TITLE 30.ENVIRONMENTAL QUALITY

Part 1. TEXAS COMMISSION ON ENVIRONMENTAL QUALITY

Chapter 330. MUNICIPAL SOLID WASTE

The Texas Commission on Environmental Quality (commission) adopts amendments to §§330.2, 330.3, 330.14, 330.51, 330.53, 330.56, 330.64, 330.230, 330.231, 330.235, 330.238, 330.242, 330.303 - 330.305, 330.415, and 330.416.

Sections 330.3, 330.14, 330.53, 330.64, 330.230, 330.231, 330.235, 330.303 - 330.305, and 330.415 are adopted without changes to the proposed text and will not be republished.

BACKGROUND AND SUMMARY OF THE FACTUAL BASIS FOR THE ADOPTED RULES

Senate Bill (SB) 405, 77th Legislature, established the Texas Board of Professional Geoscientists and the regulation of professional geoscientists. The Texas Geoscience Practice Act (the Act) requires that a person may not take responsible charge of a geoscientific report or a geoscientific portion of a report required by state agency rule unless the person is licensed through the Texas Board of Professional Geoscientists. The primary purpose of the amendments is to establish regulations for the public practice of geoscience in conformance with the Act by requiring a person who prepares and submits geoscientific information to the commission to be a licensed professional geoscientist. The Act also allows certain specified engineers to publicly practice geoscience in conformance with the Act. According to the bill analysis prepared at the time of passage, the ultimate purpose of the Act was public safety through the public registration of the practice of geoscience.

SECTION BY SECTION DISCUSSION

Adopted §330.2, Definitions, amends the introductory paragraph by deleting the word "shall" and the phrase "unless the context clearly indicates otherwise." The definition of licensed professional geoscientist is added as new paragraph (67). The definition of qualified groundwater scientist is renumbered as paragraph (107) and revised to replace "scientist or engineer" with "licensed geoscientist or licensed engineer." The definition of special waste is renumbered as paragraph (135) and revised to update citations. The definitions of commission, EPA, executive director, person, RCRA, and SWDA are deleted because they are defined in 30 TAC §3.2, concerning Definitions, and TWC and TACB are deleted because they are no longer used. The definitions of shall and should are deleted because the Legislative Council's Drafting Manual discusses the use of shall and certain other words for the purpose of drafting regulatory requirements or prohibitions or authorizing certain powers. The subsequent paragraphs are renumbered accordingly. Administrative changes are made in paragraphs (8), (72), (135), and (137) from proposal to correct punctuation and typographical errors.

The commission adopts several revisions to §330.3, Applicability, including the addition of acronyms (e.g., "MSW" in subsections (a) and (h) and "MSWLFs" in subsection (b)), and correction of references in subsections (c) and (e) - (g). In subsection (f), a change is adopted to indicate that a professional engineer must be licensed to practice in Texas, rather than being registered to practice.

Adopted §330.14, Arid Exemption Process, amends paragraphs (8) and (9) by eliminating the phrase "where appropriate" because the sealing of work done for the public by licensed professional geoscientists or engineers will always be appropriate. The term "groundwater scientist" is substituted for "groundwater professional" in paragraph (9). Adopted §330.14 also includes several administrative formatting corrections (e.g., correcting the name of the agency from "Texas Water Commission" to "Texas Commission on Environmental Quality").

Adopted §330.51(d), Permit Application for Municipal Solid Waste Facilities, makes the legal citation to the Act and to the Engineering Practice Act. Subsection (d)(1) states the responsibilities of the responsible engineer more concisely and corrects the section number and title of the citation in the Texas Administrative Code governing the use of engineers' seals. The commission adopts new subsection (d)(2) which requires the responsible licensed professional geoscientist to seal, sign, and date applicable items as required by the Act and in accordance with any rules subsequently adopted by the Texas Board of Professional Geoscientists concerning geoscientists' seals. Previously existing subsection (d)(2) is renumbered as subsection (d)(3). An administrative change is made in subsection (a)(2) from proposal to delete a cross-reference title.

The commission adopts amended §330.53(b)(11)(A) to simplify the double preposition. In addition, the commission adopts several administrative revisions, including correction of the statutory citation to the Texas Health and Safety Code, addition of acronyms, addition of introductory clauses for grammatical clarity, and correction of rule references to 30 TAC Chapter 301, concerning Levee Improvement Districts, District Plans of Reclamation, and Levees and Other Improvements.

The commission adopts revisions to §330.56, Attachments to the Site Development Plan, which involve correcting typographical errors and acronyms, rearranging wording and rewording to provide a more accurate description (e.g., replacing "after-level" with "after-equilibrium" in subsection (d)(5)(C)(i)), and correcting rule references (e.g., changing the reference from §330.200 to §330.241 in subsection (e)(6) - (8) and other rule reference corrections in subsection (k)). Administrative changes are made in subsections (d) and (n) from proposal to correct formatting and typographical errors.

Adopted §330.64, Additional Standard Permit Conditions for Municipal Solid Waste Facilities, requires that all revised drawings prepared by a licensed professional engineer or a licensed professional geoscientist shall be signed and sealed in accordance with the Act. The commission adopts a streamlining measure by deleting existing §330.64(a), because the permit or permit amendment is based on earlier submissions, and the post-permit issuance or post-permit amendment issuance versions of the site development plan are considered to be unnecessary. The remaining subsections are relettered to account for this deletion. Other adopted revisions to §330.64 are the addition of acronyms and the term "executive director" to replace outdated references and streamlining the rule language in §330.64(b) to refer to the application requirements of §330.51(e) instead of repeating those requirements in relettered subsection (b). The commission also adopts adding requirements for geoscientific plans and reports to relettered subsection (b), with similar signing and sealing requirements for geoscientists as are currently required for engineers.

Adopted §330.230, Applicability, corrects rule references and deletes obsolete language. In subsection (a), the commission adds the statement, "Owners and operators of MSWLF units shall comply with the groundwater monitoring requirements of this subchapter." This statement retains the requirement to comply with groundwater monitoring requirements which had been specified in previously existing subsections (c) and (d) which are now deleted.

Adopted §330.231(e), Groundwater Monitoring Systems, substitutes "must" for "shall" as discussed previously in this preamble and deletes unneeded language in references.

Adopted §330.235, Assessment Monitoring Program, makes acronym additions and nonsubstantive corrections to rule language and references.

Adopted §330.238, Implementation of the Corrective Action Program, corrects rule references and makes nonsubstantive changes to rule language. Administrative changes are made in subsection (e) from proposal to correct formatting errors.

Adopted §330.242(a), Monitor-Well Construction Specifications, removes an unnecessary hyphen between "solid" and "waste." Other nonsubstantive changes to rule language are adopted. In subsection (a)(1)(A) and (D), the term "licensed professional geoscientist" is substituted for "qualified geologist." The commission adopts a rule reference correction in subsection (g) relating to plugging and abandonment of monitoring wells. An administrative change is made in subsection (a)(2)(A) from proposal to spell out an acronym.

Adopted §330.303(b), Fault Areas, replaces the demonstrative adjective "such" with specific references to studies or conditions of differential subsidence or faulting; replaces "geologist" with "licensed professional geoscientist"; and adds "licensed" before "professional engineer." Other revisions to §330.303(b) are minor editorial revisions.

Adopted §330.304, Seismic Impact Zones, and adopted §330.305, Unstable Areas, substitute "must" for "shall" as discussed previously in this preamble.

Adopted §330.415(c), Additional Requirements for Municipal Solid Waste Mining Facilities, replaces the phrase "a Registered Professional Engineer" with "the licensed professional engineer"; replaces an indefinite article with the definite article; and requires that all revised geological drawings be signed and sealed by the licensed professional geoscientist responsible for their preparation and included in the loose-leaf binder.

Adopted §330.416(f), Registration Application Preparation, corrects the use of the demonstrative pronoun by substituting "that" for "which" to introduce the restrictive clause describing the soil boring plan; and changes a future tense to present tense. The phrases "soil boring plan" and "site development plan" are lowercased throughout the section. In subsections (a) and (m)(1), the term "registered" is replaced by "licensed" before "professional engineer." Adopted subsection (m) recognizes the agency accepted use of "groundwater" as a single word; inserts four necessary commas; lowercases the phrase "unified soil classification"; replaces the demonstrative pronoun introducing a restrictive clause by a conjunction; replaces a comma with a semicolon; and substitutes the word "licensed" for "registered" before "professional engineer." Administrative changes are made in subsections (h) and (m) from proposal to correct formatting and typographical errors.

FINAL REGULATORY IMPACT ANALYSIS DETERMINATION

The commission reviewed the adopted rulemaking in light of the regulatory analysis requirements of Texas Government Code, §2001.0225, and determined that the rulemaking is not subject to §2001.0225 because it does not meet the criteria for a "major environmental rule" as defined in that statute.

A "major environmental rule" means a rule, the specific intent of which, is to protect the environment or reduce risks to human health from environmental exposure and that may adversely affect in a material way the economy, 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 specific intent of the adopted rules is to establish regulations allowing for the public practice of geoscience in agency procedures in conformance with the Act. The Act requires that a person may not take responsible charge of a geoscientific report or a geoscientific portion of a report required by a state agency rule unless the person is licensed through the Texas Board of Professional Geoscientists. The Act also allows certain specified engineers to publicly practice geoscience in conformance with the Act. The adopted rules are not specifically intended to protect the environment or reduce risks to human health. The adopted rules are intended to establish procedures to require that specific reports and necessary data submitted to the commission be produced, signed, sealed, and dated by licensed professional geoscientists who have obtained their licenses through the Texas Board of Professional Geoscientists, and to make other corrections to the rules. Therefore, it is not anticipated that the adopted rules will adversely affect in a material way the economy, 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 commission concludes that these adopted rules do not meet the definition of major environmental rule.

