ESS SURVEY NOTES:

1. MULTIBEAM HYDROGRAPHIC SURVEY

PERFORMED BY OCEAN SURVEYS, INC. (OSI)

ON JULY 9-10, 2011 AND CAN ONLY BE

CONSIDERED AS INDICATING CONDITIONS

EXISTING AT THAT TIME.

2. PRELIMINARY HYDROGRAPHIC CONTOURS

PROVIDED TO ESS IN DIGITAL FORM BY OSI.

3. ELEVATIONS ARE IN FEET AND ARE

REFERENCED TO MEAN LOWER LOW WATER

(MLLW) BASED ON BENCHMARK "NY COE

WALL" WHICH HAS AN ELEVATION OF 7.23

FEET NORTH AMERICAN VERTICAL DATUM

1988 (NAVD 88) PER OPUS OBSERVATIONS

MADE BY OSI. THE PLANE OF NAVD 88 IS 2.78

FEET ABOVE THE PLANE OF MLLW AT NOAA

STATION 8518750, THE BATTERY, NEW YORK.

ELEVATIONS WERE DEVELOPED FROM ONE

FOOT BY ONE FOOT BINNED DATA WITH THE

AVERAGE ELEVATION WITHIN EACH BIN

POSTED IN THE CENTER OF THE BIN.

4. CONTOURS ARE IN FEET AND WERE

GENERATED USING "QUICKSURF"

OPERATING WITHIN AUTODESK "AUTOCAD".

5. CONTOUR INTERVAL IS ONE HALF FOOT.

6. COORDINATES ARE IN NEW JERSEY STATE

3) CABLE BURIAL AND TRENCH DEPTH WERE APPLIED

TO THE SEA FLOOR PROFILE TO DETERMINE THE CABLE AND

Re: Bayonne Energy Center Project-USACE Permit No. NAN-2008-01564-M3 Burial Depth Deviations-Dive Investigation Results ESS Project No. P273-027.03

Dear Mr. Tomer:

On behalf of Bayonne Energy Center, LLC (BEC), ESS Group, Inc., submits this supplemental report regarding the burial depth achieved during the recent installation of the north cable between Brooklyn and Bayonne as part of the BEC Project.
