Title 43 — Public Lands

Chapter 2 — United States Geological Survey

§ 31a. Findings and purpose

Statutory text

(a)

Findings

The Congress finds and declares that—

(1)

although significant progress has been made in the production of geologic maps since the establishment of the national cooperative geologic mapping program in 1992, no modern, digital, geologic map exists for approximately 75 percent of the United States;

(2)

geologic maps are the primary data base for virtually all applied and basic earth-science investigations, including—

(A)

exploration for and development of mineral, energy, and water resources;

(B)

screening and characterizing sites for toxic and nuclear waste disposal;

(C)

land use evaluation and planning for homeland and environmental protection;

(D)

earthquake hazards reduction;

(E)

identifying volcanic hazards;

(F)

design and construction of infrastructure requirements such as utility lifelines, transportation corridors, and surface-water impoundments;

(G)

reducing losses from landslides and other ground failures;

(H)

mitigating effects of coastal and stream erosion;

(I)

siting of critical facilities;

(J)

recreation and public awareness; and

(K)

basic earth-science research;

(3)

Federal agencies, State and local governments, private industry, and the general public depend on the information provided by geologic maps to determine the extent of potential environmental damage before embarking on projects that could lead to preventable, costly environmental problems or litigation;

(4)

the combined capabilities of State, Federal, and academic groups to provide geologic mapping are not sufficient to meet the present and future needs of the United States for national security, environmental protection, and energy self-sufficiency of the Nation;

(5)

States are willing to contribute 50 percent of the funding necessary to complete the mapping of the geology within the State;

(6)

the lack of proper geologic maps has led to the poor design of such structures as dams and waste-disposal facilities;

(7)

geologic maps have proven indispensable in the search for needed fossil-fuel and mineral resources;

(8)

geologic map information is required for the sustainable and balanced development of natural resources of all types, including energy, minerals, land, water, and biological resources;

(9)

advances in digital technology and geographical information system science have made geologic map databases increasingly available as decision support tools for land and resource management; and

(10)

a comprehensive nationwide program of geologic mapping of surficial and bedrock deposits is required in order to systematically build the Nation’s geologic-map data base at a pace that responds to increasing demand.

(b)

Purpose

The purpose of sections 31a to 31h of this title is to expedite the production of a geologic-map data base for the Nation, to be located within the United States Geological Survey, which can be applied to land-use management, assessment, and utilization, conservation of natural resources, groundwater management, and environmental protection and management.

“Congress finds that—

“(1)

in enacting the National Geologic Mapping Act of 1992 (43 U.S.C. 31a et seq.), Congress found, among other things, that—

“(B)

geologic maps are the primary data base for virtually all applied and basic earth-science investigations;

“(C)

Federal agencies, State and local governments, private industry, and the general public depend on the information provided by geologic maps to determine the extent of potential environmental damage before embarking on projects that could lead to preventable, costly environmental problems or litigation;
