2.1.2 Response Actions to Date

Week of October 14 - October 20, 2013:

ERRS continued subgrade work, laying down of marking barrier, spreading and compacting of clay on the south side of the Site. A total of approximately 22,886 tons of clay and 1,983 tons of stone have been received to date.  Due to rain, wet and humid conditions, dust monitoring was not conducted and work activities were limited.  No visible dust emissions were observed. To date, the wind/solar power generator has operated for approximately 507 hours saving approximately 660 gallons of diesel fuel.

• Completed the installation of drainage pipe beneath road along east side of the Site;
• Completed raising 2 sanitary sewer manholes to match new grade;
• Repairs were made to cap in the northeast portion of the Site as a result of the water main break;
• Collected sample from soil borrow for topsoil.

Week of October 21 - October 27, 2013:

ERRS continued subgrade work, laying down of marking barrier, spreading and compacting of clay on the south side of the Site. A total of approximately 27,808 tons of clay and 2,041 tons of stone have been received to date. Hauled 40 cubic yards of wood and vegetative debris to Athens/Hocking Reclamation Center for a total 360 cubic yards. START continued real-time air monitoring and air sampling activities around construction areas. All air samples and air monitoring daily averages to date have been below the 57 ug/m3 action level. Field activities were limited due to rain.  To date, the wind/solar power generator has operated for approximately 604 hours saving approximately 795 gallons of diesel fuel. 

• Began spreading topsoil on and along the fenceline of the northeastern lot of the Site; 
• Decontaminated off road dump truck for demobilization;
• Decontaminated both track hoes, one for demobilization and the other for use in clean areas;
• Scraped and replaced gravel along road leading to baseball fields;
• Top soil sample results indicated the borrow was useable.

Week of October 28 - November 3, 2013:

ERRS completed subgrade work, laying down of marking barrier, spreading and compacting of clay at the Site. A total of approximately 28,543 tons of clay, 2,147 tons of stone and 858 tons of topsoil have been received to date. START completed real-time air monitoring and air sampling activities around construction areas. All air samples and air monitoring daily averages to date have been below the 57 ug/m3 action level. Field activities were limited due to rain. To date, the wind/solar power generator has operated for approximately 703 hours saving approximately 930 gallons of diesel fuel.  

• Topsoil was added to northeast lot and graded; however due to weather conditions and the moisture content the topsoil could not be properly graded and has discontinued;
• Lined drainage areas and pipe outfalls' with gabion stone; 
• Areas outside the Site fence were secured for the season with temporary fencing and jersey barriers to prevent foot and vehicle traffic;
• Erosion controls were installed along site drainage pathways;
• Began decontaminated remaining equipment for demobilization. 

Week of November 4 - November 10, 2013:

ERRS completed securing the Site for demobilization for the year.  Roads were washed and stone added to areas as needed.  Erosion controls were inspected and secured as needed.  All remaining equipment was decontaminated.  A total of approximately 28,543 tons of clay, 2,147 tons of stone and 858 tons of topsoil have been received to date. A total of 360 cubic yards of wood and vegetative debris was transported to Athens/Hocking Reclamation Center.  The wind/solar power generator has operated for approximately 779 hours saving approximately 1,036 gallons of diesel fuel.

2.1.3 Enforcement Activities, Identity of Potentially Responsible Parties (PRPs)

EPA is still in the process of locating and determining viable potentially responsible parties.
 

• Complete the installation of the cap by spreading and grading topsoil;
• Re-vegetate the Site and plant trees to stabilize sloped areas and prevent erosion of cap;
• Make adjustements to drainage as neccessary.
