TITLE 30.ENVIRONMENTAL QUALITY

Part 1. TEXAS COMMISSION ON ENVIRONMENTAL QUALITY

Chapter 30. OCCUPATIONAL LICENSES AND REGISTRATIONS

Subchapter G. ON-SITE SEWAGE FACILITIES INSTALLERS, APPRENTICES, DESIGNATED REPRESENTATIVES, AND SITE EVALUATORS

30 TAC §§30.237, 30.240, 30.242, 30.244, 30.246

The Texas Commission on Environmental Quality (commission) proposes amendments to §§30.237, 30.240, 30.242, 30.244, and 30.246.

BACKGROUND AND SUMMARY OF THE FACTUAL BASIS FOR THE PROPOSED RULES

Senate Bill (SB) 405, 77th Legislature, 2001, established the Texas Board of Professional Geoscientists and the regulation of professional geoscientists. The commission has determined that individuals licensed as professional geoscientists in the soil science discipline are appropriate to perform site evaluations due to their educational and experience background in classifying soils. Therefore, the commission is proposing amendments to add individuals licensed as professional geoscientists in the soil science discipline to the list of individuals who can obtain a site evaluator license, if all of the other requirements for the site evaluator license are met.

The commission is proposing amendments to delete all of the definitions in §30.237 since the definitions are provided in 30 TAC Chapter 285, On-Site Sewage Facilities, and are duplications. Additionally, the proposed rules delete experience requirements for obtaining Installer II and site evaluator licenses. The commission has determined that otherwise qualified individuals have not been able to obtain an Installer II or site evaluator license because they have been unable to obtain the experience currently required. The proposed rules also provide consistency with language in other agency rules. Further, the current rules provide for staggered licensing dates. Since currently licensed individuals are now on a staggered renewal system and all new licensees will be on the staggered system, the proposed rules delete licensing requirements that are no longer applicable. Finally, the proposed rules make minor corrections in the language.

SECTION BY SECTION DISCUSSION

Throughout the sections, administrative changes are proposed in accordance with Texas Register requirements and to be consistent with other agency rules.

Proposed §30.237, Definitions, would delete all definitions in this section because they are duplicative of definitions in Chapter 285. To provide a reference to the definitions, language has been added that indicates that all words and terms used in the subchapter have the same meanings in the definitions given in Chapter 285.

Proposed §30.240(b)(2) and (5) would delete all requirements for experience to obtain an Installer II license. In many areas of the state, an individual seeking to obtain experience cannot get jobs to install systems allowed under the Installer I license since standard on-site sewage facilities (OSSF) are not installed due to soil and site conditions. In addition, many individuals have reported that no one will hire them to be an apprentice due to possible competition in the future. Finally, the process of verifying experience has become a resource and administrative issue. It has taken a considerable amount of time for agency staff to verify experience. To ensure that Installer IIs who do not have the experience currently required are adequately trained, the commission proposes to change the Installer II basic training course and examination. The training will be revised as necessary to meet the job task's requirements for Installer II. The examination will be changed as necessary to test the individual in the knowledge of that training. The commission has determined that the emphasis on training and testing of that training along with the training provided by the manufacturers of proprietary systems and designers of nonstandard systems will provide individuals with a greater ability to meet the job tasks required for individuals with an Installer II license than experience on only one type of system. Existing paragraphs (3) and (4) are proposed to be renumbered as new paragraphs (2) and (3). New proposed paragraph (2) adds the word "and" at the end of the phrase.

Proposed §30.240(d)(2)(C) adds a professional geoscientist license to the list of licenses, any of which would allow an individual to obtain a site evaluator license. The language is proposed to include individuals who are licensed by the Texas Board of Professional Geoscientists to practice geoscience in the soil science discipline. The commission has determined that individuals who will be licensed as professional geoscientists in the soil science discipline have the educational background and the practical experience to perform site evaluations. Therefore, the commission is proposing to add these licenses to the list of licenses in this subparagraph. The subparagraph is also proposed to be amended by deleting the certified professional soil scientist certificate from the list of licenses that an individual can have to obtain a site evaluator license. Additionally, it is no longer appropriate to include the professional soil scientist certificate as one of the prerequisites that an individual needs to obtain a site evaluator license, since any individual holding such a certificate is no longer eligible to practice soil science in Texas unless the individual holds a professional geoscientist license.

Existing §30.240(d)(2)(D) is proposed to be deleted. The requirement in the existing rule for two years of experience under another license is keeping individuals from being able to obtain the license even though the individuals have the sufficient experience. In addition, the process of verifying experience has become a resource and administrative issue. It has taken a considerable amount of time for agency staff to verify experience. To ensure that site evaluators who do not have the experience currently required are adequately trained, the commission proposes to change the site evaluator basic training course and examination. The training is currently being revised as necessary to meet the job tasks requirements for site evaluations. The examination will be changed as necessary to test the individual in the knowledge of that training. The commission has determined that the emphasis on training and testing of that training along with the training necessary to obtain another license will provide individuals with a greater ability to meet the job tasks required for individuals with a site evaluator license than will experience.

Proposed §30.242(a) adds the "site evaluator license" to the list of licenses that are required to be renewed. This will include all of the OSSF licenses. The date of "January 1, 2002," has been deleted. Proposed §30.242(a)(1) changes "Chapter" to "chapter" for consistency. Proposed §30.242(a)(2) adds, "For an individual with a current site evaluator license that expires before August 1, 2004, the individual must have completed a minimum of eight hours of approved continuing education." This language is necessary to address individuals who have been issued an initial site evaluator license for one year or more but less than two years. All of these licenses will expire before August 1, 2004. Proposed §30.242(b) corrects an incorrect citation because the currently referenced citation does not exist.

Proposed §30.244(c) changes the language from "An individual holding a current professional engineer license is not required to possess a site evaluator license" to "A professional engineer may perform site evaluations without obtaining a site evaluator license." The change is necessary for the language in this subsection to be consistent with the definition of site evaluator in §285.2(67).

Existing §30.246(a) is proposed to be deleted since the requirements expired on September 1, 2002, thus they are no longer applicable.

Existing §30.246(b) is relettered to proposed new §30.246(a). Some language from existing §30.246(c), has been combined with the language of this subsection. Individuals who either previously had a site evaluator license, or who had taken the site evaluator training class and passed the examination are required to submit the same materials. Currently, the two types of individuals are addressed in separate subsections. Therefore, combining the two subsections will avoid duplication. The word "the" has been proposed to be changed to "an" before the word "application" to agree with the context of the sentence. Language is proposed to be added after the first sentence which states, "before September 1, 2003" to set a specific date for the submission of the required materials. A new sentence is proposed to be added to provide the requirements for obtaining a site evaluator license if the individual fails to submit the required materials before September 1, 2003. A specific end date is necessary to ensure that individuals obtaining the license are current on the site evaluator training and the OSSF rules since the site evaluation is one of the most important parts of the process of ensuring that the proper system is installed.

Existing §30.246(b)(1), (2), and (c) are proposed to be deleted since the requirements are no longer applicable.

Existing §30.246(d) is relettered to proposed new §30.246(b).

Existing §30.246(e) is relettered as proposed new §30.246(c) and changes the language in the first sentence from "An individual holding a current professional engineer license is not required to possess a site evaluator license" to "A professional engineer may perform site evaluations without obtaining a site evaluator license." The change is necessary for the language in this subsection to be consistent with the definition of site evaluator in §285.2(67) and language in other subsections of the subchapter. The language in the second sentence of this subsection is proposed to be changed from "However, an individual who holds a current professional engineer license may obtain a site evaluator license by complying with the requirements in this subchapter" to "However, a professional engineer may obtain a site evaluator license by complying with the requirements in this subchapter." This change is necessary to provide consistency in the subsection.

FISCAL NOTE

Doretta Conrad, Analyst in the Budget and Planning Division, has determined that, for the first five-year period the proposed rules are in effect, there will be no significant fiscal implications for the agency or any other unit of state government as a result of administration or enforcement of the proposed rules. There will be no fiscal impact to the agency because agency staff are not issued site evaluator licenses.

