Asbestos Exposure in Louisiana - Lung Cancer and Mesothelioma

Mechanical Insulation Co. in Baton Rouge, Louisiana operated as a mechanical insulation contractor, providing installation, maintenance, and removal of thermal and acoustic insulation on piping, boilers, vessels, HVAC, and related process equipment for commercial and industrial projects in the region. Work of this type historically involved materials such as pipe covering, block insulation, insulating cements, mastics, and textiles; prior to the widespread phase-out of asbestos in these products in the late 1970s and early 1980s, such materials frequently contained asbestos. As a result, employees and subcontractors at Mechanical Insulation Co. - Baton Rouge, LA, as well as other trades working nearby, could have experienced asbestos exposure during cutting, fitting, mixing, or removal activities that generated dust, and during cleanup or handling of stored materials; over time, industry practices shifted to non-asbestos products with increased regulatory controls and protective measures.

Melamine Chemicals in Donaldsonville, Louisiana was a chemical manufacturing facility producing melamine, a nitrogen-rich compound used in resins, laminates, coatings, molding compounds, and adhesives; operations typically involved converting urea to melamine at elevated temperature and pressure, supported by utilities such as steam and condensate systems, boilers, heat exchangers, pumps, compressors, dryers, and packaging, with logistics via truck, rail, and the nearby Mississippi River industrial corridor. The workforce included process operators, mechanics, pipefitters, electricians, instrument technicians, and outside contractors during maintenance turnarounds and capital projects. Possible asbestos exposure at this location could have resulted from historic use of asbestos-containing insulation on steam and process piping, boilers, and reactors, as well as gaskets and packing in pumps and valves and refractory linings in heaters; activities such as insulation removal, equipment repair, or valve and flange work were most likely to release fibers. Individuals who worked at or serviced Melamine Chemicals in Donaldsonville, LA before non-asbestos substitutes became standard may therefore have experienced potential occupational exposure.

Melrose in New Orleans, LA is referenced as a potential asbestos exposure site. There is no additional information available on this site, but it is on the list of sites where asbestos exposure may have occurred.

The Mengel Box Company - Baton Rouge, LA operated as a wood-products and packaging plant in Baton Rouge, Louisiana connected to the larger Mengel Company's box-making division, with typical operations that included receiving and milling lumber, fabricating components, assembling wooden boxes and crates, and shipping finished containers to regional industrial and agricultural customers by rail and truck. As with many mid-20th-century box plants, the facility's use of steam systems for equipment and drying kilns, along with boilers, piping, and maintenance activities, would have involved materials common to the era such as asbestos-containing insulation, gaskets, cements, and roofing products, creating possible asbestos exposure risks for maintenance workers, boiler and pipe crews, machinists, and production employees working around heated systems and repairs. Specific operating dates and detailed plant records for the Mengel Box Company in Baton Rouge, LA are limited, but its role as a wood box manufacturing site fits the company's broader operations, and any asbestos hazards would align with the widespread industrial use of asbestos prior to the 1980s.

There is no additional information available on this site, but it is on the list of sites where asbestos exposure may have occurred. This notice pertains to the Mengel Company facility in Baton Rouge, Louisiana.

The Mengel Company operated a wood-products and packaging facility in New Orleans, Louisiana, as part of the Louisville-based firm's network of Southern plants, producing wooden boxes and crates and processing lumber into veneer and plywood components to serve Gulf Coast shipping, agricultural, and furniture markets; operations typically included sawing, planing, kiln-drying, gluing, and assembly supported by the city's port infrastructure. Like many industrial sites of the early to mid-20th century, the Mengel Company location in New Orleans, LA may have used asbestos-containing materials in boilers, steam and hot-water lines, drying kilns, presses, pipe and equipment insulation, roofing, and gaskets and packing, creating potential exposure risks for production and maintenance workers and contractors during routine operations and repairs; disturbance of aging building materials could also have posed a hazard. This site has been identified among locations where asbestos exposure may have occurred.

Merchants Ice Co Ltd in New Orleans, Louisiana operated as an industrial ice manufacturing and cold storage facility serving the port city's food distribution, seafood, and hospitality sectors, with activities typical of such companies that included producing block ice, providing refrigerated warehousing, and distributing ice and frozen goods; these operations relied on large ammonia refrigeration systems (compressors, condensers, evaporators, and brine circuits) and, especially in mid-20th-century periods, auxiliary steam boilers, extensive piping, and insulation. As with many ice and cold storage plants built or maintained before the late 1970s, asbestos-containing materials were commonly used for pipe and boiler insulation, equipment gaskets and packing, cements/lagging, and sometimes roofing or fireproofing, creating potential exposure risks during installation, maintenance, repair, and demolition for workers such as pipefitters, insulators, mechanics, electricians, and laborers, as well as bystanders and those with take-home exposures. While detailed site-specific histories for this New Orleans, LA location are limited publicly, its operations and potential asbestos hazards align with conditions documented across similar industrial refrigeration and cold storage facilities of the era.

There is no additional information available on this site, but it is on the list of sites where asbestos exposure may have occurred. This note pertains to the Mercier Hotel in New Orleans, Louisiana.

Mercy Hospital in New Orleans, Louisiana was a mid-20th-century, faith-based acute-care facility originally established by the Sisters of Mercy to serve the Mid-City community, offering general medical, surgical, and emergency services; it was later owned by a private hospital operator and renamed Lindy Boggs Medical Center in the late 1990s, with most acute-care operations ceasing after severe flooding from Hurricane Katrina in 2005 and portions of the campus subsequently used for limited or specialized healthcare services. Because the hospital complex dated to an era when asbestos-containing materials were commonly used, potential asbestos was likely present in pipe and boiler insulation, fireproofing, ceiling and floor tiles, roofing, and HVAC components; maintenance, renovation, storm-related repairs, or demolition activities at Mercy Hospital in New Orleans, LA could have disturbed these materials and created exposure risks for construction and maintenance workers, engineers, and building staff if proper controls and abatement procedures were not in place.

There is no additional information available on this site, but it is on the list of sites where asbestos exposure may have occurred.

