EXPERTISE

Closes waste management units per RCRA requirements; obtains risk-based closure for commercial, industrial, and residential properties, thereby facilitating property transaction and development, including "brownfields" and Voluntary Cleanup Program projects; develops cost-effective risk-based closure strategies consistent with proposed future land use.

REPRESENTATIVE EXPERIENCE

Surface Impoundments: Developed engineering specifications for closure of hazardous waste surface impoundments at Texas Gulf Coast chemical manufacturing facility. Managed closure activities and prepared closure reports.

Texas VCP: Demonstrated immobility of residual metals in soil and obtained Certificate of Completion for central Texas machine works facility through the TNRCC Voluntary Cleanup Program.

Lead Stabilization: Performed pilot test to evaluate methodologies for stabilizing lead in soils at tempered glass manufacturing facility, Houston, Texas. Stabilized lead in soils to meet Land Disposal Restriction requirements; excavated stabilized soils. Obtained Certificate of Completion for property through the TNRCC Voluntary Cleanup Program.

Crude Oil: Performed risk assessment at former site of earthen crude oil storage pits. Demonstrated that site met risk-based criteria for industrial land use, and obtained "no-further-action" letter from Railroad Commission of Texas.

Pesticides: Performed site investigation and soil remediation program at site previously occupied by a commercial pest control franchise to satisfy residential land use criteria. Property subsequently developed for residential use.

Natural Attenuation: Conducted site investigation and performed groundwater monitoring to demonstrate effectiveness of natural attenuation at Gulf Coast former industrial waste disposal facility. Obtained Risk Reduction Standard No. 3 closure from TNRCC.
