TITLE 31. NATURAL RESOURCES AND CONSERVATION

PART 10. TEXAS WATER DEVELOPMENT BOARD

CHAPTER 356. GROUNDWATER MANAGEMENT

The Texas Water Development Board (TWDB) proposes amendments to 31 Texas Administrative Code (TAC) Subchapters A, B, C, E, and G, more specifically §§356.10, 356.20, 356.22, 356.31 - 356.35, 356.51 - 356.57, and §§356.70 - 356.72.

BACKGROUND AND SUMMARY OF THE FACTUAL BASIS FOR THE PROPOSED AMENDMENT.

The TWDB is proposing this rulemaking primarily to modernize, update, and clarify rule language to facilitate groundwater management in the state and to clarify requirements for groundwater conservation districts. The proposed rule language adds more specificity and clarity regarding desired future condition packages, including non-relevant aquifer documentation; required elements of groundwater management plans; and brackish groundwater production zones. Additionally, the TWDB proposes adding definitions for brackish groundwater, conservation, groundwater management area, and non-relevant aquifer.

SECTION BY SECTION DISCUSSION OF PROPOSED AMENDMENTS.

31 TAC 356, Subchapter A

Section 356.10, Definitions, is proposed to be amended primarily to add the following new definitions: "brackish groundwater" in proposed §356.10(5), "conservation" in proposed §356.10(9), "groundwater management area" in proposed §356.10(15), and "non-relevant aquifer" in proposed §356.10(21). Other proposed amendments to §356.10 include correcting an error in §356.10(3) to refer to the "quantity" of water rather than the "quality" of water, renumbering the entire section to provide for new definitions and to modernize and clarify the rule language improving the readability of the rule.

31 TAC 356, Subchapter B

Sections 356.20 and 356.22 are proposed to be amended to modernize the rule language. No changes are proposed to §356.21 and that rule will not be published with this proposal.

31 TAC 356, Subchapter C

No changes are proposed to §356.30. That rule will not be published with this proposal.

Section 356.31 is proposed to be amended to update the title of the section and the due date by which desired future condition packages are due from a designated representative of each groundwater management area to the Executive Administrator of the TWDB. The proposed amendments also clarify "non-relevant" aquifer designations and required documentation submitted as part of a desired future condition package.

Section 356.32 is proposed to be amended to update the title of the section, to clarify the contents of the submission package for desired future conditions due to the TWDB, to require the submission of "non-relevant" aquifer information, and to renumber the section as appropriate.

Section 356.33 is proposed to be amended to require that a package submitting a desired future condition by the representative of a groundwater management area be signed and dated by that representative. The proposed amendments also clarify how the Executive Administrator of the TWDB will determine whether a submission package is administratively complete.

Section 356.34 is proposed to be amended to modernize the rule language.

Section 356.35 is proposed to be amended to clarify that a desired future condition package is what is declared administratively complete by the Executive Administrator.

31 TAC 356, Subchapter E

No changes are proposed to Section 356.50, and the rule will not be republished with this proposal.

Section 356.51 is proposed to be amended to modernize the rule language.

Section 356.52 is proposed to be amended to clarify that "management objectives," must correspond to a "management goal," to include proposed §356.52(a)(5) in the review of submitted management plans. Amendments to this section also include proposed §356.52(a)(7) requiring a consideration of water supply needs and water management strategies, in accordance with statute, and to modernize and re-number the rule language throughout the section.

Section 356.53 is proposed to be amended to modernize the rule language, to update the kind of information submitted to the Executive Administrator during review of a management plan, and to reflect that documentation of notice of the plan's adoption may be posted on the official website of a District. §356.53(a)(1) is amended to remove the requirement for hard-copy submissions of adopted management plans and to provide for only the submission of electronic versions of adopted management plans.

Section 356.54 is proposed to be amended to clarify that management plans are "revised" rather than "amended" when an adopted plan is not approved by the Executive Administrator.

Section 356.55 is proposed to be amended to modernize the rule language.