Merrimack (USS) refers to a U.S. Navy vessel bearing that name, most notably the World War II-era fleet oiler USS Merrimack (AO-37), which transported and delivered fuel and limited cargo to warships and conducted underway replenishment operations in support of combat and fleet activities; ships of this type periodically berthed, resupplied, or underwent repair and overhaul work at major U.S. ports, and New Orleans, Louisiana was a significant Gulf Coast hub for naval and shipyard services. Navy vessels built and maintained in the mid-20th century commonly incorporated asbestos in pipe and boiler insulation, machinery spaces, gaskets, and valve packing, so sailors serving aboard and shipyard workers performing maintenance or refits - particularly during insulation removal or repair work in confined areas - could have faced asbestos exposure in connection with Merrimack (USS) or similar ships operating through or serviced near New Orleans, LA. Specific dates of the Merrimack's activities in New Orleans are not detailed here, but the nature of its operations and the era of its construction make asbestos exposure a recognized concern for personnel associated with this location.

Metairie Park Country Day School in Metairie, Louisiana is a coeducational, nonsectarian independent day school founded in 1929 that serves students from pre-kindergarten through grade 12, with operations centered on college-preparatory academics, arts, athletics, and community programs supported by classrooms, laboratories, arts spaces, athletic facilities, and common areas on its Metairie campus. As a long-established campus with buildings originating and expanded across multiple decades, including pre-1980 periods when asbestos-containing materials were commonly used in U.S. schools (such as floor tiles and mastic, pipe and boiler insulation, and certain ceiling and wall systems), there is potential for legacy asbestos to be present in older structures; under the federal Asbestos Hazard Emergency Response Act (AHERA), K-12 schools are required to maintain an asbestos management plan and conduct periodic inspections. While no specific public reports of hazardous asbestos releases or exposure incidents at Metairie Park Country Day School have been identified, potential exposure pathways could arise during maintenance or renovation work if asbestos-containing materials are disturbed without proper controls.

There is no additional information available on this site, but it is on the list of sites where asbestos exposure may have occurred. This designation applies to Metairie Ridge Nursery Company in New Orleans, Louisiana.

Metairie Towers in Metairie, Louisiana is a multi-story residential condominium complex whose day-to-day operations typically include on-site property management, custodial and maintenance work, building systems oversight (HVAC, plumbing, electrical, elevators), groundskeeping, and periodic repairs and renovations to units and common areas. As asbestos was widely used in building materials through the late 20th century, possible asbestos exposure at Metairie Towers - Metairie, LA could have occurred during original construction or later renovation and maintenance if asbestos-containing materials such as pipe or boiler insulation, floor tiles and mastic, ceiling or wall finishes, roofing, or HVAC duct insulation were present and disturbed, potentially affecting maintenance personnel, contractors, and nearby residents without proper controls. Any intrusive work should be preceded by a materials survey and managed with appropriate abatement or containment procedures.

The Michoud Assembly Facility in New Orleans, Louisiana is a NASA-owned, Marshall Space Flight Center-managed manufacturing campus established during World War II and transitioned to spaceflight work in the 1960s; spanning more than 800 acres with a single factory building covering over 40 acres under one roof, it has produced the Saturn I/IB and Saturn V first stages, the Space Shuttle External Tank, and today supports fabrication and assembly of the Space Launch System core stage and Orion spacecraft pressure vessels through tenants such as Boeing and Lockheed Martin, while also serving as a multi-tenant industrial hub that continued operations after Hurricane Katrina. Because the site's infrastructure dates to mid-20th-century heavy industry, asbestos-containing materials typical of that era - such as thermal insulation on piping and boilers, fireproofing, gaskets, and flooring - have historically been present and are managed under applicable regulations; potential asbestos exposure could have occurred for workers involved in maintenance, repair, or renovation of older materials, particularly before modern abatement and control programs were in place at the Michoud Assembly Facility in New Orleans, LA.

The Michoud Power Boiler - Michoud, LA refers to boiler operations tied to the former Michoud Generating Station in the Michoud area of eastern New Orleans, Louisiana, a fossil-fueled power facility historically run by the local utility (later Entergy New Orleans) that used large steam boilers fired primarily by natural gas, with fuel oil used at times, to drive turbine-generators. Operations centered on boiler firing, monitoring, and maintenance, along with associated turbine, piping, and pump work, supporting electric generation from the mid-20th century until the older steam units were retired in the mid-2010s and replaced locally by newer generation technology. As with many mid-century power plants, the boilers and related systems likely incorporated asbestos-containing insulation, refractory materials, gaskets, and packing, so workers such as boilermakers, pipefitters, insulators, electricians, and maintenance crews at the Michoud Power Boiler in Michoud, LA may have experienced possible asbestos exposure, particularly during overhauls, repairs, and insulation removal.

Michoud Power Boiler #2, located in Michoud, Louisiana (eastern New Orleans), is referenced as an industrial power boiler installation within the area's heavy industrial corridor. Operations at a power boiler generally center on generating high-pressure steam for power or process use, running feedwater and condensate systems, and performing inspections, maintenance, and periodic overhauls to sustain safe, efficient service. Given common historical practices in the power and industrial sectors, equipment such as boiler shells and drums, pipe and valve insulation, refractory linings, gaskets, and packing around pumps and turbines often contained asbestos, meaning workers at the Michoud, LA facility - including boilermakers, pipefitters, insulators, and maintenance crews - could have encountered asbestos during installation, repair, or removal activities, especially when disturbing aged insulation or refractory materials. Specific unit-level details for Michoud Power Boiler #2 are limited in public records.

Mid Stream Fuel Service in Baton Rouge, LA operated as a marine bunkering provider on the Mississippi River, supplying vessels such as towboats and oceangoing ships with diesel fuel and lubricants via bunker barges and dockside transfers, and handling product storage, barge loading, and hose-and-pump fuel delivery to support river traffic serving the Baton Rouge industrial corridor. The Baton Rouge, Louisiana location's work typically involved coordination with terminals and fleets, barge movements, and maintenance of transfer equipment, pumps, valves, and piping used in fueling operations. As with similar midstream fueling and marine service operations, there was potential for asbestos exposure, particularly in earlier decades, because many ships and some shore-side or barge-based equipment historically used asbestos-containing insulation, gaskets, packing, and heat-resistant materials on engines, boilers, steam lines, pumps, and exhaust systems. Barge crews, mechanics, pipefitters, and visiting vessel personnel could have encountered asbestos fibers during tasks such as repairing or replacing gaskets and valve packing, maintaining transfer pumps and flanges, or working in machinery spaces on older vessels. While specific incidents are not documented here, the nature of marine fueling work around legacy equipment and ships built before modern regulations suggests a plausible pathway for asbestos exposure at or associated with Mid Stream Fuel Service in Baton Rouge, Louisiana.

