Division of ~IYids & Geology
In response to the Inspection Report prepared by Tony Waldron at the Division upon completion of the
October 26, 1999 Division inspection, Robinson Brick Company submits [he following weed control plan.
This plan will serve as the basis for diffuse knapweed weed control during the 2000 field season and
beyond as and if required.
Methodology
Areas infested with diffuse knapweed within the DDD mine permit boundaries will be sprayed by a
contractor experience in these matters. The liquid application will consist of I pint Torden/acre and 1
pound 2.4 D/acre. Currently, during the 2000 field season, it is estimated that approximately 20 - 60 acres
will be sprayed.
A contractor will be scheduled [o start spraying during late May or early June, 2000, weather permitting.
The results from [his initial spraying will be evaluated later in [he summer of 2000 and secondary steps, if
necessary, will be taken as required.
During the early spring on an annual basis, Robinson Brick Company will inspect the DDD Mine permit
area to determine if additional spraying or other weed control measures, such as mowing, are required. If a
knapweed problem continues, Robco, will take whatever reasonable steps are necessary [o eliminate these
problems. If, for whatever reason, Robco is not able and/or successful in controlling [he knapweed
problem a[ [he DDD mine, Robco will contact the Division for further assistance.
