## I. Background on the Colorado Program.

                    On December 15, 1980, the Secretary of the Interior conditionally approved the Colorado program. You can find background information on the Colorado program, including the Secretary's findings, the disposition of comments, and the conditions of approval of the Colorado program in the December 15, 1980,                     **Federal Register**                     (45 FR 82173). You can also find later actions concerning Colorado's program and program amendments at 30 CFR 906.11, 906.15, 906.16, and 906.30.                

## II. Description of the Proposed Amendment

                    By letter dated May 12, 2000, Colorado sent us a proposed amendment to its program (administrative record No. CO-691) under SMCRA (30 U.S.C. 1201*et seq.*). Colorado sent the amendment in response to May 7, 1986, and June 19, 1997, letters (administrative record Nos. CO-282 and CO-686) that we sent to Colorado in accordance with 30 CFR 732.17(c); required program amendment codified at 30 CFR 906.16(d) and (e); and to include 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**                    .                

Colorado proposes to:

(1) Add, at Rule 1.04(31a), a definition of “cumulative impact area” that means the area which includes, at a minimum, the entire projected lives through bond release of: the proposed operation; all existing operation; any operation for which a permit application has been submitted; all other operations required to meet diligent development requirements for leased federal coal, for which there is actual mine development information available;

(2) Revise, at Rule 1.04(71), the definition of land use, to clarify that all of the land uses described may include land used for support facilities which are adjacent to, or are in integral part of the land use;

(3) Delete, at Rule 1.04(115a), the definition of “sediment treatment facilities and replace it with, at Rule 1.04(81a), a definition of ‘other treatment facilities’ that means any chemical treatments, such as flocculation or neutralization, or mechanical structures, such as, but not limited to, clarifiers or precipitators, that have a point source discharge and are utilized: (i) to prevent additional contributions of dissolved or suspended solids to streamflow or runoff outside the permit area; or (ii) to comply with all applicable State and Federal water-qualify laws and regulations;”

(4) Add, at Rule 1.04(86a), a definition of “permit impoundment” that means a impoundment which is approved, and if required, by other State and Federal agencies for retention as part of the post-mining land use;

(5) Add, at Rule 1.04(93a), a definition of “point of compliance” that means any geographic location at which compliance with applicable ground water quality standards established by the Water Quality Control Commission must be attained and where this compliance will be demonstrated by compliance monitoring of the groundwater or by other valid means;

(6) Revise, at Rule 1.04(115), the definition of “sedimentation pond” to clarify that it is an impoundment used as a primary sediment control structure to remove solids from water to meet water-quality standards or effluent limitations before the water leaves the permit area;

(7) Add, at Rule 1.04(137a), a definition of “temporary impoundment” that means an impoundment used during surface coal mining and reclamation operations, but not approved to remain as part of the approved post-mining land use;

(8) Revise Rule 2.05.2(1) through (6), concerning water quality standards and effluent limitations, to add references to other treatment facilities;

(11) Revise Rule 2.05.3(4)(a)(iv), concerning permit application requirements, to incorporate by reference (for sedimentation ponds or impoundments that meet or exceed the criteria of the Mine Safety and Health Administration (MSHA)), the MSHA requirements codified at 30 CFR 77.216(a), 77-216-1 and 77.216-2;

(12) Add, at Rules 2.05.3(4)(a)(v), (vi) and (vii), concerning permit application requirements, to require (1) submission of any plans that must be submitted to and approved by with the State Engineer or MSHA, (2) that all impoundments meeting the Class B or Class C criteria for dams in the Soil Conservation Service Technical Release No. 60 (TR60) comply with the requirements for impoundments that meet or exceed the size or other criteria of 30 CFR 77.216(a) (and to incorporate by reference TR60), and (3) require a stability analysis for each impoundment that either meets the Class B or Class C criteria for dams in TR60 or meets the size or other criteria of 30 CFR 77.216(a);

