RE: From staff paper page - which county(ies)?









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pretty out of date at this point.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,

Pat Dolwick

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