Ms. Conrad also determined that, for each of the first five years the proposed rules are in effect, the public benefit anticipated from the enforcement of and compliance with the proposed rules will be potentially improved environmental performance by persons regulated by the agency. It is anticipated the public benefit from site evaluations and installations of OSSFs will be enhanced as individuals licensed under these rules would potentially receive their licenses sooner and, as such, enter into a business for performing site evaluations and installations offering the public more choices at potentially lower costs. The proposed rules might impact other state agencies or local governments with staff geoscientists who need to become licensed under these rules. The fees associated with obtaining the professional geoscientist license is $200 to cover the application and first-year license, and $150 per year after the first year. No significant fiscal implications are anticipated for any individual or business due to implementation of the proposed rules. Additionally, no significant fiscal implications are anticipated for any small or micro-business due to implementation of the proposed rules. The commission has determined that a local employment impact statement is not required because the proposed rules do not adversely affect a local economy in a material way for the first five years that the proposed rules are in effect.

DRAFT REGULATORY IMPACT ANALYSIS DETERMINATION

The commission reviewed the proposed rulemaking in light of the regulatory analysis requirements of Texas Government Code, §2001.0225 and determined that the rulemaking is not subject to §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 proposed 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. Additionally, the proposed rules would delete experience requirements for obtaining Installer II and site evaluator licenses and delete requirements that have expired and are no longer applicable. The proposed rules are not specifically intended to protect the environment or reduce risks to human health. The proposed rules are intended to allow licensed professional geoscientists who have obtained their licenses through the Texas Board of Professional Geoscientists to obtain a site evaluator license, provided they meet the other requirements for a site evaluator. Additionally, the proposed rules will delete experience requirements for obtaining Installer II and site evaluator licenses. Therefore, it is not anticipated that the proposed 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 proposed rules do not meet the definition of major environmental rule.

Furthermore, even if the proposed 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 proposed amendments to Chapter 30 do not meet any of these requirements. First, there are no federal standards that these proposed rules would exceed. Second, the proposed rules do not exceed an express requirement of state law. Third, there is no delegation agreement that would be exceeded by these proposed rules. Fourth, the commission proposes these rules to allow for the public practice of geoscience in agency procedures in conformance with the Act. Therefore, the commission does not propose the adoption of the rules solely under the commission's general powers.

The commission invites public comment on the draft regulatory impact analysis determination.

TAKINGS IMPACT ASSESSMENT

The commission evaluated these proposed rules and performed a preliminary assessment of whether these proposed rules constitute a takings under Texas Government Code, Chapter 2007. The specific intent of the proposed rules is to allow individuals licensed as professional geoscientists by the State of Texas, to become site evaluators, provided the individuals meet the other requirements for a site evaluator. Additionally, the proposed rulemaking would delete experience requirements for obtaining Installer II and site evaluator licenses and delete requirements that are no longer applicable.

Promulgation and enforcement of these proposed rules would be neither a statutory nor a constitutional taking of private real property. Specifically, the proposed 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 proposed rulemaking. These rules simply would allow individuals licensed as professional geoscientists by the State of Texas, to become site evaluators, provided the individuals meet the other requirements for a site evaluator; delete experience requirements for obtaining Installer II and site evaluator licenses; and delete requirements that are no longer applicable. These proposed 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 has reviewed the proposed rulemaking and found that the proposal 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), and will therefore require that applicable goals and policies of the CMP be considered during the rulemaking process. The commission has prepared a consistency determination for the proposed rules under 31 TAC §505.22 and found that the proposed rulemaking is consistent with the applicable CMP goals and policies. The following is a summary of that determination. The CMP goal applicable to the proposed 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 proposed rule 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 do not govern or authorize any actions subject to the CMP. The proposed rulemaking would allow individuals licensed as professional geoscientists by the State of Texas, to become site evaluators, provided the individuals meet the requirements for a site evaluator. The proposed rulemaking would also delete experience requirements for obtaining Installer II and site evaluator licenses and delete requirements that have expired and are no longer applicable. The commission invites public comment on the consistency determination of the proposed rules.

Chapter 115. CONTROL OF AIR POLLUTION FROM VOLATILE ORGANIC COMPOUNDS

The Texas Commission on Environmental Quality (commission) proposes amendments to Subchapter A, Definitions, §115.10; Subchapter C, Volatile Organic Compound Transfer Operations, §115.216 and §115.217; Subchapter D, Petroleum Refining, Natural Gas Processing, and Petrochemical Processes, §§115.352, 115.354, 115.357, and 115.359; and Subchapter H, Highly-Reactive Volatile Organic Compounds, §§115.722, 115.725 - 115.727, 115.729, 115.764, 115.767, 115.781, 115.783, 115.785, 115.787, and 115.789. These amended sections and corresponding revisions to the state implementation plan (SIP) will be submitted to the United States Environmental Protection Agency (EPA).

BACKGROUND AND SUMMARY OF THE FACTUAL BASIS FOR THE PROPOSED RULES

The commission proposes these amendments to Chapter 115, Control of Air Pollution from Volatile Organic Compounds, and revisions to the SIP in order to make a variety of changes which correct typographical errors, update cross-references, add flexibility, and amend requirements to achieve the intended volatile organic compound (VOC) emission reductions of the program.

SECTION BY SECTION DISCUSSION

Subchapter A, Definitions

The proposed amendments to §115.10, Definitions, revise the definition of "Highly-reactive volatile organic compound (HRVOC)" to specify that isobutene (2-methylpropene or isobutylene) is one of the isomers of butene. This revision is necessary to eliminate the possibility of confusion about which compounds are included as isomers of butene and because owners and operators might otherwise design their monitoring and testing plans to exclude isobutene, thereby increasing costs due to the additional speciation which would be necessary to exclude isobutene. The proposed revision is consistent with the intended scope of the definition of HRVOC, the modeling which was the basis for this definition, and the associated Chapter 115, Subchapter H, HRVOC rules which were adopted on December 13, 2002 and published in the January 3, 2003 issue of the Texas Register (28 TexReg 113).

Subchapter C, Volatile Organic Compound Transfer Operations

Division 1, Loading and Unloading of Volatile Organic Compounds

The proposed amendments to §115.216, Monitoring and Recordkeeping Requirements, revise §115.216(3)(B) to specify that vapor pressure records are not required if the total volume of VOC loaded into transport vessels is less than 20,000 gallons per day (averaged over each consecutive 30-day period). This revision is proposed because vapor pressure records are not necessary to establish compliance with the 20,000 gallon per day exemption threshold at loading operations for which the total volume of VOC loaded into transport vessels is less than 20,000 gallons per day. In addition, the proposed amendments spell out and acronym "pounds per square inch, absolute (psia)" in §115.216(3)(C).

The proposed amendments to §115.217, Exemptions, revise §115.217(a)(1) and (b)(1) by adding "to or from transport vessels" to indicate that VOC transfer includes both loading and unloading operations to or from transport vessels. The proposed amendments to §115.217 also revise §115.217(a)(2)(A) and (b)(3)(A) by replacing "any plant" with "loading operations at any plant" because these exemptions are more appropriately associated with loading operations at the plant, rather than the plant itself. In addition, the proposed amendments to §115.217 revise §115.217(a)(2)(A) and (B), (3), (4), and (5)(A); and (b)(1), (2), (3)(A) and (B), and (4) - (6), by deleting unnecessary division title references.

Subchapter D, Petroleum Refining, Natural Gas Processing, and Petrochemical Processes

Division 3, Fugitive Emission Control in Petroleum Refining, Natural Gas/Gasoline Processing, and Petrochemical Processes in Ozone Nonattainment Areas

The proposed amendments to §115.352, Control Requirements, revise §115.352(2) by replacing the word "monitored" with "inspected." This revision is necessary to ensure that §115.352(2) is not incorrectly interpreted to require the use of monitoring (with a hydrocarbon gas analyzer) to determine whether a successful repair was made to a component in heavy liquid service. Section 115.357(1) allows owners and operators to implement audio/visual/olfactory inspections on components in heavy liquid service in lieu of monitoring (with a hydrocarbon gas analyzer). Logically, the same methodology should be used after a component repair attempt as during the routinely scheduled monitoring or inspection on that component.

The proposed amendments to §115.352(2)(A)(ii) correct cross-references to subclause (IV).