Middle South Services, Incorporated in New Orleans, Louisiana served as the centralized service and engineering arm for the Middle South Utilities system (later renamed Entergy), coordinating system planning, power generation and transmission operations, engineering and construction management, fuel procurement, and administrative support for operating companies such as Louisiana Power & Light, Arkansas Power & Light, Mississippi Power & Light, and New Orleans Public Service Inc.; from its New Orleans base, personnel supported and dispatched work across regional power plants and substations, and maintained corporate facilities. Because mid-20th-century electric utility infrastructure commonly used asbestos-containing materials in boilers, turbines, piping insulation, gaskets, and fireproofing, employees and contractors affiliated with Middle South Services - especially those involved in plant maintenance, construction, or equipment repair before the 1980s - could have faced potential asbestos exposure, and building maintenance or renovation in older office facilities in New Orleans, LA may also have disturbed asbestos-containing materials.

There is no additional information available on this site, but it is on the list of sites where asbestos exposure may have occurred. The Middle South Utilities - Monroe Generating Plant in Monroe, LA is referenced here solely by name and location.

Mississippi Chemical Corporation, a major U.S. producer and distributor of fertilizer and related chemical products, maintained a facility in Baton Rouge, Louisiana that supported the company's regional fertilizer operations; while publicly available, site-specific details are limited, the Mississippi Chemical Corp. facility in Baton Rouge, LA most likely functioned as a river corridor terminal or plant engaged in storage, blending, and distribution of bulk nitrogen and phosphate fertilizers, with associated maintenance of process and utility systems and coordination of truck, rail, and barge shipments. Possible asbestos exposure at this location could have occurred, particularly prior to the 1980s, due to the industry-wide use of asbestos-containing insulation on steam and process piping, boilers and heaters, as well as asbestos gaskets, packing, and transite building materials; workers at highest risk would have included maintenance personnel, pipefitters, insulators, and contractors involved in repairs, outages, or demolition activities.

The Mississippi River Fuel Corp. - Perryville, LA site was part of an interstate natural gas transmission system that moved Louisiana gas north along the Mississippi River corridor, with the Perryville, Louisiana facility functioning as a key compressor/metering location and interconnection point for regional pipelines. Operations at this location typically included gas compression, pressure regulation, metering, and routine maintenance and overhauls of pipelines, engines or turbines, valves, and related equipment. Built and operated during an era when high-heat industrial services commonly relied on asbestos-containing materials, the facility likely used asbestos for insulation on hot piping and equipment, as well as in gaskets, packing, and cements found in flanges, valves, pumps, and exhaust systems. As a result, workers such as operators, pipefitters, insulators, mechanics, and contractors performing installation, repair, or insulation removal at the Mississippi River Fuel Corp. facility in Perryville, LA could have experienced asbestos exposure, particularly during maintenance that disturbed aging insulation and gasket materials.

Missouri Pacific R.R. - Alexandria, LA refers to a Missouri Pacific Railroad presence in Alexandria, Louisiana, associated with the carrier's broader network that provided freight and passenger service across the Midwest and Southwest and later became part of Union Pacific in the 1980s; work at Missouri Pacific locations commonly included local switching, freight handling, track and equipment servicing, and other terminal functions. As with many railroad facilities during much of the 20th century, potential asbestos exposure could have occurred through insulation on steam- and diesel-related components, brake linings, gaskets and packing, pipe and equipment lagging, and asbestos-containing cements and tapes used in shops and on rolling stock, which posed risks to shop crafts (such as machinists, pipefitters, boilermakers, carmen, and electricians) as well as operating crews and laborers handling dusty materials at sites like those in Alexandria, Louisiana.

The Mobil / Magnolia site in Johnson Bayou, Louisiana is associated with long-standing Gulf Coast oil and gas operations historically linked to Magnolia Petroleum (a Mobil predecessor), supporting production from nearby fields and handling activities typical of the region such as well production, separation and treatment, gas compression and dehydration, condensate handling, and pipeline transport. Located in Cameron Parish near key coastal energy corridors, the facility's workforce likely included operators, mechanics, pipefitters, welders, insulators, and outside contractors engaged in routine operations, maintenance, and turnarounds. As with many mid-20th-century petroleum and gas facilities, possible asbestos exposure at this Johnson Bayou, LA location could have arisen from the historical use of asbestos-containing insulation, gaskets, packing, fireproofing, and refractory materials on piping, boilers/heaters, heat exchangers, turbines, compressors, and pumps, with elevated risk during repair, removal, or replacement of these materials.

The Mobil / Tenneco, Bay Refinery in Chalmette, Louisiana was a Gulf Coast petroleum refining complex along the Mississippi River in St. Bernard Parish, historically associated with Tenneco Oil and later Mobil and their successors, that processed crude oil into transportation fuels and other refined products. Typical operations at the Chalmette, LA facility included crude and vacuum distillation, catalytic cracking and reforming, hydrotreating, alkylation, coking, sulfur recovery, and extensive utilities and maintenance support, producing gasoline, diesel, jet fuel, LPG, petroleum coke, and sulfur for regional markets. Like many refineries built or expanded during the mid - 20th century, the site employed asbestos - containing materials in thermal insulation, refractory linings, pipe covering, gaskets, packing, cements, and some protective equipment before safer substitutes became standard, which created potential asbestos exposure risks - especially during maintenance, turnarounds, and demolition - for refinery workers and contractors such as insulators, pipefitters, boilermakers, mechanics, electricians, and turbine operators working at this location.

There is no additional information available on this site, but it is on the list of sites where asbestos exposure may have occurred.

Mobil Oil Company's Johnson Bayou Plant in Cameron, Louisiana was a Gulf Coast natural gas processing site that handled production from nearby offshore and coastal fields, providing gas treating and dehydration, compression, and cryogenic recovery of natural gas liquids with downstream shipment via regional pipelines; after Mobil's merger with Exxon in 1999, the facility's operations became associated with ExxonMobil's broader midstream network. Built and operated during decades when asbestos-containing materials were widely used in oil and gas facilities, potential asbestos exposure at the Mobil Oil Co.- Johnson Bayou Plant - Cameron, LA could have arisen from insulation on high - temperature piping, boilers, turbines, heaters, and heat exchangers, as well as from gaskets, valve and pump packing, fireproofing, and refractory components; the highest risks would have been for insulators, pipefitters, maintenance personnel, welders, and contractors during repairs, turnarounds, and post-storm cleanup common in Cameron Parish. While specific incident records are not presented here, the combination of legacy materials and frequent maintenance typical of gas plants in this region indicates workers and trades at the Johnson Bayou facility may have encountered asbestos, particularly before the 1980s when such materials were still in regular use.

