Thank You! ------- ------- AGRICULTURE STREET LANDFILl LOUISIANA EPA ID# LAD98105699 EPA REGION 6 CONGRESSIONAL DISTRICT 02 Orleans Parish New Orleans Site Description Location: Population: The site is located in New Orleans, Orleans Parish, Louisiana. It is approximately three miles south of Lake Pontchartrain and 2.5 to 3.0 miles north-northeast of the Vieux Carre and the Central Business District. The approximate geographic coordinates for the center of the site are 29°59'20" north latitude and 90°02'31" west longitude. The site is bounded on the north by Higgins Road and on the east from Clouet Street (to the south) to Montegut Street (to the north). On the south and west, the site runs along the Southern Railroad right-of-way. The Peoples Avenue and Florida Avenue canals are located west and south of the site, respectively. The 1990 Census identifies 374 residential units (some 1,000 people) on site. The community is predominately African American. Setting: A 100 acre former City disposal area that has been partially redeveloped. 47 acres of the site has private and public housing, the Press Park Community Center, a recreation center, retail businesses, and the Moton Elementary school. The remainder of the site is undeveloped and covered by dense vegetation. Hydrology: The Peoples Avenue canal is to the west and the Florida Avenue canal is to the south. Both receive storm water runoff from the site. Canal water is pumped into Industrial Canal which then discharges into Lake Pontchartrain. A shallow aquifer (that is not a drinking water source) that underlies the site is encountered between 2 and 9 feet below land surface. November 29, 1995 ------- Wastes and Volumes When in operation, the disposal area accepted municipal garbage, construction debris, incinerator and open burning ash. This type of material ranges in depth from 2 to more than 32.5 feet beneath the 100 acre site. Site Assessment and Ranking NPL LISTING HISTORY Site HRS Score: 50,00^ Proposed Date: 8/23/94 Final Date: 12/16/94 NPL Update: No. 13 Site Map and Diagram The Remediation Process SH* History. 1910 to 1957- used as a municipal landfill 1958- The incinerator on site was decommissioned. November 28, 1995 AGRICULTURE STREET LANDFILL ------- * *$! :» 1965- Landfill reopened to receive debris created by Hurricane Betsy; open burning of waste continued for 6 to 7 months, after which the area was covered with ash from city incinerators and compacted with bulldozers. 1977 to 1986- the northern portion of site was re-developed to support housing (390 properties are on the site of the old landfill), small businesses, and the Moton Elementary school. The residential properties received a relatively thin (often 6 inches or less) covering of soil; the Moton School was built upon several feet of clean fill. 1986- EPA completed a site investigation. Under the 'old' HRS ranking system (which excluded ingestion) the site did not qualify for placement on the National Priorities List (NPL). 1993- On May 4 community leaders from the Moton Elementary school area filed a complaint with the Gulf Coast Tenants Organization and requested EPA to re-evaluate the site. In September EPA collected additional samples for use in the revised HRS model (that reflects ingestion). 1994- EPA initiated an accelerated investigation integrated with Removal Actions. Fieldwork was completed in May 1994 including the erection of a fence around the undeveloped area and removal of highly contaminated soils at a children's play area. The site was proposed to the NPL August 23, 1994. Due to community concerns created by the Superfund listing, the school board announced on August 24, the Moton would not open and that students would be bussed to a different school. The site was formally added to the NPL on December 16,1994. Health Considerations: MOTQN SCHOOL: No health or environmental problems detected; the school built on top of 3 to 5 feet of clean fill. SHALLOW GROUND WATER: found to be contaminated with elevated levels of metals. However, this aquifer is not useable by humans and was not found affect surface water. RESIDENTIAL AREAS - SOILS: * Current Surface Contamination - Marginal human health risk: 1.3 X IP"4 lifetime cancer risk (all contaminants of concern); 6.1% children with projected risk (Pb concentrations 500 to 1,000 ppm). * Future Surface Contamination - If landfill materials below the top foot of soils were exposed due to human activity, health risks would increase to: 5.0 X IP"4 lifetime cancer risk (all contaminants of concern); 63.8% children with projected risk (Pb concentrations 1,000 to 4,000 ppm). AGRICULTURE STREET LANDFILL November 28, 1995 ------- UNDEVELOPED PROPERTY SOILS; * Current Surface Contamination - Currently contamination levels are high (e.g. 1,000 to 4,000 ppm lead, but there is no routine exposure of people. * Future Surface Contamination - City has zoned tracts "residential." Other Environmental Risks: The site is an urban setting; there are minimal ecological impacts.

Site has had numerous owners, the first of which was the Bodeau Lumber Co., which began operations in 1901. Louisiana Creosoting Co. acquired 22 acres of the property in 1922 and then resold the parcel of land to American Creosote Works of Louisiana, Inc. in 1938. In 1950, the entire property, along with 12 additional acres, was sold to American Creosote, which was later bought out by Dickson Lumber Co. in 1977. The property was seized by the city for taxes after Dickson declared bankruptcy. Wood treatment operations were taken over by Stallworth Timber in 1980 which then abandoned the site in 1985. Sources of contamination at the site include: five unlined pits used for the disposal of wastes generated by the wood-treating process, storage areas containing creosote and treated and untreated wood, and the plant at which the wood-treating operations took place. Contamination also was caused by on-site drainage ditches which received surface water run-off from the facility. April - May 1988, EPA Emergency Response Branch conducted emergency removal to prevent oils and sludges from seeping out of storage tanks and flowing to a nearby creek: contaminants were pumped from pits, treated and contained on site. November 28, 1995 AMERICAN CREOSOTE WORKS, INC. (WINNFIELD PLANT) ------- June - September 1988, the Potentially Responsible Party (PRP), under an EPA Administrative Order, fenced the site. Site wastes still seeping subsurface into the bayou and soil surface wastes present a direct contact threat. Health Considerations: Direct contact with site risks and potential for drinking water contamination. Other Environmental Risks: Site wastes leading into adjacent bayou and potentially impacting biota.

