Clarkstown Announces Update on
of Noise and Dust at Tilcon, West Nyack
Supervisor Alex Gromack has announced
that the third 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 and the second in September 2007.
During the week of December 17,
2007, noise and dust monitoring was conducted again at various locations in
proximity to the Tilcon West Nyack site.
The most recent report concludes that the maximum noise levels were
reduced at all five residential locations.
The frequency of noise levels above the county decibel standard went
down from 88% to 50% at the Crusher
Road location, from 88% to 75% at the Casper Hill Road
location and from 63% to 25% at the Tamar
Drive and Storms Road location. Therefore the average of the noise levels
above the county decibel standard was reduced for all 5 homes. In addition, a comparison to the previous
dust study conducted in October 2006 and September 2007 indicates significantly
lower dust levels for the more recent monitoring period.
Supervisor Gromack said, "We are pleased to see
improvements in noise levels in the residential areas and a decrease in dust
levels; however, there is still more progress to be made. The town will meet with our independent
engineering firm and Tilcon to review testing procedures and possible
Under an 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 also obtained a building permit from
the town for the renovation of the Storms
Road house and has started work on the interior
and exterior of the home.
Tilcon is finalizing plans to relocate the plant below
ground level. In December 2007, they
submitted a formal application to the Planning Board 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. Their application is going through the Technical
Advisory Committee (TAC) and Planning Board process.
Supervisor Gromack said, "We feel it is important for
Tilcon to continue to address any residential concerns resulting from their
mining operation. The agreement we
reached with Tilcon specifies a timeline with goals and we will continue to
Another round of monitoring dust
and noise at the quarry will be conducted later this year.
