Transit Mix Concrete Co.
Response: The revegetation summary in Exhibit L has been updated. The seed mixes match
those listed in the tables found in Exhibit E. The seed mixes (stems/acre mix) has been included
at the bottom of the revegetation summary calculations.
12) The applicant's response to Item No. 58 of the Preliminary Adequacy Review states that
Exhibit E has been revised to include a table listing the acreage associated with each revegetation
type, and that revegetation types with multiple species, lists based on water availability, also
have the acreage specific to each species list. However, Table E-2, Reclamation Areas by
Planting Type, includes 0 acres for Wet Shrubland and 0 acres for Dry Riparian. Please provide
an estimated acreage for all revegetation type mixtures. Additionally, the acreages accorded to
each revegetation type in Table E-2 do not correlate with those given in Exhibit L, revegetation
summary. For example, Table E-2 shows that 81.14 acres will be revegetated to Mixed Conifer,
while Exhibit L shows that 57.97 acres will be revegetated to Mixed Conifer. The values are
inconsistent for all revegetation types. Also, according to Table E-2, a total of 195.82 acres will
be revegetated, while Exhibit L costs account for revegetating a total of 139.51 acres. This is a
difference of 56.31 acres. Please make the necessary corrections to Table E-2 and/or Exhibit L to
eliminate these contradictions.
Response: Table E-2 has been revised to estimate the acreages for the Wet Shrubland and Dry
Riparian planting areas and to include revegetation of the "Mining Related Area"(which is not
planned for disturbance). The reclamation areas equal 239.03 acres.
Transit Mix has provided the reclamation bond estimate for mining through Phase 3, and Transit
Mix commits to updating the reclamation bond calculations prior to starting Phase 4. The
disturbance through Phase 3 is limited to 159.92 acres; therefore, the reclamation costs have been
calculated using this area. The conditions at the end of Phase 3 are different from those at the
end of the quarry operation(Phase 6) and the total reclamation area and the acreages associated
with each revegetation type will also be different.
EXHIBIT G -Water Information (Rule 6.4.7)
13) The applicant's response to Item No. 66 of the Preliminary Adequacy Review states the
operation will require an average of 4-6 truckloads per day using a 6,000-7,000 gallon tanker
truck. If the quarry were to operate 365 days/year, that would give a maximum of 15.33 million
gallons/year(42,000 gallons/day x 365 days). Is this value correct for mining phases of the
project? Please provide an estimate of the project water requirements including annual volumes
for the development, mining, and reclamation phases of the project.
Response: The volumes estimated are for the operational phase. Transit Mix anticipates that
less water will be required for development and reclamation than for operations. Water
requirements for development are estimated to be approximately 4,300,000 gallons per year(1-2
truckloads per day). Water requirements for site reclamation are estimated to be 2,200,000
gallons per year(1-2 truckloads per day). Once the slopes are regraded and seeded/planting, no
long-term watering is expected to be required.
