Your queries contain overlapping ranges, so I am giving you the data in this table...

|--------------+------------+----------| | RANGE | # REPORTS | # FORMS *| |--------------+------------+----------| | < 10K lbs |202 |92 | |--------------+------------+----------| | 10K - 25K lbs| | | | |3,595 |882 | |--------------+------------+----------| | > 25K - 300K | | | |lbs |8,548 |1,392 | |--------------+------------+----------| | > 300K lbs | | | | |14,818 |2,304 | |--------------+------------+----------| | Total | | | | |27,163 |2,927 | |--------------+------------+----------|

* Not additive; a form may appear in several ranges

Note: Each IUR Site has its own Form #; therefore # Sites = # Forms

# Forms (Sites) with all reports have production < 25,000 lbs. : 107

If you have any questions or need anything else, please let me know.

Hi, Darryl -- I just heard back from my contractor, after they had a chance to look at the numbers you sent me for 2002 reports and forms. In order to do the analysis for the EA (the 10,000 lb reporting threshold option), they need the following additional information: Page 2Fw Follow-up on 2002 IUR database query

The number of reports and sites for the following three production volume ranges:

1)The number of reports with production volume between 25,000 lbs and 300,000 lbs (we can't calculate that segment by subtracting what you gave us) 2) Number of sites (even if there are errors/duplicates) for reports with production volumes that are: a) between 10,000 lbs and 25,000 lbs b) between 25,000 lbs and 300,000 lbs 3) Greater than 300,000 lbs

We do not need numbers of forms for these ranges.

Also, if this is doable, we also need the number of sites for which ALL reports submitted were for chemicals manufactured below the 25,000 lb threshold. This would allow us to estimate how many additional sites would need to complete the complete Part I as a result of the 10,000 lb threshold option.

Thanks very much -- Wendy
