STMP File Review Findings
The POTW is sampling as per the approved STMP at the appropriate PQLs.
Industrial User Permit(IUP)File Review
File review for Pittsburgh Glass Works (IWP 001) indicates well organized records and data. The SIU
was not in SNC for the last complete 6-month reporting period.
No Action Items Necessary for the Pretreatment Program
Final Comments
The YVSA industrial pretreatment program is satisfactory. The POTW administrates an adequate
pretreatment program.
Please inform the control authority's Pretreatment Coordinator of our findings by forwarding a copy of this letter
and the enclosed report.
The report should be self-explanatory; however, should you have any questions, please do not hesitate to contact
Mr.McGee at(919) 707-3636, email: keyes.mcgeekdeq.nc.gov.