The proposed amendments to §115.352 also revise §115.352(2)(D) by adding the phrase "without use of extraordinary efforts." This revision is necessary to ensure that §115.352(2)(D) is not incorrectly interpreted to require the use of extraordinary efforts, such as sealant injection, before placing a valve on the shutdown list under Subchapter D, Division 3.

In addition, the proposed amendments to §115.352 revise §115.352(2)(E) by adding language to correct an existing requirement which inadvertently requires monitoring (with a hydrocarbon gas analyzer) of components in heavy liquid service for which a repair attempt was made during a shutdown. This revision is necessary because §115.357(1) allows owners and operators to implement audio/visual/olfactory inspections on components in heavy liquid service in lieu of monitoring (with a hydrocarbon gas analyzer).

Finally, the proposed amendments to §115.352 revise §115.352(2)(E) to specify that components for which a repair attempt was made during a shutdown must be monitored (with a hydrocarbon gas analyzer) and inspected for leaks within 30 days after startup is completed following the shutdown. Currently, such monitoring and inspection is required within 30 days or at the next monitoring period, whichever occurs first, after startup is completed following the shutdown. The proposed revision will address the scenario in which a unit has a start-up with only a few days left in the monitoring period, but will continue to ensure that components for which a repair attempt was made during a shutdown are monitored shortly after startup.

The proposed amendments to §115.354, Inspection Requirements, revise §115.354(10)(A) by replacing "the time of monitoring (beginning and end)" with "the time of monitoring (i.e., the time that the organic vapor analyzer trigger is pulled to record the concentration of each component)." This revision is necessary because recording of a single time for each component, rather than the start and stop times, is available with current software. The intent of the proposed language is to require a recording of the time that the organic vapor analyzer trigger is pulled to record the concentration of each component, thereby allowing auditors to determine pace anomalies.

The proposed amendments to §115.354 also revise §115.354(10)(C) by adding language which specifies that notations of database changes include changes to the monitored concentration, addition or deletion of components, or monitoring schedule. This revision is necessary because the current §115.354(10)(C) could be interpreted to require a notation of changes which are not needed to demonstrate compliance (for example, a more accurate description of a component's location).

The proposed amendment to §115.357, Exemptions, revises §115.357(7) by replacing the incorrect term "facilities" with "plant sites covered by a single account number." This is consistent with the intended scope of this exemption as previously identified in the January 3, 2003 issue of the Texas Register (28 TexReg 153) and documentation for the 1993 rulemaking in which this exemption was added. The acronym "HRVOC" in §114.357(10) is also spelled out as highly-reactive volatile organic compound because it is only used once in the section.

The proposed amendments to §115.359, Counties and Compliance Schedules, revise the compliance date in §115.359(2) and (3) from December 31, 2003 to March 31, 2004 in order to provide more time for the regulated community to comply and also revise a reference in §115.359(3) from "appropriate regional office" to "executive director."

Subchapter H, Highly-Reactive Volatile Organic Compounds

Division 1, Vent Gas Control

The proposed amendments to §115.722, Site-wide Cap and Control Requirements, revise §115.722(b) by replacing the phrase "comply with" with the phrase "meet the requirements of" because the current language may be interpreted as requiring direct compliance with selected provisions of 40 Code of Federal Regulations (CFR) §60.18. This amendment is intended to update the language that incorporates the requirements of that section without implying that the rule establishes an independent requirement to comply with that federal rule. The acronyms "VOC" and "DERC" are deleted because the terms volatile organic compound and discrete emission reduction credit are used only once in the section.

The proposed amendments to §115.725, Monitoring and Testing Requirements, revise §115.725(a) by replacing the term "actual and expected" with the term "maximum potential." This correction is also made in §115.725(c). Additionally, new language is added to the end of §115.725(a) to allow the use of facility process knowledge to supplement actual testing when necessary.

The proposed amendments to §115.725(c) expand the acceptable period to develop test data by referencing testing which was conducted before "approval of the test plan" and removing the existing language that specifies a deadline of "December 31, 2002." Supplemental language is added to further define the acceptability and validity of the test data by requiring that the owner or operator notify the appropriate regional office at least 45 days prior to testing to provide the appropriate regional office with an opportunity to observe the testing. In addition, a reference to submit the data to the "Engineering Services Team" has been changed to "executive director."

The term "pre-approved" is replaced with the term "approved" in §115.725(d)(8) to provide the executive director with more latitude in accepting modified monitoring methods. In addition, the commission solicits comments on what degree of flexibility may be needed in §115.725(d). Specifically, the commission solicits comments on the testing necessary for vent gas streams controlled by flares, the specific constituents other than HRVOC for which monitoring is required, direct measurement of British thermal units (Btu) in lieu of Btu calculations from component properties, and adjustments to the accuracy requirements for meters.

The rule language in §115.725(e)(2)(C) is corrected to better define that the material loaded immediately previous to the current loading operation refers to the material in the transport vessel by adding the phrase "into the vessel."

The proposed amendments to §115.726, Recordkeeping and Reporting Requirements, revise §115.726(a) by specifying where test plans and quality assurance plans must be submitted. In addition, new §115.726(a)(1)(C) and (2)(C) define the turnaround time for quality assurance plans and test plans submitted to the commission. This language is aimed at encouraging the timely submittal of quality assurance plans and test plans. Specifically, the new §115.726(a)(1)(C) is being proposed at industry's request so that the affected owners and operators will have the assurance that they can send in their quality assurance plans early (allowing time for the agency to review the plans) and have sufficient time to purchase and begin monitoring by December 31, 2004 after the agency's review. However, if an owner or operator elects to wait to submit a plan until April 30, 2004 and is issued a deficiency letter on day 180, there will be no relief for failure to implement the required monitoring by December 31, 2004. In addition, the owner or operator must submit a corrected quality assurance plan within 60 days of the date of any deficiency and/or additional requirements letter. If an approval or detailed deficiency and/or directed additional requirements letter is not issued within 180 days of receipt by the executive director, then the quality assurance plan is approved by default.

Similarly, the new §115.726(a)(2)(C) is being proposed so that the affected owners and operators will have the assurance that they can send in their test plans early (allowing time for the agency to review the plans) and have sufficient time to conduct testing by December 31, 2004 after the agency's review. However, if an owner or operator elects to wait to submit a plan until April 30, 2004 and is issued a deficiency letter on day 45, there will be no relief for failure to implement the required testing by December 31, 2004. In addition, the owner or operator must submit a corrected test plan within 15 days of the date of any deficiency and/or additional requirements letter. If an approved or detailed deficiency and/or additional requirements letter is not issued within 45 days of receipt by the executive director, then the test plan is approved by default, provided the testing is to be conducted in accordance with the appropriate reference methods and procedures specified in §115.125 (Testing Requirements) without deviation.

Also, §115.726(c) is amended to specify that an owner or operator does not necessarily need to be subject to both §115.722 and §115.725(d) or (e) in order to comply with the recordkeeping requirements of this section. Therefore, the word "and" is being replaced by "or."

The recordkeeping requirements in §115.726(c)(5) are already addressed in §115.726(f), so this duplicative language is proposed for deletion. In addition, §115.726(f) is being revised with a phrase added to specify that the owner or operator is to maintain not only records required in this section, but also other records as necessary to demonstrate continuous compliance.

Finally, the proposed amendments to §115.726 add a new §115.726(d)(3), which requires the owners or operators of vent gas streams and flares that have no potential to emit HRVOC to maintain records demonstrating that they have no potential to emit HRVOC.

The proposed amendments to §115.727, Exemptions, revise §115.727(a) by acronyming the term parts per million by volume as "ppmv" and deleting inadvertent references to §115.726(d) and (f). The recordkeeping specified in §115.726(d) and (f) is necessary in order to demonstrate compliance with §115.727(a).

The proposed amendments to §115.727 also revise §115.727(b) by adding a section title which is necessary due to the proposed revisions to §115.727(a) described in the previous paragraph.

