Progress on BNSF property

Powerhouse stack was removed with clam shell crane on 8/31/04 by contractors with BNSF.  The stack was weak and in very poor condition.  Removal was done in 2 hours.  Water was sprayed to keep dust down.

The inside portion of three of the stack bricks were checked with the XRF.  Lead concentration was 93, <37, and 83 ppm.  Arsenic was 328, 89 and 196 ppm.  Mercury was <26, <27, and <25 ppm.

Other activities

Ambient air monitoring by Coast Guard show all readings below action levels.

Next Steps
Continue to shape and work on the smelter and backfill all excavations with 3/4 rock and level.

EPA will continue meeting with homeowners to obtain access agreements and conduct walkthroughs.  EPA lacks access agreements from two homeowner one who is out of town and another who needs to remove junk material off his propety.

Continue excavation at two empty lots on Leroy and between 9th and 10th streets.

An Avista Utility representative from Spokane approached EPA with two properties they held ownership in town.  They were unaware of the lead assessment and cleanup work and asked if EPA would sample soil on their property.

BNSF will move bricks to consolidation area starting September 7th.

Work will stop after September 1 for the holiday weekend and start back up on September 7.