Cleanup Measurements This site continues to contaminate Creosote Branch and is unusable as commercial or residential property. The town of Winnfield is economically depressed. It was one of the early Administrative Improvement initiatives (a "Lightening ROD" site) that combines speed with community involvement. Compared to a national average of 8 years, Region 6 required little more than 2 years to progress from proposed addition to the NPL to start of final Remedial Action. In developing the bid specifications, EPA involved local government and Chambers of Commerce. EPA's remedial action will therefore boost local employment during cleanup, return the property to usable conditions and eliminate the sources of contamination.

The site is south of West Hall Avenue in Slidell and north of and adjacent to Bayou Bonfouca. Approximately 26,000 residents live in the surrounding community. Nearest residence potentially impacted by the site is approximately 400 feet from the site, across the bayou to the southwest. Nearest drinking water well is approximately 1/4 mile northeast of the site. The site was used for commercial operations involving the treatment of wood products with creosote. The site encompasses approximately 52 acres. There are eight highly contaminated creosote areas at the site. The northern half of the site is heavily wooded. The site is bordered on the east by a drainage ditch, on the west by a creek, and on the south by Bayou Bonfouca. The contaminants have been found in the bayou. Seven stratigraphic layers were encountered in the first 60 feet during the Remedial Investigation of the site. Three ground water systems were encountered at the site, including a surficial aquifer, a shallow artesian aquifer at 30 feet, and a deep artesian aquifer at 60+ feet. The elevation of the 100-year floodplain is 9 feet (MSL). Most of the site would be inundated by a flood of this elevation. Wastes and Volumes The principle pollutants at the Bayou Bonfouca Superfund site include Polynuclear Aromatic Hydrocarbons (PNAs) - Creosote Compounds.

History: The Bayou d'lnde area is an industrialized area where several petrochemical and agrochemical plants manufacture and process diverse products such as petroleum, sodium hydroxide, chlorine, teflon, butadiene, synthetic rubber, trichloroethylene, and perchloroethylene. A preliminary assessment(PA) report was completed by EPA on September 11,1987. The site inspection (SI) was completed by EPA on January 18, 1988. The expanded site inspection (ESI) report was completed by EPA on September 28, 1993. The results of the ESI sampling documented an observed release of both organic and inorganic" compounds to the surface water. The NPL Hazard Ranking System (HRS) package for the site on February 3,1995. The EPA is awaiting for a letter from the Governor of Louisiana before taking further action to list the site on the NPL. The site is currently being evaluated by a Governor-appointed task force. EPA staff, LDEQ, NOAA, US Army Corps of Engineers, and US Fish and Wildlife Service formed a workgroup and held a meeting on March 23,1995, to discuss the site. It was decided that the dredging should move forward, but that the dredge spoil should be adequately characterized. EPA and the workgroup established data quality objectives for the EPA contractor sampling event and provided comments on the contractor's sampling and analysis plan. One of the larger and more involved PRPs at the site, Pittsburgh Paint & Glass (PPG) has initiated an ecological risk assessment for Bayou d'lnde under the RCRA Corrective Action. The Phase I of ecological risk assessment is scheduled to be completed in 1997 and Phase II is scheduled to be completed in 1999. Health Considerations: Human Ingestion of bioaccumulated contaminants in marine life from fish and shellfish harvesting in the bayou and connected waterways by local and cominercial fishermen. Other Environmental Risks: The Calcasieu River, Lake Charles, and Prien Lake are estuarine in nature and have been designated for the usage of primary and secondary contact recreational use and the propagation of fish and wildlife. There are several delineated wetlands that are considered sensitive environments along Bayou d'lnde, PPG Canal, and the Calcasieu River. Recreational fishing occurs in Bayou d'lnde and the PPG Canal as well as recreational and commercial fishing occurs in the Calcasieu Ship Channel, Calcasieu River, and Prien Lake.

Setting: Nearest residence is approximately 100 feet from the northern property line of the site. Nearest drinking water well is located on the residence about 100 feet away from the site. The surrounding land to the east and south are covered by dense vegetation arid swamp. The areas to the north and west are primarily residential and agricultural. The residential areas are sparsely populated. 25 acre site - an abandoned landfill that accepted both municipal and industrial wastes. One large pond (12 acres) and three small ponds (total approximately one acre) exist on-site. It is estimated that 6,400 drums are buried on-site. Hydrology: The site is underlain by approximately 250 feet of very plastic clays with low permeabilities. Within this clay formation is a clayey/silty sand formation that varies between 3- 10 feet in thickness, and is located 30-50 feet below the ground surface. At 200 feet is another sand formation that is approximately 30 feet thick. This layer is referred to as the Deep Sand Aquifer. The drinking water aquifer is called the Norco aquifer and lies below the Deep Sand. The Norco Aquifer is separated from the Deep Sand by 10 feet of clay. The upper sand zone (30 feet) is contaminated with low-level organics (HCB). There are no known users of this zone. The Norco is not contaminated and the potential for contamination is considered negligible. The Norco is an artesian aquifer that is free-flowing for most of the year. November 29. 1995 ------- Wastes and Volumes Principle pollutants include the following: Hexachlorobenzene (9,500 ppm on-site waste) Hexachlorobutadiene (8,600 ppm on-site waste) Volume: The estimated total volume of material buried on-site is 220,000 cu. yds., including the municipal waste. The ROD calls for excavating approximately 15,000 cu. yds. of drums and bulk sludges as source control. The volume of on-site surface water is estimated to be 22,000,000 gallons, with about 21,500,000 gallons being located in the large pond.

The site was then permitted for the disposal of municipal wastes (Ascension Parish Sanitary Landfill). Environmental Controls Company, with Cleve Reber as president, leased the facility in 1970, and from 1970 to 1974, both municipal and industrial wastes were disposed of at the site. The site was abandoned in 1974. In 1983 the State fenced the site. July 1983, EPA conducted an emergency action removing 1,100 surface drums and waste piles. A thin clay cap was placed over the areas thought to contain buried drums and wastes. In 1984 and 1986, EPA conducted two comprehensive field investigations that indicted all significant contamination was restricted to the site. EPA completed the RI/FS in September, 1986. EPA signed a ROD in March, 1987. EPA completed all design activities in February, 1990. EPA issued UAO and the RA was initiated by the PRPs in April, 1991. Health Considerations: Direct contact with on-site wastes. Potential for drinking contaminated ground water from currently unused water-bearing formation beneath site. Potential for cross-contamination between the shallow sand zone and deep drinking water aquifer of deep wells drilled in the future. Other Environmental Risks: Potential for fugitive volatile emissions during construction (to be evaluated in the design). Record of Decision Signed: March 31,1987 The remedy includes on-site thermal destruction (incineration) of drums and bulk sludges; RCRA cap. Other Remedies Considered 1. No action 2.

