Big Horn 5-6


Soli-Bond, Inc. was contracted by Burlington Resources located in Wyoming to remediate 4,206 cubic yards of inverted mud drill cuttings that were diesel saturated and impounded in a large reserve pit.

Treatability bench testing was completed and a specific reagent recipe was developed for this project.  The waste was then stabilized using the patented Soli-Bond process. The pit was actually stabilized in 17 separate sections, ensuring quality control throughout the duration of the project.

Following treatment of each separate cell, one (1) ft. of clean soil was applied. Following the completion of 17 cells in this manner, the entire area was backfilled with four (4) ft. of clean cover and groomed.

Kirgis, Isabel, Howell-Snyder & Arnott Sessions Tank Batteries


This project located in the Byron-Garland area of Wyoming was unique in that it consisted of 13,868 yards of materials in four (4) separate NPDES pits.

The impounded materials contained river rock, oily sludge and contaminated sand. The levels of the pits were initially too high to be backfilled to natural grade. Therefore all rock 1” plus was screened and cleaned, then placed in low areas at landowner’s discretion in a manner that created more usable farmland.

The remaining sludges and contaminated sands were stabilized and covered with clean soil as per W.O.G.C.C. Rules and Regulations.

Griffen Jones Battery Pit No.1-4


Soli-Bond, Inc. was hired to excavate and stabilize four (4) buried production pits initially containing a total of 2,459 ydsł of oily sludge in the Byron-Garland area of Wyoming.  Soli-Bond, Inc. initially removed the clean cover soil off of each pit area and then carefully delineated the boundaries of each individual pit.

Subsequently, the sludge and tar was stabilized/solidified using the patented Soli-Bond process.

Finally, the surface areas of each pit were covered with clean soil and groomed.

Stabilization and Closure of Coal Tar Sludge Impoundment

Pittsburgh, PA

Soli-Bond, Inc. (SBI) was successful in developing and demonstrating a unique process technology to stabilize coal tar by-product sludges at a coke-making facility located near Pittsburgh, PA prior to the placement of an earthen/geotextile capping system.

Following an on-site demonstration utilizing process technology and reagents developed by SBI laboratories, the contract was awarded to SBI for stabilization of approximately 92,000 ydsł of impounded sludges.

Sludge consistency varied widely throughout the impoundment, being comprised of coal tar decanter sludges, tank bottoms, distillate column bottoms, and off-spec coal tars from the coke making and coal chemical refining operations.

SBI successfully stabilized the impounded wastes to unconfined compressive strengths greatly exceeding client specifications throughout the deep (40 ft.) lagoon.

Following stabilization, a geotextile and earthen cap was successfully constructed on impoundment surface as a final step of the in-situ closure plan.

Golden Eagle Refinery

Carson, California

Approximately 1,000 tons of soil exceeding California Soluble Lead Threshold Concentration (SLTC) was stockpiled on-site. The soil was excavated from the surface to three feet below grade of a former landform area on the site.

The approved Remedial Action Plan (RAP) recommended on-site treatment using chemical stabilization followed by off-site disposal of the lead fixated soil at a licensed Class III landfill.

Soli-Bond, Inc. was retained by the client to remediate the lead-impacted soil and to find an acceptable disposal location. Soli-Bond, Inc. developed the stabilizing reagent through bench scale testing and directed its application. The remediation work included screening, stabilization, and treatment verification. Confirmation sampling was conducted for every 50 tons processed. All material processed passed verification.

Soli-Bond, Inc. contacted an acceptable landfill and obtained regulatory approval to use the processed material as alternative daily cover at a Class III landfill.

Oil & Gas Production Pit Closures

Bridgeport, Illinois

Soli-Bond, Inc. was contracted for oil & gas production pit closures in Bridgeport, Illinois.

Solidification of approximately 150 oil & gas production facility pits containing production and drilling wastes with varying amounts of hydrocarbons, barium compounds, and trace amounts of heavy metals. Total amount of sludge treated over a two-year period was approximately 180,000 ydsł.

These pits were located in row crop areas and in most cases required backfilling to level grade in order to support cash crop production. The client had experienced past failures in accomplishing reliable results by utilizing inferior solidification techniques and materials.

Past failures included sinking areas over backfilled pits and quagmires created by the stabilized sludges reverting back to their original state. To date all 150 sites processed using the Soli-Bond system have proven to be predictably stable with many supporting normal row crop and land use conditions.

Oil & Gas Well Reserve Pit – Oil Base Mud

Evanston, Wyoming

In-situ Chemical Fixation and Solidification of approximately 26,000 ydsł of oil base mud (27% oil and grease average 30,000ppm chloride average).

The end product yielded a leachate of less than 10,00ppm oil and grease, less than 5,000ppm chlorides, and an unconfined compressive strength greater than 2,500 lbs. psf.

