2.1.1 Narrative
The removal action at Kilauea Pesticides involves removing contaminated soils from two residential yards and constructing a concrete stormwater drainage swale that will eliminate the exposure threat from contaminated soil identified on the commercial property. On July 30, 2012 personnel mobilized to the Island of Kauai, Hawaii in order to begin site work. Site work did not begin until July 31, 2012. During the first week of Site work the focus was on preparing the residential properties for excavation. During the second week of Site work the focus was excavating soils and transporting them to the landfill for disposal. Third week activities involved continued excavation, disposal, backfilling and prep work for the drainage swale. Fourth week activities involved backfilling excavations in residential yards, and prep work for drainage swale. The following daily summaries cover the operating period from August 20, 2012 thru August 25, 2012. There was no work on August 26, 2012.

August 20, 2012; Monday
Weather: Sunny to partly cloudy skies throughout day with no rain. Low 80’s and humid.
Personnel on Site: 1 EPA OSC, 5 ERRS Contractors, 2 START Contractors
On-Site Activities: The ERRS contractor continued loading trucks of stockpiled non-RCRA soil for transport off-site. The final two truckloads (approx. 25 tons) were loaded, transported and disposed at the Kauai county landfill in Kekaha today. The final total for all non-RCRA soils and debris transported to the landfill is 65 truckloads (814 tons). Two final truck loads (approx. 30 tons) of base course were delivered, placed and compacted. ERRS completed grubbing the swale and continues to grade and shape the swale for upcoming concrete work.
START continued active air monitoring and sampling at the site and adjacent properties; as well as documenting site activities in the site logbook and through photo documentation. The final post-excavation home site samples were also collected and submitted to the laboratory. START and the OSC discussed minor design changes to the concrete swale plans to ensure all exposed contaminated soil areas are covered or capped.
August 21, 2012; Tuesday
Weather: Cloudy skies throughout day with moderate rain events. Mid - High 80’s and humid.
Personnel on Site: 1 EPA OSC, 5 ERRS Contractors, 2 START Contractors
On-Site Activities: Nine truckloads of clean topsoil were delivered on-site and ERRS began final grading and compaction at the two home sites. ERRS continued to grade and shape the swale for upcoming concrete work and installed the root barrier between home site 4277 and the commercial property. The ERRS RM, OSC Benson, START and concrete subcontractor representative continued discussions regarding minor concrete swale design changes to ensure some form of hardscaping on all appreciable slopes in DU-10 to prevent possible future erosion of a soil/vegetated cap. At a minimum, concrete will be used in all areas covered by the Honua Engineering plans and possibly extended further on the NW corner of the swale as it approaches the 4277 Aalona Street property (DU-12). Grouted rubble pavement (GRP) or concrete will then be used on either side of the culvert as well as in other areas of the northeast corner of the swale depending on the steepness of the slope.
START continued active air monitoring and sampling at the site and adjacent properties; as well as documenting site activities in the site logbook and through photo documentation.
August 22, 2012; Wednesday
Weather: Cloudy skies throughout day with moderate rain events. Mid - High 80’s and humid.
Personnel on Site: 1 EPA OSC, 5 ERRS Contractors, 2 START Contractors
On-Site Activities: Four truckloads of clean topsoil were delivered on-site and ERRS continued final grading and compaction at the two home sites. ERRS continued to grade, shape and compact the swale for upcoming concrete work and poured a sand base for the above-ground swimming pool at the 4275 home site.
START continued active air monitoring and sampling at the site and adjacent properties; as well as documenting site activities in the site logbook and through photo documentation.
August 23, 2012; Thursday
Weather: Cloudy skies throughout day with moderate rain events. Mid - High 80’s and humid.
Personnel on Site: 1 EPA OSC, 5 ERRS Contractors, 1 START Contractor
On-Site Activities: Five truckloads of clean topsoil were delivered on site and ERRS continued final grading and compaction at the two home sites. Soil compaction test (proctor) was completed in drainage swale today. Test documented approximately 90.8% and 95% compaction. ERRS laid non-woven geotextile in drainage swale to act as a barrier between concrete and soil. ERRS received landscape bids for both residential properties. OSC Benson demobilized from site.
START continued active air monitoring and sampling at the site and adjacent properties; as well as documenting site activities in the site logbook and through photo documentation.
August 24, 2012; Friday
Weather: Cloudy skies throughout day with moderate rain events. Mid 80’s and humid.
Personnel on Site: 1 STATE DOH Representative, 5 ERRS Contractors, 1 START Contractor
On-Site Activities: The state representative from DOH is acting as the governmental agency representative on-site for today and tomorrow, Friday and Saturday. One truckload of clean topsoil was delivered on-site and ERRS continued final grading and compaction of the two home sites. Additional sand was delivered to property to use in the crawl space of of 4277 Aalona Street. Concrete subcontractor began building forms for concrete pour. Because the design of the swale has changed, making the sides of the channel steeper, the concrete subcontractor will need to use shotcrete in the channel and the steeper parts of the swale around the culvert head frame
START continued active air monitoring and reduced sampling at the site and adjacent properties; as well as documenting site activities in the site logbook and through photo documentation.
August 25, 2012; Saturday
Weather: Cloudy skies throughout day with moderate rain events. Mid 80’s and humid.
Personnel on Site: 1 STATE DOH Representative, 5 ERRS Contractors, 1 START Contractor
On-Site Activities: The ERRS contractor continued final grading and compaction activities at the two home sites.
START continued active air monitoring and reduced sampling at the site and adjacent properties; as well as documenting site activities in the site logbook and through photo documentation. START also evaluated the impact that the additional soils in the drainage swale might have on the overall performance of the swale. The evaluation did not uncover any adverse impacts.
