**Flood Control Regulations, Marshall Ford Dam (Mansfield Dam and Lake**  **Travis), Colorado River, Texas**

**AGENCY :**  U.S. Army Corps of Engineers, DoD.

**ACTION :**  Final rule.

**SUMMARY :**  The U.S. Army Corps of Engineers (Corps) is amending the rules regarding use and administration of Marshall Ford Dam (Mansfield Dam and Lake Travis), Colorado River, Texas. In 1997, the Lower Colorado River Authority (LCRA) completed repayment of the federal government’s contribution for acquisition and construction costs related to Mansfield Dam. Subsequently, the United States Bureau of Reclamation (USBR) has relinquished all rights and obligations to the project. However, the U.S. Department of the Interior and the USBR are referenced as project stakeholders in the Flood Control Regulations. Amending the referenced regulations to update project ownership will eliminate the current discrepancy between the regulations and associated project documents. The Fort Worth District of the Corps and LCRA have finalized a revised water control plan for Lake Travis (Marshall Ford Dam, aka Mansfield Dam). There is no intent to publish the updated water control plan in the Federal Register . Amending the regulations to indicate that the water control plan has been superseded would eliminate the need to amend the regulations each time the water control plan is modified.

**SUPPLEMENTARY INFORMATION :**  Executive Summary

The purpose of this action is to amend the regulations to reflect changes in ownership and responsibilities of flood control management of Marshall Ford Dam (Mansfield Dam and Lake Travis) by the U.S. Army Corps of Engineers (USACE) and the Lower Colorado River Authority (LCRA) and to clarify that the published water control plan has been superseded. Specifically, 33 CFR part 208 is amended: (A) A change in project ownership. The Corps is revising 33 CFR 208.11(e) List of Projects, and 33 CFR 208.19, to indicate that the LCRA, is the responsible party for operating Marshall Ford Dam in the interest of flood control above elevation 714.

(B) Revision of the Marshall Ford Dam (Mansfield Dam and Lake Travis) water control plan in 2012.

(C) USACE intention to henceforth forego publication of the Marshall Ford Dam (Mansfield Dam and Lake Travis) water control plan in the Federal Register

.

(D) USACE and LCRA as sources for obtaining information regarding the most recently approved and therefore currently the effective water control plan. Background

Mansfield Dam was funded, planned, and built by the United States Bureau of Reclamation (USBR) from February 1937 through September 1940. The Lower Colorado River Authority (LCRA) acquired the land for the project and paid for the majority of the costs related to the hydroelectric power facilities. The USBR was the project owner while LCRA was repaying the federal government contribution to the project. LCRA completed repayment in May 1997, and the USBR relinquished all rights and obligations to the project. USBR has formally requested USACE revise the water control manual (of which the water control plan is an integral part) and any other regulatory documents accordingly.

As a result of Section 7 of the Flood Control Act of 1944, the U.S. Army Corps of Engineers (USACE) is responsible for prescribing a formal water control plan for regulation of the Lake Travis storage space allocated for flood control (elevation 681.0 to elevation 714.0). As per ER 1110–2–241, Use of Storage Allocated for Flood Control and Navigation at Non-Corps Projects (24 May 1990), paragraph 6.d.— Water Control Plan and Manual, the Corps of Engineers is responsible for developing the formal flood control regulation/water control plan, documenting the plan in a water control manual, and furnishing a copy of the manual to the project owner. A water control plan for Lake Travis was published in the Federal Register (33 CFR 208.19) in May of 1951. Subsequently, 33 CFR 208 was amended in April 1976, and again in April 1979, by revising Section 208.19 to reflect revision of the water control plan. Each of these three respective water control plans, and Section 208.11, identifies the U.S. Department of the Interior and/or the USBR as stakeholders in the project.

In 2012, based on results of a recent study, USACE—Fort Worth District and LCRA finalized a jointly supported revision of the water control plan for Lake Travis. There being no requirement for publication of the water control plan in the Federal Register , USACE plans to henceforth forego doing so. Also in 2012, USACE—Fort Worth District and LCRA agreed on a formal Letter of Understanding (LOU) and a Water Control Agreement (WCA) in accordance with ER 1110–2–241, Use of Storage Allocated for Flood Control and Navigation at Non-Corps Projects (24 May 1990). LCRA has agreed to sign the LOU and the WCA, and adopt the new water control plan, upon amendment of the CFR to indicate the last published water control plan (April 1979) has been superseded.

The Corps published the proposed rule in the Federal Register on 23 December 2013 (78 FR 77397). The Corps did not receive any comments in response to the proposed rule. Administrative Requirements Plain Language

In compliance with the principles in the President’s memorandum of June 1, 1998, (63 FR 31855) regarding plain language, this preamble is written using plain language. The use of ‘‘we’’ in this notice refers to the U.S. Army Corps of Engineers. We have also used the active voice, short sentences, and common everyday terms except for necessary technical terms. Paperwork Reduction Act

This final rule does not impose any new information collection burden under the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. Therefore, this action is not subject to the Paperwork Reduction Act. Regulatory Flexibility Act (RFA), as Amended by the Small Business Regulatory Enforcement Fairness Act of 1996 (SBREFA), 5 U.S.C. 601 et seq.

The RFA generally requires an agency to prepare a regulatory flexibilityanalysis of any rule subject to noticeand-comment rulemaking requirements under the Administrative Procedure Act or any other statute unless the agency certifies that the final rule will not have a significant economic impact on a substantial number of small entities. Small entities include small businesses, small organizations and small governmental jurisdictions.

For purposes of assessing the impacts of this final rule on small entities, a small entity is defined as: (1) A small


### 13564 Federal Register / Vol. 79, No. 47 / Tuesday, March 11, 2014 / Rules and Regulations

business based on Small Business Administration size standards; (2) a small governmental jurisdiction that is a government of a city, county, town, school district, or special district with a population of less than 50,000; or (3) asmall organization that is any not-forprofit enterprise which is independently owned and operated and is not dominant in its field.

After considering the economic impacts of this final rule on small entities, we believe that this action will not have a significant economic impact on a substantial number of small entities. The final rule is consistent with current agency practice, does not impose new substantive requirements, and therefore would not have a significant economic impact on a substantial number of small entities. Congressional Review Act

The Congressional Review Act, 5 U.S.C. 801 et seq., as amended by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a final rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the United States. We will submit a report containing this final rule and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States. This final rule is not a ‘‘major rule’’ as defined by 5 U.S.C. 804(2).
