ENVIRONMENTAL PROTECTION AGENCY

ORDER OF THE BOARD (by Mr. Dumelle)

In response to a Motion for Clarification filed by the Environmental

Protection Agency dated December 7, 1972 the Board clarifies its intent

as follows. The numbering below corresponds with the listing of the

Motion.

a)

The term 1Tcontinuous monitoring stations means stations

which will operate automatically around the clock and which

will yield a permanent record (strip chart, punched tape,

computer tape, etc.) and which have a sampling frequency

and sensitivity sufficient to detect puffs of SO9 of short

duration and intensity all sufficient to cause plant damage

as well as long term low levels which might cause decreased

yield.

b)

The uplant damage” referred to is to be considered as theoretical

plant damage since what is desired to be known is whether the

potentiality exists for plant damage from SO2

in the future even

assuming

it has not occurred in the past.

c)

Plant damage is to be considered as applying to planted

crops such as corn, soybeans and those plants actually

found in the area in farmers’ home gardens. OrnamentaL-

shrubs

and flowers, unless raised in a commercial enter-

prise, shall not be considered. What is desired to be

known is whether SO2 levels exist sufficient to cause

theoretical plant damage (see ‘b’ above) on plants

actually planted in the area as described above.
