RE: Emergency Repairs Primary Crusher
Dear Mike3
On Wednesday, September 14, we shut down operation of our Telsmith 50" X
60" primary crusher due to apparent bearing failure on the main drive shaft.
This unanticipated breakdown has caused an emergency situation for South Coast
Asphalt due to the following facts. The main drive shaft needing repair is 3'
X 15' and will necessitate replacement of four bearings. Bearings and seals
this size are not shelf items and therefore not readily available. We anitici-
pate that obtaining the necessary parts and completing the repairs will take
from three to four weeks. At the time of the breakdown we had approximately
ten days supply of crushed rock in inventory for production of asphalt concrete,
for delivery as road base or crushed rock products. Because of the necessity
to continue production to meet commitments to our customers, we have rented and
installed a portable crusher as a temporary replacement for the machine under
repair. We have place the temporary crusher in close proximity to our existing
primary crusher, within the city limits of Carlsbad. The tempoarary crusher is
smaller than the one under repair, therefore we anticipate that we may have to
operate the crusher longer hours to achieve a minimum production rate to feed
the rest of our crushing plant. Presently, it appears that it will be necessary
to operate the temporary crusher from 6 AM to 10 PM, Monday thru Saturday to
meet commitments to our customers.
The replacement crusher began operation on Thursday, the 22nd for, what we
anticipate will be, a four week period. Concurrently, we have applied for, and
been granted an emergency variance for the temporary crusher by the San Diego
Air Pollution Control District. This variance is subject to the same dust con-
trol requirements that are contained in the Permit to Operate issued by the
SDAPCD for the permanent primary crusher and plant.
The only possible effect that this emergency situation may have on our
neighbors to the north is that the noise from the operation of the temporary
crusher may be more discernible due to its more exposed location.
moniter, with a sound meter, in the evenings, the sound from this operation at
various locations in Costa Serena, and make every reasonable attempt to att-
enuate any increased sound levels generated by the temporary installation.
