Heidi--

We tracked it down, and the county in question is Pinal County, AZ.

However, while this was a 3-year calculation, it averaged data across

multiple monitors in the area in a way that would be inappropriate for

use in calculating a design value, so the chart should be interpreted

with caution.  It was intended for illustrative purposes only.

3-yr average, 2002-2004

Pinal County, AZ  (between Phoenix and Tuscon) 4th highest Max =

0.074667 3-mo, 12hr W126=  24.3333

Hi Lydia,

Is it possible to get in touch with the lead on the Ozone NAAQS Staff

Paper Chapter 7 to help me find a label for a data point?

If the answer is not available to OMB then that would be the most

efficient answer - I hate to spend days on this

Thanks very much,

heidi

Thank you very much, but my question must have been misunderstood.

I am simply looking for a label on a data point in a publicly available

document (I don't have any questions about how standards interface, what

data is a better reference point, etc)

Who would be able to answer my question about the data point in the

2004-2004 data?  I am just looking for a label on a data point --

Thank you, Erika et al,

heidi

Heidi--

The figure in the staff paper was based on 2002-2004 data, so it's

pretty out of date at this point.  We have done some looking at this

question of how primary and W126 would interface, but now that we have

2005 and 2006 data available, we've been focusing on the 2003-2005 and

2004-2006 periods, which are probably better reference points (although

by the time of designations, things would probably look different

still).   Based on data from these more recent periods, we have found no

counties that would violate a W126 of 21 but meet a primary 8-hour

standard of 0.075.   If you're interested in more specifics, let me

know.

Heidi,

Sorry, I was out of the office today.  As of Thursday afternoon, I

believe Erika Sasser was working out the response.

 Heidi,

 I do not have this information (more ambient data, than modeled), but

have forwarded your question on to the appropriate folks.  If you don't

have an answer shortly, please let me know & I'll see where we are at w/

it.

 Thanks,

                                      county(ies)?

 Hi Pat,

 Thanks in advance for your help. I'm looking for the names of the

 county(ies) that appear to attain the 8-hour standard of 75ppb while

also exceeding W126 of 21 on figure 7-1 on page 7-18 of the Staff Paper

(cut and paste below).  Amy thought that Lydia had sent this to either

her or to Art earlier, but I / we cannot find it.

 I also tried to figure out which county from the attached map from the

proposal, but I'm afraid it was not as easy as "Where's Waldo".

 I appreciate your help;

 heidi