For Mobil Oil Corp. - Johnson Bayou, LA in Johnson Bayou, Louisiana, there is no additional information available on this site, but it is on the list of sites where asbestos exposure may have occurred.

The Chalmette Refinery in Chalmette, Louisiana is a long-standing Mississippi River-adjacent petroleum refinery that has produced transportation fuels and other refined products for decades; historically operated by Mobil Oil Corporation and later by ExxonMobil through the Chalmette Refining, LLC joint venture, it was sold in 2015 and continues to operate today under PBF Energy. With an approximate processing capacity in the range of 180,000-190,000 barrels per day, typical units at the site include crude and vacuum distillation, fluid catalytic cracking, hydrotreating, reforming, alkylation, a coking unit, and sulfur recovery, supplying gasoline, diesel, jet fuel, LPG, and petroleum coke to Gulf Coast and regional markets. Like many U.S. refineries constructed and expanded before the 1980s, the facility historically used asbestos-containing materials for high-temperature insulation on piping, boilers, heaters, turbines, and in gaskets, packing, and refractory linings, creating potential exposure risks for pipefitters, insulators, maintenance crews, and other trades during routine work, turnarounds, and equipment overhauls. Over time, improved industrial hygiene practices, abatement programs, and protective equipment reduced these risks, but legacy asbestos may still be encountered during maintenance on older systems. The refinery's location in Chalmette, LA and its long operational history make it a notable industrial employer in St. Bernard Parish, with ongoing modernization and environmental controls consistent with contemporary refining operations.

For the Mobil Oil Refinery in Thibodeaux, LA, there is no additional information available on this site, but it is on the list of sites where asbestos exposure may have occurred.

The site listed as Moinester (Uss) in New Orleans, Louisiana refers to the U.S. Navy frigate USS Moinester (FF-1097), a Knox-class vessel active during the Cold War that carried out anti-submarine warfare, escort, patrol, and training missions typical for its class; its connection to New Orleans, LA reflects port calls, logistics support, or shipyard services conducted in the area as part of routine Navy activity along the Gulf Coast. As with many Navy ships built and maintained before modern asbestos controls, Moinester incorporated asbestos-containing insulation, gaskets, packing, and other heat-resistant materials in machinery spaces and piping systems, creating potential asbestos exposure for sailors and civilian shipyard workers, particularly during maintenance, overhaul, and repair work performed aboard or alongside the vessel.

Monongahela (Uss) refers to USS Monongahela (AO-178), a U.S. Navy fleet oiler associated with New Orleans, LA through its construction and service work at area shipyards, and it operated as a logistics vessel conducting underway replenishment of fuel, stores, and ordnance for carrier and amphibious groups from the late Cold War into the 1990s, including Atlantic and Middle East deployments. As a large auxiliary with extensive engine and pump spaces, it relied on high - heat and high - pressure systems typical of oilers of its era, and New Orleans, Louisiana facilities supported periodic maintenance and overhauls. Because asbestos-containing insulation, gaskets, packing, deck materials, and fireproofing were widely used on U.S. Navy ships built and serviced in this timeframe, there was potential asbestos exposure for shipyard workers (such as insulators, pipefitters, boilermakers, and machinists) during construction and repair, as well as for sailors and maintenance crews working in machinery spaces, pump rooms, and other confined areas aboard USS Monongahela.

The Monroe Municipal Power Plant, Generating Station in Monroe, Louisiana is referenced as a municipal electric generating facility serving the City of Monroe, with operations typical of such plants that generally rely on boilers and steam turbines with high-pressure piping, pumps, condensers, and electrical switchgear to deliver power to the local distribution system. Throughout much of the 20th century, asbestos-containing insulation, refractory materials, and gasket/packing products were widely used in power plants, so maintenance, repairs, insulation work, and equipment overhauls at the Monroe, LA generating station may have created exposure risks for operators, pipefitters, electricians, mechanics, and contractors. Detailed public information specific to this plant's fuel type, operating years, and present status is limited, but the site appears on lists of locations where asbestos exposure may have occurred.

Monroe Power House in Monroe, LA: There is no additional information available on this site, but it is on the list of sites where asbestos exposure may have occurred.

Monsanto's St. Charles Operations in Luling, Louisiana is a long-standing chemical manufacturing complex on the Mississippi River that has primarily produced agricultural chemicals - most notably glyphosate herbicide and related intermediates - and underwent a major expansion in the mid-2010s to add dicamba capacity; the site, historically known as Monsanto - Luling, LA and now part of Bayer Crop Science following Monsanto's acquisition, supports hundreds of jobs and uses river, rail, and pipeline logistics typical of the Gulf Coast industrial corridor. Built and expanded during the mid-20th century, the facility operated extensive steam systems, boilers, reactors, and piping, and - like many plants of that era - likely incorporated asbestos-containing insulation, gaskets, packing, and fireproofing before tighter regulations took hold in the late 1970s and 1980s; accordingly, potential asbestos exposure would have been most plausible for pipefitters, insulators, boilermakers, maintenance mechanics, and contractors performing repairs or turnarounds at the Luling, LA site, especially during removal or disturbance of older materials, while modern operations follow current abatement and control practices.

Monsanto - New Orleans, LA is on the list of sites where asbestos exposure may have occurred. There is no additional information available on this site, but it is on the list of sites where asbestos exposure may have occurred.

The Monsanto Chemical Co facility in Luling, LA, located along the Mississippi River in St. Charles Parish, has operated for decades as a large-scale chemical manufacturing site, best known for producing agricultural chemicals - particularly herbicide active ingredients and intermediates such as dicamba and glyphosate - and supporting operations like formulation, storage, and distribution by rail and barge; after Monsanto's acquisition by Bayer in 2018, the site continued operating under Bayer Crop Science with significant investment and capacity expansions. As with many mid-20th-century chemical plants, potential asbestos exposure at the Luling, Louisiana site could have arisen historically from thermal insulation on boilers, steam lines, heat exchangers, pumps, valves, and from asbestos-containing gaskets and packing; maintenance, turnaround, and insulation work performed by employees and contractors before modern controls were widely implemented posed the greatest risk, while later abatement efforts and OSHA/EPA regulations substantially reduced routine exposure potential.