Furthermore, even if the adopted rulemaking did meet the definition of a major environmental rule, the amendments are not subject to Texas Government Code, §2001.0225, because they do not accomplish any of the four results specified in §2001.0225(a). Section 2001.0225(a) applies to a rule adopted by an agency, 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.

In this case, the adopted amendments to Chapter 330 do not meet any of these requirements. First, there are no applicable federal standards that these rules would address. Second, the adopted rules do not exceed an express requirement of state law. Third, there is no delegation agreement that would be exceeded by these adopted rules. Fourth, the commission adopts these rules to allow for the public practice of geoscience in agency procedures in conformance with the Act. Therefore, the commission does not adopt the rules solely under the commission's general powers.

TAKINGS IMPACT ASSESSMENT

The commission evaluated these rules and performed an assessment of whether these rules constitute a takings under Texas Government Code, Chapter 2007. The specific intent of the rules is to establish regulations allowing for the public practice of geoscience in agency procedures in conformance with the Act. The rules would substantially advance this stated purpose by requiring that specific reports and necessary data submitted to the commission be produced, signed, sealed, and dated by licensed professional geoscientists who have obtained their licenses through the Texas Board of Professional Geoscientists.

Promulgation and enforcement of these rules would be neither a statutory nor a constitutional taking of private real property. Specifically, the rules do not affect a landowner's rights in private real property by burdening private real property, nor restricting or limiting a landowner's right to property, or reducing the value of property by 25% or more beyond that which would otherwise exist in the absence of the adopted rulemaking. These rules simply require that specific portions of applications or necessary data submitted to the commission be produced, signed, sealed, and dated by a qualified professional individual who has demonstrated his or her qualifications by obtaining a license to engage in the public practice of geoscience from the Texas Board of Professional Geoscientists. The Act also allows certain specified engineers to publicly practice geoscience in conformance with the Act. These rules do not affect any private real property.

There are no burdens imposed on private real property, and the benefits to society are better applications for environmental permits based upon reliable reports and data submitted by qualified licensed professional geoscientists.

CONSISTENCY WITH THE COASTAL MANAGEMENT PROGRAM

The commission reviewed the adopted rulemaking and found that the adoption is a rulemaking identified in Coastal Coordination Act Implementation Rules, 31 TAC §505.11(b)(2), relating to Actions and Rules Subject to the Texas Coastal Management Program (CMP), or will affect an action and/or authorization identified in Coastal Coordination Act Implementation Rules, 31 TAC §505.11(a)(6). The commission prepared a consistency determination for the rules under 31 TAC §505.22 and found that the rulemaking is consistent with the applicable CMP goals and policies. The CMP goal applicable to the rulemaking is the goal to protect, preserve, restore, and enhance the diversity, quality, quantity, functions, and values of coastal natural resource areas. CMP policies applicable to the adopted rules include the construction and operation of solid waste treatment, storage, and disposal facilities, and the discharge of municipal and industrial wastewater to coastal waters. Promulgation and enforcement of these rules will not violate (exceed) any standards identified in the applicable CMP goals and policies because the adopted rule changes do not modify or alter standards set forth in existing rules, and do not govern or authorize any actions subject to the CMP. The adopted rulemaking would require a person who prepares and submits geoscientific information to the agency to be a licensed professional geoscientist. The Act also allows certain specified engineers to publicly practice geoscience in conformance with the Act.

PUBLIC COMMENT

A public hearing was not held on this rulemaking and no comments were received during the comment period, which closed June 30, 2003.

This report must describe all borings drilled on-site to test soils and characterize groundwater and must include a site map drawn to scale showing the surveyed locations and elevations of the borings. Boring logs must include a detailed description of materials encountered including any discontinuities such as fractures, fissures, slickensides, lenses, or seams. Geophysical logs of the boreholes may be useful in evaluating the stratigraphy. Each boring must be presented in the form of a log that contains, at a minimum, the boring number; surface elevation and location coordinates; and a columnar section with text showing the elevation of all contacts between soil and rock layers, description of each layer using the unified soil classification, color, degree of compaction, and moisture content. A key explaining the symbols used on the boring logs and the classification terminology for soil type, consistency, and structure must be provided.

(i) A sufficient number of borings shall be performed to establish subsurface stratigraphy and to determine geotechnical properties of the soils and rocks beneath the facility. Other types of samples may also be taken to provide geologic and geotechnical data. The number of borings necessary can only be determined after the general characteristics of a site are analyzed and will vary depending on the heterogeneity of subsurface materials. Locations with stratigraphic complexities such as non- uniform beds that pinch out, vary significantly in thickness, coalesce, or grade into other units, will require a significantly greater degree of subsurface investigation than areas with simple geologic frameworks.

(ii) Borings shall be sufficiently deep to allow identification of the uppermost aquifer and underlying hydraulically interconnected aquifers. Borings shall penetrate the uppermost aquifer and all deeper hydraulically interconnected aquifers and be deep enough to identify the aquiclude at the lower boundary. All the borings shall be at least five feet deeper than the elevation of the deepest excavation. In addition, at least the number of borings shown on the Table of Borings shall be drilled to a depth at least 30 feet below the deepest excavation planned at the waste management unit, unless the executive director approves a different depth. If no aquifers exist within 50 feet of the elevation of the deepest excavation, at least one test hole shall be drilled to the top of the first perennial aquifer beneath the site, if sufficient data does not exist to accurately locate it. The executive director may accept data equivalent to a deep boring on the site to determine information for aquifers more than 50 feet below the site. Aquifers more than 300 feet below the lowest excavation and where the estimated travel times for constituents to the aquifer are in excess of 30 years plus the estimated life of the site need not be identified through borings.

(3) take any interim measures necessary to ensure the protection of human health and the environment. Interim measures should, to the greatest extent practicable, be consistent with the objectives of and contribute to the performance of any remedy that may be required under §330.237 of this title. The following factors shall be considered by an owner or operator in determining if interim measures are necessary:

(A) time required to develop and implement a final remedy;

(B) actual or potential exposure of nearby populations or environmental receptors to hazardous constituents;

(C) actual or potential contamination of drinking-water supplies or sensitive ecosystems;

(D) further degradation of the groundwater that may occur if remedial action is not initiated expeditiously;

(E) weather conditions that may cause hazardous constituents to migrate or be released;

(F) risks of fire or explosion, or potential for exposure to hazardous constituents as a result of an accident or failure of a container or handling system; and

(G) other situations that may pose threats to human health and the environment.

(b) An owner or operator may determine, based on information developed after implementation of the remedy has begun or other information, that compliance with requirements of §330.237(b) of this title are not being achieved through the remedy selected. In such cases, the owner or operator shall, with approval of the executive director, implement other methods or techniques that could practicably achieve compliance with the requirements unless the owner or operator makes the determination under subsection (c) of this section and if it is approved by the executive director. Failure to obtain approval from the executive director for the other methods and techniques does not relieve the owner or operator of the burden to implement an acceptable remedy.

(c) If the owner or operator determines that compliance with requirements under §330.237(b) of this title cannot be practically achieved with any currently available methods, the owner or operator shall:

(1) present to the executive director certification by a qualified groundwater scientist that compliance with requirements under §330.237(b) of this title cannot be practically achieved with any currently available methods;

(2) implement alternate measures, with the approval of the executive director, to control exposure of humans or the environment to residual contamination, as necessary to protect human health and the environment;

(3) implement alternate measures, with the approval of the executive director, for control of the sources of contamination, or for removal or decontamination of equipment, units, devices, or structures that are technically practicable and consistent with the overall objective of the remedy; and

(4) place a copy of all approved alternate measures in the operating record.

(d) All solid wastes that are managed in accordance with a remedy required under §330.237 of this title, or an interim measure required under subsection (a)(3) of this section, shall be managed in a manner that is protective of human health and the environment and that complies with applicable RCRA requirements.

(e) Remedies selected under §330.237 of this title shall be considered complete when:

(1) the owner or operator complies with the groundwater protection standards established under §330.235(h) or (i) of this title at all points within the plume of contamination that lies within or beyond the groundwater monitoring system established under §330.231(a) of this title (relating to Groundwater Monitoring Systems);

(2) compliance with the groundwater protection standards established under §330.235(h) or (i) of this title has been achieved by demonstrating that concentrations of assessment constituents have not exceeded the groundwater protection standards for a period of three consecutive years, using the statistical procedures and performance standards in §330.233(g) and (h) of this title (relating to Groundwater Sampling and Analysis Requirements). The executive director may specify an alternative length of time during which the owner or operator shall demonstrate that concentrations of assessment constituents have not exceeded the groundwater protection standards. The alternative length of time shall be based on:

(A) extent and concentration of the release;

(B) behavior characteristics of the hazardous constituents in the groundwater;

(C) accuracy of monitoring or modeling techniques, including any seasonal, meteorological, or other environmental variabilities that may affect the accuracy; and

(D) characteristics of the groundwater; and

(3) all actions required to complete the remedy have been satisfied.

(f) Within 15 days of completion of the remedy, the owner or operator shall submit to the executive director and also place in the operating record a certification by a qualified groundwater scientist that the remedy has been completed in compliance with the requirements of subsection (e) of this section.

(g) Upon submittal of satisfactory certification of the completion of the corrective action remedy, the executive director may release the owner or operator from the requirements for financial assurance for corrective action under §330.284 of this title (relating to Corrective Action for Landfills).

§330.242.Monitor-Well Construction Specifications.

(a) The following specifications must be used for the installation of groundwater monitoring wells at municipal solid waste landfills. Equivalent alternatives to these specifications may be used if prior written approval is obtained in advance from the executive director.

(1) Drilling.

(A) Monitoring wells must be drilled by a Texas-licensed driller who is qualified to drill and install monitoring wells. The installation and development shall be supervised by a licensed professional geoscientist or engineer who is familiar with the geology of the area.

(B) The well shall be drilled by a method that will allow installation of the casing, screen, etc., and that will not introduce contaminants into the borehole or casing. Drilling techniques used for boring shall take into account the materials to be drilled, depth to groundwater, total depth of the hole, adequate soil sampling, and other such factors that affect the selection of the drilling method. If any fluids are necessary in drilling or installation, then clean, treated city water shall be used; other fluids must be approved in writing by the executive director before use. If city water is used, a current chemical analysis of the city water shall be provided with the monitor-well report.

(C) The diameter of the boring shall be at least four inches larger than the diameter of the casing. When the boring is in hard rock, a smaller annulus may be approved by the executive director.

(D) During drilling of the monitoring well, a log of the boring shall be made by a licensed professional geoscientist or engineer who is familiar with the geology of the area.

(2) Casing, screen, filter pack, and seals.

(A) The well casing shall be: two to four inches in diameter; National Science Foundation-certified polyvinyl chloride (PVC) Schedule 40 or 80 pipe, flush-thread, screw joint (no glue or solvents); polytetrafluorethylene (PTFE, such as Teflon) tape or O-rings in the joints; no collar couplings. The top of the casing shall be at least two feet above ground level. Where high levels of volatile organic compounds or corrosive compounds are anticipated, stainless steel or PTFE casing and screen may be used, subject to approval by the executive director. Four-inch diameter casing is recommended because it allows larger volume samples to be obtained and provides easier access for development, pumps, and repairs. The casing shall be cleaned and packaged at the place of manufacture; the packaging shall include a PVC wrapping on each section of casing to keep it from being contaminated prior to installation. The casing shall be free of ink, labels, or other markings. The casing (and screen) shall be centered in the hole to allow installation of a good filter pack and annular seal, using appropriately placed centralizers. The top of the casing shall be protected by a threaded or slip-on top cap or by a sealing cap or screw-plug seal inserted into the top of the casing. The cap shall be vented to prevent buildup of methane or other gases and shall be designed to prevent moisture from entering the well.

(B) The screen shall be compatible with the casing and should generally be of the same material. The screen shall not involve the use of any glues or solvents for construction. A wire-wound screen is recommended to provide maximum inflow area. Field-cut slots are not permitted for well screen. Filter cloth shall not be used. A blank-pipe sediment trap, typically one to two feet, should be installed below the screen. A bottom cap is typically placed on the bottom of the sediment trap. The sediment trap shall not extend through the lower confining layer of the water-bearing zone being tested. Screen sterilization methods are the same as those for casing. Selection of the size of the screen opening should be done by a person experienced with such work and shall include consideration of the distribution of particle sizes both in the water-bearing zone and in the filter pack surrounding the screen. The screen opening shall not be larger than the smallest fraction of the filter pack.

(C) The filter pack, placed between the screen and the well bore, shall consist of pre-packaged, inert, clean silica sand or glass beads; it shall extend from one to four feet above the top of the screen. Open stockpile sources of sand or gravel are not permitted. The filter pack usually has a 30% finer grain size that is about four to ten times larger than the 30% finer grain size of the water-bearing zone; the filter pack should have a uniformity coefficient less than 2.5. The filter pack should be placed with a tremie pipe to ensure that the material completely surrounds the screen and casing without bridging. The tremie pipe shall be steam cleaned prior to the first well and before each subsequent well.

(D) The annular seal shall be placed on top of the filter pack and shall be at least two feet thick. It should be placed in the zone of saturation to maintain hydration. The seal should be composed of coarse-grain sodium bentonite, coarse-grit sodium bentonite, or bentonite grout. Special care should be taken to ensure that fine material or grout does not plug the underlying filter pack. Placement of a few inches of pre-packaged clean fine sand on top of the filter pack will help to prevent migration of the annular seal material into the filter pack. The seal should be placed on top of the filter pack with a steam-cleaned tremie pipe to ensure good distribution and should be tamped with a steam-cleaned rod to determine that the seal is thick enough. The bentonite shall be hydrated with clean water prior to any further activities on the well and left to stand until hydration is complete (eight to 12 hours, depending on the grain size of the bentonite). If a bentonite-grout (without cement) casing seal is used in the well bore, then it may replace the annular seal described in this paragraph.

(E) A casing seal shall be placed on top of the annular seal to prevent fluids and contaminants from entering the borehole from the surface. The casing seal shall consist of a commercial bentonite grout or a cement-bentonite mixture. Drilling spoil, cuttings, or other native materials are not permitted for use as a casing seal. Quick-setting cements are not permitted for use because contaminants may leach from them into the groundwater. The top of the casing seal shall be between five and two feet from the surface.

(3) Concrete pad. High-quality structural-type concrete shall be placed from the top of the casing seal (two to five feet below the surface) continuously to the top of the ground to form a pad at the surface. This formed surface pad shall be at least six inches thick and not less than four (preferably six) feet square or five (preferably six) feet in diameter. The pad shall contain sufficient reinforcing steel to ensure its structural integrity in the event that soil support is lost. The top of the pad shall slope away from the well bore to the edges to prevent ponding of water around the casing or collar.

(4) Protective collar. A steel protective pipe collar shall be placed around the casing "stickup" to protect it from damage and unwanted entry. The collar shall be set at least one foot into the surface pad during its construction and should extend at least three inches above the top of the well casing (and top cap, if present). The top of the collar shall have a lockable hinged top flap or cover. A sturdy lock shall be installed, maintained in working order, and kept locked when the well is not being bailed/purged or sampled. The well number or other designation shall be marked permanently on the protective steel collar; it is useful to mark the total depth of the well and its elevation on the collar.

(5) Protective barrier. Where monitoring wells are likely to be damaged by moving equipment or are located in heavily traveled areas, a protective barrier shall be installed. A typical barrier is three or four six- to 12-inch diameter pipes set in concrete just off the protective pad. The pipes can be joined by pipes welded between them, but consideration must be given to well access for sampling and other activities. Separation of such a pipe barrier from the pad means that the barrier can be damaged without risk to the pad and well. Other types of barriers may be approved by the executive director.

(b) Unusual conditions. Where monitoring wells are installed in unusual conditions, all aspects of the installation shall be approved in writing in advance by the executive director. Such aspects include, for example, the use of cellar-type enclosures for the top-well equipment or multiple completions in a single hole.

(c) Development. After a monitoring well is installed, it shall be developed to remove artifacts of drilling (clay films, bentonite pellets in the casing, etc.) and to open the water-bearing zone for maximum flow into the well. Development should continue until all of the water used or affected during drilling activities has been removed and field measurements of pH, specific conductance, and temperature have stabilized. Failure to develop a well properly may mean that it is not properly monitoring the water-bearing zone or may not yield adequate water for sampling even though the water-bearing zone is prolific.

(d) Location and elevation. Upon completion of a monitoring well, the location of the well and all appropriate elevations associated with the top-well equipment shall be surveyed by a registered professional surveyor. The elevation shall be surveyed to the nearest 0.01 foot above mean sea level (with year of the sea-level datum shown). The point on the well casing for which the elevation was determined shall be permanently marked on the casing. The location shall be given in terms of the latitude and longitude at least to the nearest tenth of a second or shall be accurately located with respect to the landfill grid system described in §330.55(a)(10)(F) of this title (relating to Site Development Plan).

(e) Reporting. Monitoring well installation and construction details must be submitted on forms available from the commission and must be completed and submitted within 30 days of well completion. A copy of the detailed geologic log of the boring, any particle size or other sample data from the well, and a site map drawn to scale showing the location of all monitoring wells must be submitted to the executive director at the same time. The licensed driller should be familiar with the forms required by other agencies; a copy of those forms must also be submitted to the commission.

(f) Damaged wells. Any monitoring well that is damaged to the extent that it is no longer suitable for sampling shall be reported to the executive director who may make a determination about whether to repair or replace the well.

(g) Plugging and abandonment. Any monitoring well that is no longer used shall be properly abandoned and plugged in accordance with 16 TAC §76.702 (relating to Responsibilities of the Licensee and Landowner Well Drilling, Completion, Capping, and Plugging) and §76.1004 (relating to Technical Requirements Standards for Capping and Plugging of Wells and Plugging Wells that Penetrate Undesirable Water or Constituent Zones). No abandonment shall take place without prior authorization in writing by the executive director.

This agency hereby certifies that the adoption has been reviewed by legal counsel and found to be a valid exercise of the agency's legal authority.

Chapter 335. INDUSTRIAL SOLID WASTE AND MUNICIPAL HAZARDOUS WASTE

The Texas Commission on Environmental Quality (commission) adopts amendments to §§335.1, 335.116, 335.123, 335.156, 335.172, 335.204, 335.348, and 335.553. Sections 335.1, 335.116, 335.123, 335.156, 335.172, 335.348, and 335.553 are adopted with changes to the proposed text as published in the May 30, 2003 issue of the Texas Register (28 TexReg 4266). Section 335.204 is adopted without change to the proposed text and will not be republished.

BACKGROUND AND SUMMARY OF THE FACTUAL BASIS FOR THE ADOPTED RULES

Senate Bill (SB) 405, 77th Legislature, established the Texas Board of Professional Geoscientists and the regulation of professional geoscientists. The Texas Geoscience Practice Act (the Act) requires that a person may not take responsible charge of a geoscientific report or a geoscientific portion of a report required by state agency rule unless the person is licensed through the Texas Board of Professional Geoscientists. The primary purpose of the adopted amendments is to establish regulations for the public practice of geoscience in conformance with the Act by requiring a person who prepares and submits geoscientific information to the commission to be a licensed professional geoscientist. The Act also allows certain specified engineers to publicly practice geoscience in conformance with the Act. According to the bill analysis prepared at the time of passage, the ultimate purpose of the Act was public safety through the public registration of the practice of geoscience.

SECTION BY SECTION DISCUSSION

Adopted §335.1, Definitions, amends the introductory paragraph by deleting the word "shall" and the phrase "unless the context clearly indicates otherwise." The definition of licensed professional geoscientist is adopted as new paragraph (85). The definition of person in paragraph (104) is deleted because it is defined in 30 TAC Chapter 3, Definitions. Existing paragraphs (85) - (103) are renumbered accordingly. In addition, an administrative change is made from proposal in paragraph (27) to correct "ground water" to "groundwater."

Adopted §335.116, Applicability of Groundwater Monitoring Requirements, replaces the term "qualified geologist" with "licensed professional geoscientist" regarding the demonstration of groundwater monitoring requirements. In addition, an administrative change is made from proposal in subsection (c)(1)(B) to correct "ground water" to "groundwater."

Adopted §335.123, Closure and Post-Closure (Land Treatment Facilities), replaces the term "independent qualified soil scientist" with "independent licensed professional geoscientist" regarding certification of closures.

Adopted §335.156, Applicability of Groundwater Monitoring and Response, replaces the term "qualified geologist" with "licensed professional geoscientist." At the January 8, 2003 commission agenda for the post-closure rules (Rule Log Number 2000-048-335-WS), the text of §335.156(a)(2) was inadvertently adopted as the text for §335.156(b)(2). Therefore, the correct text of §335.156(b)(2) has been properly added as originally proposed in the post-closure rules. In addition, an administrative change is made from proposal in subsection (b)(3) to correct a typographical error.

Adopted §335.172, Closure and Post-Closure Care (Land Treatment Units), replaces the term "independent qualified soil scientist" with "independent licensed professional geoscientist."

Adopted §335.204, Unsuitable Site Characteristics, replaces the term "qualified geologist" with "licensed professional geoscientist."

Adopted §335.348, General Requirements for Remedial Investigations, adds new subsection (n) requiring that all engineering and geoscientific information submitted to the agency shall be prepared by, or under the supervision of, a licensed professional engineer or licensed professional geoscientist, and shall be signed, sealed, and dated by qualified professionals as required by the Texas Engineering Practice Act and the Texas Geoscience Practice Act and the licensing and registration boards under these acts. In addition, an administrative change is made from proposal in subsection (d)(3) to correct "ground water" to "groundwater."

Adopted §335.553, Required Information, adds the requirement that all engineering and geoscientific information submitted to the agency shall be prepared by, or under the supervision of, a licensed professional engineer or licensed professional geoscientist, and shall be signed, sealed, and dated by qualified professionals as required by the Texas Engineering Practice Act and the Texas Geoscience Practice Act and the licensing and registration boards under these acts. In addition, administrative changes are made from proposal to correct "ground water" to "groundwater" and to correct cross-reference titles.

FINAL REGULATORY IMPACT ANALYSIS DETERMINATION

The commission reviewed the adopted rulemaking in light of the regulatory analysis requirements of Texas Government Code, §2001.0225, and determined that the rulemaking is not subject to §2001.0225 because it does not meet the criteria for a "major environmental rule" as defined in that statute. A "major environmental rule" means a rule the specific intent of which is to protect the environment or reduce risks to human health from environmental exposure and that may adversely affect in a material way the economy, 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 specific intent of the adopted rules is to establish regulations allowing for the public practice of geoscience in agency procedures in accordance with the Act. The Act requires that a person may not take responsible charge of a geoscientific report or a geoscientific portion of a report required by a state agency rule unless the person is licensed through the Texas Board of Professional Geoscientists. The Act also allows certain specified engineers to publicly practice geoscience in conformance with the Act. The adopted rules are not specifically intended to protect the environment or reduce risks to human health. The adopted rules are intended to establish procedures to require that specific reports and necessary data submitted to the commission be produced, signed, sealed, and dated by licensed professional geoscientists who have obtained their licenses through the Texas Board of Professional Geoscientists. Therefore, it is not anticipated that the adopted rules will adversely affect in a material way the economy, 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 commission concludes that these adopted rules do not meet the definition of major environmental rule.

Furthermore, even if the adopted rules did meet the definition of a major environmental rule, the rules are not subject to Texas Government Code, §2001.0225, because they do not accomplish any of the four results specified in §2001.0225(a). Section 2001.0225(a) applies to a rule adopted by an agency, 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.

In this case, the adopted rules do not meet any of these requirements. First, there are no federal standards that these rules would exceed. Second, the adopted rules do not exceed an express requirement of state law. Third, there is no delegation agreement that would be exceeded by these adopted rules. Fourth, the commission adopts these rules to allow for the public practice of geoscience in agency procedures in accordance with the Act. Therefore, the commission does not adopt the rules solely under the commission's general powers.

TAKINGS IMPACT ASSESSMENT

The commission evaluated these adopted rules and performed an assessment of whether these rules constitute a takings under Texas Government Code, Chapter 2007. The specific intent of the rules is to establish regulations allowing for the public practice of geoscience in agency procedures in accordance with the Act. The adopted rules would substantially advance this stated purpose by requiring that specific reports and necessary data submitted to the commission be produced, signed, sealed, and dated by licensed professional geoscientists who have obtained their licenses through the Texas Board of Professional Geoscientists.

Promulgation and enforcement of these adopted rules would be neither a statutory nor a constitutional taking of private real property. Specifically, the rules do not affect a landowner's rights in private real property by burdening private real property, nor restricting or limiting a landowner's right to property, or reducing the value of property by 25% or more beyond that which would otherwise exist in the absence of the adopted rules. These rules simply require that specific portions of applications or necessary data submitted to the commission be produced, signed, sealed, and dated by a qualified professional individual who has demonstrated his or her qualifications by obtaining a license to engage in the public practice of geoscience from the Texas Board of Professional Geoscientists. The Act also allows certain specified engineers to publicly practice geoscience in conformance with the Act. These adopted rules do not affect any private real property.

There are no burdens imposed on private real property, and the benefits to society are better applications for environmental permits based upon reliable reports and data submitted by qualified licensed professional geoscientists.

CONSISTENCY WITH THE COASTAL MANAGEMENT PROGRAM

The commission reviewed the adopted rulemaking and found that the adoption is a rulemaking identified in Coastal Coordination Act Implementation Rules, 31 TAC §505.11(b)(2), relating to Actions and Rules Subject to the Texas Coastal Management Program (CMP), or will affect an action and/or authorization identified in Coastal Coordination Act Implementation Rules, 31 TAC §505.11(a)(6). The commission prepared a consistency determination for the rules under 31 TAC §505.22 and found that the rulemaking is consistent with the applicable CMP goals and policies. The CMP goal applicable to the rulemaking is the goal to protect, preserve, restore, and enhance the diversity, quality, quantity, functions, and values of coastal natural resource areas. CMP policies applicable to the adopted rules include the construction and operation of solid waste treatment, storage, and disposal facilities, and the discharge of municipal and industrial wastewater to coastal waters. Promulgation and enforcement of these rules will not violate (exceed) any standards identified in the applicable CMP goals and policies because the adopted rule changes do not modify or alter standards set forth in existing rules, and do not govern or authorize any actions subject to the CMP. The adopted rulemaking would require a person who prepares and submits geoscientific information to the agency to be a licensed professional geoscientist. The Act also allows certain specified engineers to publicly practice geoscience in conformance with the Act.

PUBLIC COMMENT

A public hearing was not held on this rulemaking and one comment was received from the Texas Board of Professional Geoscientists (TBPG) during the comment period, which closed June 30, 2003.

RESPONSE TO COMMENT

TBPG stated that the proposed rules add needed clarification to commission rules as the rules relate to the role of professional geoscientists. TBPG recommended that §335.123(e) be modified to remove the requirement that certification be performed by the owner or operator in some cases.

The commission disagrees with this comment. 40 Code of Federal Regulations (CFR) §265.115, referenced in 30 TAC §335.123(e), requires that the owner/operator submit certification that a hazardous waste management unit or facility has been closed in accordance with the approved closure plan. Moreover, the certification must be signed by both the owner/operator and an independent licensed professional engineer or an independent licensed professional geoscientist. No change has been made in response to this comment.

TBPG commented that §335.123(e) should be modified to provide that the certification in question can be performed by either an independent licensed professional geoscientist or an independent licensed professional engineer.

40 CFR §265.115 requires certifications by an independent registered professional engineer. Section 335.123(e) allows an independent licensed professional geoscientist to certify closures in lieu of an independent licensed professional engineer. No change has been made in response to this comment.

TBPG commented that §335.172(b) should be modified to require that certification be performed by an "independent" licensed professional geoscientist.

The commission agrees with this comment and has changed the rule language to add the word "independent" before "licensed professional geoscientist."

TBPG commented that the "in lieu of" language be replaced by "or" in §335.172(b).

The commission disagrees with this comment. Existing rule language supports the TBPG recommendation to allow certifications by both independent licensed professional engineers and geoscientists. The use of the words "in lieu of" in §335.123(e) correctly highlights the fact that state regulations provide certification by independent licensed professional geoscientists as an alternative to the professional engineers required by the federal regulations. No change has been made in response to this comment.

TBPG commented that the term "registered professional engineer" should be replaced with "licensed professional engineer."

The commission agrees with this comment, and has added the word "licensed" to §335.172(b), regarding closure and post-closure of permitted status hazardous waste management units, to mirror §335.123(e) concerning closure and post-closure of interim status hazardous waste management units.

(ii) uncontaminated soil, dirt, rock, sand, and other natural or man-made inert solid materials used to fill land if the object of the fill is to make the land suitable for the construction of surface improvements. The material serving as fill may also serve as a surface improvement such as a structure foundation, a road, soil erosion control, and flood protection. Man-made materials exempted under this provision shall only be deposited at sites where the construction is in progress or imminent such that rights to the land are secured and engineering, architectural, or other necessary planning have been initiated. Waste disposal shall be considered to have occurred on any land which has been filled with man-made inert materials under this provision if the land is sold, leased, or otherwise conveyed prior to the completion of construction of the surface improvement. Under such conditions, deed recordation shall be required. The deed recordation shall include the information required under §335.5(a) of this title (relating to Deed Recordation), prior to sale or other conveyance of the property;

(ii) recycled, as explained in subparagraph (D) of this paragraph;

(iii) considered inherently waste-like, as explained in subparagraph (E) of this paragraph; or

(iv) a military munition identified as a solid waste in 40 CFR §266.202.

