# SUPPLEMENTARY INFORMATION: 

## I. Background 

On November 12, 2001, Congress enacted Public Law 107-69, which provides for law enforcement authority within Reclamation projects and on Reclamation lands. Section 1(a) of this law requires the Secretary of the Interior to “issue regulations necessary to maintain law and order and protect persons and property within Reclamation projects and on Reclamation lands.” The Secretary of the Interior delegated this authority to the Commissioner of Reclamation. 

On April 17, 2002, Reclamation published 43 CFR part 423, Public Conduct on Bureau of Reclamation Lands and Projects (67 FR 19092, Apr. 17, 2002) as an interim final rule. In the preamble to that rule, Reclamation stated its intent to replace the interim final rule with a more comprehensive public conduct rule and set April 17, 2003, as the interim final rule's expiration date. In order to provide more time to develop the comprehensive public conduct rule, Reclamation later extended the expiration of the interim final rule to April 17, 2005 (68 FR 16214, Apr. 3, 2003), and again to April 17, 2006 (70 FR 15778, Mar. 29, 2005). 

                    On September 13, 2005, Reclamation published a proposed public conduct rule (70 FR 54214, Sep. 13, 2005) and asked the public to comment on that proposed rule. The Final Rule, 43 CFR Part 423, was published in the                     **Federal Register**                     on April 17, 2006 (71 FR 19790, Apr. 17, 2006).                 

Since that time, some members of the public and other entities have found certain provisions of the public conduct rule to be unclear. The purpose of this interim final rule is to amend the public conduct rule to clarify these provisions. A detailed discussion of these amendments follows. 

The definitions of the terms “Disorderly conduct” and “Trespass” are being removed, and the language from those definitions is being added to §§ 423.22 and 423.24, respectively, because these are criminal acts and their detailed descriptions should be explained in the applicable sections of Subpart C of this rule. This change will facilitate reference to specific acts when law enforcement officers issue citations for disorderly conduct and trespassing. 

The definition of “Vessel” is being revised to remove the statement that seaplanes, when on the water, are considered “vessels” under this part. This change will make Reclamation consistent with the U.S. Coast Guard and the majority of western States, which do not consider a seaplane a vessel when on the water. 

A definition of the term “Closed” is being added to help resolve confusion concerning the use of closures under Subpart B as opposed to special use areas under Subpart E of this rule. This definition will clarify the distinction that closures are to be used only when all public access to a particular area or location is to be prohibited. When only a specific activity such as camping is to be prohibited in a certain area, but other public access to that area is to be allowed, a special use area should be established. 

Section 423.3(a) is being revised to clarify that persons on Reclamation facilities, lands, and waterbodies must comply with Federal as well as State and local laws. 

Section 423.3(b)(2) is being revised to clarify that the restrictions of part 423 do not apply to State and local employees and agents when they are carrying out their official duties. 

In section 423.3(d), we are replacing the word “right” with “authority” because this passage refers to an authority which derives from Public Law 107-69. 

New § 423.18 is being added to coincide with the new definition of closure, and to clarify that closures are to be used only where all public access is to be prohibited in a given area. 

Section 423.21(a) is being revised to clarify that the public is responsible for awareness of all applicable laws as well as closures and special use areas when on Reclamation facilities, lands, and waterbodies. 

In § 423.21(b), the words “limitations, restrictions, closures, or special use areas” are being added to ensure public understanding that the government's ability to issue citations must not be interpreted too narrowly. 

Section 423.29(b) is being revised to clarify that Reclamation will not issue permits under Subpart D of this rule to introduce plant or animal species into Reclamation lands and waterbodies. Governmental entities may, with proper authority, introduce plant or animal species to Reclamation lands and waterbodies, but these activities are not restricted by part 423, pursuant to § 423.3(b)(3), and therefore no permits are needed. Furthermore, Reclamation has no intent to issue permits to the public for the introduction of plant or animal species. Therefore, the process of obtaining permits for these activities is inapplicable to either governmental entities or to the public. 

Section 423.34(c) is being reworded to clarify that under no circumstances can a latrine or toilet be placed or constructed at a level lower than the high water mark of a Reclamation waterbody, and to reduce the horizontal restriction from 200 yards to 150 feet from the high water mark. The 200-yard restriction was considered excessive. 

                    Sections 423.36 and 423.37 are being revised to clarify that posted restrictions                           ( print page 54978)                        and delineations on swimming and winter activities must be observed.                 

Section 423.38(h) is being removed because commercial activity on Reclamation facilities, lands, and waterbodies is more appropriately governed by 43 CFR part 429. 

