Inspector did not see IU application (04), IU permit approval letter from the Division (08), and no inspection was conducted in
2022 (#35**).
STMP was in order.
NO AUDIT CONDUCTED
OVERALL SUMMARY AND COMMENTS:
Comments: The pretreatment program did not conduct and document an inspection for 2022. The IU permit application, nor a
Division IU permit approval letter was not in files given to inspector for review. The PPS form in PAR was marked 0 for `number
of SIUs NOT inspected by POTW', but no inspection form was in file. Mr. Powers indicated a visit (not inspection) of the SIU was
conducted. PAR was inadequate when submitted in March 2023. Permittee did submit more documentation, however an
allocation table was not submitted.
Requirements: Per 15A NCAC 02H .0905(a): POTW pretreatment program requirements promulgated by the EPA and codified
as 40 CFR 403.8 (f) and (g) are hereby incorporated by reference. 40 CFR 403.8 (f)(2)(v) states Control Authorities are
required to inspect and sample all SIUs a min of once per year. Per 15A NCAC 02H .0916 (c)(4)(A): An allocation table
(AT) listing permit information for all SIUs, including permit limits, permit effective and expirations dates, and a comparison
of total permitted flows and loads with Division approved maximum allowable loadings of the POTW, including flow, on
forms or in a format provided by the Division. The AT shall be updated as permits are issued or renewed, and as permits
are modified where the permitted limits or other AT information is revised;
Recommendations: Issue Notice of Violation for failure to conduct annual SIU inspection. Keep relevant documentation in SIU files (ie:
IU permit application and Division approval letter). Submit allocation table as soon as possible to Division.
