The Manufactured Gas Plant (MGP) is a facility where gas for lighting and heating homes and businesses was produced as a result of heating coal and from combination of oil and water called "carburetted water-gas" process. The former Brooklyn Borough Gas works began construction of the first generator at the facility in 1908.
On-site disposal of by-products such as coal tar resulting from the operation of the plant has resulted in the contamination of soil, groundwater and Coney Island Creek through the combination of leaks from storage facilities including gas holders and direct discharge to the creek.
In 1951, Brooklyn Borough Gas transformed its gas delivery operations to a natural gas-based system. Between 1952 and 1959, the Brooklyn Borough Gas Company operated the MGP for the purpose of meeting gas supplies during high demands. By 1966, the facility was almost completely decommissioned and demolished.

An expanded consent order has been signed by New York State and KeySpan Energy Delivery that will require the cleanup of contamination at five manufactured gas plant (MGP) sites and seven gas storage sites in Brooklyn and Nassau counties.