In addition, the proposed amendments to §115.727 add new §115.727(e)(1) and (f) for vent gas streams and flares, respectively, that have no potential to emit HRVOC. The proposed amendments to §115.727 also add new §115.727(e)(2) for a vent gas stream that has an HRVOC concentration less than 100 parts per million by volume at all times, provided that the total maximum potential HRVOC emissions for all vent gas streams exempted under §115.727(e)(2) is less than 5.0% of the HRVOC cap for the account specified in §115.722(a). In addition, the proposed amendments to §115.727 add new §115.727(3), which exempts pressure tanks, laboratory vent hoods, instrumentation air systems, and a variety of combustion sources. The proposed new exemptions are appropriate in order to exclude sources for which monitoring and testing for HRVOC would be impractical due to the owner's or operator's certainty that HRVOCs would be present in low concentrations or would not be present at any time. Vent gas streams and the streams to flares must have no detectable amount of any HRVOCs by any currently available methods of detection for the HRVOCs to be considered exempt under §115.727(e)(1) or (f). Extremely low concentrations of HRVOCs can be detected, so the commission is specifically seeking detailed comments on setting an appropriate level for allowing exemption from testing or monitoring.

The proposed amendments to §115.729, Counties and Compliance Schedules, revise the compliance date in §115.729(1)(A) from June 30, 2004 to December 31, 2004 in order to provide more time for the regulated community to comply with the testing requirements of §115.725. In addition, the proposed amendments to §115.729(1)(A) revise "executive director" to "appropriate regional office and any local air pollution control agency with jurisdiction" to specify where within the agency the testing results are to be submitted.

Subchapter H, Highly-Reactive Volatile Organic Compounds

Division 2, Cooling Tower Heat Exchange Systems

The proposed amendments to §115.764, Monitoring Requirements, revise §115.764(a)(5) and (b)(5) to specify where to sample for total strippable VOC by adding the phrase, "in the cooling tower water." In addition, the commission solicits comments on what degree of flexibility may be needed in §115.764(a) - (c). Specifically, the commission solicits comments on the specific constituents that must be determined from samples, the appropriate time allowed to determine sample content, the frequency of alternate sampling when continuous monitors are out of operation, and the executive director's approval of modifications to the monitoring requirements on a case-by-case basis.

In addition, a new §115.764(d)(3) defines the turnaround time for quality assurance plans submitted to the commission. This language is aimed at encouraging the timely submittal of quality assurance plans. Specifically, the new §115.764(d)(3) is being proposed at industry's request so that affected owners and operators will have the assurance that they can send in their plans early (allowing time for the agency to review the plans) and have sufficient time to purchase and begin monitoring by December 31, 2004 after the agency's review. However, if an owner or operator elects to wait to submit a plan until April 30, 2004 and is issued a deficiency letter on day 180, there will be no relief for failure to implement the required monitoring by December 31, 2004. In addition, the owner or operator must submit a corrected quality assurance plan within 60 days of the date of any deficiency and/or additional requirements letter. If an approval or detailed deficiency and/or directed additional requirements letter is not issued within 180 days of receipt by the executive director, then the quality assurance plan is approved by default.

The proposed amendments to §115.764 also add new §115.764(e) which establishes an alternative to the monitoring requirements of §115.764(a)(2) - (5) and (b)(2) - (5). Specifically, in lieu of §115.764(a)(2) - (5) and (b)(2) - (5), the owner or operator of cooling tower heat exchange systems in which no individual heat exchanger has 5.0% or greater HRVOC in the process-side fluid shall determine total strippable VOC and the HRVOC concentration in the cooling tower water at least once per month, with an interval of not less than 20 days between samples, using the appropriate methods in §115.766. If the total HRVOC concentration in the cooling tower water is ten parts per billion by weight or greater, the owner or operator shall determine total strippable VOC at least daily.

Finally, the proposed amendments to §115.764 add new §115.764(f) which establishes an alternative to the continuous flow monitor requirements of §115.764(a)(1) and (b)(1). Specifically, in lieu of §115.764(a)(1) and (b)(1), the owner or operator of cooling tower heat exchange systems may use the maximum potential flow rate based on manufacturer's pump performance data, assuming no back pressure.

The proposed amendments to §115.767, Recordkeeping Requirements, add a new §115.767(d) and (e), which establish recordkeeping requirements necessary to document compliance with new §115.764(e) and (f), respectively, described in the preceding two paragraphs.

Subchapter H, Highly-Reactive Volatile Organic Compounds

Division 3, Fugitive Emissions

The proposed amendments to §115.781, General Monitoring and Inspection Requirements, revise §115.781(a) to specify that individual identification of components is not required. The acceptable methods for identifying the components of each process unit in HRVOC service are given in the existing §115.781(a)(1) - (6). The proposed revision to §115.781(a) is necessary due to the inherent difficulties associated with individually tagging all components.

The proposed amendments to §115.781 also revise §115.781(b)(4) to specify that components for which a repair attempt was made during a shutdown must be monitored (with a hydrocarbon gas analyzer) and inspected for leaks within 30 days after startup is completed following the shutdown. Currently, such monitoring and inspection is required within 30 days or at the next monitoring period, whichever occurs first, after startup is completed following the shutdown. The proposed revision will address the scenario in which a unit has a start-up with only a few days left in the monitoring period, but will continue to ensure that components for which a repair attempt was made during a shutdown are monitored shortly after startup.

In addition, the proposed amendments to §115.781 revise §115.781(b)(7) to specify that if an unsafe-to-monitor valve is not considered safe to monitor within a calendar year, it must be monitored as soon as possible during safe-to-monitor times. This revision is necessary to ensure that monitoring personnel are not unnecessarily exposed to unsafe conditions.

Finally, the proposed amendments to §115.781 revise the leak-skip option available under §115.781(f) by adding blind flanges, caps, or plugs at the end of a pipe or line containing HRVOC to the list of components eligible for the leak-skip option because these components are functionally similar to the components (i.e., connectors, bolted manways, heat exchanger heads, hatches, and sump covers), which are currently allowed to use this leak-skip option.

The proposed amendment to §115.783, Equipment Standards, revises §115.783 by adding a new §115.783(6), which specifies that except for pressure relief valves, no valves shall be installed or operated at the end of a pipe or line containing HRVOC unless the pipe or line is sealed with a second valve, a blind flange, or a tightly-fitting plug or cap. The sealing device may be removed only while a sample is being taken or during maintenance operations, and when closing the line, the upstream valve shall be closed first. This new paragraph is consistent with the existing §115.352(4) and is necessary to prevent excess fugitive emissions resulting from the opening of an open-ended valve. In addition, the proposed amendments spell out and acronym "highly-reactive volatile organic compound (HRVOC)" in §115.783(3).

The proposed amendments to §115.785, Testing Requirements, revise §115.785(3) by replacing a reference to the Engineering Services Team and the regional office with a reference to the executive director. The proposed amendments to §115.785 also revise §115.785(5) for consistency with the revisions to §115.725(c) described earlier in this preamble.

The proposed amendments to §115.787, Exemptions, revise §115.787(c)(6) to include a reference to the definition of sampling connection system in 40 CFR §63.161, and add the Federal Register publication date of federal regulations.

The proposed amendments to §115.789, Counties and Compliance Schedules, revise §115.789(1) to specify that the schedule in the leak-skip option of §115.781(f) applies to connectors, blind flanges, caps, or plugs at the end of a pipe or line containing HRVOC, bolted manways, heat exchanger heads, hatches, and sump covers for which the owner or operator has notified the appropriate regional office and local air pollution control program that §115.781(f) will be used to establish the monitoring schedule for these components. This revision is necessary because the monitoring schedule under the leak-skip option of §115.781(f) extends beyond the compliance schedule in §115.789(1).

In addition, the proposed amendments to §115.789 revise the compliance dates in §115.789(1), (2), (5), and (6) from December 31, 2003 to March 31, 2004 in order to provide more time for the regulated community to comply. Finally, the proposed amendments to §115.789 revise the compliance date in §115.789(4) from December 31, 2003 to December 31, 2004 in order to provide more time for the regulated community to conduct testing and for consistency with the revisions to §115.729(1) described earlier in this preamble.

FISCAL NOTE: COSTS TO STATE AND LOCAL GOVERNMENT

John Davis, Analyst with Strategic Planning and Appropriations, determined that for each year of the first five-year period the proposed rules are in effect, there will be no fiscal implications to the agency or any other unit of state or local government due to administration or enforcement of the proposed rules. The commission anticipates no fiscal implications for any other unit of state or local government to comply with the proposed rules because none of the sources required to comply with the proposed Chapter 115 requirements are owned or operated by units of state or local government.

