All requested files were provided for review. A random comparison of effluent data from January 2021 to eDMR data showed no
discrepancies in reporting. Program elements are up-to-date. Note that the next HWA is due September 30, 2021. The pretreatment
program was found to be well -run and compliant upon this inspection.
OVERALL SUMMARY AND COMMENTS:
Comments: Mr. Grey reached out to Michael Montebello for reclassification of Ingersoll Rand to a non -state -permitted site in
December of 2020. As Ingersoll Rand has reduced flow significantly below the threshold of 25,000 GPD for SIUs and does not produce
any categorical waste, the POTW wishes to continue the Pretreatment Program monitoring Ingersoll-Rand independently. Lowe stated
that he would follow up with Mr. Montebello to find out how such a request might work.
Requirements: None.
Recommendations: None.
NOD: ❑ YES ® NO
NOV: ❑ YES ® NO
QNCR: ❑ YES ® NO
POTW Rating:
