ENVIRONMENTAL ENGINEERING & CONSULTING SITE ASSESSMENT/REMEDIATION/BROWNFIELDS

Site Assessment/Remediation/Brownfields

Recognized academic achievement, high quality supplemental training, and many years of diverse experience have enabled EE&G staff to compile a highly successful track record for investigation, evaluation and remediation of soil, sediment, and groundwater contamination. Projects commonly involve petroleum hydrocarbons, chlorinated solvents, PCBs, or heavy metals. The work is performed in compliance with federal, state, and local regulations either directly for a facility owner or in response to an environmental enforcement process.

Site Assessment Reports

Identifying, delineating and quantifying the environmental issue can be the most critical component of environmental site remediation. Environmental issues are often hard to see and therefore difficult to define (Such as asbestos or toxic mold). EE&G approaches the site assessment keeping the client’s goals and objectives in mind. Each assessment is prepared taking into consideration the client’s intended use of the site, the site’s location as it relates to other industry uses, jurisdictional requirements, and the client’s risk tolerance. Each assessment is tailor made for each site to delineate the vertical and horizontal extent of contamination as well as identifying the contaminants and comparing them to regulatory standards.

Remedial Action Plan (Designing/Implementation)

Just as assessments are tailor made for each site, so is the Remedial Action Plan (RAP). EE&G works closely with the client to minimize disturbance of site operations, or incorporate the remedial effort into site development plans. A successful site remediation results in regulatory approval. The receipt of a "No Further Action" letter from an agency brings peace of mind and allows real estate transactions to move forward. EE&G familiarizes itself with the appropriate regulatory requirements and works closely with the jurisdictional agency to insure the remediation action plan incorporates the necessary items for agency approval, incorporates the appropriate regulatory action levels, and operates in compliance with all permits and waste management requirements.

Natural Attenuation Monitoring

Often site remediation will result in substantial reduction of contaminant levels but falls short of the clean up target levels. In cases where monitoring results consistently show little reduction in the contaminant level, EE&G may propose discontinued operation of the remediation system and recommend that the remaining contaminants be left in place to reduce naturally overtime. Monitoring will continue until it can be shown that the levels continue to decline without additional remedial effort and the regulatory agency approves closure.

Risk Based Corrective Action Plan

Clean up of a contaminated site to government soil or groundwater standards is often cost prohibitive and may not be technically possible. Moving or replacing an underground storage tank is quite a task. Preparation of a site-specific Risk Assessment may be used to develop alternate site remediation target levels, which are less stringent and more financially and technically feasible. EE&G personnel have successfully negotiated risk-based remedial target levels with regulatory agencies to reduce client's costs while achieving a reasonable cleanup of the environment. These are then incorporated into a site-specific Corrective Action Plan for agency review and approval prior to implementation.

Engineering/Institutional Controls

At times contamination cannot be remediated to the satisfaction of the regulatory action levels or contaminants may migrate onto the site from off site sources. Some environmental issues occur naturally and cannot be removed such as radon or methane gas. When this occurs EE&G designs engineering controls to mitigate the affect of the contaminant to the site. EE&G has been successful in designing and implementing controls including active or passive gas collection systems, slurry walls to prevent groundwater migration, land surface caps to reduce exposure to soil contaminants, and other mitigating measures to reduce liability and risk for the client.

Source Removal

Removing the source of the contaminant is often the quickest way to resolve ongoing pollution problems and minimize environmental liability. EE&G has the capability of implementing the Remedial Action Plan whether it involves the removal of underground storage tanks or impacted soils. EE&G can take the project from assessment through to source removal and regulatory closure.

Regulatory Compliance

Preventing environmental contamination before it occurs is the most cost-effective approach to environmental management. EE&G has long recognized the value of environmental compliance audits for limiting liabilities, reducing enforcement actions, insurance and waste management costs, and even improving the efficiency of an operation. EE&G personnel have extensive experience performing compliance audits at commercial and industrial facilities. Compliance audits involve an assessment of a facility’s overall waste management, housekeeping, and industrial hygiene practices relative to applicable regulations. Compliance audits provide an opportunity for the owner to take corrective actions on their own without the complexities, costs, and delays of government oversight.