Federal contractors performed RD. Currently in RA Phase; excavation and incineration of wastes were completed in October 1995. The remaining activities consisting of capping the site and providing vegetative cover is expected to be complete by August 1996. Cleanup Measurements The EPA has determined that fencing of the site and the removal of contaminated drums and waste piles have significantly reduced the potential of exposure to contaminants at the Cleve Reber facility while final cleanup activities are underway. Implementation of the selected source control remedy will permanently treat site wastes. Because the site will be capped, it will not be available for future residential or industrial/commercial development.

Vermilion Parish The Remediation Process Site History: Inactive facility, which handled wastes primary associated from oil and gas exploration. The company operated from approximately 1969 until 1984 when it filed for bankruptcy. Many types of oilfield wastes were dumped in two main pits on the site which created about 15,000 cubic yards of contaminated sludge. Waste was dumped illegally and indiscriminately at the site and the owner/operator both falsified and destroyed records. Site ownership is in question, however, it is believed that because the site owner is bankrupt and taxes have not been paid on the property, the site is owned by Vermilion Parish. March - May 1990 and February - March 1991, EPA emergency removal funds used: to repair fence, replace warning signs, collect and analyze samples, construct holding levee, pump and treat waste water from pits. April 1992, due to heavy rainfall, waste water from pits was pumped and treated again. A total of 1,250,000 gallons were pumped and treated during emergency removal actions. The interim action, Operable Unit 2, was performed by 15 PRPs under a 12/11/92 unilateral Administrative Order and completed in January 1994. This action consolidated and covered the sludges so that rainwater could not accumulate on them and become contaminated.

The Lake Charles Gas Company operated the plant until 1924. The plant was operated by the Lake Charles Electric Company in 1925, and by the Louisiana Electric Company, Inc. in 1926. GSU operated the plant between 1927 and 1932, when manufactured gas production ceased at the facility, and the property was reportedly sold to United Gas Public Service Company. November 29, 1995 GULF STATES UTILITIES (GSU-North Ryan Street) ------- The annual production of gas during the years of operation at the North Ryan Street Site ranged from approximately 50 to 85 million cubic feet. Manufactured gas was phased out in 1932 when natural gas service became available to the city vof Lake Charles. GSU currently operates and matains the service center at the site. The coal tar by-products generated during gas plant activities were reportedly disposed of into marshlands west of the gas plant. The size of the wetlands area was approximately 6 acres. After the gas plant ceased operation, the wetlands area was used as a landfill for the disposal of electrical equipment and poles, appliances, and other debris. Transformers, capacitors, drums containing used transformer oil were also reported to have been disposed of in this area. By 1980, the area was at its capacity and was filled and covered with shells and soil. This area is now used as an equipment storage area. An area of exposed coal tar, referred to as the tar outcropping (approximately 8 feet by 8 feet), has been identified at the northern portion of this former wetlands area. GSU has placed an aluminum covering over this seep area (observed on site trip 8/17/95). The manufactured gas plant (MGP) structures have been dismantled; however, remnants of the gas plant foundation are still present onsite and the area is currently used for storage. The crude oil storage tanks were reportedly fill in by 1990 and the gas holder foundation is still visible onsite (4-foot high structure). Potential problems were first identified in 1988 during an inspection conducted by the Louisiana Department of Environmental Quality (LDEQ). In September 1988, LDEQ issued a compliance order to GSU to conduct remedial activities at the GSU-North Ryan Street site. GSU conducted phased investigative work required under this order beginning in December 1988 and continuing through October 1990. In response to concerns over the quality of investigative work being conducted, EPA conducted a site inspection (SI) at the site which included sampling activities during the week of October 1,1990, and the completion of an SI report in September 1992. Samples collected during SI field activities from Calcasieu River sediments revealed that contaminants attributable to the GSU-North Ryan Street facility were being released to the Calcasieu River. In 1992, EPA began informal negotiations with GSU on site remedial strategy. However, these negotiations were not concluded due to a lack of resources at EPA and GSU's unwillingness to proceed without deferrment on the NPL ranking process. The Site was proposed to the NPL on February 13,1995. GSU, EPA, and LDEQ have agreed informally upon a site strategy which includes an Engineering Evaluation and Cost Analysis (EE/CA) in support of a non-time-critical removal action and a Remedial Investigation and Feasibility Study for any concerns not addressed as part of the EE/CA (e.g., groundwater connection to river, etc.). Health Considerations: Potential direct contact threat for onsite workers and trespassers with surficial coal tar residue in soils and sediments onsite. Potential migration of contaminants into groundwater and/or surface water increases potential risk of exposure for off-site receptors. The Calcasieu River, a recreational fishery, is within 60 feet directly north of the GSU-North Ryan Street facility. Lake Charles and Prien Lake are within 15 miles of the site in the Calcasieu surface water system and are also recreational fisheries. GULF STATES UTILITIES (GSU-North Ryan Street) November 29, 1995 ------- Otfwr Environmental Risks: The Calcasieu River, Lake Charles, and Prien Lake are estuarine in nature and have been designated for the usage of primary and secondary contact recreational use and the propagation of fish and wildlife. Wetland areas contiguous to surface water downstream of the site are abundant.

