Clarkstown Announces Update on
Monitoring of Noise and Dust at Tilcon, West Nyack
Supervisor Alex Gromack announced
that the second round of tests for the Tilcon-West Nyack Quarry is
complete. The Town has an agreement with
an independent engineering group to monitor dust and noise, collect daily
weather data and provide a summary of findings associated with mining
operations at Tilcon. Tilcon had
previously agreed to reimburse the town for the costs of these field tests. The first field monitoring program was
administered in October 2006.
During the week of September 17,
2007, noise and dust monitoring was conducted again at various locations in
proximity to the Tilcon West Nyack site.
The report concludes that from the 5 residential locations observed for
the October 2006 and September 2007 weekly monitoring periods, the frequency of
noise levels above the county decibel standards went down from 100 % to 88% at
two of the homes and maximum noise levels were reduced at 3 of 5
homes. Therefore the average of the noise levels above the county
decibel standard was reduced for all 5 homes.
Supervisor Gromack said, "We are aware that at times
noise and dust levels may be above recommended levels but most importantly we
are seeing improvements in the residential areas and there is still more
progress to be made."
Under the agreement with the town the following
improvements have been made by Tilcon: the dust control system was upgraded,
all conveyors on the finish side of the plant have been covered, a new larger
water truck is in service for dust control, all screens have been changed from
wire to rubber, crusher plates have been changed from steel to ceramic, one of
the buildings was completely insulated with noise reduction panels, and one of
the crushers was enclosed with a noise mitigation structure.
Tilcon is finalizing plans to relocate the plant below
ground level. In December 2007, they
submitted to the planning board a formal application for the new entrance road,
which will reduce traffic, and further construction of a berm, which will
mitigate noise and improve the appearance surrounding the plant. Tilcon also submitted a building permit
application for the renovation of the Storms
Supervisor Gromack said, "We recognize by law the
right of Tilcon to function as a mining operation in our town, but we feel it
is important for Tilcon to address any residential concerns resulting from that
operation. The agreement we reached with
Tilcon specifies a timeline with goals and we will continue to monitor
A third round of monitoring dust
and noise at the quarry was conducted in December 2007 and the results and
report are expected in two months.