Monsanto Chemical Co.'s facility in Luling, Louisiana is a long-standing chemical manufacturing complex along the Mississippi River in St. Charles Parish that has produced agricultural chemicals and intermediates, notably the herbicide active ingredient glyphosate; it remains in operation today under Bayer following the acquisition of Monsanto. Operations at the Luling, LA site have included large-scale synthesis and reaction processes, distillation, bulk storage and loading, and extensive utilities and maintenance/turnaround work to support continuous production. As with many mid-20th-century chemical plants, potential asbestos exposure at this location may have occurred historically due to asbestos-containing thermal insulation on steam lines and process equipment, as well as gaskets, valve and pump packing, and refractory materials that could be disturbed during installation, repair, or demolition activities, with trades such as pipefitters, insulators, millwrights, and contractors at comparatively higher risk prior to modern abatement and control programs.

Monsanto Chemical Company's facility in Luling, Louisiana is a long-operated chemical manufacturing complex along the Mississippi River industrial corridor that has produced agricultural chemicals and intermediates, including components for glyphosate- and dicamba-based herbicides, and it has undergone multiple expansions with continued operation following Monsanto's acquisition by Bayer in 2018; the site includes large-scale reaction, distillation, and formulation units, along with utilities, maintenance, and rail/barge logistics typical of Gulf Coast plants. Given its multi-decade operating history, Monsanto Chemical Company - Luling, LA may have used asbestos-containing materials historically in pipe and equipment insulation, gaskets, packing, refractory linings, and heat-protection products on steam systems, boilers, heat exchangers, and reactors, creating potential airborne exposure risks before modern controls and abatement - particularly for insulators, pipefitters, maintenance and turnaround crews, contractors, and nearby operators when insulation was installed, removed, or disturbed.

Montell USA, Incorporated was the U.S. polyolefins arm of Montell, a major producer of polypropylene and polyethylene resins, and its Lake Charles, Louisiana location operated within the Gulf Coast petrochemical corridor to manufacture or compound plastic resins and support related processing of propylene and ethylene with extensive utilities, piping, reactors, and heat-exchange systems. Typical operations at the Lake Charles, LA site would have included continuous chemical processing, resin finishing and pelletizing, maintenance turnarounds, and on-site utility generation (such as steam and compressed air), staffed by operators, mechanics, pipefitters, electricians, and contractors. As with many petrochemical and plastics facilities built or expanded during the mid-20th century, potential asbestos exposure at this location could have arisen from historical use of asbestos-containing insulation on steam lines and process piping, boiler and furnace refractory, gaskets and packing in pumps and valves, heat exchanger components, and transite panels; the greatest risks would have been during maintenance, repairs, insulation removal or disturbance, and outage work prior to the widespread phase-out of asbestos materials in the 1980s. Ownership and corporate transitions in the industry subsequently folded Montell's U.S. assets into Basell and later LyondellBasell, but the industrial profile of the Lake Charles, Louisiana operations - and the associated historical asbestos hazards common to similar facilities - remains relevant for exposure evaluation.

Moose - New Orleans, LA refers to a local Moose Lodge in New Orleans, Louisiana, part of the Loyal Order of Moose, a fraternal service organization that operates a member social hall and hosts community service, fundraising, and fellowship activities; the facility typically includes meeting rooms, a bar or dining area, and event space staffed and maintained by members and local contractors. Depending on the age and construction of the lodge building, possible asbestos exposure could have occurred in New Orleans, LA during past maintenance, repair, or renovation work if legacy materials common in older structures - such as pipe and boiler insulation, sprayed-on fireproofing, ceiling or floor tiles, joint compound, roofing felts, or HVAC duct insulation - were present and disturbed; those at greatest risk would have been custodial staff, tradespeople, and others in close proximity to such work. Specific building details for this Moose location are not publicly documented here, so asbestos risks should be evaluated based on the building's construction era and any historical renovation records.

The location known as Mopsi Michoud Power Station - Southern Railway, Mill A Switch - Door 4 in New Orleans, Louisiana refers to the Michoud power-generating complex in the Michoud area of New Orleans, LA, historically operated as the NOPSI (New Orleans Public Service Inc.) Michoud Power Station and later by Entergy New Orleans; it was a fossil-fueled facility (primarily natural gas and, at times, fuel oil) that produced electricity for the city using steam boilers, turbines, condensers, and extensive auxiliary systems, with fuel delivered chiefly by pipeline and heavy equipment and materials handled through designated plant entrances and rail-served switches - "Southern Railway, Mill A Switch - Door 4" denotes a specific internal delivery/switch point used for logistics at the site. As with many mid-20th-century power stations, equipment and systems commonly incorporated asbestos-containing insulation, refractory materials, gaskets, packing, and electrical components, creating potential asbestos exposure for workers and contractors - especially insulators, pipefitters, boilermakers, electricians, and maintenance crews - during installation, repair, outages, and later decommissioning or abatement activities; actual exposure would have depended on job duties and time period of work at the Michoud facility in New Orleans, Louisiana.

Morgan City Municipal in Morgan City, LA refers to the city-operated municipal complex and services that support this St. Mary Parish community, including utility functions (electric, water, and sewer distribution), public works, and civic facilities such as administrative offices and the municipal auditorium; day-to-day operations generally include infrastructure maintenance, facility upkeep, and community services for residents and businesses along the Atchafalaya River. Municipal buildings and utility systems constructed or renovated prior to the 1980s commonly used asbestos-containing materials - such as pipe and boiler insulation, gaskets and packing, roofing, floor tiles, joint compounds, and HVAC duct insulation - so past repair, renovation, or demolition work at Morgan City Municipal (e.g., on steam lines, pump stations, mechanical rooms, or building interiors) could have posed asbestos exposure risks to maintenance workers, utility crews, contractors, and tradespeople, while routine occupancy presented minimal risk unless materials were disturbed. Specific, detailed site records are limited, but Morgan City Municipal - Morgan City, LA is among locations where asbestos exposure may have occurred.

There is no additional information available on this site, but it is on the list of sites where asbestos exposure may have occurred.