(C) Materials are solid wastes if they are abandoned by being:

(i) disposed of;

(ii) burned or incinerated; or

(iii) accumulated, stored, or processed (but not recycled) before or in lieu of being abandoned by being disposed of, burned, or incinerated.

(D) Except for materials described in subparagraph (H) of this paragraph, materials are solid wastes if they are "recycled" or accumulated, stored, or processed before recycling as specified in this subparagraph. The chart referred to as Table 1 indicates only which materials are considered to be solid wastes when they are recycled and is not intended to supersede the definition of solid waste provided in subparagraph (A) of this paragraph.

(i) Used in a manner constituting disposal. Materials noted with an asterisk in Column 1 of Table 1 are solid wastes when they are:

(I) applied to or placed on the land in a manner that constitutes disposal; or

(II) used to produce products that are applied to or placed on the land or are otherwise contained in products that are applied to or placed on the land (in which cases the product itself remains a solid waste). However, commercial chemical products listed in 40 CFR §261.33 are not solid wastes if they are applied to the land and that is their ordinary manner of use.

(ii) Burning for energy recovery. Materials noted with an asterisk in Column 2 of Table 1 are solid wastes when they are:

(I) burned to recover energy; or

(II) used to produce a fuel or are otherwise contained in fuels (in which cases the fuel itself remains a solid waste). However, commercial chemical products, which are listed in 40 CFR §261.33, not listed in §261.33, but that exhibit one or more of the hazardous waste characteristics, or will be considered nonhazardous waste if disposed, are not solid wastes if they are fuels themselves and burned for energy recovery.

(iii) Reclaimed. Materials noted with an asterisk in Column 3 of Table 1 are solid wastes when reclaimed (except as provided under 40 CFR §261.4(a)(17)). Materials without an asterisk in Column 3 of Table 1 are not solid wastes when reclaimed (except as provided under 40 CFR §261.4(a)(17)).

(iv) Accumulated speculatively. Materials noted with an asterisk in Column 4 of Table 1 are solid wastes when accumulated speculatively.

Figure: 30 TAC §335.1(131)(D)(iv) (No change.)

(E) Materials that are identified by the administrator of the EPA as inherently waste-like materials under 40 CFR §261.2(d) are solid wastes when they are recycled in any manner.

(F) Materials are not solid wastes when they can be shown to be recycled by being:

(i) used or reused as ingredients in an industrial process to make a product, provided the materials are not being reclaimed;

(ii) used or reused as effective substitutes for commercial products;

(iii) returned to the original process from which they were generated, without first being reclaimed or land disposed. The material must be returned as a substitute for feedstock materials. In cases where the original process to which the material is returned is a secondary process, the materials must be managed such that there is no placement on the land. In cases where the materials are generated and reclaimed within the primary mineral processing industry, the conditions of the exclusion found at 40 CFR §261.4(a)(17) apply rather than this provision; or

(iv) secondary materials that are reclaimed and returned to the original process or processes in which they were generated where they are reused in the production process provided:

(I) only tank storage is involved, and the entire process through completion of reclamation is closed by being entirely connected with pipes or other comparable enclosed means of conveyance;

(II) reclamation does not involve controlled flame combustion (such as occurs in boilers, industrial furnaces, or incinerators);

(III) the secondary materials are never accumulated in such tanks for over 12 months without being reclaimed; and

(IV) the reclaimed material is not used to produce a fuel, or used to produce products that are used in a manner constituting disposal.

(G) Except for materials described in subparagraph (H) of this paragraph, the following materials are solid wastes, even if the recycling involves use, reuse, or return to the original process, as described in subparagraph (F) of this paragraph:

(i) materials used in a manner constituting disposal, or used to produce products that are applied to the land;

(ii) materials burned for energy recovery, used to produce a fuel, or contained in fuels;

(iii) materials accumulated speculatively; or

(iv) materials deemed to be inherently waste-like by the administrator of the EPA, as described in 40 CFR §261.2(d)(1) - (2).

(H) With the exception of contaminated soils which are being relocated for use under §350.36 of this title (relating to Relocation of Soils Containing Chemicals of Concern for Reuse Purposes) and other contaminated media, materials that will otherwise be identified as nonhazardous solid wastes if disposed of are not considered solid wastes when recycled by being applied to the land or used as ingredients in products that are applied to the land, provided these materials can be shown to meet all of the following criteria:

(i) a legitimate market exists for the recycling material as well as its products;

(ii) the recycling material is managed and protected from loss as will be raw materials or ingredients or products;

(iii) the quality of the product is not degraded by substitution of raw material/product with the recycling material;

(iv) the use of the recycling material is an ordinary use and it meets or exceeds the specifications of the product it is replacing without treatment or reclamation, or if the recycling material is not replacing a product, the recycling material is a legitimate ingredient in a production process and meets or exceeds raw material specifications without treatment or reclamation;

(v) the recycling material is not burned for energy recovery, used to produce a fuel or contained in a fuel;

(vi) the recycling material can be used as a product itself or to produce products as it is generated without treatment or reclamation;

(vii) the recycling material must not present an increased risk to human health, the environment, or waters in the state when applied to the land or used in products which are applied to the land and the material, as generated:

(I) is a Class 3 waste under Subchapter R of this chapter (relating to Waste Classification), except for arsenic, cadmium, chromium, lead, mercury, nickel, selenium, and total dissolved solids; and

(II) for the metals listed in subclause (I) of this clause:

(-a-) is a Class 2 or Class 3 waste under Subchapter R of this chapter; and

(-b-) does not exceed a concentration limit under §312.43(b)(3), Table 3 of this title (relating to Metal Limits); and

(viii) notwithstanding the requirements under §335.17(a)(8) of this title (relating to Special Definitions for Recyclable Materials and Nonhazardous Recyclable Materials):

(I) at least 75% (by weight or volume) of the annual production of the recycling material must be recycled or transferred to a different site and recycled on an annual basis; and

(II) if the recycling material is placed in protective storage, such as a silo or other protective enclosure, at least 75% (by weight or volume) of the annual production of the recycling material must be recycled or transferred to a different site and recycled on a biennial basis.

(I) Respondents in actions to enforce the industrial solid waste regulations who raise a claim that a certain material is not a solid waste, or is conditionally exempt from regulation, must demonstrate that there is a known market or disposition for the material, and that they meet the terms of the exclusion or exemption. In doing so, they must provide appropriate documentation (such as contracts showing that a second person uses the material as an ingredient in a production process) to demonstrate that the material is not a waste, or is exempt from regulation. In addition, owners or operators of facilities claiming that they actually are recycling materials must show that they have the necessary equipment to do so and that the recycling activity is legitimate and beneficial.

(J) Materials that are reclaimed from solid wastes and that are used beneficially are not solid wastes and hence are not hazardous wastes under 40 CFR §261.3(c) unless the reclaimed material is burned for energy recovery or used in a manner constituting disposal.

(K) Other portions of this chapter that relate to solid wastes that are recycled include §335.6 of this title (relating to Notification Requirements), §§335.17 - 335.19 of this title, §335.24 of this title (relating to Requirements for Recyclable Materials and Nonhazardous Recyclable Materials), and Subchapter H of this chapter (relating to Standards for the Management of Specific Wastes and Specific Types of Materials).

Subchapter E. INTERIM STANDARDS FOR OWNERS AND OPERATORS OF HAZARDOUS WASTE STORAGE, PROCESSING, OR DISPOSAL FACILITIES

30 TAC §335.116, §335.123

STATUTORY AUTHORITY

The amendments are adopted under Texas Water Code, §5.103, which provides the commission with the authority to adopt rules necessary to carry out its power and duties under this code and other laws of this state; Texas Water Code, §5.105, which authorizes the commission to establish and approve all general policy of the commission by rule; and Texas Civil Statutes, Article 3271b, the Act, which authorizes the public practice of geoscience in the State of Texas.

§335.116.Applicability of Groundwater Monitoring Requirements.

(a) On November 19, 1981, the owner or operator of a surface impoundment, landfill, or land treatment facility which is used to manage hazardous waste must implement a groundwater monitoring program capable of determining the facility's impact on the quality of groundwater in the uppermost aquifer underlying the facility, except as provided in subsection (c) of this section.

(b) Except as provided in subsections (c), (d), and (g) of this section, the owner or operator must install, operate, and maintain a groundwater monitoring system which meets the requirements of 40 Code of Federal Regulations (CFR) §265.91, and must comply with 40 CFR §265.92 and §265.93, and §335.117 of this title (relating to Recordkeeping and Reporting). This groundwater monitoring program must be carried out during the active life of the facility, and for disposal facilities during the post-closure care period as well.

(c) All or part of the groundwater monitoring requirements of this subchapter may be waived if the owner or operator can demonstrate that there is a low potential for migration of hazardous waste or hazardous waste constituents from the facility via the uppermost aquifer to water supply wells (domestic, industrial, or agricultural) or to surface water. This demonstration must be in writing and must be kept at the facility. This demonstration shall be certified by a licensed professional geoscientist or geotechnical engineer and must establish the following:

(1) the potential for migration of hazardous waste constituents from the facility to the uppermost aquifer, by an evaluation of:

(A) a water balance of precipitation, evapotranspiration, runoff, and infiltration; and

(B) unsaturated zone characteristics (i.e., geologic materials, physical properties, and depth to groundwater); and

(2) the potential for hazardous waste or hazardous waste constituents which enter the uppermost aquifer to migrate to a water supply well or surface water, by an evaluation of:

(A) saturated zone characteristics (i.e., geologic materials, physical properties, and rate of groundwater flow); and

(B) the proximity of the facility to water supply wells or surface water.

