1.1.1 Incident Category
Time-Critical Removal
1.1.2 Site Description
The Site is characterized as a time-critical removal. The Site includes land that was used formerly for the commercial growing and harvesting of fruit from orchard trees and are currently zoned for residential or public use primarily in North Whitehall Township, PA. Lead arsenate pesticide was historically used for several decades at the Site until its use was banned in 1988 by EPA. Elevated levels of arsenic and lead have been detected in surface soil samples on residential parcels and in public use areas. The FMO Pesticide Action Memo was submitted by the OSC and signed on September 1, 2010 approving a Removal Action which addresses contamination at residential parcels.
1.1.2.1 Location
The site is located in the Orefield/Schnecksville area of North Whitehall Township, Lehigh County, Pennsylvania
1.1.2.2 Description of Threat
Incidental ingestion of lead and arsenic through direct contact with contaminated soil, or ingestion of contaminants from small particles that have been aerosolized from the disturbance of soil.

2.1.1 Narrative
2.1.2 Response Actions to Date
Currently a total of 22 properties require removal activities. Eighteen properties have been completed to date. "Complete" refers to excavation being complete and the yard being restored with sod. Additional watering activities are conducted at a given property after being completed.
Beginning October 21, ERRS continued excavation at the 20th property. Certain areas of the back yard around the resident's pool and driveway need to be hand dug. Excavation is required in portions of the back and front yards at this property. Backfilling in the back yeard was completed in stages to increase the likelyhood of restoring the yard with sod before the weather gets too cold. Samples were be collected prior to backfilling. No significantly elevated dust concentrations were identified downwind of or within the work area during this time period. All excavation areas were covered with impermeable plastic prior to weekend cessation. In addition to excavation activities, sod was installed at the 19th property, on October 26.
Preliminary data from the property at which Phase II samples were collected last week indicate elevated levels of arsenic in the front, side, and back yards. The property will likely be included for removal, pending validated data and access from the resident. Validated data is due next week.
ERRS continues to water newly installed sod at properties identified by EPA. Sod was not watered if it rained.
A total of 117 rolloffs containing an estimated 1,872 tons of soil have been shipped offsite for disposal as non-hazardous waste. There are currently 5 rolloffs staged onsite, two containing soil and three empty. Two of the empties are for soil and one is for debris.

2.2.1 Anticipated Activities
Property specific work plans for residences requiring soil excavation will continue to be prepared. EPA will be meeting and scheduling with residents where removal activities may take place. At times scheduled between the resident and EPA, excavation of properties will occur, samples will be collected, backfill installed, and sod installed. Currently excavation activities are planned to begin at the 22nd property the week of November 7th. At this property, only the Toddler Play area requires removal action and this area will be restored with mulch. Pending receipt of validated data and access, the 23rd property will be added to the schedule.
Samples will be shipped to an offsite laboratory for Post-Excavation activities. These samples will be shipped for offsite analysis. ERRS will continue to water sod as properties indicated by EPA.
EPA will prepare closeout letters for those properties where we have received validated data for post-excavation sampling. Letters will include maps showing where EPA excavated and restored the property and a table of post excavation sampling results. Post-excavation walk-throughs are being scheduled at residences at which excavation activities have been completed.
2.2.1.2 Next Steps
2.2.2 Issues
Weather continues to hamper operations somewhat. However, ERRS contractor has been able to stay close to our projected schedule for excavating and backfilling.
