2 Verified Questions, Answers, and Explanations
Below are 100 questions with verified answers and detailed explanations, cov-
ering key aspects of stormwater management, SWPPP implementation, and reg-
ulatory compliance relevant to Walmart’s environmental standards.
Question 1: What is the primary purpose of a Stormwater Pollution Prevention
Plan (SWPPP)?
• Answer: To identify potential sources of stormwater pollution
at a construction site and outline Best Management Practices
(BMPs) to reduce pollutants in stormwater discharges.
• Explanation: A SWPPP is a site-specific document required
by the NPDES permit under the Clean Water Act. It ensures
that construction activities do not contaminate nearby water
bodies by controlling sediment, debris, and chemical runoff. It
includes BMPs like silt fences and erosion control blankets to
minimize environmental impact.
Question 2: What federal regulation mandates the development of a SWPPP for
construction sites disturbing one acre or more?
• Answer: The Clean Water Act (CWA).
• Explanation: The CWA, enforced by the EPA, requires con-
struction sites disturbing one acre or more (or smaller sites
part of a larger plan) to obtain an NPDES permit, which in-
cludes developing a SWPPP to manage stormwater runoff and
prevent pollution.
Question 3: What is the primary stormwater pollutant at a construction site?
• Answer: Sediment.
• Explanation: Sediment is the most common pollutant from
construction sites due to soil disturbance from clearing, grad-
ing, and excavation. It can cause stream bank erosion, degrade
aquatic habitats, and increase water treatment costs.
