Inspection Summary:
The inspection was conducted by Beverly Price of the Asheville Regional Office; Gregg Padgett and Chris Bortnick assisted.
This inspection was performed in conjunction with the NPDES inspection (NC0041696)conducted by Linda Wiggs (ARO).
The Class A facility consists of a concrete pad for composting with a covered area for the finished product. Residuals are
mixed with wood chips/leaves/mulch and placed in aerated static piles. Compost is monitored for time/temperature. Once
all time/temperature requirements have been met, the pile is broken down and moved to the back of the compost pad where
it is sampled for nutrients/metals/TCLP and fecal coliform. All leachate drains back to the head of the WWTP. The
concrete pad is bermed to prevent compost/wood chips from migrating off the pad. A small amount of wood chips was
observed on the stormwater grate located on the northwest side of the access road. It is recommended that the berm height
be increased or more frequent sweeping/cleaning of the concrete pad to ensure no material is lost to the stormdrains.
The NC0041696 report will be sent separately.