The former refinery site consisted of about 215 acres. Bossier City (population 52,721 in 1990) The site is primarily urban. In 1966 and 1967, the site was cleared for development. From 1968 to the present, the site has been fully developed. Private residences, multi-family dwellings, and commercial and light industrial establishments now cover a large portion of the former refinery site. The site is located approximately 1,800 ft. northeast of the Red River. The Red River flows in a south to southeasterly direction across Bossier and Caddo Parishes and eventually empties into the Mississippi River. The uppermost occurrence of ground water is in the Quaternary age alluvial deposits of the Red River. Ground water in the alluvial deposits is generally under artesian pressure. Wastes and Volumes Concentrations of lead up to 11,000 ppm in some surface soils accessible to the public. Floating, free-phase hydrocarbon liquid on shallow groundwater (1,234,000 gallons). Hydrocarbon gases were detected in the soil on over 25% of the former refinery site. Tar-like material containing polynuclear aromatic hydrocarbons oozes to the surface in some residential and commercial areas. More than half a dozen waste deposits are buried under developed properties.

The site included a 120-acre bulk storage area and a 95- acre refinery process area. 1936 to 1948- Arkansas Fuel Oil Company operated the refinery. 1948- refinery operations shut down and process equipment was dismantled leaving tanks, bulk storage and railroad tank car cleaning operations. 1953- the Arkansas Fuel Oil Company merged with Arkansas Natural Gas Corporation to form the Arkansas Fuel Oil Corporation (AFOC). November 29, 1995 HIGHWAY 71/72 (OLD CITQO) REFINERY ------- 1955- tanks and bulk storage were leased to third parties. 1961- AFOC's name was changed to Cities Service Oil Company. 1967- Site was cleared of tanks and refinery equipment for development as a commercial and residential area. 1982- Cities Service Oil Company was acquired by OXY USA, Inc. 1986- the site was evaluated by using the old (no ingestion pathway) HRS model; it scored below 28.5. 1988- EPA referred the site to LDEQ for action under State authority. 1990- 47 families were evacuated from an on-site apartment complex due to high indoor air quality problems related to hydrocarbon gas seepage. (Several units are still unoccupied). Two hotels periodically close several first floor rooms due customer complaints of noxious odors and headaches. 1991 to 1994- Site was investigated by OXY USA, Inc. (OXY) under an administrative agreement with LDEQ. The investigation included soil, surface and ground water samples. 1992- EPA conducted an expanded site inspection to reevaluate the site using the revised HRS model that reflects ingestion pathway. 1994- OXY and LDEQ announce that studies show no emergency health risks on site, potential for long term health risks are recognized. LDEQ asks EPA to complete site evaluation under federal authorities and resources. 1995- The Highway 71/72 (aka "Old Citgo) site was proposed for addition to the e National Priorities List of Superfund sites. Health Considerations: Areas where lead wastes are in surface soils could present health threats to children. Indoor air pollution may render living units unfit for human habitation. Liquid hydrocarbons on surface groundwater may be a source of indoor air pollution. Buried wastes may present a health threat if excavated and improperly disposed of in the future. Other Environmental Risks: Ecological risks are indeterminate at this time due to the urban nature of the site.

OXY submitted over 2,000 pounds of comments in opposition to proposed NPL status. November 29, 1995 HIGHWAY 71/72 (OLD CITGO) REFINERY ------- Special Notice letters were sent to OXY on June 5 requesting a good faith offer to removal lead contaminated soils and complete hydrocarbon contamination sudies. EPA's July, 1995 appropriations legislation chided the agency for adversely affecting the Bossier City economy and for requiring unnecessary additional tests. In a July 21 meeting facilitated by Congressman McCrery's staff, EPA met with OXY, LDEQ, and Bossier City officials to discuss concerns of all parties. As a result of this meeting, EPA proposed an 'Agreement in Principle' among participants. By September 10 all four parties (EPA, LDEQ, OXY, and Bossier City) signed the Agreement in Principle. The Agreement provides for: EPA to precede to remedy selection without additional preliminary testing: OXY to remove surface soils with more than 500 ppm lead under an administrative order on consent. OXY and EPA to agree to a judicial consent decree that provides for pumping and treatment of liquid hydrocarbons on shallow groundwater, corrective action at living units with indoor air pollution caused by the site, and a trust fund to pay for disposal of wastes uncovered in the future. the City and State will establish institutional controls for the site. Cleanup Measurements Innovative partnership with PRP's and the community- The Agreement in Principle unifies government interests at the site and accelerates site actions. Instead of up to 8 years of additional study (the national average for these types of sites), final cleanup of contaminated soils will begin less than a year from the proposed addition of the site to the NPL. The agreement also provides for the community to avoid the 'stigma' of Superfund designation since final placement on the NPL will not be needed while OXY follows thorough on site agreements. HIGHWAY 71/72 (OLD CITGO) REFINERY November 29, 1995 ------- ------- LOUISIANA AR AMMUNITION PLANT LOUISIANA EPA ID# LA0213820533 Site Description Location: EPA REGION 6 GRESSIONAL DISTRICT 05 Webster Parish Population: Setting: Hydrology: 22 miles east of Shreveport on U.S. Highway 80, in Bossier and Webster Parishes. Approximately 10,250 people live in this predominantly agricultural area, within 2 miles of the site. Nearest drinking water well is 1,968 feet. The installation covers 14,974 acres of level to slightly rolling forest land near the towns of Minden and Doyline. The HRS ranking was based on 16 one-acre leaching pits. (Area P.) The Terrace aquifer lies approximately 20 feet below land surface and is reportedly used for drinking water in surrounding areas. Water supplies on the facility are provided by the 300 foot sands (Wilcox aquifer). Analytical tests performed to date show that no contamination of the area drinking water wells has occurred, and that contamination has not migrated from the shallow aquifers to the deeper aquifers. Migration of the waste appears to be retarded in the vertical direction by the Cane River Formation (CRF). The CRF forms a lower hydrogeologic boundary to the Terrace Aquifer and an upper confining unit for the Wilcox Aquifer acrols most of the installation. The updated Remedial Investigation, however, shows that the CRF pinches out west of Area P. This creates a situation where the upper Terrace deposits lay directly on top of the Wilcox formation. Thus, a possible hydrogeologic connection between the contaminated Terrace aquifer and deeper Wilcox aquifer does exist. The Army contends that a Corps of Engineers study shows that no real connection exists because the deeper aquifers of the Wilcox are overlain by substantial clay members of this same formation. Wastes and Volumes The shallow ground water is contaminated by explosive wastes including the explosives, RDX up to 27,000 parts per million (ppm) and TNT up to 25,000 ppm. November 29, 1995 ------- The Army incinerated 105,000 tons of contaminated soils and sludges from Area P.

