Section 8 (k) of the OCS Lands Act (OCSLA), as amended by Public Law 103-426 (enacted in 1994), gives BOEM the authority to negotiate an agreement for the use of OCS sand, gravel, and shell resources for use in: (1) a project for shore protection, beach restoration, or coastal restoration undertaken by a Federal, State, or local government agency; or (2) for use in a construction project funded in whole or in part by, or authorized by, the Federal government. This dataset is a collection of active, completed, expired, and proposed lease areas under BOEM's purview. Attribution consists of OCS lease number, state, project ID, volume of material allocated, borrow area ID, leases status, and administrative chronology of the lease term (e.g. execution and expiration dates).

The purpose of this dataset is to reflect the current status and spatial extent of non-energy marine mineral leasing activity on the OCS, which is a critical component of the BOEM's comprehensive resource management and stewardship role. The BOEM uses these data to manage OCS marine mineral (sediment) resources, reduce or avoid potential conflicts with other ocean uses (e.g. fishing, shipping, energy, submerged infrastructure, etc.), and preserve sensitive habitat and cultural resources. The BOEM encourages its partners, stakeholders, and all ocean users to consider these data during the planning phases of ocean resource use or conservation projects. The most current version of OCS marine mineral lease area data can be downloaded via the Marine Minerals Information System (MMIS) viewer at https://mmis.boem.gov.

The spatial and tabular data presented in this dataset were identified by the Bureau of Ocean Energy Management (BOEM) Marine Minerals Program (MMP) for the MMIS project as being critical for MMP's decision making and management responsibilities of Federal Outer Continental Shelf (OCS) mineral exploration and Federal non-energy sand/gravel lease activities. The spatial extents of each lease area in the OCS were retrieved directly from BOEM in the form of shapefiles, spreadsheets, and from Negotiated Non-Competitive Leases or Memorandum of Agreements. Boundary points with coordinates found in spreadsheets or lease documents were mapped in ESRI's ArcMap and exported to a shapefile in the corresponding lease project folder. If projection information was not noted in the source data, an informed decision was made based on the state plane and UTM zones closest to the area. Next, a master layer was created in the MMIS geodatabase data model to house all lease area polygons in a single feature class (reprojected into the NAD83 geodetic reference system). A list of attributes was developed using several sources provided by BOEM, the Army Corps of Engineers, and localities. Attribute data were collected from lease documents, post construction reports, survey reports, and survey data. Next, the disparate lease area shapefiles and their attribute data were loaded into the MMIS Lease Areas feature class. For increased accessibility, each lease area polygon was linked to the corresponding PDF lease document(s). For specific process information regarding acquisition, please reference the individual lease documents.

Conceptual consistency: adherence to rules of the conceptual schema
The MMIS data model utilizes a hierarchical structure where an ESRI enterprise geodatabase represents the top tier, and feature datasets and raster catalogs are the secondary tiers which contain groupings of similar data layers. These individual data layers were identified by MMP as important, and they make up the bottom tier. Most individual vector layers and tables are collections of data from multiple sources and across multiple dates. Extensive research went into the construction of (1) the hierarchical groupings of data (primarily by subject matter and file format) and (2) technical aspects of the data model. Data within the geodatabase was consolidated to reduce redundancy, resulting in several stand-alone tables. Relationship classes utilizing global IDs were built between vector layers and stand-alone tables in order to link disparate data. The entire MMIS data model was originally constructed using ESRI ArcGIS Diagrammer, a tool that creates and edits a geodatabase schema. The resulting geodatabase structure, data, and relationship classes were reviewed thoroughly by multiple individuals using ESRI Geodatabase Diagrammer Add-In, ESRI ArcGIS, and Microsoft Visio. ESRI Geodatabase Diagrammer Add-In creates a detailed break-down of the geodatabase and a Visio data model poster.

Refer to "Completeness Omission" Report

Completeness omission: data absent from the dataset, as described by the scope
The spatial data and attribute tables loaded into the MMIS data model are believed to be complete, in regards to maintaining each data layer/table after retrieving it from its source. Please refer to the scientific reports, as well as BOEM MMP Leases, negotiated agreements, Memoranda of Agreements, and project completion reports, for discussions of the results on the corresponding source data. Most individual vector layers and tables in the MMIS data model are collections of data from multiple sources and across multiple dates. Most likely, these MMIS layers/tables will continue to have more data loaded in the future, therefore expanding upon the list of sources and dates. Additionally, the Pacific Outer Continental Shelf (OCS) and Alaska OCS regions may eventually be added to the data model, aside from the Atlantic and Gulf of Mexico OCS regions.

Quantitative attribute accuracy: accuracy of quantitative attributes
Please refer to the scientific reports, as well as Bureau of Ocean Energy Management (BOEM) Marine Minerals Program (MMP) Leases, negotiated agreements, cooperative agreements, Memoranda of Agreements, and project completion reports, for accuracy statements on the corresponding source data. These documents are referenced in the attribute tables, where appropriate. In regards to attribute assignment in the Marine Minerals Information Systems (MMIS) data model, every effort was made to load source data into MMIS without error or modification. Some attributes contain domain restrictions in an effort to standardize the field entries and to decrease potential inconsistent entries (e.g. spelling, grammar, typographical errors, and subject matter) in the attribute.

Federal Outer Continental Shelf (OCS) Sand and Gravel Borrow Areas (Lease Areas) delineate areas on the OCS where Negotiated Non-Competitive Lease or Memoranda of Agreement (MOA) were, are, or may be in place between the Department of the Interior (DOI), acting through the Bureau of Ocean Energy Management (BOEM), and another Federal agency, or between BOEM, a State or local government agency and/or another Federal agency (such as the U.S. Army Corps of Engineers) for use of sediment deposits found at or below the surface of the seabed on the OCS. Active, Complete, and Expired polygons were created from coordinates in Lease Area Agreements. Proposed Lease Areas are still under review and will be updated as new information is available.
