CESSWI Pollution Prevention and Good Housekeeping 2

Question 1

What is the purpose of a stabilized construction entrance/exit (also called a rock pad or wheel wash) under pollution prevention requirements?

Accepted Answer

To reduce the tracking of mud and sediment onto public roads by construction vehicles

Answer

To create a permeable surface that allows stormwater to infiltrate before leaving the site

Answer

To serve as a secondary containment area for fuel and chemical storage

Answer

To provide a designated area for concrete truck washout operations

Question 2

During a site inspection, you observe vehicle maintenance being performed on bare soil near a drainage channel. Which pollution prevention concern is MOST significant?

Accepted Answer

Potential petroleum product spills contaminating stormwater runoff

Answer

Excessive noise from engine operations near residential areas

Answer

Increased dust generation from vehicle movement on unpaved surfaces

Answer

Risk of workers slipping on wet soil during maintenance activities

Question 3

Under NPDES construction stormwater permits, non-stormwater discharges from a construction site are generally:

Accepted Answer

Prohibited unless specifically authorized in the permit or excluded by regulation

Answer

Always permitted as long as they are less than 100 gallons per day

Answer

Allowed during daylight hours without restriction if diluted to acceptable levels

Answer

Permitted if the contractor notifies the local municipality 48 hours in advance

Question 4

Which of the following construction activities requires a designated washout area to prevent discharge of process water to storm drains?

Accepted Answer

Concrete placement and finishing operations

Answer

Earthmoving with tracked excavators

Answer

Installation of silt fence along perimeter slopes

Answer

Seeding and mulching of disturbed areas

Question 5

A construction site SWPPP requires an inventory of materials that could contribute pollutants to stormwater. Which document is MOST commonly used to identify the hazardous properties of construction chemicals on this inventory?

Accepted Answer

Safety Data Sheet (SDS), formerly known as MSDS

Answer

Environmental Impact Statement (EIS)

Answer

National Pollutant Discharge Elimination System (NPDES) permit application

Answer

Stormwater Pollution Prevention Plan (SWPPP) narrative only

Question 6

Street sweeping of public roads adjacent to a construction site is primarily performed to address which stormwater pollution concern?

Accepted Answer

Remove tracked sediment and debris before it is washed into storm drains by rain

Answer

Reduce vehicle noise from heavy construction truck traffic on roadways

Answer

Improve site visibility for construction personnel operating heavy equipment

Answer

Prevent pavement damage caused by excessive weight of sediment deposits

Question 7

Under good housekeeping practices, construction site dumpsters used for general solid waste should be:

Accepted Answer

Covered or lidded to prevent stormwater from contacting and mobilizing waste materials

Answer

Left uncovered to allow rainwater to drain naturally through the waste

Answer

Positioned directly over storm drain inlets for convenient waste water disposal

Answer

Cleaned weekly by pressure washing, with wash water discharged to the nearest channel
