A Proposal To Improve Institutional Control Effectiveness Through Better Mapping

Try to read a typical institutional control (IC) and locate its boundaries. We bet you can’t. You will find a complicated legal description referring to metes and bounds, but not a map of the restricted areas that you can actually see and understand. Only licensed surveyors can decipher these legal descriptions, but all the parties […]

Forecasting an Engineering Control or Institutional Control Breach, A Study of Third-party Excavation Activity

Excavations by third-parties are inevitable near any cleanup site. Of concern to cleanup site managers, these unexpected events can breach institutional or engineering controls relied upon in a site’s cleanup remedy. Third-party excavators include utility companies, developers and contractors whose work is not part of the site cleanup process. Terradex completed an analysis of excavation […]

Slowly But Surely: One Call Systems Increasingly Used for Environmental Cleanup Sites

Slowly but surely, often with close involvement of Terradex, the power of one-call helps manage cleanup sites.  In every state, call-before-you-dig or “one call” laws require a phone call (or increasingly an electronic notice) of the planned dig.  State one-call centers route the resulting “excavation tickets” to the people and companies who own or operate underground […]

Terradex Keeps Contaminated Soil Safely Managed

We often think of Institutional Controls (ICs) as prohibiting certain uses – for example, prohibiting groundwater use, prohibiting daycare or school, etc.  But often, and importantly, ICs help make sure that contaminated soil, when excavated,  is managed properly and isn’t, for example, carried away for use as “clean fill.”  For those who deal with ICs, […]

Where is the Water Well? The Competing Interests of Homeland Security and Environmental Health

A strong tension between the environmental health protection and safeguards for homeland security controls whether you will find that water well.  Environmental health protection invites for more  transparency in water well locations […]

Tracing the Evolution of the Phrase “Continuing Obligations”

A new “CERCLA Continuing Obligations” discussion group recently began in Linkedin – actually its a subgroup within the “Environmental Issues in Business Transactions” discussion group that Larry Schnapf manages.  Given this, it seemed right to quickly review how the phrase “continuing obligations” came into being and where its heading. It started with CERCLA’s Brownfield Amendments. […]
