RE: Proposed 1989 Vegetation Sampling Program, Rockcastle Coal Company,
Grassy Creek Mines, Permit C-81-039
I have reviewed the brief write up concerning vegetation sampling at
Rockcastle Coal Company's (RCC) Grassy Creek Kline. I also discussed the plan
with h1r. Tom Colbert of Inter-Mountain Soils, Inc. (RC C's Consultant) on
July 20, 1989. From the write up and telephone conversation I have formulated
the following comments:
1. In general, the vegetation sampling plan is adequate and commits to doing
things as described in the Colorado Mined Land Reclamation Division
vegetation guidelines and the permit. Standard sampling and statistical
methods will be used.
The reference area will be sampled and statistical comparisons made with
each re vegetated pit. Further, Mr. Colbert will look to see whether any
pits were seeded in different seasons. (i.e. If half of Pit 5 was seeded
in 1984 and the other half in 1985, it would be considered in different
seasons). If this is the case, sampling will be performed within each
area.
The proposed change in cover sampling methods from quadrats (used in
the baseline program) to line-point transects is acceptable. The write
up purposefully does not commit to a specific length of transect line.
However, my conversation with Mr. Colbert indicated that transect length
will be adjusted at the mine site to "best fit" as determined by size of
re vegetated areas. After "best fit" is determined, uniform length will
be used throughout the rest of the sampling. This is acceptable.
Mr. Colbert also indicated to me in our telephone conversation that raw
data will be included in any report submitted to Colorado Mined Land
Reclamation Division. This is necessary and acceptable.
You may want to write a short note that quickly outlines the points of
agreement from Mr. Colbert's and my telephone conversation. Namely, sampling
within each discretely seeded area, determining best transect length on site,
and inclusion of raw data in any reports submitted to Mined Land Reclamation
Division.
