INSPECTOR'S OBSERVATION SUMMARY
According to MSD records, construction approval for the Millipore Sigma Laclede Campus stormwater treatment system
improvements was granted on November 8, 2017 and consists of three biodentention basins. one pretreatment forebay, a permeable
concrete paver patio along with associated private inlets, piping, underdrains, manholes and structures. The fourth 2023 inspection
was performed the morning of November 17, 2023. Stewardship was performed on May 22nd, July 14th, August 28th, September
29th and October 24th. After carefully reviewing each component of the DeKalb Campus stormwater treatment system this day, I'm
confident confirming: based on what was observed, this stormwater treatment sytem appears to be functioning in accordance with its
design intent.

INSPECTOR'S OBSERVATION SUMMARY
According to MSD records, construction approval for the Millipore Sigma Laclede Campus stormwater treatment system
improvements was granted on November 8, 2017 and consists of three biodentention basins. one pretreatment forebay, a permeable
concrete paver patio along with associated private inlets, piping, underdrains, manholes and structures. The fourth 2023 inspection
was performed the morning of November 17, 2023. Stewardship was performed on May 22nd, July 14th, August 28th, September
29th and October 24th. After carefully reviewing each component of the DeKalb Campus stormwater treatment system this day, I'm
confident confirming: based on what was observed, this stormwater treatment sytem appears to be functioning in accordance with its
design intent.

was performed the morning of November 17, 2023. Stewardship was performed on May 22nd, July 14th, August 28th, September
29th and October 24th. After carefully reviewing each component of the DeKalb Campus stormwater treatment system this day, I'm
confident confirming: based on what was observed, this stormwater treatment sytem appears to be functioning in accordance with its
design intent.