(d) If an owner or operator assumes (or knows) that groundwater monitoring of indicator parameters in accordance with 40 CFR §265.91 and §265.92 would show statistically significant increases (or decreases in the case of pH) when evaluated under 40 CFR §265.93(b), he may install, operate, and maintain an alternate groundwater monitoring system (other than the one described in 40 CFR §265.91 and §265.92). If the owner or operator does decide to use an alternate groundwater monitoring system he must:

(1) prior to November 19, 1981, submit to the executive director a specific plan certified by a qualified geologist or geotechnical engineer which satisfies the requirements of 40 CFR §265.93(d)(3), for an alternate groundwater monitoring system;

(2) prior to November 19, 1981, initiate the determinations specified in 40 CFR §265.93(d)(4);

(3) prepare and submit a written report in accordance with 40 CFR §265.93(d)(5);

(4) continue to make the determinations specified in 40 CFR §265.93(d)(4) on a quarterly basis until final closure of the facility; and

(5) comply with the recordkeeping and reporting requirements in §335.117 of this title.

(e) The groundwater monitoring requirements of this subchapter may be waived with respect to any surface impoundment that:

(1) is used to neutralize wastes which are hazardous solely because they exhibit the corrosivity characteristic under 40 CFR §261.22 or are listed as hazardous wastes in 40 CFR Part 261, Subpart D, only for this reason; and

(2) contains no other hazardous wastes, if the owner or operator can demonstrate that there is no potential for migration of hazardous wastes from the impoundment. The demonstrations must establish, based upon consideration of the characteristics of the wastes and the impoundment, that the corrosive wastes will be neutralized to the extent that they no longer meet the corrosivity characteristic before they can migrate out of the impoundment. The demonstration must be in writing and must be certified by a qualified professional.

(f) For owners and operators who have not established background concentrations or values in accordance with 40 CFR §265.92(c) by November 19, 1982, the executive director may require the implementation of a groundwater assessment plan under 40 CFR §265.93, whenever he determines that existing data indicates that there is a substantial likelihood that hazardous waste or hazardous constituents from the facility have entered the uppermost aquifer.

(g) The commission may replace all or part of the requirements of this subchapter applying to a regulated unit with alternative requirements developed for groundwater monitoring set out in a permit or a post-closure order where the commission determines that:

(1) a regulated unit is situated among solid waste management units or area of concern, a release has occurred, and both the regulated unit and one or more solid waste management unit(s) or area of concern are likely to have contributed to the release; and

(2) it is not necessary to apply the requirement of this subchapter because the alternative requirements will be protective of human health and the environment. The alternative standards for the regulated unit must meet the requirements of §335.8 and §335.167 of this title (related to Closure and Remediation and Corrective Action for Solid Waste Management Units).

§335.123.Closure and Post-Closure (Land Treatment Facilities).

(a) In the closure plan under 40 Code of Federal Regulations (CFR) §265.112 and the post-closure plan under 40 CFR §265.118, the owner or operator must address the following objectives and indicate how they will be achieved:

(1) control of the migration of hazardous waste and hazardous waste constituents from the treated area into the groundwater;

(2) control of the release of contaminated run-off from the facility into surface water;

(3) control of the release of airborne particulate contaminants caused by wind erosion; and

(4) compliance with 40 CFR §265.276, concerning the growth of food-chain crops.

(b) The owner or operator must consider at least the following factors addressing the closure and post-closure care objectives of subsection (a) of this section:

(1) type and amount of hazardous waste and hazardous waste constituents applied to the land treatment facility;

(2) the mobility and the expected rate of migration of the hazardous waste and hazardous waste constituents;

(3) site location, topography, and surrounding land use, with respect to the potential effects of pollutant migration (e.g., proximity to groundwater, surface water, and drinking water sources);

(4) climate, including amount, frequency, and pH or precipitation;

(5) geological and soil profiles and surface and subsurface hydrology of the site, and soil characteristics, including cation exchange capacity, total organic carbon, and pH;

(6) unsaturated zone monitoring information obtained under 40 CFR §265.278; and

(7) type, concentration, and depth of migration of hazardous waste constituents in the soil as compared to their background concentrations.

(c) The owner or operator must consider at least the following methods in addressing the closure and post-closure care objectives of subsection (a) of this section:

(1) removal of contaminated soils;

Subchapter F. PERMITTING STANDARDS FOR OWNERS AND OPERATORS OF HAZARDOUS WASTE STORAGE, PROCESSING, OR DISPOSAL FACILITIES

30 TAC §335.156, §335.172

STATUTORY AUTHORITY

The amendments are adopted under Texas Water Code, §5.103, which provides the commission with the authority to adopt rules necessary to carry out its power and duties under this code and other laws of this state; Texas Water Code, §5.105, which authorizes the commission to establish and approve all general policy of the commission by rule; and Texas Civil Statutes, Article 3271b, the Act, which authorizes the public practice of geoscience in the State of Texas.

§335.156.Applicability of Groundwater Monitoring and Response.

(a) Except as provided in subsection (b) of this section, the rules pertaining to groundwater monitoring and response apply to owners and operators of facilities that process, store, or dispose of hazardous waste.

(1) The owner or operator must satisfy those requirements of paragraph (2) or (3) of this subsection for all wastes (or constituents thereof) contained in any such waste management unit at the facility, regardless of the time at which waste was placed in the units.

(2) Except as provided in paragraph (3) of this subsection, all solid waste management units must comply with the requirements in §335.167 of this title (relating to Corrective Action for Solid Waste Management Units). A surface impoundment, waste pile, land treatment unit, or landfill that receives hazardous waste after July 26, 1982, (hereinafter referred to as a regulated unit) must comply with the requirements of §§335.157 - 335.166 of this title (relating to Required Program; Groundwater Protection Standard; Hazardous Constituents; Concentration Limits; Point of Compliance; Compliance Period; General Groundwater Monitoring Requirements; Detection Monitoring Program; Compliance Monitoring Program; and Corrective Action Program) in lieu of §335.167 of this title for purposes of detecting, characterizing, and responding to releases to the uppermost aquifer. The financial responsibility requirements of §335.167 of this title apply to regulated units.

(3) The commission may replace all or part of the requirements of §§335.157 - 335.166 of this title with alternative requirements for groundwater monitoring and corrective action for releases to groundwater set out in the permit or in a post-closure order where the commission determines that:

(A) a regulated unit is situated among solid waste management units or area of concern, a release has occurred, and both the regulated unit and one or more solid waste management unit(s) or area of concern are likely to have contributed to the release; and

(B) it is not necessary to apply the groundwater monitoring and corrective action requirements of §§335.157 - 335.166 of this title because the alternative requirements will be protective of human health and the environment.

(4) If a permitted facility obtains an order setting out alternative requirements provided in §335.151(e) of this title (relating to Purpose, Scope, and Applicability), then the alternative requirements shall also be referenced in the facility's permit.

(b) The owner or operator's regulated unit or units are not subject to regulation for releases into the uppermost aquifer under this section and §§335.157 - 335.166 of this title if:

(1) he is exempted under 40 Code of Federal Regulations (CFR) §264.1;

(2) he operates a unit which the commission finds:

(A) is an engineered structure;

(B) does not receive or contain liquid waste or waste containing free liquids;

(C) is designed and operated to exclude liquid, precipitation, and other run-on and run-off;

(D) has both inner and outer layer of containment enclosing the waste;

(E) has a leak detection system built into each containment layer for which continuing operation and maintenance will be provided during the active life of the unit and the closure and post-closure care periods; and

(F) to a reasonable degree of certainty, will not allow hazardous constituents to migrate beyond the outer containment layer prior to the end of the post-closure care period.

(3) the commission finds, in accordance with 40 CFR §264.280(d), that the treatment zone of a land treatment unit that qualifies as a regulated unit does not contain levels of hazardous constituents that are above backgrounds levels of those constituents by an amount that is statistically significant, and if an unsaturated zone monitoring program meeting the requirements of 40 CFR §264.278 has not shown a statistically significant increase in hazardous constituents below the treatment zone during the operating life of the unit. An exemption under this paragraph can only relieve an owner or operator of responsibility to meet the requirements of this subchapter relating to groundwater monitoring and response during the post-closure care period;

(4) the commission finds that there is no potential for migration of liquid from a regulated unit to the uppermost aquifer during the active life of the regulated unit (including the closure period) and the post-closure care period specified under 40 CFR §264.117. This demonstration shall be certified by a licensed professional geoscientist or geotechnical engineer. In order to provide an adequate margin of safety in the prediction of potential migration of liquid, the owner or operator shall base any predictions on assumptions that maximize the rate of liquid migration; or

(5) he designs and operates a pile in compliance with 40 CFR §264.250(c).

(c) Sections 335.157 - 335.166 of this title apply during the active life of the regulated unit (including the closure period). After closure of the regulated unit, these sections:

(1) do not apply if all waste, waste residues, contaminated containment system components, and contaminated subsoils are removed or decontaminated at closure;

(2) apply during the post-closure care period under 40 CFR §264.117 if the owner or operator is conducting a detection monitoring program under §335.164 of this title; or

(3) apply during the compliance period under §335.162 of this title if the owner or operator is conducting a compliance monitoring program under §335.165 of this title or a corrective action program under §335.166 of this title.

§335.172.Closure and Post-Closure Care (Land Treatment Units).