Waste Sludge Pond Closure

Pascagoula, Mississippi

Stabilized and solidified 7,000 ydsł of hazardous wastes associated with production of anilines. Wastes contained various amounts of DINITRO, PHENOL, DINITRO PARA CRESOL, DIINTRO ORTHO CRESOL, AND 2,4,6 TRINITRO PHENOL (picric acid).

Regulatory agency was Pollution Control Department, State of Mississippi.

GM Delphi Interior & Lighting – Tar Sludges

Trenton, New Jersey

In 1996 Soli-Bond, Inc. was contracted by Laidlaw Environmental Services to assist them in resolving a failing remediation project. The project consisted of removal, dewatering, and conditioning of approximately 7,000 ydsł of tarry F006 sludge.

A contractor had been on-site for approximately 6 months. During this time period they had processed only 150 ydsł of sludge. Soli-Bond, Inc. accepted the job with only 60 days remaining to complete the project before a shutdown deadline. Soli-Bond, Inc. mobilized equipment and immediately started to remove and process tar sludges from the wastewater treatment batch tanks and primary settling tanks. Even though the sludge was heterogeneous both physically and chemically, the multi-step treatment process implemented proved to be extremely effective in the field.

The project was completed on schedule with all sludges being processed to landfill acceptable condition, weighed, and loaded into standard railroad gondolas for transport to Laidlaw’s Oklahoma facility.

Lead and Copper Contaminated Soil

Beaumont, California

In 1994, a manufacturer of computer circuit boards was slated for disassembling and eventual sale. During the assessment of the property, soil samples indicated extremely high levels of lead and copper, which were characterized as hazardous under the Resource Conservation and Recovery Act (RCRA).

Approximately 5,000 tons were excavated and stockpiled for treatment. Further investigation uncovered an aged municipal solid waste burn dump, circa 1940. Characterization revealed elevated levels of lead, which were determined to be RCRA hazardous. Approximately 3,000 tons of ash were excavated and stockpiled for treatment.

Soli-Bond, Inc. was contracted for remediation services. A thorough chemical stabilization treatability study was performed to evaluate the reagent type, recipe and effectiveness on the contaminants present.

Following a successfully verified treatability study, Soli-Bond, Inc. mobilized its Transportable Treatment Unit (TTU), permitted through the State of California, Department of Toxic Substance Control (DTSC).

Remedial actions included screening of all material prior to chemical stabilization processing and stockpiling for positive process verification.

Upon successful verification analysis, the processed material was loaded into railroad cars and transported off-site for disposal as a non-RCRA waste. All 8,000 tons of soil was processed over a 7-day period.

Ultramar Refinery

Long Beach, California

Soil excavation was conducted in conjunction with construction of a Clean Fuels Project (CFP).

CFP is a State and Federal mandated program to produce reformulated gasoline at the refinery.

Aerial photographs of the excavation site indicated a long history of use as a commercial/industrial facility and the site of oil exploration and production.

The lead-impacted soil was encountered in the upper six inches of soil. The lead-impacted soil was excavated, sampled and stockpiled on-site.

Soli-Bond, Inc. was contracted to develop a remedial treatment operation to treat over 8,000 tons of impacted soil. Through a treatability study, Soli-Bond, Inc. developed a reagent recipe formulation and directed the chemical stabilization. This was accomplished by Soli-Bond, Inc.’s maintained and operated Transportable Treatment Unit (TTU).

All processed soil was utilized as backfill material at the site under the guidelines established by the California Regional Water Control Board.

All relevant regulatory agencies, including the California Regional Water Control Board, the South Coast Air Quality Management District, The State Department of Toxic Substance Control and all local regulatory agencies, were involved in the project from the outset and were satisfied with its outcome. Site conditions were in compliance with all relevant regulatory requirements.

Bircher Riverside Marketplace Development

Kalkaska, Michigan

In 1991, a U.S. cold-storage facility was dismantled in preparation for construction of  a theater and community rail depot in conjunction with development of the Riverside Marketplace Development project. During excavation elevated levels of petroleum hydrocarbons were discovered. Subsequent characterization revealed substantial ash deposits with levels of total and soluble lead and copper in excess of total and soluble threshold limit concentrations (STLC & TTLC). Approximately 15,000 tons were excavated and stockpiled for treatment.

Soli-Bond, Inc. conducted an extensive chemical stabilization treatability study to evaluate the approximate reagent type, recipe, and effectiveness on the contamination present. In addition, Soli-Bond, Inc. was contracted to utilize its Transportable Treatment Unit (TTU) which is permitted through the State of California, Department of Toxic Substance Control (DTSC) for treatment of heavy metals under Permit-by-Rule (PBR).

Remedial actions included screening of all material prior to treatment, chemical stabilization, and stockpiling for successful treatment verification. All 15,000 tons of material was successfully treated over a 10-day period. Upon successful reduction of soluble lead, copper and TPH concentrations, the material was granted reclassification as non-hazardous fill, and approved for use as backfill for parking and building areas.

