SUPPLEMENTARY INFORMATION: 

I. Background on the Montana Program 

II. Description of the Proposed Amendment 

III. Public Comment Procedures 

IV. Procedural Determinations 

I. Background on the Montana Program 

Section 503(a) of the Act permits a 

State to assume primacy for the 

regulation of surface coal mining and 

reclamation operations on non-Federal 

and non-Indian lands within its borders 

by demonstrating that its State program 

includes, among other things, ‘‘a State 

law which provides for the regulation of 

surface coal mining and reclamation 

operations in accordance with the 

requirements of this Act * * *; and 

rules and regulations consistent with 

regulations issued by the Secretary 

pursuant to this Act.’’ See 30 U.S.C. 

1253(a)(1) and (7). On the basis of these 

criteria, the Secretary of the Interior 

conditionally approved the Montana 

program on April 1, 1980. You can find 

background information on the Montana 

program, including the Secretary’s 

findings, the disposition of comments, 

and conditions of approval of the 

Montana program in the April 1, 1980, 

Federal Register (45 FR 21560). You can 

also find later actions concerning 

Montana’s program and program 

amendments at 30 CFR 926.15, 926.16, 

and 926.30. 

II. Description of the Proposed 

Amendment 

By letter dated July 14, 2010, Montana 

sent us a proposed amendment to its 

program (Administrative Record Docket 

ID No. OSM–2010–0010) under SMCRA 

(30 U.S.C. 1201 et seq.). Montana sent 

the amendment to include the changes 

made at its own initiative. The full text 

of the program amendment is available 

for you to read at the locations listed 

above under ADDRESSES. 

Montana proposes revisions to the 

Administrative Rules of Montana (ARM) 

at Chapter 17.24.1109 (BONDING: 

LETTERS OF CREDIT. 

Montana proposes to change a 

condition for irrevocable letters of credit 

issued by banks as collateral in order to 

correct an error in the definition. 

Specifically, in ARM 

17.24.1109(1)(e)(iii), Montana proposes 

to (1) substitute ‘‘capital stock’’ for 

‘‘shareholders equity’’ to tailor the
