If you would like to provide comment during the public meeting, please select ‘‘yes’’ during the online registration. The line-up of speakers will be based on your date and time of registration. FOR FURTHER INFORMATION CONTACT: Ralph Cantral, Evaluator, NOAA Office for Coastal Management by phone at (301) 233–2998 or email Ralph.Cantral@ noaa.gov. Copies of the previous evaluation findings and reserve’s management plan and site profile may be viewed and downloaded on the internet at http://coast.noaa.gov/czm/ evaluations. A copy of the evaluation notification letter and most recent progress reports may be obtained upon request by contacting Ralph Cantral. Section 312 of the Coastal Zone Management Act (CZMA) requires NOAA to conduct periodic evaluations of federally approved state coastal programs and national estuarine research reserves. The process includes one or more public meetings, consideration of written public comments, and consultations with interested Federal, state, and local agencies and members of the public. For the evaluation of the Lake Superior National Estuarine Research Reserve, NOAA will consider the extent to which the state has met the national objectives, adhered to its management plan approved by the Secretary of Commerce, and adhered to the terms of financial assistance under the Coastal Zone Management Act. When the evaluation is completed, NOAA’s Office for Coastal Management will place a notice in the Federal Register announcing the availability of the Final Evaluation Findings. jbell on DSKJLSW7X2PROD with NOTICES SUPPLEMENTARY INFORMATION: Keelin Kuipers, Deputy Director, Office for Coastal Management, National Ocean Service, National Oceanic and Atmospheric Administration.

ACTION: Notice of upcoming changes. AGENCY: The National Geodetic Survey (NGS) is in the process of modernizing the National Spatial Reference System (NSRS) and plans to replace all three North American Datum of 1983 (NAD 83) frames and all vertical datums, including the North American Vertical Datum of 1988 (NAVD 88), with four new terrestrial reference frames and one new geopotential datum to which all geodetic coordinates and derived coordinates within the NSRS will be referenced. The new reference frames will rely primarily on Global Navigation Satellite Systems (GNSS), such as the Global Positioning System (GPS), as well as on a gravimetric geoid model resulting from the Gravity for the Redefinition of the American Vertical Datum (GRAV–D) Project. The modernized NSRS will be easier to access and maintain than the existing NSRS, which relies on physical survey marks that deteriorate over time and will result in new, more accurate, timetagged geodetic coordinates (i.e., latitude, longitude, ellipsoid height, orthometric height, acceleration of gravity, deflections of the vertical, and others) at all geodetic control points within the NSRS. Additionally, coordinates will be estimated within these frames and datum at five-year reference epochs from the time-tagged coordinates, beginning with 2020.00. Initial completion and rollout of the NSRS modernization is expected to occur between 2022 and 2025, with additional support tools and services rolled out in subsequent years. DATES: The modernization of the NSRS will occur between 2022 and 2025, with the release of additional tools and services occurring between 3 and 5 years later.

The modernization of the NSRS is designed to improve the accuracy of federal geodetic control. For over 200 years, NGS and its predecessor agencies, dating back to the founding of the Survey of the Coast in 1807, have been the stewards of the geodetic infrastructure—the NSRS—of the United States. As technology and scientific knowledge advance, NGS occasionally modernizes the NSRS. This announcement reflects part of the latest modernization effort. The last significant modernization of the NSRS resulted in the creation of the original North American Datum of 1983 (54 FR 25318) and the North American Vertical Datum of 1988 (58 FR 34245). These datums were defined before the widespread use of GPS and GNSS and were determined using classical geodetic measurement techniques. Over the years, minor corrections to and expansion of the NSRS occurred; however, no significant update was possible until now. Through modern geodetic surveying technology, extensive data collection initiatives, and advances in scientific knowledge, a more accurate, modern NSRS is possible. The new frames and datum shall be known as the ‘‘North American Terrestrial Reference Frame of 2022,’’ the ‘‘Pacific Terrestrial Reference Frame of 2022,’’ the ‘‘Caribbean Terrestrial Reference Frame of 2022,’’ the ‘‘Mariana Terrestrial Reference Frame of 2022,’’ and the ‘‘North American-Pacific Geopotential Datum of 2022;’’ and may be referred to as ‘‘NATRF2022,’’ ‘‘PATRF2022,’’ ‘‘CATRF2022,’’ ‘‘MATRF2022,’’ and ‘‘NAPGD2022,’’ respectively.

Upcoming Changes to the National Spatial Reference System (NSRS)

Ocean Service (NOS), National Oceanic and Atmospheric Administration 
(NOAA), Department of Commerce (DOC).

ACTION: Notice of upcoming changes.

SUMMARY: The National Geodetic Survey (NGS) is in the process of 
modernizing the National Spatial Reference System (NSRS) and plans to 
replace all three North American Datum of 1983 (NAD 83) frames and all 
vertical datums, including the North American Vertical Datum of 1988 
(NAVD 88), with four new terrestrial reference frames and one new 
geopotential datum to which all geodetic coordinates and derived 
coordinates within the NSRS will be referenced. The new reference 
frames will rely primarily on Global Navigation Satellite Systems 
(GNSS), such as the Global Positioning System (GPS), as well as on a 
gravimetric geoid model resulting from the Gravity for the Redefinition 
of the American Vertical Datum (GRAV-D) Project. The modernized NSRS 
will be easier to access and maintain than the existing NSRS, which 
relies on physical survey marks that deteriorate over time and will 
result in new, more accurate, time-tagged geodetic coordinates (i.e., 
latitude, longitude, ellipsoid height, orthometric height, acceleration 
of gravity, deflections of the vertical, and others) at all geodetic 
control points within the NSRS. Additionally, coordinates will be 
estimated within these frames and datum at five-year reference epochs 
from the time-tagged coordinates, beginning with 2020.00. Initial 
completion and rollout of the NSRS modernization is expected to occur 
between 2022 and 2025, with additional support tools and services 
rolled out in subsequent years.

SUPPLEMENTARY INFORMATION: The modernization of the NSRS is designed to 
improve the accuracy of federal geodetic control. For over 200 years, 
NGS and its predecessor agencies, dating back to the founding of the 
Survey of the Coast in 1807, have been the stewards of the geodetic 
infrastructure--the NSRS--of the United States. As technology and 
scientific knowledge advance, NGS occasionally modernizes the NSRS. 
This announcement reflects part of the latest modernization effort.
    The last significant modernization of the NSRS resulted in the 
creation of the original North American Datum of 1983 (54 FR 25318) and 
the North American Vertical Datum of 1988 (58 FR 34245). These datums 
were defined before the widespread use of GPS and GNSS and were 
determined using classical geodetic measurement techniques. Over the 
years, minor corrections to and expansion of the NSRS occurred; 
however, no significant update was possible until now. Through modern 
geodetic surveying technology, extensive data collection initiatives, 
and advances in scientific knowledge, a more accurate, modern NSRS is 
possible. The new frames and datum shall be known as the ``North 
American Terrestrial Reference Frame of 2022,'' the ``Pacific 
Terrestrial Reference Frame of 2022,'' the ``Caribbean Terrestrial 
Reference Frame of 2022,'' the ``Mariana Terrestrial Reference Frame of 
2022,'' and the ``North American-Pacific Geopotential Datum of 2022;'' 
and may be referred to as ``NATRF2022,'' ``PATRF2022,'' ``CATRF2022,'' 
``MATRF2022,'' and ``NAPGD2022,'' respectively. In order to accustom 
users to a time-dependent NSRS, NGS will also be estimating, and 
providing to the public, coordinates on geodetic control points at 
five-year reference epochs.
