Manufactured Gas Plant Project Moving Along

The former Manufactured Gas Plant in Rockaway Park under remediation by National Grid showed signs of progress last week when the excavation tent was relocated to a new section of the site. The former Manufactured Gas Plant in Rockaway Park, which is currently under remediation of its toxic soil, showed the first signs of significant progress in months when the massive tent was relocated, indicating that a portion of the site is now complete.

The 45-foot-high tent, measuring 188 feet by 194 feet, which was previously located in the southeast corner of the site at Beach 108 Street and Rockaway Freeway, has been relocated and work has begun on the cleanup of the next section of the site, adjacent to the first section.

All eight feet of excavation occurs inside the tent and before the tent is moved to a new location the excavated portion is backfilled with a two and a half foot cap that consists of 18 inches of certified clean sand followed by six inches of gravel and topped off at the surface with six inches of topsoil.

As each portion of the site is finished the tent will be relocated to begin excavation on another area.

The remediation is being conducted by National Grid and began sometime in late April after the tent was originally constructed. The project is slated to last 16 months and according to National Grid officials at a meeting last month, they are on pace to keep the timetable.

It is still unclear, however, what will become of the site after remediation is complete. There are currently an estimated six trucks per hour entering and leaving the site between the hours of 9 a.m. to 3 p.m. Monday through Friday.

The site is continuously monitored for safety with air monitoring, soil gas vapor controls and New York State Department of Environmental Conservation oversight.