The Motiva Oil Refinery in Convent, Louisiana was a large Mississippi River-side facility in St. James Parish that processed roughly 200,000-211,000 barrels of crude oil per day into gasoline, diesel, jet fuel, LPG, and petrochemical feedstocks, with major units including crude and vacuum distillation, catalytic reforming, hydrotreating and hydrocracking, an FCC complex, and sulfur recovery; it was integrated by pipeline with the Norco refinery as part of a Louisiana refining system to optimize intermediates and logistics by barge, pipeline, rail, and truck. Built in the 1960s and long operated by Texaco and later through the Shell-Saudi Aramco joint venture (Motiva Enterprises), the site ultimately came under Shell's sole ownership and was idled and permanently shut in 2020 after an unsuccessful sale effort, though it is still commonly referenced as the Motiva Oil Refinery in Convent, LA. As with many refineries constructed and expanded during the mid - 20th century, equipment at this location historically utilized asbestos - containing insulation, gaskets, packing, and refractory materials on pipes, boilers, turbines, heaters, and FCC components, creating potential asbestos exposure risks for insulators, pipefitters, maintenance and turnaround crews, and contractors - particularly before tighter controls and abatement practices became standard in the 1980s and later.

Mount Houmas Plantation in Ascension Parish, LA historically operated as a large sugarcane estate along the Mississippi River, with 19th- and early 20th-century activities that typically included cultivating cane, operating on-site sugar houses with boilers, steam-driven mills, and centrifuges, and maintaining extensive plantation buildings and support infrastructure; in later years, the site in Darrow, Louisiana has been preserved and used for historic interpretation, tourism, hospitality, and ongoing restoration work. During the decades when steam plants, piping, and heavy equipment were standard in sugar production, facilities of this type often used asbestos-containing insulation, pipe lagging, gaskets, packing, cements, roofing, and floor materials, so potential asbestos exposure could have occurred for sugar mill workers, maintenance crews, pipefitters, boiler operators, electricians, carpenters, and renovation contractors, particularly during equipment repairs or building restoration that disturbed aging materials; visitors are unlikely to have been at risk under normal conditions, but anyone who performed abatement or intrusive work would have required appropriate protective measures and compliance with safety regulations.

The Municipal Light And Power Plant - Monroe, LA was a municipally operated electric utility facility that generated and distributed power for the City of Monroe, Louisiana. Operations at facilities of this type typically included running steam-cycle equipment such as boilers, turbines, condensers, pumps, and extensive piping systems, along with fuel handling, water treatment, electrical switchgear, and substations, supported by on-site maintenance. As with many mid-20th-century power plants, asbestos-containing insulation, gaskets, packing, cement, and electrical components were commonly used on high-temperature and high-pressure systems, meaning workers and contractors at the Municipal Light And Power Plant in Monroe, Louisiana may have faced possible asbestos exposure during installation, repair, or removal activities, particularly around boilers, turbines, and steam lines.

For Municipal Power Plant - Monroe, LA, there is no additional information available on this site, but it is on the list of sites where asbestos exposure may have occurred.

The Municipal Power Plant - City of Monroe in Monroe, Louisiana was a city-owned electric generating facility that supported the local power needs of the City of Monroe, with typical operations centered on boilers, steam systems, turbines, fuel handling, and ongoing equipment maintenance and repairs; as with many municipal power plants operating through the mid-20th century, asbestos-containing insulation, gaskets, packing, refractory materials, and certain electrical components were commonly used for heat resistance and fireproofing, creating potential asbestos exposure risks for employees and contractors - particularly those working in boiler rooms, on turbine decks, or in pipefitting, insulation, electrical, and maintenance roles during installation, routine servicing, overhauls, or later renovation and demolition activities.

The site known as Murphy / Ingram Oil - Chalmette, LA refers to petroleum refining, storage, and distribution operations in the Chalmette-Meraux industrial corridor of St. Bernard Parish, historically associated first with Ingram Oil & Refining Company and later with Murphy Oil Corporation; facilities in or near Chalmette, Louisiana processed crude oil into transportation fuels and related products and were supported by tank farms, pipelines, maintenance shops, and river docks serving the Mississippi River. Like many mid-20th-century oil facilities, equipment and materials commonly used at these operations - including pipe and vessel insulation, boilers, turbines, pumps, valves, gaskets and packing, refractory linings, and fireproofing - often contained asbestos, creating potential exposure risks for operators, pipefitters, insulators, boilermakers, electricians, and contractors, particularly during maintenance and turnaround activities before modern controls were adopted.

The site commonly referred to as Murphy Oil - Meraux, LA is a long-standing petroleum refining complex in Meraux, Louisiana (St. Bernard Parish) that processed crude oil into gasoline, diesel, jet fuel, and other products for Gulf Coast and regional markets; it was owned and operated by Murphy Oil USA for decades before being sold in 2011 to Valero Energy, which continues operations as the Valero Meraux Refinery. Located near residential areas east of New Orleans, the facility is notable for the 2005 Hurricane Katrina incident in which a storage tank failed and released roughly 25,000 barrels of crude oil into surrounding neighborhoods, prompting a large cleanup and subsequent litigation. As with many older refineries, the plant's extensive piping, boilers, heaters, and process units historically may have incorporated asbestos-containing insulation, gaskets, and refractory materials, so employees and contractors - particularly insulators, pipefitters, boilermakers, and maintenance crews working before widespread phase-outs in the 1980s or during post-storm repairs - could have faced potential asbestos exposure if proper controls were not in place.

The Murphy Oil Corp. - Mareaux, LA site refers to Murphy Oil's refinery and terminal complex in Meraux, Louisiana (St. Bernard Parish) along the Mississippi River, a facility developed in the mid-20th century to process crude oil into transportation fuels and other petroleum products, with associated storage tanks, pipelines, and marine/rail connections; it operated under Murphy Oil until its divestment to another major refiner in the early 2010s and is also known for damage and a significant neighborhood spill during Hurricane Katrina in 2005. Typical operations at the Meraux refinery included crude distillation, product hydrotreating/reforming, and extensive maintenance and turnaround work involving on-site and contractor labor. As with many U.S. refineries built or expanded before the 1980s, there was potential for asbestos exposure from historical use of asbestos-containing insulation on pipes and equipment, refractory materials in heaters, and gaskets and packing in pumps and valves; potential exposure would have been most likely for insulators, pipefitters, boilermakers, maintenance workers, and contractors during repairs, removals, and cleanup, although controls increased over time and many asbestos applications were phased out or abated.

There is no additional information available on this site, but it is on the list of sites where asbestos exposure may have occurred.

