§ 700.1 - Scope.

The regulations in chapter VII of 30 CFR, consisting of parts 700 through 899, establish the procedures through which the Secretary of the Interior will implement the Surface Mining Control and Reclamation Act of 1977 (Pub. L. 95-87, 91 Stat. 445 (30 U.S.C. 1201 et. seq.)). Chapter VII is divided into 13 subchapters.

(a) Subchapter A contains introductory information intended to serve as a guide to the rest of the chapter and to the regulatory requirements and definitions generally applicable to the programs and persons covered by the Act.

(b) Subchapter B contains regulations covering the initial regulatory program which apply before the applicability of permanent program regulations to persons conducting surface coal mining and reclamation operations and other persons covered by the Act.

(c) Subchapter C sets forth regulations covering applications for and decisions on permanent State programs; the process to be followed for substituting a Federal program for an approved State program, if necessary; the process for assuming temporary Federal enforcement of an approved State program; and the process for implementing a Federal program in a State when required by the Act.

(d) Subchapter D of this chapter identifies the procedures that apply to surface coal mining and reclamation operations conducted on Federal lands rather than State or private lands and incorporates by reference the requirements of the applicable regulatory program and the inspection and enforcement requirements of subchapter L of this chapter.

(e) Subchapter E of this chapter contains regulations that apply to surface coal mining and reclamation operations conducted on Indian lands.

(f)(1) Subchapter F implements the requirements of the Act for—

(i) Designating lands which are unsuitable for all or certain types of surface coal mining operations;

(ii) Terminating designations no longer found to be appropriate; and

(iii) Prohibiting surface coal mining and reclamation operations on those lands or areas where the Act states that surface coal mining operations should not be permitted or should be permitted only after specified determinations are made.

(2) Subchapter F does not include regulations governing designation of areas unsuitable for noncoal mining under the terms of section 601 of the Act or the designation of Federal lands under the Federal lands review provisions of section 522(b) of the Act. The Bureau of Land Management of the Department of the Interior is responsible for these provisions which will be implemented when promulgated by regulations in title 43 of the Code of Federal Regulations.

(g) Subchapter G governs applications for and decisions on permits for surface coal mining and reclamation operations on non-Indian and non-Federal lands under a State or Federal program. It also governs coal exploration and permit application and decisions on permits for special categories of coal mining on non-Indian and non-Federal lands under a State or Federal program. Regulations implementing the experimental practices provision of the Act are also included in subchapter G.

(h) Subchapter J sets forth requirements for performance bonds and public liability insurance for both surface mining and underground mining activities.

(i) Subchapter K sets forth the environmental and other performance standards which apply to coal exploration and to surface coal mining and reclamation operations during the permanent regulatory program. The regulations establish the minimum requirements for operations under State and Federal programs. Performance standards applicable to special mining situations such as anthracite mines, steep slope mining, alluvial valley floors, and prime farmlands are included.

(j) Subchapter L sets forth the inspection, enforcement, and civil penalty provisions that apply to a State, Federal, or Federal lands program.

(k) Subchapter M sets forth the requirements for the training, examination, and certification of blasters.

(l) Subchapter P sets forth the provisions for protection of employees who initiate proceedings under the Act or testify in any proceedings resulting from the administration or enforcement of the Act.

(m) Subchapter R sets forth the regulations for the abandoned mine land reclamation program. These regulations include the fee collection requirements and the mechanisms for implementing the State and Federal portions of the abandoned mine land reclamation program.

(n) Subchapter S sets forth the regulations that apply to grants for mining and mineral research institutes and grants for mineral research projects.

[53 FR 44363, Nov. 2, 1988]

§ 700.11 - Applicability.

(a) Except as provided in paragraph (b) of this section, this chapter applies to all coal exploration and surface coal mining and reclamation operations, except:

(1) The extraction of coal by a landowner for his or her own noncommercial use from land owned or leased by him or her. Noncommercial use does not include the extraction of coal by one unit of an integrated company or other business or nonprofit entity which uses the coal in its own manufacturing or power plants;

(2) The extraction of 250 tons of coal or less by a person conducting a surface coal mining and reclamation operation. A person who intends to remove more than 250 tons is not exempted;

(3) The extraction of coal as an incidental part of Federal, State or local government-financed highway or other construction in accordance with part 707 of this chapter;

(4) The extraction of coal incidental to the extraction of other minerals where coal does not exceed 16 2/3 percent of the total tonnage of coal and other minerals removed for purposes of commercial use or sale in accordance with part 702 of this chapter.

