Underground Storage Tank Closures
Duncklee & Dunham has conducted hundreds of projects associated with UST systems in North Carolina, Kentucky, Maryland, West Virginia, Delaware, and Virginia. Mr. Duncklee began conducting UST projects before the UST regulations were effective in December 1988. Mr. Dunham has performed UST services across an area that encompasses most of the southeastern United States. Our senior staff has extensive experience working with staff in the regional offices of NCDENR, which oversee assessment and remediation at UST sites in North Carolina.
Our scope of services has included pre-site assessments and preparation for closure, oversight of UST closures, performance of Limited and Comprehensive Site Assessments, management of free product, preparation of Corrective Action Plans, pilot testing of remediation-system equipment, design of treatment systems, oversight of installation of treatment systems, arrangement of point-of-entry system connections of impacted property owners to public water supply, acquisition of air and NPDES permits associated with remedial-system operations, and as-needed technical support of public participation for corrective action planning and implementation at leaking UST sites.
Duncklee & Dunham has worked with regulated and unregulated USTs that range in size from 280- and 550-gallon tanks common at residences to 10,000- and 20,000-gallon tanks common at commercial at industrial facilities. Commonly, we use geophysical methods to locate USTs when the actual location is unknown.
