Dear Mr. Wallace, 26 Nov. 2017

Subject: Compost operations

Thank you and Dean for taking time to discuss your compost operations with me. I have been
concerned for sometime that well managed operations get bad press simply because there are
occasional odors detected near an operation. Compost operations are the original recyclers – the
compost process renders a wide variety of organic by-products into valuable soil conditioners and
essential nutrient sources.

I spent several days at the Davie County compost operation. The staff and management were
exceedingly helpful. Staff members and the manager are very knowledgeable regarding the
operations necessary to produce high quality compost. The operations assessed along the compost
production chain are all operated well. That is not to say there are no adverse odors generated,
rather it is to state that when:

1. Products are received and processed staff does everything possible to manage and control odor at
or near the mix pit and during the initial stages of the composting process, and

2. Odor is detected, it is managed appropriately

The Wallace Farm compost operation in Davie County generates very high quality compost. Staff
manages the feedstocks appropriately. My summary report is attached.

Respectfully Submitted,

A. R. Rubin, Professor Emeritus