Myrtle Grove Sugar in Plaquemine, Louisiana was a sugarcane processing facility that handled seasonal cane grinding for area growers, converting harvested cane into raw sugar and molasses through crushing, clarification, evaporation, crystallization, and centrifugation, with bagasse commonly burned to generate steam and power for boilers and process equipment. The site's operations would have required extensive steam piping, high-temperature vessels, turbines, pumps, and dryers typical of sugar mills, and, like many industrial plants of the era, asbestos-containing insulation, gaskets, and packing may have been used in boiler rooms, on pipes, and around heat-exposed equipment; maintenance workers, pipefitters, boiler operators, and contractors performing repairs or insulation work would have faced the greatest potential for asbestos exposure, especially during outages or equipment overhauls when lagging was disturbed. Publicly available details specific to ownership and operating dates for Myrtle Grove Sugar in Plaquemine are limited, but its function as a sugar mill places it among industrial settings where historical asbestos use was common.

N. O. Cold Storage Company in New Orleans, Louisiana is a long-established refrigerated warehousing and logistics operator serving the Port of New Orleans, handling temperature-controlled storage, blast freezing, and import/export of products such as poultry, beef, and seafood, along with related inspection, cross-dock, and distribution services. The company's New Orleans, LA facilities have historically been located on or near port terminals to support maritime and intermodal supply chains, coordinating closely with ocean carriers, trucking, and rail. As with many cold storage and industrial facilities built or expanded during the mid-20th century, potential asbestos-containing materials could have been present in mechanical and building systems, including pipe and boiler insulation, valve packing, gaskets in refrigeration equipment, and fireproofing or roofing materials. Possible asbestos exposure pathways would have been most relevant to maintenance and repair personnel, insulation workers, pipefitters, and refrigeration mechanics during installation, servicing, or renovation work, especially where aging materials were disturbed. There is no specific public record cited here of an asbestos incident at this site, but the type and era of operations indicate the potential for occupational exposure in older facility areas.

For Nadler Inc. in Plaquemine, Louisiana: There is no additional information available on this site, but it is on the list of sites where asbestos exposure may have occurred.

Nalco Chemical in Baton Rouge, Louisiana operated as part of the company's regional network supporting the Gulf Coast refining and petrochemical corridor, handling, blending, and distributing water-treatment and process chemicals (including corrosion inhibitors, scale-control agents, and biocides), maintaining bulk storage, packaging/drum-filling operations, and providing on-site or laboratory technical services to nearby industrial clients. As with many chemical and industrial facilities of its era, the Nalco Chemical - Baton Rouge, LA site would have relied on steam and process systems with equipment such as boilers, heat exchangers, pumps, valves, and extensive piping, where asbestos-containing insulation, gaskets, and packing were historically common; this created potential asbestos exposure risks for maintenance workers, pipefitters, insulators, and other trades during installation, repair, or removal activities, as well as during disturbance of aged building materials. Publicly available details specific to this location are limited, but the site's industrial operations and context indicate that asbestos exposure could have occurred through work on insulated piping and equipment, gasket and packing replacement, and related maintenance tasks.

Nalco Chemical's Garyville, Louisiana facility is a specialty chemical plant that supports the region's refinery and petrochemical corridor by manufacturing and blending water and process treatment chemicals - such as corrosion inhibitors, scale-control agents, and biocides - along with associated packaging, bulk storage, and truck/rail distribution operations; the site operates under Nalco Company (now part of Ecolab) and serves nearby industrial clients in and around Garyville, LA. As with many Gulf Coast chemical plants that originated or expanded before the 1980s, legacy equipment and building materials at such facilities often incorporated asbestos-containing insulation, gaskets, and packing on boilers, steam lines, pumps, and valves, creating potential exposure risks for maintenance workers, insulators, pipefitters, and others during repairs or turnarounds before modern controls were in place. While no specific asbestos incidents are documented here, potential exposure at the Nalco Chemical - Garyville, LA site would most plausibly have occurred during disturbance of older thermal insulation or gasket materials in legacy systems.

Nasa Michoud Operations in New Orleans, Louisiana, commonly known as the NASA Michoud Assembly Facility, is a government-owned, contractor-operated manufacturing complex established during World War II for industrial production and transferred to NASA in the early 1960s; it has since supported major programs by producing large rocket stages for the Apollo-era Saturn vehicles, fabricating the Space Shuttle External Tank for decades, and currently building the Space Launch System core stage and Orion spacecraft structures using advanced metal-forming, machining, and friction-stir welding capabilities within one of the nation's largest assembly buildings. Given its mid-20th-century construction and long history of heavy industrial and high-temperature work, the site historically used asbestos-containing materials common to such facilities - such as insulation on pipes and boilers, fireproofing, gaskets, cements, and certain flooring and roofing products - creating potential asbestos exposure risks for trades like pipefitters, insulators, welders, maintenance personnel, and contractors, particularly in earlier decades or during renovations; modern asbestos management and abatement programs have been implemented to address and control remaining hazards at Nasa Michoud Operations in New Orleans, LA.

The Nasa Plant - New Orleans, LA refers to NASA's Michoud Assembly Facility in New Orleans, Louisiana, a government-built manufacturing complex dating to the early 1940s that NASA adopted in 1961 to produce major spaceflight hardware, including Saturn I and Saturn V first stages for Apollo, the Space Shuttle External Tank, and today the Space Launch System core stage and Orion spacecraft structures through contractors such as Boeing, Lockheed Martin, and formerly Martin Marietta. Managed by NASA's Marshall Space Flight Center, the site features one of the largest contiguous manufacturing buildings in the country and extensive utilities typical of heavy industrial operations. Because the facility's infrastructure and many of its systems were installed or operated during periods when asbestos was commonly used, potential asbestos exposure could have occurred, particularly before the late 1970s, from materials such as pipe and boiler insulation, gaskets and packing, spray-applied fireproofing, roofing and floor tiles, cement products, and heat-resistant textiles. The highest risks would have been to maintenance, insulation, plumbing, HVAC, and renovation crews who disturbed legacy materials during routine work or major upgrades, including storm-related repairs in New Orleans, LA. Subsequent regulations and abatement programs significantly reduced these hazards, but historical exposure remains a consideration for past workers and contractors at this location.

Natalbany Lumber Co. in St. Francisville, Louisiana is referenced as a lumber milling and wood-products operation serving the regional timber industry, with typical activities that would have included log intake, sawing, planing, kiln drying, equipment maintenance, and shipment of finished lumber. At lumber mills of this era, steam systems, boilers, drying kilns, and associated piping often used asbestos-containing insulation, gaskets, packing, and cement, creating potential exposure for production workers, millwrights, pipefitters, maintenance crews, and contractors, particularly before tighter regulations took hold in the late 1970s. The St. Francisville, LA facility appears on lists of Louisiana worksites where asbestos exposure may have occurred, though publicly available details on the site's specific operating dates and ownership history are limited.