(a) During the closure period, the owner or operator must:

(1) continue all operations (including pH control) necessary to maximize degradation, transformation, or immobilization of hazardous constituents within the treatment zone as required under §335.171(1) of this title (relating to Design and Operating Requirements (Land Treatment Units)), except to the extent such measures are inconsistent with paragraph (8) of this subsection;

(2) continue all operations in the treatment zone to minimize run-off of hazardous constituents as required under §335.171(3) of this title;

(3) maintain the run-on control system required under §335.171(3) of this title;

(4) maintain the run-off management system required under §335.171(4) of this title;

(5) control wind dispersal of hazardous waste if required under §335.171(6) of this title;

(6) continue to comply with any prohibitions or conditions concerning growth of food-chain crops under 40 Code of Federal Regulations (CFR) §264.276;

(7) continue unsaturated zone monitoring in compliance with 40 CFR §264.278, except that soil- pore liquid monitoring may be terminated 90 days after the last application of waste to the treatment zone; and

(8) establish a vegetative cover on the portion of the facility being closed at such time that the cover will not substantially impede degradation, transformation, or immobilization of hazardous constituents in the treatment zone. The vegetative cover must be capable of maintaining growth without extensive maintenance.

(b) For the purpose of complying with 40 CFR §264.115, when closure is completed, the owner or operator may submit to the executive director certification by an independent licensed professional geoscientist, in lieu of an independent licensed professional engineer, that the facility has been closed in accordance with the specifications in the approved closure plan.

(c) During the post-closure care period, the owner or operator must:

(1) continue all operations (including pH control) necessary to enhance degradation and transformation and sustain immobilization of hazardous constituents in the treatment zone to the extent that such measures are consistent with other post-closure care activities;

(2) maintain a vegetative cover over closed portions of the facility;

(3) maintain the run-on control system required under §335.171(3) of this title;

(4) maintain the run-off management system required under §335.171(4) of this title;

(5) control wind dispersal of hazardous waste if required under §335.171(6) of this title;

(6) continue to comply with any prohibition or conditions concerning growth of food-chain crops under 40 CFR §264.276; and

(7) continue unsaturated zone monitoring in compliance with 40 CFR §264.278, except that soil- pore liquid monitoring may be terminated 90 days after the last application of waste to the treatment zone.

(d) The owner or operator is not subject to regulation under subsections (a)(8) and (c) of this section if the commission finds that the level of hazardous constituents in the treatment zone does not exceed the background value of those constituents by an amount that is statistically significant when using the test specified in paragraph (3) of this subsection. The owner or operator may submit such a demonstration to the executive director at any time during the closure or post-closure care periods.

(1) The owner or operator must establish background soil values and determine whether there is a statistically significant increase over those values for all hazardous constituents specified in the facility permit under 40 CFR §264.271(b).

(A) Background soil values may be based on a one-time sampling of a background plot having characteristics similar to those of the treatment zone.

(B) The owner or operator must express background values and values for hazardous constituents in the treatment zone in a form necessary for the determination of statistically significant increases under paragraph (3) of this subsection.

(2) In taking samples used in the determination of background and treatment zone values, the owner or operator must take samples at a sufficient number of sampling points and at appropriate locations and depths to yield samples that represent the chemical make-up of soil that has not been affected by solid waste or leakage from the treatment zone, and the soil within the treatment zone, respectively.

(3) In determining whether a statistically significant increase has occurred, the owner or operator must compare the value of each constituent in the treatment zone to the background value for that constituent using a statistical procedure that provides reasonable confidence that constituent presence in the treatment zone will be identified. The owner or operator must use a statistical procedure that:

(A) is appropriate for the distribution of the data used to establish background values; and

(B) provides a reasonable balance between the probability of falsely identifying hazardous constituent presence in the treatment zone and the probability of failing to identify real presence in the treatment zone.

(e) The owner or operator is not subject to regulation under §§335.156 - 335.166 of this title (relating to Applicability of Groundwater Monitoring and Response; Required Programs; Groundwater Protection Standard; Hazardous Constituents; Concentration Limits; Point of Compliance; Compliance Period; General Groundwater Monitoring Requirements; Detection Monitoring Program; Compliance Monitoring Program; and Corrective Action Program); if the commission finds that the owner or operator satisfied subsection (d) of this section and if unsaturated zone monitoring under 40 CFR §264.278 indicates that hazardous constituents have not migrated beyond the treatment zone during the active life of the land treatment unit.

This agency hereby certifies that the adoption has been reviewed by legal counsel and found to be a valid exercise of the agency's legal authority.

Subchapter S. RISK REDUCTION STANDARDS

30 TAC §335.553

STATUTORY AUTHORITY

The amendment is adopted under Texas Water Code, §5.103, which provides the commission with the authority to adopt rules necessary to carry out its power and duties under this code and other laws of this state; Texas Water Code, §5.105, which authorizes the commission to establish and approve all general policy of the commission by rule; and Texas Civil Statutes, Article 3271b, the Act, which authorizes the public practice of geoscience in the State of Texas.

§335.553.Required Information.

(a) For Risk Reduction Standard Number 1 or 2, the person shall provide a final report that documents attainment of the risk reduction standard in accordance with §335.554 or §335.555 of this title (relating to Attainment of Risk Reduction Standard Number 1 and Attainment of Risk Reduction Standard Number 2). The report shall include, but is not limited to, descriptions of procedures and conclusions of the investigation to characterize the nature, extent, direction, rate of movement, volume, composition and concentration of contaminants in environmental media; basis for selecting environmental media of concern; documentation supporting selection of exposure factors; descriptions of removal or decontamination procedures performed in closure or remediation; summaries of sampling methodology and analytical results which demonstrate that contaminants have been removed or decontaminated to applicable levels; and a document that the person proposes to use to fulfill the requirements of §335.560(b) of this title (relating to Post-Closure Care and Deed Certification for Risk Reduction Standard Number 2), as applicable.

(b) Risk Reduction Standard Number 3, the person shall conduct the activities set forth in paragraphs (1) - (4) of this subsection. The results of activities required by paragraphs (1) - (3) of this subsection may be combined to address a portion of a facility or one or more facilities of a similar nature or close proximity. The submittal shall be subject to review and approval by the executive director prior to carrying out the closure or remediation. Upon completion of the approved activity, the person shall submit the final report required by paragraph (4) of this subsection.

(1) The person shall prepare a remedial investigation report which contains sufficient documentation such as, but not limited to, descriptions of procedures and conclusions of the investigation to characterize the nature, extent, direction, rate of movement, volume, composition, and concentration of contaminants in environmental media of concern, including summaries of sampling methodology and analytical results. Information obtained from attempts to attain Risk Reduction Standard Number 1 or 2 may be submitted for this purpose.

(2) The person shall prepare a baseline risk assessment report which describes the potential adverse effects under both current and future conditions caused by the release of contaminants in the absence of any actions to control or mitigate the release. The report shall also discuss the degree of uncertainty associated with the baseline risk assessment. Residential land use with on-site exposure shall be assumed to evaluate the future use condition unless the person demonstrates to the satisfaction of the executive director that a different land use assumption such as industrial use is more appropriate. The standard exposure factors set forth in Table 1 (located following paragraph (4) of this subsection) shall be used unless the person documents to the executive director's satisfaction that site-specific exposure data should be used instead.

(3) The person shall evaluate the relative abilities and effectiveness of potential remedies to achieve the requirements for remedies described in §335.561 of this title (relating to Attainment of Risk Reduction Standard Number 3: Closure/Remediation with Controls) when considering the evaluation factors described in §335.562 of this title (relating to Remedy Evaluation Factors for Risk Reduction Standard Number 3). Using this information, the person shall prepare a corrective measure study which recommends the remedy which best achieves the requirements for remedies described in §335.561 of this title. Persons may seek to satisfy the requirements of §335.564 of this title (relating to Post-Closure Care Not Required for Risk Reduction Standard Number 3) by demonstrating in the corrective measure study using the procedures of §335.563 of this title (relating to Media Cleanup Requirements for Risk Reduction Standard Number 3) that no remedy needs to be performed since the existing conditions of the facility or area conform to the media cleanup requirements without the use of removal, decontamination or control measures. Persons may also seek to satisfy the requirements of §335.564 of this title by demonstrating in the corrective measure study that following completion of their recommended removal and/or decontamination activities the conditions of the facility or area will conform to the media cleanup requirements of §335.563 of this title without the use of control measures. Upon review of the corrective measure study, the executive director may require the person to further evaluate the proposed remedy or to evaluate one or more additional remedies.

(4) The person shall submit to the executive director, for review and acceptance, a final report containing sufficient documentation which demonstrates that the remedy has been completed in accordance with the approved plan and also a document that the person proposes to use to fulfill the requirements of §335.566 of this title (relating to Deed Recordation for Risk Reduction Standard Number 3).

Figure: 30 TAC §335.553(b)(4) (No change.)

(c) For risk reduction standards Numbers 1, 2, and 3, in order for a treatment process to achieve decontamination in contrast to being a control measure, the person must demonstrate to the satisfaction of the executive director that the treatment process permanently alters all contaminants to levels that will not pose a substantial present or future threat to human health and the environment, and must further demonstrate that any residue remaining in place from the treatment will not pose the threat of any future release that would increase the concentrations of contaminants in environmental media above the cleanup levels determined for that particular risk reduction standard.

(d) For Risk Reduction Standards Numbers 1, 2, and 3, attainment of cleanup levels shall be demonstrated by collection and analysis of samples from the media of concern. Persons shall utilize techniques described in SW 846, Test Methods for Evaluating Solid Waste, EPA, or other available guidance in developing a sampling and analysis plan appropriate for the distribution, composition, and heterogeneity of contaminants and environmental media. A sufficient number of samples shall be collected and analyzed for individual compounds to both accurately assess the risk to human health and the environment posed by the facility or area and to demonstrate the attainment of cleanup levels. Noncompound-specific analytical techniques (e.g., total petroleum hydrocarbons, total organic carbon, etc.) may, where appropriate for the nature of the wastes or contaminants, be used to aid in the determination of the lateral and vertical extent and volume of contaminated media; however, such noncompound-specific analyses will serve only as indicator measures and must be appropriately supported by compound-specific analyses. Comparisons may be based on the following methods:

(1) direct comparison of the results of analysis of discrete samples of the medium of concern with the cleanup level;

(2) for a data set of ten or more samples, statistical comparison of the results of analysis utilizing the 95% confidence limit of the mean concentration of the contaminant as determined by the following expression:

Figure: 30 TAC §335.553(d)(2) (No change.)