Section 356.56 is proposed to be amended to update the title of the section, to add new §356.56(a) clarifying the process of Executive Administrator approval of amended management plans, to provide that changes to approved management plans will be defined as "amendments" rather than "addendums," and to re-number the section.

Section 356.57 is proposed to be amended to update the rule language.

31 TAC 356 Subchapter G

Section 356.70 is proposed to be amended to update §356.70(d) to provide the TWDB the authority to amend a designated brackish groundwater production zone on its own, or by request by a district. In addition, §356.70(e) is proposed to be added to the rule requiring the TWDB to provide public notice of an amendment related to a designated brackish groundwater production zone.

Section 356.71 is proposed to be amended to update the rule language.

Section 356.72 is proposed to be amended to require districts to submit certain report information to the TWDB and to clarify and update the language.

FISCAL NOTE: COSTS TO STATE AND LOCAL GOVERNMENTS (Texas Government Code §2001.024(a)(4))

Ms. Rebecca Trevino, Chief Financial Officer, has determined that there will be no fiscal implications for state or local governments from the proposed rulemaking. For the first five years these rules are in effect, there is no expected additional cost to state or local governments resulting from their administration.

These rules are not expected to result in reductions in costs to either state or local governments and there is no change in costs with the proposed amendments to the rule because the proposed rule revisions are to modernize and clarify existing rule language. These rules are not expected to have any impact on state or local revenues. The rules do not require any increase in expenditures for state or local governments as a result of administering these rules. Additionally, there are no foreseeable implications relating to state or local governments' costs or revenue resulting from these rules.

Because these rules will not impose a cost on regulated persons, the requirement included in Texas Government Code, §2001.0045 to repeal a rule does not apply. Furthermore, the requirement in §2001.0045 does not apply because these rules are necessary for groundwater management resources of this state as authorized by the Texas Water Code and are necessary to implement legislation.

The TWDB invites public comment regarding this fiscal note. Written comments on the fiscal note may be submitted to the contact person at the address listed under the Submission of Comments section of this preamble.

PUBLIC BENEFITS AND COSTS (Texas Government Code §2001.024(a)(5))

Ms. Rebecca Trevino also has determined that for each year of the first five years the proposed rulemaking is in effect, the public will benefit from the rulemaking as the rules are necessary for groundwater management resources of this state. Ms. Rebecca Trevino also has determined that for each year of the first five years the proposed rulemaking is in effect, the rules will not impose an economic cost on persons required to comply with the proposed rule as it modernizes, updates, and clarifies rule language to facilitate groundwater management in the state and certain requirements for groundwater conservation districts.

ECONOMIC AND LOCAL EMPLOYMENT IMPACT STATEMENT (Texas Government Code §§2001.022, 2006.002); REGULATORY FLEXIBILITY ANALYSIS (Texas Government Code §2006.002)

The TWDB has determined that a local employment impact statement is not required because the proposed rule does not adversely affect a local economy in a material way for the first five years that the proposed rule is in effect because it will impose no new requirements on local economies. The TWDB also has determined that there will be no adverse economic effect on small businesses, micro-businesses, or rural communities as a result of enforcing this rulemaking. The TWDB also has determined that there is no anticipated economic cost to persons who are required to comply with the rulemaking as proposed. Therefore, no regulatory flexibility analysis is necessary.

DRAFT REGULATORY IMPACT ANALYSIS DETERMINATION (Texas Government Code §2001.0225)

The TWDB reviewed the proposed rulemaking in light of the regulatory analysis requirements of Texas Government Code §2001.0225 and determined that the rulemaking is not subject to Texas Government Code §2001.0225, because it does not meet the definition of a "major environmental rule" as defined in the Administrative Procedure Act. A "major environmental rule" is defined as a rule with the specific intent to protect the environment or reduce risks to human health from environmental exposure, a rule that may adversely affect in a material way the economy or a sector of the economy, productivity, competition, jobs, the environment, or the public health and safety of the state or a sector of the state. The intent of the rulemaking is to update and clarify existing rules that are necessary for groundwater management in the state and certain requirements for groundwater conservation districts.

