(11) to determine, upon the written request by any operator or authorized representative of miners, specifying with reasonable particularity the grounds upon which such request is made, whether any substance normally found in a coal or other mine has potentially toxic effects in the concentrations normally found in the coal or other mine or whether any physical agents or equipment found or used in a coal or other mine has potentially hazardous effects, and shall submit such determinations to both the operators and miners as soon as possible; and

(12) for such other purposes as they deem necessary to carry out the purposes of this chapter.

(b) Responsibility for carrying out prescribed activities
Activities under this section in the field of coal or other mine health shall be carried out by the Secretary of Health and Human Services through the National Institute for Occupational Safety and Health established under the Occupational Safety and Health Act of 1970 [29 U.S.C. 651 et seq.], and activities under this section in the field of coal or other mine safety shall be carried out by the Secretary of the Interior in coordination with the Secretary.

In carrying out the provisions for research, demonstrations, experiments, studies, training, and education under this section and sections 861(b) and 952(a) of this title, the Secretary of the Interior and the Secretary of Health and Human Services in coordination with the Secretary may enter into contracts with, and make grants to, public and private agencies and organizations and individuals. No research, demonstrations, or experiments shall be carried out, contracted for, sponsored, cosponsored, or authorized under authority of this chapter, unless all information, uses, products, processes, patents, and other developments resulting from such research, demonstrations, or experiments will (with such exception and limitation, if any, as the Secretary of the Interior or the Secretary of Health and Human Services in coordination with the Secretary may find to be necessary in the public interest) be available to the general public.

(d) Prevention of diseases affecting persons working with mine products
The Secretary of Health and Human Services shall also conduct studies and research into matters involving the protection of life and the prevention of diseases in connection with persons, who although not miners, work with, or around the products of, coal or other mines in areas outside of such mines and under conditions which may adversely affect the health and well-being of such persons.

(e) Authorization of appropriations
There is authorized to be appropriated to the Secretary of the Interior such sums as may be necessary to carry out his responsibilities under this section and section 861(b) of this title at an annual rate of not to exceed $20,000,000 for the fiscal year ending June 30, 1970, $25,000,000 for the fiscal year ending June 30, 1971, and $60,000,000 for the fiscal year ending June 30, 1972, and for each succeeding fiscal year thereafter.

Such sums shall remain available until expended.

(f) Exceptions to mandatory health and safety standards for improving techniques and equipment
The Secretary is authorized to grant on a mine-by-mine basis an exception to any mandatory health or safety standard under this chapter for the purpose of permitting, under such terms and conditions as he may prescribe, accredited educational institutions the opportunity for experimenting with new and improved techniques and equipment to improve the health and safety of miners. No such exception shall be granted unless the Secretary finds that the granting of the exception will not adversely affect the health and safety of miners and publishes his findings.

(g) Grants for research and development of respiratory equipment
The Secretary of Health and Human Services is authorized to make grants to any public or private agency, institution, or organization, and operators or individuals for research and experiments to develop effective respiratory equipment.
