I can't agree with that at all. NOX is not in dispute as a smog causing agent
This statement is wildly inaccurate! What happened in the last year when a leading scientist petitioned Congress to reexamine the NOx conclusions of the EPA, pointing out studies of weekend effect on smog? No dispute! Where have you been? I will leave it to you to do the real research and find the studies - I've posted them in the past. While I don't think you will (because you didn't before posting that statement above), they're out there, ranging from unanswered questions on the validity of one of the cited studies on cancer relationship to particulate matter to pm levels to NOx-VOC to ozone formation relationships. The former is not because they doubt the harmful effect of pm in human lungs, but because one of the early studies cited used a sample of miners, working underground, without adequate ventilation, with diesel engines of 1950's vintage, underground with concentrations of diesel smoke, rock dust, coal dust and other mining pm that were literally a thousand times higher than anything experienced in air breathing humans on the surface. Then the real kicker was revealed - over 90% of the miners with lung cancer in that study had been heavy cigarette or tobacco users for all of their adult lives and most since their early teens.
In spite of these other heavily influencing factors, that study was used as the basis for pm relationships to lung cancer. No attempt was performed to measure the effect of severe lung damage caused by smoking habits, or the relatively poor diet experienced by these miners. We know pm is bad, but to use studies like this, with contaminated data and no validated "norms" in the same environment is inexcusable. Talk about skewed results with other contaminating influences.
When the EPA was questioned about the California basin effect (I believe it was in late 05 or early 06), which directly contradicts their NOx to smog effect stance, their answer was "we don't
think that's what's occurring." THINK? Where's the scientific, conclusive proof?. Much of their data comes from computer models, while real world data contradicts their position every weekend.
Look at this link on pages 40 - 45 and look at the relationship of NOx to smog - and the paradoxical effect that NOx is actually reducing smog formation when measured with VOC activity and cannot reduce smog until a 90% reduction is effected - a goal unobtainable in the next 8 to 10 years, the EPA's timeline for much of their emission compliance. Meanwhile, at the 50% level, reducing NOx is actually increasing smog, hence the paradox.

This is one link - there are many others - it just takes some effort to locate - but the data is out there. Do some research and see if the 300 billion dollar outflow for imported oil is worth the real expected NOx reduction mandated by current EPA rules on diesel emissions. If we could accelerate the adoption of diesel engine vehicles, cut fuel consumption by 25%, cut CO2 by 20% over the next 5 years, while putting NOx regulations at similar levels to Euro standards, it would provide a 25% imported fuel savings, reduce greenhouse gas, and provide a 5 year timeline to study real NOx levels rather than push a favored agenda.
Look at page 46 in the link for this statement:
"Regulators have been stoutly resisting the implications of the findings of the weekend effect. Admitting that NOx reduction would be detrimental to ozone control would be a major embarrassment for both EPA and CARB... CARB especially has been vigorously resisting the findings of independent researchers and offering hypothesis to explain the weekend effect...CARB's views have failed to pass the rigors of scientific peer review. The Journal of Air and Waste Management association(JAWMA) devoted a special section to the studies of the weekend effect...the Journal reviewers rejected CARB's submission." No dispute you say? This is only one example. Show me the research that backs up your claim of NOx not being in dispute as a smog causing agent. If it's your opinion say so, but don't attempt to pass it off as fact.
This isn't the only dispute of CARB and EPA findings. Do the research and you'll see the negative effect of politicians posing as EPA managment can have on national emissions policy, our health and financial well being.
