Environmental Remediation Management has had the privilege of working as a contractor for numerous clients in the San Diego and Southern California areas. The following links describe some of Environmental Remediation Management's successful projects, providing examples of the wide variety of project types, decontamination procedures, environmental concerns, and management experiences with which Environmental Remediation Management has been involved over the past 30 years in operation.
metropolitan water district
PROJECT NAME: Metropolitan Water District of Southern California-Pump Station Oil Filled Circuit Breaker Disposal
CLIENT: Southern Contracting Company
CONTRACT AMOUNT: $500,000.00
DATE OF COMPLETION: 05/30/2005
Metropolitan Water District of Southern California contracted with Southern Contracting Company to remove and replace 230kV and 69kV oil circuit breakers during two 21-day outages. Environmental Remediation Management was the selected team member to perform environmental services and demolition. The aqueduct is 272 miles long and consisted of five pump stations, Intake, Gene, Iron Mountain, Eagle Mountain and Hinds.
Environmental Remediation Management removed 3 sets of 69Kv circuit breakers at the Intake Pumping facility from the top of the mountain to ground level. This was accomplished by draining PCB contaminated oil from switches on the mountain into drums at ground level. To accommodate the load capacity of the crane, Environmental Remediation Management torch cut the switch gear into manageable pieces. Maxim Crane provided a 500-ton crane with 284,000 pounds of counter weight. The crane reached 284 feet horizontally and 120 feet vertically to pick up a maximum of 4,000 pounds of circuit breaker pieces per pick.
The remaining pump stations required pumping, transportation and disposal of 6,000 gallons of oil from six separate circuit breakers at each facility. After oil was drained, Environmental Remediation Management cut the circuit breakers from mounting brackets and disassembled them for removal by a 50,000-pound rated forklift operated by Environmental Remediation Management.
Port of San Diego
PROJECT NAME: Port of San Diego
SDG&E Tank Floor Cold Cutting
National City, CA
CLIENT: Brown & Caldwell
CONTRACT AMOUNT: $32,000.00
DATE OF COMPLETION: 04/30/2008
The following information details Environmental Remediation Management's work with the Port of San Diego. It highlights the use of steel-cutting services, which are offered by Environmental Remediation Management, to address specialized client needs.
Environmental Remediation Management was contracted to cold cut thirty-two 14” diameter holes through former crude oil steel storage tank bottoms.
Because petroleum hydrocarbons were present under the tank floors, Environmental Remediation Management used ultra-high-water pressure with grit to cold cut various locations of the tank bottoms so soil samples could be taken to determine the extent of contamination.
Environmental Remediation Management also performed the following services:
- Obtained permits for fire hydrant usage
- Drummed excess water contaminated with hydrocarbons
- Welded tabs (offsite) on cutout center pieces so they could be put back in place.
Environmental Remediation Management can readily utilize steel-cutting processes to solve many demolition projects and other facility needs.
PROJECT NAME: Middletown
CLIENT: Brown & Caldwell
CONTRACT AMOUNT: $900,000.00
DATE OF COMPLETION: 02/28/07
Environmental Remediation Management was contracted by Brown & Caldwell to decontaminate storm drains containing PCBs. The work included isolation of the storm drain system by inflatable plugs at each end and installation of an automated pump bypass system. Once the storm drains were isolated, Environmental Remediation Management hydroblasted the entire circumference of the pipeline using a centralizer and swivel, set to rotate at an efficient RPM to control the rate of surface cleaning. A high velocity vacuum truck collected the water, sediment and contaminated wastes. The waste water, sediment and contaminated waste was processed through a waste treatment system to remove contaminates from the water. Sediment was stockpiled, sampled, and analyzed for disposal. The water was disposed of at a local municipality. Environmental Remediation Management provided transportation and disposal of the sediment.
- Decontaminated 750 feet of 54” diameter storm drain piping
- Decontaminated 2,700 feet of 60” diameter of storm drain piping
- Decontaminated 4,800 feet of 4" to 24" diameter conveyance storm drain piping
- 220 tons of contaminated sediment removed from storm drains and transported to an off site disposal facility
PROJECT NAME: Tow Basin
CLIENT: Port of San Diego
CONTRACT AMOUNT: $150,000.00
DATE OF COMPLETION: 12/30/03
The San Diego Port Authority contracted with an environmental contractor to remove 68,000 square feet of PCB containing paint. Environmental Remediation Management was selected by the environmental contractor to do the toughest part of the project, remove all PCB containing paint from the ceiling of the facility.
