The Missouri Public Service Commission regulates investor-owned electric, steam, natural gas, water and sewer and telephone companies. Its mission is to ensure Missouri consumers have access to safe, reliable and reasonably priced utility service while allowing those utility companies under our jurisdiction an opportunity to earn a reasonable return on their investment. The PSC also regulates manufacturers and retail dealers who sell new and used manufactured homes and modular units. The commission was established in 1913. The PSC is comprised of five commissioners, who are appointed by the governor.

May Is National Safe Digging Month
The month also marks the one year anniversary of 811 -- the national call-before-you-dig number.
If you plan to dig in your own yard or excavate for a commercial
project, Missouri law requires that you notify Missouri One Call
System. Many utility company facilities are located underground and out
of site. Digging carelessly can cause disruption of 
vital utility services and environmental
damage, or even loss of life.
Remember, not all utilities are members of Missouri One Call, so you
will also need to contact those non-members directly before you dig.
Call 8-1-1 or 1-800-DIG-RITE (344-
7483).
Did you know?
• One utility line is unintentionally hit every minute in the U.S.
• 40 percent of all U.S. digging damages result from not calling before digging.
• Utilities are buried only a few inches underground, making them easy to strike even during shallow digging projects.
