The investigative process is never a routine sampling procedure, and every case must be treated individually. OHC has assembled a team of experts to address IAQ issues. The team consists of a Certified Industrial Hygienist (CIH), a Registered Architect (RA), a Certified Indoor Environmentalist, and senior industrial hygienists with a combined experience of 80
years in IAQ investigation and resolution.

Asbestos Consulting Services

OHC is responsible for site and facility surveys, or verification of existing surveys, prior to acquisition, renovation, or demolition; remediation design; contract administration; and construction supervision and monitoring. OHC has also acted as the construction manager on several projects, as a turnkey operation for the remediation database to track their inspections and periodic training.

 

OHC works closely with architectural firms providing them with proper abatement specifications written once the consultation has commenced.

Lead Surveys

OHC has always utilized state-of-the-art techniques and procedures to identify, assess, and analyze for lead. Additionally, OHC utilizes only American Industrial Hygiene Association and environmental lead proficiency analytical testing accredited laboratories for all sample analysis.

 

OHC makes use of the Niton XL309 and XLP 300A instruments in the field to measure for lead-based paint and follows these results up by bulk sample analysis, when necessary, utilizing atomic absorption spectroscopy.

Environmental Compliance Audits

Businesses, corporations and government entities that engage in industrial activities most likely will have an environmental impact and thus need a system to ensure environmental stewardship and compliance are part of the fabric of doing daily business. OHC follows the guidelines and procedures developed by the EPA under the Office of Pollution Prevention and Toxics (OPPT). In addition, OHC advocates using the ISO-14000 series of standards and requirements as guidelines to developing effective environmental management policies and systems.

Chemical and Fuel Spill Response & Evaluation and Clean-Up Management

The release and spill of hazardous chemicals, heavy metals, VOC’s, and pesticides can pose a health risk to workers in the immediate vicinity and to the environment. OHC’s staff has responded to chemical and petroleum releases. In each case we have evaluated the spill, planned the clean up, and remediated the contamination. OHC’s Project Managers and Engineers will ensure that the proper steps are taken to protect the public and any workers involved and then manage the effective cleanup of any spill or release. OHC’s staff is well versed in the various containment methods used in petroleum, mercury, acid, and other hazardous material release situations. All of our key staff has OSHA HAZWOPER training. This training also includes operations at sites covered by the Resource Conservation and Recovery Act (RCRA) and at uncontrolled hazardous waste sites. OHC is thoroughly familiar with the requirements for working at Treatment, Storage, and Disposal facilities (TSDs) regulated by EPA 40 CFR 260 to 282. In addition, we have received training and have experience with the Department of Transportation requirements for transportation of hazardous materials.

Environmental Site Assessments

OHC follows the ASTM E 1527-00 and ASTM E 1528-00 standards in the completion of the Phase I Environmental Site Assessments and other assessments for the transaction screening process. We follow these standards as they were written to establish good site assessment practices to qualify for the innocent landowner defense amendment as mandated by CERCLA liability to satisfy the due diligence responsibilities of participants in commercial real estate transactions.

 

OHC has completed environmental audits of large acreage projects and is thus familiar with the necessary steps to ensure that the client has exercised proper due diligence. In particular, OHC ensures that adequate limits are used in the radius of search. OHC determines the search distances from the property by taking into account the geometry and hydrology of thesites. For example, elongated geometries require special approaches to ensure an adequate distance outside the subject area is considered. Simply using the center point may miss potential problem areas.

 

A qualified OHC environmental professional schedules and completes interviews with the present owners and occupants. The purpose of the interviews is to obtain current and past contamination information relating to the site. Review of aerial photographs to examine past land use, review of local, state and federal records (UST, CERCLIS, NPL LUST, etc.), review of use of adjacent sites, review of potential receptors and wetlands. Existing structures, tell tale vents or pads or any other structure that may provide information regarding the possible use of hazardous material use will be evaluated. Individuals in the surrounding area will also be interviewed to provide as much information as possible regarding the history of the potential site. The field visit by the OHC environmental professional will also encompass the nature of the surrounding area and the various facilities that have a potential to impact the site.

 

If during these reviews, OHC finds that there is a potential for uncontrolled hazardous waste on the site, a more detailed Phase II is recommended. This phase requires collection of field data using soil borings, well installation, soil and groundwater sampling, use of direct push technologies and waste characterization. Once the extent of contamination is defined, OHC can perform a Phase III design of a remedial action to correct the problem. OHC can also manage the remediation of a hazardous waste site. OHC completes one to two studies per month from Phase I to Phase III for many tank removal projects.