PUBLIC BENEFITS AND COSTS

Mr. Davis also determined that for each year of the first five years the proposed rules are in effect, the public benefit anticipated from enforcement of and compliance with the proposed rules would be increased compliance with air emission standards due to rules that are more understandable.

The commission estimates that approximately 140 privately-owned and operated facilities in Brazoria, Chambers, Collin, El Paso, Dallas, Denton, Fort Bend, Galveston, Hardin, Harris, Jefferson, Liberty, Montgomery, Orange, Tarrant, and Waller Counties would be subject to the proposed rules.

The proposed amendments are intended to make a variety of changes which correct typographical errors, update cross-references, add flexibility, and amend requirements to achieve the intended emission reductions of the program. No fiscal implications resulting from the implementation of the proposed rules are expected.

SMALL BUSINESS AND MICRO-BUSINESS ASSESSMENT

The commission has been unable to identify any small or micro-businesses which would be affected by the proposed rules. The majority of sites affected by the proposed rules are large petrochemical and industrial businesses. If there are affected small or micro-businesses, however, no adverse fiscal implications are anticipated for small or micro-businesses as a result of implementation of the proposed rules.

LOCAL EMPLOYMENT IMPACT STATEMENT

The commission has reviewed this proposed rulemaking and determined that a local employment impact statement is not required because the proposed rules would not adversely affect a local economy in a material way for the first five years that the proposed rules are in effect.

DRAFT REGULATORY IMPACT ANALYSIS DETERMINATION

The commission reviewed the proposed rulemaking in light of the regulatory analysis requirements of Texas Government Code, §2001.0225, and determined that this proposal is not subject to §2001.0025 because it does not meet the definition of a "major environmental rule" as defined in that statute. "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, productivity, competition, jobs, the environment, or the public health and safety of the state or a sector of the state.

This proposal is not a major environmental rule because its primary purpose is to make a variety of changes which correct typographical errors, update cross-references, add flexibility, and amend requirements to achieve the intended emission reductions of the program.

In addition, a draft regulatory impact analysis is not required because the rules do not meet any of the four applicability criteria for requiring a regulatory analysis of a "major environmental rule" as defined in the Texas Government Code. Section 2001.0225 applies only to a major environmental rule the result of which is to: 1) exceed a standard set by federal law, unless the rule is specifically required by state law; 2) exceed an express requirement of state law, unless the rule is specifically required by federal law; 3) exceed a requirement of a delegation agreement or contract between the state and an agency or representative of the federal government to implement a state and federal program; or 4) adopt a rule solely under the general powers of the agency instead of under a specific state law. This proposal does not exceed a standard set by federal law, and the proposed technical requirements are consistent with applicable federal standards. In addition, this proposal does not exceed an express requirement of state law and is not proposed solely under the general powers of the agency, but is specifically authorized by the provisions cited in the STATUTORY AUTHORITY section of this preamble. Finally, this proposal does not exceed a requirement of a delegation agreement or contract to implement a state and federal program. The commission invites public comment on the draft regulatory impact analysis determination.

TAKINGS IMPACT ASSESSMENT

The commission evaluated this rulemaking action and performed an analysis of whether the proposed rules are subject to Texas Government Code, Chapter 2007. The primary purpose of the rulemaking is to make a variety of changes which correct typographical errors, update cross-references, add flexibility, and amend requirements to achieve the intended emission reductions of the program. Promulgation and enforcement of these proposed rules would be neither a statutory nor a constitutional taking because they do not affect private real property. Specifically, the proposed rules do not affect a landowner's rights in private real property because this proposal does not burden (constitutionally), nor restrict or limit the owner's right to property and reduce its value by 25% or more beyond that which would otherwise exist in the absence of the rules. Therefore, these rules will not constitute a takings under the Texas Government Code, Chapter 2007.

CONSISTENCY WITH THE COASTAL MANAGEMENT PROGRAM

The commission reviewed the proposed rulemaking and found that the proposal is a rulemaking identified in Coastal Coordination Act Implementation Rules, 31 TAC §505.11, or will affect an action/authorization identified in Coastal Coordination Act Implementation Rules, 31 TAC §505.11, and therefore, will require that applicable goals and policies of the Texas Coastal Management Program (CMP) be considered during the rulemaking process.

The commission determined that the proposed rulemaking action is consistent with the applicable CMP goals and policies. The CMP goal applicable to this rulemaking action is the goal to protect, preserve, and enhance the diversity, quality, quantity, functions, and values of coastal natural resource areas (31 TAC §501.12(1)). No new sources of air contaminants will be authorized. The CMP policy applicable to this rulemaking action is the policy that commission rules comply with regulations in 40 CFR, to protect and enhance air quality in the coastal area (31 TAC §501.14(q)). This rulemaking action complies with 40 CFR. Therefore, in compliance with 31 TAC §505.22(e), this rulemaking action is consistent with CMP goals and policies. Interested persons may submit comments on the consistency of the proposed rules with the CMP during the public comment period.

EFFECT ON SITES SUBJECT TO THE FEDERAL OPERATING PERMIT PROGRAM

Chapter 115 is an applicable requirement under 30 TAC Chapter 122; therefore, owners or operators subject to the federal operating permit program must, consistent with the revision process in Chapter 122, revise their operating permit to include the revised Chapter 115 requirements for each emission unit at their sites affected by the revisions to Chapter 115.

ANNOUNCEMENT OF HEARING

Public hearings on this proposal will be held in Houston on June 2, 2003, at 2:00 p.m. at the City of Houston, City Hall Annex Public Level Conference Room, located at the City Hall Annex Building, 900 Bagby, Street Level, and at 7:00 p.m. at the City of Houston, City Council Chambers, located at 901 Bagby; and in Arlington on June 4, 2003, at 2:00 p.m. at North Central Texas Council of Governments, Third Floor, Transportation Board Room, located at 616 Six Flags Drive, Suite 200.

The proposed amendments implement THSC, §§382.002, 382.011, 382.012, 382.016, and 382.017.

§115.781.General Monitoring and Inspection Requirements.

(a) The owner or operator shall identify the components of each process unit in highly-reactive volatile organic compound (HRVOC) service which is subject to this division (relating to Fugitive Emissions). Such identification must allow for ready identification of the components, and distinction from any components which are not subject to this division. [ Except for connectors, each component shall be labeled with a unique component identification code. Connectors are not required to be individually labeled if they are clearly identified individually in the master components log. ] The components [ also ] must be identified by one or more of the following methods:

(1) - (6) (No change.)

(b) Each component in the process unit must be monitored according to the requirements of Subchapter D, Division 3 of this chapter (relating to Fugitive Emission Control in Petroleum Refining, Natural Gas/Gasoline Processing, and Petrochemical Processes in Ozone Nonattainment Areas), except that the following additional requirements apply.

(1) - (3) (No change.)

(4) All components for which a repair attempt was made during a shutdown shall be monitored (with a hydrocarbon gas analyzer) and inspected for leaks within 30 days [ or at the next monitoring period, whichever occurs first, ] after startup is completed following the shutdown.

(5) - (6) (No change.)

(7) An unsafe-to-monitor or difficult-to-monitor component for which quarterly monitoring is specified may instead be monitored as follows [ annually ].

(A) An unsafe-to-monitor component is a component that the owner or operator determines is unsafe to monitor because monitoring personnel would be exposed to an immediate danger as a consequence of conducting quarterly monitoring. Components which are unsafe to monitor shall be identified in a list made available upon request. If an unsafe-to-monitor valve is not considered safe to monitor within a calendar year, then it shall be monitored as soon as possible during safe-to-monitor times. For components in light liquid or heavy liquid service, inert gas or hydraulic testing shall be conducted at normal operating temperature and pressure to assure in-place leak-free performance before each startup of the process unit where the unsafe-to-monitor component is located. Inert gas or hydraulic testing is not required more than four times per year or more than once a month if the unsafe-to-monitor component has not been found to leak in the 12 consecutive months preceding startup. Leak-free performance shall be evaluated by audio and visual inspections in concert with ability to hold operating pressure for hydraulic testing and soap bubble screening for gas testing.

