Dear Mayor Meacham:
On July 22, 2015, Cheng Zhang, Autumn Romanski, and Erin Deck of the Raleigh Regional Office,
Division of Water Resources conducted a Pretreatment Compliance Inspection of the Town of Weldon's
Pretreatment Program. The assistance of Mr. Donald Crowder, Public Utilities Director, and Mr. Bill
Hux, backup ORC of the Wastewater Treatment Plant, was greatly appreciated as it facilitated the
inspection process. The inspection report is attached. Findings during the inspection were as follows:
1. There is one Significant Industrial User(SIUs), which is also a Categorical Industrial User
(CIU). It was noted that the SIU was not in Significant Non-Compliance (SNC) during the two
most recent semi-annual periods.
2. A review of the files containing the pretreatment program elements was conducted. These files
were available and well organized. Please be reminded to submit an update of the Short
Term Monitoring Plan (STMP) or a written statement to indicate that an update is not
needed to the Division by September 1, 2015.
3. The facility will conduct quarterly monitoring in 2016 as specified in the STMP.
4. The pretreatment inspection file review included Roanoke Valley Energy Facility (RVEF)
(Permit No. 0001). The files needed for review were available for inspection, contained the
required elements and in good condition. The SIU experienced one pH violation during the first
semi-annual period of 2015, which was properly addressed by the POTW as required by the
Enforcement Response Plan.
5. During the inspection, Mr. Crowder and Mr. Hux inspected the lone SIU. The inspection was
very thorough. It was evident that Mr. Crowder and Mr. Hux have established good relationship
with the industry representative, broad knowledge of the SIU's pretreatment operation, and great
attention to details.
