Re: Public Inquiry, Golden Eagle Mine
Permit No. C-81-013, Basin Resources, Inc.
Dear Mrs. Prijatel:
This letter is to update you on the status of your inquiry as to the possible hydrologic effects of
mining at the Golden Eagle Mine on the two springs on your property at Rancho Escondido, Unit
No. 4, Lot 39.
First, the question of which map correctly depicts the location of your property has been
resolved. The Division's letter of July 26, 1994, asking you for clarification of the matter, was
based on an out-of-date map. The new map submitted by Basin Resources and the map that you
had submitted, in your letter of August 25, 1994 to this Division, are in agreement as to the
location of your property.
Second, as part of the Division's normal inspection schedule, I visited your property on
September 27, 1994, accompanied by Ralph Lopez of Basin Resources. Two areas were
identified as possible springs. The consultant for Basin Resources was informed of these two
locations and they will include them in the annual spring and seep survey that is submitted to this
Division. In this survey, the nature of the two springs will be described and the two springs will
be monitored for selected physical and chemical parameters. Any changes in water quality and
quantity will be documented.
Third, Basin Resources has submitted an analysis, contained in Exhibit 6 of the permit applica-
tion, that contains a prediction that there will be a drawdown of one foot in the water table
elevation at a distance of 2.1 miles from the perimeter of mining. Larger dEawdowns are
expected closer to the mining operations. This drawdown is due to the pumping to the surface of
the water in the underground mine workings, causing the water table in the surrounding area to
be lowered. Pumping will cease when mining ceases.
The location of the two springs is more than 2.1 miles from the current perimeter of mining.
However, the source of the two springs is unknown, so it is also unknown what [he distance is
from the mine perimeter to the source area. According to the mine plan, the location of the two
springs will be within 2.1 miles of the mine perimeter sometime in the middle of 1996.