The current contractor is Thiokol Corporation. The Phase I investigation was completed by the Army in May 1978, and was received by EPA in January 1985. The Phase II, Stage 1 investigation was completed in September 1982. November 29. 1995 LOUISIANA ARMY AMMUNITION PLANT ------- RI for ground water was completed in January 1987. RI/FS for soil contamination in Area P was completed in August 1987. An updated RI for the ground water is ongoing. Sampling began in June 1990, and should be completed in early 1991. , 4 , FS for ground water was completed in 1993. EPA and Army agreed on schedule for completion of the ground water RI/FS in April 1989. An Interim Response Action (IRA) which consisted of incineration of contaminated soils and sludges from Area P was completed in early April 1990. The initial IRA work plan required the Army to excavate the lagoons to a depth of five feet. If soil contamination in the lagoons was greater than 500 ppm of total nitro bodies, the Army would continue to excavate in one foot increments until the soil contamination was 500 ppm or less of total nitro. The excavated soils and sludges were incinerated on-site with the resulting clean ash to be placed back into the lagoons. The original schedule submitted by the Army showed that the IRA would be completed in August of 1990. However, the Army informed the EPA that recent investigations showed that the contamination of Area P is not as extensive as originally stated. The Army formally .requested on October 26, 1989, that the cleanup criteria be revised to reflect a smaller amount of soils and sludges to be excavated and incinerated. The EPA, in conjunction with the Louisiana Department of Environmental Quality, reviewed this request. EPA approved this change to the cleanup criteria on December 21, 1989. The new cleanup criteria required that the lagoon in Area P be excavated to 100 ppm total explosives. This averages a depth of excavation of two to three feet. The excavation and incineration at Area P was completed in April 1990. Capping of the lagoons in Area P was completed in October 1990. Operation and maintenance of the area is ongoing. RI & Risk Assessment approved on March 23,1992, for seven areas. Ground water was put into a separate operable unit to include ground water from all 20 areas under consideration.

November 29, 1995 LOUISIANA ARMY AMMUNITION PLANT ------- LINCOLN CREOSOTE LOUISIANA EPA ID# LAD981060429 REGION 6 CONGRESSIONAL DISTRICT 04 Bossier Parish Bossier City Site Description Location: The site is located in Bossier City, Bossier Parish, in northwestern Louisiana. The site is north of Shed Road, east of Benton Road, south of Montgomery Lane, and west of Airline Drive. Residential neighborhoods border the site to the north, northeast, south and west. Several apartment complexes are located immediately north and south of the site. Portions of the residential neighborhoods to the north and northeast and the apartment complex to the north make up the area of study for the offsite portion of the site. Population: Bossier City (population 52,721 in 1990) Bossier City, Shreveport and Barksdale Air Force Base form a metropolitan area of over 275,000. Setting: The former wood treatment plant encompasses approximately 20 acres. Lincoln Creosote is an abandoned wood treatment facility that was operated from approximately 1935 to 1969 by several different owners and operators. The amount of the surrounding neighborhood to be included as a part of the site is not yet determined. Hydrology: The most shallow ground water at the Lincoln Creosote site occurs within the sand and gravel layers of the Red River Alluvium. The water levels at the Lincoln Creosote site range from about 6.0 to 7.5 feet below ground surface. However, the ground water is reported to be partially confined below a 20-foot thick surficial clay unit and actual depth to water in the alluvial aquifer may be deeper than observed in the onsite monitoring wells. Ground water was shown to flow in an easterly direction in the shallow alluvial water-bearing zone. The Lincoln Creosote site is within the Red River Drainage Basin. The Red River is about 0.4 miles west of the site. The Bossier City Area is drained almost entirely by the Red River and its extensive network of small tributaries. The tributaries eventually flow into the river to the southeast due to the natural and manmade levees along the river. Drainage is poor and slow due to the flat topography. November 29, 1995 ------- Wastes and Volumes Treatment processes for the plant included the use of creosote, pentachlorophenol (PCP), and chromated copper arsenate (CCA). The contaminants of concern are the creosote-related polycyclic aromatic hydrocarbons (PAHs) or semivolatile organic compounds, PCP, chromium, copper, and arsenic.

From 1935 to 1950, the site was operated by the Lincoln Creosote Co., and from 1950 to 1969 by the Joslyn Manufacturing and Supply Co. The Koppers Co. owned and dismantled the site from 1969 to 1971, but never operated the facility. Since that time, the property has been sold a number of times in several parcels to different owners. During site operation, wood products such as railroad ties and utility poles were pressure- treated using creosote, CCA and PCP as preservatives. Upon closure of the facility, most buildings, tanks, impoundments and other structures were removed. Former process areas were covered with fill and revegetated. While much of the former facility has remained vacant and undeveloped, a mini-warehouse facility and a commercial building have been placed on the northwest portion of the site. In 1985, EPA conducted a site investigation and found high concentrations of creosote-related semivolatile compounds in onsite soil samples. A remedial investigation completed by the Joslyn Corp. with oversight of the Louisiana Department of Environmental Quality in 1989, showed significantly elevated concentrations of numerous creosote-related semivolatile compounds, PCP, chromium, and arsenic in onsite soils. Remedial activities at the wood treatment site began in February 1992 under State authority and included excavating and disposing of contaminated soils offsite. During an expanded site investigation conducted by the EPA in March 1992, high concentrations of creosote-related semivolatile organic compounds were detected in the soil samples collected on residential and commercial properties around the site. The site was proposed for the National Priorities List on January 18,1994. In June 1994 EPA began an Expanded Sampling Investigation, Remedial Investigation, and Risk Assessment in the neighborhood surrounding the Lincoln Creosote site. Sampling was completed in late July. A draft report was submitted to EPA in January 1995. An Engineering Evaluation and Cost Analysis (EE/CA) Approval Memorandum was signed for a removal in a portion of the neighborhood surrounding the site on August 23,1994. This will enable EPA and Joslyn Corporation to pursue a possible removal action in one portion of the neighborhood". The EE/CA and EE/CA Fact Sheet was released to the public on March 23, 1995. 30-day public comment period ended on April 21,1995. Health Considerations: Residents in the study area have been contacted regarding recommendations on potential long-term health risks by the Agency for Toxic Substances and Disease Registry (ATSDR). Soil samples from some residential properties in the area show elevated levels of PAHs which are a group of chemicals formed from the incomplete combustion of coal, oil, and other organic substances and are often found in creosote and tar-like substances. Exposure to these chemicals, at the levels found in the area, could cause a slightly increased risk of cancer. LINCOLN CREOSOTE November 29, 1995 ------- Other Environmental Risks: There appears to be no significant environmental or ecological risk from the site as it lies in a highly urbanized area of Bossier City. Record of Decision There is no ROD completed to date. An Action Memorandum was completed for the non-time- critical removal action that addresses soil contamination in off-site areas. Soils in the residential areas above 3 ppm total carcinogenci PAHs will be excavated and disposed of off-site. The residentail areas will be backfilled and restored.

