smooth brome, with a relatively minor weedy component. This grassy patch may comprise approximately 20% of the non-brushy flats west of the office. "East Flats" The small non-brushy area east of the office and pazking azea contains a relatively large patch of a low growing, spreading Polygonum (knotweed), which has lazgely prevented the establishment of desirable vegetation over a third or more of the azea. The remainder of the East Flats area supports a modest stand of seeded perennial grasses and forbs, along with vazious annual and perennial weeds, and some cheatgrass. Considerations and Recommendation The "West Flats" and "East Flats" areas described are excessively weedy and support a generally poor stand of desirable vegetation. Weed control efforts and reseeding would appear to be warranted. Interseeding "without restarting the clock" pursuant to 4.15.7(5)(8) would not appear to fit this case, because the purpose of treatments would be to replace existing stands that are dominated by species which do not support the approved post mine land use. It is not entirely clear to me, but is probably doubtful that the operator would be able to make the "less than five percent of the acreage reclaimed in any one yeaz" demonstration, with respect to treatment and reseeding of the weedy areas [pursuant to 4.15.7(5)(b)], since the flat azeas were appazently revegetated several years after the portal slopes were revegetated. The most logical approach may be for the operator to coordinate treatment and reseeding of the weedy areas in conjunction with grading and seeding of the adjacent office and pazking azea, with the entire "flats" area to be managed as a single unit with respect to ultimate bond release. I would suggest that you request the operator to provide a remedial treatment plan for the weedy flats azeas, in conjunction with the grading/topsoiling/seeding plan for the office and parking area.
