Large areas of the 100+ year old site were man-made consisting of fill materials placed in Lake Michigan. Hydrogeology was complicated by strong Lake hydrodynamic influences on the saturated zone. BBJ Group professionals designed and installed free product recovery wells with hydrophobic coatings for product separation and air-drive pumps. Within six months, free product in an area impacted by heavy fuel was reduced to a sheen.
Large parts of a century-old facility were man-made, consisting of fill materials placed in Lake Michigan. Free petroleum product was present beneath parts of the site, necessitating RCRA cleanup.BBJ Group professionals were responsible for designing and installing systems for free product recovery. Within six months, free product in an area impacted by heavy fuel was reduced from 1.5 feet thick on the water table to only a sheen.
Property transfer due diligence identified several solid waste management units that warranted RCRA Corrective Action before closing.The USEPA required site investigation, cleanup, and closure. Subsequent BBJ Group investigations identified the extent of impact, determined the geologic conditions controlling migration, and evaluated potential consequences of stormwater runoff. BBJ Group is currently conducting post-closure activities.
Regulatory changes required BBJ Group’s Client to remove or upgrade hundreds of underground and aboveground storage tanks. With little detail provided, BBJ Group estimated costs for five different scenarios, with a low, high, and most-likely scenario for each. The Client used the results to argue economic hardship with the state and offered to negotiate an extended removal schedule. The Client ultimately established an environmental reserve meeting the regulatory requirements.
A former naval station was reopened to residential and other uses. According to the federal and state agencies, groundwater at the site was potentially impacted with substances known to cause cancer and other illnesses.BBJ Group defined cleanup standards based on human health risk assessment data considering “central tendency” and “reasonable maximum exposure” scenarios. The Client assessed development strategies based on these risk evaluations.
BBJ Group found elevated levels of polynuclear aromatic hydrocarbons at a Client’s property. Risk and liability were complicated as the Client was not the current owner, contamination extended off-site, and most of the contamination was in a wooded area.The Client received state approval for voluntary site cleanup and closure under agency supervision. Based on BBJ Group recommendations, the closure strategy saved the Client more than $450,000.
BBJ Group provided decommissioning services for several former cathode ray tube manufacturing facilities. This entailed day-to-day contractor procurement and management; environmental, health, and safety planning and compliance; permitting; and decommissioning; negotiations with local and state regulators; compliance reporting; and Client representation during negotiations with potential buyers. Some of the sites were closed under state voluntary cleanup programs; others were engaged in remediation under RCRA.
BBJ Group provided a team of outsourced H & S professionals to a manufacturing facility with almost 3,000 employees. BBJ Group conducted a gap analysis of H & S programs at the facility, and developed a Corrective Action / Preventive Action (CAPA) Plan to resolve over two dozen priority items in a period of three to six months. BBJ Group closed out CAPA tasks, and prepared JSAs and PPE assessments for over 75 job roles.
BBJ Group assisted with the remediation of a contaminated manufacturing property. Preliminary estimates to meet site-wide state objectives were several million dollars.Through risk assessment and chemical fate and transport modeling, BBJ Group demonstrated that only some the site required remediation. BBJ Group recommended engineered barriers to address vapor intrusion and worker safety concerns, and also showed that large building dimensions would lead to rapid dissipation of vapor intrusion risks.
