What is the primary purpose of a Stormwater Pollution Prevention Plan (SWPPP)?
Answer: Identify potential pollutant sources and BMPs to prevent stormwater contamination
A SWPPP identifies potential pollutant sources at a site and describes best management practices (BMPs) that will be implemented to prevent or reduce stormwater contamination.
Which hydrological equation balances inputs, outputs, and storage changes in a watershed over a given period?
Answer: Water Budget (Hydrologic Balance)
The water budget or hydrologic balance equation (P = ET + R + ΔS) states that precipitation equals evapotranspiration plus runoff plus the change in storage.
What does 'hydraulic conductivity' measure in groundwater science?
Answer: The ease with which water flows through a porous medium
Hydraulic conductivity (K) quantifies how easily water moves through a porous medium, reflecting both the properties of the medium and the fluid.
Under Section 401 of the Clean Water Act, which entity must provide a water quality certification before a federal permit is issued for activities affecting water quality?
Answer: State environmental agency
Section 401 requires the applicant to obtain water quality certification from the state in which the discharge will originate before a federal license or permit is issued.
What is the Rational Method used for in stormwater engineering?
Answer: Calculating peak runoff from small drainage areas
The Rational Method (Q = CiA) is used to estimate peak stormwater runoff from small urban drainage areas based on rainfall intensity, area, and a runoff coefficient.
Which federal program under the Safe Drinking Water Act requires EPA to set maximum contaminant levels (MCLs) for drinking water?
Answer: National Primary Drinking Water Regulations
The National Primary Drinking Water Regulations (NPDWRs) establish legally enforceable MCLs or treatment technique requirements for contaminants that pose health risks in public water systems.