Weston PRP Prime Contractor: ERM - Southwest Cost Recovery: PRPs Identified: 4 Viable PRP: 1 Present Status and Issues During the operation of the now-abandoned facility, waste water from the wood-treating process was discharged from the Lincoln Creosote facility into the natural drainage pathways surrounding the facility. It is suspected that the waste water included wood-treating wastes and other organic and metal contaminants associated with the wood-treating process. Review of historical drainage pathways around the facility during its period of operation indicates that releases of waste water would have flowed to the northeast/east, away from the site into drainage ditches that are now located in a developed residential area. The undeveloped portion of the former facility property is fenced to restrict access. Large residential neighborhoods border the Lincoln Creosote facility to the north, northeast, south and west. A U.S. Department of Housing and Urban Development (HUD) apartment complex is located immediately north of the facility, and another apartment complex is located to the south. Areas of commercial development are present to the east and west. Areas to the south are separated by a railroad line. LINCOLN CREOSOTE November 29, 1995 ------- A removal action for one area of the residential neighborhood will be addressed through an administrative order with the PRPs. PRPs have been sent special notice letters for the performance of the non-time-critical removal action. A good faith offer was received from the PRPs on 11/1/94. An EE/CA Fact Sheet summarizing a proposed non-time-critical removal action was issued 3/23/95. An EPA Action Memo was completed in August 1995. An Administrative Order on Consent was signed by Joslyn Corporation on October 31,1995 for implementation of the non-time critical removal action. Implementation of the soil removal activities in the off-site areas is expected to start in January 1996.

The horizontal ground water gradient is thought to vary during the year, but generally is anticipated to be away from the Mississippi River and to be less than one foot per year. The vertical gradient varies during the year, but is generally downward, away from the River, and is estimated to be fairly steep during average Mississippi River flow conditions.

