Geodataset Type:       SHAPEFILE
Geodataset Feature:    Polygon
Feature Count:         10
GENERAL DESCRIPTION:
This dataset represents Ocean Dredged Material Disposal Sites (ODMDS) designated by the EPA for dredged material disposal under section 102 of the Marine Protection, Research, and Sanctuaries Act (MPRSA). In the United States, uncontaminated dredged material is the primary material disposed into the ocean today. Dredged material is sediment excavated or otherwise removed from the bottoms of the navigable waters of the United States to maintain navigation channels and docks. In October 1972, Congress enacted the Marine Protection, Research and Sanctuaries Act (MPRSA), sometimes referred to as the Ocean Dumping Act, declaring that it is the policy of the United States to regulate the dumping of all materials which would adversely affect human health, welfare or amenities, or the marine environment, ecological systems or economic potentialities. EPA is responsible for designating and managing ocean dumping sites under the Marine Protection, Research and Sanctuaries Act (MPRSA).

Ocean Disposal Sites:
EPA is responsible for designating and managing ocean dumping sites under the
Marine Protection, Research and Sanctuaries Act (MPRSA). All but one of the
currently designated ocean sites are for disposal of dredged material permitted or
authorized under the MPRSA. Many of these ocean disposal sites are located
offshore of major ports and harbors nationwide. Designated ocean disposal sites are
selected to minimize the risk of potentially adverse impacts of the disposed material
on human health and the marine environment.

As of March 2018, EPA s Ocean Dumping Program manages 99 designated ocean
disposal sites. The number of ocean disposal sites may vary slightly from year to
year as EPA designates a new site or cancels (or de-designates) a site that is no
longer needed. 


Ocean Disposal Site Management and Monitoring Plans:
All designated sites are required to have a site management and monitoring plan
(SMMP). For dredged material, USACE is responsible for developing, and providing
an opportunity for public comment on, an SMMP for each ocean dredged material
disposal site. Each SMMP includes the following, but may not be limited to:
- a baseline assessment of site conditions;
- a program for monitoring the site;
- special management conditions or practices to be implemented at each site that 
  are necessary for protection of the environment;
- consideration of the quantity of disposed materials, and the presence, nature and
  bioavailability of the contaminants in the material; 
- consideration of the anticipated long term use of the site; and 
- a schedule for review and revision of the SMMP.

Management of ocean disposal sites ensures that disposal activities will not
unreasonably degrade or endanger human health, welfare, the marine environment
or economic potentialities. Management of the ocean disposal sites involves:
- regulating the times, quantity and physical/chemical characteristics of disposed
  material;
- establishing disposal controls, conditions and requirements to avoid and minimize
  potential impacts to the marine environment; and
- monitoring the site and surrounding environment to verify that unanticipated or
  significant adverse effects are not occurring from past or continued use of the
  ocean disposal site and that terms of the MPRSA permit are met.

This dataset represents locations of ocean disposal sites designated under the MPRSA.

The Florida Geographic Data Library is a collection of Geospatial Data
compiled by the University of Florida GeoPlan Center with support from
the Florida Department of Transportation. GIS data available in FGDL is
collected from various state, federal, and other agencies (data sources)
who are data stewards, producers, or publishers. The data available in
FGDL may not be the most current version of the data offered by the
data source. University of Florida GeoPlan Center makes no guarantees
about the currentness of the data and suggests that data users check
with the data source to see if more recent versions of the data exist.

Furthermore, the GIS data available in the FGDL are provided 'as is'.
The University of Florida GeoPlan Center makes no warranties, guaranties
or representations as to the truth, accuracy or completeness of the data
provided by the data sources. The University of Florida GeoPlan Center
makes no representations or warranties about the quality or suitability
of the materials, either expressly or implied, including but not limited
to any implied warranties of merchantability, fitness for a particular
purpose, or non-infringement. The University of Florida GeoPlan Center

A note about data scale: 

Scale is an important factor in data usage.  Certain scale datasets
are not suitable for some project, analysis, or modeling purposes.
Please be sure you are using the best available data. 

1:24000 scale datasets are recommended for projects that are at the
county level.
1:24000 data should NOT be used for high accuracy base mapping such
as property parcel boundaries.
1:100000 scale datasets are recommended for projects that are at the
multi-county or regional level.
1:125000 scale datasets are recommended for projects that are at the
regional or state level or larger.

Vector datasets with no defined scale or accuracy should be
considered suspect. Make sure you are familiar with your data
before using it for projects or analysis. Every effort has been
made to supply the user with data documentation. For additional
information, see the References section and the Data Source Contact
section of this documentation. For more information regarding
scale and accuracy, see our webpage at:

DATA LINEAGE SUMMARY:
The GeoPlan Center downloaded the Ocean Dredged Material Disposal 
Sites dataset from the Ocean Disposal Map on August 10th, 2018 from
https://www.epa.gov/ocean-dumping/ocean-disposal-map. A selection of 
all 10 sites located off the coast of Florida was created on the webmap 
and then downloaded as a geojson layer. The original data was named 
feature.geojson. The layer was exported to shapefile and renamed
epadedg_aug18. When downloaded, the data was in the WGS84 
coordinate system and was later reprojected to FGDL Albers.

The following fields were removed from the table:
GlobalID
Shape_Leng
Shape_Area
Shape_Length
Shape_Area2
Shape_Length_2 

The following fields were added to the table:
DESCRIPT field based on NAME
FGDLAQDATE based on date received from source.

All records in the attribute table were upcased.
The layer was renamed epadrdg_aug18 

--------------------------------------------------------------------
Please Note:
In the previous layer, epadrdg_sep12, the Pensacola Nearshore Site was 
not included in the dataset received by GeoPlan based on the following 
information: "The Pensacola Nearshore Site has never been used and there 
is no foreseeable use of the site in the future. The EPA is planning on de-
designating it. Which is why the polygon has not been included in this layer." 
Christopher J. McArthur, P.E. (20120910).

With this update, epadrdg_aug18, the Pensacola Nearshore Site was included 
in the download, however the site is still planned for de-designation sometime 
in the future based on information provided by Gary Collins, Ocean Dumping
Coordinator, R4 (20180816).
