12. Has a review of all self-monitoring data been conducted(e.g.,DMR,NDMR,NDAR, GW)? ® Yes or❑No
Please summarize any findings resulting from this review: No Monitoring_reports have been submitted since the
system start up,which the contractor said that was an oversight. Duringthe h�pection, it was determined that
sampling pH weekly was not feasible. The permittee and contractor request to sample the pH on a monthly basis.
The system is very small and the contractor can come out monthly for the sampling and collecting the amount of
flow for the month. Based on these concerns,RRO agrees with the permit modification.
13. Are there any permit changes needed in order to address ongoing BIMS violations? ® Yes or❑No
If yes,please explain: Due to the size and flow of the system, collecting pH weekly is excessive. Changing the