(B) A difficult-to-monitor component is a component that cannot be inspected without elevating the monitoring personnel more than two meters above a permanent support surface. A difficult-to-monitor component for which quarterly monitoring is specified may instead be monitored annually.

(8) - (10) (No change.)

(c) - (e) (No change.)

(f) As an alternative to the requirements of subsection (b)(3) of this section for blind flanges, caps, or plugs at the end of a pipe or line containing HRVOC, connectors, bolted manways, heat exchanger heads, hatches, and sump covers, the owner or operator may elect to monitor all of these components in a process unit by April 1, 2006 and then conduct subsequent monitoring at the following frequencies:

(1) once per year (i.e., 12-month period), if the percent leaking blind flanges, caps, or plugs at the end of a pipe or line containing HRVOC, connectors, bolted manways, heat exchanger heads, hatches, and sump covers in the process unit was 0.5% or greater during the last required annual or biennial monitoring period;

(2) once every two years, if the percent leaking blind flanges, caps, or plugs at the end of a pipe or line containing HRVOC, connectors, bolted manways, heat exchanger heads, hatches, and sump covers was less than 0.5% during the last required monitoring period. An owner or operator may comply with this paragraph by monitoring at least 40% of the components in the first year and the remainder of the components in the second year. The percent leaking connectors, bolted manways, heat exchanger heads, hatches, and sump covers will be calculated for the total of all monitoring performed during the two-year period;

(3) if the owner or operator of a process unit in a biennial leak detection and repair program calculates less than 0.5% leaking blind flanges, caps, or plugs at the end of a pipe or line containing HRVOC, connectors, bolted manways, heat exchanger heads, hatches, and sump covers from the two-year monitoring period, the owner or operator may monitor the components one time every four years. An owner or operator may comply with the requirements of this paragraph by monitoring at least 20% of the components each year until all connectors, bolted manways, heat exchanger heads, hatches, and sump covers have been monitored within four years;

(4) if a process unit complying with the requirements of paragraph (3) of this subsection using a four-year monitoring interval program has greater than or equal to 0.5% but less than 1.0% leaking blind flanges, caps, or plugs at the end of a pipe or line containing HRVOC, connectors, bolted manways, heat exchanger heads, hatches, and sump covers, the owner or operator shall increase the monitoring frequency to one time every two years. An owner or operator may comply with the requirements of this paragraph by monitoring at least 40% of the components in the first year and the remainder of the components in the second year. The owner or operator may again elect to use the provisions of paragraph (3) of this subsection when the percent leaking components decreases to less than 0.5%;

(5) if a process unit complying with requirements of paragraph (3) of this subsection using a four-year monitoring interval program has greater than or equal to 1.0% but less than 2.0% leaking blind flanges, caps, or plugs at the end of a pipe or line containing HRVOC, connectors, bolted manways, heat exchanger heads, hatches, and sump covers, the owner or operator shall increase the monitoring frequency to one time per year. The owner or operator may again elect to use the provisions of paragraph (3) of this subsection when the percent leaking components decreases to less than 0.5%; and

(6) if a process unit complying with requirements of paragraph (3) of this subsection using a four-year monitoring interval program has 2.0% or greater leaking blind flanges, caps, or plugs at the end of a pipe or line containing HRVOC, connectors, bolted manways, heat exchanger heads, hatches, and sump covers, the owner or operator shall increase the monitoring frequency to quarterly. The owner or operator may again elect to use the provisions of paragraph (3) of this subsection when the percent leaking components decreases to less than 0.5%.

§115.783.Equipment Standards.

The following equipment standards shall apply.

(1) - (2) (No change.)

(3) Each pressure relief valve in gaseous highly-reactive volatile organic compound (HRVOC) [ HRVOC ] service that vents to atmosphere which is installed in series with a rupture disk, pin, second relief valve, or other similar leak-tight pressure relief component, shall be equipped with a pressure sensing device or an equivalent device or system between the pressure relief valve and the other pressure relief component to monitor for leakage past the first component. When leakage is detected past the first component, that component shall be repaired or replaced as soon as practicable, but no later than 30 calendar days after the failure is detected.

(4) Pumps, compressors, and agitators installed on or after July 1, 2003 shall be equipped with a shaft sealing system that prevents or detects emissions of VOC from the seal.

(A) (No change.)

(B) The executive director may approve shaft sealing systems different from those specified in subparagraph (A) of this paragraph. The executive director:

(i) shall consider on a case-by-case basis the technological circumstances of the individual pump, compressor, or agitator; and

(ii) must determine that the alternative shaft sealing system will result in the lowest emissions level that the pump, compressor, or agitator is capable of meeting after the application of best available control technology before approving the alternative shaft sealing system . [ ; and ]

Chapter 312. SLUDGE USE, DISPOSAL, AND TRANSPORTATION

The Texas Commission on Environmental Quality (commission) proposes amendments to §§312.8, 312.50, and 312.64.

BACKGROUND AND SUMMARY OF THE FACTUAL BASIS FOR THE PROPOSED RULES

Senate Bill (SB) 405, 77th Legislature, established the Texas Board of Professional Geoscientists and the regulation of professional geoscientists. The 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 proposed 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

Throughout the sections, administrative changes are proposed in accordance with Texas Register requirements and to be consistent with other agency rules.

Proposed §312.8, General 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 proposed to be added as new paragraph (46) and the definition of qualified groundwater scientist is proposed to be deleted. The definitions for Clean Water Act (CWA), commission, United States Environmental Protection Agency (EPA), executive director, and person are also proposed to be deleted because these definitions are located in 30 TAC §3.2. All existing paragraphs are proposed to be renumbered accordingly.

Proposed §312.50(a), Storage and Staging of Sludge at Beneficial Use Sites, substitutes "must" for "shall." In proposed subsection (a)(4), the use of "groundwater" as a single word is proposed to reflect current agency usage and a minor punctuation error is corrected. Proposed subsection (a)(4) would require that certification of the completed storage area lining be made by a licensed professional engineer or licensed professional geoscientist prior to using the facilities and that the certification be signed, sealed, and dated by a licensed professional engineer or licensed professional geoscientist.

Proposed §312.64, Management Practices, amends subsection (n) by substituting "must" for "shall" in the first sentence and replacing licensed professional geoscientist or licensed professional engineer for qualified groundwater scientist as the person who shall develop the groundwater monitoring program or certify that sewage sludge will not contaminate an aquifer. The licensed professional geoscientist shall also sign, seal, and date the certification or the results of the program.

FISCAL NOTE

Doretta Conrad, Analyst in the Budget and Planning Division, has determined that, for the first five-year period the proposed rules are in effect, there will be no significant fiscal implications for the agency or any other unit of state government as a result of administration or enforcement of the proposed rules. There will be no fiscal impact to the agency; however, there may be fiscal implications to the agency if the agency elects to reimburse staff for the annual renewal fees. The fees associated with obtaining the professional geoscientist license is $200 to cover the application and first- year license, and $150 per year after the first year.

Ms. Conrad also determined that for each of the first five years the proposed rules are in effect, the public benefit anticipated from the enforcement of and compliance with the proposed rules will be potentially improved environmental performance by persons regulated by the commission. The proposed rules might impact other state agencies or local governments with staff geologists who need to become licensed under these rules. No significant fiscal implications are anticipated for any individual or business due to implementation of the proposed rules. Additionally, no significant fiscal implications are anticipated for any small or micro-business due to implementation of the proposed rules. The commission has determined that a local employment impact statement is not required because the proposed rules do not adversely affect a local economy in a material way for the first five years that the proposed rules are in effect.

DRAFT REGULATORY IMPACT ANALYSIS DETERMINATION

The commission reviewed the proposed rulemaking in light of the regulatory analysis requirements of Texas Government Code, §2001.0225 and determined that the rulemaking is not subject to §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 proposed 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 proposed rules are not specifically intended to protect the environment or reduce risks to human health. The proposed 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 proposed 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 proposed rules do not meet the definition of major environmental rule.

