How often does the CGP permit require inspections to be conducted?

The correct answer involves a specific requirement outlined in the Construction General Permit (CGP) regarding the frequency of inspections at construction sites. Specifically, the CGP stipulates that inspections must be conducted weekly, and additionally, within 24 hours following rainfall events that result in a half-inch of accumulation or more. This dual approach of routine inspections and response to significant rainfall helps ensure that erosion and sediment control measures are effective and that water quality is not compromised.

By demanding inspections after specific rainfall amounts, the CGP addresses the need to promptly identify and rectify potential erosion or sedimentation issues that can arise from heavy rain, thereby protecting nearby water bodies from contamination. The weekly inspections serve a preventive purpose, allowing for regular assessment of the site's stabilization efforts and the effectiveness of implemented controls.

This timetable for inspections is crucial for ensuring compliance with environmental regulations, as it emphasizes proactive management of stormwater and sediment control technologies during construction activities, thereby minimizing their environmental impact.
