GUILDERLAND — Developer Gregory Wolanin was fined by New York State’s Department of Environmental Conservation for working with heavy machinery in a certified trout stream.

The stream runs alongside a property that Wolanin owns, One Pinnacle Place in McKownville, off McKown Road.

Wolanin was fixing existing bridge abutments without a permit, according to Rick Georgeson of the DEC’s Region 4 public information office.

A permit would have included measures to be taken to mitigate any adverse environmental impacts to the aquatic habitat, Georgeson said.

Wolanin was fined $750 for work done on July 13 and had to take steps to protect the stream, Georgeson said.

Wolanin did not return repeated calls from The Enterprise.

The classification of the stream next to One Pinnacle Place is C(t), Georgeson said, which means that it supports fisheries and may support a trout population. The fear about unpermitted work in the bed or bank of protected streams, he continued, is that the work could damage aquatic habitats by, for instance, “covering sensitive trout spawning beds with sediment that can smother their [trout’s] eggs.”

The steps that he was required to take were to immediately stabilize and seed all disturbed areas and install a silt fence on the southern end of the western abutment until vegetation is established, according to a copy of the schedule of compliance that was sent to him that The Enterprise received from Georgeson. The DEC also specified in the schedule of compliance that no wet, fresh concrete or leachate is to enter the water at any time.

If Wolanin plans to do any further work that will disturb the bed or the banks of the stream, he will need to get a permit from the DEC, Georgeson said.
