TITLE: OCEAN DREDGED MATERIAL DISPOSAL SITES

Geodataset Name:       EPADRDG_JUN08
Geodataset Type:       SHAPEFILE
Geodataset Feature:    Polygon
Feature Count:         11
GENERAL DESCRIPTION:
This dataset represents Ocean Dredged Material Disposal Sites (ODMDS) designated by EPA for dredged material disposal under section 102 of the Marine Protection, Research, and Sanctuaries Act (MPRSA). EPA designated sites are to be used for ocean disposal to the extent feasible. This dataset also includes the Key West ODMDS which is technically not an EPA designated ODMDS, but was rather a one time use USACE selected site for the Key West dredging project.

Most of the dredged material disposed in the ocean is disposed at ocean 
dumping sites specifically designated by EPA for dredged material disposal 
under section 102 of the Marine Protection, Research, and Sanctuaries Act 
(MPRSA). EPA designated sites are to be used for ocean disposal to the extent 
feasible.

All ocean dumping sites are required to have a site management and 
monitoring plan (SMMP) which can be found for each individual site at:
http://www.epa.gov/region04/water/oceans/sites.html. Appropriate 
management of ocean dumping sites is aimed at assuring that disposal 
activities will not unreasonably degrade or endanger human health, welfare, 
the marine environment or economic potentialities.

Management of ocean dredged material disposal sites involves:

   1. Regulating the times, the quantity, and the physical/chemical characteristics 
      of dredged material that is dumped at the site;
   2. Establishing disposal controls, conditions, and requirements to avoid and 
      minimize potential impacts to the marine environment; and
   3. Monitoring the site environs to verify that unanticipated or significant adverse 
      effects are not occurring from past or continued use of the disposal site and 
      that permit terms are met.

The data was created to serve as base information for use in GIS systems 
for a variety of planning and analytical purposes.

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
shall not be liable for any damages suffered as a result of using,

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 received this data via email from Chris McArthur on
October 14th, 2008. When received the data was in the projection
NAD27. The layer was projected to NAD83 HARN. The fields in the table
were created by GeoPlan based on the information available at:
http://www.epa.gov/region04/water/oceans/sites.html.

- Added DESCRIPT field based on NAME
- Added FGDLAQDATE based on date received from source.
- Upcased all records in attribute table.
- Renamed file from R4_ODMDS to epadrdg_jun08