14 Well Gas Storage Field System

Kalkaska, Michigan

Pitless drilling operation in Michigan consisting of solidification processing and disposal of 8,000 ydsł of salt saturated drilling fluids and semi-solids collected from solids control equipment. This processing was accomplished through use of Soli-Bond, Inc.’s SB-7 processor unit without the use of reserve pits. The use of a conventional pit system was ruled out due to the use of only three drill pads for all of the wells. One pad consisted of seven (7) well heads. Further, this project was located in an extremely environmentally sensitive area of Northern Michigan and conducted during peak tourist season.

The wastes were collected, processed, and transported off-site and never allowed to touch the ground. During the project, extreme weather conditions (late fall, early winter) increased the difficulties associated with this type of work. The Soli-Bond system was able to respond to these additional challenges and successfully complete the project without environmental damages or nearby resident or tourist complaints.

General Motors Luxury Car Division Assembly Plant

Hamtramck, Michigan

Automotive paint sludge needed to be solidified to meet landfill requirements. Soli-Bond, Inc. developed a cost-effective recipe that was sensitive to volume increase restrictions. The on-site technique employed the use of Soli-Bond, Inc.’s collection and conveyance drag tank unit coupled with the SB-7 mobile solidification processor. The processed sludge was conveyed directly to 20-yard roll-off boxes for direct landfill disposal.

The sludges were delivered to the collection drag tank unit via a Bobcat loader and Power-vac tank trucks. Both delivery systems dumped directly into the drag tank conveyance unit. The conveyance unit fed the SB-7 solidification processor where an adjustable amount of solidification reagents were added and thoroughly mixed into the sludge. On-site quality control for recipe and maximum container load capacity was implemented and resulted in a successful cost reduction project. Two hundred fifty (250) tons of total weight was processed and completed on schedule and within budget. All materials passed landfill requirements and went directly to the disposal cell.

Pitless Gas Well Drilling Operation

Bakersfield, California

The drilling of four (4) 10,000' gas wells was conducted not using the conventional technique of a reserve pit or recirculating sump. In place of a conventional pit system, Soli-Bond, Inc. utilized its collection system to manage all of the semi-solid wastes generated by the solids control equipment.

These wastes were processed into a reusable soil-like material utilizing Soli-Bond, Inc.’s mobile SB-7 solidification processing unit. In addition, approximately 16,000 BBLs of pumpable drilling fluids were solidified directly and turned into an easily handled, reusable solid.

Approximately 35,000 BBLs of semi-solids and fluids were economically processed and reused on site. No fluids or wastes were hauled off during this drilling project.

Delco Chassis Wastewater Treatment

Dayton, Ohio

650 tons of F037 oily wastes were processed to meet Universal Treatment Standards (UTS) for lead. Total lead concentrations exceeded 8,000ppm and were found to be extremely sensitive to high Ph solubilization. Soli-Bond, Inc. developed a recipe and on-site technique to effectively process the waste to below LDR thresholds.

The process included a quality control procedure to ensure the waste qualified for direct landfill disposal before leaving the site. Further, the technique developed was on-site-friendly with complete flexibility for physical sludge characteristics and process production rate fluctuations. The sludges ranged from sticky, tarry sludge to pumpable fluids with less than 10% solids.

The project was completed on schedule and no materials were rejected at the disposal facility where they were again tested for LDR thresholds before being placed directly in a disposal cell.

Ultrapower - Chemical Fixation/Stabilization Lead Contaminated Fly Ash

Woodland, California

Over 3,500 tons of lead impacted fly ash was generated at a co-generation power production facility. The average level of contamination was 18mg/L STLC. Remediation was necessary to comply with the Placer County Environmental Health Department and Regional Water Quality Control Board agency guidelines. It was determined that the ash would be stabilized and used as sub-base for the planned yard improvement.

Soli-Bond, Inc. performed a treatability study prior to ash treatment to determine the required ratio of reagent to ash, which would ensure the soluble lead stabilization to below the regulatory limit of 5mg/L STLC. All analysis for soluble lead were by the California WET method.

Chemical stabilization of the lead contaminated fly ash was accomplished by mixing contaminated ash, reagent, and water as needed with Soli-Bond, Inc.’s TTU permitted equipment at a ratio determined by Soli-Bond, Inc.’s treatability study. The tasks were as follows:

• Receive reagent and blow into Soli-Bond, Inc.’s storage silo.

• Load ash into TTU hopper with front-end loader.

• Blend determined quantities of reagent, contaminated ash, and water in TTU.

• Discharge treated material and transport to crews performing backfill and

compaction activities.

• Keep daily log of material processing operations.

• Map treated material placement in reference to confirmation sampling.

The treated fly ash was carefully placed and compacted on a plastic liner; rough graded and cured concrete slabs and asphalt paving over the ash were constructed in accordance with agency approval.
