Re: Contract modification for Grant X-820322-01-0, Long Term Dissolution Testing of
Mine Waste.
Ms. Whiting:
I am requesting a contract modification, at no additional cost, for Grant X-820322-01-0.
The project was proposed to extend for eighteen months, with an end date of March 31,
1994 specified in the contract. However, as mentioned in the May 1993 progress report,
funding was not finalized until February 9, 1993. I request that the end date be changed to
September 6, > 1994. Although no additional cost will be incurred, the distribution of
expenditures within the initial budget will be modified.
As is indicated in the January 1994 progress report, we have conducted the Wet-Dry Cycle
Test and the Elevated Temperature Test for 112 weeks (a total of 132 weeks when including
the 20 weeks for the WGA project), considerably longer than the 50 weeks experimental
duration stated in the proposal. Water quality analyses described in the proposal have been
completed for the extended duration. Data management and analysis described in the
proposal is presently in progress.
Although data analysis is not presently complete, it is apparent that the lack of agreement
between the laboratory and field results for waste rock is partly due to differences in the
particle size used in the laboratory and field. The importance of particle size on the quality
of drainage from waste rock was an issue raised at the EPA workshop in July 1992
(Predicting Acid Generation from Non-Coal Mining Wastes) and at the International Waste
Rock Modelling Workshop in Toronto (September 29 to October 1, 1992).
Due to the influence of particle size in the present experiment and to prediction of waste
rock drainage quality in general, an experiment was initiated to examine the effect of
particle size on the quality of drainage from two of the waste rock samples examined (RIO,
RK4). A rock similar to RK2 is also being examined in this experiment.
I believe the extension is justifiable for the following reasons.
-------
1. The funding for the project was finalized much later than anticipated when the
original end date of March 31, 1994 was proposed.
2. The amount of data presented on the long-term dissolution tests will be in excess of
twice that proposed.
3. The extension will allow a longer period of record (30 vs 10 weeks) for the particle
size experiment.
In order to affect these changes it will be necessary to reduce funding allotted to equipment
(S3000 alotted initially), supplies ($3900), contracts ($7500), travel ($3916) and increase
funding allotted to personnel ($30,792) and supplies ($3900). (Note: $892 was initially
budgeted for utilities, communications, and printing.) There will be no increase in the total
cost.
If this is acceptable, please send the paperwork necessary to complete the modification to:

Re: Contract modification for Grant X-820322-01-0, Long Term Dissolution Testing of

Ms. Whiting:
In a letter dated March 4, 1994 I requested a contract modification, at no additional cost,
for Grant X-820322-01-0. This modification, a change of the end date from March 31,
1994 to September 6, 1994, was agreed to by telephone, however, we have received no
written confirmation. We were recently informed by Anedia Feaster of the Las Vegas
office that we could not bill for expenses incurred after March 31, 1994. Will you please
contact Phil Pippo with the requirements for completing the modification.

Dear Mr. Hoffman:
Re: Final Report on Long Term Dissolution Testing of Mine
Waste (Grant X-820322-01-0)
Due to unforeseen circumstances, the final report will be
delayed. We only recently received the results of the
analysis of leached solids and are presently incorporating
these results into the report. I am requesting an
extension, at no additional cost, until November 14, 1994.
I will be out of the office this week; if you have any
questions, please contact Jennifer Wessels at 612/296-1051

Thank you.
