Environmental Investigation Process

As part of the environmental cleanup at Henry Knob, ABB submitted to EPA an Engineering Evaluation/Cost Analysis (EE/CA) report for possible groundwater remedies in March 2012. ABB and EPA recommended extending public water service from Clover. After EPA conducted a public meeting and public comment period on the report and the preferred remedy, ABB met with affected landowners and offered agreements to cover property access, construction and service. After all property owners responded, Clover officials determined that an insufficient number of homeowners accepted, making the extension of a public water system impractical.

In the summer of 2013, ABB and EPA chose residential well treatment systems as the next best remedy. In the fall, ABB presented affected landowners with new agreements to cover the testing, installation and maintenance of individual treatment systems for each property with a dwelling located in the potentially affected area. Company officials contacted each property owner and offered to meet with them to discuss the options. Owners were provided six weeks to consider ABB's offer.

In December 2013, ABB began collecting and analyzing water samples from residential wells of those who accepted the offer. The water tests will be used to design a specific treatment system for each property. ABB's consulting firm, AMEC, will make appointments with each landowner to review the results, and discuss the system design and installation process prior to installation. Installation of the well treatment systems is scheduled to begin in early 2014.
