Project Description: Under this contract, Environet prepared a National Environmental Policy Act (NEPA) Environmental Assessment (EA) for flood control of Iao Stream on Maui. The EA analyzed the environmental impacts of the proposed alternatives and identified unavoidable adverse environmental effects should the proposed action be implemented.

 

A wide range of alternatives were considered ranging from construction of a concrete lined bottom to more environmentally sensitive solutions stressing the maintenance of ecological balance during low stream flow conditions. The EA developed potential mitigation measures for unavoidable impacts, examined the relationship between short-term uses of the human environment and the maintenance and enhancement of long-term productivity, and identified irreversible or irretrievable commitments of resources which would be involved if alternatives were implemented. The EA also identified direct effects and their significance, indirect effects and their significance, possible conflicts between the proposed action and objectives of Hawaii s land use plans and policies, urban quality, historic and cultural resources, and socioeconomic and market conditions.

 

Field visits were conducted to gather existing data required to complete an analysis of project impacts as required by the Council of Environmental Quality (CEQ), NEPA and Corps Engineering Regulations (ERs). Public meetings were conducted in compliance with NEPA regulations.

A Finding of No Significant Impact document was prepared that serves as the Army Corp s written public record explaining the rationale behind selection of the chosen course of action.

Ms. Uyen Tran

(808) 438-0512

 

Project Description: Environet conducted an Environmental Compliance Assessment (ECA) for twenty-one facilities operated by the State of Hawaii, Department of Transportation, Highways Division. Seven of the facilities were located on the island of Oahu, six on the island of Hawaii, two on Maui, two on Kauai, one on Molokai and one on Lanai. The assessment was done to assist the Department of Transportation in achieving compliance with environmental laws and regulations, including the United States Codes (USC), the Code of Federal Regulations (CFR), and specifically the Hawaii Administrative Rules (HAR), and City Ordinances and Codes.

 

Environet began by updating the Federal ECA TEAM Guide which has served as the basic protocol for prior assessments. This guide was supplemented by incorporating State and local environmental laws in areas where there has been a federal delegation of authority or where state and local regulations are more stringent than Federal regulations.

 

Environet led a team of assessors in the field which included the U.S. Army Corps and sub-consultant, Tetra Tech, Inc. The on-site assessment work was based on record searches, visual surveys of facilities, interviews with the facility managers, and performance of site surveys using federal, state, local and HDOT specific regulations as the basis for findings. Interaction with facility staff was conducted to increase staff awareness and involvement regarding environmental management and compliance requirements.

 

A Microsoft Access data base software program was developed that streamlined and standardized the assessment process and subsequent manipulation of data during the project. The database was populated through a web-based interface and used by team members to input individual findings. Photographic documentation of findings were uploaded and stored. Output from the software program was used to generate the draft and final Environmental Compliance Assessment Report (ECAR).

 

The draft and final ECAR prepared detailed the findings of the on-site assessments. The ECAR cited the appropriate regulations associated with environmental findings and contained recommendations for findings of non-compliance. An out-briefing was held with the Army and the client, HDOT, which focused on how the State could efficiently adopt a strategy for environmental compliance through development of a corrective action plan.

Project Description: Environet prepared a National Environmental Policy Act (NEPA) Environmental Assessment (EA) for a Section 206 Aquatic Ecosystem Restoration (AER) project conducted for the Saipan Lagoon ecosystem. The ecosystem has degraded over the last 15 years due to stormwater and sediment runoff and sanitary sewer overflows resulting in sediment accumulation and algae blooms along the coastline. The purpose of the AER was to restore the degraded ecosystem structure, including its hydrology and plant and animal communities, to a less degraded and natural ecological condition. The EA explored four separate restoration alternatives, possible conflicts between the proposed action and objectives of the Commonwealth of Northern Mariana s land use plans and policies, and identified unavoidable impacts and potential mitigation measures for each of these impacts. An incremental cost analysis was performed of the various restoration alternatives in an effort to optimize the environmental benefits gained against the actual restoration costs.

