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. Fifth week involved placing a concrete cap on the the drainage swale. The following daily summaries cover the operating period from August 27, 2012 thru September 1, 2012. There was no work on September 2, 2012.

August 27, 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, 1 START Contractor
On-Site Activities: The ERRS contractor focused on placing fabric and sand in the crawl space underneath the structure on home site 4277. Non-woven geotextile fabric was placed over all exposed soils in crawl space and then approximately 2 inches of sand was placed over fabric. The level of sand was selected to minimize any adverse impacts to accessibility and still protect against exposure. The concrete subcontractor continued to build forms and lay wire mesh in the drainage swale in anticipation of pouring concrete on horizontal surfaces on Wednesday afternoon. OSC Duncan arrived on site.
START is no longer collecting air samples but continues active air monitoring and at the site and adjacent properties; as well as documenting site activities in the site logbook and through photo documentation.

Weather: Sunny to partly cloudy skies throughout day with a couple rain events in the AM. Temperatures remain in the low 80’s and humid.
Personnel on Site: 1 EPA OSC, 5 ERRS Contractors, 1 START Contractor
On-Site Activities: The ERRS contractor continued final grading and compaction activities at home site 4277. The concrete subcontractor finished building forms and laying wire mesh in the drainage swale.
START assisted the OSC in providing written notification to the county engineer regarding changes made to the design of the drainage swale cap. START also continues to document site activities in the site logbook and through photo documentation. The OSC , RM and START meet with the property owner at 4277 Aalona Street and discussed the landscape design.
August 29, 2012; Wednesday
Weather: Cloudy skies throughout day with several short but significant rain events. Low 80’s and humid.
Personnel on Site: 1 EPA OSC, 5 ERRS Contractors, 1 START Contractor
On-Site Activities: Due to some changes in landscape preferences, clean soil was excavated and stockpiled on-site. The ERRs contractor loaded a truckload of clean soil which was disposed in the county landfill. The ERRS contractor also continued final grading and compaction activities at home site 4277. The concrete subcontractor began pouring concrete on the horizontal services of the drainage swale. Although rain events slowed down the process, the subcontractor was able to finish the pour. The surface was giving a rough finish using a stiff broom. Next week the concrete subcontractor will place shallow blocks on the concrete surface to further discourage trespassers.
START continues active air monitoring at the site and adjacent properties; as well as documenting site activities in the site logbook and through photo documentation.

The concrete subcontractor applied “shot-crete” on all vertical surfaces within the drainage swale footprint.
START completed all real-time air monitoring as well as documenting site activities in the site logbook and through photo documentation. OSC Duncan demobilized from the site.
September 1, 2012: Saturday
Weather: Sunny to partly cloudy skies throughout the day. Low 80’s and humid
Personnel on Site: 5 ERRS Contractors, 1 START Contractor
On-Site Activities: The ERRS Contractor completed laying gravel in front of home site 4277 and in the drainage swale area where there was no concrete cover. Where appropriate, metal caution tape was placed on top of soil prior to gravel cover. Gravel was compacted in placed.
