, Q1. A utility contractor is planning to excavate in a public right-of-way in Milwaukee.
According to Wisconsin's One-Call law (Wis. Stat. § 182.0175), which of the following
actions is mandatory before beginning excavation?
A. Submit a detailed excavation plan to the local municipality for approval.
B. Contact the Wisconsin One-Call system (Diggers Hotline) at least 3 working days
prior to excavation.
C. Obtain a permit from the Wisconsin Department of Transportation (WisDOT) for
any excavation in a public right-of-way.
D. Notify all affected utility owners by certified mail at least 48 hours in advance.
Correct Answer: B. Contact the Wisconsin One-Call system (Diggers Hotline) at least
3 working days prior to excavation.
Rationale: Wisconsin's One-Call law requires excavators to notify Diggers Hotline at
least 3 working days (not including weekends or legal holidays) before starting
excavation. This allows utility owners to locate and mark their facilities. Option A is not a
statutory requirement; Option C is only needed for state highways; Option D is not the
mandated method.
Why Wrong:
A - Municipal approval is not a substitute for the One-Call notice; it is a separate local
permit requirement.
C - WisDOT permits apply only to state highway rights-of-way, not all public
rights-of-way.
D - Certified mail notice is not the prescribed method; the One-Call system is the
exclusive notification mechanism.
Reference: Wis. Stat. § 182.0175; Wisconsin Administrative Code SPS 328.02
Q2. During trenching operations, a contractor encounters 5 feet of Type B soil with
no protective system in place. Under OSHA 29 CFR 1926 Subpart P, which of the
following is the most immediate compliance requirement?
A. Slope the trench walls at a 1:1 angle (45 degrees) or provide a protective system.
B. Install a trench box only if workers are inside the trench.
C. Conduct daily visual inspections by a competent person before each shift.
D. Immediately stop all work and notify OSHA within 24 hours.
Correct Answer: A. Slope the trench walls at a 1:1 angle (45 degrees) or provide a
protective system.
Rationale: OSHA requires protective systems for trenches 5 feet or deeper, unless the
trench is entirely in stable rock. For Type B soil, the maximum allowable slope is 1:1 (45°).
A trench box is one option but must be used regardless of whether workers are inside;
daily inspections are required but do not replace the need for a protective system;
stopping work and notifying OSHA is not required unless a fatality or serious incident
occurs.
