Freshwater In-Situ Oil Burning Air Monitoring
This report documents the background, planning, preparation for a series of in-situ burning (ISB) tests using Alaskan North Slope (ANS) crude oil in fresh water. This study assessed the use of a small, unmanned aerial system (sUAS) with gas monitoring equipment to track the chemical compositions and particulate spread of a smoke plume during an ISB event. The Special Monitoring of Applied Response Technologies (SMART) protocol methodology currently recommends downwind personnel deployment of ground-based DustTrak sensors to assess potential exposure to gases and soot from the plume. Ground-mounted terrestrial Light Detection and Ranging (LIDAR) equipment was also used to assess the density and particle size of the smoke plume during testing.The sUAS monitoring system, SMART protocol DustTrak sensors, and LIDAR were compared to assess their efficacy for monitoring ISB smoke plumes, assessing risk, and improving the safety of responders and localized populations. The U. S. Coast Guard Research and Development Center (RDC) conducted this work with material and technical support from the U. S. Army Cold Regions Research and Engineering Lab, the U.S. Coast Guard National Strike Force and the U.S Environmental Protection Agency. The intent is to provide responders with information to consider in deciding whether ISB is a feasible action to mitigate the threat of spill in a freshwater environment.