Even if the proposed rule were a major environmental rule, Texas Government Code §2001.0225 still would not apply to this rulemaking because Texas Government Code §2001.0225 only applies to a major environmental rule, the result of which is to: (1) exceed a standard set by federal law, unless the rule is specifically required by state law; (2) exceed an express requirement of state law, unless the rule is specifically required by federal law; (3) exceed a requirement of a delegation agreement or contract between the state and an agency or representative of the federal government to implement a state and federal program; or (4) adopt a rule solely under the general powers of the agency instead of under a specific state law. This rulemaking does not meet any of these four applicability criteria because it: (1) does not exceed any federal law; (2) does not exceed an express requirement of state law; (3) does not exceed a requirement of a delegation agreement or contract between the state and an agency or representative of the federal government to implement a state and federal program; and (4) is not proposed solely under the general powers of the agency, but rather Texas Water Code Section 15.001 §16.0012, §16.060, §35.004, §36.001, §36.1015, §36.1071, §36.1072, Section 36.1073, §36.108, §36.1084, §36.1085, and §36.3011.Therefore, this proposed rule does not fall under any of the applicability criteria in Texas Government Code §2001.0225.

The TWDB invites public comment regarding this draft regulatory impact analysis determination. Written comments on the draft regulatory impact analysis determination may be submitted to the contact person at the address listed under the Submission of Comments section of this preamble.

TAKINGS IMPACT ASSESSMENT (Texas Government Code §2007.043)

The TWDB evaluated this proposed rule and performed an analysis of whether it constitutes a taking under Texas Government Code, Chapter 2007. The specific purpose of this rule is to update and clarify existing rules that are necessary for groundwater management in the state and certain requirements for groundwater conservation districts. The proposed rule would substantially advance this stated purpose by aligning definitions with agency and industry practice and providing greater detail for desired future condition packages and required elements of groundwater management plans.

The TWDB's analysis indicates that Texas Government Code, Chapter 2007 does not apply to this proposed rule because this is an action that is reasonably taken to fulfill an obligation mandated by state law, which is exempt under Texas Government Code §2007.003(b)(4). The TWDB is the agency charged with the delineation of groundwater management areas in order to assist with the conservation, preservation, protection and prevention of the waste of the state's groundwater resources.

Nevertheless, the TWDB further evaluated this proposed rule and performed an assessment of whether it constitutes a taking under Texas Government Code Chapter 2007. Promulgation and enforcement of this proposed rule would be neither a statutory nor a constitutional taking of private real property. Specifically, the subject proposed regulation does not affect a landowner's rights in private real property because this rulemaking does not burden, restrict, or limit the owner's right to property and reduce its value by 25% or more beyond that which would otherwise exist in the absence of the regulation. In other words, this rule updates the state's existing rules that facilitate groundwater management without burdening or restricting or limiting the owner's right to property and reducing its value by 25% or more. Therefore, the proposed rule does not constitute a taking under Texas Government Code, Chapter 2007.

GOVERNMENT GROWTH IMPACT STATEMENT (Texas Government Code §2001.0221)

The TWDB reviewed the proposed rulemaking in light of the government growth impact statement requirements of Texas Government Code §2001.0221 and has determined, for the first five years the proposed rule would be in effect, the proposed rule will not: (1) create or eliminate a government program; (2) require the creation of new employee positions or the elimination of existing employee positions; (3) require an increase or decrease in future legislative appropriations to the agency; (4) require an increase or decrease in fees paid to the agency; (5) create a new regulation; (6) expand, limit, or repeal an existing regulation; (7) increase or decrease the number of individuals subject to the rule's applicability; or (8) positively or adversely affect this state's economy.

SUBMISSION OF COMMENTS (Texas Government Code §2001.024(a)(7))

Written comments on the proposed rulemaking may be submitted by mail to Office of General Counsel, Texas Water Development Board, P.O. Box 13231, Austin, Texas 78711-3231, by email to rulescomments@twdb.texas.gov, or by fax to (512) 475-2053. Comments will be accepted until 5:00 p.m. of the 31st day following publication in the Texas Register. Include "Chapter 356" in the subject line of any comments submitted.
