longislandmike, this is another example of NEWSDAY mistaking the community name in a place's mailing address for the community in which that place is located:
In the first paragraph, the article states, "The price tag for modernizing the giant E.F. Barrett power plant in Island Park ... "
The E.F. Barrett power plant is in Barnum Island ("Island Park, NY 11558" mailing address).
In other words, if you want to send a letter to the E.F. Barrett power plant, you would address this letter to "Island Park, NY 11558"; however, if you want to actually go to the E.F. Barrett power plant, you would go to Barnum Island.
It is important to understand that Barnum Island is one of those many villages and hamlets on Long Island where none of the places in the community have the hamlet name in their mailing address.
For those who may not be familiar with Barnum Island:
Barnum Island is a hamlet (an unincorporated area) in the southwest part of the Town of Hempstead, in the southwest part of Nassau County.
Beginning on the north and moving in a clockwise direction, the Hamlet of Barnum Island in the Town of Hempstead is bordered on the north by Simonson Channel and the Hamlet of Oceanside; on the east by the East Channel; on the south by Reynolds Channel; and, on the west by the Village of Island Park.
