Comments (attach additional pages as necessary)
Contacted Drew Lucas, Site Contact, when arrived on Site. Went into the former manufacturing area
to discuss past and current operations at the facility. The last time the facility distributed residuals was
in 2017. The polishing lagoons were closed and the residual treatment operations shut down. The
lagoons were observed to contain approximately 3-feet of rainwater. According to Mr. Lucas, the
property owner (770 Ventures, LLC) is maintaining the permit as a selling point for the facility. All
equipment has been removed. At the time of the Site visit, the coal handling buildong was being
removed by the D.H. Griffin Company of Greensboro. The facility was in good condition and well
maintained.
Is a follow-up inspection necessary? ❑ Yes ® No
