FILE REVIEW COMMENTS:
19. CVG-Mayflower Vehicle Systems (CVG) was placed into SNC for the first half of 2020 due to the failures to
perfoini/submit flow meter calibrations. KMI was placed into SNC for the first half of 2020 due to nickel and molybdenum
TRC violations.
35. The POTW performed SIU inspections on 12/4/2020 (Cormetech), 9/30/2020 (KMI), and 9/30/2020 (CVG).
39. The POTW has currently contracted Meritech to perform all LTMP analyses.
41a. Cormetch and KMI both contract Pace Analytical Services, Inc. to perform analyses. CVG contracts PAR Laboratories to
perform all analyses.
43b/46. KMI was issued a NOV for molybdenum and nickel limit violations (TRC) that were reported in August 2020. CVG
was issued NOVs for cyanide violations reported in July 2020 and BOD limit violations reported in October 2020.
SUMMARY AND COMMENTS:
The January 2021 eDMR will be revised to correct the units of measurement for zinc (kg/day to ug/L) and remove the high
level mercury value (composite sample) from the same column as the low level mercury value (grab sample). The high level
mercury value can be recorded in the eDMR's comments section.
The records reviewed during the inspection were organized and well maintained. The POTW's Industrial Pretreatment
Program was being properly implemented.
