Gopher State One Call reminds you to leave any and all utility paint and/or flags in place and clearly visible for at least 16 calendar days after initial application. These flags and paint marks are vital to your safety and the safety of any construction workers excavating in their vicinity. Please do not remove or replace marking flags or wash away paint marks which indicate the presence of underground utilities. This can lead to damages to facilities which can create outages or even extremely dangerous situations. Thank you for your cooperation and contributing to a safer community.
