PROjECT NAME & LOCATION: KORITA REPACK - Nogales, AZ

Nature of SHC’s Responsibility:SHC responded to an emergency response request from Korita Repack in Nogales, AZ to clean up a diesel fuel spill on asphalt and concrete. The spill covered a large area and was discovered to have penetrated the asphalt and concrete to the soil below. SHC excavated and disposed of 402 tons of petroleum contaminated soil, asphalt, and concrete. Once all of the contaminated soil was gone, SHC collected confirmation samples and backfilled the excavation.

Total Cost of the Project: $91,703.95(T&M Contract)Completion Date: May 2009

PROjECT NAME & LOCATION: NU ChROME - Tucson, AZ

Nature of SHC’s Responsibility:SHC was originally contracted to perform site characterization of former chrome electroplating facility that was under enforcement action from the EPA at the time. After soil sampling results confirmed the existence and chrome and lead contamination up to a depth of 8 feet in the soil, SHC bid and was awarded the remediation work that was required. After developing an EPA approved Site Assessment Plan and Site Cleanup Plan, SHC successfully excavated and disposed of approximately 400 tons of chrome and lead contaminated soil classifying as hazardous waste. Once removed SHC backfilled and compacted the excavation.

Total Cost of the Project: $171,573.51(Fixed & Unit Rate Contract)Completion Date: October 2009

PROjECT NAME & LOCATION: ADOA I-19, INTERSTATE 19 KILOMETER POST 16.5 MEDIAN

Nature of SHC’s Responsibility:At the request of the Arizona Department of Transportation, SHC responded to a tanker truck accident on I-19. The tanker truck was hauling up to 7800-gallons of gasoline and diesel fuel. The accident resulted in the release of several hundred gallons of fuel onto the soil in the median, some of which also passed into a stormwater drainage canal. The spill was of particular concern due to the proximity of the Santa Cruz River and the fact that the groundwater levels in the area ranged between 15 and 60 feet below ground surface. SHC set up the necessary traffic control, installed stormwater controls, obtained clearance from Blue Stake, and obtained the necessary permits to complete the remediation. Petroleum contaminated soil (pcs) was removed from the stormwater drainage canal and the median and was loaded into end dump trucks to be hauled off to the Cactus Landfill for disposal. Approximately 3,069 tons of pcs was hauled offsite and disposed of. SHC completed confirmation sampling throughout the remediation project to ensure that contaminant levels were below the applicable Arizona Residential Soil Remediation Levels and Groundwater Protection Levels. Following confirmation that the remediation was complete, SHC backfilled the excavation and returned the site to pre-spill conditions.

Total Cost of the Project: $331,972.09(T&M Contract)Completion Date: July 2010 (Project Duration: 2 months)

PROjECT NAME & LOCATION: SUNDT hISTORIC LANDFILL REMEDIATION - Tucson, AZ

Nature of SHC’s Responsibility:SHC was contracted to remediate a historic landfill that had been in operation during the 1960’s and 1970’s. Scrapers, front loaders, bull dozers, an excavator, a blade, dump trucks, a water pull, and a water truck were some of the equipment used to remediate the landfill that was located on a site that encompassed an area less than 10 acres. SHC was responsible for removing and stockpiling the overburden soil covering the top of the landfill, constructing engineered benched side walls and entrance ramps, and removing and disposing of all of the landfill waste. SHC’s responsibilities also included environmental overview of the project to include Air Quality Permit and SWPPP implementation, dust control, odor control, and environmental sample collection and analysis. This remediation project was completed in approximately 3-months from initial site preparation to collection of over 125 confirmation soil samples. At the completion of the project, over 35,000 cubic yards of overburden soil had been removed and stockpiled and over 31,500 cubic yards of landfill waste was removed and disposed of. This included over 47,600 tons of municipal solid waste hauled offsite in over 2300 truckloads, disposal of approximately 100 cubic yards of tires, 800 tons of concrete, and 32 tons of hazardous waste. At the successful completion of the project, SHC secured for the client a “No Further Action” determination from the Arizona Department of Environmental Quality Voluntary Remediation Program for the soils remediation on the site.

Total Cost of the Project: $1,743,224.00(Fixed & Unit Rate Contract)Completion Date: March 2011

PROjECT NAME & LOCATION: FREEPORT TANKS - Near Silver City, NM

Nature of SHC’s Responsibility:Removal of product and cleanout of over 100, fuel, oil, and corrosive material storage tanks at the Freeport McMoRan Cobre Operations Mine and Tyrone Operations Mines in New Mexico. Several of these tanks required confined space entries to complete the scope of work.

PROjECT NAME & LOCATION: TEP bUNKER OIL TANK - Tucson, AZ

Nature of SHC’s Responsibility:SHC won a contract to clean out a 10,000,000 gallon bunker oil tank at the Tucson Electric Power Plant in preparation for demolition. After cutting an 8x8 foot doorway through the 1 3/8” thick steel sidewalls, SHC began the process of cleaning the tank. This opening allowed us to drive a man lift into the tank so personnel could power wash the 48 foot walls. Due to the extreme temperatures of August in Tucson, the work was completed at night. This physically demanding, confined space operation took SHC 19 working days to complete.

PROjECT NAME & LOCATION: MT. GRAhAM - Mt. Graham Observatory, AZ

Nature of SHC’s Responsibility:At the request of the University of Arizona, SHC responded to a large diesel spill from an above ground storage tank at the Mount Graham Observatory. After working with University of Arizona personnel to work out a plan of action, SHC personnel mobilized to the Observatory on two occasions to provide bioremediation services to areas around the observatory where soil excavation was not feasible. SHC collected and analyzed initial samples and final samples of the bioremediation areas to confirm that bioremediation efforts were successful. SHC also collected and analyzed confirmation soil samples from the excavation areas. The University of Arizona excavated the pcs from other areas around the Observatory and transported the wastes to the base station at the base of the mountain. SHC provided transportation of the wastes from that point to the Los Reales landfill in Tucson, AZ. A total of 1,515 tons of pcs was removed and disposed of as a result of the spill. SHC also provided transportation of clean backfill back to the base station to be used by Universitypersonnel for backfilling.

PROjECT NAME & LOCATION: DM ShOOTING RANGE – Davis Monthan Air Force base

Nature of SHC’s Responsibility:SHC was contracted to alter the design of an existing small arms shooting range contaminated with lead at the Air Force Base in Tucson, AZ. SHC using a bull dozer, excavator, and loader moved a berm meant to trap lead shot to extend out the length of the range. Once the berm was moved, SHC had to install new drainage culverts and ensure that pooling of rainwater would not occur crating a ricochet hazard.
