What is the primary objective of stormwater management under DEQ regulations?

• A. To minimize costs by reducing inspector visits.
• B. To maximize land development and accelerated project timelines.
• C. To rely solely on downstream treatment facilities.
• D. To prevent pollutant-laden runoff from reaching waters of the Commonwealth by controlling erosion, sediment, and other pollutants at construction and development sites and through proper BMPs in post-construction.

Answer: (D)

The main idea is protecting water quality by stopping pollutants from entering waters of the Commonwealth at the source. DEQ regulations focus on preventing pollutant-laden runoff by controlling erosion, sediment, and other pollutants at construction and development sites and by applying proper post-construction best management practices (BMPs). This source-control approach is what minimizes the amount of polluted runoff that can reach streams, rivers, and lakes. Why this is the best fit: it aligns with the goal of safeguarding water resources, using erosion and sediment controls during construction and implementing effective BMPs after development to manage stormwater flows and pollutant loads. It treats runoff before it can cause harm, rather than relying on downstream treatment alone or trying to speed up development or cut oversight. Why the other ideas don’t fit: focusing on reducing inspector visits or accelerating development places economic considerations above water protection, which is not the regulatory aim. Relying solely on downstream treatment ignores the need to prevent pollutants from entering waterways in the first place, which is a core part of DEQ’s approach to stormwater management.
