A dome is a fully enclosed structure over the terminal, including the coal storage piles and transloading equipment. A dome can be made of aluminum panels and galvanized steel and can be an irregular shape.<ref name=":4">Geometrica, Inc., [https://www.geometrica.com/en/latestnews/coal-yards Covers For Coal Yards In Varying Shapes and Sizes].</ref><ref>Aneke, et al., [./File:2016_05_05_MA_Modified_Manuscript_NotMarked.pdf Energy Storage Technologies and Real Life Applications – A State of the Art Review], ''Applied Energy'', 179, 350–377, 2016.</ref> Non-porous fabric domes have also been used,<ref>[https://www.mrt.com/news/article/W-Va-Town-Divided-Over-Coal-Plant-Suit-7777049.php W.

'''Domes''' '''are effective:''' Because domes enclose terminal storage areas, they should contain most if not all coal dust produced through terminal activities.<ref name=":5">[./File:Notes_on_email_correspondence_between_Michelle_Team.pdf Notes on Email Correspondence between Michelle Team of LF-BJMB and Repair Lab Team Member], March 3, 2024.</ref> There is limited research demonstrating the efficacy of dome structures for dust mitigation, with most references tracing back to a single U.S. EPA contractor’s report, which does not explain key assumptions.<ref>cite</ref>

'''Domes are widely-used:''' Domes are a common technology for industrial bulk storage. Domes are used specifically for coal or petcoke storage in at least 19 locations in the U.S. and globally. Domes are also used in over 100 locations that include power plants, grain dealers, mines, cement plants, ports, and other industries which stock large quantities of dry bulk materials.<ref name=":1">Repair Lab, [./File:Wind_Fences_and_Domes_Report_Repair_Lab_2024_(corrected).pdf Coal Dust in Southeast Newport News Is a Nuisance and There Are Solutions (Corrected)], August 2024.</ref> Companies that construct domes include [https://www.geometrica.com/ Geometrica, Inc.],<ref name=":3">Geometrica, Inc., [https://www.geometrica.com/en/coalandpetcoke Coal and Pet-coke: The Largest Fuel Stockpiles Can Now Be Covered].</ref> [https://www.cstindustries.com/coal-storage-silos-manufacturer/ CST Industries],<ref>CST Industries, [./File:Covers-Bulk-Materials-Brochure.pdf CST Covers: Dry Bulk Storage Systems].</ref> [https://www.dometechnology.com/applications/coal/ Dome Technology], [https://www.safsteelstructure.com/dome-coal-storage-system/ SAFS Steel Structure], [https://www.monolithic.org/storages Monolithic Dome], [https://www.lfspaceframe.com/dome-coal-storage-system-of-zhangzhou-houshi-power-plant-7-sets/ LF-BJMB], and [https://domes.com/ World Domes (DOMTEC)].

== Safety Risks ==
Coal is combustible. Therefore, enclosed coal storage must be engineered for this risk. Domes must be constructed of non-combustible materials, surfaces where dust settles should be minimized and cladding installed underneath the internal structural elements, coal should be kept as dry as possible (sprinklers are not recommended), and the dome must be sufficiently ventilated to prevent methane accumulation.<ref name=":3" />

While risks can be managed safely, there are examples of negligence by terminal companies leading to explosions or fires at coal terminals.
