After the West Site entrance and staging pad construction was completed in December 2008, the Site contractor began work on enhancing erosion control structures on both the West and East Sites. The Site contractor is completing a round of cleanup verification sampling (CVS). CVS generates data that is then analyzed and used to identify areas of the Site where Remediation Goals have not been met and, therefore, where additional excavation is needed. The Site contractor and the National Park Service have been reviewing the CVS data as it is generated, and while all data is not yet in, at this time it appears that a significant area of the Site will require additional excavation. For this reason, the Site contractor has developed a plan to initiate additional soil excavation on August 17, 2009. The excavation will begin on the portion of the East Site to the north of Hines Hill Road, then move to the portion of the East Site south of Hines Hill Road. The Site contractor and the National Park Service are making every effort to limit interference with the traffic flow on Hines Hill Road during the excavation, loading, and transportation of material to and from the Site. As the excavation of the East Site continues, another round of CVS will follow. Excavation and further sampling will continue until Remediation Goals have been met. It is anticipated that excavation of the West Site will begin in October 2009, and be completed by the end of the calendar year or soon thereafter. Grading, revegetation, and final road repairs will follow, but such activities cannot begin until all excavation has been completed.

During the winter and spring months, contractors at the Krejci Dump Site have been removing accumulated sediment from the catch basins and performing maintenance activities on the other erosion control structures, such as replacing hay bales and silt fencing and placing seed for temporary vegetation cover. Over the course of the last 12 months, soil samples have been collected and analyzed to determine whether or not the Site Remediation Goals (RGs, or cleanup levels) have been met. Although contaminant concentrations were significantly reduced by the first round of soil and debris removal, a significant portion of the Site continues to exceed the cleanup levels. Consequently, preparations are underway for additional soil removal from both the East and West Sites. A staging pad was built on the West Site in December 2008, and East Site staging pads will be installed this summer. Trees have been selectively removed recently from some of the areas that will be subject to the upcoming soil excavation. It is anticipated that additional soil removal will begin in August 2009 and continue for 2 to 3 months. Soil sampling will be performed as areas are excavated to determine the need for further excavation to meet cleanup levels. The same safety measures and traffic patterns will be used during these activities as were used during the 2005 to 2007 soil removal. Site regrading and revegetation can begin once site cleanup levels have been attained and no further soil removal is necessary, which NPS projects will be sometime in 2010.

Upcoming site activities include tree cutting in some areas to facilitate excavation and the removal of accumulated sediments from the sediment control structures within the site. Sediment removal had been delayed by the weather and site conditions. These activities are expected to occur over the next few weeks. Verification sampling tests are still being evaluated to determine whether remediation goals have been met across the site. After these tests are complete, the extent of further excavation at the site will be known.

On November 10, 2008, Ford's contractor, EQIS, began resampling certain grids where last summer's results indicated contaminant concentrations close to the Remediation Goal established for the Krejci Dump Site. Resampling activities will require less than a week of field work, followed by six to eight weeks of laboratory analysis and data interpretation. In addition, EQIS is implementing site maintenance activities on erosion control structures, including repair or replacement of silt fences and hay bales within the East and West Sites. These activities will continue as needed for the duration of the project. The week of November 17, EQIS began the reconstruction of the West Site entrance along Hines Hill Road. This activity will involve the removal of fewer than 10 truckloads of soil and debris, followed by delivery of clean gravel and other materials needed to rebuild the entrance. The northbound lane of Hines Hill Road will be closed for one or two days and the contractor will provide flaggers to ensure traffic safety at these times. Following the reconstruction of the entryway, EQIS will build a new staging area within the Site adjacent to the entrance. This staging area will be use, among other things, to support a vacuum system that will be used for the removal of accumulated sediments from the sediment control structures within the site. Staging area construction is expected to take approximately two weeks, followed by one to two weeks of sediment removal.

During the week of November 10th, contractors at the Krejci Dump Site will be working to re-establish a staging area on the West Site. This activity will require traffic control on Hines Hill Road during construction. In the following weeks, maintenance activities to remove accumulated sediment from sediment basins and check dams will be undertaken. A small amount of truck traffic is expected. Verification sampling results (which will indicate the extent of any further excavation activities) are still forthcoming.

With the exceptions identified below, there will be an anticipated lull in site activity for the months of August and September while the contractor analyzes data generated from soil sampling conducted in the past few months. Small flags observed at the site were part of this sampling effort. If the sampling results are considered valid, it will be determined whether remediation goals have been met and where additional site excavation is needed. Two exceptions to this lull are activities associated with rebuilding the West Site entryway and maintenance of the sedimentation basins. Plans are being made for the West Site entrance on Hines Hill Road to be stabilized and reconstructed to facilitate removal of sediment from erosion control structures, as well as possible future excavation in areas where remediation goals have not been met. The entrance reconstruction may require the removal of fewer than 10 truckloads of soil and debris, and if so, the northbound lane of Hines Hill Road will be closed for one day during this construction activity, and the contractor will provide flaggers to ensure traffic safety. It is anticipated that excavation will resume in October, but at this time it is not possible to predict how extensive this excavation effort will be. Excavation and further sampling will continue until remediation goals have been met. Grading, revegetation, and final road repairs will follow, but such activities cannot begin until all excavation has been completed.

The contractors remobilized this spring to conduct Cleanup Verification Sampling. The sampling was finally completed in June. Testing to see whether we have met remediation goals for contaminants across the site is underway.
February 21, 2008 -
Contractors will be drilling a groundwater monitoring well to replace one that was damaged during the excavation. Winter site monitoring continues with assessments of storm water control structures during significant rain events or snow melt. Full remobilization for testing of soils and possible additional excavation will not likely occur until late spring.
