Response to June 30 Adequacy Review (as amended)

emphasize that temporary irrigation is to be employed for the purposes of
establishment, and not to the level where artificial soil moisture conditions will
encourage rooting where roots would not be viable in the long-term.
The operator commits to using watering techniques to the extent reasonably
necessary to establish the proposed revegetation plan. This is a performance
standard, reflected in Rule 3.1.10(5). As noted under the response to Exhibit G,
below, the final reclamation process will allocate up to 30,000 gallons per day to
irrigation. It is anticipated that a portable water tank could be located on the site
and, with a pump, used to feed drip lines that would provide soaking moisture to
the plant growth medium around woody plants. A spray mechanism on a water
truck and/or sprinklers fed from the water tank would supply area coverage on an
as-needed basis to provide soaking moisture to grass seed.
Exhibit G -Water information
36. The applicant has indicated that the only water requirement for this project is for dust control
and possibly for irrigation of re-vegetated areas in the early stages of plant growth. The applicant
has estimated the initial daily water requirement to be 30,000 gallons per day. In conformance
with Rule 6.4.7(3), please clarify whether this estimated daily water requirement pertains to the
initial development stage or the mining phase of the operation. Also, please provide an estimate
of the daily or annual water requirements for irrigation of tree and shrub transplants during final
reclamation.
To clarify the application document, the "initial estimate" of water requirements
applies to all phases of work for the purposes of Rule 6.4.7(3), including site
development, mining, and reclamation. The stipulation in the initial application,
that washing of aggregates will not take place on the site, reduces the need for
water on the site to that needed for dust suppression and irrigation of certain
reclaimed areas. Dust suppression will generally concentrate water applications
to internal haul roads, aggregate stockpiles, and pre-moistening of rock in the
active quarry face. At any given stage of mining, 30,000 gallons/day will provide
a sufficient budget to actively suppress dust. The 30,000 gallon budget is also
sufficient to cover all phases of reclamation, up to and including the final
reclamation of all 40 acres. The selected species for revegetation are suitable to
the low water budget typical of the area; an average import of 30,000 gallons/day
is more than ample to meet the appropriate 3 gallons per square foot water
budget indicates for such species in standard landscape water budgets.
Small amounts of water for drinking and hand washing will also be imported to
the site and are included in the estimate of 30,000 gallons/day. This initial
estimate will be adjusted as needed to conform with other performance
standards expressed in this application and review process -for example,
additional water may be imported to enhance plant establishment.
