NOKOMIS 5-W. National Contingency Plan Product Bulletin
Technical Product Bulletin: this concentrated liquid non-hazardous cleaner can be used to remove oil from equipment, shoreline areas, beaches, and tidal rock surfaces.
-
NOKOMIS 3-F4. National Contingency Plan Product Bulletin
Technical product bulletin: this dispersant used in oil spill cleanups may be applied directly from drums by fitting them with a "T" connection and pumping fresh or salt water across the junction, which pulls dispersant into water stream and onto spill.
-
NOKOMIS 3-AA. National Contingency Plan Product Bulletin
Technical product bulletin: this water-based dispersant used in oil spill cleanups is most efficient when agitated and mixed thoroughly with the oil and water. It can be applied at full strength by using a direct connection from pump to drum.
-
NATURE'S WAY HS. National Contingency Plan Product Bulletin
Technical product bulletin: aka MICRO CLEAN or POWERCLEAN, this surface washing agent used in oil spill cleanups should be applied full strength to surfaces such as shorelines and beaches, pressure sprayed into cracks/crevices, and scrubbed well.
-
NATURAMA G3 A-5. National Contingency Plan Product Bulletin
Technical product bulletin: this surface washing agent, used in oil spill cleanups, may be applied by any method (drum pump, pressurized spray applicator, brush, or aqueous wash tank) depending on surface and the type and viscosity of oil/contamination.
-
NALE-IT. National Contingency Plan Product Bulletin
Technical product bulletin: this surface washing agent for oil spill cleanups is applied by pressure sprayer to pit closures, surface hydrocarbon spills, compressor stations, pipeline and flow line leaks, well head and tank farm leaks, and highway spills
-
MUNOX SR®. National Contingency Plan Product Bulletin
Technical product bulletin: this bioremediation agent (microbiological culture) for oil spill cleanups can be applied to surface water, beaches, marsh, or wetland. It is effective even on heavy petroleum compounds, and does not damage marsh or wetlands.