Furthermore, even if the proposed 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 proposed amendments to Chapter 312 do not meet any of these requirements. First, there are no federal standards that these rules would exceed. Second, the proposed rules do not exceed an express requirement of state law. Third, there is no delegation agreement that would be exceeded by these proposed rules. Fourth, the commission proposes these rules to allow for the public practice of geoscience in agency procedures in conformance with the Act. Therefore, the commission does not propose the adoption of the rules solely under the commission's general powers.

The commission invites public comment on the draft regulatory impact analysis determination.

TAKINGS IMPACT ASSESSMENT

The commission evaluated these proposed rules and performed a preliminary assessment of whether these proposed rules constitute a takings under Texas Government Code, Chapter 2007. The specific intent of the proposed rules is to establish regulations allowing for the public practice of geoscience in agency procedures in conformance with the Act. The proposed 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 proposed rules would be neither a statutory nor a constitutional taking of private real property. Specifically, the proposed 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 proposed rulemaking. These proposed 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. These proposed 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 has reviewed the proposed rulemaking and found that the proposal 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), and will therefore require that applicable goals and policies of the CMP be considered during the rulemaking process. The commission has prepared a consistency determination for the proposed rules under 31 TAC §505.22 and found that the proposed rulemaking is consistent with the applicable CMP goals and policies. The following is a summary of that determination. The CMP goal applicable to the proposed 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 proposed 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 proposed 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 proposed rulemaking would require a person who prepares and submits geoscientific information to the agency to be a licensed professional geoscientist. The commission invites public comment on the consistency determination of the proposed rules.

Chapter 321. CONTROL OF CERTAIN ACTIVITIES BY RULE

The Texas Commission on Environmental Quality (commission) proposes amendments to §§321.32, 321.35, 321.39, 321.55, 321.252, 321.255, 321.271, and 321.274.

BACKGROUND AND SUMMARY OF THE FACTUAL BASIS FOR THE PROPOSED RULES

Senate Bill (SB) 405, 77th Legislature, established the Texas Board of Professional Geoscientists and the regulation of professional geoscientists. The 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 proposed 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

Throughout the sections, administrative changes are proposed in accordance with Texas Register requirements and to be consistent with other agency rules.

Proposed §321.32, 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 proposed to be added and the definition of qualified groundwater scientist is proposed to be deleted, and existing paragraphs (20) - (33) are proposed to be renumbered accordingly.

Proposed §321.35(c), Procedures for Making Application for Registration, makes minor grammatical corrections, substituting "that" for "which" and removing "such." In proposed subsection (c)(8), substitutes "shall" for "must" and requires that documentation of liner certifications be prepared, signed, sealed, and dated either by a licensed professional engineer or a licensed professional geoscientist. In subsection (c)(10), the commission proposes that a recharge feature certification may be made by a Natural Resources Conservation Service (NRCS) engineer, a licensed professional engineer, or a licensed professional geoscientist (rather than a qualified groundwater scientist). In subsection (c)(10)(G), licensed professional geoscientist is proposed to be substituted for qualified groundwater scientist, and a minor grammatical error is proposed to be corrected. In subsection (c)(11), the commission proposes to replace qualified groundwater scientist with licensed professional geoscientist; to correct two minor grammatical errors; and to break the final sentence into two sentences for readability. In subsection (c)(11)(B), the commission proposes to require that the groundwater monitoring plan be prepared, certified, signed, sealed, and dated by a licensed professional geoscientist and to substitute "must" for "shall." Cross-references in §321.35(b), (d), (e), and (h) are proposed to be updated.

Proposed §321.39(f), Pollution Prevention Plans, substitutes "must" for "shall." The commission proposes to amend subsection (f)(16) by making an antecedent noun agree in number with its precedent nouns; and substituting "that" for "which." In subsection (f)(16)(A), a minor grammatical correction in the choice of indefinite article is proposed; and licensed professional geoscientist is proposed to replace qualified groundwater scientist as one of the three people who may document no significant leakage from a retention structure. In subsection (f)(16)(B), the commission proposes to specify what the documentation must include or show; to correct a minor grammatical error; and to replace licensed professional geoscientist for qualified groundwater scientist as one of the three people who may make the written determination. In subsection (f)(17), the commission proposes to substitute "must" for "shall"; substitute "that" for "which"; correct a minor grammatical error; replace licensed professional geoscientist for qualified groundwater scientist as one of the three people who can make a site-specific assessment; make an antecedent noun agree in number with its precedent noun; and use the correct noun "equivalent" meaning "equal" rather than "equivalency," which means "a condition of equality." In subsection (f)(18), the commission proposes to make a precedent noun agree in number with its antecedent noun; correct a minor grammatical error; and replace licensed professional geoscientist for qualified groundwater scientist as one of the three people who can do a site evaluation every five years.

Proposed §321.55, Protection of Groundwater, substitutes "must" for "shall"; correctly specifies the requirements of paragraphs (1) and (2); and deletes the word "such." In paragraph (2), the commission proposes to substitute "must" for "shall"; delete an unnecessary period; spell out centimeters per second; provide the correct and proper name of the laboratory test to be conducted; and require certification of the pond liner by a licensed professional engineer or a licensed professional geoscientist and that the certification be signed, sealed, and dated by a licensed professional engineer or a licensed professional geoscientist.

Proposed §321.252, Definitions, amends the introduction of the section by adding the word "when"; deleting the word "shall"; and deleting the phrase "unless the context clearly indicates otherwise." The definition of licensed professional geoscientist is proposed to be added as new paragraph (6) and the remaining paragraphs are proposed to be renumbered accordingly. A corrected reference to Chapter 213 instead of Chapter 313 is proposed in renumbered paragraph (10). Formatting changes are proposed throughout this section to be consistent with other agency rules.

Proposed §321.255(c), Requirements for Containment of Wastes and Pond(s), substitutes "licensed" for "registered" professional engineer; includes a licensed professional geoscientist among the persons who can certify a pond lining; and substitutes "using" for "utilization of." Proposed subsection (c) also requires that the certification be signed, sealed, and dated by a licensed professional engineer or licensed professional geoscientist. Formatting changes are proposed throughout this section to be consistent with other agency rules. A cross-reference is proposed to be corrected in subsection (e).

Proposed §321.271, Definitions, amends the introduction of the section by deleting the word "shall" and the phrase "unless the context clearly indicates otherwise." The definition of licensed professional geoscientist is proposed to be added as new paragraph (14) and the remaining paragraphs are proposed to be renumbered accordingly. Administrative changes, which include formatting, grammatical, and cross-reference corrections, are proposed throughout the section to conform with Texas Register and agency requirements.

Proposed §321.274, Ground-water Protection, amends the title to Groundwater Protection, to reflect the accepted usage of "groundwater" as a single, unhyphenated word. Subsection (a) is proposed to be amended to substitute "that" for "which"; substitute "must" for "shall"; and spell out milligrams per liter. The commission proposes to amend subsection (a)(1) to substitute "must" for "shall"; eliminate a superfluous grammatical construction; and reflect the accepted usage of "groundwater" as a single, unhyphenated word. Subsection (a)(1)(E) is proposed to be amended to require that the certification be signed, sealed, and dated by a licensed professional engineer or licensed professional geoscientist; substitute "licensed" for "registered" professional engineer; include a licensed professional geoscientist among the persons who can certify a pond lining; and substitute "using" for "utilization of." The commission proposes to amend §321.274(b) by substituting "using" for "utilizing"; substituting "that" for "which"; specifying the noun antecedent of the demonstrative pronoun; and substituting "must" for "shall." Subsection (b)(1) is proposed to be amended to substitute "must" for "shall"; eliminate a superfluous grammatical construction; and reflect the accepted usage of "groundwater" as a single, unhyphenated word. The commission proposes to amend subsection (b)(1)(D) to require that the certification be signed, sealed, and dated by a licensed professional engineer or licensed professional geoscientist; substitue "licensed" for "registered" professional engineer; include licensed professional geoscientist among the persons who can certify a pond lining; and substitute "using" for "utilization of." Formatting changes are proposed throughout this section to be consistent with other agency rules.

FISCAL NOTE

Doretta Conrad, Analyst in the Budget and Planning Division, has determined that, for the first five-year period the proposed rules are in effect, there will be no significant fiscal implications for the agency or any other unit of state government as a result of administration or enforcement of the proposed rules. There will be no fiscal impact to the agency; however, there may be fiscal implications to the agency if the agency elects to reimburse staff for the annual renewal fees. The fees associated with obtaining the professional geoscientist license is $200 to cover the application and first-year license, and $150 per year after the first year.

