exceptions are specified in the grant or cooperative agreement work plan.

All data, information, and documents funded by the Chesapeake Bay Program whether through direct
Chesapeake Bay Program funding or indirect matching funds are public information and shall be made
available to the public unless there is a grant/cooperative agreement award condition that specifies
otherwise. In addition, source data collected and processed in the creation of a deliverable shall also be
submitted when practical. If source data is submitted, it shall also be delivered in electronic format. All
outputs must have associated metadata.

Deliverable Serving us. Submission Policy

Recipients can submit deliverables directly to the Chesapeake Bay Program or provide deliverables from
their organizational data/web servers. State grant recipients shall submit non-point source BMP data using
EPA's National Environmental Information Exchange Network (NEIEN). Recipients who plan to directly
serve their grant/cooperative agreement outputs through their own data server/web site must include
relevant documentation, including access instructions, within their work plan.

Recipients intending to deliver applications to be hosted by the Chesapeake Center for Collaborative
Computing (C4) must coordinate directly with the CBP Data Center to ensure those applications are within
the C4's capacity to operate and maintain. The technology used to develop those applications must be
included in the CBP baseline technology portfolio. Recipients delivering computer applications must
participate in the CBP data center release and deployment planning boards. This requirement only applies
when client/server or web applications are submitted as part of the deliverables with the expectation that
CBP will host those applications within C4.

Locational Data Policy

The Chesapeake Bay Program adheres to the EPA's national geospatial data policy that requires consistent
use of latitude/longitude coordinates to identify the location of entities. All data, containing spatial and/or
specific geographic locations, collected or assembled under a Chesapeake Bay Program grant or
cooperative agreement or to be served on the Internet via the Chesapeake Center for Collaborative
Computing, must have latitude and longitude information, as well as datum information, for each entity.

Metadata Policy

The Chesapeake Bay Program has adopted the policy, consistent with Presidential Executive Order 12906,
that all data generated or collected using federal funds, submitted to the Chesapeake Bay Program, or
served on the Internet, shall be accompanied by metadata fully conforms to the Federal Geographic Data
Committee's requirements for metadata (https://www.fgdc.gov/metadata). Metadata created for
Chesapeake Bay Program deliverables may also be delivered to other federal Clearinghouses. Guidance
for completing compliant metadata is documented in Content Standard for Digital Geospatial Metadata.

Common Station Names Guideline

The Chesapeake Bay Program has adopted the guideline that all data generated, collected for, or submitted
to the Chesapeake Bay Program shall utilize a consistent set of common station names for identifying and
reporting monitoring station locations. It is the data provider's responsibility to comply with this guideline.

The purpose of this guideline is to create one master table of station names, to the extent possible, to
reduce confusion among cooperating agencies. The Station Names table, maintained on the Chesapeake
Bay Program website, should serve as the master list. Updates to this table that are required by data
submitters shall be coordinated with the CBP Water Quality Data Manager.

Common Data Dictionary Guideline

The Chesapeake Bay Program has adopted the guideline that all data generated, collected for, submitted
to the Chesapeake Bay Program shall utilize the CBP common data dictionary for defining all data
elements and units of measure. It is the data provider's responsibility to comply with this policy.

The purpose of this guideline is to create one data dictionary, to the extent possible, to reduce confusion
among cooperating agencies. Updates required by data submitters to the dictionary shall be coordinated
with the CBP Water Quality Data Manager.

Calendar Date Policy

The Chesapeake Bay Program has adopted the standard that all data generated, collected for, or submitted
to the Chesapeake Bay Program shall adhere to the Federal Information Processing Standard,
Representation for Calendar Date and Ordinal Date for Information Interchange (FIPS PUB 4- 1).

The standard states, "For purposes of electronic data interchange in any recorded form among U.S.
Government agencies, National Institute of Standards and Technology (NIST) highly recommends that
four-digit year elements be used". The year should encompass a two-digit century that precedes, and is
contiguous with, a four-digit year-of-century (e.g., 1999, 2000, etc.). In addition, optional two-digit year
time elements specified in ANSI X3.30-1985(RI991) should not be used for the purposes of any data
interchange among U.S. Government agencies. Therefore, it is required to report and store all dates using
four digits for the year.

Common Method Codes Guideline

The Chesapeake Bay Program has adopted the guideline that all data generated, collected for, or submitted
to the CBP shall utilize the CBP Method Codes tables. The method codes are defined in the Guide to
Using CBP Water Quality Monitorins Data. It is the data provider's responsibility to comply with this
guideline that requires the use of standardized method codes, to the extent possible, to simplify data coding
and sharing.

The methods used by monitoring agencies and analytical laboratories are critical in providing accurate
measurements. Therefore, capturing the methods is a high priority during database development.
Modifications to the CBP Method Codes shall be coordinated with the Data Center to maintain consistency
in the table contents. If CBP agencies do not have a pre-defined method code that is acceptable for the
work being conducted, the grantee/contractor should work with the funding agency to develop method
codes that suits the requirements of the work, while maintaining maximum compatibility with other CBP
codes.

Numeric Data Reporting Guideline

The Chesapeake Bay Program has adopted the guideline that all data generated, collected for, or submitted
to the Chesapeake Bay Program shall report numeric data elements at the same level of precision as that

of the original measurement. The exact precision of recorded values must be maintained. This guideline
has a significant impact on data analysis and the decisions made based on these analyses.

Values should not be zero-filled to greater precision than actually recorded. For instance, if the measured
value is 0.03, then the reported value should be 0.03 and not 0.030, which would imply precision to the
third decimal place. For values that are recorded as below or above detection, a detection flag (in a
separate data field) shall be used to identify the value as below or above the detection limit of the method,
and the value shall be reported as the detectable limit. Values should be reported as zero, only if the
measured or recorded value is zero. Values that are missing shall be reported as missing or null or nil, to
identify values that were sampled but no value was obtained. Missing, null, or nil values are different
than those that were never sampled, which should be recorded as a blank field, if they are recorded at all.
It is the responsibility of the data submitter to record in the metadata, how measurements are coded, as
well as the accuracy of the measurements.

It is important to note that some software tools used in data processing may represent the data internally
with more precision than the original measurement, and/or may round the value. For instance, even though
a value of 0.3 was entered, the value may be stored and reported as 0.299999.

ITIS Biological Nomenclature Policy

The Chesapeake Bay Program has adopted the policy that all data generated, collected for, or submitted
to the Chesapeake Bay Program shall utilize the Integrated Taxonomic Information System
(www.itis.gov) biological names for identifying and reporting species. It is the data provider's
responsibility to comply with this policy.

The purpose of this policy is to create one master table of species names, to the extent possible, to reduce
confusion among cooperating agencies. The ITIS taxonomy table, maintained on the ITIS web site, should
serve as the master list. Updates to this table that are required by data submitters shall be coordinated
with the Data Center to maintain one consistent species name list.
