30 CFR 816.56 - What additional performance standards apply to mining activities conducted in or through an ephemeral stream?
(a)Compliance with federal, state, and tribal water quality laws and regulations.
(1) You may conduct surface mining activities in or affecting waters subject to the jurisdiction of the Clean Water Act, 33 U.S.C. 1251et seq., only if you first obtain all necessary authorizations, certifications, and permits under that law.
(b)Postmining surface drainage pattern and stream-channel configuration. If you mine through an ephemeral stream, you must construct a postmining surface drainage pattern and stream-channel configurations that are consistent with the surface drainage pattern and stream-channel configurations approved in the permit in accordance with § 780.27 of this chapter.
(c)Establishment of streamside vegetative corridors.
(1) If you mine through an ephemeral stream, you must establish a vegetative corridor at least 100 feet wide along each bank of the reconstructed stream channel. The 100-foot distance must be measured horizontally on a line perpendicular to the stream, beginning at the ordinary high water mark. The corridor must be consistent with natural vegetation patterns.
(2) When planting the streamside vegetative corridors required by paragraph (c)(1) of this section, you must -
(ii) Ensure that the species planted are consistent with the revegetation plan approved in the permit.
(iii) Include appropriate native hydrophytic vegetation, vegetation typical of floodplains, or hydrophilic vegetation characteristic of riparian areas and wetlands to the extent that the corridor contains suitable habitat for those species and the stream and the geomorphology of the area are capable of supporting vegetation of that nature.
(iv) Use native trees and shrubs when planting areas within the streamside corridor that were forested at the time of application or that would revert to forest under conditions of natural succession.
(3) Paragraphs (c)(1) and (2) of this section do not require planting of hydrophytic or hydrophilic species within those portions of streamside corridors where the stream, soils, or climate are incapable of providing the moisture or other growing conditions needed to support and sustain hydrophytic or hydrophilic species. In those situations, you must plant the corridor with appropriate native species that are consistent with the baseline information concerning natural streamside vegetation included in the permit application under § 779.19 of this chapter, unless otherwise directed by an agency responsible for implementing section 404 of the Clean Water Act, 33 U.S.C. 1344.
(4) Paragraphs (c)(1) through (3) of this section do not apply to -
(ii) Situations in which establishment of a streamside vegetative corridor comprised of native species would be incompatible with an approved postmining land use that is implemented before final bond release under §§ 800.40 through 800.43 of this chapter.