Environmental Remediation Management’s scope of work included setting up a rolling scaffold with a water recovery system to divert and capture paint, concrete sludge and water. Because of irregular surfaces Environmental Remediation Management was required to use guns with rotating nozzles. This process is the least favorite for any hydroblasting contractor but is the only method that is effective enough to achieve Department of Toxic Subsistence (DTSC) decontamination requirements.
When Environmental Remediation Management completed hydroblasting the ceiling, samples were taken and confirmed PCB decontamination was satisfactory. The building was demolished and disposed of at a local landfill as non-hazardous saving the client in disposal costs.
Environmental Remediation Management can readily address PCB-contamination concerns as well as a wide variety of other hazardous material needs.
PROJECT NAME: ST Microelectronics
Rancho Bernardo Facility Decontamination
CLIENT: DPR Construction
COMPLIANCE MANAGER: Advanced Chemical Safety
CONTRACT AMOUNT: $430,000.00
DATE OF COMPLETION: 03/30/2002
Environmental Remediation Management was contracted to decontaminate and dismantle ST Microelectronics micro-processor manufacturing facility. ERM’s work included removal of all chemical processes and conveyance systems. This project highlights Environmental Remediation Management's abilities to partner with safety and environmental professionals for complex work that involves chemical hazards and regulatory compliance concerns.
During this project, Environmental Remediation Management decontaminated process systems that contained the following chemicals:
- Hydrofluoric acid
- Sodium hydroxide
- Inert gases
- Pyrophoric gases
- Various heavy metals
These process systems still had much chemical residue. After decontamination was complete, equipment of resale value was sold. The remaining equipment was scrapped as non-hazardous waste. Therefore, hazardous waste disposal was a minimal portion of the projects overall costs. Environmental Remediation Management worked closely with Advanced Chemical Safety to address chemical hazard and regulatory compliance issues.
Advanced Chemical Safety was retained by ST Microelectronics, Inc. to provide technical guidance to plant closure activity and to certify that the plant site was safe and free of undisclosed hazards at the time of the plant's closure. Advanced Chemical Safety developed a detailed Site Closure Plan; Environmental Remediation Management was then commissioned to implement the closure activity.
While the complete site was evaluated to gauge clean-up requirements, major focal points of decontamination efforts were the production-related areas and the Industrial Water Pad. The lack of local, state, or federal guidance criteria for decommissioning a facility (in regards to the level of chemical residue) means that the owners of facilities undergoing closure must establish reasonable criteria. Advanced Chemical Safety set these criteria for the ST Microelectronics site, which ensured that the facility was free of chemical residues to the lowest, realistically achievable level. Environmental Remediation Management exceeded those standards. The site was certified free of hazardous materials and all chemical residues were reduced to below the established criteria level.
As the decommissioning work progressed, ST Microelectronics managers decided to remove all of the building equipment, except those items needed to maintain the interior conditions. This increased the scope of the certification project, but ultimately rendered all locations free of contaminants. Despite the change in plans, the project was completed on-time and on-budget.
As shown above, Environmental Remediation Management provides a wide range of services that can address complex sites that are chemically contaminated. Environmental Remediation Management can manage complex projects in an economical and environmentally sound manner, minimizing down-times and other problems related to equipment decontamination, building renovations, or other remediation or upgrade needs that facilities may have. Environmental Remediation Management will ensure all work is timely, conducted by highly trained personnel, and completely meets safety and environmental health regulations.
PROJECT NAME: General Dynamics -Lindbergh Field/Harbor Drive Facility Decontamination
OWNER: General Dynamics
CLIENT: ICF Kaiser Engineers, Inc.
CONTRACT AMOUNT: $1,600,000.00
DATE OF COMPLETION: 09/30/97
General Dynamics contracted with ICF Kaiser Engineers, Inc. to decontaminate and demolish structures located at the Lindbergh Field and Harbor Drive sites in San Diego. Environmental Remediation Management was then selected by ICF Kaiser Engineers, Inc as the contractor to perform environmental demolition and remediation. This project underscores Environmental Remediation Management’s capacity to handle complex projects with rigorous schedules involving other contractors.
The Lindbergh Field site consisted of 91 acres, 32 buildings, and 2,836,000 square feet of building space. The Harbor Drive facility consisted of 4 acres, 4 buildings, and 34,500 square feet of building space. Project tasks were specific to each building and the former processes within each building. Site wide concerns were addressed for each building, as well as areas-of-concern pertinent to that facility or process area. The remediation program of each area-of-concern was tailored to address the array of potential chemical contamination and physical hazards present.
