The Fulton Municipal Gas Company was incorporated in March 1879 and the Fulton Manufactured Gas Plant is first shown on maps in 1886. The MGP gas production facilities were located on what is now 270 Nevins Street and consisted of coal gas production facilities including a retort house, an engine room, condenser rooms and a gasoline house. Gas storage and purification facilities – including two gas holders, a governor house, purifying houses and a lime house – were located to the southeast across Nevins Street on 37 Sackett Street and 560 Degraw Street. A hydrogen tank, a purge tank and naphtha tanks were located at 225 Nevins Street.  By late 1888, a gas holder (the large tank in which gas was stored before being distributed) was constructed at 191 3d Avenue

In 1895, the Fulton Municipal Gas Company and others merged to form the Brooklyn Union Gas Company, a predecessor to KeySpan and now National Grid. A 1904 Sanborn map indicates that the MGP was referred to as the Brooklyn Union Gas Fulton Municipal Branch. According to 1904 Sanborn maps, the gas production facilities at 270 Nevins Street remained relatively unchanged with the exception of the addition of a circular oil storage tank, underground oil tanks, and an aboveground tar separator. Two circular oil tanks and additional underground gas oil tanks were noted at 225 Nevins Street. By 1915, the MGP appears to have converted to water gas production as evidenced by the addition of generators and conversion of the retort house to a generator house at 270 Nevins Street. An additional oil storage tank was noted on the 225 Nevins Street property.

The Fulton Former MGP ceased operation prior to 1938. The MGP structures were dismantled and vacant lots are shown in the 1938 Sanborn map.  The Fulton MGP was subdivided and redeveloped for commercial, industrial, and recreational uses. These parcels are all currently owned and/or used by third parties unrelated to National Grid.

In April 2007, the NYSDEC, independent of KeySpan (now National Grid), undertook a Site Characterization Investigation to determine if contamination associated with the former MGP operations remained in soils. Because access to the privately owned properties was not available, the investigation took place only within Thomas Greene Park and the nearby public streets.  The Site Characterization Report noted that “coal tar contamination was not found at or near the surface of the ground, but was found in soil borings in the subsurface soils at depths below 7 feet. Soils less than 7 feet below ground surface were not found to contain tar contamination.  Because of these depths, human exposure to coal tar contaminants by routine users of the park, workers involved in park operations or people in the surrounding neighborhood is not expected. Exposures to construction or maintenance staff could occur during intrusive subsurface work that reaches to depths.”
