ABSTRACT This paper explores the challenges involved with the recovery of oil from a discharge canal with limited access and high relative currents. In March 1999, a sheen was observed in the cooling water discharge canal of Consolidated Edison's 2.5-million kilowatt generating station in Queens (New York City), New York At the time the sheen was discovered, the entire station had been shut down for several months for a maintenance outage. As the tide rose and fell in the East River, into which the discharge canal emptied, the oil sheen moved in and out of a 1,000-foot long tunnel connecting the generating station to the canal. The major challenges to the recovery and removal of the oil sheen were: (1) the low over head of the discharge tunnel and canal support girders, which prevented getting a skimmer into the tunnel and canal; (2) the high discharge rate of the station's cooling water pump; and (3) skimming the sheen in a 3-to 5-knot current. Consolidated Edison is a member of Clean Harbors Cooperative, L.L.C, which was brought in to remove the sheen. This was accomplished utilizing two JBF Scientific DIP Belt Skimmers, which were set up parallel to the current flow, and deflection booming.

In the years from 1970-1982 52 site studies and monitoring studies have been carried out at major existing and planned power plants. The results from the studies have been used in a planning system for water quality. This planning system, which is water quality related, is described in this paper. An important part of the planning system is the description of size and distribution of excess temperature fields and the related biological conditions. In the biological monitoring, emphasis is placed on the benthic community as more vulnerable to the cooling water discharge. The studies have shown that the excess temperature field within the 1-2° isotherm can produce measurable changes in the benthic community. The temperature effect in the pelagic zone is marginal, however, some effects are seen at sites with a deep water intake of nutrient rich water. Entrainment of fish and Zooplankton can be important in bays and estuaries.
