Site Location
The Nebo-Hemphill Unnamed Production Oil Salvage abandoned oil production facility (EPA ID 30-E-1061) was referred to the United States Environmental Protection Agency (EPA) on July17, 2008 by the State of Louisiana to be considered for Oil Pollution Act (OPA) response actions. This facility is located in Nebo-Hemphill Oil and Gas Field (Field ID 7040), approximately 6.6 miles south of Jena, in Section 038, Township 07 North, Range 03 East of LaSalle Parish, Louisiana. The facility is accessed from the west via Deville Hill Road off of Louisiana Highway (LA Hwy) 127.
Site Description
The facility consists of six above-ground storage tanks (AST) and one secondary containment area (CONT) located at one potential spill source (Source 1). Louisiana Department of Natural Resources (LDNR) records indicate that the facility received salvaged oil from area oil production facilities, but was not associated with a specific well or lease.
Source 1 consists of three bolted-steel tanks, identified as AST1, AST2, and AST3, and two welded-steel horizontal tanks, identified as AST4 and AST5, located in an eroded, breached, earthen-bermed, secondary containment area, identified as CONT1, located at Latitude 31.590889 North and Longitude 92.139750 West. One bolted-steel tank, identified as AST6, is located 150 feet east of CONT1. AST6 has no descernible secondary containment. OA1, a 5-foot by 15-foot area of oil-saturated soil, is located below the west side of AST6.
Based on gauging, and surface soil core and field observations, the following volumes of oil waste were estimated to be present at Source 1 of the facility. AST1 through AST6 contain a total of 347.3 barrels (bbl) of oil and oil emulsion and 25.7 bbl of oily produced water. In addition, CONT1 has 63.9 bbl of pooled oil and CONT1 and OA1 have 46.4 cubic yards (yd3) of oil-saturated soil.
Previous Actions
The EPA Region 6 Federal On-Scene Coordinator (FOSC) conducted a reconnaissance of the facility on July 19, 2008 to determine if this facility meets the revised Region 6 substantial threat criteria. The FOSC has determined from his reconnaissance that Source 1 of this facility meets the criteria for proceeding with a Site Assessment (SA) (See. Minimum Threshold Checklist attached at the website for this facility).
On April 28, 2009 EPA On-Scene Coordinator (OSC) Mark Hayes, Emergency Rapid Response Services (ERRS), and the U.S. Army Corps of Engineers (USACE) visited the facility for a site-walk in preparation for the removal action.
ERRS is scheduled to mobilize on-site and begin the removal action on May 4, 2009. The removal action will encompass the emptying of contents, dismantling, cleaning, and recycling of all storage tanks. Any remaining oil-impacted soil, if minimal, will be blended with clean soil and landfarmed on site.