Several revisions are being made to § 423.41. First, § 423.41(a) is being revised to clarify that part 423 is not intended to establish new prohibitions, restrictions, or allowances of aircraft activity on Reclamation lands or waterbodies. Rather, any rules concerning aircraft activity that were in place on April 17, 2006, when major revisions to part 423 went into effect, remain in effect as provided in § 423.64 (renumbered through this rulemaking as § 423.63). The revised language of § 423.41(a) also clarifies the ability of Authorized Officials to establish special use areas under Subpart E of part 423 to allow, restrict, or prohibit aircraft. Pilots and others should be cautioned that this amendment does not have the effect of changing the status of any Reclamation lands or waterbodies with respect to the allowance, restriction, or disallowance of aircraft activity. Rather, the change is being made to resolve confusion that resulted from the existing language of § 423.41(a). Pilots are still responsible for determining the laws, regulations, and local rules applicable to specific Reclamation lands or waterbodies before attempting landings or takeoffs. 

Section 423.41(e) of the existing rule is being removed because we have determined this provision is not necessary; any liability on behalf of aircraft pilots, owners, or passengers is dictated by State law. 

In renumbered § 423.41(e) [formerly § 423.41(f)], the words “and § 423.38” are being removed to clarify that seaplanes are not considered vessels when on the water. This change coincides with the change to the definition of “vessel” as explained above. 

Section 423.41(h) of the existing rule is being removed because commercial activity on Reclamation facilities, lands, and waterbodies is more appropriately governed by 43 CFR part 429. 

Section 423.41(i) of the existing rule is being removed because with the changes being made to § 423.41(a), the allowable times for aircraft landings and takeoffs are governed by other Federal, State, and local laws. 

Section 423.41(j) of the existing rule is being removed because with the changes being made to § 423.41(a), the language of section (j) addressing compliance with restrictions established by an Authorized Official is redundant. 

Section 423.50(a) is being revised to coincide with the change made to § 423.29(b) and the deletion of § 423.38(h) discussed above, to the effect that permits under part 423 will not be issued for the introduction of plants and animals, or for the commercial operation of vessels. The language was also revised to clarify that permits may be revoked to protect the health, safety, and security of persons, Reclamation assets, or natural or cultural resources. 

Subpart E, Special Use Areas, is being revised to make several clarifications. First, the current provisions of § 423.62 are being merged into § 423.60 to clarify that the requirements for “determination” and “documentation” are not two separate activities. 

                    Also, the current requirement in § 423.61(b) for a                     **Federal Register**                     notice in order to establish special use areas is being removed. Although Reclamation believes that in some cases,                     **Federal Register**                     notice of the establishment of, or changes to, special use areas may be desirable, that need is best determined through internal policy rather than a requirement in Federal regulations. This change will also make the requirements for establishing special use areas more consistent with the requirements for establishing closures under Subpart B of this rule.                 

An Authorized Official's ability to quickly establish a special use area under the current § 423.61(c) is being expanded to allow creation of special use areas with delayed notice in cases of safety and environmental needs, in addition to the existing specified conditions related to national, facility, employee, and public security. 

Section 423.61(d) is being revised to clarify that if the four specified conditions are met, advance notice of the designation of a special use area is not required. The existing language implied that no notice was required, but Reclamation believes the public should always be notified of the existence of special use areas. Note that satisfaction of the four conditions specified in § 423.61(d) removes the requirement for advance notice, meaning that notice may occur at any time up until the time the special use area is designated. This contrasts with the conditions of emergency or immediate need described in § 423.61(c) under which notice may be delayed for up to 30 days after the special use area is designated. 

Section 423.63 (formerly § 423.64) is being revised to clarify that rules that were already in effect on April 17, 2006 remain in effect to the extent allowed by Subpart A of part 423, and to the extent they are they are consistent with § 423.28. Reclamation wants to remind the public that the effect of § 423.63 is to recognize the validity of rules that that were already in effect on Reclamation facilities, lands, and waterbodies on April 17, 2006, the date major revisions to part 423 were implemented. Documented allowances, restrictions, and/or prohibitions that were in effect on that date generally remain in effect and are generally not removed or superseded by the rules contained in Subpart C of part 423. Reclamation encourages all parties to contact us with any questions concerning the rules that apply on Reclamation facilities, lands, and waterbodies. 

Section 423.71(b) is being revised to clarify that the described sanctions apply to violations of closures as well as to the other types of violations described. 

While each of the individual changes being made to part 423 is insufficient by itself to justify amending the rule, the total number of needed changes now warrants this amendatory rulemaking. 

## II. Determination To Make This Rule Effective Immediately 

Reclamation has determined that it is in the public interest to clarify and resolve the issues addressed in these amendments without delay. Members of the public have asked for a speedy implementation of regulations that will assist them to better understand their rights and obligations on Reclamation lands and waterbodies. Delay would result in unnecessary uncertainty. For these reasons, Reclamation has determined that for this rulemaking, notice and public procedure requirements are impractical, unnecessary, and contrary to the public interest and should be waived as allowed by 5 U.S.C. 553(b)(3)(B). Furthermore, for the reasons stated above, Reclamation has determined that good cause exists to waive the requirement of publication 30 days in advance of the effective date, as allowed by 5 U.S.C. 553(d)(3). 

