NPDES STORMWATER EPA: NATIONAL
POLLUTANT DISCHARGE ELIMINATION
SYSTEM, 2025/2026 WITH
CORRECT/ACCURATE ANSWERS
The NPDES Stormwater Program, mandated by the Clean Water Act
and administered by the Environmental Protection Agency (EPA) (and
authorized state agencies), is a comprehensive national program
designed to reduce pollutants in stormwater runoff from non-agricultural
sources before they enter U.S. waterways.
NATIONAL POLLUTANT DISCHARGE
ELIMINATION SYSTEM
Clean Water Act (CWA) of 1972
What Generates Stormwater discharge? - CORRECT-ANSWERS--Discharge
is generated by runoff from land and impervious areas such as paved
streets, parking lots, and building rooftops during rainfall and snow events
that often contain pollutants in quantities that could adversely affect
water quality. >>> precipitation events (rain and snowmelt) that flow over
land or impervious surfaces and do not soak into the ground.
The volume and quality of this runoff are heavily influenced by human
activity and the type of land use, particularly in developed areas where
surfaces prevent natural absorption.
Types of Stormwater Sampling - CORRECT-ANSWERS--Catch Basin
Sampling, Ditch Sampling, Sheet Flow Sampling
,Where to sample - CORRECT-ANSWERS--Pipes (catch basin or outfall),
Open Ditch or a sheet flow. Stormwater discharge is representative of your
wholes sites pollution. Sampling sites must be noted on permit site map
Tools needed for sampling - CORRECT-ANSWERS--Bottle, Gloves, IceBox,
pen, pH paper, and an extension rod.
Things you are sampling for - CORRECT-ANSWERS--Turbidity(cloudiness),
pH, Total Zn, Total Copper, and Oil Sheen
What pollutants usually sampled for - CORRECT-ANSWERS--Stormwater
permits require the development of minimum control measures called
what?: MS4's for stormwater permits and BMPs for industrial stormwater
permits
How does stormwater effect construction sites - CORRECT-ANSWERS--
Stormwater flows over construction sites, picking up pollutants that can
then harm or kill fish/wildlife
NPDES Stormwater Program requires sites of what size sites to obtain
authorization to discharge stormwater? - CORRECT-ANSWERS--One Acre or
larger
What is the focus of the NPDES Stormwater Permits? - CORRECT-
ANSWERS--Stormwater Pollution Prevention Plans
, EPA Construction General Permit (CGP) - CORRECT-ANSWERS--Outlines a
set of provisions that construction operators must follow to comply with
the requirements of the NPDES stormwater regulations.
In California who issues NPDES permits for discharges into federal ocean
water? - CORRECT-ANSWERS—EPA >>> the U.S. Environmental Protection
Agency (EPA) Region 9 is the authority that issues NPDES permits for
discharges into federal ocean waters (waters beyond the state
boundaries, typically more than three miles from shore).
In California what entity handles permits for discharges into non-federal
waters? - CORRECT-ANSWERS—CalEPA >>> the State Water Resources
Control Board (SWRCB) and the nine regional Regional Water Quality
Control Boards (RWQCBs) are the entities authorized by the EPA to issue
permits for discharges into non-federal waters (referred to as "Waters of
the State").
What are the basic requirements of a CGP - CORRECT-ANSWERS--1) Read
entire CGP, 2) Develop a Stormwater Pollution Prevention Plan (SWPPP), 3)
Complete and submit a Notice of Intent (NOI), 4) Install and maintain
erosion and sediment controls throughout the entire construction project,
5) Implement pollution prevention controls, 6) Conduct inspections on the
site based on established timeframe, 7) Take Corrective action to address
any issue with your stormwater controls or discharges, 8) Keep SWPPP up
to date, 9) Comply with any state, requirements, 10) Keep a copy of
permit on site, and 11) Submit a notice of termination once your site is
permanently stabilized or control of site has been transferred to another
operator, 12) Retain records for at least 3 years after NOT
