus on trains and pulpmills????
Good to see CN rail named as a significant contributer.

I believe it is still the case, please correct me if I am wrong but the diesel locomotives burn is not the low sulfur fuel we are required to use. For example compare the particulate emission from a 10 year old diesel truck designed for higher sulfur diesel to that of a 2010 diesel truck designed for low sulfur diesel. Notice the soot cloud is not as common. The sulfur is just one piece of this but generally that's the end result with improved fuel standards.

Although CN is federally regulated they need to be at this table with a plan on how they are going to clean up their emissions locally.

Unfortunately if CN does not want to take part they don't have to. Municipal or Provincial government cannot tell a Federally regulated business how they will conduct business. Not sure what the answer is other than ask the Federal Minister responsible to get this significant industry to the table to help improve our air shed.

Overall this study appears far more sound than previous.

Permitted users and Trains are a bigger concern for me personally because many communities have road dust and do not have a serious air quality problem. Also the fact that potentially a percentage of the road dust problem could be attributed directly to those permitted users. For example the hauling of chips and logs potentially introduces allot of additional dirt mud and road turbulence to the road surface. Don't get me wrong I am in no way saying the trucks should not be on the road. I am saying the permitted users play a significant role that may be beyond what is initially apparent in the overall problem. I'm not a hippie -not that there is anything wrong with that ;-)- I'm a realist.

As another said I'm a long term resident and will continue to be. I hope my kids can tell story's to theirs one day about how around 2011 the air started to significantly improve because the community worked together to end the antiquated handling of the air shed.

Have a great afternoon
Wood burning ain't the source?
I say get rid of all those dang stoves in the bowl, they're a nose sore!
I say give industry and the trains, (Hmmm, I thought trains were industry too) more of our tax dollars to clean up their pollution. Isn't that the Liberal way?
They are talking about industry like Lakeland mills (heat exchanger). The City wants to use it too. That will be a big boost to our poor air.