Therefore, we are issuing these amendments as an interim final rule that will go into effect immediately. Following a 60-day public review period and our review of any public comments received, Reclamation expects to publish a final rule. 

## III. Procedural Matters 

### 1. Regulatory Planning and Review (E.O. 12866) 

                    This document is not a significant rule and is not subject to review by the Office of Management and Budget under                           ( print page 54979)    Executive Order 12866. This rule makes only minor amendments to the existing 43 CFR part 423 for purposes of clarification.                 

(1) This rule will not have an effect of $100 million or more on the economy. It will not adversely affect in a material way the economy, productivity, competition, jobs, the environment, public health or safety, or State, local, or tribal governments or communities. 

(2) This rule will not create a serious inconsistency or otherwise interfere with an action taken or planned by another agency. 

(3) This rule does not alter the budgetary effects or entitlements, grants, user fees, or loan programs or the rights or obligations of their recipients. 

(4) This rule does not raise novel legal or policy issues. 

### 2. Regulatory Flexibility Act 

                    The Department of the Interior certifies that this document will not have a significant economic effect on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601*et seq*.). This rule makes only minor amendments to the existing 43 CFR part 423 for purposes of clarification.                 

### 3. Small Business Regulatory Enforcement Fairness Act (SBREFA) 

This rule is not a major rule under 5 U.S.C. 804(2), the Small Business Regulatory Enforcement Fairness Act. This rule makes only minor amendments to the existing 43 CFR part 423 for purposes of clarification. 

The rule: 

(1) Does not have an annual effect on the economy of $100 million or more. 

(2) Will not cause a major increase in costs or prices for consumers, individual industries, Federal, State, or local government agencies, or geographic regions. 

(3) 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. 

### 4. Unfunded Mandates Reform Act 

                    This rule does not impose an unfunded mandate on State, local, or tribal governments or the private sector of more than $100 million per year. This rule does not have a significant or unique effect on State, local, or tribal governments or the private sector. This rule makes only minor amendments to the existing 43 CFR part 423 for purposes of clarification. A statement containing the information required by the Unfunded Mandates Reform Act (2 U.S.C. 1531*et seq.*) is not required.                 

### 5. Takings (E.O. 12630) 

In accordance with Executive Order 12630, this rule does not have significant takings implications. This rule makes only minor amendments to the existing 43 CFR part 423 for purposes of clarification. A takings implication assessment is not required. 

### 6. Federalism (E.O. 13132) 

In accordance with Executive Order 12612, this rule does not have sufficient federalism implications to warrant the preparation of a Federalism Assessment. This rule makes only minor amendments to the existing 43 CFR part 423 for purposes of clarification. A Federalism Assessment is not required. 

### 7. Civil Justice Reform (E.O. 12988) 

In accordance with Executive Order 12988, the Office of the Solicitor has determined that this rule does not unduly burden the judicial system and meets the requirements of sections 3(a) and 3(b)(2) of the Order. 

### 8. Consultation With Indian Tribes (E.O. 13175) 

Under the criteria in Executive Order 13175, we have evaluated this rule and determined that it has no potential effects on federally recognized Indian tribes. This rule recognizes tribal authorities, laws, and regulations but does not affect them. 

### 9. Paperwork Reduction Act 

This regulation does not require an information collection from 10 or more parties and a submission under the Paperwork Reduction Act is not required. An OMB form 83-I is not required. 

### 10. National Environmental Policy Act (NEPA) 

This rule does not constitute a major Federal action significantly affecting the quality of the human environment. A detailed statement under the National Environmental Policy Act of 1969 is not required. 

### 11. Information Quality Act 

In developing this rule we did not conduct or use a study, experiment, or survey requiring peer review under the Information Quality Act (Pub. L. 106-554). 

### 12. Effects on the Energy Supply (E.O. 13211) 

This rule is not a significant energy action under the definition of Executive Order 13211. A Statement of Energy Effects is not required. 

### 13. Clarity of This Regulation 

We are required by E.O. 12866 and 12988, and by the Presidential Memorandum of June 1, 1998, to write all rules in plain language. This means each rule we publish must: 

(a) Be logically organized; 

(b) Use the active voice to address readers directly; 

(c) Use clear language rather than jargon; 

(d) Be divided into short sections and sentences; and 

(e) Use lists and tables wherever possible. 

                    If you believe we have not met these requirements, please send comments to Reclamation as instructed in the                     **ADDRESSES**                     section. Please make your comments as specific as possible, referring to specific sections and how they could be improved. For example, you should tell us the numbers of the sections or paragraphs that are unclearly written, which sections or sentences are too long, the sections where you believe lists or tables would be useful, etc.                 

### 14. Public Availability of Comments 

Before including your name, address, phone number, e-mail address, or other personal identifying information in your comment, you should be aware that your entire comment—including your personal identifying information—may be made publicly available at any time. While you can ask us in your comment to withhold your personal identifying information from public review, we cannot guarantee that we will be able to do so.
