Environmental services by E&LP

Engineering & Land Planning (E&LP) professionals provide long-term leading edge remedial investigations that lead to cost effective site remediation. We work closely with project stakeholders to develop cost-effective site closures and gain regulatory compliance, promoting a cost-conscious approach to site remediation. E&LP possesses a wide range of expertise in Brownfields, Superfund sites, RCRA, and Tank Farms.

Phase 1/Preliminary Assessments/Prop Transactions

E&LP regularly supports lending institutions, law firms, buyers and sellers of real property in assessing potential environmental liabilities during mergers, acquisitions or divestitures.

We understand that the objective of Property Due Diligence is to define the potential liabilities, from a costs perspective, associated with the purchase and/or sale of real property. Our scope of services is based upon the specific needs of the transaction, and can range from initial transactional screens of property(ies) to ASTM-conforming Phase I Environmental Assessments, Preliminary Assessments and focused site investigations.

In addition, our Due Diligence practice also includes applicability determinations and report filings associated with transactions that trigger, or appear to trigger, the NJDEP compliance actions of the Industrial Site Recovery Act (ISRA), formerly ECRA.

Site Investigation and Remediation

E&LP provides a wide range of remediation alternatives in order to create custom, site specific remedial actions to achieve our client’s goal. Our staff performs detailed site investigations to evaluate the most appropriate remedial action for site closure. In addition to soil and groundwater investigations, E&LP has performed a myriad of vapor intrusion studies throughout New Jersey, which have included both in-door air sampling and sub-surface vapor collection systems.

E&LP has designed and implemented numerous site remediation efforts that have resulted in site closure through the excavation of impacted material as well as through the use of bio-remediation and/or chemical oxidation. Often, the most cost effective means is a combination of physical removal, coupled with either bio-remediation or chemical oxidation, especially when significant structural or other site constraints are present.

For sites where an exposure pathway has been established, from contaminated subsurface to vapor impacts within structures, E&LP has designed and installed retrofitted systems to mitigate the vapor migration into the existing building. E&LP has also designed vapor mitigation systems consisting of a sub-surface vapor barrier and ventilation systems for large, retail outlets constructed over contaminated soils.

We recently completed a project where soil excavation was used on the exterior soils of a residence to address fuel oil contamination. In order to avoid significant additional costs to excavate below the basement structure, including basement restoration, horizontal piping was installed to treat the soils beneath the house with chemical oxidation.

LSRP

The Site Remediation Reform Act (SRRA) became fully effective on May 7 2012, resulting in a quasi-privatization of environmental regulatory compliance under the supervision of a qualified Licensed Site Remediation Professionals (LSRPs) in lieu of NJDEP Case management personnel. This program has been partially in effect under temporary LSRPlicensures since May 2009. Since the inception of the program E&LP has closed out the environmental regulatory compliance of numerous sites by issuing Response Action Outcome (RAO). A (RAO) is equivalent to a No Further Action (NFA) letters formally issued by the NJDEP which certifies the site as clean and remediated in accordance withNJDEP regulations.

Air Quality/Mold

E&LP provides vapor intrusion, indoor air quality and mold testing services. Vapor intrusion is the migration of vapors from contaminated soil and ground water into a building leading to risks of exposure to its occupants. E&LP performs vapor intrusion testing that may include collection of sub slab soil gas and indoor air samples to determine if vapor intrusion pathways are present.

For sites where an exposure pathway has been established, from contaminated subsurface to vapor impacts within structures, E&LP has designed and installed retrofitted systems to mitigate the vapor migration into the existing building. E&LP has also designed vapor mitigation systems consisting of a sub-surface vapor barrier and ventilation systems for large, retail outlets constructed over contaminated soils.

In addition to vapor intrusion caused by volatile organic compounds, E&LP also performs indoor air quality (IAQ) investigations for airborne fungi and viable mold. Sampling and analysis is performed in accordance with National Institute of Occupational Safety & Health (NIOSH) recommendations. We perform testing via both air sampling as well as surface sampling for fungi and mold. E&LP also develops mitigation plans to address the sources of and areas of viable mold to minimize potential respiratory and allergy issues.
