Inspection and site conference with RP and the two SFH RPs that are in progress conducted at 10:30. Turbidity sampling conducted at site and at outfall to Crane Creek, tributary to the Boise River.


-Significant Violation: Illicit stormwater discharge due to runoff polluted with eroded sediment. On February 14th at 10:30 AM, turbidity samples taken in gutter directly below site on Winsome were above the measurement level of 1000 NTU. Crane Creek outfall discharge at 170 NTU. Visible plume in Crane Creek from outfall observed on February 13th at 4:00 PM.


-Significant Violation: Uncontained concrete washout dumped and never cleaned on lot 11, pH of runoff from was 10.8 on digital pH monitor.


-Routine Violation: Unmaintained/damaged BMPs on site. Notification given of retention berm damage on February 4th provided to Responsible Person, no effective corrective actions were implemented. No crew or RP onsite Wednesday PM during heavy rain to monitor and address issues.

-Routine Violation: ESC BMPs are not installed per the approved ESC plan

Notice of Violation issued to site. Over 2 hours and two ESC inspectors investigating the site for this inspection.

RP-GC was on site 2/14 working on BMPs to prevent discharge. There was some muddy runoff flowing under wattles in a few spots adding to the turbidity in the gutter (315 NTU)

RP has contracted with Gatorguard to install a full set of BMPs including a slope drain to convey water down from upper level to the road without causing additional erosion.
