All design values are based on five years of data,
except those marked with "*" which are based on three, or"#" which are based on four.

The threshold is 85.0 ppb unless the number of qualifying days is less than 10,
in which case the threshold is adjusted downward as needed to qualify 10 days,
to a lower limit of 70.0 ppb, after which the acceptable number of days is reduced to as low as 5.

Monitors outside Ohio with old and new design values below 84.5 ppb are omitted from the above list.

5247 coarse grid rrf's calculated; 3483 cells are uncalculable.
The highest rrf is 1.1577 at ( 63, 95); the lowest is 0.6477 at ( 79, 83)

rrf calculations attempted for 4 nests totalling 3816 cells, over 173 days; 3816 cells calculated, 0 uncalculable.
minimum fine-grid rrf = 0.684 in nest 1 at ( 1, 2) in coarse cell ( 53, 46); maximum fine-grid rrf = 1.224 in nest 1 at ( 3, 2) in coarse cell ( 53, 47)
Be alert! The world needs more lerts!