 

Environmental studies were conducted in the project area in order to establish baseline conditions in the nearshore lagoon environment. Baseline studies included water quality sampling and analysis (stormwater and groundwater), sediment sampling and analysis, watershed hydrologic analysis, marine flora and fauna survey, and marine habitat mapping. A conceptual design of recommended drainage improvements and structures to mitigate sediment runoff to the lagoon was prepared. A monitoring plan was developed to measure the effectiveness of the proposed improvements.

Project Description: Environet prepared a user-friendly, integrated GIS and electronic database system capable of accepting all geotechnical and environmental information compiled by the Far East District of the United States Army Corps of Engineers (FED). The GIS/database system integrated drinking water chemistry datasets, groundwater chemistry datasets, soil chemistry datasets, and borelogs. Prior to the completion of this project, the client had no way of accessing the voluminous historic geotechnical, geologic and chemical data that had been collected during previous investigations conducted over the past decade an military installations located throughout South Korea..

This project also involved the preparation of a report summarizing the impact of fuel storage facilities (USTs, ASTs) on groundwater aquifers underlying thirteen USFK installations located throughout South Korea. Information on fuel and groundwater usage and known contamination sites at the installations were compiled from base records and from interviews with base personnel. A groundwater vulnerability report was prepared that forecasted the potential impact of future fuel system failures on the health of military personnel, the integrity of the installation groundwater resource, and political relations between the United States and the Republic of Korea. Recommendations were prepared detailing the upgrades and replacements required to the existing fuel systems.

 

The information compiled during this study was used to obtain additional funding to upgrade fuel storage facilities at military bases throughout South Korea. The GIS/database system developed allowed FED personnel to more efficiently access all geotechnical and environmental information developed for future projects.

Project Description: As the prime contractor, Environet managed logistics, subcontractors and coordinated all project work with Federal, State, and Army personnel for a large site characterization and remedial action conducted at six solid waste management units and three areas of interest on Johnston Atoll. Contaminants of concern included PCBs, PAHs, heavy metals, SVOCs and chemical warfare agents and their degradation products. A sampling work plan, quality assurance/quality control plan and health and safety plan were prepared for the investigation sites. Topographic and geophysical surveys were conducted on all nine sites. The lateral and vertical extent of contamination present at seven of the nine sites were characterized by drilling over 60 borings and by multi-media sampling. A detailed remedial action work plan was then prepared based on sample results and previous sampling investigation data. The work plan detailed the lateral extent and depth of excavation work required, as well as the excavation methods to be used to minimize the amount of fugitive dust generated during excavation. Environet coordinated the complex task of mobilizing and shipping excavation equipment used to remediate the sites. Backhoes, forklifts, a dump truck, a refueling truck, a Super Sack loading hopper, and a compaction roller were delivered via barge to Johnston. A total of 960 tons of contaminated soil was removed from five discrete sites on the island. The maximum depth of excavation was 6 feet and all sites were restored to original condition by backfilling the excavations with six-inch lifts of clean limestone sand. In addition to the soil, a total of 15 tons of contaminated treated wood was boxed for off-island disposal. Verification sampling was conducted from the base of the excavations to verify that all contaminated soil had been successfully removed from the sites. The field portion of this project was completed in a 3 1/2 week period.

Environet managed the entire project, subcontracting efforts, field activities and closure reporting with in-house staff. Environet was tasked with the site characterization, remedial design, a RCRA removal action, confirmation testing, and final report writing for remedial work conducted at the nine USACAP environmental sites. A Public Notice Plan (PNP) was prepared in accordance with applicable requirements of RCRA. Environet personnel coordinated and managed five sub-contractors on this project, including drilling, laboratory, barge and trucking companies as well as heavy equipment operators. During the course of the project, Environet personnel negotiated soil remediation action levels with U.S. Fish and Wildlife personnel. A total of 975 tons of hazardous and non-hazardous contaminated soil and treated wood was excavated, packaged and transported to the mainland United States for disposal. The entire project was completed in less than six months time in order to meet the USACAP command decommissioning date on Johnston Atoll of September 2001.