November 29, 1995 PAB OIL & CHEMICAL SERVICE, INC. ------- PETRO-PROC OF LOUISIAN LOUISIANA EPA ID# LAD057482713 Site Description REGION 6 ONGRESSIONAL DISTRICT 04 East Baton Rouge Parish Location: The Petro Processors Inc. site consists ot two locations near Scotlandville, East Baton Rouge Parish, Louisiana, about ten miles north of the City of Baton Rouge. The Scenic Highway Site is located just west of US Highway 61 and north of the intersection of Scenic Highway 964 and US Highway 61. The Brooklawn Site is located about 2 miles west, southwest of the Scenic Site. Population: The community is predominantly rural with a few houses located about 800 to 1000 feet from the border of Scenic Highway. Setting: Nearest residence is about 3,000 feet from the site. Nearest drinking water well is 3,000 ft. upgradient of the site. The Petro Processors site is comprised of two former petrochemical disposal areas situated about 15 miles apart: the Scenic Highway and Brooklawn areas, totalling 77 ac. Brooklawn is the larger of the two areas, currently estimated at 60 acres. Bayou Baton Rouge meanders around both Scenic and Brooklawn and fingers out into Devil's Swamp. Bayou Baton Rouge historically ran through both Brooklawn and Scenic, but was rerouted during remdial activies at each site. Most of the Brooklawn area was covered by a soil cap, seeded, and contoured to control erosion. In 1994, a full scale treatment facility was constructed to treat contaminated groundwater and non-aqueaous phase liquids (NAPLs) recovered. Approximately 98 sumps have been placed and are in operation at the Brooklawn Site. Recovery wells in operation total about 136, with about 163 wells installed of 214 planned. Brooklawn still has one disposal pond which remains partially open ("Lower Lagoon") where drill cuttings are deposited; all other pits and two former ponds ("Upper Lagoon" and "Cypress Swamp") have been filled and covered. The Scenic Site is now covered by a soil cap, seeded, and contoured to control erosion. Recovery wells have not yet been placed to contain the shallow groundwater, but a system similar to that employed at Brooklawn is being designed. Although phase separation modules would be installed, contaminated water may be pipelined to Brooklawn for treatment and NAPLs shipped over a non-public road connecting Brooklawn and Scenic. Hydrology: Portions of both sites are on the Bayou Baton Rouge flood plain. The bayou flood plain at Brooklawn is also on the Mississippi River flood plain; the Mississippi flood plain immediately south of Brooklawn (Devil's Swamp) is a Wetlands. Pleistocene terrace deposits are predominately clays, while alluvium deposits are interlayered silty clays and sandy silts. The shallow ground water regime is referred to as - 40 MSL zone. The deep groundwater regime of concern is the "400-foot sand". Receptor analysis modeling has been conducted (and is constantly updated with new information obtained from recovery well installation) to protect the "400-foot sand". November 29, 1995 ------- Wastes and Volumes The site's principle pollutants are petrochemical wastes including the following: - Chlorinated Hydrocarbons (Hexachlorobutadiene is predominant contaminant) - Polycyclic Aromatic Hydrocarbons (PAHs) - Heavy Metals - Oils Site Assessment and Ranking NPL LISTING HISTORY Site HRS Score; 41.44 Proposed Date: 9/8/83 FinaJ Date: 9/81/94 :. NPL Update: No. 1 Site Map and Diagram To Mississippi River Area #1 - Scenic Highway Site Area #2. Brooklawn Site November 29. 1995 PETRO-PROCESSORS OF LOUISIANA, INC. ------- The Remediation Process SHe History: The Scenic Highway Site originated as a borrow pit used for petrochemical waste disposal from 1961-1974. Brooklawn was opened in 1969 to accept petrochemical wastes since the Scenic area was filled to capacity. Although filled and closed in 1974, the potential for leachate migration and erosion of the Scenic pit was of concern due to the hazardous constituents contained in the pit. Operations at Brooklawn ceased in 1980, but ponds were left open to the elements. In July 1980, the U.S. Department of Justice, the State of Louisiana, the City of Baton Rouge, and the Parish of East Baton Rouge filed suite against PPI and several generators which had materials transported to PPI. A Consent Decree for site closure was eventually developed with the participation of all parties and court and was entered into the Federal Court's record on February 16, 1984. The Consent Decree required the Defendants to investigate, design and implement a conceptual remedial action specified in the Consent Decree. The conceptual remedy generally called for the excavation and solidification of all visible contamination at the site and subsequent placement into an onsite landfill with an "appropriate" liner and leachate collection system. Additional elements included the solidification, incineration, or off-site disposal of all nonaqueous phase wastes within the lagoons. In addition, recovery wells were to be installed and operated in those areas where free phase organic liquids are present. Shortly after the entering of the Consent Decree, the Industry Defendants (through a company they set up known as NPC Services, Inc.) prepared workplans, conducted investigations, and prepared a Remedial Design and Construction Plan which detailed site remediation activities. Unfortunately, during the early phases of construction (late 1987) NPC's air monitoring program detected the release of volatile hazardous substances from the Brooklawn site. NPC determined that vapor emissions were, or could be, generated from several sources. NPC subsequently reported in a Supplemental Remedial Action Plan ("SRAP") dated December 1988 that "After a thorough study of the causes and effects of these releases it was determined that remediation could not continue under the approved plan without causing further releases". Under the terms of the Consent Decree, NPC was then required to examine alternate methods of remediation. The SRAP presents NPC's evaluation of alternate remediation methods. The various alternatives investigated by NPC included (1) modification of original closure plan by modifying excavation techniques and deploying typical emission source controls such as foams, water sprays, visqueen and soil covers, (2) in-situ volatilization, (3) bioremediation, (4) incineration, (5) solvent extraction, (6) in-situ solidification and capping, (7) vapor containment structures and (8) hydraulic containment and recovery. NPC determined that hydraulic recovery and containment was the only technology that could be safely employed at the present time due primarily to the potential for vapor emissions problems caused by implementation of the other technologies. Upon review, EPA Region 6 rejected the SRAP because it did not contain a sufficiently rigorous evaluation of the alternate technologies. EPA subsequently embarked upon its own review of possible alternative remediation technologies. Upon completion of its eighteen month long study, EPA concluded that two other technologies in addition to hydraulic containment and recovery had merit. These two alternatives included air/steam stripping and in-situ soil flushing. However, EPA recognized that these technologies needed to be bench-scale and pilot tested before EPA could argue their merit to a Federal Judge. PETRO-PROCESSORS OF LOUISIANA, INC. November 29, 1995 ------- The Federal Judge recognized EPA's concern and ordered Louisiana State University (LSU) to conduct research on the applicability of alternate technologies and to act as his expert witness. to resolve technical disputes between the Industry Defendants and EPA. LSU has almost completed their fifth year of research (10/30/95). The end result of all the discussions between EPA, the State of Louisiana and the Federal Court, was an amended Consent Decree in 1989 which specified the implementation of hydraulic containment and recovery. NPC subsequently began additional investigation, design and construction activities necessary to implement the new remedy. Haalth Considerations: Spontaneous ignition of the waste resulted in fires in the upper lagoon on several occasions. In 1969, a spill from the lagoons contaminated portions of a nearby ranch and 30 cattle were killed. Site is located over the "400-foot sands", a major drinking water aquifer. Oth«r Environmental Risks: Lagoons are in the Mississippi River flood plain. Bayou Baton Rouge flows by both sites and fingers into Devil's Swamp, a Wetlands area immediately south of Brooklawn. This area is used recreationally for hunting and fishing. Currently a State health advisory covers a portion of Devil's Swamp. Record of Decision Signed: Consent Decree 1984 Amended: Consent Deere 1989 The existing 1984 Consent Decree and 1989 Amendment may be considered a Source Control and Groundwater Containment Remedial Action for the Petro Processors Site. The SRAP, incorporated by reference into the Consent Decree, calls for a system of about 200 recovery and containment wells at the Brooklawn Site, following capping of the contaminated lagoons. A similar system is being designed for Scenic and will be presented to EPA for review and approval in early 1996.

The federal judge presiding over this case would not allow cost recovery for oversight of the Consent Decree implementation; past costs expended prior to the Consent Decree were allowed (total equal to $600,000 per Section 26 if the Consent Decree). Consent Decree entered into the Record on February 17, 1984. Present Status and Issues The existing 1984 Consent Decree and 1989 Amendment may be considered a Source Control and Groundwater Containment Remedial Action for the Petro Processors Site. Site boundaries are well defined by the Remedial Planning Activities Report, incorporated by reference into the Consent Decree. An air emissions risk assessment was conducted utilizing historical data, data obtained before the caps were in place. Excess risks calculated were within or less than the risk range established in the NCP for remedial actions at Superfund sites. All contaminated source areas at both sites, except the lower lagoon at Brooklawn, are capped. About 98 sumps and 136 wells are currently operational for containment and recovery of NAPLs at Brooklawn (163 wells installed of 214 planned).. A similar recovery well system for , the Scenic Highway Site is currently being developed. PETRO-PROCESSORS OF LOUISIANA, INC. November 29, 1995 ------- A full scale treatment facility has been constructed at the Brooklawn location to manage contaminated groundwater and organics currently being recovered from Brooklawn and that planned to be recovered from Scenic. The treatment scheme includes the following: 1) Phase separate water and organics; 2) air strip contaminated water; 3) incinerate fumes from air strippers and incinerate organic liquids from phase separation unit; 4) polish treated water via carbon adsorption; and 5) discharge the water under an NPDES permit. A trial burn (agency oversight testing of the liquid mode operation of the incinerator) was completed the week of November 7,1994 and the facility became fully operational. Testing data for the incinerator, liquid mode, is being reviewed currently to determine final operating specifications for the incinerator. The incinerator is currently operating under interim specifications determined from preliminary data obtained during the trial burn. Indirect risk assessments have been completed for the incinerator fume mode (utilizing data from the compliance test, fume mode testing), and for the incinerator liquid mode (utilizing data from the trial burn, liquid mode testing) at the Petro Site. These assessments are being reviewed by EPA staff currently and final operational specifications should be approved early in 1996. With operation of the new facility, plans were also approved for closing out the upper and lower lagoons. A specification for closure of the upper lagoon was approved by EPA on October 14,1994 and this lagoon is now closed. The lower lagoon will remain partially open to allow disposal of drill cuttings from recovery well installation. Cleanup Measurements Construction of some phases of the remedy, such as the engineered clay fills covering the Brooklawn and Scenic sites, the installation of a trench drain system in Cypress Swamp and recovery wells at Brooklawn, have been completed. These measures have helped to reduce the migration of contaminants and prevent air emissions from the source areas. With operation of the full scale treatment facility, wells can now be added at Scenic to complete the hydraulic containment / NAPL recovery remedy.

