DWQ-2009-0009 regulates storm water discharges from?

• A. All construction sites that disturb more than 5 acres
• B. All residential development projects
• C. All industrial facilities with ongoing operations
• D. All linear utility projects and construction sites that disturb over 1 acre

Answer: (D)

The key idea is understanding the scope of storm water discharges covered by this regulation. It targets projects that have the potential to generate significant sediment runoff from construction activities and linear utility work, specifically when those activities disturb more than one acre. This threshold aligns with the common construction stormwater permitting framework, designed to ensure erosion and sediment control measures are in place for large-scale sites and for long corridors like roads, pipelines, or electric lines that run across landscapes. Why this option fits best: it includes both linear utility projects and construction sites that exceed the one-acre disturbance threshold, capturing both typical single sites and extended projects that cross multiple parcels along a corridor. Why the other descriptions don’t fit as well: construction sites larger than five acres are covered by broader permitting rules, but the 1-acre threshold is the standard trigger in many programs; focusing only on residential development omits many linear projects and other construction sites, and industrial facilities with ongoing operations are generally regulated under different industrial stormwater programs rather than this specific scope.
