2.1.1 Narrative
The removal action at Kilauea pesticides involves removing contaminated soils from two residential yards and constructing a concrete stormwater 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 began on July 31, 2012. During the first week of site work the focus was on preparing the residential properties for excavation. The following daily summaries cover the operating period from July 31, 2012 thru August 4, 2012. There was no work on August 5, 2012.
2.1.2 Response Actions to Date
July 31, 2012; Tuesday
Weather: Sunny skies throughout day with intermittent rain showers. Low 80’s and humid
Personnel on Site: 1 EPA OSC, 4 ERRS Contractors, 1 START Contractor, 3 Subcontractors
On-Site Activities: The ERRS contractor subcontracted a plumber to determine the location of the cesspool/septic system and assess its operating condition at home site 4277. The property owner had complained that the system was not working properly and may need to be replaced. OSC Duncan felt that if the system needed to be replaced, the property owner should have it done while the property was excavated. OSC Duncan also wanted to assess the condition of the system prior to any removal activities so that EPA would not be responsible for any pre-existing problems with the system. The plumber was able to locate cesspools (there were two) and confirm that incoming and outgoing drain lines were clear and operating. The property owner was unaware that there were two tanks. The clean out of the second cesspool was buried and had never been seen by the property owner. As a final step to determine the integrity of the cesspool/septic system, the ERRS contractor will locate the clean-out for the second tank and arrange to have it pumped out.
The ERRS contractor also subcontracted a tree remover contractor to remove several large trees throughout the site. Tree removal activities will continue throughout the week. The ERRS crew worked on preparing both residential properties for excavation. Smaller trees and shrubs were cut down and hardscape (concrete pavers, rocks and stones) and potted plants were moved onto pallets so that they could be relocated during excavation and backfilling activities. The START contractor collected photo documentation and recorded site activities in a logbook.
August 1, 2012; Wednesday
Weather: Sunny skies throughout day with intermittent rain showers. Mid 80’s and humid
Personnel on Site: 1 EPA OSC, 4 ERRS Contractors, 1 START Contractor, 3 Subcontractors
On-Site Activities: The tree removal subcontractor continued removing large trees on the two residential properties. The Kauai Island Utility Cooperative arrived on site to discuss moving a power pole that is in the middle of the back yard of the home site 4275. The utility company will need access to the rear of the property on Friday, August 3, 2012. The ERRS contractor continued preparing the two residential yards for excavation activities. This included activities mentioned in Tuesday’s summary as well as fence removal and taping plastic over the windows and doors of the home site 4277. The ERRS subcontractor also began work on an access road from Aalona Street to the rear yard of home site 4275. OSC Duncan and START met with the owner of a nearby preschool to secure access for placing samplers and monitors on their property. START also worked on writing a Site Workplan. The Site Workplan was started many weeks ago and will be completed at the end of the week. Lisa Thompson moved out of her residence (4277). She will reside in temporary housing until the excavation and backfill activities have been completed.
August 2, 2012; Thursday
Weather: Partially clear skies throughout no rain showers. Mid 80’s and humid
Personnel on Site: 1 EPA OSC, 1 STATE DOH Representative, 4 ERRS Contractors, 2 START Contractors, 3 Subcontractors.
On-Site Activities: The tree removal subcontractor continued removing large trees and assisted the ERRS contractor with some smaller shrubs and vegetation. The ERRS contractor completed the access road to the rear of home site 4275 from Aalona Street. OSC Duncan and START worked on a training that they will present to the landfill county employees tomorrow morning. An additional START member arrived on-site today to assist with the air monitoring and sampling. OSC Duncan, START and the ERRS Removal Manger attended a community meeting in Kilauea to discuss the planned removal activities. The meeting was also attended by the Deputy Director of HDOH and several other HDOH Representatives.
August 3, 2012; Friday
Weather: Sunny skies throughout day with very mild rain events. Low 80’s and humid.
Personnel on Site: 1 EPA OSC, 4 ERRS Contractors, 2 START Contractors
On-Site Activities: The ERRS contractor continued preparing residential yards for excavation activities to begin next Monday. Debris was stockpiled near Aalona Street in the front yard of home site 4277. The ERRS contractor subcontracted a septic service and had the cesspool on home site 4277 pumped out. The septic service contractor recommended that the cesspool be treated with an acid solution to remove residuals. This recommendation was conveyed to the property owner. The ERRS contractor also arranged for a pest control company to spray around the structure at home site 4277 to prevent bugs from migrating into the house when they are disturbed by the excavation activities. The Kauai Island Utility Cooperative arrived on the site in the afternoon and relocated the power pole in the rear yard of home site 4275. The old pole will be removed after the telephone and cable companies move their wires to the new pole. They are both scheduled to come out on Monday morning. START set out monitors and samplers and collected interior and exterior base line readings. OSC Duncan and START Tiballi provided safety training to county employees who work at the landfill.
August 4, 2012; Saturday
Weather: Sunny skies throughout day, wind blowing toward the southwest. Mid- High 80’s and humid
Personnel on Site: 1 EPA OSC, 4 ERRS Contractors, 2 START Contractors
On-Site Activities: The ERRS contractor began removing tree stumps on the residential properties and excavating soil. The ERRS contractor used a fire hose to suppress dust during these activities and START collected air monitoring and sampling data. Excavated soils were covered with plastic at the end of the day to prevent windblown migration over the weekend. START completed the consolidated site safety plan and the site workplan. On Saturday afternoon OSC Duncan received a request from the Kauai County engineer to install dust screens around the site. The county stated that dust screens are a best management practice (BMP) they require. After trying to convince the county that the steps currently being employed at the Site were far more adequate than dust screening, OSC Duncan agreed to install a dust screen. The ERRS contractor will attempt to hire a local fencing contractor first thing Monday morning and have them install the screen.
