IV. ADDITIONAL REGIONAL STAFF REVIEW ITEMS
145B49E225C94EA._.
On July 29, 2020, WSRO staff made a site visit to the subject facility for an inspection and review associated with the
application for permit renewal. Accompanying staff on the visit was Mr. Daniel Davis, Superintendent & Back -Up ORC
and Mr. Randy (Rabbit) Homey, ORC. Below is a summary of items noted during the visit, one which requires
additional information be provided.
While onsite, the Permittee indicated that they forgot to include both of their WWTPs on the RSC form. They
left "Grassy Gap Creek WWTP" off the application. Reportedly there are no changes at the facility or in the
proposed annual dry tonnage. Need to request a revised RSC form and any information related to this
existing source not listed; also, the proposed column on the form needs to read the same as current if no
changes. They left the proposed column blank; it should list the same values as current if no changes are
requested.
2. The subject facility has not produced compost within the last two permit cycles. They have been hauling 100%
of sludge produced to landfill. Landfill hauling receipts for years 2018, 2019, and thus far in 2020 were reviewed
and appear to be complete.
The previous ORCs (now retired) reportedly had some issues with meeting 503 temperature requirements and
therefore stopped trying to make compost. The last attempts at making compost was believed to be—2005-2006
timeframe. Reported that all sludge has been hauled to the landfill since that time.
Recently upgrades have been made at the WWTP with new equipment added to the treatment process. In
addition, new ORCs are now running the operation and they have interest in trying to produce compost with
the sludge produced from the updated WWTP. They discussed potentially trying several different compost
methods to meet Pathogen & Vector Attraction Reduction requirements (windrow method, within vessel
method and aerated static piles method), to see which works best for this facility.
