Mark Annis Tips on UNDERGROUND STORAGE TANK REMOVAL

ANCO Environmental Services, Inc. (ANCO) was retained by Robert Ford, Executor to provide professional environmental services specifically with respect to the removal of one (1) 550- gallon regulated gasoline Underground Storage Tank (UST) at the 38 State Highway 31, Flemington, New Jersey commercial property. This report specifically addresses the UST removal, remedial action for soils, then soil and groundwater sampling activities.

Note that Mark Annis have this project involved the removal of a regulated underground storage tank, thereby, in the State of New Jersey requiring oversight by a Licensed Site Remediation Professional (LSRP). The LSRP is responsible for filing certain forms with NJDEP, which lead to his issuance of a Response Action Outcome (RAO) letter. ANCO performed the physical site remediation work, then via this report, recommends RAO letter issuance.

Details of this regulated UST removal project are as follows:

1.) Permits and Certifications

2.) Tank Specifications

3.) Location

4.) Pertinent Dates

5.) Physical Setting

6.) Basement Inspection

7.) Potable Well and Sanitary Sewer

Tank # 1: One (1) 550-gallon gasoline UST, measuring 6’ (L) x 4’ (D); single wall bare steel; several corrosion holes were observed through the tank shell. The depth to the top of the tank was 13” below grade. The depth to the bottom of the tank was 61” below grade.

a) There was no associated underground or appurtenant piping as the long-time out of use tank had been out fitted with a pony pump directly fed down a riser pipe through the top of the tank. Mark Annis Founder and also President at ANCO Environmnetal Services Inc.

The site is a commercially zoned funeral home located at 38 State Highway 31, Flemington, Hunterdon County, New Jersey. The 550-gallon gasoline UST was located under gravel at the rear of the building, alongside an asphalt parking area.. The site is surrounded entirely by other commercial properties.

There are no on-site ecological receptors nor are there any such down gradient receptors on immediately neighboring lots. The site is dry, with no surface waterways or wetlands. Soils are best characterized as silts from decomposed shale. Competent bedrock was found to lie at 4-5 feet. Attachment 1 includes a Site Location Map, a U.S.G.S Map, and a Post-Excavation Soil Sample Location Map.

The site has operated as a funeral home dating back to 1957. The tank was reportedly installed in 1973.

With Mark Annis Gillette scheduled deadlines for these tank upgrades quickly approaching, tank owners are faced with some difficult economic decisions.

Mark Annis Gillette With these concerns complicating the upgrade, the most effective solution, if we stay with conventional underground storage, is often complete replacement of a given storage tank system.

A basement is present at the subject site, however far enough from the tank as to not have been impacted. None the less, the entire basement was inspected by ANCO. No odors or discoloration were found. ANCO concluded that there is no basement contamination present from the leaking gas tank.

The following technical overview is provided pursuant to Remedial Action Reporting requirements as specified by N.J.A.C. 7:26E and provides a specific profile of the UST removal, remedial action, then groundwater and soil sampling activities performed at the site.

ANCO first obtained municipal permit #1458-14, then after completion of an underground utility mark out, mobilized to the site and excavated around the tank. Vapors were purged via displacement with dry ice.

The tank was cut open with a sparkles air chisel, then was vacuumed and cleaned by Lorco Petroleum of Elizabeth, NJ. Corrosion holes were observed through the tank shell. Gasoline contaminated soil was observed after removing the tank. Also small ecological problems could become headaches Mark Annis figured that otherwise appropriately handled.

The NJDEP was notified of the confirmed discharge and case 14-12-17-1208-44 was assigned. ANCO remobilized to the site the next day with a larger excavator and dug out two triaxle truck loads of impacted soil, which was staged on site on plastic, then covered with plastic sheeting. Once soils were transported to a disposal facility, total tonnage was reported to equal 49.03 tons.