Ms. Conrad also determined that for each of the first five years the proposed rules are in effect, the public benefit anticipated from the enforcement of and compliance with the proposed rules will be potentially improved environmental performance by persons regulated by the commission. The proposed rules might impact other state agencies or local governments with staff geologists who need to become licensed under these rules. No significant fiscal implications are anticipated for any individual or business due to implementation of the proposed rules. Additionally, no significant fiscal implications are anticipated for any small or micro-business due to implementation of the proposed rules. The commission has determined that a local employment impact statement is not required because the proposed rules do not adversely affect a local economy in a material way for the first five years that the proposed rules are in effect.

DRAFT REGULATORY IMPACT ANALYSIS DETERMINATION

The commission reviewed the proposed rulemaking in light of the regulatory analysis requirements of Texas Government Code, §2001.0225 and determined that the rulemaking is not subject to §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 proposed 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 proposed rules are not specifically intended to protect the environment or reduce risks to human health. The proposed 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 proposed 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 proposed rules do not meet the definition of major environmental rule.

Furthermore, even if the proposed 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 proposed amendments to Chapter 321 do not meet any of these requirements. First, there are no federal standards that these rules would exceed. Second, the proposed rules do not exceed an express requirement of state law. Third, there is no delegation agreement that would be exceeded by these proposed rules. Fourth, the commission proposes these rules to allow for the public practice of geoscience in agency procedures in conformance with the Act. Therefore, the commission does not propose the adoption of the rules solely under the commission's general powers.

The commission invites public comment on the draft regulatory impact analysis determination.

TAKINGS IMPACT ASSESSMENT

The commission evaluated these proposed rules and performed a preliminary assessment of whether these proposed rules constitute a takings under Texas Government Code, Chapter 2007. The specific intent of the proposed rules is to establish regulations allowing for the public practice of geoscience in agency procedures in conformance with the Act. The proposed 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 proposed rules would be neither a statutory nor a constitutional taking of private real property. Specifically, the proposed 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 proposed 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. These proposed 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 has reviewed the proposed rulemaking and found that the proposal 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), and will therefore require that applicable goals and policies of the CMP be considered during the rulemaking process. The commission has prepared a consistency determination for the proposed rules under 31 TAC §505.22 and found that the proposed rulemaking is consistent with the applicable CMP goals and policies. The following is a summary of that determination. The CMP goal applicable to the proposed 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 proposed 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 proposed 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 proposed rulemaking would require a person who prepares and submits geoscientific information to the agency to be a licensed professional geoscientist. The commission invites public comment on the consistency determination of the proposed rules.

§321.39.Pollution Prevention Plans.

(a) (No change.)

(b) Where a Natural Resources Conservation Service (NRCS) plan has been prepared for the facility, the pollution prevention plan may refer to the NRCS plan when the NRCS plan documentation contains equivalent requirements for the facility. When the operator uses an [ a ] NRCS plan as partial completion of the pollution plan, the NRCS plan must be kept on site. Design and construction criteria developed by the NRCS can be substituted for the documentation of design capacity and construction requirements (see subsection (f) of this section) of the pollution prevention plan provided the required inspections logs and water level logs in subsection (f)(3) and (11) of this section are kept with the NRCS plan [ Plan ]. Waste management plans developed by the NRCS can be substituted for the documentation of application rate calculations in subsection (f)(19) and (24) of this section. NRCS Waste Management Plans which have been prepared since January 1, 1989 are considered by the NRCS to contain adequate management practices. To insure the protection of water quality, the NRCS has determined that NRCS plans prepared prior to 1989 must be submitted for renewal with the NRCS [ Natural Resources Conservation Service ] or a waste management professional before December 1995. NRCS has determined that all plans should be reviewed every five years to insure proper management of wastes.

(c)-(e) (No change.)

(f) The plan must [ shall ] include, at a minimum, the following items.

(1)-(15) (No change.)

(16) The operator shall include in the plan, site-specific documentation that no significant hydrologic connection exists between the contained wastewater and waters in the state. Where the operator cannot document that no significant hydrologic connection exists, the ponds, lagoons, and basins of the retention facilities must have liners that [ a liner which ] will prevent the potential contamination of surface waters and groundwaters.

(A) The operator can document lack of hydrologic connection by either: documenting that there will be no significant leakage from the retention structure; or documenting that any leakage from the retention structure would not migrate to waters in the state. This documentation shall be certified by an [ a ] NRCS engineer, licensed professional engineer, or licensed professional geoscientist [ qualified groundwater scientist ] and must include information on the hydraulic conductivity and thickness of the natural materials underlying and forming the walls of the containment structure up to the wetted perimeter.

(B) For documentation of no significant leakage, in-situ materials must, at a minimum, meet the minimum criteria for hydraulic conductivity and thickness as described in this section. Documentation that leakage will not migrate to waters in the state must include maps showing groundwater flow paths, or must show that the leakage enters a confined environment. A written determination by an [ a ] NRCS engineer, licensed professional geoscientist, or a licensed professional engineer that a liner is not needed to prevent a significant hydrologic connection between the contained wastewater and waters in the state will be considered documentation that no significant hydrologic connection exists.

(17) Site-specific conditions must [ shall ] be considered in the design and construction of liners. NRCS liner requirements or liners constructed and maintained in accordance with NRCS design specifications in Appendix 10d of the Agricultural Waste Management Handbook (or its current equivalent) shall be considered to prevent hydrologic connections that [ which ] could result in the contamination of waters in the state. Liners for retention structures must [ shall ] be constructed in accordance with good engineering practices. Where no site-specific assessment has been done by an [ a ] NRCS engineer, licensed professional engineer, or licensed professional geoscientist [ qualified groundwater scientist ], the liner must [ shall ] be constructed to have a hydraulic conductivity [ conductivities ] no greater than 1 x 10 -7 centimeters per second [ cm/sec ], with a thickness of 1.5 feet or greater or its equivalent [ equivalency ] in other materials.

(18) Where a liner is installed to prevent hydrologic connection , the operator must maintain the liner to inhibit infiltration of wastewaters. Liners must [ shall ] be protected from animals by fences or other protective devices. No tree [ trees ] shall be allowed to grow within the potential distance of the tree's root zone. Any mechanical or structural damage to the liner must [ shall ] be evaluated by an [ a ] NRCS engineer or a licensed professional engineer within 30 days of the damage. Documentation of liner maintenance must [ shall ] be kept with the pollution prevention plan. The operator shall have an [ a ] NRCS engineer, licensed professional engineer, or licensed professional geoscientist [ qualified groundwater scientist ] review the documentation and do a site evaluation every five years. If notified by the executive director that significant potential exists for the contamination of waters in the state or drinking water, the operator shall install a leak detection system or monitoring well(s) in accordance with that notice. Documentation of compliance with the notification must be kept with the pollution prevention plan, as well as all sampling data. In the event monitoring well(s) are required, the operator must sample each monitor well annually for nitrate as nitrogen, chloride, and total dissolved solids using the methods outlined in the pollution prevention plan, and compare the analytical results to the baseline data. If a 10% deviation in concentration of any of the sampled constituents is found, the operator must notify the executive director within 30 days of receiving the analytical results. Data from any monitoring wells must be kept on site for three years with the pollution prevention plan. The first year's sampling shall be considered the baseline data and must be retained on site for the life of the facility unless otherwise provided by the executive director.

(19)-(30) (No change.)

(31) Operators submitting applications for renewal or expansion of existing facilities authorized under this subchapter to utilize a playa lake as a wastewater retention structure shall within 90 [ ninety (90) ] days of the effective date of the renewal, submit a groundwater monitoring plan to the Agriculture Section, Water Quality Division of the Texas [ Natural Resource Conservation ] Commission on Environmental Quality . At a minimum, the groundwater monitoring plan shall specify procedures to annually collect a groundwater sample from each well providing water for the facility, have each sample analyzed for chlorides and nitrates, and compare those values to background values for each well.

This agency hereby certifies that the proposal has been reviewed by legal counsel and found to be within the agency's legal authority to adopt.
