Th e mine is about 5,000 feet above sea level, Tailings Remediation and in the Rogue River-Siskiyou National Forest’s Siskiyou Mountains Site Restoration Ranger District. Rogue River, Oregon Th e hard-rock mine was named for the characteristic blue sheen of weathered chalcopyrite, the copper ore that miners took out of the Joe Creek drainage. Th e tailings are from the estimated 12,000 feet of adits SUMMARY and shafts miners dug into the mountain early in the 20th century. ERRG was tasked to restore the site where waste rock from the mine has been leaching toxic material into surface waters for over 100 years. Owner Sulfuric acid, arsenic, lead, U.S. Forest Service cadmium, copper and zinc have been leaching into the Location Applegate River watershed, Rogue River-Siskiyou National Forest, Oregon impacting water quality in Joe Creek and the lower Elliott Award Date Creek watershed in violation of July 2010 the federal Clean Water Act. Th e project includes removing Actual or Completion Date 66,500 cy of toxic waste or Projected Completion Date material on the site, reclaiming July 2013 the site, installing erosion Award Amount control, and pH treatment structures, replacing topsoil and restoring $10.9 million native vegetation by growing 10,000 native plants. Access, terrain and logistics make this a challenging and complex Final Contract Price project. ERRG trucks navigated the roughly 1,000 vertical feet of the $14.9 million site on up to 35% haul roads to carve a huge bowl out of the earth and create a lined and capped repository for the toxic tailings. ERRG Services Provided HazMat Remediation fabricated and installed 10 adit gates and closed 1 adit and a vertical Road Construction shaft with polyurethane foam techniques (PUF).

Th e work included repainting the 1,468 square foot Station Guard Station and shed. Prior to stabilization activities, a visual survey was performed, inspecting all exterior painted surfaces to identify areas of deteriorated paint. SUMMARY Removal of chipping and fl aking paint was performed manually using paint scrapers. All scraped surfaces were kept wet to reduce emissions of LBP, and the surfaces were wiped down following the paint scrape. Owner All visible LBP debris were collected and rolled up in sheeting. During U.S. Forest Service this project, approximately 170 pounds of LBP debris was collected. Th e debris was sealed in a Location heavy-duty bag, and disposed of off -site. Gifford Pinchot National Forest, Washington Following the paint scrape and cleanup, all newly scraped bare wood external surfaces of Award Date both structures were coated with an oil-based, January 2010 non-lead-containing primer.

Soil samples were collected along the adjacent drip line for soil evaluation. Samples Services Provided were collected from eight locations around the Guard Station, and Soil Removal and Disposal from four locations around the wood shed. Based on the soil analytical results, lead contamination in soil was identifi ed at the Guard Station. As a result, remediation of soil was required. Th e public frequently uses the front and back areas of the Guard Station building, thus a high potential existed for the public to come into contact with lead-contaminated soil. ERRG recommended soil remediation including excavation and backfi ll, at the contaminated locations. ERRG conducted the remediation of lead-contaminated soil identifi ed in the front and back of the Guard Station. ERRG excavated 12 tons of lead contaminated soil from the Guard Station Building around sidewalks, porches and existing trees, disposing of the lead contaminated soil at the Hillsboro Landfi ll. ERRG replaced the excavated soil with native soil, returning the site to pre-remediation condition.

USCG Seattle Massachusetts Avuenue ERRG was contracted by the U.S. Coast Guard (USCG) to conduct Phase I and Phase II Environmental Due Diligence Audit (EDDA) to Phase I and II EDDA support the future transfer of Massachusetts Avenue Right-of-Way from the City of Seattle to the USCG. Th e site is situated in an industrially zoned urban area, on a highly SUMMARY developed waterway, and surrounded on three sides by industrial properties with similar topographical relief. USGS historical topographic maps indicate the site has existed as a right-of-way providing street vehicular and railway access to the facilities located at Owner adjacent Piers 34, 35, and 36, since the early 1900s. Th e site is paved U.S. Coast Guard and provides vehicular and foot access to the Base Seattle facility located on Piers 36 and 37. No structures are present on the site, although a Location series of concrete jersey barriers has been arranged to direct traffi c across Seattle, Washington the property. During the Phase I EDDA no immediate environmental concerns were Award Date observed, although a single monitoring well was noted on the property. September 2009 It was recommended that a Phase II EDDA be performed. Actual Completion Date Th e Phase II EDDA included collection of soil and groundwater samples from soil borings advanced at fi ve locations spaced regularly along the Ongoing length of the site, adjacent to sanitary sewer lines and an abandoned rail line that traverse the length of the property. Upon completion of all Award Amount sampling activities, the boring locations were abandoned in place and $49,055 fi lled with bentonite pellets. Surface completion consisted of an asphalt- concrete patch to match the surrounding surface. Final Contract Price $49,055 All soil samples were analyzed for volatile organic compounds (VOCs); semi-volatile organic compounds (SVOCs); gasoline-, diesel-, and Services Provided residual-range organics; and target analyte list (TAL) metals. ERRG Phase I and II EDDA collected two soil samples from each of fi ve soil boring locations, for a total of 10 samples. Soil samples were collected using direct-push drilling and sampling equipment. Once groundwater was reached during advancement of the soil borings, a grab groundwater sample was collected from each of the fi ve borings using a low-fl ow peristaltic pump and disposable tubing. Two gallons of groundwater were purged from the boring prior to collecting each sample. Because the groundwater samples were collected from borehole casings instead of dedicated monitoring wells, analytical data for the groundwater samples were considered qualitative and were used for preliminary evaluation only. All Total Petroleum Hydrocarbons (TPH), VOCs, SVOCs, and TAL Metals detected in the soil were below the cleanup level. Arsenic, chromium, and lead were detected in the groundwater at concentrations exceeding their respective cleanup levels.