There is no additional information available on this site, but it is on the list of sites where asbestos exposure may have occurred.

National Bagasse Products in Vacherie, Louisiana was an industrial facility associated with converting sugarcane bagasse - the fibrous residue from cane processing - into commercial materials such as fiberboard or related products; operations typically included receiving and storing wet bagasse from nearby mills, mechanical preparation and refining, drying in steam-heated equipment, forming and pressing boards, and finishing and packaging for shipment, supported by boilers, steam and condensate systems, and maintenance shops. Located in St. James Parish, the Vacherie, LA site would have relied heavily on thermal systems, and potential asbestos exposure may have arisen historically from insulation on boilers, dryers, piping, and valves, as well as from asbestos-containing gaskets, packing, cement, and building materials used prior to the 1980s; bagasse-based products themselves were not inherently asbestos-containing, so any exposure risk would have been primarily occupational for production and maintenance workers and contractors working on hot equipment or during repairs. Publicly available details on specific ownership periods, production volumes, and exact operating dates are limited, but the location has been identified on lists of workplaces where asbestos exposure may have occurred.

This summary concerns the National Bagasse Products Company in Vacherie, Louisiana. There is no additional information available on this site, but it is on the list of sites where asbestos exposure may have occurred.

At the National Brewing Company - New Orleans, LA, there is no additional information available on this site, but it is on the list of sites where asbestos exposure may have occurred.

The National Gypsum facility in New Orleans, Louisiana, was part of the company's network supplying gypsum wallboard and related Gold Bond brand building materials to Gulf Coast construction markets, with typical operations involving the receipt, storage, packaging, and distribution of finished products via port, rail, and truck logistics; while detailed site-specific records are limited, National Gypsum historically used asbestos in certain products - especially joint compounds, cements, and acoustical materials - until the mid-to-late 1970s, meaning employees, contractors, dockworkers, and tradespeople who handled, packaged, sanded, or cleaned up these materials at National Gypsum - New Orleans, LA could have experienced asbestos exposure, and maintenance personnel working on production equipment or thermal system insulation at the site also faced potential exposure, with residual risk wherever older asbestos-containing materials remained in buildings or inventory.

The National Linen Service Corporation facility in New Orleans, Louisiana operated as a commercial laundry and linen supply plant, providing rental, cleaning, and pressing of linens, uniforms, towels, and related items for hotels, restaurants, hospitals, and industrial customers in the region; as part of a large multi-location network, operations typically involved high-capacity washers and dryers, steam tunnels, pressing equipment, and on-site boilers and steam piping for heat and sterilization. At this New Orleans, LA site, potential asbestos exposure could have occurred historically (especially before the late 1970s) from insulation and gaskets associated with boilers, steam lines, dryers, and pressing equipment, as well as from building materials common to older industrial facilities; in addition, laundry workers may have faced secondary exposure when handling soiled uniforms or rags from clients in asbestos-using industries such as shipyards, refineries, and construction. While specific, documented incidents are not cited here, these exposure pathways are recognized risks for industrial laundry operations of that era, and maintenance staff, machine operators, and sorters would have been among the worker groups with potential contact.

For National Rice Milling Company in Jennings, Louisiana: There is no additional information available on this site, but it is on the list of sites where asbestos exposure may have occurred.

National Rice Milling Company in New Orleans, LA operated as a rice processing and distribution facility serving the port economy, with typical mill operations that included receiving rough rice by rail or barge, cleaning and drying, milling and polishing, grading, bagging, warehousing, and shipping to domestic and export markets. As part of New Orleans' long-standing riverfront and Warehouse District agribusiness, the site would have employed production workers, millwrights, mechanics, and warehouse and shipping personnel to run and maintain conveyors, elevators, dryers, and other milling machinery. In the mid-20th century, rice mills commonly incorporated asbestos-containing materials for heat and fire protection - such as insulation on boilers and steam lines, gaskets and packing in pumps and valves, and some roofing, cement, and fireproofing products - so possible asbestos exposure at National Rice Milling Company could have occurred during equipment operation, maintenance, and repairs, particularly in boiler and mechanical rooms and along insulated piping. Contractors and employees disturbing worn or replaced insulation, gaskets, or other high-heat components would have faced the greatest risk of airborne fiber release, especially before modern controls and abatement practices were in place.

For National Space Technology in New Orleans, Louisiana, there is no additional information available on this site, but it is on the list of sites where asbestos exposure may have occurred.

Naval Regional Medical Hospital in New Orleans, Louisiana was a U.S. Navy medical facility that supported the readiness and healthcare needs of active-duty service members, reservists, retirees, and military families in the New Orleans, LA area, providing a range of inpatient and outpatient services, preventive medicine, and occupational health in support of local fleet and tenant commands. As with many mid-20th-century military hospitals, buildings of this type and era often incorporated asbestos-containing materials (such as pipe and boiler insulation, floor tiles, roofing, and fireproofing), so possible asbestos exposure could have occurred, particularly for maintenance and utilities personnel, contractors, and workers involved in repairs, renovations, or demolition, with incidental risks to staff and patients during disturbance of materials. Over time, Navy healthcare in the region has been consolidated into clinic-based services aligned with the area's remaining installations, but the facility's historical role was to deliver comprehensive medical care and medical-readiness support to the Navy community in New Orleans, Louisiana.

Naval Station - New Orleans in Algiers, New Orleans, Louisiana occupied a West Bank stretch of the Mississippi River and historically functioned as a Navy repair and support installation established in the early 20th century, later evolving into Naval Support Activity (NSA) New Orleans that provided administrative, logistics, warehousing, training, and port services for fleet and reserve components. Over time the base hosted a range of commands and tenants, and following Base Realignment and Closure decisions in the 2000s most Navy activities departed; by 2011 the site was largely transitioned into the Federal City complex, anchored by Marine Forces Reserve and Marine Forces North headquarters. As with many Navy facilities and ship-repair sites built or operated before the 1980s, operations at Algiers likely involved asbestos-containing materials in ship and shore-side systems, including pipe and boiler insulation, gaskets and packing, lagging, fireproofing, roofing, and flooring; personnel engaged in ship maintenance, engine and boiler work, or renovation and demolition of older buildings at Algiers, LA could have experienced potential asbestos exposure, particularly in confined machinery spaces and during disturbance of legacy materials.
