Appendix II to Part 11 - Format for Data Inputs and Modifications
to the NRDAM/CME
This appendix specifies the format for data inputs and
modifications to the NRDAM/CME under § 11.41. Consult the back of
this appendix for definitions.
Starting Point for the NRDAM/CME
The NRDAM/CME begins its calculations at the point that the
released substance entered water in an area represented by its
geographic database. Any water within the geographic boundaries of
the NRDAM/CME is a “coastal or marine environment.” The authorized
official must determine all data inputs and modifications as of the
time and location that the released substance entered a coastal or
marine environment. In the case of a release that began in water in
an area within the boundaries of the NRDAM/CME, this point will be
the same as the point of the release. However, for releases that
begin on land or that begin outside the boundaries of the
NRDAM/CME, this point will not be the point of the release but
rather the point at which the released substance migrates into a
coastal or marine environment.
Required Data Inputs
Documentation of the source of the data inputs; and
Identity of Substance
For release of single substance:
Name of the substance that entered a coastal or marine
environment as it appears in Table 7.1, Volume I of the NRDAM/CME
technical document (incorporated by reference, see § 11.18).
For releases of two or more substances or a release of a mixture
of two or more substances:
Name of only one of the substances that entered a coastal or
marine environment as it appears in Table 7.1, Volume I of the
NRDAM/CME technical document.
Mass or Volume
For release of single substance:
Mass or volume of identified substance that entered a coastal or
marine environment stated in tonnes, barrels, gallons, liters,
pounds, or kilograms.
For releases of two or more substances or a release of a mixture
of two or more substances:
Mass or volume of the one identified substance (rather than
total mass) that entered a coastal or marine environment stated in
tonnes, barrels, gallons, liters, pounds, or kilograms.
Duration
Length of time over which the identified substance entered a
coastal or marine environment stated in hours.
Time
Year, month, day, and hour when the identified substance first
entered a coastal or marine environment.
Location
Latitude and longitude, stated in degrees and decimal minutes,
where the identified substance entered a coastal or marine
environment.
Winds
At least one set of data on prevailing wind conditions for each
day of the 30-day period beginning 24 hours before the identified
substance entered a coastal or marine environment. Each set must
include:
Wind velocity stated in knots or meters per second; and
Corresponding wind direction stated in the degree angle of the
wind's origin.

or sediments removed) stated in barrels, gallons, or cubic
meters.

over which the released substance was likely to have spread, stated
in terms of the northern- and southern-most latitude, and the
eastern- and western-most longitude;
One or more time frames for removal stated in terms of the
number of days and hours after the identified substance entered a
coastal or marine environment that removal began and ended; and
For each time frame, volume of the identified substance removed
(not the total volume of contaminated water or sediments removed)
stated in barrels, gallons, or cubic meters.
Closures
Documentation that the closure was ordered by an appropriate
agency as a result of the release;
Province(s) in which closure occurred; and
For beaches:
Whether the beach was Federal or State (including municipal or
county);
Number of days of closure stated by calendar month; and
Length of shoreline closed, stated in kilometers, for each month
in which closure occurred.
For fisheries and shellfish harvest areas:
Whether area closed was seaward open water, landward open water,
or structured;
Number of days of closure; and
Area closed stated in square kilometers.
For furbearer hunting or trapping areas and waterfowl hunting
areas:
Number of days of closure; and
Area closed stated in square kilometers.
Implicit Price Deflator
Quarterly implicit price deflator for the Gross National Product
(base year 1992) for the quarter in which the identified substance
entered a coastal or marine environment. [See the Survey of Current
Business, published by the U.S. Department of Commerce/Bureau of
Economic Analysis, 1441 L Street, NW, Washington, D.C., 20230,
(202) 606-9900.]
Currents
For a rectangular geographic area encompassing the area affected
by the release stated in terms of the northern- and southern-most
latitude, and the eastern- and western-most longitude:
At least one set of data concerning background (mean) current
consisting of -
An east-west (U) velocity stated in centimeters per second or
knots;
A north-south (V) velocity stated in centimeters per second or
knots; and
Latitude and longitude of the origin of the U and V velocity
components.
At least one set of data concerning tidal current at time of
flood stage (i.e., rising tide) consisting of -
An east-west (U) velocity stated in centimeters per second or
knots;
A north-south (V) velocity stated in centimeters per second or
knots; and
Latitude and longitude of the origin of the U and V velocity
components.

Definitions
Background (mean) current - net long-term current flow
(i.e., one direction only), attributable to forces such as winds,
river flow, water density, and tides, that remains when all the
oscillatory (tidal) components have been removed either
mathematically or by measurement techniques.
Landward open water - a body of water that does not
contain vegetation (e.g., wetland, seagrass, or kelp) or
invertebrate reef (e.g., coral reef) and is classified as
“landward” in Table 6.2, Volume I of the NRDAM/CME technical
document.
Province - one of the geographic areas delineated in
Table 6.1, Volume I of the NRDAM/CME technical document.
Seaward open water - a body of water that does not
contain vegetation (e.g., wetlands, seagrass, or kelp) or
invertebrate reef (e.g., coral reef) and is classified as “seaward”
in Table 6.2, Volume I of the NRDAM/CME technical document.
Structured - in an area that contains vegetation (e.g.,
wetlands, seagrass, or kelp) or invertebrate reef (e.g., coral
reef).
Tidal current - currents caused by alternating rise and
fall of the sea level due to the gravitational forces between the
earth, moon, and sun.
Tidal range - difference between the highest and lowest
height of the tide.