(5) Coal exploration on lands subject to the requirement of 43 Cspan parts 3480-3487.

(b) This chapter does not apply to the extraction of coal for commercial purposes where the surface coal mining and reclamation operation, together with any related operations, has or will have an affected area of two acres or less. For purposes of this paragraph:

(1) Where a segment of a road is used for access or coal haulage by more than one surface coal mining operation, the entire segment shall be included in the affected area of each of those operations; provided, that two or more operations which are deemed related pursuant to paragraph (b)(2) of this section shall be considered as one operation for purposes of this paragraph.

(2) Except as provided in paragraph (b)(3) of this section, surface coal mining operations shall be deemed related if they occur within twelve months of each other, are physically related, and are under common ownership or control.

(i) Operations shall be deemed physically related if drainage from both operations flows into the same watershed at or before a point within five aerial miles of either operation.

(ii) Operations shall be deemed under common ownership or control if they are owned or controlled, directly or indirectly, by or on behalf of:

(A) The same person;

(B) Two or more persons, one of whom controls, is under common control with, or is controlled by the other; or

(C) Members of the same family and their relatives, unless it is established that there is no direct or indirect business relationship between or among them;

(iii) For purposes of this paragraph, control means: Ownership of 50 percent or more of the voting shares of, or general partnership in, an entity; any relationship which gives one person the ability in fact or law to direct what the other does; or any relationship which gives one person express or implied authority to determine the manner in which coal at different sites will be mined, handled, sold or disposed of.

(3) Notwithstanding the provisions of paragraph (b)(2) of this section, the regulatory authority may determine, in accordance with the procedures applicable to requests for determination of exemption pursuant to paragraph (c) of this section, that two or more surface coal mining operations shall not be deemed related if, considering the history and circumstances relating to the coal, its location, the operations at the sites in question, all related operations and all persons mentioned in paragraph (b)(2)(ii) of this section, the regulatory authority concludes in writing that the operations are not of the type which the Act was intended to regulate and that there is no intention on the part of such operations or persons to evade the requirements of the Act or the applicable regulatory program.

(4) The exemption provided by paragraph (b) of this section applies only to operations with an affected area of less than two acres where coal is being extracted for commercial purposes and to surface coal mining operations within that affected area incidental to such operations.

(c) The regulatory authority may on its own initiative and shall, within a reasonable time of a request from any person who intends to conduct surface coal mining operations, make a written determination whether the operation is exempt under this section. The regulatory authority shall give reasonable notice of the request to interested persons. Prior to the time a determination is made, any person may submit, and the regulatory authority shall consider, any written information relevant to the determination. A person requesting that an operation be declared exempt shall have the burden of establishing the exemption. If a written determination of exemption is reversed through subsequent administrative or judicial action, any person who, in good faith, has made a complete and accurate request for an exemption and relied upon the determination, shall not be cited for violations which occurred prior to the date of the reversal.

(d)(1) A regulatory authority may terminate its jurisdiction under the regulatory program over the reclaimed site of a completed surface coal mining and reclamation operation, or increment thereof, when:

(i) The regulatory authority determines in writing that under the initial program, all requirements imposed under subchapter B of this chapter have been successfully completed; or

(ii) The regulatory authority determines in writing that under the permanent program, all requirements imposed under the applicable regulatory program have been successfully completed or, where a performance bond was required, the regulatory authority has made a final decision in accordance with the State or Federal program counterpart to part 800 of this chapter to release the performance bond fully.

(2) Following a termination under paragraph (d)(1) of this section, the regulatory authority shall reassert jurisdiction under the regulatory program over a site if it is demonstrated that the bond release or written determination referred to in paragraph (d)(1) of this section was based upon fraud, collusion, or misrepresentation of a material fact.
