C. 2 acres
D. 5 acres
ANSWER: B. 1 acre
RATIONALE: The CGP applies to construction activities that disturb one

plan of development. Any clearing, grading, grubbing, or excavation
resulting in land disturbance of one acre or greater requires permit
coverage.
WRONG ANSWERS:
- A. 0.5 acre: This threshold applies to certain other environmental
permits, not the California CGP.
- C. 2 acres: While some activities disturb 2 acres, the permit
threshold remains 1 acre.
- D. 5 acres: Not the threshold; sites as small as 1 acre require
coverage.

D. California Environmental Protection Agency
ANSWER: C. State Water Resources Control Board (SWRCB)
RATIONALE: The SWRCB, together with the nine Regional Water Quality
Control Boards, administers the CGP for construction stormwater in
California. The 2022 CGP (Order No. 2022-0057-DWQ, NPDES No. CAS000002)
was adopted on September 8, 2022, and became effective September 1,
2023. A two-year regulatory transition period followed, ending September

, and flood control, not stormwater permitting.
- B. California Air Resources Board: Regulates air quality.
- D. CalEPA: The umbrella agency; SWRCB is the specific permitting
authority.
Q4. When does the Construction General Permit (CGP) apply?
A. Construction on any size lot
B. Only projects over 5 acres
C. Any construction or demolition disturbing one acre or more, or
smaller sites part of a larger common plan
D. Only projects near water bodies
ANSWER: C. Any construction or demolition disturbing one acre or more,
or smaller sites part of a larger common plan
RATIONALE: The CGP applies to any construction or demolition activity
that disturbs one acre or more of land surface, or projects that are
part of a common plan of development or sale that disturbs more than
one acre. Linear underground projects (LUPs) disturbing one or more
acres also require coverage.
WRONG ANSWERS:
- A. Any size lot: The threshold is one acre; smaller individual lots
may qualify if part of a larger plan.
- B. Over 5 acres: The threshold is one acre, not five.
- D. Near water bodies: The CGP applies regardless of proximity to
water bodies, though risk level is affected by receiving water
proximity.
Q5. Which of the following activities is regulated under the CGP?
A. Routine maintenance to maintain original line and grade,
hydraulic capacity, or original purpose of the facility
B. Disturbances to land surfaces solely related to agricultural
operations
3
, C. Clearing and grading 2 acres of land for residential development
D. Discharges of storm water from areas on tribal lands
ANSWER: C. Clearing and grading 2 acres of land for residential
development
RATIONALE: Clearing and grading that disturbs one or more acres of
land is a regulated activity under the CGP. Residential development
is a typical covered activity.
WRONG ANSWERS:
- A. Routine maintenance: Activities to maintain original line and
grade, hydraulic capacity, or original purpose of a facility are
typically exempt.
- B. Agricultural operations: Disturbances solely related to
agricultural operations are typically exempt.
- D. Tribal lands: Discharges from tribal lands are regulated under
separate permitting frameworks.
Q6. TRUE OR FALSE: For a Linear Underground Project (LUP) crossing
multiple properties, the utility company or public/private agency that
owns or operates the LUP project is responsible for obtaining CGP
coverage.
A. True
B. False
ANSWER: A. True
RATIONALE: For linear underground projects that span multiple
properties, the entity that owns or operates the LUP project is
responsible for obtaining permit coverage. This ensures clear
accountability regardless of how many properties the project crosses.
Q7. The Legally Responsible Person (LRP) must receive which type of
communication from the QSP?