(3) other statistical methods appropriate for the distribution of the data, subject to prior approval by the executive director.

Figure: 30 TAC §335.553(d)(3) (No change.)

(e) For Risk Reduction Standards Numbers 2 and 3, in determining toxicity information for contaminants (e.g., EPA carcinogen classification, type of toxicant, reference doses, carcinogenic slope factors, etc.), persons shall utilize values from the following sources in the order indicated. For Risk Reduction Standard Number 2, persons may utilize data from these sources that are more current than those used to derive the unadjusted medium-specific concentrations listed in §335.568 of this title (relating to Appendix II), provided that substantiating information is furnished to the executive director in the report required by §335.555(f) of this title (relating to Attainment of Risk Reduction Standard Number 2: Closure/Remediation to Health-Based Standards and Criteria).

(1) Integrated Risk Information System (IRIS);

(2) Health Effects Assessment Summary Table (HEAST);

(3) EPA Criteria Documents;

(4) Agency for Toxic Substances and Disease Registry (ATSDR) Toxicological Profiles; and

(5) other scientifically valid published sources.

(f) For Risk Reduction Standards Numbers 2 and 3, persons determining cleanup levels for contaminated media characterized by noncompound-specific analytical techniques (e.g., total petroleum hydrocarbons, total organic carbon, etc.) and for which individual compounds such as hazardous constituents are not present as contaminants, must at a minimum consider other scientifically valid published numeric criteria to address: adverse impacts on environmental quality; adverse impacts on the public welfare and safety; conditions that present objectionable characteristics (e.g., taste, odor, etc.); or conditions that make a natural resource unfit for use.

(g) All engineering and geoscientific information submitted to the agency shall be prepared by, or under the supervision of, a licensed professional engineer or licensed professional geoscientist, and shall be signed, sealed, and dated by qualified professionals as required by the Texas Engineering Practice Act and the Texas Geoscience Practice Act and the licensing and registration boards under these acts.

This agency hereby certifies that the adoption has been reviewed by legal counsel and found to be a valid exercise of the agency's legal authority.

Chapter 350. TEXAS RISK REDUCTION PROGRAM

Subchapter A. GENERAL INFORMATION

30 TAC §350.1

The Texas Commission on Environmental Quality (commission) adopts an amendment to §350.1. Section 350.1 is adopted without change to the proposed text as published in the May 30, 2003 issue of the Texas Register (28 TexReg 4274) and will not be republished.

BACKGROUND AND SUMMARY OF THE FACTUAL BASIS FOR THE ADOPTED RULE

Senate Bill (SB) 405, 77th Legislature, established the Texas Board of Professional Geoscientists and the regulation of professional geoscientists. The Texas Geoscience Practice Act (the Act) requires that a person may not take responsible charge of a geoscientific report or a geoscientific portion of a report required by state agency rule unless the person is licensed through the Texas Board of Professional Geoscientists. The primary purpose of the adopted amendment is to establish regulations for the public practice of geoscience in conformance with the Act by requiring a person who prepares and submits geoscientific information to the commission to be a licensed professional geoscientist. The Act also allows certain specified engineers to publicly practice geoscience in conformance with the Act. According to the bill analysis prepared at the time of passage, the ultimate purpose of the Act was public safety through the public registration of the practice of geoscience.

The adopted rule would require that engineering, geoscientific, and surveying information submitted to the agency shall be prepared by, or under the supervision of, a licensed professional engineer, a licensed professional geoscientist, or licensed professional surveyor and shall be signed, sealed, and dated by qualified professionals as required by the Texas Engineering Practice Act, the Texas Geoscience Practice Act, the Texas Professional Land Surveying Practices Act, and the licensing and registration boards under these acts. For professional engineers and professional land surveyors, this is not a new requirement. In the existing Chapter 350 rules, engineering plans, surveys, etc. have had to be prepared by professional engineers and land surveyors, although only the requirement to use a professional land surveyor (§350.111(a)(3)) was specifically stated in the rules. The adopted rule now specifically states that all engineering, geoscientific, and surveying information shall be prepared and submitted by qualified professionals as set forth by their respective licensing and registration regulations. Qualified professionals include professional geoscientists, professional engineers, and professional land surveyors.

SECTION DISCUSSION

Adopted §350.1, Purpose, adds the requirement that all engineering, geoscientific, and surveying information submitted to the agency shall be prepared by, or under the supervision of, a licensed professional engineer, licensed professional geoscientist, or licensed professional surveyor and shall be signed, sealed, and dated by qualified professionals as required by the Texas Engineering Practice Act, the Texas Geoscience Practice Act, the Texas Professional Land Surveying Practices Act, and the licensing and registration boards under these acts.

FINAL REGULATORY IMPACT ANALYSIS DETERMINATION

The commission reviewed the adopted rulemaking in light of the regulatory analysis requirements of Texas Government Code, §2001.0225 and determined that the rulemaking is not subject to §2001.0225 because it does not meet the criteria for a "major environmental rule" as defined in that statute.

A "major environmental rule" means a rule the specific intent of which is to protect the environment or reduce risks to human health from environmental exposure and that may adversely affect in a material way the economy, 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 specific intent of the adopted rule is to establish regulations allowing for the public practice of geoscience in agency procedures in conformance with the Act. The Act requires that a person may not take responsible charge of a geoscientific report or a geoscientific portion of a report required by a state agency rule unless the person is licensed through the Texas Board of Professional Geoscientists. The Act also allows certain specified engineers to publicly practice geoscience in conformance with the Act. The adopted rule is not specifically intended to protect the environment or reduce risks to human health. The adopted rule is intended to establish procedures to require that specific reports and necessary data submitted to the commission be produced, signed, sealed, and dated by licensed professional geoscientists who have obtained their licenses through the Texas Board of Professional Geoscientists. Therefore, it is not anticipated that the adopted rule will adversely affect in a material way the economy, 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 commission concludes that the adopted rule does not meet the definition of major environmental rule.

Furthermore, even if the adopted rulemaking did meet the definition of a major environmental rule, the amendment is not subject to Texas Government Code, §2001.0225, because it does not accomplish any of the four results specified in §2001.0225(a). Section 2001.0225(a) applies to a rule adopted by an agency, 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.

In this case, the adopted amendment to Chapter 350 does not meet any of these requirements. First, there are no federal standards that this rule would exceed. Second, the adopted rule does not exceed an express requirement of state law. Third, there is no delegation agreement that would be exceeded by the adopted rule. Fourth, the commission adopts this rule to allow for the public practice of geoscience in agency procedures in conformance with the Act. Therefore, the commission does not adopt the rule solely under the commission's general powers.

TAKINGS IMPACT ASSESSMENT

The commission evaluated the adopted rule and performed an assessment of whether the rule constitutes a takings under Texas Government Code, Chapter 2007. The specific intent of the rule is to establish regulations allowing for the public practice of geoscience in agency procedures in conformance with the Act. The adopted rule would substantially advance this stated purpose by requiring that specific reports and necessary data submitted to the commission be produced, signed, sealed, and dated by licensed professional geoscientists who have obtained their licenses through the Texas Board of Professional Geoscientists.

Promulgation and enforcement of the adopted rule would be neither a statutory nor a constitutional taking of private real property. Specifically, the rule does not affect a landowner's rights in private real property by burdening private real property, nor restricting or limiting a landowner's right to property, or reducing the value of property by 25% or more beyond that which would otherwise exist in the absence of the adopted rulemaking. The rule simply requires that specific portions of applications or necessary data submitted to the commission be produced, signed, sealed, and dated by a qualified professional individual who has demonstrated his or her qualifications by obtaining a license to engage in the public practice of geoscience from the Texas Board of Professional Geoscientists. The Act also allows certain specified engineers to publicly practice geoscience in conformance with the Act. The adopted rule does not affect any private real property.

There are no burdens imposed on private real property, and the benefits to society are better applications for environmental permits based upon reliable reports and data submitted by qualified licensed professional geoscientists.

CONSISTENCY WITH THE COASTAL MANAGEMENT PROGRAM

The commission reviewed the adopted rulemaking and found that the adoption is a rulemaking identified in Coastal Coordination Act Implementation Rules, 31 TAC §505.11(b)(2), relating to Actions and Rules Subject to the Texas Coastal Management Program (CMP), or will affect an action and/or authorization identified in Coastal Coordination Act Implementation Rules, 31 TAC §505.11(a)(6). The commission prepared a consistency determination for the rules under 31 TAC §505.22 and found that the rulemaking is consistent with the applicable CMP goals and policies. The CMP goal applicable to the rulemaking is the goal to protect, preserve, restore, and enhance the diversity, quality, quantity, functions, and values of coastal natural resource areas. CMP policies applicable to the adopted rules include the construction and operation of solid waste treatment, storage, and disposal facilities, and the discharge of municipal and industrial wastewater to coastal waters. Promulgation and enforcement of these rules will not violate (exceed) any standards identified in the applicable CMP goals and policies because the adopted rule changes do not modify or alter standards set forth in existing rules, and do not govern or authorize any actions subject to the CMP. The adopted rulemaking would require a person who prepares and submits geoscientific information to the agency to be a licensed professional geoscientist. The Act also allows certain specified engineers to publicly practice geoscience in conformance with the Act.

PUBLIC COMMENT

A public hearing was not held on this rulemaking and no comments were received during the comment period, which closed June 30, 2003.
