CESSWI Regulations and Compliance 5

Question 1

Under most state MS4 permits, what minimum level of permanent vegetation cover is typically required before a disturbed area is considered 'finally stabilized' and permit coverage can be terminated?

Accepted Answer

70% uniform vegetative cover

Answer

Most permits define final stabilization as achieving at least 70% uniform perennial vegetative cover, or equivalent stabilization methods.

Question 2

A construction site inspection reveals that the SWPPP has not been updated to reflect a design change that relocated the site's primary sediment basin. Which regulatory provision does this most directly violate?

Accepted Answer

The requirement to maintain the SWPPP as an accurate, current document reflecting actual site conditions

Answer

Permit conditions require that the SWPPP be kept current and reflect actual BMP locations and site conditions throughout construction.

Question 3

Which federal law establishes the framework for protecting wetlands adjacent to construction sites and requires mitigation for unavoidable impacts?

Accepted Answer

The Clean Water Act Section 404 and associated regulatory guidance

Answer

CWA Section 404 requires USACE permits for wetland fill and mandates mitigation (avoid, minimize, compensate) for unavoidable wetland impacts.

Question 4

What is the role of an Erosion and Sediment Control (ESC) plan in the context of regulatory compliance for construction projects?

Accepted Answer

It documents site-specific BMPs for controlling erosion and sediment, often required by local ordinance and incorporated into the SWPPP

Answer

ESC plans document erosion and sediment control measures required by local authorities and are typically incorporated as part of the site's SWPPP.

Question 5

A CESSWI inspector reviewing site records finds that corrective actions identified in a previous inspection were not implemented within the required timeframe. How should this be documented?

Accepted Answer

A new inspection report should note the repeat finding and the failure to correct within the required period

Answer

Repeat or unresolved findings must be documented in subsequent inspection reports as ongoing violations, creating an accurate compliance record.
