RE: Edna Strip Ftine, permit No. C-80-001, Seed Mixtures for
Non Top-Soiled Areas
As you know, Carl Mount and yourself of CMLRD met with Terry Crowner,
Dave Beverlin, and Brian Godtarek of Pittsburg and Midway Coal Company on
February 15, 1989 to discuss possible changes in their seed mixtures for
non-topsoiled spoil areas that they are having sane problems with in respect
to vegetation. Specifically, plant cover has remained sparse on the
non-topsoiled areas even though they have been reseeded two times with the
approved seed mixture. P b M's feeling is that the use of different (most
likely introduced) grass and forb species on these areas would improve plant
cover.
I referred them to Rule 4.15.2 - Use of Introduced Species and 4.15.6 - Field
Trials and pointed out section 4.4.6 of the Edna Mine permit document (a short
description of a study done comparing topsoiled vs. non-topsoiled area
revegetation). In order for the Division to consider the use of introduced
species on the non-topsoiled areas, P b M would have to demonstrate:
1. Which species were growing the best on the spoil areas that
they have already tried to revegetate. This would be done
through the use of cover data on the areas obtained this caning
summer;
2. Which species have performled best on the study plots on the
P & M Mine site which Terry Crowner knew about and thought he
could get some other data on;
3. Which species have performed best on other areas through a
literature review or other written evidence from studies done
on similar disturhed situations.
It is my opinion that, with the evidence above, the Division could consider a
seed mixture change through the minor revision process. However, once they
have the information, please encourage them to contact us prior to submittal
of the minor revision.
