Inc. (“Fugro-McClelland”) 880 to obtain an independent assessment of the environmental<br />

conditions in the former concession area. Taken together, the HBT AGRA and Fugro-<br />

McClelland audits provide the most accurate assessment of the environmental impacts<br />

that may have resulted from TexPet’s operations.<br />

In October 1993, after completing its fieldwork, HBT AGRA prepared a twovolume<br />

draft Environmental Assessment Report. It concluded that there was little<br />

evidence of widespread or unconfined contamination either in the surface or subsurface<br />

soil. 881 It also found little evidence of subsurface contamination migration beyond the<br />

boundaries of the production stations and wellsites, because the impervious clayey soil<br />

of the area largely prevented contamination from moving away from the pits and<br />

ponds. 882 With respect to water, HBT AGRA found little evidence of contamination of<br />

groundwater (i.e., subsurface water) that might serve as a drinking water supply. 883<br />

Furthermore, HBT AGRA found that, as the Consortium’s Operator, TexPet had<br />

adhered to standard industry practices of the time related to environmental<br />

management. 884 In the end, it estimated a cost of US$13,274,000 to remediate spills<br />

and pits at the 22 production stations and 163 well sites that it had assessed. 885<br />

In 1992, Fugro-McClelland performed both a quality assurance/quality control<br />

(“QA/QC”) assessment of HBT AGRA’s work 886 and a parallel audit of environmental<br />

880<br />