(13) Make editorial revisions at Rule 2.05.3(4)(b), concerning design requirements for sedimentation ponds;

(14) Revise Rule 2.05.3(8)(a)(iii), concerning permit application requirements for plans for coal mine waste and non-coal processing waste, to refer to impoundments with a capacity of 100 acre-feet rather than reservoirs with a capacity of more than 1000 acre-feet;

(15) Add Rules 2.05.3(8)(a)(v) and (vi), concerning plans for coal mine waste and non-coal processing waste, to require (1) that all impoundments meeting the Class B or Class C criteria for dams in the Soil Conservation Service TR60 comply with the requirements for impoundments that meet or exceed the size or other criteria of 30 CFR 77.216(a), and (2) require a stability analysis for each impoundment that either meets the Class B or Class C criteria for dams in TR60 or meets the size or other criteria of 30 CFR 77.216(a);

(16) Revise Rule 2.05.6(3)(b)(iv) and (iv)(A), concerning the plan for surface and ground water monitoring, to require (1) identification of points of compliance and (2) monitoring of manganese;

(17) Make editorial revisions at Rule 2.06.8(5)(b)(ii)(B), concerning underground mining activities;

                    (18) Revise Rule 2.07.3(3)(b) to refer to the National Resource Conservation                           ( print page 36100)                        Service rather than the Soil Conservation Service;                

(19) Revise Rule 2.07.3(3)(c) to clarify that written comments regarding technical revisions may be submitted within 10 days of the initial newspaper publication;

(20) Revise Rule 2.07.6(2)(c), concerning the assessment (for permit approval or denial) of probable cumulative impacts of all anticipated mining on the hydrologic balance, to add references to cumulative impact area and material damages;

(21) Revise Rule 4.05.6, concerning sedimentation ponds, to (1) apply the requirements to other treatment facilities and (2) simplify by reorganizing the section and removing certain requirements that are applicable to impoundments in general and are not specific to sedimentation ponds or other treatment facilities (these requirements are set forth at Rule 4.05.9 which is applicable to impoundments in general);

(22) Revise Rule 5.05.7, concerning discharge structures, to add a reference to other treatment facilities;

(23) Revise Rule 4.05.9, concerning impoundments, to (1) clarify and simplify by reorganizing and removing redundant requirements and (2) add, at Rules 4.05.9(2)(d), (e)(i), and (ii), (6), (8)(a), (10), and (21) requirements, concerning spillways, embankments, freeboard, and inspections, for impoundments meeting the Class B or Class C criteria for dams in the Soil Conservation Service TR60;

(24) Revise Rule 4.05.9, concerning impoundments, to add a new Rule 4.05.9(18) that (1) waives the requirement for quarterly inspections by a registered engineer, but requires annual inspections by a qualified person, for impoundments which are (a) not the primary sediment control for area, (b) located in reclaimed terrain to enhance the postmining land use, and (c) either completely incised or do not exceed 2 acre-feet in capacity and do not have embankments larger than five feet in height; and (2) requires that (a) the above waiver be approved and (b) such a waiver cannot be approved unless a written safety demonstration is submitted by a professional engineer which shows that the impoundments will not present any threat to human health and safety, or significant threat to the environment (all other impoundments-related rules are applicable and Colorado is required to field verify the safety demonstration and may rescind the waiver, for good cause if conditions change over time);

(25) Revise Rule 4.05.13(1), concerning ground water monitoring, to add requirements concerning monitoring points of compliance;

(26) Revise Rule 4.05.18, concerning stream buffer zones, to (1) require that no land within 100 feet, or greater distance if required, of a perennial stream, an intermittent stream, or an ephemeral stream with a drainage area greater than one square mile, by surface and underground coal mining operations, unless authorized, and (2) require, upon a waiver of buffer zone, Colorado to find that (a) surface coal mining operations will not cause or contribute to the violation of applicable water quality standards, (b) during and after mining, the water quantity and quality, and other environmental resources of the stream shall not be adversely affected, and, (c) if there will be a temporary or permanent stream channel diversion, the diversion will comply with Rules 4.05.3 and 4.05.4;

We will make a written summary of each meeting a part of the administrative record.                

