Public Comment Period Closed re TZC Permit Applications at Upriver Staging Area

Yesterday was the deadline for public comments re the Tappan Zee Constructors, LLC (TZC) staging area upriver. Here is the DEC’s response to my recent update request. I thought the agency would amend its notice by changing the tense since today is September 19, and the deadline was yesterday. So I did.

And I edited two sentences via red that were grammatically ‘eh’ and corrected a misspelled word.

DEC staff visited the Port of Coeymans after being alerted of possible violations related to work being performed by Tappan Zee Constructors, and directed the company to cease operations immediately.  DEC continues to investigate the situation and will determine appropriate action.  DEC is continuing to review the permit applications.

Below is the notice to extend (omitted word) public comments until September 18, 2014.

Extension of Public Comment Period for the Port of Coeymans located Proposed Bridge Section Assembly Facility for the New New York/Tappan Zee Bridge Project.

Tappan Zee Constructors LLC
555 White Plains Road Suite 400

Application ID: 4-0124-00140/00001

Proposed bridge section assembly facility by Tappan Zee Constructors for the New NY/Tappan Zee Bridge. This proposed assembly facility to be located at the existing Port of Coeymans on the Hudson River in Albany County would accept construction materials mainly by barge and some by truck which are to then be fabricated into bridge sections that are then to be placed on barges for shipment to and installation at the NNY/TZ Bridge site in Rockland/Westchester Counties spanning the Hudson River.

Site preparation includes: 1) demolishing an existing building and constructing the bridge section fabrication facility; 2) dredging to a 12 foot depth by environmental clamshell bucket removing approximately 10,000 cubic yards from a 56,000 square feet area adjacent to the shoreline mooring area; 3) Installation of 102 steel piles 24 inch in diameter to construct 4 parallel finger trestles in shallower water outside the 32 – 34 feet deep main river channel where Sturgeon are mainly found from April to September 1.

Two 13 feet wide trestles with 7 rows of three pilings plus a barge fender spaced 30-35 feet apart are proposed to extend 250 feet into the river and to be used by straddle cranes to offload materials from barges. Two 13 feet wide trestles with 4 rows of three pilings plus a barge fender spaced 30 – 35 feet apart are proposed to extend 125 feet into the river for a slider assembly to load completed bridge sections onto barges. The dredging work is proposed to be commenced no earlier than late September and be completed within approximately two weeks. The pile driving work is proposed to commence no earlier than late September and be completed within approximately 7 weeks.

The proposed assembly facility is scheduled to be operational before the end of 2014. Double walled silt curtains are to be used to enclose the dredging and pile driving areas. Vibratory pile driving will be used. The 102 pilings will be removed at the end of the project in approximately 36 months. Dredge spoil dewatering is to be controlled within a dewatering basin for clean Class A/B material and a barge decant and treatment system for Class C material with discharge limits set for both dewatering methods plus the clean material (Class A/B) is to be re-used and contaminated material (Class C) sent to a solid waste facility.

Permits/regulatory approvals required include: a New York State Department of Environmental Conservation (NYS DEC) Protection of Waters Permit, 401 Water Quality Certification, Stormwater SPDES General Permit and Solid Waste Beneficial Use Determination for the re-use of clean dredge spoils.
