(a) Owned or operated by the federal

district under state law such as a sewer district, flood control district or

[Comment: What constitutes a municipal separate storm sewer
system is often misinterpreted and misunderstood. The term does not solely
refer to municipally owned storm sewer systems, but rather is a term of art
with a much broader application that can include, in addition to local
jurisdictions, state and federal facilities, public universities, local sewer
districts, public hospitals, federal installations, military bases and prisons.
The municipal separate storm sewer system is not just a system of underground
pipes -it can include roads with drainage systems, gutters and ditches.]
