It’s going to be tough for 80 Series to meet these standards

Sorry maybe I am missing something is this for the Denver area or state-wide?

 

[kerrye]

All areas which require emissions tests I believe

So this appears to apply only to areas currently subject to the AIR Program? (first paragraph of section A)
Nor do I see a pub or effect date later than 2015.
Is this the newest doc available?

Come up the hill, no emissions testing.

My apologies. This is probably not the most recent document. AircareColorado says standards are tightening 1/1/22 and I had been searching to determine what they are. I thought I had found them but appears I am mistaken. If anyone else can find the new standards please enlighten me.

Here’s the announcement about the upcoming changes but for the life of me I can’t determine what they are:

Here’s the AirCareColorado announcement

Right. There is something afoot but it's difficult to nail down for some reason.
Specifically 'when-where'.

 

[kerrye]

I think I finally found them. Not sure how to interpret the changes. Looks like no changes for 1994 or 1995 but changes to other years.

 

[LandLocked93]

WOW!!
Am I reading that right??
PAIR delete lives on! - No visual inspection [to qualify] for certification.
Bit of a win on cats too - no verification of cali-compliance required of replacements [to qualify] for certification.
There's more too for 94-96 model years.

Did I see somewhere someone say 35in tires and they just do an OBDII test…??

Here’s where I found those changes:

Some of the changes don’t seem to make sense. It looks like some HC levels changed from 2 to 2.06. Or 1 to 1.05. That doesn’t seem right since the rest of the limits are whole numbers.

Great, I’m exempt!

 

[kerrye]

Someone said that on another thread of mine. But AircareColorado says otherwise on their website. But apparently it has happened.

Change in percentage? (in the right direction given the other changes)

FWIW I had to replace my cats with ones that had a California certification in order to pass last time. Pretty sure I still barely passed. This doesn’t bode well.

Those numbers are grams per mile I think. Unless they’re changing to a different standard of measurement.
