PES-51 ™
Morris J. Berman No. 6 Oil Spill
 
San Juan, Puerto Rico
United States Coast Guard (USCG) -Strike Team and contractor equipment deployed for the various response activities were decontaminated using PES-51™ at three major decontamination centers in San Juan, Puerto Rico. A variety of application methods were used including direct wiping, pump sprayers, airless sprayer and pressure washers. PES-51™ was specified for decontamination usage by the USCG -Federal On-Scene Coordinator (FOSC) due to its cleaning and phase separation efficacy and waste stream minimization characteristics. PES-51™ was used to clean a variety of response equipment including: contaminated booms, sea fences, sea skirt, pumps, skimmers, hoses, tools, Oil Spill Response Vessels (OSRV), pleasure boat hulIs, USCG and Marine Spill Response Corporation (MSRC) Vessels, and a variety of vacuum trucks. At some decon stations, rinse waters were recycled and wastewater minimized. Primary decontamination activities were conducted by Foss Environmental Services (FES) and Crowley Environmental Services with local sub-contractor  assistance.

MSRC Virginia Responder

Norfolk, Virginia  After the Marine Spill Response Corporation (MSRC) test of the Recovered Oil System (RCO) using a combination of No. 6 and No.2 fuel oil with emulsion chemicals, it was cleaned using PES-51™. The entire system including the four 1,000 barrel tanks, piping and oil/water separators were decontaminated with PES-51™ using a variety of application methods including pump sprayer, airless sprayer, and circulation of PES-51™/oil cleaning solution throughout the RCO piping. Afterwards the piping was flushed and rinsed with ambient temperature seawater, to a sheen free condition.

Barry Oil Company -Pipeline Spill

McGrath Beach, California
A crude oil pipeline leak resulted in an oil spill which impacted an irrigation pond, adjacent wetlands and a 14-inch in diameter, half-mile long runoff control pipeline which carried the crude oil to the ocean. The responsible party and its prime response contractor used PES-51™ for all response equipment decontamination (including OSRV hulls, pumps, booms, tools, etc.). PES-51™ was also used to clean the oil impacted runoff control pipeline using the PES-51™ cleaning solution circulation and fresh water flushing technique. Response equipment was cleaned in a lined pit using pump type and airless sprayers followed with freshwater pressure washer rinses and hand wiping.