Project Description: Environet served as the Prime Contractor responsible for the location and removal of USTs and associated pipeline present at Fort Shafter Flats, Helemano Military Reservation, Tripler Army Medical Center and Wheeler Army Air Field. The work was conducted under the provisions of Section 106 of the National Historic Preservation Act. A project specific safety plan, sampling and analysis plan and work plan was prepared for the project. Environet prepared all of the necessary permits, notification of closure documents and obtained all required clearances.

The excavated tanks and piping were cleaned prior to disposal. Hazardous and non-hazardous soil encountered during excavation was stockpiled and characterized prior to disposal. The excavated sites were backfilled and restored to pre-existing conditions. A large concrete pad was demolished and disposed at a local landfill. The tanks and pipelines were excavated, removed, cut, cleaned, and disposed of in accordance with Federal, State, and local laws and regulations. All tank contents, tank rinseate, and tank sludge recovered were properly characterized and disposed of at licensed facilities in accordance with these laws. The location of all soil sampling sites, the ends of the USTs, the course of the removed pipelines and permanent survey monuments were established by a licensed surveyor. Environet provided closure reports for the USTs removed

 

Samples were collected from each end of the UST excavations and from every 20 linear feet of piping, at piping elbows, joints, or fittings. When laboratory or field observations indicated the presence of a release from a UST or piping, Environet notified USACE and State of Hawaii UST program representatives and submitted the necessary State release notification forms. Field observations and analytical laboratory results were used to determine the extent of petroleum-impacted soil at each site and to guide the over excavation of petroleum-impacted soil. Confirmation samples were collected from the over excavation walls to verify that the petroleum constituents present in the excavation were below current State of Hawaii UST program soil action levels. A total of roughly 100 tons of predominately POL-impacted soil was excavated, characterized, and properly disposed of at a licensed facility. A geologist was present during excavation and removal activities to document and identify the impacted soil material encountered during excavation. Each investigation area was backfilled and restored to its previous condition at the end of the investigation. Topographic surveys were done for the removals and the individual soil sampling points. A chain of custody was kept for all samples collected during the investigation which were included in the UST Site Assessment/Closure Report that was prepared for the project.

Project Description: The project involved the design, installation and maintenance of a remediation system to clean-up roughly 50,000 cubic meters of POL contaminated soil and groundwater at a fuel transfer station. The contamination originated from historical leakage from three large USTs and associated piping present at the facility. The project involved a preliminary site visit, installation of a pilot scale test system, design and installation of an injection/extraction system, oil-water separator and monitoring wells, preparation of an operation and maintenance plan for the installed remediation system, and routine monitoring of soil gas for CO2, O2 and hydrocarbons, monitoring soil and groundwater for TPH and BTEX compounds and microbial population, and preparation of a final summary remediation report.

Environet worked with Samsung to design and install the remediation system to treat POL contaminated soils. Approximately 50,000 cubic meters of soil were contaminated with TPH in excess of 500 ppm at the site. Extraction wells and monitoring wells were installed and in-situ respiration testing conducted to determine the field air permeability and hydraulic properties of the shallow aquifer beneath the site in order to determine the required well spacing of the remediation system. A combined soil vapor extraction/bioventing system was installed that allows for the simultaneous extraction of vapor, as well as dissolved and free phase contaminants, from soils and groundwater from the vadose zone, capillary fringe, and saturated zone. The system was a modification of the normal soil vapor extraction and bioventing systems that is particularly effective in soils with moderate permeability. This modified system had higher remediation efficiencies than just soil vapor extraction. Air-injection was conducted in conjunction with extraction of multi-phase contaminants to enhance biodegradation. By August 2003, a total of 12,000 kilograms of JP-8 and diesel free product had been recovered from the site. The recovered free product was transported to Camp Stanton where it was recycled. Water generated during product removal was stored in a temporary water tank where it was analyzed to confirm that it meets effluent wastewater limits in accordance with the Environmental Governing Standard for United States Forces, Korea.