Due to the nature of the General Dynamics’ remediation program, detailed documentation had to be submitted by all contractors. This documentation included items such as a comprehensive Health & Safety Plan, employee records related to training and medical surveillance, security clearances, and schedules. Environmental Remediation Management's Project Manager attended all contractor-client weekly meetings and provided expertise in environmental issues to the general contractor throughout this project.
One key aspect of this project was the disposition of building equipment in a environmentally sound, yet cost effective manner. For example, the majority of equipment was sold following decontamination or consolidated and sold as non-hazardous scrap metal. Only a small percentage of equipment could not be decontaminated and required disposal as hazardous waste. Waste that was recycled included light bulbs and tubes, mercury switches, PCB contaminated equipment, and oil and water waste.
Environmental Remediation Management's site plans addressed hazardous waste management effectively. Rinse water from decontaminating the process plating lines was pumped to the on-site wastewater treatment plant where it was processed. Environmental Remediation Management was responsible for packaging and labeling all waste generated during remediation.
In summary, significant project accomplishments by Environmental Remediation Management include:
1. Environmental Remediation Management recommended a recycling process for PCB-containing equipment rather than using landfill disposal as identified by the client. This method eliminated the cost of hazardous waste disposal.
2. Environmental Remediation Management modified a hydroblasting method for machine pits, sumps, trenches, and floors to increase cleaning efficiency and reduce the volume of oily waste water. This modification resulted in completing work ahead of schedule and reducing hazardous waste recycling costs.
3. Environmental Remediation Management’s cleaning method for concrete sumps, pits, and trenches containing oily residue eliminated contamination so that the concrete was non-hazardous and could be crushed for reuse or disposed in a local municipal landfill.
4. Equipment that could not be decontaminated cost effectively was crushed before loading it into bins. This method reduced the volume of waste resulting in a savings of transportation costs.
5. Environmental Remediation Management provided hard and soft demolition services to other team contractors when hazardous materials were present. Demolition activities included: cutting plating tank supports, removal of non-load bearing structures inside buildings, removal of load-bearing support structures associated with anodizing line, removal of false ceilings to access lights, and the removal of non-load bearing walls and ceiling to access hazardous substance containing equipment.
Environmental Remediation Management can address small-and large-scale remediation projects. The company is able to set-up and support operations in San Diego, San Diego County, and the greater Southern California area (Los Angeles, Orange County, Riverside, San Bernadino, and Ventura Counties). Environmental Remediation Management also serves facilities in Arizona and Nevada. Please contact us for further information on the General Dynamics project, or on any other matter.
Environmental Remediation Management received a Letter of Recommendation from both General Dynamics and ICF Kaiser Engineers for our work on this project.

JF Shea Construction, Inc. encountered a 78” diameter concrete conveyance pipe that had deteriorated concrete and rusted rebar from exposure to chlorides. Environmental Remediation Management was contracted to hydro blast and remove deteriorated concrete down to sound concrete and polish rebar that had rusted. Environmental Remediation Management removed up 3” of the deteriorated concrete along with contaminates, past the rebar that provided a good bonding surface and clean rebar to a white metal finish. JF Shea was able to weld new rebar to the existing rebar and patch the pipe.
MORE ON HYDRODEMOLTION:
During hydrodemolition, high velocity water jets are used to break apart concrete for removal, or to prepare concrete surfaces for further work. There are many practical advantages to hydrodemolition:
- It eliminates the disruptions associated with vibrations from mechanical methods.
- It allows for the select removal of deteriorated material while leaving sound concrete intact.
- It leaves reinforcing elements and other embedded metals clean and undamaged, while eliminating the need for sandblasting.
- When used for surface preparation, it leaves an irregular surface area ideally used to create a strong mechanical bond utilizing a wide variety of techniques.
Environmental Remediation Management is able to readily develop hydrodemolition protocol to address each client's individual needs. The staff accesses each site carefully, selecting the personnel, methods, and hydrodemolition equipment for the surface preparation most suited to the area. Environmental Remediation Management can handle operations in difficult-to-access areas, while minimizing exposures to operators and surrounding areas. As needed, the water is reclaimed.
Environmental Remediation Management can quickly assess the appropriate hydrodemolition strategies for a wide variety of client needs. The company is positioned to perform hydrodemolition projects in San Diego, San Diego County, and the greater Southern California area (Los Angeles, Orange County, Riverside, San Bernardino, and Ventura Counties). Environmental Remediation Management also serves facilities in Arizona and Nevada.
