1Under the EPA NPDES Construction General Permit (CGP), construction stormwater coverage is generally required when earth-disturbing activities will affect which minimum area, including a larger common plan of development?
A.5,000 square feet
B.1 acre
C.5 acres
D.10 acres
Explanation: The federal NPDES Construction General Permit applies to construction that disturbs 1 acre or more of land, or less than 1 acre if the work is part of a larger common plan of development or sale that will ultimately disturb 1 acre or more. GF Core stormwater items expect contractors to recognize that threshold and to obtain coverage before clearing and grading a tank, pipeline, or substation yard that meets it.
2What is the primary purpose of a Stormwater Pollution Prevention Plan (SWPPP) on a New Mexico GF-8 transmission-line, tank, or substation site?
A.Identify pollutant sources and the erosion, sediment, and good-housekeeping controls that will keep construction stormwater from leaving the site dirty
B.Replace the need for a construction-stormwater permit once the plan is kept in the job trailer
C.Set the hydrostatic-test pressure for API 650 tanks
D.Serve as the only required excavation-safety plan under OSHA 1926 Subpart P
Explanation: A SWPPP is the site-specific document that describes the project, receiving waters, pollutant sources, and the BMPs (silt fence, inlet protection, stabilized exits, concrete washout, spill control) that will be installed, inspected, and maintained. EPA’s construction-stormwater program requires the plan to be developed and implemented as a condition of CGP coverage; it does not replace the permit itself.
3For a new construction site seeking coverage under the EPA Construction General Permit, when must the operator typically submit a Notice of Intent (NOI) relative to the start of earth-disturbing work?
A.No later than 24 hours after the first rain event
B.On the same calendar day grading begins
C.At least 14 calendar days before earth-disturbing activities commence
D.Only after final vegetative stabilization is complete
Explanation: EPA’s CGP requires the operator of a new site to file a complete electronic NOI at least 14 calendar days before commencing earth-disturbing activities. Coverage is then generally effective 14 days after EPA acknowledges a complete NOI, unless EPA delays or denies authorization. Starting a tank-pad or pipeline right-of-way before that waiting period expires is a common compliance failure.
4Which perimeter BMP is installed downslope of a disturbed tank-pad or pipeline right-of-way primarily to pond sheet flow long enough for sediment to settle before water leaves the site?
A.A straw-bale check dam placed in a concentrated channel
B.A properly trenched and backfilled silt fence
C.A concrete washout pit at the batch-truck chute
D.A rock construction-exit pad at the public-road interface
Explanation: A silt fence is a temporary geotextile perimeter control for sheet flow. The fabric is trenched in, backfilled, and supported so runoff ponds and drops sediment rather than flowing under or around the fence. Check dams, washouts, and rock exits are important BMPs, but they address concentrated flow, concrete waste, and track-out—not downslope sheet-flow interception.
5What is the main purpose of a stabilized construction entrance or exit at a GF-8 yard or pipeline crossing of a paved public road?
A.Increase the compacted density of the subgrade under the first asphalt lift
B.Provide the only acceptable means of trench egress under OSHA 1926.651
C.Substitute for inlet protection at curb inlets
D.Remove sediment from vehicle tires so it is not tracked onto the public roadway
Explanation: A rock (or equivalent) stabilized construction exit is a good-housekeeping BMP that knocks mud off tires before trucks enter the public road. Track-out is a frequent CGP violation. The pad does not replace trench ladders, inlet inserts, or pavement-density requirements.
6Under the EPA Construction General Permit, final vegetative stabilization is generally achieved when uniform perennial vegetation provides at least which portion of the cover that native vegetation provided on local undisturbed ground?
A.30 percent
B.50 percent
C.70 percent
D.100 percent of the original plant species list
Explanation: EPA’s CGP defines final vegetative stabilization as uniform, perennial vegetation that provides 70 percent or more of the cover that was provided by vegetation native to local undisturbed areas, without large bare patches. If native cover was only 50 percent, the target is 70 percent of that 50 percent (35 percent cover). Arid and semi-arid New Mexico sites may use a three-year establishment path plus temporary non-vegetative cover.
7On a portion of a pipeline right-of-way where earth-disturbing work has temporarily ceased, the EPA CGP generally requires the operator to initiate temporary stabilization by which time?
A.Immediately upon determining that disturbance has stopped and will not resume for 14 or more days, and complete it within the permit’s stabilization deadline
B.Only after the next 0.25-inch storm
C.Within 90 days of the last equipment move, regardless of inactivity
D.Never, if a silt fence remains in place
Explanation: The CGP requires operators to initiate stabilization immediately when earth-disturbing activities have permanently ceased, or have temporarily ceased and will not resume for 14 or more calendar days, on any portion of the site. Completion deadlines are typically 14 days (or 7 days for larger unphased or sensitive-water sites). Perimeter silt fence alone does not satisfy the temporary-stabilization duty on idle soil.
8Why must storm-drain inlets that receive runoff from an active tank-farm or substation-yard grading operation be protected before soil is stripped?
A.Inlet bags replace the need for a SWPPP on sites larger than 1 acre
B.Unprotected inlets convey sediment directly into the municipal or roadside drainage system and receiving waters
C.Inlet protection is required only after the first silt-fence failure
D.OSHA 1926 requires inlet inserts as the primary cave-in protective system
Explanation: Curb and drop inlets are direct pathways from the construction pad to waters of the United States or to a municipal separate storm-sewer system. The CGP and EPA stormwater-management guidance require inlet protection (filter bags, wattles, or equivalent) so sediment is captured before it enters the drain. Protection is a planned BMP, not a repair after the first failure.
9Where should leftover concrete and concrete-truck wash water from a tank-ring-wall or substation-foundation pour be discharged?
A.Into the nearest storm inlet after the pour is finished
B.Onto bare soil upslope of the silt fence so the cement can neutralize
C.Into the open pipeline trench to improve bedding cementation
D.Into a designated, contained concrete-washout facility that prevents the waste from reaching storm drains or waters
Explanation: Concrete wash water is highly alkaline and is a construction-stormwater pollutant. EPA CGP good-housekeeping rules require a designated, leak-resistant washout so leftover concrete and chute rinse stay out of storm drains, trenches, and waters. Dumping into inlets, onto unprotected soil, or into a pipeline ditch is a permit and water-quality violation.
10Under typical EPA Construction General Permit inspection options for a non-sensitive-water site, a 0.25-inch storm generally requires the operator to inspect BMPs within which time?
A.7 calendar days after the rain stops, regardless of the selected inspection schedule
B.Only at the next weekly safety meeting
C.Within 24 hours of the storm when the operator is using the 14-day-plus-storm inspection option
D.Only if a Notice of Violation has already been issued
Explanation: EPA’s CGP lets many sites inspect either at least once every 7 calendar days, or once every 14 calendar days and within 24 hours of a storm of 0.25 inch or more (or a snowmelt discharge). Sensitive-water sites are more stringent. Contractors who choose the 14-day option must still respond within 24 hours of a qualifying rain. Inspections are a permit duty, not a response to enforcement.