The site is located on 54 acres at 999 Canulette Road, just down stream of the U.S. Highway 433 bridge and adjacent to Bayou Bonfouca, approximately 1.5 miles downstream of the Bayou Bonfouca Superfund site. Approximately 26,000 residents live in the surrounding community. Nearest residence potentially impacted by the site is approximately 400 feet from the site, to the southwest. Nearest drinking water well is approximately 1/4 mile southwest of the site. The southeast portion of the site is heavily wooded. The site is bordered on the north and east by Bayou Bonfouca, on the south by Canulette Road and on the west by Bonfouca Road . The contaminants have been found in the bayou. A uniform clay layer was found to underlie the impoundments and most of the site. A contaminated saturated zone exists above the clay layer and ground water movement is toward the bayou in a northwest direction. Another water bearing unit referred to as the upper confined aquifer, which has not been contaminated by the impoundments, was found below the clay and flows to the south. Wastes and Volumes PITS- 35,000 cubic yards of highly contaminated (PAH's) sludges are in several pits and lagoons comprising about 3 acres. » GRAVING DOCK- Sediment contains tri-butyl-tin (estimated 3,000 cubic yards) from decades of hull repair. November 29, 1995 ------- PROPERTY- The facility comprises 53 acres with a wide variety of hot spots including: explosive/volatile paints, soils contaminated with high levels of metal contaminants such as lead and copper, PCB contaminated soils.

In 1954, Canulette Shipbuilding sold the business to J & S Shipbuilding. Records of the site operations by either of these companies is unavailable. November 29,1995 SOUTHERN SHIPBUILDING ------- In 1957, Southern Shipbuilding Corporation purchased the property from J & S Shipbuilding. Southern Shipbuilding Corporation ran the facility from 1957 until 1993, during which time it performed gas freeing, building, docking and repairing operations. The results of EPA's and LDEQ's investigative efforts in late 1992 and early 1993 provided evidence that the site posed significant human health and environmental threat. During the summers of 1993 and 1994, EPA conducted emergency removal actions to provide additional freeboard within the surface impoundments. The removal actions consisted of pumping contaminated water from the surface impoundments, treating it through sand and activated carbon filtration and discharging the treated water to Bayou Bonfouca. In February 1995, sheet piling was driven along the edge of the waterway to prevent catastrophic failure of the existing levee. In April 1995, a removal action took place which consisted of offsite disposal of numerous containers of paints, solvents and other chemicals from the building referred to as the "paint shed". . The investigations showed four types of contamination concerns remaining at the site: 1) Slightly contaminated surface and subsurface soil in proximity of the impoundments area extending from the surface down to about 10 feet; 2) Highly contaminated sludges and soils of the impoundments and over flow areas, and soils in close proximity to these areas; 3) Sediments within and immediately near the graving dock (dry dock); and 4) Slight contamination in sediments of Bayou Bonfouca. Health Considerations: The pits and hot spots at this site all contain highly toxic materials. The property is not safe for human habitation nor is it usable in current state for commercial enterprise. Human health threats also exist for recreation al users of the Bayou. Flooding has occurred in the area and residents along the Bayou have complained that contaminants from the site have been deposited on their residential properties. Other Environmental Risks: Sediments in and around the graving dock are contaminated with tributyltin (TBT), an anti-fouling paint additive, and an extremely powerful toxin. Catastrophic failure of the levees have occurred releasing pit contaminants into the Bayou SOUTHERN SHIPBUILDING November 29, 1995 ------- Record of Decision Signed: July 20,1995 The Southern Shipbuilding Superfund site remedy includes: Offsite incineration of site pit wastes (at nearby Bayou Bonfouca site) Consolidation/capping of soils onsite not addressed by incineration Consolidation/capping of incinerator ash onsite Removal and incineration of tributyltin-contaminated sediments from the graving dock Community Involvement Community Involvement Plan: Developed 01/95 Open houses and workshops: 08/94,12/94, 02/95, 02/95 Community Meetings: 12/94, 01/95, 02/95, 04/95 Original Proposed Plan Fact Sheet and Public Meeting: 03/95 Original ROD Fact Sheet: 7/31/95 Milestone Fact Sheets: Update 07/94, 09/94 Citizens on site mailing list: 253 Constituency Interest: High interest at site.

By integrating all internal and external aspects of the program, the quality and speed promised in the agency's Administrative Improvements concepts were fully demonstrated. The creative approach utilized at this site serves as an example of the kinds of improvements that can be made in Superfund nationwide. In an 18 month period (January, 1994 to July, 1995) the Southern Shipbuilding Team succeeded in achieved as much progress as is normally accomplished by EPA in 10 years. During this period: A Community Advisory Group was formed: More than a dozen formal and informal meetings with concerned citizens and elected officials were held to shape site studies and remedy selection. In addition to a Technical Assistance Grant group, community associations and a Community Advisory Group were actively involved.