## IV. Procedural Determinations.

### Executive Order 12630—Takings

This rule does not have takings implications. This determination is based on the analysis performed for the counterpart Federal regulations.

### Executive Order 12866—Regulatory Planning and Review

This rule is exempted from review by the Office of Management and Budget (OMB) under Executive Order 12866.

### Executive Order 12988—Civil Justice Reform

The Department of the Interior has conducted the reviews required by section 3 of Executive Order 12988 and has determined that, to the extent allowable by law, this rule meets the applicable standards of subsections (a) and (b) of that section. However, these standards are not applicable to the actual language of State regulatory programs and program amendments since each such program is drafted and promulgated by a specific State, not by OSM. Under sections 503 and 505 of SMCRA (30 U.S.C. 1253 and 1255) and the Federal regulations at 30 CFR 730.11, 732.15, and 732.17(h)(10), decisions on proposed State regulatory programs and program amendments submitted by the States must be based solely on a determination of whether the submittal is consistent with SMCRA and its implementing Federal regulations and whether the other requirements of 30 CFR Parts 730, 731, and 732 have been met.

### Executive Order 13132—Federalism

This rule does not have Federalism implications. SMCRA delineates the roles of the Federal and State governments with regard to the regulation of surface coal mining and reclamation operations. One of the purposes of SMCRA is to “establish a nationwide program to protect society and the environment from the adverse effects of surface coal mining operations.” Section 503(a)(1) of SMCRA requires that State laws regulating surface coal mining and reclamation operations be “in accordance with” the requirements of SMCRA. Section 503(a)(7) requires that State programs contain rules and regulations “consistent with” regulations issued by the Secretary pursuant to SMCRA.

### National Environmental Policy Act

Section 702(d) of SMCRA (30 U.S.C. 1292(d)) provides that a decision on a proposed State regulatory program provision does not constitute a major Federal action within the meaning of section 102(2)(C) of the National Environmental Policy Act (42 U.S.C. 4332(2)(C)). A determination has been made that such decisions are categorically excluded from the NEPA process (516 DM 8.4.A).

### Paperwork Reduction Act

                    This rule does not contain information collection requirements that require approval by  OMB under the Paperwork Reduction Act (44 U.S.C. 3507*et seq.*).                

### Regulatory Flexibility Act

                    The Department of the Interior has determined that this rule will not have  a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601*et seq.*). The State submittal that is the subject of this rule is based upon counterpart Federal regulations for which an economic analysis was prepared and certification made that such regulations would not have a significant economic effect upon a substantial number of small entities. Accordingly, this rule will ensure that existing requirements previously promulgated by OSM will be implemented by the State. In making the determination as to whether this rule would have a significant economic impact, the Department relied upon the data and assumptions for the counterpart Federal regulations.                

### Small Business Regulatory Enforcement Fairness Act

This rule is not a major rule under 5 U.S.C. 804(2), the Small Business Regulatory Enforcement Fairness Act. This rule: (a) Does not have an annual effect on the economy of $100 million; (b) Will not cause a major increase in costs or prices for consumers, individual industries, geographic regions, or Federal, State or local governmental agencies; and (c) Does not have significant adverse effects on competition, employment, investment, productivity, innovation, or the ability of U.S. based enterprises to compete with foreign-based enterprises. This determination is based upon the fact that the State submittal which is the subject of this rule is based upon counterpart Federal regulations for which an analysis was prepared and a determination made that the Federal regulation was not considered a major rule.

### Unfunded Mandates

This rule will not impose a cost of $100 million or more in any given year on any governmental entity or the private sector.
