EPA-Designated MPRSA Ocean Sites

Site boundaries of ocean sites designated by the EPA under the MPRSA. The EPA designates and manages ocean sites for certain materials permitted under the MPRSA. Locations for designated MPRSA ocean sites are selected to minimize the risk of potentially adverse impacts of the disposed material on human health and the marine environment. Designated ocean sites are published in the Code of Federal Regulations at 40 CFR 228.15. As of August 2025, the EPA’s Marine Protection Permitting Program manages 96 designated MPRSA ocean sites. The number of ocean sites may vary slightly from year to year as the EPA designates a new site or cancels (de-designates) a site that is no longer needed. All but one of the currently designated ocean sites are for dredged material permitted or authorized under the MPRSA. There is currently one EPA-designated ocean site for the disposal of fish processing wastes off American Samoa.

Point of contact: Betsy Valente, [e-mail]美国环境保护署（Environmental Protection Agency, EPA）依据《海洋保护、研究与保护区法》（Marine Protection, Research, and Sanctuaries Act, MPRSA）所指定的海洋场地边界。EPA负责指定并管理符合MPRSA许可要求的特定物料的海洋处置场地。所选MPRSA海洋场地的选址原则为最大限度降低处置物料对人类健康及海洋环境造成潜在不利影响的风险。已指定的海洋场地已收录于《联邦法规汇编》（Code of Federal Regulations, CFR）第40卷第228.15节。截至2025年8月，EPA海洋保护许可项目共管理96处MPRSA指定海洋场地。随着EPA新增场地指定或撤销不再需要的场地，海洋场地总数每年或存在小幅变动。目前除一处场地外，其余所有指定海洋场地均用于处置依据MPRSA获得许可或授权的疏浚物料。当前仅有一处由EPA指定的海洋场地，用于美属萨摩亚外海的鱼类加工废弃物处置。如需了解更多MPRSA海洋场地相关信息，请访问：https://www.epa.gov/ocean-dumping/mprsa-ocean-sites 所有坐标已转换为世界大地测量系统1984（World Geodetic System 1984, WGS 84）。注意：本地图仅用于参考用途，未为法律事务或相关事宜编制，亦不适用于此类场景。联系方式：贝琪·瓦伦蒂（Betsy Valente），电子邮箱：[e-mail]
