Point sources are permitted; NPS sources are largely managed through programs and BMPs. How are they generally regulated?

• A. Difference in Regulation
• B. Identical Permitting
• C. NPS Permits Only
• D. NPS Unregulated

Answer: (A)

The fundamental idea is that regulation differs by source type. Point sources—discharges coming from a specific, identifiable outlet—are regulated through permits issued under the Clean Water Act (NPDES permits). Operators must obtain authorization for their discharge and meet specific permit conditions. Nonpoint sources—diffuse runoff from land rather than a single pipe—aren’t issued permits. Instead, they’re managed through programs and practices known as best management practices (BMPs) designed to reduce pollution before it reaches water bodies. These BMPs are implemented through state and local programs, voluntary or incentive-based measures, land-use planning, and regulatory guidelines rather than direct permitting. So the general way they’re regulated is a difference in regulation: point sources require permits, while nonpoint sources are guided by programs and BMPs.
