MCCOOK - Officials from the Nebraska Public Power District are warning customers, particularly in the McCook area, that an individual is contacting customers about tree trimming that NPPD is requiring the work to be done and asking for cash payment.

In a statement, NPPD says that when they do tree trimming near power lines, there is no charge to the landowner for the work.

The utility recommends that if approached, they should contact local law enforcement and NPPD.
