Is there a way to screen for MLP's that issue 1099's? IE: that are C Corps?

I am interested in finding MLP's that issue 1099 tax forms rather than K-1's.  Is there an easy way to screen for that, or to find those that use a C corp structure?  The logic is to simplify things at tax time.  I am having problems finding this info per company.  Thanks for any ideas on this.
