RAMCO occupied a building located within the Dallesport Industrial Park, where it extracted aluminum from dross it received from primary aluminum smelters.  Dross is a by-product from the primary smelting process, and the major constituents of dross are aluminum, aluminum oxides, mixtures of nitrides, mixtures of chlorides, and traces of other impurities.

The disposal site is located in the Dallesport Industrial Park, which is owned and operated by the Port of Klickitat.  The industrial park is a mixed light and heavy industrial facility, and is approximately two miles east of the small community of Dallesport, Washington.  The 2007 population of Dallesport is 1,239.

The contaminants of concern (cyanide, polycyclic aromatic hydrocarbons [PAHs], ammonia, and metals including aluminum, cobalt, copper, iron, manganese, and vanadium) are potential hazardous substances or pollutants or contaminants as defined by sections 101(14) and 101(33) of the Comprehensive Environmental Response, Compensation, and Liability Act, as amended, 42 U.S.C. section 9601(14) and (33).

7/29/10  Thursday

• EQM loaded and Dietrich Trucking transported 4 truck loads of material to the Wasco Landfill.  This completed the removal of the existing stock pile of material near the entrance of the site. The total tonnage removed from the site for the day  to Wasco County Landfill was 128.27.
• EQM continued to remove the top soil from the northeast rim of the pit down to the contaminated layer.  Water spray was used to control dust. 
• START monitored downwind for particulates. 
• EQM started to excavate the contaminate layer under the northeast rim into the stockpile of material in the pit. EQM completed removing contaminate from Northeast rim, except around monitoring well #3.
• EQM started to move stock piles #2 and #3 closer to the entrance. While doing so, crushed up large material and check each stock pile for any K088 listed waste. The moving of the material allowed for additional off gassing of any remaining ammonia odor. Maximum ammonia readings during this period were 7 ppm, but not for long enough duration to produce any time weighted averages (TWA), as measured by portable instrumentation.
• START monitor continuously for particulates and ammonia. START moved the monitors to keep them down wind from the work area. All constitutes being monitored were below action levels.
• EPA/OSC Rodin and EQM/PM Ficek discussed final clean up criteria as well as EPA's expectations for the final appearance of the removal.

• EQM cleaned up small areas of contaminate around and approximately 25 feet below the surface of monitoring well #3.
• After the removal around and below monitoring well #3 was completed, EQM backfilled around the island of remaining soil to stabilize the well casing and steel protective pipes.
• As a final clean up on the Southeast floor of the removal site, EQM excavated small areas of contaminate in an effort to remove as much contaminated soil down to uncontaminated soil.
• START used ammonia monitoring instrumentation to assist in delineating areas of contaminated soil, along with visual signs.
• EQM continued to move stock piles #2 and #3 from the Southeast portion of the removal site towards the site entrance. Aeration and the crushing of large clumps of material were also accomplished during this operation.
• Through out the day, water spray from the tanker truck was used to control dust on roadways. A hand held hose was used to control dust during the back-fill, excavating contaminated soil, and moving and aerating the stockpiles.
• At the beginning of the work day, START placed particulate (Data Ram 4) and ammonia monitors (AreaRAE and ToxiRAE II) down wind of the site on monitoring well #2. All constitutes being monitored were below action levels.
• Radial stacker (conveyor) arrived on site.  Will be set up early next week for continued processing of waste.

• One EQM 330 Cat track hoe continued to aerate and move material from stockpile #3 to stockpile #2. This operation also visually checked the material for any foreign materials and crushed large pieces.
• A second EQM 345 Cat track hoe and the D8 Cat worked up on the Southeast rim of the removal site, pulling the clean soil that was removed on July 28, 2010, pushing it back into the area excavated to remove the contaminated soil.
• The water tanker truck was used heavily around all drivable areas on site to control dust. Winds were at 17-20 mph out of the West with forecasted gusts up to 30 mph. A 1.5-inch hand held hose was used in the immediate area around the blade of the D8 and the bucket of the 345 Cat for dust control.
• START and USCG deployed the Weatherpak (MTR) with remote monitoring, one AreaRAE with remote monitoring, an ammonia ToxiRAE II, and one Data Ram 4. All monitoring instrumentation was placed down wind at monitoring well #3.

Weather information and forecast is reviewed each morning by START.

All personnel are wearing reflective vests, hardhats, steel toe boots, and have radio communication when down in the removal area.  The ground crew member handling the water hose has sealing goggles and started wearing dust masks during windy days.

Air monitoring for particulates and ammonia continues.  No detection levels have been above established action levels.
