• California Resources Production Corporation "Lathrop Unit A" 7, an idle, <br /> dry, gas well, located approximately one-quarter mile southwest of the <br /> Site. <br /> • Participants Petro Corp. "Lathrop" 1, a plugged, dry gas well located <br /> approximately one-eighth mile south of the Site. <br /> Gas well development can generate brine and hazardous materials. The well on <br /> the Site and those on the surrounding properties were drilled and abandoned <br /> under the oversight of DOGGR. Environmental risks are present with any well <br /> drilling or drilling fluid disposal. Idle wells are considered a particular problem <br /> because they can provide a conduit for contaminants to migrate to drinking water <br /> or the surface (Department of Conservation, 2020). However, no evidence was <br /> encountered to indicate specific contamination affecting the Site as a result of <br /> past gas well operations. <br /> 7.5 National Pipeline Mapping System Database <br /> Live Oak reviewed the National Pipeline Mapping System (NPMS) Public Viewer <br /> on April 10, 2020 for evidence of hazardous materials pipelines within one- <br /> quarter mile of the Site. The NPMS does not depict any hazardous materials <br /> pipelines within the search radius. Local pipelines which are not mapped by the <br /> NPMS may be present in the area, however. Pipeline markers were observed <br /> along the western property line. <br /> 8.0 IDENTIFIED CONTAMINATION SOURCES <br /> The following sources of past, current, on-site, and off-site contamination have <br /> been identified as a result of this investigation: <br /> Identified Contamination Source Evaluation <br /> 1.
